Chidwi chaHpmcHydroxypropyl methl cellulose, yabwinoko yosungitsa madzi. Makulidwe ndi gawo lofunikira la hpmc. Pakadali pano, opanga anzawo osiyanirana amagwiritsa ntchito njira zosiyanasiyana kuti adziwe mafayilo a HPMC. Njira zazikuluzikulu zikusilira Rotovisko, Hudler, Ulonda wa Ulonda ndi Brookfield, etc.
Pazomwezo, zotsatira za ufa zimayesedwa ndi njira zosiyanasiyana ndizosiyana kwambiri, zina ndizosiyana ngakhale zingapo. Chifukwa chake, poyerekeza mawonekedwe, ziyenera kuchitika pakati pa njira yoyeserera yomweyi, kuphatikiza kutentha, rotor, etc.
Kwa kukula kwa tinthu tating'onoting'ono, ndikulimbikitsa tinthu tambiri, kukonzanso kwamadzi. Tinthu tating'onoting'ono tomwe timakumana ndi ma cellulose tomwe timakumana ndi madzi, pomwepo zimasungunuka ndikukulunga kwa mamolekyudwe amadzi kuti asungunuke, nthawi zina mapangidwe a matope am'madzi kapena abglomerate. Kusungunuka kwa cellulose ether ndi imodzi mwazinthu zomwe zimasankha ma ether ether. Ubwino ndi mndandanda wofunikira wa methyl cellulose ether. MC ya matope owuma imafuna ufa, madzi ochepa, komanso kukoma kwa 20% ~ 60% tinthu tambiri tochepa 63um. Ubwino umakhudza kusungunuka kwaHpmcHydroxypropyl methl cellulose ether. Kuchulukitsa kwamitundu nthawi zambiri kumatha kusungunuka mosavuta m'madzi popanda kusinthika, koma liwiro lophweka ndilocheperako, kotero sioyenera kugwiritsa ntchito matope owuma. Mu matope owuma, MC imabalalitsidwa pakati pa ophatikizika, mafayilo abwino ndi mafayilo ophatikizira monga simenti, komanso ufa wokha womwe ndi wabwino kwambiri pakusakanikirana ndi madzi. MC itawonjezera madzi kuti asungunuke a Auglomerate, ndizovuta kwambiri kubalalitsa ndikuwumbitsa. MC yokhala ndi chilengedwe chocheperako osati mahatchi okha, komanso amachepetsa mphamvu ya matope. Matope owuma ngati ouma akamangidwa m'dera lalikulu, liwiro la matope owuma limachepa kwambiri, lomwe limapangitsa kuwonongeka chifukwa cha nthawi yosiyanasiyana yothira nthawi yochepa. Kwa matope owombera matope, chifukwa cha nthawi yayifupi, kukoma kwake ndikokwera.
Nthawi zambiri, mafakiti apamwamba, abwinobwino amadzisungira madzi. Komabe, mafayilo apamwamba ali, olemera olemera a MC ndi, ndipo kusungunuka kofananira kudzachepa, komwe kumachepetsa kofananira, komwe kumakhudza mphamvu ndi matope omanga matope. Maonekedwe akuwoneka, zoonekeratu zotsatira zam'matambo, koma sizofanana ndi ubale. Maonekedwe ake, matope onyowa adzakhala omata kwambiri, ntchito yonseyi, magwiridwe antchito azomera ndi kutsatira kwambiri zapansi. Koma sikothandiza kuwonjezera mphamvu ya matope onyowa. Pakumanga, magwiridwe antchito a Anti-Anti-sag sizachidziwikire. Mosiyana ndi izi, ma viscciness pang'ono koma kusinthidwa methyl cellose celluse kukhala ndi luso labwino pokonzanso mphamvu ya matope onyowa.
Ma ether a cellulose amawonjezedwa ndi matope, magwiridwe antchito abwino, ma viscket, ma virus, magwiridwe antchito abwino.
Kuchita bwino kwa HPMC kumathandizanso pakusungidwa kwamadzi, nthawi zambiri amalankhula, chifukwa cha kusangalatsa kofanana ndi kukongola kwa meth ether ethel cell, zomwe zimalimbikitsa madzi ndibwino.
Kusunga kwamadzi kwa HPMC kumagwirizananso ndi kutentha kwa kugwiritsa ntchito, ndipo madzi osungira madzi a methyl cellulose ethel ether amachepetsa ndi kukwera kwa kutentha. Koma mu ntchito zenizeni, malo ambiri matope owuma adzakhala otentha kwambiri (okwera madigiri 40) pansi pa zomanga zam'madzi, zomwe nthawi zambiri zimathandizira kulimbitsa thupi, komwe nthawi zambiri zimathandizira kulimbikitsa kwa simenti ndi matope owuma. Kutsika kwa kuchuluka kwa malire kwamadzi kumadzetsa kumverera kowonekeratu komwe kungakhale koyenera komanso kusokonekera kumakhudzidwa. Munthawi imeneyi, kuchepetsa mphamvu ya kutentha kumakhala kotsutsa. Ngakhale owonjezera a methyl hydrothyl cellulose ethelose ether ether ether ether ether etherch etherch etherch etherction chitukuko chaukadaulo, kudalira kwake kumabweretsabe kufooketsa matope a matope owuma. Ngakhale ndi kuchuluka kwa methyl hydrothyl cellulose Mlingo (chiilimwe cha chilimwe), zomanga ndi kukana kukana sikukwaniritsa zosowa zogwiritsira ntchito. Mwa zina mwazinthu zapadera za MC, monga kuwonjezera kuchuluka kwa zolimbitsa thupi, madzi osungira madzi amatha kukhalabe ndi zotsatira zabwino kwambiri kutentha kwambiri, kotero kuti itha kupereka phindu la kutentha kwambiri, kuti ithe kupereka magwiridwe abwino kwambiri m'mikhalidwe yovuta.
