Chlorinated polyethylene (CPE) ke sehlahisoa se fetotsoeng sa chlorinated polyethylene e phahameng haholo (HDPE). E le sesebelisoa sa ho lokisa bakeng sa PVC, litaba tsa chlorine tsa CPE li lokela ho ba pakeng tsa 35-38%. Ka lebaka la ho hanyetsa boemo ba leholimo bo botle, ho hanyetsa serame, ho hanyetsa lelakabe, ho hanyetsa oli, ho hanyetsa tšusumetso (CPE ke elastomer), le botsitso ba lik'hemik'hale.
Chlorinated polyethylene (CPE) ke sehlahisoa se fetotsoeng sa chlorinated polyethylene e phahameng haholo (HDPE). E le sesebelisoa sa ho lokisa bakeng sa PVC, litaba tsa chlorine tsa CPE li lokela ho ba pakeng tsa 35-38%. Ka lebaka la ho hanyetsa boemo ba leholimo bo botle, ho hanyetsa serame, ho hanyetsa lelakabe, ho hanyetsa oli, ho hanyetsa phello (CPE ke elastomer), le botsitso ba lik'hemik'hale, hammoho le ho lumellana ha eona hantle le PVC, CPE e fetohile mokhoa o sebelisoang ka ho fetisisa o sebelisoang ka matla ho PVC. ho sebetsa.
1. Tlhophiso ea Molek'hule ea HDPE
Ka lebaka la maemo a fapaneng a ts'ebetso nakong ea karabelo ea polymerization ea PE, ho na le liphapang tse itseng mabapi le tlhophiso ea limolek'hule le thepa ea polymer HDPE ea eona. Thepa ea CPE ka mor'a chlorination ea HDPE e nang le thepa e fapaneng le eona e fapane. Baetsi ba CPE ba tlameha ho khetha li-resin tsa phofo tse khethehileng tsa HDPE e le hore ba hlahise li-resin tse tšoanelehang tsa CPE.
2. Maemo a chlorination, ke hore, ts'ebetso ea chlorination
CPE, joalo ka PVC processing modifier, hangata e thehoa ka chlorination reaction ho sebelisa aqueous suspension chlorination method. Maemo a bohlokoa a ts'ebetso ena ea chlorination ke matla a bobebe, tekanyo ea ho qala, khatello ea karabelo, mocheso oa karabelo, nako ea karabelo, le maemo a karabelo a ho se nke lehlakore. Molao-motheo oa PE chlorination o batla o le bonolo, empa mochine oa chlorination o rarahane haholoanyane.
Ka lebaka la matsete a manyane a lisebelisoa tsa tlhahiso ea CPE, limela tse ngata tse nyane tsa tlhahiso ea CPE li se li hasane hohle China. Sena ha se bake feela tšilafalo tikolohong ea tikoloho, empa hape ke le leng la mabaka a bohlokoa a ho se tsitse ha boleng ba CPE.
Hajoale, ho na le palo e kholo ea CPE ea boleng bo tlase 'marakeng. Ka kakaretso, ho na le mefuta e 'meli ea CPE ea boleng bo tlaase. E 'ngoe e bakoa ke limela tse ling tsa tlhahiso ha li na maemo a theknoloji le mekhoa ea khale ea chlorination. Mokhoa o mong ke ho kopanya palo e itseng ea calcium carbonate kapa talc powder ho CPE ho kenya letsoho tlhōlisanong e sa lokang.
