Problems solved by technology

[0003] However, the existing technology represented by the above-mentioned patent documents still has the following defects in the actual use process: 1. The main characteristics of this patent are flame-retardant and anti-static, and it is a single-layer structure, with tensile strength, peeling force, Compared with the packaging of hazardous chemicals such as drop resistance and heat resistance, its physical properties are still low, and it is not suitable for plastic packaging of hazardous chemicals (including export); 2. The woven bag cannot use waste plastic bottles Or silk (cloth) to manufacture, there are disadvantages of high energy consumption, expensive and not conducive to environmental protection
3. The patent uses metal materials and biomass materials, which are relatively expensive, and the production process is complicated and the production cycle is long, which is not conducive to market competition

Abstract

The invention discloses a method for manufacturing a plastic package for a hazardous chemical substance. The method is characterized by comprising the following steps: pretreatment of raw materials, dosing and mixing, wire unreeling, wire reeling, weaving, compounding, cutting, sewing, film covering and performance detection. By the method, waste plastic packages can be recycled to serve as raw materials, so as to obviously reduce energy consumption and shorten processing cycle. The physical performance of the plastic package manufactured by the method is over 30 percent better than that of the GB / TB947-1998 standard, so as to ensure the safety of the package of the hazardous chemical substance and meet the requirement of the plastic package of the hazardous chemical substance (comprising export).

Description

technical field [0001] The invention relates to a method for manufacturing plastic packaging, in particular to a method for manufacturing plastic packaging for hazardous chemicals. Background technique [0002] According to the different types of dangerous goods, hazardous chemicals are packaged in different ways. Common ones include metal packaging, glass ceramic packaging, cotton and linen fabric packaging, and plastic woven material packaging. Among them, plastic woven material packaging mainly uses ingredients, drawing, and weaving. Made by other processes, its physical properties are usually: tensile load of cloth N / 50㎜, radial direction ≧ 450, weft direction ≧ 450, bonding direction ≧ 300, seam side direction ≧ 250, seam bottom direction ≧ 200, peeling The force N / 30㎜ is not less than 2.5-3, which meets the national GB / T8947-1998 standard. For example, China Patent No. "201010252205.0" discloses a manufacturing method for composite packaging bags. The disclosure date i...
