The quality of the product is directly related to the choice of raw materials. The quality of the raw materials depends on the quality of the raw materials and the amount of raw materials added. Therefore, when manufacturing any kind of product, you need to be cautious in the selection of raw materials. Grasp. What kind of manufacturers have a lot of demand for FIBCs during production, so what should be the selection criteria for FIBC raw materials, and how can they make FIBCs with high pressure? I want to share with you here, let’s take a look.
The main raw materials for the production of container bags include polypropylene, calcium carbonate, and anti-aging agents, which are characterized in that the anti-aging agents are: 3,5-dimethoxy-4-hydroxybenzoic acid, 3,5-dimethoxy- 4-hydroxybenzoic acid accounts for 1-5% of the total weight of polypropylene. Calcium carbonate accounts for 5-10% of the total weight of polypropylene, and 3,5-dimethoxy-4-hydroxybenzoic acid is added with an ultraviolet absorber. The ultraviolet absorber is o-hydroxy benzophenone. These raw materials are used to make bulk bags. After aging tests, the retention rate of tensile strength at break of warp threads is 70-75%, and the retention rate of tensile strength at break of weft threads is 55-60%. When the FIBC is made, when the calcium carbonate is added at 5-10% of the weight of the polypropylene, the anti-aging performance is good and it can be used as the raw material for FIBC production. And it should be noted that the FIBC cannot be exposed to the sun for a long time when in use, so as not to cause the tensile strength of the FIBC polypropylene to continuously decrease.
For FIBC manufacturers, only by producing good quality FIBC products can they enhance their market competitiveness. The use of raw materials and processing procedures when making FIBCs are not sloppy. Only the FIBC produced will be qualified. Now everyone should have a clear understanding of the raw materials of the FIBC. I hope this article can help you.
