What are the uses of mineral water bottles obtained after being crushed by a plastic crusher? Which industries are mainly used in? For the convenience of customers' production experience, Henan Fukai Machinery will explain this for you. Mineral water bottles are mainly made of polyethylene terephthalate, also known as PET. For this type of waste plastics, mineral water bottles and beverage bottles are usually used as guarantee materials in the food industry, and after one-time use This type of plastic is crushed and processed by a plastic crusher, cleaned and dried to make PET flakes, which are used in chemical, construction and other industries. According to their application, the crushed flakes are mainly used for the following purposes:
1. Re-manufacture PET bottles. Recycled pellets cannot be used in direct contact with food, but can be used in the middle layer of three-layer PET bottles to make carbonated beverage bottles.
2. Spinning to make fibers. Recycled PET materials can be used to spin into fibers for pillow cores, mattresses, sleeping bags, felts, etc.
3. Glass fiber reinforced material. Recycled PET reinforced by glass fiber has good heat resistance and mechanical strength. It can be used to make auto parts, such as heat-resistant car wheel covers, and its thermal distortion temperature can reach 240 degrees. Flexural modulus of 9500MPa, bending strength of 214 MPa, impact strength of 15kf/m2.d. Blending modification, recycled PET material can be blended with other polymers to prepare various modified materials, such as blending with PE , Can obtain PET blends with improved impact performance, PE: PET is (10-50): (90-50): If a small amount of polypropylene is added, the dimensional stability of the blend can be significantly improved. Because the polarity of PE and PET is quite different, it is necessary to carry out compatibility treatment during blending. Generally, the compatibility is improved by grafting modification of polyolefin.
4. Alcoholysis, PET waste is alcoholyzed in the presence of a basic catalyst, and then polycondensation such as dibasic acid anhydride is added to obtain a product with an acid value greater than 12, which is diluted, filtered, and an appropriate amount of catalyst is added to obtain alkyd resin paint.
Through the above introduction, the existing plastic bottles are mainly divided into the above-mentioned uses according to the plastic use level after being crushed. In the selection of equipment, the waste beverage bottle can be processed by the plastic crusher supporting the de-labeling machine, the cleaning production line, and the spin dryer to form recycled PET The crushing production line is used for crushing and processing waste plastics such as mineral water bottles and beverage bottles recovered in the market to obtain considerable economic value.
