塑胶原料的概念

The concept of plastic raw materials

1. 塑胶原料的主要成份是树脂

1. the main component of plastic material is resin.

2塑胶原料:是由高分子合成树脂(聚合物)为主要成份渗入各种辅助料或添加剂,在特定温度,压力下具有可塑性和流动性,可被模塑成一定形状,且在一定条件下保持形状不变的材料.

2 Plastic raw material: It is a kind of material which is made up of polymer synthetic resin (polymer) and infiltrated into various auxiliary materials or additives. It has plasticity and fluidity under certain temperature and pressure. It can be molded into a certain shape and keep the shape unchanged under certain conditions.

3. 聚合物:指聚合过程所产生的纯材料或称聚合材料.无论天然树脂还是合成树脂均属高分子合聚物,简称高聚物.

3. Polymer: refers to the pure material or polymeric material produced during the polymerization process. Both natural and synthetic resins are polymeric polymers, referred to as polymers.

4.塑胶对电,热,声具有良好绝缘性:电绝缘性,耐电弧性,保温,隔声,吸音,吸振,消声性能卓越.

4. Plastic has good insulation for electricity, heat and sound: electrical insulation, arc resistance, heat preservation, sound insulation, sound absorption, vibration absorption, noise elimination performance is excellent.

塑胶原材料大部是从一些油类中提炼出来的,最熟悉的部分PC料是从石油中提炼出来的, PC料在烧的时候有一股汽油味;ABS是从煤炭中提炼出来的, ABS在烧完灭掉的时候会呈烟灰状;POM是从天然气提炼出来的, POM在烧完的时候会有一股非常臭的瓦斯味．

Most of the plastic raw materials are extracted from some oils, the most familiar part of the PC material is extracted from petroleum, PC material has a gasoline smell when burning; ABS is extracted from coal, ABS will be sooty when burned out; POM is extracted from natural gas, POM will have a puff when burned out. A very smelly smell of gas.

一般塑胶原料的特点

Characteristics of general plastic raw materials

a. 塑胶原料受热膨胀,线胀系数比金属大很多;

A. plastic material is heated and expanded, and the coefficient of linear expansion is much larger than that of metal.

b.一般塑胶原料的刚度比金属低一数量级;

B. generally, the rigidity of plastic raw materials is lower than that of metals by an order of magnitude.

c. 塑胶原料的力学性能在长时间受热下会明显下降;

The mechanical properties of C. plastic materials will decrease significantly under prolonged heat.

d.一般塑胶原料在常温下和低于其屈服强度的应力下长期受力,会出现永久形变;

D. Permanent deformation occurs when plastics are subjected to long-term stress at room temperature and below yield strength.

e. 塑胶原料对缺口损坏很敏感;

E. plastic material is sensitive to notch damage.

f. 塑胶原料的力学性能通常比金属低的多,但有的复合材料的比强度和比模量高于金属,如果制品设计合理,会更能发挥起优越性;

F. The mechanical properties of plastic materials are usually much lower than those of metals, but some composite materials have higher specific strength and modulus than metals. If the product design is reasonable, it will play a more superior role.

g.一般增强塑胶原材料力学性能是各项异性的;

G. generally enhance the mechanical properties of plastic raw materials are heterosexual.

h.有些塑胶原料会吸湿,并引起尺寸和性能变化;

H. some plastic materials can absorb moisture and cause changes in size and performance.
