Isimo sokuthuthuka kobuchwepheshe bokukhiqiza i-HPMC kanye nenqubo ye-hydroxypropyllylylylylylylylylylylylylyll methyl celtulose eChina

I-Hydroxypropyll methyl cellulose hpmcKumkhiqizo wamanje wasekhaya unikezwa kuqala ngokweqiniso ngokweqiniso ubuchwepheshe bendlela yendlela, lobu buchwepheshe bumelwe yi-WUXI Chempliom Ikhanjini Yokuphendula Indlela yokuphendula, ngoba imishini ye-liquid Christian Reaction reaction reaction, impumelelo yesigaba sokuphendula esisezingeni eliphakeme se-etherification reaction, abakhiqizi be-ether.

Ukukhiqizwa kwe-Hydroxyproppropyllylylylylylylylyllylylylylcm Inqubo yokuhlanza isebenzisa inqubo esezingeni eliphakathi lapho i-organic solvent isuswa khona kwi-reactor kanti umkhiqizo ongcolile uhlanzwa ngokusebenzisa ama-washes ambalwa nokuphelelwa ngamanzi emanzini ahlanzekile kanye namasenti. Ukusebenza komkhiqizo okuqediwe nge-gransation ephakathi, ngaphansi kwesimo sokushisa (kukhona nomenzi ongenawo umgomo), ukomisa kanye nokuchoboza indlela ekhethekile nje, ukucubungula okukhethekile) ukucubungula kanye nokusabalalisa indlela yokusabalalisa.

Indlela yesigaba se-Liquid inezinzuzo ezilandelayo: Inqubo yokusabela inqubo yengcindezi yangaphakathi incane, izidingo zomthamo wokucindezela kwemishini zisezingeni eliphansi, elincane. Ngemuva kokufakwa e-ly, iselula kunwetshwe ngokuphelele futhi ngokulinganayo ULyle unokungenelela okungcono nokuvuvukala kweselula. I-ethesherification reactor incane, ihambisana nokuvuvukala okufanayo kwe-Alkali Cellulose, ngakho-ke ikhwalithi yomkhiqizo kulula ukuyilawula, ukufakwa esikhundleni kanye ne-viscosity kungatholwa imikhiqizo eyunifomu eminingi, izinhlobo futhi kulula ukuyifaka esikhundleni.

Kodwa-ke, le nqubo futhi inobunzima obulandelayo: I-reactor imvamisa ayiyona enkulu kakhulu, ukulinganiselwa kwezibalo kuholela ekukhiqizweni okuncane kokukhiqiza, ukuze kuthuthukiswe umphumela, kuyadingeka ukwandisa inani lama-reactors; Imikhiqizo ecwengekile futhi ehlanziwe idinga imishini eminingi, ukusebenza okuyinkimbinkimbi, ukuqina kwabasebenzi; Ngoba akukho anti-isikhutha kanye nokwelashwa okuhlanganisiwe, okuphumela ekuzitezeni umkhiqizo wokuqina kanye nezindleko zokukhiqiza zithintekile; Ukupakishwa nge-Manual Way, ukuqina kwabasebenzi, izindleko zabasebenzi abaphezulu; Izinga elizenzakalelayo lokulawula ukuphendula liphansi kunalokho kwenqubo yesigaba segesi, ngakho-ke ukunemba kokulawula kuphansi. Uma kuqhathaniswa nenqubo yesigaba segesi, izinhlelo eziyinkimbinkimbi ze-solvent zokubuyiselwa kwemali ziyadingeka.

Ngokwephuculwa kweHydroxyPropproppropyllyrlopylyrlopylylylylyrulose technology, amanye amabhizinisi ngokuqhubeka okusha, indlela enkulu yesigaba se-kettle ithuthukiswe ngokuxhuma kanye nezindlela zobuchwepheshe. I-Chemin Chemistry isebenzisa inqubo yokukhiqiza ye-HPMC yasekuqaleni, hhayi kuphela inqubo yokukhiqiza enengqondo, amapharamitha okulawulwa kokusebenza anembile futhi athembekile, ukusabalalisa okuphelele kokungavuthiwe, futhi ngesikhathi esiphelele ukuqiniseka, futhi ngasikhathi sinye ukuqinisekisa ukuqina kwekhwalithi yomkhiqizo. Umugqa wokukhiqiza we-HPMC wamanye amabhizinisi uguqulwe izinguquko ezenzakalelayo, ukufezekisa izidingo zokulawulwa kwe-DCS automation automation, okuqukethwe okuqinile kungasetshenziswa ukulinganisa ngokunemba, ngokuthembela, ukuqina, ukuqina, ukuqina, ukuqina, ukuqina, ukuqina okuthuthukile Manpower, kunciphisa ukuqina kwabasebenzi, kepha futhi kuthuthukisa indawo yokusebenza esizeni.
