Dab tsi poob yuav tshwm sim los ntawm qhov tsis zoo chlorinated polyethylene CPE hauv PVC ua?

Chlorinated polyethylene (CPE) yog chlorinated hloov khoom ntawm high-density polyethylene (HDPE), siv los ua kev hloov kho rau PVC, Cov ntsiab lus chlorine ntawm CPE yuav tsum nyob nruab nrab ntawm 35-38%. Vim nws cov huab cua zoo heev, tiv taus txias, nplaim taws, roj tsis kam, cuam tshuam tsis kam (CPE yog elastomer), thiab tshuaj lom neeg ruaj khov.

Vim nws cov huab cua zoo heev, tiv taus txias, nplaim taws, tiv thaiv roj, cuam tshuam tsis kam (CPE yog ib qho elastomer), thiab tshuaj lom neeg ruaj khov, nrog rau nws qhov zoo sib xws nrog PVC, CPE tau dhau los ua qhov feem ntau siv cov kev hloov kho toughening hauv PVC. ua.
1 Molecular Configuration ntawm HDPE
Vim muaj cov txheej txheem sib txawv thaum lub sij hawm cov tshuaj tiv thaiv polymerization ntawm PE, muaj qee qhov sib txawv ntawm cov molecular configuration thiab cov khoom ntawm nws cov polymer HDPE. Cov khoom ntawm CPE tom qab chlorination ntawm HDPE nrog cov khoom sib txawv kuj txawv. CPE manufacturers yuav tsum xaiv cov HDPE tshwj xeeb hmoov resins thiaj li tsim tau CPE resins.
2. Chlorination tej yam kev mob, piv txwv li cov txheej txheem chlorination
CPE, raws li kev hloov pauv ntawm PVC, feem ntau yog tsim los ntawm cov tshuaj tiv thaiv chlorination siv aqueous suspension chlorination method. Cov xwm txheej tseem ceeb ntawm cov txheej txheem chlorination no yog lub teeb lub zog, qhov pib siv tshuaj, tshuaj tiv thaiv siab, qhov kub thiab txias, lub sijhawm tshuaj tiv thaiv, thiab cov tshuaj tiv thaiv tsis zoo. Lub hauv paus ntsiab lus ntawm PE chlorination yog qhov yooj yim, tab sis cov txheej txheem chlorination yog qhov nyuaj dua.
Vim muaj kev nqis peev me me hauv cov cuab yeej siv los tsim CPE, ntau lub tsev tsim khoom me me CPE twb tau tawg thoob plaws hauv Suav teb. Qhov no tsis yog tsuas yog ua rau muaj kuab paug rau ib puag ncig ecological, tab sis kuj yog ib qho ntawm cov laj thawj tseem ceeb rau kev tsis ruaj khov ntawm CPE zoo.
Tam sim no, muaj ntau tus CPE tsis zoo ntawm lub khw. Feem ntau, muaj ob hom CPE tsis zoo. Ib qho yog vim qee qhov chaw tsim khoom tsis muaj cov txheej txheem kev ua haujlwm thiab cov txheej txheem chlorination dhau los. Lwm txoj kev yog sib tov ib qho nyiaj ntawm calcium carbonate lossis talc hmoov hauv CPE los koom nrog kev sib tw tsis ncaj ncees.
