Ukuthengisa okushisayo kwe-YUEYANGUmshini Wokuhlanza I-Vacuum Stirring Defoaming-YY-JA50 (1L)ithunyelwe eqenjini elihamba phambili lamakhemikhali eBrazil ngoDisemba, 2025. Ihlinzeka ngosekelo lokuqinisekisa ikhwalithi yomkhiqizo, ukuzinzisa izinqubo zokukhiqiza, kanye nokuthuthukisa ukusebenza kahle kwale nkampani yeqembu.
Umshini Wokuxubha we-Vacuum we-YY-JA50(1L)Umsebenzi Oyinhloko kanye Nesimiso:
1. Susa amabhamuza ngempumelelo futhi ususe amaphutha omkhiqizo:
1) Ngesikhathi sokuxuba nokusabela kwezinto zokusetshenziswa ze-polyurethane, amagesi ancibilikisiwe, imikhiqizo yokusabela, kanye nama-bubble omoya alethwa ukuxutshwa ngomshini kuthambekele ekwakhekeni. Isici se-viscosity ephezulu senza kube nzima ukukhipha ama-bubble amancane (ngaphansi kuka-1μm). Ngemva kokuqina, la ma-bubble angaholela ezimbotsheni, ema-pinhole, kanye nasezimbotsheni ezinciphayo, okuholela ekuncipheni kwamandla, ukwehluleka kokuvala, kanye nokubukeka okubi.
2) I-vacuum defoaming mixer yehlisa izinga le-vacuum libe yi-10–30Pa (noma – izinga le-0.1MPa) ngokusebenzisa umgodi ovalwe. Amabhamuza akhula ngokushesha futhi abumbeke nge-polymer ngaphansi kwengcindezi engemihle. Uma ehlanganiswe nama-spiral blades, uhlobo lweplanethi, njll. ngesivinini esiphansi kuya kwesiphakathi (300–800r/min, noma ukuzizungeza kanye nokujikeleza ndawonye), amabhamuza ajulile ayasunduzelwa phezulu futhi akhishwe ukuze kugwenywe ukwakheka kwamabhamuza amasha ngesivinini esiphezulu. Izinga lokukhumula lingafinyelela ngaphezu kuka-99.5%, kususwe isici semigodi yomoya.
3) Ukukhishwa okuvaliwe okuhambisanayo kanye nokugcwalisa igesi okungenayo i-inert + ukukhululeka kwengcindezi ye-gradient kuvimbela ukuqhuma kwesibili ngemva kokukhipha i-foam futhi kuqinisekisa ukuzinza kwezinqubo ezilandelayo zokuthulula, ukuqhuma kwe-foam, njll.
2. Ukuxubana kwe-homogenization kuqinisekisa ukwakheka okuvumelanayo
1) Finyelela ukuhlanganiswa okufanayo kwezinga lama-molecule kwama-agent ayinhloko njenge-polyols nama-isocyanates anezithasiselo ezifana nama-pigment, ama-flame retardants, kanye nama-fillers, ukugwema ukushintshashintsha kokusebenza okubangelwa ukuphambuka kokuhlushwa kwendawo.
2) Umklamo wokuzijikeleza kweplanethi kanye nokujikeleza okuhambisanayo, ama-spiral blades + ukuklwebha udonga, njll. umboza sonke isitsha, uvimbela ukuhlukaniswa kanye nemvula, futhi ufanelekela izinto ezihlukile ze-viscosity (kusukela ku-prepolymer kuya kuma-elastomer ane-viscosity ephezulu), okuthuthukisa ukufana kanye nokuzinza kokusebenza komkhiqizo.
Umshini Wokuxubha we-Vacuum we-YY-JA50(1L)izici:
1) Uhlobo lwesikrini sokuthinta
2) Usayizi wendebe yokuxuba ungenziwa ngokwezifiso ngokuvumelana nezidingo zekhasimende ngenani lokuxuba.
3) Imodi yokusebenza: i-vacuum/ukujikeleza/uguquko/ukungasebenzisi ukuxhumana/imoto ephindwe kabili ongayikhetha)
4) Ukusetha i-vacuum: inkinobho ezimele/enomsebenzi wokulawula ukubambezeleka/ukusetha ngesandla
5). Umsebenzi wokuzihlola: isikhumbuzo se-alamu esizenzakalelayo sokungalingani ngokweqile
6) Ukuvikelwa kokuphepha: ukuyeka/ukusebenza okuzenzakalelayo kokukhiya/ukuvala isembozo okuzenzakalelayo
Isikhathi sokuthunyelwe: Disemba-26-2025
