Identification Method of Plastic Mould for Slope Protection
By observing the appearance, we can identify the main types of plastic moulds for slope protection: thermoplastic moulds for slope protection, thermosetting moulds for slope protection or elastomeric moulds for slope protection. Generally, there are two types of thermoplastic moulds for slope protection: crystalline and amorphous. Crystalline plastics are translucent, opaque or opaque in appearance, only transparent in the film state, with hardness ranging from soft to horny. Amorphous is generally colorless, transparent without additives, harder than keratinous rubber. Thermosetting plastic moulds for slope protection usually contain fillings and are opaque, such as transparent without fillers. The elastomer has a rubber handle and a certain tensile strength.
The heating characteristics of the above three types of slope protection plastic moulds are also different, which can be identified by heating method. Thermoplastic moulds for slope protection soften and melt easily when heated, and become transparent when melted. Wires are often drawn from the melt, which is usually easy to heat. Thermosetting slope protection plastic mold is heated until the material is chemically decomposed. Its original hardness is not softened, and its size is stable until the decomposition temperature is carbonized. When the elastomer is heated, no flow occurs until the decomposition temperature, and the material is decomposed and carbonized at the decomposition temperature.
