Njira yopangira chidebe cha polyethylene chophimbidwa ndi chlorine cha mawaya ndi zingwe:

1. Kusakaniza
Poyerekeza ndi mitundu yachikhalidwe ya rabara ya chloroprene. Polyethylene yokhala ndi chlorine siifuna pulasitiki ndipo siifuna kusungidwa pambuyo pa pulasitiki. Zowonjezera zamadzimadzi mu fomula ya polyethylene yokhala ndi chlorine zimatha kusunthidwa ndikuyamwa kudzera mu ufa wina panthawi yosakaniza, zomwe zingapewe kuyeretsa ndi kudontha panthawi yosakaniza yeniyeni. Kutentha kwa vulcanization kwa polyethylene yokhala ndi chlorine kumafunika kupitirira 160 ℃ Kupanga kosalekeza kumatha kuchitika ndi madzi ozizira, koma kutentha nthawi zambiri sikupitirira 160 ℃. Chifukwa chake chogwiritsira ntchito vulcanization chomwe chimagwiritsidwa ntchito mu polyethylene yokhala ndi chlorine sichiyenera kuwonjezeredwa padera ndi zowonjezera zina, ndipo chingasakanizidwe mwachindunji ndi ufa wina. Zofunikira kutentha kosakaniza kwa polyethylene yokhala ndi chlorine ndi zazikulu, kuyambira 40 ℃ mpaka 120 ℃, ndipo sipadzakhala kukanikiza kapena kutentha kwa ma rollers. Mukamagwiritsa ntchito chosakanizira chotseguka, ndikofunikira kuzimitsa madzi ozizira kapena kuyatsa nthunzi nthawi yake. Chifukwa polyethylene yokhala ndi chlorine imapanga mphamvu zambiri zotentha chifukwa cha kukangana panthawi yosakaniza, ndikofunikira kuwonjezera madzi ozizira okwanira mukasakaniza mu chosakanizira chamkati. Kutentha kwa kugawa nthawi zambiri kumakhala pakati pa 110 ℃ ndi 120 ℃ Izi zimathandiza kuti pakhale ntchito yambiri yosakaniza mosalekeza popanda kuwononga ubwino wa polyethylene wothira chlorine.
2. Malo oimika magalimoto ndi malo oyeretsera zinthu zotentha
Poyerekeza ndi rabala ya chloroprene, rabala yosakaniza ya polyethylene yokhala ndi chlorinated polyethylene imakhala ndi kukhazikika bwino kosungira ndipo sikufuna kusungidwa kutentha kochepa. Kutentha kwambiri m'chilimwe sikukhudza mwachindunji. Polyethylene yokhala ndi chlorinated sikufuna kuziziritsidwa panthawi yoyeretsedwa yotentha, ndipo kutentha koyeretsedwa nthawi zambiri kumakhala pamwamba pa 50 ℃.
3. Kupanga zipolopolo zoteteza mawaya ndi zingwe
Polyethylene yokhala ndi chlorine nthawi zambiri ingagwiritsidwe ntchito popanga ma waya ndi ma cable sheath pogwiritsa ntchito ma screw extruders aatali kapena ma short screw extruders. Kawirikawiri, ma waya ndi ma cable sheath opangidwa ndi ma screw extruders aatali adzakhala owala, ofewa, komanso okhala ndi magawo owonjezera. Mukatulutsa guluu wa polyethylene wokhala ndi chlorine, kutentha kwa mutu nthawi zambiri kumakhala pakati pa 6 ° C ndi 90 ° C. Chifukwa cha kutentha kwakukulu komwe kumachitika panthawi yoyenga polyethylene yokhala ndi chlorine, kutentha mkati mwa zinthu za rabara kudzakhala kwakukulu, nthawi zambiri pakati pa 90 ℃ ndi 120 ℃. Chifukwa chake, mukagwiritsa ntchito screw extruder yayitali, ndikofunikira kuyang'anira ndikuwongolera kutentha koyambira kuti mupewe kuyaka kwa zinthu za rabala.
4. Njira yopangira sulfur
Poyerekeza ndi mitundu ina ya zipangizo za rabara zomwe zimagwiritsidwa ntchito nthawi zambiri, kutentha komwe kumafunika pa njira yopangira vulcanization ya polyethylene yokhala ndi chlorine kumakhala kokwera, nthawi zambiri pakati pa 160 ℃ ndi 180 ℃. Zofunikira pa vulcanization ya waya wa polyethylene wokhala ndi chlorinated ndi rabara ya chingwe ndi izi:; Pamene kuthamanga kwa nthunzi yodzaza ndi 054 MPa, kutentha kwa vulcanization ndi 160 ℃ ndipo nthawi yopangira vulcanization nthawi zambiri imakhala pakati pa mphindi 25 ndi mphindi 30. Pamene kuthamanga kwa nthunzi yodzaza ndi 098MFRa, kutentha kwa vulcanization ndi 180 ℃ ndipo nthawi yopangira vulcanization nthawi zambiri imakhala pakati pa mphindi 6-10. Pamene kuthamanga kwa nthunzi yodzaza ndi 152MPa, kutentha kwa vulcanization ndi 200 ℃ ndipo nthawi yopangira vulcanization nthawi zambiri imakhala pakati pa mphindi 1-3. Pamene kuthamanga kwa nthunzi yodzaza pang'onopang'ono kumawonjezeka, kutentha kwa vulcanization kumawonjezekanso pang'onopang'ono, pomwe nthawi yopangira vulcanization imachepa. Rabala ya polyethylene yokhala ndi chlorinated yomwe imachokera imakhala ndi kukana bwino kwa misozi.
