Plastic simple identification method
In the u of various plastic recycling methods for the reu of waste plastics, most of the need to sort the plastic. As plastic consumption channels are many and complex, some of the plastic after consumption is difficult to distinguish by simple appearance, so it is better to mark material varieties on plastic products. China according to American Association of plastic material (SPE) is propod and the implementation of the development of cultivars GB/T16288 - 1996 "plastic packaging products recycling, methods can u the tag to facilitate sorting, but becau there are many China unmarked plastic products, bring difficulties to the sorting, for different varieties of plastic respectively, so that paration and recovery, we must first master the identification of different knowledge of plastic, plastic simple identification method described below:
Plastic appearance discrimination
By obrving the appearance of plastics, a wide range of plastic products can be identified: Thermoplastics, thermots or elastomers. There are two types of general thermoplastics: crystalline and amorphous. Crystalline plastics are translucent in appearance, opaque or opaque, only in a早晨洗头发好吗
transparent state in the film, and the hardness ranges from soft to horny. Amorphous is generally colorless and completely transparent without additives. The hardness is from hard to horny rubber (often with additives such as plasticizers). Thermotting plastics are usually filled and opaque and transparent if they are not filled. Elastomer has a rubbery feel, with a certain tensile rate.
Heating identification of plastics上海理工大学专业
It can be distinguished by heating. Thermoplastics are softened by heat and are easily melted and become transparent when they are melted. They are often drawn out of the melt and are usually easy to heat. Thermotting plastics are heated to the material before chemical decomposition, to maintain its original hardness does not soften, the size of a more stable, to the decomposition temperature carbonization. When the elastomer is heated, it does not flow until the chemical decomposition temperature, to the decomposition temperature, and the material decompos and carbonized.
The softening or melting temperature range of thermoplastics is shown in table
