Ezinye izingqinamba mayelana ne-chlorine polyethylene:

I-Chlorinated polyethylene (CPE) iyimpahla ye-polymer egcwele enokubukeka kwempushana emhlophe, engenabuthi futhi engenaphunga. Inokumelana nesimo sezulu esihle kakhulu, ukumelana ne-ozone, ukumelana namakhemikhali, nokumelana nokuguga, kanye nokumelana nowoyela okuhle, ukunqanda ilangabi, kanye nezakhiwo zombala. Ukuqina okuhle (kusaguquguquka ku--30 ℃), ukuhambisana kahle nezinye izinto ze-polymer, izinga lokushisa eliphezulu lokubola, ukubola kukhiqiza i-HCL, engabangela ukusabela kwe-dechlorination ye-CPE

Indlela enamanzi ye-polyethylene ene-chlorine ivame ukusetshenziswa, enezindleko eziphansi zokukhiqiza kanye nokungcola okubi. Enye indlela yindlela yokumiswa, esevuthiwe. Ezifuywayo zingathuthukiswa kanye nesicelo ngokuthuthuka okusheshayo, futhi isivinini sokumisa siyashesha. Kuvame ukusetshenziselwa amathangi okugcina kanye nezakhiwo zensimbi ukuthuthukisa ukuphepha kokwakhiwa.

Amamodeli asekhaya enziwe nge-chlorinated polyethylene (CPE) ngokuvamile abonakala ngezinombolo ezifana no-135A, 140B, njll. Amadijithi okuqala 1 no-2 amele i-residual crystallinity (inani le-TAC), u-1 umele inani le-TAC phakathi kuka-0 no-10%, u-2 umele i-TAC. inani>10%, izinombolo zesibili nezesithathu zimelela okuqukethwe kwe-chlorine, isibonelo, i-35 imele okuqukethwe kwe-chlorine engu-35%, futhi idijithi yokugcina uhlamvu ABC, olusetshenziselwa ukukhombisa isisindo samangqamuzana we-PE yempahla eluhlaza. U-A mkhulu futhi u-C mncane kakhulu.

Umthelela wesisindo samangqamuzana: I-Chlorinated polyethylene (CPE) inesisindo samangqamuzana esiphezulu kakhulu kanye ne-viscosity ephezulu encibilika ku-A-type yayo. I-viscosity yayo ihambisana kahle kakhulu ne-PVC futhi inomphumela omuhle kakhulu wokuhlakazeka ku-PVC, yakha inethiwekhi ekahle njengefomu lokuhlakazeka. Ngakho-ke, impahla ye-CPE yohlobo lwe-A ngokuvamile ikhethwa njengesilungisi se-PVC.

Ikakhulukazi esetshenziselwa: intambo nekhebula (izintambo zemayini yamalahle, izintambo ezichazwe kumazinga we-UL kanye ne-VDE), i-hydraulic hose, ipayipi yemoto, i-tape, ipuleti lerabha, ukuguqulwa kwepayipi lephrofayela ye-PVC, izinto kazibuthe, ukuguqulwa kwe-ABS, njalonjalo. Ikakhulukazi ukuthuthukiswa kwemboni yocingo nekhebula kanye nemboni yokukhiqiza izingxenye zezimoto kuqhubekisele phambili isidingo sokusetshenziswa kwe-CPE esekelwe enjoloba. I-CPE esekelwe ku-Rubber iyirabha yokwenziwa ekhethekile esebenza kahle kakhulu, imelana nokushisa ku-oxygen nokuguga kwe-ozone, kanye ne-flame retadancy enhle kakhulu.

Izinto ezithinta izinga lokushisa lokubola kwe-CPE

Izici ze-CPE ngokwayo zihlobene nokuqukethwe kwayo kwe-chlorine. Uma okuqukethwe kwe-chlorine kuphezulu, kulula ukubola;

Kuhlobene nobumsulwa. Ukususwa okunganele kwama-initiators, ama-catalysts, ama-acids, izisekelo, njll okwengezwe ngesikhathi senqubo ye-polymerization, noma ukumuncwa kwamanzi ngesikhathi sokugcina nokuthutha, kunganciphisa ukuzinza kwe-polymer. Lezi zinto zingabangela ukusabela kokuwohloka kwe-ion yamangqamuzana, futhi i-CPE iqukethe izinto ezinesisindo esiphansi kakhulu ze-molecular ezifana ne-Cl2 ne-HCl, ezingasheshisa ukubola okushisayo kwe-resin;
