Color printing woven bag is light in weight and good in abrasion resistance
May 26, 2023
The raw materials of color printing woven bags are composed of PP (polypropylene) and PE (polyethylene). The general characteristics of color printing woven bags are as follows:
1. Light weight
PP is usually relatively light, and the density of color printing woven bags is about 0.9-0.98 grams per cubic centimeter. Commonly used braids, if no filler is added, are equal to the density of plastic. Woven application plastics have a density of 0.9-0.91 g/cm3. Normally braid is lighter than water.
2. High breaking strength
Color printing woven bag is a kind of flexible material with high breaking strength in plastic products, which is related to its molecular structure, crystallization degree, draft orientation, etc., and also related to the type of additives. If specific strength (strength/specific gravity) To measure the plastic braid, it is higher than or close to the metal material.
3. Good chemical corrosion resistance
The color printing woven bag has good corrosion resistance to inorganic and organic matter, and it has no effect on it for a long time below 110 degrees Celsius. It has strong chemical stability to solvents, oils, etc. When the temperature rises, carbon tetrachloride, xylene, turpentine, etc. can swell it. Fuming nitric acid, fuming sulfuric acid, halogen elements and other strong oxides will oxidize it, and it has good corrosion resistance to strong alkali and common acids.
4. Good wear resistance
The coefficient of friction between color printing woven bags is small, only about 0.12, which is similar to that of nylon. To a certain extent, the friction between color printing woven bags and other items has a lubricating effect.
5. Good electrical insulation
Color printing woven bag is an excellent electrical insulator. Because it does not absorb moisture, is not affected by humidity in the air, and has a high breakdown voltage, its dielectric constant is 2.2-2.6, its volume resistance is very high, and its insulation is good, which does not mean that it is used for insulation material used.
6. Environmental resistance
At room temperature, the color printing woven bag is practically completely immune to moisture erosion. The water absorption rate within 24 hours is less than 0.01%, and the water vapor permeability is also very low. At low temperature, it becomes brittle and easy to crack.
7. Poor anti-aging ability
The aging resistance of color printing woven bags is poor, and its aging problems are mainly heat itching aging and photodegradation, which affect the service life and application fields of woven bags.
