Sib tov
Piv rau cov qauv ib txwm ntawm chloroprene roj hmab. Chlorinated polyethylene tsis xav tau plasticization thiab tsis xav tau khaws cia tom qab plasticization. Cov kua dej ntxiv hauv cov mis chlorinated polyethylene tuaj yeem sib xyaw thiab nqus nrog lwm cov hmoov thaum lub sijhawm batching, uas tuaj yeem zam kev ntxuav thiab ntws thaum lub sijhawm sib tov tiag tiag. Qhov kub ntawm vulcanization ntawm chlorinated polyethylene yuav tsum tshaj 160 ℃ Kev tsim khoom tas mus li tuaj yeem ua tiav hauv qab lub hauv paus ntawm dej txias, tab sis qhov kub feem ntau tsis tshaj 160 ℃. Yog li, tus neeg sawv cev sulfurizing siv hauv chlorinated polyethylene yuav tsum tsis txhob ntxiv cais ntawm lwm cov khoom ntxiv, thiab tuaj yeem sib xyaw ncaj qha nrog lwm cov hmoov. Cov kev xav tau kub sib tov rau chlorinated polyethylene yog qhov dav heev. Thaum qhov kub yog ntawm 40 ℃ thiab 120 ℃, yuav tsis muaj kev lo lossis hlawv ntawm cov menyuam. Thaum siv lub tshuab sib tov qhib, nws yog qhov tsim nyog los tua dej txias lossis tig rau ntawm lub pa dej raws sijhawm. Vim tias cov polyethylene chlorinated tsim cov cua sov ntau vim yog kev sib txhuam thaum lub sijhawm sib tov, nws yog qhov tsim nyog ntxiv dej txias txaus thaum sib tov hauv lub tshuab sib tov sab hauv. Qhov kub ntawm kev faib tawm feem ntau yog nruab nrab ntawm 110 ° C thiab 120 ° C Qhov no tso cai rau kev sib tov ntau yam tsis muaj kev cuam tshuam tsis zoo rau qhov zoo ntawm cov polyethylene chlorinated.
Kev Khaws Cia thiab Kev Kho Kom Kub
Piv rau cov roj hmab fluoroprene, cov roj hmab sib xyaw chlorinated polyethylene muaj kev ruaj khov zoo dua thiab tsis xav tau qhov kub qis. Cov av noo siab thaum lub caij ntuj sov tsis muaj kev cuam tshuam ncaj qha rau nws. Chlorinated polyethylene tsis xav tau dej txias thaum lub sijhawm ua kom sov, thiab qhov kub feem ntau yuav tsum siab dua 50 ℃.
Ua cov sheaths tiv thaiv rau cov xov hlau thiab cables
Feem ntau, cov chlorinated polyethylene siv tau rau hauv kev tsim cov hlau thiab cov hlua khi siv cov extruders ntev lossis cov extruders luv luv. Feem ntau, cov hlau thiab cov hlua khi ua los ntawm cov extruders ntev yuav ci dua thiab tiav dua. Thaum extruding chlorinated polyethylene nplaum, qhov kub ntawm lub taub hau feem ntau yog nruab nrab ntawm 6 ℃ thiab 90 ℃. Vim muaj kev sib txhuam kub heev thaum lub sijhawm ua kom cov chlorinated polyethylene, qhov kub hauv cov roj hmab yuav siab dua, feem ntau ntawm 90 ℃ thiab 120 ℃. Yog li ntawd, thaum siv cov extruder ntev, nws yog qhov tsim nyog los saib xyuas thiab tswj qhov kub thiab txias kom zoo kom tsis txhob hlawv cov roj hmab.
Cov txheej txheem sulfurization
Piv nrog rau lwm hom roj hmab uas siv ntau, qhov kub thiab txias uas xav tau rau AC vulcanization txheej txheem ntawm chlorinated polyethylene yog qhov siab heev, feem ntau ntawm 160 ℃ thiab 180 ℃ Cov kev xav tau vulcanization rau chlorinated polyethylene hlau thiab cable sheath roj hmab yog: thaum nws lub siab vapor saturated yog 054 MPa, qhov kub vulcanization yog 160 ℃, thiab lub sijhawm vulcanization feem ntau yog 25 feeb-30 feeb Thaum lub siab vapor saturation yog 098MFRa, qhov kub vulcanization yog 180 ℃ thiab lub sijhawm vulcanization feem ntau yog 6mir-10 feeb. Thaum lub siab vapor saturation yog 152MPa, qhov kub vulcanization yog 200 ℃ thiab lub sijhawm vulcanization feem ntau yog 1mir-3 feeb. Raws li lub siab vapor saturation maj mam nce, qhov kub vulcanization kuj maj mam nce, thaum lub sijhawm vulcanization txo qis. Cov roj hmab chlorinated polyethylene uas tshwm sim muaj lub zog tensile zoo dua.
