| 护坡塑料模具鉴定方法 Identification method of plastic mould for slope protection 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. The appearance of crystalline plastics is translucent, opaque or opaque, only transparent in the film state, from hardness to keratin. 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. |
