What are the commonly used heat stabilizers in the production of flame retardant and fireproof tarpaulins?

There will inevitably be some small problems in the production process of flame retardant and fireproof tarpaulin manufacturers. Let's take a detailed look at how to identify flame retardant and fireproof tarpaulins. At first, look at the appearance, the color is bright and consistent, and then you can scrape it with your hand to see if the plastic-coated glue does not fall off. If it does, it is definitely not a good cloth. The thickness of the glue should be moderate. If it is too thick, it will not be easy to handle. If it is too light and thin, the service life will not work. Then touch the softness of the flame retardant and fireproof tarpaulin by hand. Generally speaking, the softer the better. If the flame retardant fireproof tarpaulin has a special purpose, look at the flame retardant degree and see how long the fire can be extinguished on it. Of course, the shorter the time, the better. When judging the strength, you can try to tear it by hand, the greater the strength, the better. In addition, it is also necessary to check whether there are any flaws on the flame retardant and fireproof tarpaulin, and there are often problems such as water leakage and rupture in the flawed places. When we use flame retardant fireproof tarpaulin, keep it dry. After use, hang up the flame retardant and fireproof tarpaulin to air dry. If it is found that the flame retardant and fireproof tarpaulin is dirty, it should be gently brushed with water, and chemically added detergents should not be used, and do not scrub hard to prevent damage to the waterproof film on the surface of the fabric and affect the waterproof function of the tarpaulin. The main material of fire retardant tarpaulin is plastic. However, when this material is used, some additives are usually added to enhance its properties. Heat stabilizers are one of them. It is mainly used to prevent plastics from being heated. Degradation occurs. What are the commonly used heat stabilizers in the production of flame retardant and fire retardant tarpaulins? (1) Organotin: These heat stabilizers are mainly used in various soft PVC products that require transparency. Commonly used varieties are maleates, thiolates and carboxylates. Among them, di-n-octyl tin maleate, S, S'-bis(iso-octyl thioglycolate) di-n-octyl tin can be used as cleaning stabilizer for food and pharmaceutical packaging materials. (2) Alloy metal salt: the most common type of heat stabilizer. It is usually sold as a pre-formed liquid, paste or powder. Commonly used varieties are barium-cadmium, barium-calcium-zinc, barium-zinc, calcium-zinc and calcium-magnesium-tin-zinc professional fatty acid salts. Such thermal stabilizers are often used in combination with organic adjuvants such as phosphites, epoxies, polyols and phenolic chemical inhibitors to form composite thermal stabilizers that meet the requirements of different processing technologies and product applications. (3) Special heat stabilizer: refers to some organic compounds with special effects, such asα- Phenylhydrazine, aminocrotonate used in alkaline emulsion polymerized polyvinyl chloride, pentaerythritol or dicyandiamide used in asbestos filled PVC flooring materials. (4) Lead salt: one of the early applications of heat stabilizers. It has excellent long-term thermal stability, weather resistance and electrical insulation, but it affects the transparency of the product, is toxic, has initial coloration, is easy to vulcanize, and has poor compatibility and dispersion with PVC. Lead salts do not lubricate and should be used in combination with metal soap lubricants. Commonly used varieties are ternary lead sulfate and dibasic lead phosphite. For the manufacture of opaque PVC sheets, pipes and wire and cable jackets. When using flame retardant and fireproof tarpaulin, there is also a difference in quality. Although some products can meet the ordinary use requirements, some problems are prone to occur when the flame retardant and fireproof tarpaulin is used. One is water seepage. , The general flame retardant and fireproof tarpaulin can also achieve the purpose of blocking water, but it often cannot achieve water seepage when it blocks water. Now there are many products with insufficient quality, which often appear water seepage during use. phenomenon, and this phenomenon often has a corresponding impact on the items to be protected in the middle, so attention should be paid to this issue. Another is that it has poor wind resistance. Although this product has to achieve a good waterproof purpose at first, when it is used, it is often applied outdoors or on vehicles, so it also has to achieve corresponding resistance to wind. , Of course, whether it is water seepage or poor wind resistance, it is also closely related to the production process and materials of flame retardant and fireproof tarpaulins. Before using the tarpaulin field shelter, it is necessary to carefully survey the terrain, and there should be no rolling stones, logs and those weathered rocks above the camp; one of the main tent materials provided by flame retardant and fireproof tarpaulin manufacturers, the main functions are moisture-proof, waterproof and wind-resistant. , dustproof, anti-sunshine, etc. Its application areas include emergency rescue and disaster relief, short-term field operations, etc. Due to its house-like shape, the tarpaulin dwelling feels very homely. Its products have high rigidity, strong stability, strong wind resistance, can stand for a long time after molding, and are also very fast in recycling, which is suitable for field operations in various environments such as emergency rescue and disaster relief.
