PE Polyethylene

Polyethylene feem ntau muab faib ua low density polyethylene (LDPE), medium ntom polyethylene (MDPE) thiab high density polyethylene (HDPE), thiab lawv daim ntawv thov txawv. LDPE feem ntau yog siv los tsim cov khoom hnyav xws li cov yeeb yaj kiab thiab cov fibers, thiab thaum nws los txog rau kev tsim cov kav dej txhaj tshuaj, HDPE lossis MDPE feem ntau yog siv.

PE kav dej feem ntau yog dub thiab feem ntau yog siv los thauj cov dej txias.

Hauv kev tsim cov kav dej, vim tias cov khoom siv hluav taws xob tsis zoo ntawm polyethylene, nws yuav tsum tau hloov kho nyob rau qee lub sijhawm xav tau siab (xws li cov tshuab cua sov), yog li muaj PE-RT thiab PE-X.

PE-RT yog hais txog thaum tshav kub kub-resistant polyethylene. Nws siv cov txheej txheem ntawm copolymerization ntawm ethylene thiab octene los txhim kho cov cua sov ntawm PE los ntawm kev tswj tus naj npawb thiab kev faib tawm ntawm cov saw hlau sab kom tau txais cov qauv molecular tshwj xeeb.

PE-X yog hais txog kev sib txuas ntawm polyethylene. Kev sib txuas sib txuas ua rau cov kab hluav taws xob macromolecular qauv ntawm polyethylene rau hauv cov qauv peb-dimensional network, yog li txhim kho nws qhov kub thiab txias tsis kam. Hla-txuas polyethylene tsis yog thermoplastic thiab tsis tuaj yeem kub-kua sib raug zoo. Tam sim no kev lag luam PE-X suav nrog PE-Xa, PE-Xb, PE-Xc. Nws yog ib qho tsim nyog sau cia tias a thiab b ntawm no tsis yog hais txog cov khoom qib A lossis B, tab sis lawv nyob hauv qhov sib txuas sib txuas. Cov kev siv yog txawv.

PE-RT thiab PE-X feem ntau yog siv los ua cov kav dej hauv pem teb.
