Product Description: Long-lasting pad printing silicone with no oil seepage or sticky residue, offering extended service life and high print countsApplications of Pad Printing Silicone:Pad printing silicone is specifically used for manufacturing pad printing pads. It is primarily applied in printing on plastic toys, electroplated products, electronic toys, trademarks, and irregular patterns. The pad printing pad acts as a carrier to transfer patterns from the steel plate onto toy products.Features of Pad Printing Silicone:1); Low viscosity, good fluidity2); No shrinkage, easy ink application, clear printed patterns3); Fine texture, excellent rebound, high number of printing cycles4); Professional-grade pad printing silicone is designed for manufacturing printing pads. It requires a fine texture, free of impurities and particles, with good rebound. Made from high-quality raw materials and enhanced with DuPont's high-temperature resistant new material, it offers advantages such as wear resistance, high-temperature tolerance, and excellent printing results.Operation of Pad Printing Silicone:① First, clean the mold thoroughly with detergent, then wipe or blow dry any moisture, and apply a layer of release agent.② The standard ratio of pad printing silicone to silicone oil is determined based on customer requirements. If the customer needs to print large patterns and requires a softer pad, more silicone oil should be added. Conversely, for a harder pad, little or no silicone oil should be added. Generally, the hardness of a pad printing pad should be between 15A° and 25A°. Excessive silicone oil will make the pad too soft, limiting the number of prints. Even the highest quality silicone can be compromised by excessive silicone oil, leading to reduced wear resistance, solvent resistance, and accelerated aging.③ A typical ratio is as follows: 100g of silicone with 30g of silicone oil, resulting in a pad hardness of 20A°, suitable for printing small patterns on alloy car models and products with small contact areas. For larger contact areas or softer pads, ratios such as 100:30 or 100:50 can be used. However, note that higher silicone oil content softens the pad, reducing the number of prints, wear resistance, and solvent resistance. This increases costs and wastes materials.④ The curing agent ratio and chemical reaction of silicone are as follows: Take 100g of silicone and 50g of silicone oil, mix thoroughly. After ensuring even distribution, add 2%–3% of the total weight of silicone and silicone oil as curing agent, then stir for another 2–3 minutes. Proceed to degassing, which should not exceed 10 minutes. Excessive degassing time may cause premature curing, affecting the quality of the silicone.Principles of Pad Printing Pad Manufacturing:a.; The vulcanization system of rubber is the foundation of significant advancements in the rubber industry. Pad printing pads are made using the principle of room-temperature vulcanized silicone rubber cross-linking into a network-structured elastomer under the action of vulcanizing agents.b.; Rubber consists of large molecular chain hydrocarbons. Rubber with only carbon atoms in the main chain is called carbon-chain rubber; rubber with other atoms besides carbon in the main chain is called heterochain rubber. If the main chain contains organic groups with atoms like silicon (Si), tin (Sn), or boron (B), it is termed an elemental organic polymer. Silicone rubber is an elemental organic polymer with organosilicon groups in its main chain. There are two vulcanization processes for silicone rubber: high-temperature vulcanization, corresponding to high-temperature vulcanized silicone rubber (HTV), and room-temperature vulcanization, corresponding to room-temperature vulcanized silicone rubber (RTV). RTV silicone rubber is further divided into addition-type and condensation-type.c.; Condensation-type silicone rubber contains terminal hydroxyl groups (-OH), which easily react with silanes containing hydrolyzable groups (-OCH3, -OCOCH3) for room-temperature vulcanization. The cross-linking agent is ethyl silicate, and the catalyst is dibutyltin dilaurate. Addition-type silicone rubber typically contains -CH=CH terminal groups and usually uses polysiloxane with Si-H bonds as a cross-linking agent for self-addition reactions to form an elastomer.  more>

It is widely used in common machine components such as cable ties, screws, bolts, nuts, and even plastic gears. Of course, compared to other plastic materials, it requires higher printing temperatures, making its use more professional. Today, we would like to share the advantages of using nylon material for custom gears.What is nylon material suitable for? The greatest advantage of nylon material is its applicability to various printing methods.1) Fused Deposition Modeling (FDM)This is one of the commonly used printing methods, which uses nylon filament for printing. With FDM technology, it is easy to produce prototypes, but due to nylon's susceptibility to moisture, achieving a smooth finished product can be relatively challenging. For better results, drying before use can reduce humidity.2) Multi Jet Fusion (MJF)This is a non-laser sintering powder material 3D printing technology that uses localized heating and a movable print head. It does not require drying all materials, but a relatively moisture-free environment is still needed for optimal results.3) Selective Laser Sintering (SLS)SLS ensures a certain level of precision and can use different types of nylon and composite materials. This method is suitable for printing highly complex structures, but attention must be paid to deformation issues caused by thermal shrinkage. more>

Category: Instruments & Meters/Optical Instruments/Optical Filters

Company: Zhongshan Xinzhao Optoelectronic Technology Co., Ltd

Product Description: A spectroscope is an optical component that splits a beam of light into two beams with specific reflection and transmission ratios. Its core principle involves using a dispersion element (such as a prism) to decompose white light into light of different wavelengths, forming a continuous visible light spectrum. This characteristic allows the selective absorption patterns of pigments in gemstones to be used for gem identification, determining the type of gemstone and the cause of its coloration by identifying fixed absorption band positions. In optical paths, the spectroscope primarily functions to separate light source energy and alter the direction of the light path. It features a simple structure, minimal light absorption, and low loss after spectral splitting.Classification and Structural Characteristics of SpectroscopesClassification by Structural FormCube Spectroscope: Composed of two right-angle prisms bonded together, with one prism's斜面 coated with a spectral splitting film, forming a cubic structure. Its advantages include high effective diameter utilization in all directions and ease of optical adjustment, making it suitable for compact optical systems. However, large-aperture products are heavier and more costly, and may produce a small amount of back-reflected light (within 1%).Plate Spectroscope: Designed based on a flat glass plate with a single surface coated with a spectral splitting film. It offers lower cost and lighter weight, making it suitable for applications with limited space or cost sensitivity. However, it suffers from issues such as optical path differences between reflected and transmitted light, which may cause astigmatism and beam displacement. At a 45° incidence angle, the effective diameter appears elliptical. 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>

Company: Baoding Chili Mold Manufacturing Co., Ltd.

Product Description: The U-shaped drainage channel steel mold demonstrates its functionality here. It is a tool for producing U-shaped drainage channel molds, shaping concrete in a short time with simple operation, making it suitable for application in various regions. As the role of the U-shaped drainage channel steel mold becomes evident, naturally, more and more units will purchase corresponding U-shaped drainage channel steel molds for concrete pouring and molding.The drainage channel steel mold is formed through multiple processes such as continuous laser cutting, trimming, welding with uniform and neat weld points, bending, and polishing according to the drawings. This steel plate is divided into two parts: one is the panel, with a thickness of 3-4mm, forming a smooth and flat surface; the other is reinforced with rib plates (4-8mm thick), making it 2-3mm thicker than the panel. In addition, it includes fixed pipes and small screws, among other components. The wall thickness of the drainage channel steel mold ranges from 10-20cm. In practice, each drainage channel mold requires customized steel plate thickness based on actual needs and dimensions to ensure the mold remains deformation-free, sturdy, and durable during later use. This means that the larger the size of the drainage channel steel mold, the thicker the steel plate, maintaining a proportional relationship.Common dimensions for U-shaped drainage channel molds include precast blocks generally over 1 meter in length, with internal depth and width typically measuring 40*40, 50*50, 80*80, or 100*100. These dimensions are commonly used and convenient for application. Vertical molds are often chosen for easier production. However, in many environments, mold dimensions are customized due to varying requirements based on usage conditions. Over a decade of producing drainage channel molds and U-shaped drainage channel steel molds, manufacturers have not only summarized production experience for such templates but also extended it to other types of sink molds derived from these, such as rectangular channels and drainage channel molds. Although their shapes or sizes may differ, the production technology principles remain the same. Cement precast components achieve high efficiency in molding, convenient construction, and more guaranteed construction quality, enabling safe and effective achievement of construction goals. more>

Company: 山东玖锌特种涂料有限公司

Product Description: Product Features: Long-lasting: Dry film zinc content ≥96%, salt spray resistance ≥3000 hours, the coating system has a corrosion protection cycle of over 25 years, with similar products abroad having successful examples of over 50 years; Environmental friendliness: Free from heavy metals such as lead and chromium, and organic solvents like toluene, xylene, methylene chloride, and methyl ethyl ketone.Anti-slip: Anti-slip coefficient ≥0.55, suitable for corrosion protection on high-strength bolt connection surfaces;  Design Purpose: Cold galvanizing paint provides dual functions of cathodic protection and barrier protection.Barrier protection: When zinc-rich cold spray zinc coating is oxidized, it forms a layer of zinc salts on the surface to provide barrier protection. Meanwhile, the binder in the cold spray zinc coating offers an additional layer of barrier protection, slowing down zinc oxidation. Therefore, the corrosion resistance of cold spray zinc coatings is superior to that of sprayed zinc (aluminum), hot-dip galvanizing, and other zinc-rich coatings.Active cathodic protection:Cold galvanizing paint differs from ordinary coatings, as its dry film contains over 96% pure zinc, providing excellent cathodic protection for steel.Even in harsh environments, it offers long-term protection for steel surfaces. Its corrosion resistance is comparable to hot-dip galvanizing,or even superior.1. Used for long-term corrosion protection of steel, replacing hot-dip galvanizing and thermal spray zinc, achieving better protective effects than hot-dip galvanizing and thermal spray zinc.2. Can be used as a single-layer metal anti-corrosion protective layer or as a primer in heavy-duty anti-corrosion coating systems for extended protection periods.3. Also suitable for repairing damages on various galvanized layers of steel structures caused by welding, cutting, drilling, or riveting.4. Widely applicable to various steel components and facilities, such as power transmission and distribution systems, power generation systems, bridges, building steel structures, concrete mixing plant steelstructures, towers, tunnel facilities, containers, ships, port facilities, hydraulic gates and their附属 steel structures, reinforcement bars, vehicle bodies, pipelines,tanks, silos, signs, fences, heating facilities, roof steel structures, etc.Compatible Products: Cold galvanizing paint can be used with epoxy mica iron oxide intermediate coat and then coated with various topcoats;Recommended topcoat compatible coatings: Epoxy resin paint, acrylic polyurethane paint, polysiloxane topcoat, fluorocarbon paint.Construction Process: Shot blasting for rust removal → drying with compressed air to remove dust → pre-coating of special areas like welds with zinc-rich coating → spray (brush) application of zinc-rich coating → coating interval → spray (brush) application of compatible coatings for zinc-rich coating → product quality inspection → qualifiedSurface Treatment: The surface should be sandblasted or shot blasted to achieve Sa2.5 grade as per GB8923 "Rust Grades and Preparation Grades of Steel Surfaces Before Coating." For areas where pretreatment does not meet requirements, use electric grinders to achieve St3 grade.Application Methods:Pre-coating: Use a brush to apply one coat on welds, corners, edges, screw holes, plate edges, and hard-to-reach areas for pre-coating. Air spray: Connect air source to an oil-water separator, use a 2.5mm nozzle for air spray, maintain a distance of about 25cm between the gun and the object surface, spray width approximately 15cm, apply two passes, wait 1 hour before applying the second coat with two cross passes to achieve the required thickness. Airless spray: Use specialized spraying equipment for zinc-rich coatings with a Z-type nozzle, ensure the entire equipment is clean, recommended compression ratio around 1:30, spray width about 25cm.Brush application: Use high-quality brushes that do not shed fibers, apply evenly using a cross method to ensure good penetration of the coating, avoid sagging and unevenness.Construction Guidance:Note: Theoretical consumption is calculated based on parameters; actual consumption may vary significantly depending on the user's application method, the shape of the sprayed workpiece, surface treatment process, film thickness, etc.Coating Interval: Recoating interval: 1 hour for self-recoating, 2-8 hours for other coatings. Avoid moisture before the coating is fully dry. High zinc coatings can form zinc salts (white rust) on the surface; they should not be exposed for extended periods before applying the next coat. If zinc salts have formed, perform secondary removal treatment on the affected surface.Application Conditions: Environmental conditions: 0°C to 50°C, relative humidity during application less than 85%, no dust in the air.Preparation: Stir the contents in the bucket thoroughly from the bottom to ensure uniformity before use.Packaging Specification: 25KG/drumShelf Life: 12 months more>
