Nozzles: 20 nozzles per meter, multi-angle embedded adjustable mirror-polished stainless steel nozzles, with a face 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 on an internal circulation system: air generated by the high-pressure centrifugal fan in the fan box enters the air plenum, is filtered through a 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 vent.4. Filters: The air shower is equipped with 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, with two 0.75KW high-pressure centrifugal fans per meter, ensuring effective blowing. Parameters of the centrifugal fan 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 personnel are 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 turning off for 60 seconds after the air shower completes.8. Circuit control: The air shower control panel and control circuit are designed and developed in-house, featuring advanced high-tech integrated circuit control with photoelectric sensors. The text display shows internal blowing, lighting display, and time adjustment buttons. The air shower time is adjustable from 0 to 99 seconds. An LED display shows the 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, it automatically senses and initiates blowing (entering from the exit 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>

Company: Suzhou Century Xing Industrial Technology Co., Ltd.

Product Description: A flameless venting device is a safety apparatus used to protect equipment and personnel. It automatically shuts down equipment or pipelines in the event of an explosion or fire, preventing the spread of flames or the escalation of an explosion. Its working principle involves detecting changes in gas pressure and temperature inside pipelines or equipment to determine whether there is a risk of explosion or fire. If a hazard is confirmed, it immediately shuts down the equipment or pipeline while releasing pressure to achieve the goal of protecting both equipment and personnel.Dust Explosion Relief Valve for Dust Collector Pipelines (Flameless Venting Device)Brief Introduction:1. It consists of two parts: a venting panel and a flame extinguishing module;2. Suitable for flameless venting of dust explosions in indoor equipment. It offers high venting efficiency and is cost-effective;3. Effectively prevents flames and heat, providing a safe environment for equipment, buildings, and personnel. It also collects dust effectively, reducing environmental pollution;4. When used in combination with an isolation valve, it not only prevents pressure waves and flames from propagating to upstream workshop areas but also suppresses secondary explosions, reducing property damage and ensuring personnel safety.Product Parameters:Static opening pressure: 0.01 MPa;Frame material: Carbon steel or stainless steel;Flame-retardant material: 304SS;Applicable dust: St1 and St2 dust with Kst ≤ 300 barg*m/s, with effective venting area meeting explosion relief requirements;Product classification: Depending on the working conditions, it can be divided into rectangular flameless venting devices and curved flameless venting devices;Applicable equipment: Dust collectors, bucket elevators, drying equipment, cyclone separators, dust collectors;Industries: Wood processing, plastics, spraying, food and dairy, plastic and dye processing, grain storage and processing, pharmaceuticals, coal processing, brewing, chemicals, metal processing, chemicals, power, cement, and other industries.Dust Explosion Relief Valve for Dust Collector Pipelines (Flameless Venting Device)Working Principle:The flameless venting device consists of two parts—an explosion-proof panel and a fire extinguishing module. The explosion-proof panel responds to the rapid increase in deflagration pressure, immediately opening to reduce pressure. When the expanding fireball passes through the open explosion-proof panel, it is intercepted by the fire extinguishing module. The precision stainless steel mesh supported by the frame acts as a three-dimensional flame trap, extinguishing the flame and ensuring it does not propagate, thereby preventing secondary or multiple explosions. The fire extinguishing module eliminates deflagration flames, reduces the temperature of hot gases, and captures both burning and unburned dust passing through the open explosion-proof panel.At the same time, pressure waves or noise generated by production equipment are also minimized. As flames pass through the mesh flame-retardant element, heat exchange occurs between the element and the flame, rapidly cooling the high-temperature flame, releasing pressure and smoke. Additionally, pressure waves or noise generated by production equipment are reduced.Application Areas:Widely used in industries such as grain, metallurgy, chemicals, power, light industry, tobacco, pharmaceuticals, mechanical processing, and solid waste treatment. Applicable equipment includes cyclone separators, bag dust collectors, dust collectors, cartridge filters, pneumatic conveying systems, rod or ball mills, bucket elevators, dryers and ovens, roller mills, and buildings.With increasingly stringent environmental inspections, safety is gaining more attention. In the past, venting panels were commonly installed on dust collectors to release overpressure caused by dust explosions. However, installing such devices indoors is not permitted by safety regulations, as it poses risks to surrounding personnel and equipment. The pressure waves and flames from explosions may cause secondary or multiple explosions, creating hazards. Therefore, relying solely on explosion-proof panels for dust collectors is unreliable. We recommend using flameless venting + isolation technology (a more economical solution) or explosion suppression + isolation technology to ensure production safety.There are three main methods for dust explosion protection: venting, isolation, and suppression.Venting: Releases explosion pressure in advance through a pressure relief device to protect equipment from damage.Isolation: Blocks explosions using an isolation valve to prevent flame propagation.Suppression: Detects sparks using detection devices, then activates fire extinguishing systems to instantly extinguish flames and prevent explosions. more>

Product Description: Specializing in manufacturing pollution-free crushing equipment, innovative design, unique technology, and superior manufacturing, the GTJ fluidized bed jet mill and its automated production line are one of the typical models of pollution-free ultrafine grinding. The lining, classification wheel, and nozzles are all made of engineering ceramics.    I. Main Structure:    The machine mainly consists of: 1. Upper and lower body; 2. Classification system; 3. Air ring; 4. Crushing system; 5. Pressure display system; 6. Feeding system; 7. Discharge system and machine base.    II. Working Principle:    The crushing principle utilizes fluid dynamics from aerospace technology, designing several supersonic nozzles assembled on the circumference of the crushing zone. When purified compressed air is accelerated through the nozzles, it carries the material to be crushed, added by the feeding system, and directly impacts materials coming from the opposite direction via the same principle. This forms multiple nozzles (or guns) focusing on the same point, causing the material to be crushed through shearing, impact, and friction.    The crushed material is carried by the rising airflow to the classification zone. Through the high-speed rotating classification wheel, qualified powder is separated by centrifugal force and sent with the airflow to the cyclone (also known as the gas-solid separator) for collection. A small amount of ultrafine powder continues with the airflow into the collector (also known as the dust collector), where the gas is discharged and the powder is filtered out.    III. Features:1. The crushing mode involves direct impact between materials, resulting in high impact force utilization.2. Equipped with an independent ceramic classification wheel. Through variable frequency speed regulation, the particle size range can be adjusted arbitrarily to meet the required particle size distribution for various materials, resulting in a narrow particle size distribution range.3. Suitable for ultrafine grinding of brittle materials with a hardness below level 7.4. The crushing process mainly involves collisions between materials, with minimal contact with the inner wall of the crushing zone, resulting in very low wear. The lining is entirely made of engineering ceramics, ensuring the product remains uncontaminated.5. The machine has a relatively simple structure and is easy to operate. Apart from the ceramic parts, the entire machine is made of SUS304 stainless steel (with polishing or matte finishing).    Application Scope:    Suitable for high-tech ceramic materials, lithium battery cathode and anode materials, trichromatic phosphors, LED and other luminescent materials, electronic materials, copy powders, fine chemical materials, and other ultrafine powder industries. It can form an automated production line, achieving integrated mechanical-electrical systems and dust-free ultrafine powder processing. more>

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>
