1, Thuthukisa ukuqina kanye nokumelana nomthelela
Ukuthuthukisa ukuqina: I-CPE, njenge-elastomer, ithuthukisa ukuqina kwe-matrix ye-PVC ngokuxuba ngokomzimba, okuthuthukisa kakhulu amandla okuthinta kwezinto ezihlanganisiwe. Ukuhlolwa kubonise ukuthi ukwengeza izingxenye eziyi-10 ze-CPE kungandisa amandla okuthinta ezingxenye zepulasitiki zokhuni ze-PVC ezine-foam ngo-20%. I-Bontecn Group I-CPE ekhethekile yepulasitiki yokhuni yaseShayina ingathuthukisa kakhulu ukuqina komkhiqizo futhi inciphise izindleko zokukhiqiza. Siyakwamukela ukubuza.
Ukusebenza kahle kwezinga lokushisa eliphansi: Izinto zokuqinisa uchungechunge lwama-molecule eziguquguqukayo ze-CPE zithuthukisa ukuguquguquka kwazo ezindaweni ezisezingeni lokushisa eliphansi, zigwema ukuqhekeka kwezinga lokushisa eliphansi.
2, Thuthukisa ukusebenza kokucubungula kanye nokuhambisana
Ukuhlanganiswa okuthuthukisiwe kwe-interface: Imicu yezitshalo (njenge-cellulose) iqukethe inani elikhulu lamaqembu e-hydroxyl futhi ayihambisani kahle ne-PVC engathandi amanzi. Ama-athomu e-polar chlorine kanye nesakhiwo se-non-polar chain segment se-CPE asebenza “njengebhuloho” lokuthuthukisa ukunamathelana phakathi kwemicu ne-PVC, okunciphisa ukuhlukaniswa kwesigaba.
Lungiselela ukugeleza kokuncibilika: I-CPE inciphisa ukuthambekela kokuncibilika, inciphisa ukuwohloka kokugeleza kokucutshungulwa okubangelwa inani elikhulu lokugcwalisa i-powder yokhuni, futhi yenza ukuxuba nokubumba kwe-extrusion kube lula.
Ucwaningo lwe-rheological lubonisa ukuthi i-5 phr CPE ingakhuthaza ukwakheka kwejeli ye-PVC futhi yandise i-viscosity eyinkimbinkimbi ye-melt; Ezingxenyeni eziyi-10, i-viscosity incishiswa ukuze ilinganise ukusebenza kahle kokucubungula kanye nokusebenza.
3, Ukuthuthukiswa kwesici esisebenzayo
Ukuthuthukiswa kokuvinjelwa komlilo: Uma okuqukethwe kwe-chlorine ye-CPE kuphakeme (mhlawumbe ngo-36-38%), kulapho umphumela wokuvinjelwa komlilo ubaluleke khona. Ama-athomu ayo e-chlorine akhipha i-hydrogen chloride ngesikhathi sokusha ukuze avimbele ukusabalala komlilo.
Ukumelana nesimo sezulu kanye nokuqina: Isakhiwo sama-molecule agcwele se-CPE sinikeza izinto ezihlanganisiwe ukumelana okuhle kakhulu nokuguga, ukumelana ne-ozone, kanye nokumelana nokugqwala kwamakhemikhali, okwandisa impilo yazo yenkonzo yangaphandle.
4, Ukulawulwa okuphelele kwezakhiwo zemishini
Ibhalansi yamandla nokuqina: Inani elifanele le-CPE (izingxenye ezi-5-15) lingathuthukisa ukuqina ngenkathi ligcina amandla okuthamba, ukuqina, kanye nokumelana nokukhukhuleka kwezinto. Ukwengeza ngokweqile kungaholela ekwehleni kwamandla, okudingeka kulawulwe ngokusebenzisa ukulungiswa kwefomula.
5, Isifinyezo
I-CPE ixazulula izinkinga zobuthakathaka obukhulu, ukucubungula okunzima, kanye nokusha kwezinhlanganisela zepulasitiki zokhuni ze-PVC ngokusebenzisa indlela ephindwe kane yokuqinisa, ukuhambisana kwesikhombimsebenzisi, izinsiza zokucubungula, kanye nokuthuthukiswa kokusebenza, iba yi-modifier eyinhloko yentuthuko yazo yokusebenza okuphezulu. Ukukhetha i-CPE ngokulinganiselayo enokuqukethwe kwe-chlorine okungu-35-38% kanye nokwenza ngcono inani lokwengeza (ngokuvamile izingxenye ezingu-5-15) kungafinyelela ibhalansi phakathi kokusebenza kanye nezindleko.
