Kev faib tawm ntawm cov khoom yas

Raws li lawv cov khoom tom qab cua sov

Thermosetting Plastics: Cov yas no yog tus cwj pwm los ntawm kev ua kom zoo rau hauv lawv daim ntawv kawg ntawm qhov kub thiab txias, lossis tom qab sib ntxiv ntawm tus neeg sawv cev kho.

Plastics kho tau yog tawv, insoluble nyob rau hauv tej yam hnyav, thiab tsis tuaj yeem softened dua los ntawm cua sov. Cov cua kub ntau dhau yuav ua rau lawv decompose.

Thermoplastic Plastics: Cov yas no soften thaum rhuab thiab tawv thaum txias. Thaum ua tiav, lawv feem ntau tsuas yog hloov lub cev thaum khaws lawv cov khoom siv tshuaj.

Los ntawm Daim Ntawv Thov

General-Plastics Lub Hom Phiaj: Cov yas no yog cov yam ntxwv ntawm cov ntim ntau lawm, siv dav, thiab tus nqi qis. Lawv suav txog kwv yees li 80% ntawm tag nrho cov khoom yas. Cov ntau yam muaj xws li: polyethylene, polyvinyl chloride, polypropylene, polystyrene, phenolic thiab amino plastics, thiab lwm yam.

Engineering Plastics: Cov no feem ntau xa mus rau cov yas uas tuaj yeem siv los ua cov khoom siv hauv engineering technology. Cov yam ntxwv tseem ceeb ntawm cov yas no yog cov neeg kho tshuab siab, muaj zog tiv thaiv cov tshuaj corrosion thiab kub tsis kam, tso cai rau lawv hloov cov hlau los yog siv rau lwm yam tshwj xeeb. Ntau yam muaj xws li: polyamide, polycarbonate, polyoxymethylene, polysulfone, ABS, polyphenylene ether, fluoroplastics, thiab lwm yam.

Classification los ntawm Flammability

Flammable Plastics: Cov yas no kub hnyiab tau thaum raug nplaim taws thiab nyuaj rau tua. Piv txwv muaj xws li nitrocellulose plastics. Cov yas no tau muab cais ua cov khoom siv phom sij.

Plastics Combustible Plastics: Cov yas no tsis ua rau tus kheej - tua thaum raug nplaim taws, tab sis hlawv kuj sai heev. Piv txwv li polyethylene thiab polypropylene.

Nplaim taws- Cov Plastics Retardant: Cov yas no tuaj yeem kub hnyiab tau hauv qhov qhib nplaim taws tab sis tua sai sai tom qab cov nplaim hluav taws raug tshem tawm. Piv txwv xws li phenolic plastics, cellulose acetate plastics, thiab polyvinyl chloride plastics.
