Okwu Mmalite nke Plasticin Injin na mpaghara ngwa

1. Gịnị bụ plastik arụmọrụ dị elu ?

Odidi arụmọrụ dị elu bụ ụdị nke polymer ọhụrụ dị elu nke nwere arụmọrụ dị elu ma enwere ike iji ya ogologo oge na ọnọdụ okpomọkụ dị elu karịa 150 Celsius C. Plastik pụrụ iche nwere ọtụtụ njiri mara ndị ọzọ.

Enweghi ike ijikọ plastik arụ ọrụ ndị dị elu nwere ọtụtụ njiri mara na ihe ndị ọzọ, na-eguzogide nguzogide, ike ọgwụgwụ na-eguzogide, ihe dị mma na-eguzogide ike, ike dị mma, wdg. Ma maka ụlọ ọrụ nchekwa mba, ụgbọ elu, ariation, ụgbọ elu, ụgbọ mmiri na mpaghara ndị ọzọ, akụrụngwa ọgwụ, akụ na ụba na mmepe ndị agha na-enweghị atụ.

2. Kedu ihe ndị a gụnyere na plastik arụmọrụ dị elu ?

Ugbu a isi ihe dị iche iche arụmọrụ nke Plastics dị elu : polimide (pi), polyamine sulfide (PPS), polyhetherenenetone (PEK), wdg.

(1) Polyyathatetone Peek

Polyletattetone, a likear na-egbuke egbukepụ plastik, bụ akụkọ ọdịnala pụrụ iche na-enweghị atụ, ejirila ihe dị oke mkpa gbachitere ihe ndị agha gbara agba agbachitere kemgbe.

Enwere ike iji iko ya ma ọ bụ nwee ike iji eriri nwere ike iji ya na 250 Celsius C ruo ogologo oge. Uru dị ala, oke modulus dị egwu, akụrụngwa dị mma dị mma, nguzogide na mgbasa ozi dị iche iche na kemịkalụ kemịkalụ. Ngwa ngwa: Eletriki na elektrọnik, igwe, ụlọ ọrụ na-eme ihe, nyocha mmanụ, na-echebe, na-echebe mkpuchi, wdg.

(2) polyphenlene sulfide pps

A maara PPS dị ka plastik nke Injinịa nke isii, bụ ọrụ nnwere onwe China nke plastik injinịa pụrụ iche. Nwere ike nkwụsi ike dị mma, iji ogologo oge nke okpomọkụ kachasị elu na ihe ọkụkụ, ihe ruru mmadụ 220 ~ 240, igwe eletriki, ngwa ngwa ngwa ngwa, wdg.

(3) polyetamidide pei

Enwere ike iji polyetamidide n'okpuru okpomọkụ nke -160 Celsius C ~ 180 Celsius C ruo ogologo oge. Ọ nwere oke okpomọkụ na-eguzogide, dị elu, dị elu, dị elu modulus na nnukwu anwụrụ ọkụ, na elu dielectric mgbe niile na ọnwụ.
