PE-X: Hla-txuas polyethylene 1
PAP: Aluminium-yas yeeb nkab 2
PP-B: Impact-resistant copolymer polypropylene (Korea siv los hu nws PP-C)
PP-R: random copolymer polypropylene
PB: Polybutene yog kub resistant
PE-RT: Polyethylene
Lus Cim 1: Hla-txuas polyethylene muab faib ua peroxide cross-linking (PE-Xa), silane cross-linking (PE-Xb), electron beam cross-linking (PE-XC) thiab azo cross-linking (PE-Xd) raws li txoj kev tsim khoom. ) plaub. Ntawm lawv, peroxide cross-linking thiab silane cross-linking yog ob hom cross-linked polyethylene yeeb nkab khoom uas nquag siv hauv Suav teb.
Txawm li cas los xij, peroxide cross-linking tsis tau siv dav vim yog kev nkag mus rau oxygen ntau dhau. Silane cross-linking raug txwv hauv Tebchaws Europe hauv xyoo 2004 vim tias tus neeg sawv cev sib txuas silane yog tshuaj lom. Electron beam cross-linking (PE-XC) yog ib qho kev noj qab haus huv thiab ib puag ncig tus phooj ywg yeeb nkab uas siv lub cev los hloov cov qauv molecular. , azo-crosslinking (PE-Xd) yog nyob rau hauv qhov kev sim.
Faj seeb 2: Muaj peb hom aluminium-yas composite kav hauv khw, PE / AL / PE; PE / AL / XPE; XPE/AL/XPE. Qhov thib ib yog cov txheej sab hauv thiab sab nrauv yog polyethylene, qhov thib ob yog cov txheej sab hauv yog cross-linked polyethylene, txheej txheej yog polyethylene, qhov thib peb yog cov txheej sab hauv thiab sab nrauv yog ob qho tib si cross-linked polyethylene, thiab nruab nrab. txheej yog aluminium. Thawj hom feem ntau yog siv rau cov kav dej txias, thiab ob lub tom kawg yog feem ntau siv rau cov kav dej kub, uas tuaj yeem siv los ua cov kav dej hauv pem teb.
