Liaoning transparent plastic packaging bottle processor which large production enterprises. MGG purchase high quality PET plastic packaging bottle, transparent plastic packaging bottle is looking for us, our company is a leader of the industry, quality assurance, worthy of trust. Polyethylene terephthalate The diol ester is the most important variety in the thermoplastic polyester, and the English name is Polythylene Terephthalate referred to as PET or PETP (hereinafter or called PET), commonly known as polyester resin. It is a polycondensate of terephthalic acid with ethylene glycol, which is collectively referred to as a thermoplastic polyester together with PBT, or a saturated polyester. PET is a milky white or a front yellow highly crystalline polymer, and the surface is smooth and lustrous.
Wheat resistance, fatigue resistance, friction and size stability, high wear, high hardness, high toughness in thermoplastic; good electrical insulation performance, low temperature effect, but poor resistance is poor. Non-toxic, weather resistance, good chemical, low water absorption, low acid and organic solvent. The physical recovery treatment method of the PET plastic bottle is relatively simple, mainly to clean the clean PET plastic bottle of waste and granulation.
The physical treatment method of the PET plastic bottle is closely related to the sorting process. There are two physical recovery methods: First, the waste PET plastic bottle is subjected to a film, from the PET from the PET to the HDPE, aluminum, paper and adhesive, PET fragments, washed, dry, granulated; second, first Waste PET plastic bottles are not PET bottle cap, the bottom, label and other impurities are separated by mechanical methods, and then washed, broken, granulated. PVC impurities must not contain PVC impurities in the regeneration PET, otherwise the color of PET will be affected.
When the amount of PVC is less in the conveyor, it can be separated from the conveyor, that is, the PVC and PET plastic bottles produce different different melting points in the force part, and the PET and PVC fragments are equipped with heaters and temperatures. The controlled conveyor belt, the PVC is adhered to the conveyor belt after being melted, which can be separated from the PET.
