13 Common types of waste plastics
Waste plastics refers to the general designation of plastics used and eventually eliminated or replaced in civil and industrial applications.
The types of waste plastics according to the different ways of reuse can be divided into:
1. Recycled plastic After the factory molding, extrusion, such as pre-processing, with scrap or unqualified mold products in two processing plants to process the preparation of thermoplastic plastic.
2. Re-processing of plastics by non-original processors, using discarded industrial plastics prepared thermoplastic.
3. Plastic recovered from discarded products washed and crushed.
4. Reusable plastic products can be reused many times, and performance to meet the requirements of the relevant provisions of plastic.
5. Recyclable plastics can be recycled after recycling, and after certain treatment, can be reused for a class of plastic.
6. Not recyclable plastic discarded, not allowed to be recycled and reused a class of plastic.
The types of waste plastics according to the specific chemical composition can be divided into: PE, PP, PVC, PET, EPS, PA, ABS
1.PET polyethylene terephthalate Two is also commonly known as polyester, a common Ubaut bottle. 2.HDPEPE is basically divided into three categories, high pressure low density polyethylene (LDPE), high-density polyethylene (HDPE) and linear low-density polyethylene (LLDPE).
HDPE high-density polyethylene is common in lotion container, milk bottle, supermarket plastic bag. 3.PVC PVC-For example: plumbing, curtains, credit cards, packaging, kettle, soft material film.
PVC PVC is common in pipe, outdoor furniture, raincoat. 4.LDPEPE is basically divided into three categories, high pressure low density polyethylene (LDPE), high-density polyethylene (HDPE) and linear low-density polyethylene (LLDPE). Mainly used in packaging, agriculture and transportation and other departments.
LDPE Low density polyethylene is common in the tube packaging of toothpaste or cleanser. 5.PP polypropylene polypropylene is common in bottle caps, straws, microwave oven food boxes.
Main uses: woven bags, waterproof cloth, consumer durables: such as automobiles, home appliances and carpets. 6.PS polystyrene is divided into no foaming or foaming. Not foaming namely Styrofoam, common in some drinks (such as beneficial force more) container, foaming is commonly known as Styrofoam, commonly used in packaging with plastic granules, disposable insulation cup, packaging frozen meat containers, lunch boxes.
Suitable for the fabrication of insulating transparent elements-decorative parts and chemical instruments-optical instruments and other components. 7. Other recyclable plastics include the use of methyl methacrylate (PMMA) Acrylic: Lighting apparatus, signboard advertisement, building windows and doors, compartment stair plate, daylighting wave board, Roof lighting cover, building decoration board, furniture, constant goods, electrical Machinery Industry Ministry products (Machine transparent cover, safety helmet, Optical aspects of the permeability, polycarbonate (PC), polylactic acid (PLA), nylon (Nylon) and FRP (FRP), modified polystyrene, plastic, high impact polystyrene (not brittle), general polystyrene, nylon polyamide, POM, sai Steel, plexiglass, sub-afterburner, polycarbonate-(bulletproof Adhesive)
biaxial tensile Polylactic acid film (BOPLA)
