1. PE yog dab tsi
PE, tseem hu ua polyethylene, feem ntau yog ua los ntawm cov dej zoo thiab cov dej noo, tab sis kev ua haujlwm tsis zoo ntawm cov pa roj thiab cov organic vapor tsis kam, tshuaj lom neeg ruaj khov, thiab cov suab nrov nrov tsis ua haujlwm ntawm chav tsev kub. Txawm li cas los xij, cov roj kuj tsis zoo me ntsis, muaj qee yam kev sib zog tensile thiab lub zog tsim kua muag, zoo yoog raws, tsis tshua muaj kev tiv thaiv siab heev, tuaj yeem hloov mus rau khov ntawm cov zaub mov, tab sis kev ua haujlwm siab tsis zoo. Feem ntau tsis tuaj yeem siv rau cov khoom noj khoom haus kub kom tsis muaj menyuam, gloss, transparency tsis siab. Kev luam ntawv ua haujlwm tsis zoo, thiab cov ntim txheej sab nrauv yuav tsum tau kho los ntawm corona thiab kev kho tshuaj deg los txhim kho kev luam ntawv. Nws yog ib qho yooj yim rau txheej txheem thiab daim ntawv, cov khoom yog hloov tau thiab muaj ntau haiv neeg, thiab lub tshav kub sealing kev ua tau zoo heev. PE resin nws tus kheej yog tsis muaj tshuaj lom, additive phiab yog tsawg heev, yog li nws raug suav hais tias yog cov khoom ntim zoo.
Thib ob, PE khau npog cov yam ntxwv
1, PE yog ib hom roj hmab saturated, uas muaj cov yam ntxwv zoo toughness, hnav tsis kam, softness thiab lwm yam.
2, PE yog non-toxic, tsis muaj cov hlau hnyav thiab PAHS, thiab nws cov khoom ua tau raws li qhov xav tau ntawm ib puag ncig.
3, PE muaj kev ua haujlwm siab, tuaj yeem npaj kom tau raws li ntau yam kev ua haujlwm sib txawv ntawm cov khoom.
4, PE ua haujlwm tau zoo, Mooney viscosity (ML121 1+4) hauv 50-100 muaj ntau qib xaiv los ntawm.
CPE yog dab tsi
CPE, tseem hu ua chlorinated polyether, kuj tuaj yeem hloov kho (cov ntsiab lus kev faib tawm yog 25% txog 42%, feem ntau yog li 36%). CPEs yog pheej yig dua li CSMs, thiab nws cov vulcanizates muaj tsawg compression mus tas li deformation, thiab nrog rau qhov nce ntawm cov ntsiab lus, cov roj kuj thiab nplaim taws retardant zog, tab sis cov cua kub kuj txo. CPE muaj huab cua tsis zoo thiab kub tsis kam, qhov kub tsis kam tiv thaiv tuaj yeem yog 150 txog 175 ° C, thiab nws cov roj zoo heev tuaj yeem ua rau nws nkag mus rau ntau hom roj, feem ntau yog siv hauv hose, hlau thiab cable sheathing.
Plaub, CPE khau npog nta
1, CPE yog ib hom roj hmab saturated, uas muaj tshav kub tsis kam mus rau oxygen aging, ozone aging, acid thiab alkali tsis kam, tshuaj muaj zog.
2. CPE muaj cov roj zoo heev, nrog rau kev ua haujlwm zoo rau ASTM 1 roj thiab ASTM 2 roj, uas yog piv rau NBR; Kev tiv thaiv zoo rau ASTM 3 roj, zoo dua CR, thiab piv rau CSM.
3, CPE muaj cov tshuaj chlorine, muaj cov nplaim hluav taws zoo heev, thiab muaj cov yam ntxwv tiv thaiv drip. Cov khoom siv hluav taws xob hluav taws xob nrog cov nplaim hluav taws zoo ua haujlwm thiab tus nqi qis tuaj yeem tau txais los ntawm qhov tsim nyog feem ntawm antimony nplaim taws retardant, chlorinated paraffin thiab Al (OH) 3.
4. CPE tsis muaj tshuaj lom, tsis muaj cov hlau hnyav thiab PAHS, thiab ua tau raws li qhov xav tau ntawm ib puag ncig.
5, CPE muaj kev ua haujlwm siab, tuaj yeem npaj kom tau raws li ntau yam kev ua haujlwm sib txawv ntawm cov khoom. CPE muaj cov khoom ua haujlwm zoo thiab Mooney viscosity (ML121 1+4) muaj nyob hauv ntau qib ntawm 50-100.
Tsib, pe khau npog thiab cpe khau npog uas yog qhov zoo
CEP thiab PE yog cov khoom siv yas, CPE khau npog yog cov khoom ntawm PE cov khoom tom qab chlorination, CPE khau npog nto muaj cov khoom tsis zoo, zoo dua li PE khau npog, tab sis ob lub khau npog tseem nyias, yooj yim hnav tsis zoo, yog koj xav siv cov khoom zoo dua, rov siv dua, xaiv cov khoom siv tsis-woven khau npog.
