Product Description: Y-Type Anti-Spill Skirtboard with Dual Sealing Coal GuardThe anti-spill skirtboard is an automatic adjustment conveyor belt skirt system designed to prevent overflow and spillage. The Y-type anti-spill skirtboard consists of a main seal and an auxiliary seal, forming a dual sealing mechanism. It is soft, wear-resistant, and fits tightly against the belt through the elasticity of the sealing strip itself. The multi-layer protection of the main and auxiliary seals collects dust to achieve the purpose of preventing overflow.The anti-spill skirtboard adopts an integrated structure with a straight plate and T-shaped foot or a Y-type structure, and can also be processed and produced according to the actual needs of customers. The straight plate height is 250mm (or processed according to actual dimensions), with a thickness of not less than 20mm, adjustable as per customer requirements. The T-shaped foot width is not less than 50mm (adjustable according to customer requirements).The anti-spill skirtboard for the chute produced by our company is optimally designed based on the operating characteristics of the belt and the structure of the chute, incorporating the advantages of various types of anti-spill skirtboards both domestically and internationally.1. The inclined surface of the vertical plate has the same angle as the buffer idler, featuring dual-layer sealing for effective sealing performance.2. Made entirely of polyurethane material, it has a long service life and does not damage the belt.3. The side sealing can be adjusted according to the distance between the belt edge and the chute. High-quality side sealing combines well with the belt, avoiding cutting of the side plate.4. The sealing groove of the side sealing adopts a single-sided arc transition, which prevents cutting of the side seal when the belt deviates and allows automatic restoration to the original state.5. The pressing device can self-adjust the pressure on both sides of the angle steel, ensuring even pressure and preventing the side seal from falling off.6. Installation and adjustment are convenient and simple.Some coal mining units use old belts instead of anti-spill skirtboards for sealing the chute to save production costs. However, old belts do not fit well, are not wear-resistant, and have poor sealing performance.The length of the anti-spill skirtboard can be freely cut by users according to their needs, with a width generally between 150-350mm and a thickness of 15mm. Other specifications can be custom-made as required. The anti-spill skirtboard is fixed using specialized clamps. For every meter of anti-spill skirtboard purchased, one meter of angle aluminum and two clamps are provided.Advantages of the Chute Anti-Spill Skirtboard:1.It uses multiple protective sealing strips for sealing, which improves efficiency compared to ordinary single-piece rubber anti-spill skirts by a factor of 2. It also provides an additional sealing space compared to dual-seal anti-spill skirts, further enhancing performance.2.The main body of the anti-spill skirtboard—chute anti-spill skirtboard—is black, made from high-quality imported natural rubber and styrene-butadiene rubber through mixing. It maintains stiffness while increasing elasticity, allowing the green multi-protective sealing strips to fit tightly against the conveyor belt. Even after the multi-protective system reaches the end of its service life, it can continue to perform the duties of an anti-spill skirtboard, protecting the user's belt from damage.

Product Description: 6mm Rubber Seal Strip for Feed Chute Dust CurtainFunction and Advantages of Dust CurtainsThe primary function of dust curtains is to block and filter coal dust. Through this process, the concentration of coal dust can be significantly reduced, purifying the air. Additionally, the purification spray device installed in front of the dust curtain can moisten and wash the coal dust, flushing it down to the roadway floor to form deposited coal dust, further reducing the amount of airborne dust. The use of dust curtains not only enhances the safety of the working environment but also extends the service life of equipment and reduces production costs.ConclusionMining dust curtains are an indispensable part of mine dust control. Through effective blocking and filtration, as well as moistening and washing measures, they significantly reduce the concentration of coal dust, achieving effective dust removal in mines. The material and design of dust curtains need to be selected and customized based on specific working environments and requirements to ensure they deliver the maximum dust control effect.Material SelectionThe main materials for dust suppression curtains include polyethylene, polyurethane, rubber, and EPDM. Different materials offer varying performance characteristics. For example, polyurethane dust curtains exhibit excellent weather resistance, high-temperature aging resistance, as well as good environmental and insulation properties. When selecting materials, factors such as the working environment's temperature, humidity, abrasion resistance, and chemical resistance must be considered.PrecautionsDuring the installation and use of dust suppression curtains, regular maintenance and cleaning are essential to ensure their effectiveness. At the same time, the type, size, and installation location of the dust curtain should be reasonably selected based on the actual site conditions and requirements. more>

Product Description: The Xenon Arc Weathering Tester for High-Transparency Plastic Materials is a key method for evaluating the weatherability of high-transparency plastics (such as PC and high-transparency PVC). By simulating natural climate conditions including light exposure, temperature, and humidity, it predicts the performance changes of materials during long-term use. The following is a detailed analysis:I. Testing Principles and EquipmentLight Source SimulationThe xenon arc weathering chamber uses a high-pressure xenon lamp as the light source, with a spectral energy distribution highly similar to sunlight, covering ultraviolet (UV), visible light, and infrared (IR) radiation. A filtering system removes ultraviolet light below 290 nm and infrared light above 1200 nm, making the spectrum received by the sample surface closer to natural sunlight.Environmental ControlThe test chamber is equipped with temperature and humidity control systems, allowing adjustment of temperature (typically 20°C to 60°C) and humidity (e.g., 50% RH to 95% RH) to simulate various climate conditions. Some devices also include a spray system to simulate the effects of rainfall on materials.Sample Holder and SensorsThe sample holder secures test specimens to ensure uniform light exposure; sensors (such as 340 nm and 420 nm irradiance calibrators) monitor irradiance levels in real time to ensure consistent testing conditions.II. Testing Standards and ParametersInternational StandardsISO 4892-2: Plastics — Methods of exposure to laboratory light sources, Part 2: Xenon-arc lamps.ASTM G155: Standard Practice for Operating Xenon Arc Light Apparatus for Exposure of Non-Metallic Materials, applicable to plastics, coatings, etc.ASTM D2565: Standard Practice for Xenon Arc Exposure of Plastics Intended for Outdoor Applications.GB/T 16422.2: Chinese National Standard, similar to ISO 4892-2.Key ParametersIrradiance: Typically set at 0.35–0.55 W/m²/nm (at 340 nm wavelength).Black Panel Temperature: Simulates material surface temperature, generally set at 65°C ± 3°C.Humidity: Set according to testing requirements, e.g., 50% RH (dry) or 95% RH (wet).Light/Dark Cycles: Simulates day-night alternation, e.g., 102 minutes of light + 18 minutes of dark.Test Duration: Typically 200 hours per cycle, extendable to 800 hours or longer based on requirements.III. Testing ProcessSample PreparationCut samples according to standard requirements, ensuring clean surfaces free of defects (e.g., scratches, stains).Sample dimensions must meet chamber requirements, usually 75 mm × 150 mm or larger.Parameter SettingSet irradiance, temperature, humidity, and other parameters based on standards or client requirements.For example: ISO 4892-2 Method A requires a black panel temperature of 65°C ± 3°C and relative humidity of 50% ± 10%.Test ExecutionSecure samples on the holder and start the chamber for continuous aging exposure.Regularly inspect samples and record changes in color, gloss, mechanical properties, etc.Result EvaluationColor Change: Use a colorimeter to measure ΔE values and assess fading.Gloss Change: Measure with a gloss meter to evaluate surface aging.Mechanical Properties: Test tensile strength, impact strength, etc., to analyze changes in material toughness.Surface Morphology: Use microscopy or scanning electron microscopy to observe defects like cracking and chalking.IV. Key Testing Focus for High-Transparency Plastic MaterialsLight Transmittance RetentionHigh-transparency plastics (e.g., with transmittance up to 93%) require close monitoring of transmittance changes after aging.For example: PC materials should exhibit a transmittance decrease of less than 5% after 1000 hours of xenon arc aging.Yellowness Index (YI)Evaluate whether materials yellow due to UV exposure, affecting appearance and transparency.For example: High-transparency PVC with anti-aging additives can maintain a yellowness index below 3.Weathering Resistance OptimizationAdditives: Such as UV absorbers (e.g., UV-327) and light stabilizers (e.g., HALS) to extend material service life.Surface Coatings: Apply anti-UV coatings to reduce photodegradation effects.V. Xenon Arc Weathering Tester for High-Transparency Plastic Materials Applications and Case StudiesAutomotive IndustryTest Objects: Headlight lenses, interior parts (PC/ABS).Standards: SAE J2412 (interior components), SAE J1960 (exterior components).Case Study: A car model’s headlight lens maintained ≥90% light transmittance after 2000 hours of xenon arc aging, meeting design requirements.Construction IndustryTest Objects: Skylight panels (PC), transparent doors and windows (high-transparency PVC).Standards: ASTM D4434 (roofing materials), GB/T 8427 (textile colorfastness to light).Case Study: PC skylight panels used in a construction project showed no cracking or chalking after 5000 hours of xenon arc aging.Consumer Goods IndustryTest Objects: Transparent water bottles (Tritan), cosmetic bottles (PET).Standards: AATCC 16-2004 (indoor textiles), ISO 105-B02 (textile colorfastness to light).Case Study: A brand’s transparent water bottle exhibited ≤15% decrease in tensile strength after 800 hours of xenon arc aging, complying with safety standards.VI. Testing Significance and ValueQuality Control: Simulates natural aging to detect material defects early, preventing product failures after market release.Lifetime Prediction: Uses accelerated aging data to estimate material service life in real-world conditions (e.g., 10 years outdoors equivalent to 5000 hours of xenon arc aging).Cost Optimization: Reduces outdoor testing cycles (typically 1–2 years) and lowers R&D costs. more>

Product Description: I. Definition of a Blow Tank:The blow tank is a device used for conveying powdered and granular materials (suitable media: powder, coal, ash). The working process involves storing the material in the tank body of the blow tank, fluidizing the material with compressed air, and then conveying it through a pipeline to the destination under the action of a pressure differential.II. Working Principle of the Pneumatic Conveying Blow TankIn the pneumatic conveying process, the blow tank plays a crucial role. The specific working process can be broadly divided into the following three steps:Process 1: Feeding. Material first enters the blow tank body through the feed inlet. Feeding is typically completed via an automated feeding device (conveyor), but manual feeding is also possible. When the material level in the tank reaches a certain point, the feeding action is completed.Process 2: Fluidization. During the material conveying stage, compressed air enters the blow tank body through a fluidization device at the bottom (such as an aeration pad or fluidizing nozzle). The fluidization device ensures that compressed air is evenly distributed at the bottom of the material, causing it to become fluidized. In this fluidized state, the material can flow like a liquid under the push of air pressure.Process 3: Conveying. After the material is fluidized, the discharge valve opens. The internal pressure of the tank is higher than that in the conveying pipeline. Under the action of the pressure differential, the fluidized material is pushed into the conveying pipeline. Within the pipeline, the material is conveyed as a gas-solid two-phase flow, meaning the material particles are suspended in the air stream and move forward with the airflow, eventually reaching the destination.The above describes the complete working process of a pneumatic conveying blow tank, which can significantly improve the efficiency of material conveying, making the entire process more energy-efficient and environmentally friendly, while also saving substantial labor. Selecting a blow tank requires expertise; different conveying media have varying material properties, with different requirements for temperature resistance, wear resistance, and corrosion resistance. Different production conditions also demand different blow tank sizes, making it particularly important to choose a service provider with extensive experience in pneumatic conveying projects. Northern Pressure Vessel (Jinan) Co., Ltd. has experience in project design, manufacturing, and installation, serving leading enterprises in various fields such as power, energy, petroleum, and coal chemical industries, with strong professional service capabilities.

Product Description: The air shower is an essential passage for personnel entering the cleanroom. It helps reduce contamination issues caused by entering and exiting the cleanroom. By installing a fully functional "airlock chamber" at the entrance of the cleanroom, the amount of airborne particulate contamination can be minimized. When personnel or goods pass through the air shower, contaminants are blown away by highly purified air filtered through high-efficiency filters. A high wind speed of over 25 m/s ensures effective removal of particles, which are essentially filtered out by primary and high-efficiency two-stage filters. To maintain the safe use of the air shower and preserve the cleanliness of the cleanroom environment.1. Before entering the cleanroom, outer clothing should be removed in the outer changing room, and items such as watches, mobile phones, and accessories should be taken off.2. Enter the inner changing room and put on cleanroom garments, caps, masks, and gloves.3. After pulling open the stainless steel air shower door and entering the air shower, the outer door will automatically close. Infrared sensors will detect presence, and the air shower will automatically activate for a 15-second blow-off.Factors affecting the air quality in the air shower:1. Personnel working in the cleanroom must strictly adhere to cleanroom operating procedures. Cleanroom doors and windows should remain closed at all times. There should be a buffer zone for the transfer of personnel and items between clean and non-clean areas, equipped with air shower devices to prevent airflow convection. Unauthorized personnel should not enter the cleanroom.2. The air change rate in the cleanroom and the supply air volume of the HVAC purification system are the main internal factors maintaining positive pressure and cleanliness, but they are constrained by the final resistance of various filters in the purification system.3. Equipment in the cleanroom requires regular, scheduled cleaning and maintenance by designated personnel. The materials and cleaning liquids used must comply with cleanroom management standards.4. For users, the cleanliness level of the cleanroom is their primary concern. The biggest sources of contamination in an operational cleanroom are people and items entering the room. Dust particles generated during production are another factor affecting indoor cleanliness.5. Proper separation of human and material flows is crucial for maintaining cleanliness in the air shower room. Before entering the cleanroom, personnel should change clothes and undergo air showering, ensuring their attire meets cleanroom management standards. In some high-cleanliness production processes, personnel may even need to shower before entry. Similarly, items should be repackaged and air-showered before entering the cleanroom, and the repackaged materials must meet cleanroom standards.Air showers are used in various cleanrooms and non-cleanrooms across industries such as microelectronics, optoelectronics, semiconductors, pharmaceuticals, food, chemicals, aviation, automotive, printing, and laboratories. They are essential for removing particles larger than 0.3 microns from personnel before entering high-cleanliness areas, preventing contamination. Additionally, they serve as an airflow buffer, as opening doors can cause air movement. The air shower effectively contains airflow within itself, minimizing the risk of air pollution caused by air movement.The air shower is a purification device for personnel entering cleanrooms and is highly versatile, compatible with all types of cleanrooms and clean facilities. When staff enter the workshop, this device uses powerful, clean air sprayed from rotating nozzles in all directions to effectively and quickly remove dust, hair, debris, and other particles attached to clothing. It significantly reduces contamination issues associated with personnel entering and exiting cleanrooms. more>

Product Description: Air Shower: Air showers are divided into manual air showers and fully automatic air showers. The conventional size for manual ones is 1000*1400*2150mm, while for fully automatic ones, it is 1000*1700*2200mm. 1. Material: SUS304 stainless steel, with a 304 embossed anti-slip plate at the bottom.2. Visible 3C certified safety tempered glass, 5mm thick, fixed with aluminum strips and silicone-free sealant.3. Nozzles: 20 nozzles per meter, multi-angle embedded adjustable mirror-polished stainless steel nozzles, with a surface wind speed of 22~25m/s, meeting industry standards. Air is blown from both sides and the top, totaling three sides, ensuring excellent air shower effects. The inner blowing height ranges between 650~1500(mm). The return air position is on the inner side, between 70~450(mm) from the bottom. The air shower operates as an internal circulation system: the high-pressure centrifugal fan in the fan box generates air that enters the air plenum, passes through the high-efficiency filter, and forms high-pressure airflow through stainless steel nozzles, blowing into the air shower channel. The negative pressure created by the rotation of the high-pressure centrifugal fan's impeller then draws the air from the air shower channel back into the fan box through the return air outlet.4. Filter: The air shower uses 4 sets of partitioned high-efficiency filters with a filtration efficiency of H13 (MPPS). The filter size is 570*375*50, ensuring uniform return air.5. Fan configuration: Equipped with specialized air shower fans—low-noise, high-airflow centrifugal fans. Two 0.75KW high-pressure centrifugal fans per meter ensure effective blowing. Parameters of the centrifugal fans are as follows: flow rate: 2550m³/h, total pressure: 1150Pa, noise ≤78dB, speed: 2840r/min, voltage: 380V, frequency: 50Hz. The voltage is 380V, and the total power is 4.5KW.6. Safety: Automatic doors come with anti-pinch devices; in case of sudden power failure while someone is inside the air shower, the inner and outer doors can be manually opened for safe exit.7. Uses high-quality Opple LED ultra-thin embedded downlights, ceiling-mounted, with delayed lighting function. The lights turn on when the door opens and delay for 60 seconds after the air shower ends before turning off.8. Circuit control: The air shower control panel and circuit are designed and developed in-house, featuring advanced high-tech integrated circuit control with photoelectric sensors. The text display shows internal blowing, lighting, and adjustment time buttons. The air shower time is adjustable from 0 to 99 seconds. An LED display shows door status, fan activation status, and air shower time. The dual-door indicator system uses advanced integrated circuits for sensor-activated automatic blowing. When a person enters the air shower, the sensor automatically detects and initiates blowing (entering from the exit door does not trigger blowing, making the program more advanced and intelligent). It includes two blowing modes: intercept and direct, which can be manually switched on the control panel, and features an emergency stop function. more>
