1, Izinto ezintathu eziphambili ezichaphazela ukusebenza kweCPE
Okokuqala, luhlobo lweCPE esetyenziswayo. I-CPE efunyenwe kwi-polyethylene ye-molecular weight high ine-viscosity ephezulu kunye namandla okuqina, kodwa ukunamathela phakathi kwale CPE kunye ne-PVC resin iphantsi. I-CPE efunyenwe kwi-polyethylene ephantsi yobunzima bemolekyuli ine-viscosity ephantsi kunye namandla okuqina, kwaye i-CPE efunyenwe kwi-high-density polyethylene inokumelana nobushushu obuhle.
Okwesibini, bubukhulu bamasuntswana ezinto ezikrwada. Xa ubukhulu be-particle buncinci, kulula ukwenza i-jelly okanye i-CPE edibeneyo, kwaye xa ubukhulu becala bukhulu kakhulu, ukuhanjiswa kweklorini akulingani.
Kwakhona, linqanaba le-CPE chlorination. Xa umxholo weklorini ungaphantsi kwe-25%, unokungahambisani kakuhle ne-PVC kwaye ayikwazi ukusetyenziswa njengesilungisi; Xa umxholo we-chlorine ukhulu kune-40%, unokuhambelana kakuhle ne-PVC kwaye ingasetyenziselwa njengeplastiki eqinile, engafanelekanga njengenguqu yempembelelo; I-CPE enomxholo weklorini ye-36-38% ine-elasticity enhle kunye nokuhambelana ne-PVC, okwenza ukuba isetyenziswe ngokubanzi njengenguqu yempembelelo ye-PVC. Okwangoku, i-CPE enomxholo we-chlorine we-35% isetyenziswa ngokuqhelekileyo. I-CPE enomxholo weklorini ojikeleze i-35% inekristale ephantsi kunye nobushushu beglasi yokutshintsha, ukuqina okuhle kwerabha, kunye nokuhambelana okufanelekileyo kunye nePVC. Isetyenziswa ngokubanzi njengesilungisi sempembelelo kwiimveliso ezinzima zePVC.
2, Isiphumo CPE Ukongeza kwi PVC
Xa isixa esongezelelweyo singaphantsi kwemizuzu eyi-10, amandla empembelelo ye-PVC akhula ngokukhawuleza kunye nokongezwa kwe-CPE, kodwa ukunyusa ukongezwa kwe-CPE kubangela ukuphuculwa okuncinci kumandla empembelelo ye-PVC. Ngoko ke, njenge-arhente exhathisa impembelelo, inani elifanelekileyo le-CPE eliza kongezwa li-8-10. Njengoko i-CPE isanda, amandla okuqina engxubevange ye-PVC ayaqhubeka ehla, ngelixa ubude bekhefu bukhula. Ukuba ukuqina kubonakaliswa njengemveliso yamandla okuqina kunye nobude ngexesha lekhefu, kuyacaca ukuba ukuqina kwePVC kuya kwanda kakhulu ngokunyuka kweCPE.
