Cov txiaj ntsig thiab kev ua haujlwm ntawm cov polyethylene HCPE uas muaj chlorinated ntau

1. Cov txiaj ntsig tseem ceeb
Kev tiv thaiv huab cua thiab kev tiv thaiv xeb: HCPE muaj cov qauv molecular ruaj khov, kev faib tawm ntawm cov chlorine atoms, thiab tuaj yeem tiv taus kev xeb los ntawm UV, ozone, acid, alkali, ntsev thiab lwm yam tshuaj lom neeg, ua rau nws haum rau cov chaw ib puag ncig hnyav.
Kev tiv thaiv hluav taws: Nws tuaj yeem tua nws tus kheej tom qab 15 vib nas this ntawm kev sib xyaw, ua tau raws li qhov yuav tsum tau ua ntawm kev nyab xeeb hluav taws.
Kev tawv tawv kub tsawg: tswj tau qhov yooj ywm txawm tias ntawm qhov kub qis dua 30 ℃, tsim nyog rau kev siv hauv thaj chaw txias.
Kev phooj ywg ib puag ncig: tsis muaj tshuaj lom thiab tsis muaj ntxhiab, nrog rau kev ua qias tuaj tsawg thaum lub sijhawm tsim khoom, ua raws li cov qauv khoom siv ntsuab.
2. Cov haujlwm tseem ceeb
(1) Kev tiv thaiv xeb txheej teb
Ua ib yam khoom siv hauv paus, nws yog siv ua ib qho tshuaj tiv thaiv xeb rau cov nkoj, choj, cov khoom siv tshuaj lom neeg, thiab lwm yam. Nws tiv taus dej, roj, kua qaub, alkali, ntsev, thiab xeb hauv huab cua, muaj kev nplaum zoo, thiab yooj yim rau kev saib xyuas (cov txheej tshiab thiab qub tuaj yeem sib xyaw ua ke).
(2) Kev Hloov Kho Cov Nplaum thiab Cov Kua Xim
Cov nplaum: HCPE-H uas muaj viscosity siab tuaj yeem hloov cov nplaum vinyl chloride thiab siv rau kev sib txuas cov kav dej PVC thiab cov khoom siv hlau. Tom qab yaj hauv cov kuab tshuaj xws li toluene, nws tsim cov kua nplaum muaj zog heev.
Kua mem: ua kom muaj kev tiv thaiv kev hnav, kev tiv thaiv corrosion, thiab kev tiv thaiv hluav taws, tsim nyog rau kev luam ntawv siab.
(3) Lwm yam kev siv hauv kev lag luam
Ua ib qho kev hloov pauv rau PVC, nws ua rau cov khoom yas muaj zog dua.
Siv rau cov ntaub thaiv cable, cov khoom siv roj hmab (xws li cov hoses, daim kab xev), thiab kev hloov kho cov khoom siv sib nqus.
3. Kev faib tawm khoom thiab ntim khoom
HCPE-H: Cov viscosity siab, 25kg/hnab, tsim tshwj xeeb rau PVC nplaum.
HCPE-M: Qhov nruab nrab viscosity, siv rau cov txheej tiv thaiv xeb/tiv taus hluav taws.
HCPE-L: Tsis tshua muaj viscosity, sib xws nrog acrylic resin, tsim nyog rau kev tiv thaiv cov kav dej hauv av.
