In our common alarm product applications, such as urban integrated pipe gallery, petroleum and petrochemical, chemical, coal mines, etc., there are flammable and explosive safety hazards.
According to relevant research, there are about two-thirds of the underground coal mines with explosive substances. In the coal mine explosion-proof related regulations, the explosion-proof electrical equipment and small electrical appliances used in coal mines must have permanent explosion-proof signs (EXdI) and coal safety. Mark (MA), the operation, maintenance and repair of underground explosion-proof electrical equipment must meet the technical requirements of explosion-proof performance.
In the urban integrated pipe gallery, the safety hazard of the explosion mainly exists in the gas pipeline. The flammable substance of the gas pipeline is usually natural gas, the main component of which is methane, and also contains a small amount of ethane, butane, pentane, carbon dioxide and carbon monoxide. , hydrogen sulfide, etc. In GB50838-2015 "Technical Specifications for Urban Integrated Pipe Gallery Engineering", it is stipulated: "The electrical equipment in the natural gas pipeline compartment shall comply with the current national standard "Design Specification for Explosive Hazardous Environmental Power Equipment" GB50058 Explosion-proof Regulations for Zone 2 of Explosive Gas Environment" .
On the whole, in these common and important occasions, strict explosion-proof requirements are imposed on the corresponding products (such as monitoring, alarm, lighting, switch, etc.).
As an excellent alarm product and solution provider in the industry, Ai Li'an has also launched a series of explosion-proof alarm products for such special occasions. At present, Ai Li'an explosion-proof alarm products mainly include: explosion-proof, explosion-proof grating, explosion-proof Passive infrared detectors, etc., explosion-proof products have obtained explosion-proof certificate and test report.

HIGH CLASS SYNTHETIC WAX
PVC high-efficiency composite lubricant H108 is a multi-functional lubricant produced from several high-end raw materials. It has both internal and external lubrication functions, balances the lubrication in the front, middle and late stages, improves the degree of plasticization, increases physical properties, and improves the surface gloss of the product, decrease separate out phenomenon, improve the cycle of cleaning the mold. It is suitable for the production and processing of all PVC rigid products except transparent products, especially for high-filled products, such as drainage pipes, wall panels, SPC floors, etc.
Method of use and addition amount: replace all lubricants in the formula - stearic acid, paraffin wax, Fischer-Tropsch wax, Polyethylene Wax, stearate, etc. only add this one product to reduce the probability of mismatching. the amount of addition is 20%-25% lower than the total amount of all internal and external lubricants added in the original formula .
