Hydroxypylllulose, omwe amadziwika kuti HPMC, ndi yogwiritsidwa ntchito kwambiri popanga zomanga, makamaka ufa. Imagwira ntchito ngati thiccener, Bander ndi emulsifier. HPMC ndi yowonjezera bwino yomwe imatha kukonza magwiridwe antchito komanso kugwirira ntchito ufa. Monga zowonjezera zina zilizonse zowonjezera, hpmc zili ndi zovuta zake. Komabe, mavutowa atha kuyankhulidwa ndi machitidwe abwino ndikupanga mosamala.
Vuto 1: Sititha Kubalalika
Nthawi zina HPMC imabalalika bwino mu ufa wa punty, ndikupanga zotupa kapena ophatikizidwa omwe ndi ovuta kusungunuka. Vutoli limabweretsa kufanana pakati pa chomaliza, zomwe zimapangitsa kuti mufulunsi, mphamvu zochepa, komanso kusachita bwino.
Yankho: Njira zabwino zotsimikizira kuti HPMC imabalalika kwathunthu mu ufa wa putty ndikusakaniza koyamba ndi madzi kenako ndikuwonjezera kusakaniza kotsiriza. Ma ratios osakaniza ayenera kugwiritsidwa ntchito potsimikizira kusakaniza kwa HPMC. Kuphatikiza apo, kugwiritsa ntchito zida zosakanikirana kwambiri kumathandizira kuwononga zowonjezera za HPMC.
Vuto Lachiwiri: Kusunga kwamadzi
Chimodzi mwabwino kugwiritsa ntchito HPMC mu punty ufa ndi kuthekera kwake kukonza madzi. Komabe, izi ndi zothandiza ngati HPMC imapangidwa molondola ndikugwiritsa ntchito mulingo woyenera. Kusungidwa kwamadzi osavomerezeka kumatha kubweretsa magwiridwe antchito osagwirizana, kumapangitsa kuti nthaka ikhale ndi mphamvu.
Njira yothetsera HPMC mu punty ufa ziyenera kuthandizidwa kuti mukwaniritse zabwino. Mlingo woyenera wa HPMC ndi 0.3-0.5% ya kulemera kwathunthu kwa ufa. Kugwiritsa ntchito zoposa kuchuluka kwa magawo omwe amalimbikitsidwa sikutanthauza kusintha chitetezo chamadzi koma kumatha kuchepetsedwa ndi zokolola zochepa.
Vuto Lachitatu: Kuchedwa Kuyanika Nthawi
Mafuta a putety amagwiritsa ntchito hpmc nthawi zina amatenga nthawi yayitali kuti aletse kuposa momwe amayembekezeredwa, kupanga ndi kumaliza ntchito yovuta. Vutoli nthawi zambiri limachitika nthawi yonyowa komanso yozizira, koma imathanso kuchitika chifukwa chosalakwika.
Yankho: Njira zabwino zothetsera vutoli ndikuwonjezera mpweya wabwino komanso mpweya womanga pomanga kuti ufulumitse kupukuta. Komabe, nyengo yozizira, pogwiritsa ntchito chotenthetsera kapena gwero lina limatha kuthandiza kuthamanga kopuma. Ndikofunikanso kuwonetsetsa kuti mukugwiritsa ntchito chiwerengero cholondola cha madzi kuti musungunuke ufa, chifukwa madzi ochulukirapo amatha kuyambitsa nthawi zowuma.
Vuto 4: Moyo Wofupikitsa
HPMC imatha kukula kwa tizilombo, makamaka m'malo otentha komanso chinyezi, chomwe chingapangitse kuti alume a ptty ufa. Kukula kwa microsi yaying'ono kumatha kupereka mankhwala osatulutsa, zomwe zimapangitsa kuti zigwirizane ndi ndalama zobwezeretsa.
Yankho: Kusungidwa koyenera kwa HPMC ndikofunikira kuti muwonetsetse moyo wake wautali. Iyenera kusungidwa m'malo ozizira, owuma kuti muchepetse chinyezi. Kuphatikiza apo, kugwiritsa ntchito zoteteza ndi fungicides kumathandizira kuletsa kuchepa kwa microbies ndikulimbikitsa alumali wa putty ufa.
VUTO 5: Zovuta Zovuta Zida
Zovala zomwe zili ndi HPMC zimatsatira mawonekedwe ndi zida, zomwe zimatha kupanga zida zovuta komanso zowononga.
Yankho: Ikani Kutulutsa Kwa Othandizira ku chida musanayambe kugwiritsa ntchito kuti muchepetse kukhazikika pa chida. Kuphatikiza apo, kugwiritsa ntchito masitepe ambiri kumatha kuthandizira kuchotsa zowonjezera pamanja ndi mawonekedwe.
Kugwiritsa ntchito HPMC mu punty ufa kumakhala ndi zabwino zambiri zakulimbikitsidwa, kukonza magwiridwe antchito komanso kugwirira ntchito. Komabe, kuti mupindule mapindu ake, mabungwe omwe angabuke pakupanga ndi kugwiritsa ntchito ayenera kudziwika. Mayankho omwe afotokozedwa mu nkhaniyi amatha kuthetsa mavuto awa ndikuchepetsa zoopsa kuti atsimikizire bwino kugwiritsa ntchito ufa wa punty.
