Ezinye izinkinga mayelana ne-polyethylene e-chlorine:

I-polyethylene ene-chlorine (CPE) iyinto ye-polymer egcwele enokubukeka kwempuphu emhlophe, ayinabo ubuthi futhi ayinaphunga. Inokumelana okuhle kakhulu nesimo sezulu, ukumelana ne-ozone, ukumelana namakhemikhali, kanye nokumelana nokuguga, kanye nokumelana okuhle kwamafutha, ukubambezeleka komlilo, kanye nezakhiwo zokufaka imibala. Ukuqina okuhle (kusaguquguquka ku--30 ℃), ukuhambisana okuhle nezinye izinto ze-polymer, izinga lokushisa eliphezulu lokubola, ukubola kukhiqiza i-HCL, engakhuthaza ukusabela kwe-CPE kokususwa kwe-chlorine.

Indlela yamanzi ye-polyethylene ene-chlorine ivame ukusetshenziswa, enezindleko eziphansi zokukhiqiza kanye nokungcola okubi. Enye indlela yindlela yokumiswa, evuthiwe. Ezasekhaya zingathuthukiswa futhi zisetshenziswe ngentuthuko esheshayo, futhi isivinini sokomisa siyashesha. Ivame ukusetshenziswa emathangini okugcina izinto kanye nezakhiwo zensimbi ukuthuthukisa ukuphepha kokwakha.

Amamodeli e-polyethylene e-chlorine (CPE) asekhaya ngokuvamile abonakala ngezinombolo ezifana no-135A, 140B, njll. Izinombolo zokuqala 1 no-2 zimelela i-crystallinity eseleyo (inani le-TAC), 1 imelela inani le-TAC eliphakathi kuka-0 no-10%, 2 imelela inani le-TAC>10%, izinombolo zesibili nezesithathu zimelela okuqukethwe kwe-chlorine, isibonelo, 35 imelela okuqukethwe kwe-chlorine okungu-35%, kanti inombolo yokugcina yinhlamvu ethi ABC, esetshenziselwa ukukhombisa isisindo sama-molecule se-PE yezinto zokusetshenziswa. U-A mkhulu kunabo bonke kanti u-C mkhulu kunabo bonke.

Ithonya lesisindo sama-molecule: I-polyethylene e-chlorinated (CPE) inesisindo sama-molecule esiphezulu kanye ne-viscosity ephezulu yokuncibilika ezintweni zayo zohlobo lwe-A. I-viscosity yayo ifana kakhulu ne-PVC futhi inomphumela omuhle kakhulu wokuhlakazeka ku-PVC, yakha inethiwekhi efanelekile efana nokuhlakazeka. Ngakho-ke, izinto zohlobo lwe-A ze-CPE ngokuvamile zikhethwa njenge-modifier ye-PVC.

Isetshenziswa kakhulu: ucingo kanye nekhebula (izintambo zemayini yamalahle, izintambo ezichazwe ezindinganisweni ze-UL kanye ne-VDE), ipayipi le-hydraulic, ipayipi lemoto, i-tape, ipuleti lerabha, ukuguqulwa kwepayipi lephrofayili ye-PVC, izinto ezisebenza ngogesi, ukuguqulwa kwe-ABS, njalo njalo. Ikakhulukazi ukuthuthukiswa kwemboni yezintambo kanye nekhebula kanye nemboni yokukhiqiza izingxenye zezimoto kuye kwabangela isidingo sokusetshenziswa kwe-CPE esekelwe ngerabha. I-CPE esekelwe ngerabha iyirabha ekhethekile yokwenziwa enomsebenzi omuhle kakhulu, ukumelana nokushisa nokuguga kwe-oxygen kanye ne-ozone, kanye nokulinda komlilo okuhle kakhulu.

Izici ezithinta izinga lokushisa lokubola kokushisa kwe-CPE

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

Kuhlobene nobumsulwa. Ukususwa okunganele kwama-initiator, ama-catalyst, ama-acid, izisekelo, njll. okungeziwe ngesikhathi senqubo yokwenza i-polymerization, noma ukumuncwa kwamanzi ngesikhathi sokugcina nokuthuthwa, kunganciphisa ukuzinza kwe-polymer. Lezi zinto zingabangela ukusabela kokuwohloka kwama-ion ama-molecule, kanti i-CPE iqukethe izinto ezinesisindo esiphansi sama-molecule njenge-Cl2 ne-HCl, ezingasheshisa ukubola kokushisa kwe-resin;
