Qhov txawv ntawm cov polyethylene uas muaj chlorinated ntau thiab cov roj hmab uas muaj chlorinated ntau yog dab tsi?

Cov polyethylene uas muaj chlorinated ntau (HCPE) thiab cov roj hmab uas muaj chlorinated (CR) uas tsim los ntawm Bontecn Group Tuam Tshoj yog ob hom polymers uas siv dav hauv cov teb ntawm cov tshuaj tiv thaiv xeb thiab cov nplaum, tab sis lawv muaj qhov sib txawv tseem ceeb hauv cov qauv tshuaj, cov yam ntxwv kev ua tau zoo, thiab cov xwm txheej siv tau.
1. Cov qauv tshuaj lom neeg thiab kev phooj ywg ib puag ncig
HCPE: Npaj los ntawm kev hloov kho chlorine ntawm polyethylene, nrog rau kev faib tawm ntawm cov chlorine atoms thiab cov ntsiab lus chlorine feem ntau ≥ 65%. Tsim los ntawm txoj kev ncua dej, nws tsis muaj kuab paug rau cov kuab tshuaj thiab ua tau raws li cov kev cai tiv thaiv ib puag ncig.
CR: Nws yog ua los ntawm chlorination ntawm cov roj hmab ntuj lossis cov roj hmab hluavtaws, nrog cov ntsiab lus chlorine ntawm kwv yees li 60-65%. Kev tsim cov kuab tshuaj ib txwm muaj yuav ua rau muaj cov tshuaj lom neeg thiab kev tiv thaiv ib puag ncig tsis zoo.
2. Kev sib piv kev ua tau zoo
Kev tiv thaiv huab cua: HCPE muaj kev tiv thaiv ozone thiab ultraviolet zoo dua, ua rau nws tsim nyog rau cov chaw nyob sab nraum zoov ntev xws li choj thiab nkoj; CR yooj yim puas tsuaj ntawm qhov kub siab thiab tsis muaj zog tiv thaiv huab cua.
Kev tiv thaiv tshuaj lom neeg: Ob qho tib si yog cov kua qaub thiab alkali tiv taus, tab sis HCPE muaj kev kam rau cov tshuaj oxidants muaj zog (xws li cov kua qaub sulfuric uas muaj concentrated), tsis muaj blistering lossis shedding tom qab 30 hnub ntawm kev sim.
3. Qhov sib txawv ntawm cov teb thov
HCPE:
Cov txheej txheem tiv thaiv xeb hnyav (cov khoom siv tshuaj lom neeg, cov kav dej roj av)
Cov ntaub ntawv tiv taus hluav taws (cov txheej tiv taus hluav taws, cov ntaub thaiv cable)
Cov nplaum zoo kawg (rau kev sib txuas nrog PVC thiab hlau)
CR‌:
Cov txheej txheem tiv thaiv xeb ib txwm muaj (rau cov nkoj thiab cov thawv)
Ink thiab printing teb
4. Kev Lag Luam thiab Tus Nqi
HCPE: Vim yog tus nqi siab dua ntawm cov txheej txheem uas tsis ua rau ib puag ncig puas tsuaj tab sis kev ua tau zoo dua, nws maj mam hloov CR.
CR: Tus nqi qis dua, tab sis vim yog cov cai ib puag ncig, qhov kev siv tau txwv.
5. Kev txhawb nqa kev siv
Ob qho tib si sib xws nrog lwm cov resins xws li epoxy resin thiab acrylic acid, tab sis HCPE zoo dua rau cov txheej txheem sib xyaw ua ke uas xav tau kev nplaum siab lossis tiv taus huab cua.
