Plastic characteristic advantage: the proportion of light, good insulation, easy processing, color more, does not rust.
Disadvantages: low intensity, easy ageing, with static electricity.
2, 1, what is plastic, plastic basic plasticizing processing, under the condition of heat compression can be cooled to form a fixed shape of polymer.
2, the classification of the plastic (
Thermoplastics, plasticizing melt when heated, cooled the process of solidification, the category of plastics can be repeatedly.
Thermosetting plastics plasticized melt when heated, cooled solidified into molten melt material, this process can not be repeated a kind of plastic.
Three, the classification of the varieties of plastic manufacturing process.
