Chlorinated polyethylene (CPE) yog cov khoom hloov kho chlorinated ntawm high-density polyethylene (HDPE), siv ua cov khoom hloov kho rau PVC. Cov ntsiab lus chlorine ntawm CPE yuav tsum nyob nruab nrab ntawm 35-38%. Vim nws tiv taus huab cua zoo heev, tiv taus txias, tiv taus hluav taws, tiv taus roj, tiv taus kev cuam tshuam (CPE yog elastomer), thiab kev ruaj khov tshuaj lom neeg.
Chlorinated polyethylene (CPE) yog cov khoom hloov kho chlorinated ntawm cov polyethylene siab (HDPE), siv ua cov khoom hloov kho rau PVC, Cov ntsiab lus chlorine ntawm CPE yuav tsum nyob nruab nrab ntawm 35-38%. Vim nws tiv taus huab cua zoo heev, tiv taus txias, tiv taus hluav taws, tiv taus roj, tiv taus kev cuam tshuam (CPE yog elastomer), thiab kev ruaj khov tshuaj lom neeg, nrog rau nws qhov sib xws zoo nrog PVC, CPE tau dhau los ua cov khoom siv hloov kho toughening feem ntau hauv PVC ua.
1 Kev Teeb tsa Molecular ntawm HDPE
Vim yog cov txheej txheem sib txawv thaum lub sijhawm polymerization ntawm PE, muaj qee qhov sib txawv hauv cov qauv molecular thiab cov khoom ntawm nws cov polymer HDPE. Cov khoom ntawm CPE tom qab chlorination ntawm HDPE nrog cov khoom sib txawv kuj sib txawv. CPE cov chaw tsim khoom yuav tsum xaiv cov hmoov tshwj xeeb HDPE kom tsim tau cov tshuaj CPE tsim nyog.
2. Cov xwm txheej chlorination, piv txwv li cov txheej txheem chlorination
CPE, ua ib qho kev hloov kho PVC, feem ntau yog tsim los ntawm kev siv tshuaj chlorination los ntawm kev siv cov txheej txheem aqueous suspension chlorination. Cov xwm txheej tseem ceeb ntawm cov txheej txheem chlorination no yog lub zog lub teeb, cov tshuaj pib, lub zog ntawm cov tshuaj tiv thaiv, qhov kub ntawm cov tshuaj tiv thaiv, lub sijhawm tiv thaiv, thiab cov xwm txheej ntawm kev ua kom tsis muaj zog. Lub hauv paus ntsiab lus ntawm PE chlorination yog qhov yooj yim, tab sis cov txheej txheem chlorination nyuaj dua.
Vim tias kev nqis peev me me rau cov khoom siv los tsim CPE, ntau lub Hoobkas tsim CPE me me twb tau tawg thoob plaws Suav teb. Qhov no tsis yog tsuas yog ua rau muaj kuab paug rau ib puag ncig xwb, tab sis kuj yog ib qho tseem ceeb rau qhov tsis ruaj khov ntawm CPE zoo.
Tam sim no, muaj ntau hom CPE tsis zoo hauv khw. Feem ntau, muaj ob hom CPE tsis zoo. Ib qho yog vim qee lub Hoobkas tsim khoom tsis muaj cov txheej txheem kev siv tshuab thiab cov txheej txheem chlorination qub dhau lawm. Lwm txoj hauv kev yog sib tov qee qhov calcium carbonate lossis talc hmoov hauv CPE kom koom nrog kev sib tw tsis ncaj ncees.
