Izidingo zenqubo yokubumba umjovo we-TPE

I-TPE eluhlaza ingumkhiqizo ohambisana nemvelo, ongenabuthi futhi ophephile, onobunzima obuningi (0-95A), umbala omuhle kakhulu, ukuthinta okuthambile, ukumelana nesimo sezulu, ukumelana nokukhathala nokumelana nokushisa, ukusebenza okuhle kakhulu kokucubungula, asikho isidingo I-Vulcanized, futhi ingaphinda isetshenziswe ukuze kuncishiswe izindleko, ngakho-ke, izinto zokusetshenziswa ze-TPE zisetshenziswa kakhulu ekubunjweni komjovo, ukukhishwa, ukubunjwa kokushaywa, ukubumba nokunye ukucubungula. Ngakho-ke uyazi ukuthi yiziphi izidingo ze-ukubumba umjovoinqubo TPE izinto zokusetshenziswa? Ake sibone okulandelayo.

Izidingo zenqubo yokubumba umjovo we-TPE eluhlaza:

1. Sula impahla eluhlaza ye-TPE.

Ngokuvamile, uma kunezidingo eziqinile ebusweni bemikhiqizo ye-TPE, izinto zokusetshenziswa ze-TPE kufanele zomiswe ngaphambi kokubunjwa komjovo. Ngoba ekukhiqizweni kokubumba umjovo, izinto zokusetshenziswa ze-TPE ngokuvamile ziqukethe amazinga ahlukahlukene omswakamo kanye namanye ama-polymers anesisindo esiphansi samangqamuzana amaningi. Ngakho-ke, umthamo wamanzi wezinto zokusetshenziswa ze-TPE kufanele zikalwe kuqala, futhi lawo anamanzi amaningi kakhulu kufanele omiswe. Indlela yokomisa evamile ukusebenzisa indishi yokomisa ukuze yome ku-60℃ ~ 80℃ amahora angu-2. Enye indlela ukusebenzisa i-drying chamber hopper, engakwazi ukuhlinzeka ngokuqhubekayo impahla eshisayo eyomile emshinini wokubumba umjovo, okuzuzisa ukwenza umsebenzi ube lula, ukugcina ukuhlanzeka, ukuthuthukisa ikhwalithi, nokwandisa izinga lomjovo.

2. Zama ukugwema ukubumba komjovo wokushisa okuphezulu.

Ngaphansi kwesisekelo sokuqinisekisa ikhwalithi ye-plasticization, izinga lokushisa le-extrusion kufanele lincishiswe ngangokunokwenzeka, futhi ukucindezela komjovo kanye nesivinini sesikulufa kufanele kunyuswe ukuze kuncishiswe i-viscosity yokuncibilika futhi kuthuthukiswe uketshezi.

3. Setha izinga lokushisa elifanele lomjovo we-TPE.

Enqubweni yokubumba umjovo we-TPE izinto zokusetshenziswa, izinga lokushisa elijwayelekile lokusetha uhla lwendawo ngayinye yilo: umgqomo 160 ℃ kuya ku-210 ℃, umlomo wombhobho 180 ℃ kuya ku-230 ℃. Izinga lokushisa lesikhunta kufanele libe phezulu kunokushisa kwe-condensation yendawo yokubumba umjovo, ukuze kugwenywe imivimbo ebusweni bomkhiqizo kanye nokukhubazeka komjovo wokubumba iglue ebandayo, ngakho-ke izinga lokushisa lesikhunta kufanele lenziwe libe phakathi 30 ℃ futhi 40 ℃.

4. Ijubane lomjovo kufanele lisuke kancane liye ngokushesha.

Uma kungamazinga amaningana omjovo, isivinini sisuka kancane siye esivinini. Ngakho-ke, igesi ekubunjeni ikhishwa kalula. Uma ingaphakathi lomkhiqizo ligoqwe ngegesi (ukunwetshwa ngaphakathi), noma uma kukhona amazinyo, iqhinga alisebenzi, le ndlela ingalungiswa. Isivinini sokujova esimaphakathi kufanele sisetshenziswe ezinhlelweni ze-SBS. Kuhlelo lwe-SEBS, isivinini somjovo esiphezulu kufanele sisetshenziswe. Uma isikhunta sinesistimu yokukhipha umoya eyanele, ngisho nomjovo wesivinini esikhulu akudingeki ukhathazeke ngomoya ovaleleke.

5. Naka ukulawula izinga lokushisa lokucubungula.

Izinga lokushisa lokucubungula lezinto zokusetshenziswa ze-TPE cishe lingama-degree angu-200, futhi i-TPE ngeke imunce umswakama emoyeni ngesikhathi sokugcinwa, futhi ngokuvamile ayikho inqubo yokomisa edingekayo. Bhaka ekushiseni okuphezulu amahora angu-2 kuya kwangu-4. I-TPE ihlanganiswe i-ABS, AS, PS, PC, PP, PA nezinye izinto ezidingekayo kufanele zibhakwe futhi zibhakwe ku-80 degrees amahora angu-2 kuya kwangu-4.

Kafushane, yizidingo zenqubo yokubumba umjovo we-TPE. I-TPE eluhlaza iyimpahla esetshenziswa kakhulu ye-thermoplastic elastomer, engabunjwa iyodwa noma iboshwe ngokufudumeza nge-PP, PE, ABS, PC, PMMA, PBT nezinye izinto zokubumba umjovo wesibili, futhi impahla ingaphinda isetshenziswe. Iphephile futhi inobungani bemvelo, isivele isiyisizukulwane esisha sezinto ezithandwayo zenjoloba nepulasitiki.
