Generally speaking, large plastic raw materials can be divided into two broad categories: "thermoplastic" (Thermoplastic), and "thermosetting plastic" (Thermosetting). At room temperature thermoplastic plastic usually granular, after heated to a certain temperature molten state, while its cooling after Curing, if it will become once again heating molten state, and the plastics can be re-forming. Therefore, thermoplastics can be repeated by heating and melting Curing, thermoplastic usually recyclable plastic waste reuse, which is the so-called "secondary material." On the contrary, thermosetting plastic is heated to a certain temperature curing after state, even if the heating can not continue to change its status. Therefore, the thermosetting plastic unable to repeatedly by reheating molding, thermosetting plastic waste recycling usually is not used. 阿拉伯文到英语朝鲜语到英语德语到法语德语到英语俄语到英语法语到德语法语到英语荷兰语到英语葡萄牙语到英语日语到英语西班牙语到英语希腊语到英语意大利语到英语英语到阿拉伯文英语到朝鲜语英语到德语英语到俄语英语到法语英语到荷兰语英语到葡萄牙语英语到日语英语到西班牙语英语到希腊语英语到意大利语英语到中文(繁体)英语到中文(简体)中文到英语中文(繁体到简体)中文(简体到繁体)

Generally speaking, the plastic raw material may greatly divide intotwo big kinds: "Thermoplastic" (Thermoplastic) and "thermosettingplastics" (Thermosetting). Thermoplastic under normal temperatureusually for granulated, heats up condition which turns after thecertain temperature fuses, after solidifies its cooling takes shape,if heats up once more then can turn the condition which fuses, but maycarry on the once more plasticizing to take shape. Therefore, thethermoplastic may by way of heat up fuses but repeatedly solidifiestakes shape, therefore the thermoplastic waste material usually mayrecycle uses again, that is so-called has "two materials". Opposite,the thermosetting plastics is heats up after the certain temperatureturns the solidification condition, even if continues to heat up alsois unable to change its condition. Therefore, the thermosettingplastics is unable by way of to heat up again repeatedly takes shape,therefore the thermosetting plastics waste material usually is cannotrecycle the again use.

一般而言,塑料原料可大分为两大类:「热塑性塑料」(Thermoplastic)及「热固性塑料」 (Thermosetting)。热塑性塑料在常温下通常为颗粒状,加热到一定温度后变成熔融的状态,将其冷却后则固化成型,若再次加热则又会变成熔融的状态,而可进行再次的塑化成型。因此,热塑性塑料可经由加热熔融而反复固化成型,所以热塑性塑料的废料通常可回收再利用,亦即有所谓的「二次料」。相反的,热固性塑料则是加热到一定温度后变成固化状态,即使继续加热也无法改变其状态。因此,热固性塑料无法经由再加热来反复成型,所以热固性塑料的废料通常是不可回收再利用的。 Generally speaking, plastic materials can be divided into two broad categories: "thermoplastic" , and "thermosetting plastic" . Thermoplastic plastic usually get granular at normal temperature , after heated to a certain temperature molten state, while its cooling after Curing, if it will become once again heating molten state, and the plastics can be re-forming. Therefore, thermoplastics can be repeated by heating and melting Curing, thermoplastic usually recyclable plastic waste reuse, which is the so-called "secondary material." On the contrary, thermosetting plastic is heated to a certain temperature curing after state, even if the heating can not continue to change its status. Therefore, the thermosetting plastic unable to repeatedly by reheating molding, thermosetting plastic waste recycling usually is not used.楼上的都是翻译软件搞出来的,不准确
