What are the uses of plastic powder


Plastic powder, plastic superfine powder, resin powder Plastic is a synthetic polymer compound polymer, also known as macromolecules or macromolecules (macromolecules), also commonly known as plastics resins, you can freely change the body style. It is a material synthesized by using monomer raw materials for synthesis or condensation reaction. It is composed of synthetic resins and fillers, plasticizers, stabilizers, lubricants, colorants and other additives.

Plastics are roughly divided into two types: thermoplastic and thermoset. Thermoplastic is that the material will soften after heating, and will harden into the shape we need after cooling, and can be softened repeatedly. The thermosetting type will condense into a certain shape after heating, and reheating to a certain degree will destroy the internal structure of the molecule, releasing one or more of the elements that will detach and become other composites.

Main features of plastic powder:

Strong plasticity: Plastic powder can be shaped into various shapes by heating, pressing, etc., which gives it great advantages in manufacturing products of various complex shapes.
Good stability: Plastic powder has good stability at room temperature, is not easily affected by the external environment, and can maintain the stability of its physical and chemical properties.
Corrosion resistance: Plastic powder has good corrosion resistance to many chemicals and can be used in various harsh environments.
Environmental protection: With the advancement of technology, more and more environmentally friendly plastic powders have been developed, which have less impact on the environment during production and use.

Common uses of plastic powder:

Automobile manufacturing: In automobile manufacturing, plastic powder is widely used to manufacture various parts, such as dashboards, seats, door guards, etc.Auto parts made using plastic powder are not only lightweight, but also have good corrosion resistance and stability, helping to improve the fuel efficiency and performance of the car.
Packaging industry: Plastic powder is also widely used in the packaging industry.It can be processed into various plastic films, plastic bags and other packaging materials, and used for packaging of food, daily necessities, cosmetics, etc.These packaging materials not only have good moisture-proof, dust-proof, and drop-proof properties, but are also environmentally friendly and biodegradable, which is in line with the development trend of the modern packaging industry.
Construction industry: In the construction field, plastic powder can be used to produce various plastic sheets, pipes, insulation materials, etc.These materials are not only lightweight and easy to install, but also have excellent weather resistance, corrosion resistance and fire resistance, helping to improve the comfort and safety of the building.
Electronic and electrical appliances: In the field of electronic and electrical appliances, plastic powder is used to manufacture various insulation materials, casings and parts.Its high insulation properties and good processing properties make electronic and electrical products safer and more reliable.
Daily necessities: Plastic powder can also be used to make various daily necessities, such as plastic buckets, plastic basins, plastic tableware, etc.These products are lightweight, durable and affordable, making them popular among consumers.

The powder fineness is generally expressed by the mesh number. A mesh number is a unit of length and the size of the sieve mesh diameter. It represents the number of aliquots within one inch, but the diameter of the mesh wire needs to be deducted.
1 micron ———- 12500 mesh
1.3 micron ——– 8000 mesh
2 microns ———- 6250 mesh
2.6 microns ——– 5000 mesh
5 microns ———- 2500 mesh
6.5 microns ——– 2000 mesh
10 micron ——— 1250 mesh
15 microns ——— 800 mesh
20 microns ——— 625 mesh
33 microns ——— 425 mesh
37 microns ——— 400 mesh
44 microns ——— 325 mesh
74 microns ——— 200 mesh
149 microns ——– 100 mesh
350 microns ——– 45 mesh

The use of coarse powder, medium powder, fine powder and superfine powder is in different requirements. In plastic powder particles, coarse powder refers to powder with a size of 5 to 60 mesh, and medium powder refers to powder with a size of 60 to 160 mesh. Fine powder 160 to 300 mesh, more than 300 mesh belongs to ultrafine powder. But according to the degree of easy crushing of different raw materials, the classification of coarse, medium, fine and ultra-fine is different. For some compounds such as calcium carbonate, 300 mesh can only be regarded as coarse powder.
