Xi'an plastic bucket manufacturer Take everyone Judging from the advantages and disadvantages of plastic properties

Shaanxi plastic bucket manufacturer -Easy to process and manufacture (easy to form)

Even if the geometric shape of the product is very complex, as long as it can be demoulded from the mold, it is also easier to manufacture. Therefore, its efficiency is far better than metal processing, especially injection molding products. After a process, very complex finished products can be produced.

It can be colored or made into transparent products as required

Plastic can be used to make colorful, transparent and beautiful products, or it can be colored at will to improve its commodity value and give people a bright feeling.

It can produce light and high strength products. Compared with metal and ceramic products, it has the characteristics of light weight, good mechanical properties and high specific strength (high density ratio). It can produce light and high strength products. In particular, the strength can be improved after glass fiber is filled.

In addition, because of its light weight and energy saving, its products are becoming lighter and lighter.

No rust and corrosion

Plastics are usually resistant to various chemicals and are not as easy to rust or corrode as metals. Don't worry about acid, alkali, salt, oil, medicine, humidity and mold erosion.

Not easy to heat transfer, good thermal insulation performance

Because of its high specific heat, low thermal conductivity and difficult heat transfer, plastics have good thermal insulation effect. It can make conductive parts and insulating products

Plastic itself is a good insulating material. At present, it can be said that no electrical products do not use plastic. However, if the plastic is filled with metal powder or chips for molding, it can also be made into products with good conductivity.

Excellent shock absorption and noise elimination performance and good light transmittance

Plastics have excellent shock absorption and noise elimination performance; Transparent plastics (such as PMMA, PS, PC, etc.) can be made into transparent plastic products (such as lenses, signs, covers, etc.).

Low product manufacturing cost

Although the plastic raw material itself is not cheap, because the plastic is easy to process and the equipment cost is relatively low, the product cost can be reduced.

Advantages and disadvantages of plastic properties

Disadvantages of plastics

Poor heat resistance, easy to burn

This is a disadvantage of plastics. Compared with metal and glass products, its heat resistance is much worse. If the temperature is slightly higher, it will deform and burn easily. Most plastics will produce a lot of heat, smoke and toxic gases when burning; When the temperature exceeds 200 ℃, even thermosetting resins will smoke and fall off.

With the change of temperature, the properties of materials will change greatly

Needless to say, even at low temperatures, various properties will change greatly.

Low mechanical strength

Compared with metal of the same volume, its mechanical strength is much lower, especially for thin products.

Easily corroded by special solvents and drugs

Generally speaking, plastics are not easily corroded by chemicals, but some plastics (such as PC, ABS, PS, etc.) have poor performance in this respect; In general, thermosetting resins have strong corrosion resistance.

Poor durability and easy aging

It is not durable in strength, surface gloss or transparency, and has creep under load. In addition, all plastics are afraid of ultraviolet rays and sunlight, and will age under the action of light, oxygen, heat, water and atmospheric environment.

Vulnerable to damage, dust and dirt

The plastic surface has low hardness and is easy to be damaged; In addition, because it is an insulator, it has static electricity, so it is easy to be polluted by dust.

Poor dimensional stability

Compared with metal, Xi'an plastic bucket The plastic shrinkage rate of is very high, so it is difficult to ensure the dimensional accuracy. If moisture, moisture absorption or temperature changes during use, the size can easily change over time.
