护坡塑料模具鉴定方法
外观鉴别
Appearance identification

通过观察的外观,可初步护坡塑料模具鉴别出护坡塑料模具制品所属大类:热塑性护坡塑料模具,热固性护坡塑料模具或弹性体护坡塑料模具。一般热塑性护坡塑料模具有结晶和无定形两类。结晶性塑料外观呈半透明,乳浊状或不透明,只有在薄膜状态呈透明状,硬度从柔软到角质。无定形一般为无色,在不加添加剂时为全透明,硬度从硬于角质橡胶状。热固性护坡塑料模具通常含有填且不透料明,如不含填料时为透明。弹性体具橡胶状手感,有一定的拉伸率。
Through the appearance of the observation, the plastic mould of the slope protection can be identified by the initial slope protection plastic mould, which belongs to the large category of the plastic mould products of the slope protection: the thermoplastic mould protecting slope, the thermosetting plastic mould for slope protection or the plastic mould of the elastic body. There are two types of plastic moulds for general thermoplastic revetment: crystallization and amorphous. Crystalline plastics are translucent, opaque or opaque in appearance, transparent only in the film state, hardness from soft to horny. Amorphous is generally colorless. It is completely transparent without additives and is hard from keratin to rubber. Thermosetting slope plastic moulds usually contain opaque materials and are transparent when they are free of filler. The elastomer has a rubber feel and has a certain tensile rate.

加热鉴别
Heating identification

上述三类护坡塑料模具的加热特征也是各不相同的,通过加热的方法可以鉴别。热塑性护坡塑料模具加热时软化,易熔融,且熔融时变得透明,常能从熔体拉出丝来,通常易于热合。热固性护坡塑料模具加热至材料化学分解前,保持其原有硬度不软化,尺寸较稳定,至分解温度炭化。弹性体加热时,直到化学分解温度前,不发生流动,至分解温度材料分解炭化。
The heating characteristics of the above three kinds of plastic moulds for slope protection are also different, which can be identified by heating. Thermoplastic moulds for slope protection soften when heated, are easy to melt, and become transparent when melted. They can often be drawn from the melt and are usually easy to heat up. Thermosetting slope protection plastic mold heated to the material before chemical decomposition, maintain its original hardness is not softened, the size is more stable, to decomposition temperature carbonization. When the elastomer is heated, it does not flow until the decomposition temperature, until decomposition temperature, material decomposition carbonization.
