Dab tsi yog sib txawv ntawm pe khau npog thiab cpe khau npog
Chlorinated polyethylene (PE) (CPE) yog cov khoom siv hauv cov ntsiab lus xim siab (fèn), qhov zoo li yog hmoov dawb, tsis muaj tshuaj lom thiab tsis muaj ntxhiab, nrog huab cua zoo ua hauj, ozone tsis kam, tshuaj lom neeg kuj tiv thaiv kev laus thiab cov laus, thiab cov roj zoo heev kev ua hauj Kuj, nplaim retardancy thiab xim muaj nuj nqi. Yog li koj puas paub qhov txawv ntawm pe khau npog thiab cpe khau npog? Cov khau dab tsi haum rau cov khau khau khiab tsis npog npog? Cia' s ua tibzoo saib ntawm Baibai Kev Nyab Xeeb Net.
1) CPE yog roj hmab uas muaj roj nplua nyeem nrog kub zoo tshaj tawm oxygen oxygen, kev laus ozone, acid thiab alkali tsis kam, thiab tshuaj lom neeg kuj.
2) CPE muaj cov roj ua tau zoo. Ntawm lawv, nws muaj qhov ua tau zoo rau ASTM No. 1 roj thiab roj ASTM No. 2, uas yog sib npaug rau NBR; thiab nws muaj cov tshuaj tiv thaiv zoo rau ASTM No. 3 roj, uas yog zoo dua li CR thiab yog sib npaug rau CSM.
3) CPE muaj cov tshuaj chlorine, muaj cov nplaim zoo ua kom zoo, thiab muaj cov yam ntxwv ntawm kev hlawv thiab xeb kev tiv thaiv. Ua ke nrog antimony nplaim taws retardant, chlorinated dawb siv quav ciab, thiab Al (OH) 3, qhov sib piv tsim nyog tuaj yeem tau txais cov nplaim hluav taws kub cov ntaub ntawv nrog cov nplaim taws retardant kev ua tau zoo thiab tus nqi qis.
4) CPE yog non-toxic, tsis muaj hnyav hlau thiab PAHS, thiab nws yog qhov tsim nyog rau kev tiv thaiv ib puag ncig cov cai.
5) CPE muaj qhov ua haujlwm siab thiab tuaj yeem tsim cov khoom tsim nyog rau ntau yam kev ua haujlwm. CPE muaj cov txheej txheem ua tiav zoo, Mooney viscosity (ML121 1+4) muaj ntau yam khoom lag luam kom xaiv ntawm 50-100.
CPE khau npog yog ua los ntawm cov khoom siv chlorinated PE. CPE khau npog muaj cov xaim hluav taws xob tsis zoo rau saum npoo, uas zoo dua li PE khau npog. Txawm li cas los xij, ob txoj hlua khau ob zaug tseem yuag me me thiab yuav tawg yog tias lawv yooj yim hnav. Yog tias koj xav siv qhov zoo dua qub, yog tias koj rov siv nws, xaiv cov khau tsis-ntaub npog.
Lus Askiv lub npe ntawm polyethylene: polyethylene, hu ua PE, yog cov thermoplastic cob ua los ntawm polymerization ntawm ethylene. Kev lag luam, nws tseem suav nrog cov tshuab copolymer ntawm ethylene thiab ib qho me me ntawm α-olefin. Polyethylene muaj ntxhiab tsw, tsis muaj kuab lom, hnov zoo li siv quav ciab, muaj qhov kub tsis zoo tiv thaiv qis (qhov kub daim ntawv thov qis kawg yuav ncav cuag -70 ~ -100 ℃), muaj cov tshuaj lom neeg zoo, thiab tuaj yeem tiv taus cov kua qaub thiab alkali tsis zoo (tsis tiv taus oxidation Acid), insoluble nyob rau hauv cov kev daws dav dav ntawm chav sov, nqus dej tsis tshua muaj dej, thiab kuj yog khau tsis npog.
