1. Izinto ezintathu eziphambili ezichaphazela ukusebenza kwe-CPE
Okokuqala, luhlobo lwe-CPE esetyenziswayo. I-CPE efunyenwe kwi-polyethylene enobunzima obuphezulu beemolekyuli inoburhabaxa obukhulu kunye namandla okutsalwa, kodwa ukunamathelana phakathi kwale CPE kunye ne-resin yePVC kuphantsi. I-CPE efunyenwe kwi-polyethylene enobunzima obuphantsi beemolekyuli inoburhabaxa obuphantsi kunye namandla okutsalwa, kwaye i-CPE efunyenwe kwi-polyethylene enobunzima obuphezulu inokumelana okuhle nobushushu.
Okwesibini, bubungakanani beesuntswana zezinto eziluhlaza. Xa ubukhulu beesuntswana buncinci kakhulu, kulula ukwenza ijeli okanye i-CPE edibeneyo, kwaye xa ubukhulu beesuntswana bukhulu kakhulu, ukusasazwa kwe-chlorine akulunganga.
Kwakhona, linqanaba le-CPE chlorination. Xa umxholo we-chlorine ungaphantsi kwe-25%, awuhambelani kakuhle ne-PVC kwaye awunakusetyenziswa njengesiguquli; Xa umxholo we-chlorine ungaphezulu kwe-40%, uhambelana kakuhle ne-PVC kwaye ungasetyenziswa njenge-plasticizer eqinileyo, awufanelekanga njengohlengahlengisi wempembelelo; i-CPE enomxholo we-chlorine we-36-38% inokuguquguquka okuhle kwaye ihambelana kakuhle ne-PVC, nto leyo eyenza ukuba isetyenziswe kakhulu njengohlengahlengisi wempembelelo ye-PVC. Okwangoku, i-CPE enomxholo we-chlorine we-35% isetyenziswa rhoqo. I-CPE enomxholo we-chlorine we-35% ine-crystallinity ephantsi kunye nobushushu bokutshintsha kweglasi, i-raber elasticity elungileyo, kwaye ihambelana kakuhle ne-PVC. Isetyenziswa kakhulu njengohlengahlengisi wempembelelo kwiimveliso eziqinileyo ze-PVC.
2, Isiphumo Sokongezwa kweCPE kwiPVC
Xa isixa sokongeza singaphantsi kwemizuzu eli-10, amandla oxinzelelo lwe-PVC ayanda ngokukhawuleza xa kongezwa i-CPE, kodwa ukonyusa isixa sokongeza se-CPE kubangela ukuphucuka okuncinci kwamandla oxinzelelo lwe-PVC. Ke ngoko, njengearhente enganyangekiyo, isixa esifanelekileyo se-CPE esongezwayo simalunga ne-8-10. Njengoko i-CPE isanda, amandla oxinzelelo lwee-PVC blends ayaqhubeka ehla, ngelixa ulwando xa kuqhekeka lusanda. Ukuba ukuqina kubonakaliswa njengemveliso yamandla oxinzelelo kunye nolwando xa kuqhekeka, kuyacaca ukuba ukuqina kwe-PVC kuya kwanda kakhulu xa kongezwa i-CPE.
