Kuyesa Kusunga Madzi kwa Hydroxypropyl Methyl Cellulose Ether

Vitamini ether ndizomwe zimagwiritsidwa ntchito kwambiri mumatope a ufa wouma. Hydroxypropyl methyl cellulose ether imagwira ntchito yofunika kwambiri mumatope a ufa wouma. Pambuyo pa ether ya cellulose mumatope ikasungunuka m'madzi, guluuyo amatsimikizika chifukwa cha ntchito yapamtunda. The coagulant zakuthupi mogwira ndi wogawana anagawira mu dongosolo, ndi hydroxypropyl methylcellulose ether, monga colloid zoteteza, "kukulunga" tinthu olimba ndi kupanga wosanjikiza lubricating filimu pamwamba pake, kupanga matope dongosolo khola komanso Kupititsa patsogolo fluidity ya matope panthawi yosakaniza ndi kusalala kwa zomangamanga.

Chifukwa cha mawonekedwe ake a mamolekyu, njira ya cellulose ether imapangitsa kuti madzi a mumatope asakhale osavuta kutaya, ndipo pang'onopang'ono amawamasula kwa nthawi yaitali, ndikupangitsa kuti matope azikhala ndi madzi abwino osungira komanso ogwira ntchito. Kusungidwa kwamadzi kwa hydroxypropyl methyl cellulose ether: Ndilo chizindikiro chofunikira kwambiri komanso chofunikira. Kusungidwa kwa madzi kumatanthauza kuchuluka kwa madzi omwe matope osakanikirana amatha kusunga pambuyo pa capillary action pamunsi woyamwa. Mayesero otsatirawa a kasungidwe ka madzi a cellulose ether akufotokozedwa mwachidule kuti tikambirane.

Njira ya vacuum

Panthawi yoyesera, lembani nsonga ya Buchner ndi matope osakanizidwa ndi madzi, ikani pa botolo la fyuluta yoyamwa, yambani pampu ya vacuum, ndikuchita kusefera kwa mphindi 20 mopanikizika ndi (400 ± 5) mm Hg. Ndiye, malinga ndi kuchuluka kwa madzi mu slurry pamaso ndi pambuyo suction kusefera, kuwerengera madzi posungira mlingo motere.

fyuluta pepala njira

Kusungidwa kwamadzi kwa cellulose ether kumayesedwa ndi kuyamwa kwamadzi kwa pepala losefera. Zimapangidwa ndi nkhungu yoyesera mphete yachitsulo yokhala ndi kutalika kwina, pepala losefera ndi mbale yothandizira magalasi. Pali zigawo 6 za pepala losefera pansi pa nkhungu yoyesera, yomwe gawo loyamba ndi pepala lofulumira la fyuluta, ndipo zigawo zina 5 ndi pepala la fyuluta. Gwiritsani ntchito moyenera kuti muyese kulemera kwa mphasa ndi zigawo 5 za pepala lapang'onopang'ono la fyuluta, kutsanulira matope mu nkhungu yoyesera mutatha kusakaniza ndikupukuta, ndikuyiyika kwa mphindi 15: kenaka yezani kulemera kwa phale ndi zigawo 5 za kulemera kwa pepala loyenda pang'onopang'ono.
