Hpmc (hydroxypropyl methylcellulose) Chowonjezera chofunikira chomwe chimagwiritsidwa ntchito pomanga zinthu monga ufa, zomata, ndi zina zambiri monga kukula, kusungidwa kwamadzi, komanso kugwiritsa ntchito zomangamanga. Kupanga ufa wa putty, kuwonjezera kwa HPMC sikumangowonjezera kusungidwa kwamadzi kwa chinthucho, komanso kumawonjezera nthawi yake yomanga, kuletsa kutsuka kwakuti, kuletsa kutsuka kwakuti, kuletsa kutsuka kwamphamvu kwambiri pakumanga, ndikukhudza zomangamanga.
1. Sankhani njira yoyenera ya hpmc
Kuchita kwa HPMC kumagwirizana kwambiri ndi kunenepa kwake kwa ma molecular, hydroxypropyl, kuperekera methyl ndi zinthu zina. Pofuna kusintha kusungidwa kwamadzi kwa ufa, choyamba sankhani mtundu wa HPMC.
Kulemera kwambiri hpmc: hpmc yokhala ndi kulemera kwamphamvu kwambiri kumatha kupanga mawonekedwe amphamvu a network, omwe amathandizira kukonza madzi osungirako ufa ndi kuteteza madzi osakhalitsa. Nthawi zambiri, hpmc yokhala ndi mafayilo apamwamba azikhala ndi zotsatira zabwino pamagetsi osasunga madzi.
Mulingo woyenera wa zolowa m'malo: Mphamvu ya hydroxypyl ndi methyl kulower of Hopmc imakhudza kususuka kwake kusungunuka ndi kusagwiritsa ntchito madzi. Mulingo wapamwamba wa hydroxypropyl imathandizira kukonza hydrophilicity ya HPMC, potero imalimbikitsa magwiridwe ake osungira madzi.
Malinga ndi zofunikira za putty ufa, kusankha mtundu woyenera wa HPMC kumatha kusintha madzi osunga madzi a chinthucho.
2. Onjezani kuchuluka kwa HPMC yowonjezera
Pofuna kupititsa patsogolo kusungitsa kwamadzi kwa putty ufa, kuchuluka kwa HPMC yowonjezeredwa bwino. Powonjezera kuchuluka kwa HPMC, kugawa kwake kwamphamvu kumatha kukhala bwino komanso kusintha kwake kuchuluka kwake kungakhale kolimbikitsidwa.
Kuchulukitsa kuchuluka kwa kuphatikiza kumabweretsanso kuwonjezeka kwa ufa wa punty ufa. Chifukwa chake, ndikofunikira kuonetsetsa kuti madzi asungidwa bwino popewa ma vionection kwambiri kuti akhudze zomanga.
3..
Mapangidwe a kapangidwe kake kake amakhudza mwachindunji madzi. Kuphatikiza pa hpmc, kusankha kwa zinthu zina mu formula (monga ma mafilimu, zomatira, ndi zina) zimakhudzanso kusungidwa kwamadzi.
Zabwino ndi malo ena apamwamba: kukula kwa tinthu tating'onoting'onoOfferyo ali mu ufa putter adzakhudza ma adsorption yamadzi. Ufa wabwino ndi mafilimu okhala ndi malo apamwamba kwambiri amatha kuyamwa madzi ndi kuchepetsa kuchepa kwa madzi. Chifukwa chake, kusankha koyenera kathupi ndi chinthu chofunikira kwambiri pakukonza madzi.
Kusankhidwa kwa simenti Zosakaniza: Ngati putty ufa uli ndi simenti ndi zosakaniza zina, zomwe zimachitika simenti zitha kuwononga madzi. Chifukwa chake, ndikofunikira kukonzekeretsa kusungidwa kwamadzi kosasunthika mwa kusintha kuchuluka kwa simenti kuti affere.
4. Sinthani njira yosakanikirana
Njira yosakanikirana imakhudzanso zina pakusunga kwamadzi wa putty ufa. Kusakaniza koyenera kumatha kuthandiza obalalika kwathunthu ndikusakaniza mogwirizana ndi zosakaniza zina kuti mupewe kusakanitsidwa m'madzi chifukwa chosakanikirana.
Nthawi Yosakanikirana Yoyenerera: Ngati nthawi yosakanikirana ndi yochepa kwambiri, hpmc siyingakhale yosungunuka kwathunthu, yomwe ingakhudze magwiridwe ake a madzi. Ngati kuthamanga kosakanikirako kuli kwakukulu kwambiri, mpweya wambiri ungayambitsidwe, kukhudza ufa wa putty. Chifukwa chake, kuwongolera koyenera kwa kusakaniza kosakanikira kumathandizira kukonza madzi onse a putty ufa.
5. Kuwongolera chinyezi komanso kutentha
Kusunga kwamadzi kwa ufa sikungokhudzana ndi zopangira ndi formula, komanso zokhudzana kwambiri ndi chinyezi komanso kutentha kwa malo omanga. M'malo okhala ndi kutentha kwambiri komanso chinyezi chochepa, chinyezi cha putty ufa ndikosavuta kuwunika, kumapangitsa kuti zisaume mwachangu komanso zimakhudza zomangamanga.
Panthawi yomanga, kutentha komanso chinyezi ndi chinyezi kuyenera kusungidwa mokwanira kuti ufa ufa ukhale utaya madzi mwachangu kwambiri. Kuwongolera koyenera kwa kutentha kwa kutentha ndi chinyezi kumathanso kusintha madzi osungirako ufa.
6. Onjezani Mthandizi Wosunga Madzi
Kuphatikiza pa HPMC, othandizira ena osungitsa madzi amathanso kufunsidwa kuti adzawonjezeredwa kuti awonjezeredwa ku ufa, mowa wina wa polyvinyl amathanso kukonza madzi osungirako, komanso kupewa kuyanika mwachangu.
Komabe, powonjezeranso osunga madzi, ndikofunikira kulabadira kugwirizana kwawo ndi hpmc kuti musankhe zochita zina kapena kusokoneza ntchito yomanga.
7. Gwiritsani ntchito chinyezi cha chinyezi
Munthawi zina, ukadaulo wolamulira wolamulira ukhoza kugwiritsidwa ntchito popititsa patsogolo kusungitsa kwamadzi kwa putty ufa. Mwachitsanzo, kugwiritsa ntchito zitsulo zozikika zozikika zozikidwa m'madzi kapena chinyezi kumatha kuchepetsa kutayika kwa madzi pomanga, potero kumabweretsa nthawi yake yomanga ndikuwongolera nthawi yake yomanga.
Kusunga kwamadzi kwa ufa kungakhale bwino posankha mtundu woyenera waHpmc, Kuchulukitsa kuchuluka kwa kuwonjezera, kukonza njira yosakanikirana, kuwongolera chinyezi ndi kutentha kwa malo omanga, ndi njira zina. Monga gawo lofunikira la ufa wa putty, kusintha kwa madzi osungira kwa HPMC sikumangowonjezera luso lomangako, komanso kukonzanso bwino komanso kuchepetsa zofooka ndi mavuto pomanga. Chifukwa chake, kumvetsetsa ndi kunena zaluso njirazi kukonza madzi osungitsa madzi ndikofunikira kwambiri kwa mabizinesi omwe amabweretsa ndikugwiritsa ntchito ufa.
