Rau cov tawv PVC shrinkable zaj duab xis, nws yog qhov zoo tshaj plaws los siv ncua kev kawm hom 6 lossis 7 resin, txawm hais tias nyob rau hauv cov hlau thiab cable txuas nrog cov yeeb yaj kiab shrinkable, lub cev tiv thaiv tsis siab li 2 lossis 3 resin, tab sis 7 resin molding, ntau lawm. kev xyaum tau ua pov thawj tias kev siv 2 lossis 3 resin, nws yog ib qho nyuaj rau kev tsim, tawv PVC shrinkable zaj duab xis ntau lawm nyuaj thiab nkig, tsis tuaj yeem folded thiab dov.
Thaum siv plasticizer, lub thermal shrinkage kub txo nrog qhov nce ntawm plasticizer cov ntsiab lus.Piv txwv li, kev siv tshem tawm hom 3 PVC tsob ntoo roj hmoov, ntxiv DOP plasticizer ntawm 30-50 PHR, tuaj yeem ua rau biaxial tensile ntawm li 70 ℃, thiab nws cov khoom tuaj yeem ntsws ntawm li 40 ℃, tsis tuaj yeem khaws cia rau hnub kub.Ntxiv mus, nrog kev nce ntawm cov ntsiab lus plasticizer, lub cev tiv thaiv ntawm lub tes tsho kub-shrinkable rau hlau thiab cable txo.Yog li ntawd, thaum peb siv PVC tshav kub-shrinkable tes tsho rau hlau thiab cable sib txuas, peb tseem siv hom 6 los yog 7 resins uas yooj yim rau txheej txheem.Txhawm rau txhim kho cov rwb thaiv tsev, peb siv cov cua sov stabilizer ua ke nrog peb cov ntsev thiab ob lub ntsev thiab tsim nyog txhim kho cov yeeb yaj kiab tuab kom ntseeg tau tias cov rwb thaiv tsev.P83 nitrile roj hmab muaj zoo machinability, elasticity, txias tsis kam, thiab tuaj yeem txhim kho lub zog, txhim kho kev ntxhov siab tawg tsis kam ntawm PVC khoom.Active CaCO3 feem ntau txhim kho cov rwb thaiv tsev thiab nplaim taws retardancy ntawm cov khoom thiab txo tus nqi.
