Plastic woven bags are very common in life and we need them everywhere. The appearance of its composite bags can be said to provide a lot of convenience for our lives, but do you know what properties the plastic woven bags have during use? !
Plastic woven bags have the characteristics of light weight, good electrical insulation, good corrosion resistance and non-corrosive color non-woven bags, easy processing and forming. Plastic woven bags have some common characteristics of pp and its own characteristics.
1. Lightweight: pp is usually lighter, and the density of pp woven bags is about 0.9-0.98 g / cm3. Commonly used plastic braid, if no filler is added, it is equal to the density of plastic. For plastic weaving applications, the density of plastic is 0.9-0.91 g / cm3. In general, plastic woven bags are lighter than water in the case of woven bags.
2. High breaking strength: Plastic braid is a kind of flexible material with high breaking strength in plastic products. This is related to its molecular structure, crystallinity, drawing orientation, etc., as well as the type of additives. Strength (strength / specific gravity) is a measure of plastic braid, which is higher or close to metal materials.
3. Good chemical resistance: plastic braid has good corrosion resistance to inorganic and organic substances, below 110 degrees Celsius, it has no effect on it for a long time, it has strong chemical stability to solvents, grease, etc. Sex. When the temperature rises, carbon tetrachloride, xylene, turpentine, etc. can swell. Fuming nitric acid, fuming sulfuric acid, halogen elements and other strong oxides will oxidize it. It has good corrosion resistance to strong bases and general acids.
4. Good wear resistance: the friction coefficient between pure plastic braid is small, only about 0.12, similar to nylon. To a certain extent, the friction between plastic braid and other items has a lubricating effect.
5. Good electrical insulation: pure plastic braid is an excellent electrical insulator. Because it does not absorb moisture, it is not affected by moisture in the air, and its breakdown voltage is also high. Its dielectric constant is 2.2-2. 6. Its volume resistance is very high, and the insulation of the plastic braid is not good. It is equivalent to using it as an insulating material.
6. Environmental resistance: At normal temperature, the plastic woven cloth is actually completely free of water erosion. The water absorption within 24 hours is less than 0.01%, and the water vapor permeability is also very low. At low temperatures, it becomes brittle. Easy to crack. Plastic braid will not mold.
The use of plastic woven bags and their own properties make it widely used by everyone, so it is extremely widely used in the field of application, but because plastics are not easily degradable products, so remind everyone to use the environment during recycling to protect the environment health.
