Isisindo Esiphezulu Semolekyuli(Hmw) Umshini Wokukhipha Ibhuloho Lensimbi Eqinisiwe

1.Ithreyi lekhebula -聚合物lenziwe ngezinto - ezisezingeni eliphezulu -聚合物PVC kanye ne-ABS聚苯氧乙烯。Inezinzuzo zokumelana nokushisa okuqinile, i系数ephansi yokwanda okushisayo, ukugoba okuhle kwelangabi, ukusebenza okuphezulu kwe-insulation, ukumelana nokugqwala okuqinile nempilo ende yesevisi。Inezinzuzo ezinkulu kunemikhiqizo yendabuko。

2.Idizayini yokuthuthukisa yesakhiwo ithuthukisa ukguquguquka nokushesha kokufakwa kwethreyi lekhebula。Isakhiwo sethreyi yekhebula yendabuko siyinkimbinkimbi futhi sidinga izingxenye eziningi, kuyilapho ithreyi yekhebula yepulasitiki entsha ye-alloy ingahlangabezana kakhulu nezidingo zamakhasimende ngokusebenzisa inqwaba yezingxenye, okuthuthukisa kakhulu ukuguquguquka nokushesha kokufakwa kwethreyi yekhebula。

3.图图萨izinga lokusetshenziswa kwezinto -聚合物，ezingaba phezulu ngo-5% kunezivamile ngokuqinisekiswa。i -聚苯氧乙烯inezici ezivelele zemishini, ikakhulukazi amandla amahle okuqina, amandla omthelela, ukumelana nokugqwala kanye nokumelana nokukukhasa。Ngaphansi komthwalo we-21MPa we-3000h, inani lokukhuphuka liyi-0。75% kuphela, kuyilapho i-PC ingu-1% kanye ne-POM engu-2。3%， i-ABS 3%。Ngokuxuba ngokugcwele ne-PVC, izinga lokusebenzisa liyathuthukiswa, elingaphezu kka -5% ngaphezu kwalelo elivamile。

4.Umkhiqizo, umklamo, omuhle, wokubukeka, nokuhlobisa, okuphezulu。Umkhiqizo wenziwe ngezinto zepulasitiki ezinpulasitiki eqinile futhi zicutshungulwa ngokubunjwa komjovo nokubunjwa kwe-挤压。Inomklamo omuhle wokubukeka。Ngomklamo wokwenza kahle kwesakhiwo, ingahlanganiswa ngokungafanele futhi ibe nomhlobiso oqinile。Inqoba ukushiyeka kokubukeka kabi kanye nokusebenza komhlobiso ophansi wemikhiqizo yendabuko。

5.Impilo yesevisi yebhuloho le-polymer yinde kakulu。Uma kuqhathaniswa nebhuloho lensimbi lendabuko, impilo yesevisi iphindwe izikhathi ezinguo -5-8, kunciphisa izindleko zokutshala izimali zesibili zokushintsha ibhuloho。Imikhiqizo yebhuloho lensimbi yendabuko inokusebenza okungekuhle kwe-防腐，ngakho-ke ibhuloho kufanele lipendwe futhi lilungiswe njalo。Izindleko zempahla kanye nezindleko zabasebenzi ziphakeme, kuyilapho ibhuloho le-polymer linokumelana nokugqwala okuqinile, okunciphisa kakhulu Izindleko zokunakekelwa kanye nesikhathi sokulilungisa。Ithreyi yekhebula yepulasitiki ye-alloy ayidingi ukucishwa ngesikhathi sokulungiswa, futhi ukulahlekelwa okubangelwa ukuvala shaqa kokukhiqiza kuncipha ngokufanele, okuthuthukisa ngempumelelo ukusebenza kahle kokukhiqiza。
