plastics main characteristic

The plastics main characteristic
① Majority of plastics qualities are light, the chemistry is stable, can't rust eclipse;②Bear impact like;③Have better transparent and bear to wear sex;④Insulate sex well, transmit heat sex low;⑤Generally model sex and apply color sex well, process cost low;⑥Great parts of plasticses heat-proof differ, the hot rate of expansion is big, easily burnable;⑦The size stability is bad and easily transform;⑧Majority of plasticsesplastic bag manufacturer bear low temperature to differ, the low temperature bottom changes frailty;⑨Easily aging;⑩Some plasticses are easily dissolved to melting agent.

The plastics can classified into hot solid and hot plasticity two types of, the former can not re- mold an usage, the latter can repeat production again.

The structure of plastics Gao member
Basic have 2:The first is line type structure, have the high mark son compound of this kind of structure to be called a line type high mark son compound;The second is body figure structure, have the high mark son of this kind of structure to combine to be called the body figure high mark son compound.Some high mark sons take to pay a chain and is called to pay chain high mark son and belong to a line type toilet facial paper maunfacturerstructure.Some high mark sons although the member has been already handed over to unite,hand over allied less, be called net structure, belong to body figure structure.

Two kinds of different structure, express two kinds of contrary functions.Line type structure(include to pay chain structure) Gao Ju Wu because of existing independent member, so have flexibility, plasticity, can fuse in the melting agent, heat ability meltdown, degree of hardness and brittleness smaller characteristics.Body figure structure Gao Ju Wu has no the big member of independence existence, so there are no flexibility and plasticity, indissoluble with meltdown, can dissolve bulge, degree of hardness and brittleness bigger.Plastics two kinds of high mark sons of structure then all have, from line type what high mark son make into is a hot Su plastics,hong kong attractions is been a hot solid sex plastics by body figure high mark what son make into.
