Injoloba kanye nemikhiqizo yayo ekucubunguleni, ekugcinweni nasekusetshenzisweni, ngenxa yomphumela ohlangene wezici zangaphakathi nezangaphandle ezibangelwa ukuwohloka kancane kancane kwezakhiwo zenjoloba ezingokomzimba namakhemikhali kanye nezakhiwo zemishini, futhi ekugcineni zilahlekelwe inani lokusetshenziswa, lolu shintsho lubizwa ngokuthi ukuguga kwenjoloba. Ngaphezulu, liyaqhekeka, liyanamathela, liqina, lithambe, libe yimpuphu, lishintshe umbala, libe nesikhutha.

I-PVC eqinile ingenye yezinto ezisetshenziswa kakhulu zepulasitiki. Izinto ze-PVC ziyi-amorphous material.
Izinto ze-PVC zivame ukungezwa ekusetshenzisweni kwangempela kwama-stabilizers, izinto zokuthambisa, ama-axiliary processing agents, imibala, ama-ejenti womthelela nezinye izithasiselo.
Impahla ye-PVC inokungashi, amandla aphezulu, ukumelana nesimo sezulu kanye nokuzinza okuhle kakhulu kwejometri.
I-PVC inokumelana okuqinile nama-oxidants, ama-ejenti anciphisayo nama-asidi aqinile. Kodwa-ke, ingagqwala ngama-acid oxidizing agxilile njenge-concentrated sulfuric acid, i-nitric acid egxilile futhi ayifanele ukuthintana nama-hydrocarbon anephunga elimnandi nama-hydrocarbon ane-chlorinated.

Uhlobo lwe-anti-corrosion coating luyi-richand inkambu yayo yesicelo nayo icebile kakhulu.Ngakho-ke uma isetshenziswa emikhakheni ehlukene, kungenzeka ukuthi ukhethe uhlobo lokugqoka alufani. Iphayiphi le-polyethylene ephezulu ene-chlorine evikela ukubola ingenye yekilasi le-polyethylene resin ephezulu njenge-anticorrosive base material, ene-resin eguquliwe, i-plasticizer, i-rust pigments, izinyibilikisi kanye nezithasiselo ezakhiwe ingxenye eyodwa evikela ukubola.

Irabha ephulukisiwe iyinkinga evame kakhulu ohlelweni lokukhiqiza ikhebula le-polyethylene eline-chlorine, futhi lesi simo sibonakala kakhulu ehlobo. Izici ezinomthelela ukushisa kwe-extrusion, umfutho we-steam, isikhathi se-coke sokuxuba irabha, kanye nokuxutshwa kokungcola.

I-Chlorinated polyethylene isenezici ezithile zamapulasitiki, futhi uma isetshenziselwa ukukhishwa kwekhebula, isadinga izinga lokushisa eliphakeme le-plasticizing kunerabha yendabuko. Kumakhasimende angaziqondi izici ze-CPE, uma engabambi imingcele yenqubo efanele futhi alandele inqubo yendabuko ye-rubber extrusion ukukhiqiza izintambo, izinkinga ezifana nokushisa okuphansi kakhulu kanye ne-plasticization embi zizokwenzeka.

I-Chlorinated polyethylene iyimpuphu, kulula ukumunca umswakama isikhathi eside, okuholela emswakama owedlulele, ukuze imikhiqizo ibe nama-bubbles noma ama-micropores, njll., isimo sezulu esishisayo esiseningizimu kungenzeka sibe nalesi simo. Ngaphezu kwalokho, ukukhiqizwa kwezintambo zenjoloba kuyinkimbinkimbi kunaleyo yezintambo zepulasitiki, ezithintekayo yizici eziningi ezifana nezimo zemishini, izimo zenqubo, izinga lokusebenza, izinga lobuchwepheshe, njll., kunezinkinga eziningi ohlelweni lwe-extrusion, futhi akulula ukuxazulula kahle.

I-rutile titanium dioxide kanye ne-anatase titanium dioxide yizinhlobo ezimbili ezibalulekile ze-titanium dioxide, okwamanje ezisetshenziswa kakhulu emakethe, kodwa izakhiwo zazo zombili zihluke kakhulu.

I-ACR iyisiguquli somthelela esingcono kakhulu esisebenza kahle kukonke, ukusebenza kahle kokucubungula kwe-PVC eguquliwe, amandla aqine kakhulu, imodulus, izinga lokushisa lokushintsha okushisayo, nokumelana nesimo sezulu esihle kakhulu. Ngaphezu kokumelana nesimo sezulu esingesihle, i-MBS iphinde ibe isiguquli somthelela se-PVC esisebenza kahle kukonke, ikakhulukazi i-MBS inenkomba ye-refractive efana ne-PVC, futhi iyona kuphela isilungisi somthelela esisetshenziselwa ukucutshungulwa komthelela obonakalayo oguquliwe wemikhiqizo ye-PVC.
