HydroxypropylmethylCelose (hpmc) ndi ether eleul yochokera ku zinthu zachilengedwe monga mtengo wamtengo wapatali komanso mabatire a thonje. Chifukwa cha malo ake apadera, kuphatikizapo kukhazikika kwa madzi, luso lakumwamba, lomwe limapangidwa ndi makanema, ndi zina zambiri. Chimodzi mwazinthu zofunika kuzilingalira mukamagwiritsa ntchito HPMC ndichakuti, chomwe chingakhudze momwe limagwirira ntchito m'malo osiyanasiyana ogwiritsira ntchito. Munkhaniyi, timakambiranani chifukwa cha celluluse HPMC yokhala ndi ma visa osiyanasiyana ayenera kusankhidwa m'malo osiyanasiyana, komanso momwe chidwi cholondola chitha kuthandiza kukweza ma hpmc.
Makulidwe a ma viru ndi muyeso wamadzimadzi kuti uziyenda ndipo ndi chinthu chofunikira kwambiri mukamasankha zinthu zomwe zimafuna kuti mawonekedwe apadera. Makulidwe amakhudza magwiridwe antchito a HPMC chifukwa imasankha kuthekera kwake kupanga ma gels, kukhudza PH ya yankho, makulidwe ena okutira, ndi zinthu zina zakuthupi. HPMC imapezeka m'makampani osiyanasiyana, mitundu yodziwika kwambiri imakhala ma visction otsika (LV), ma visclence (MV) ndi mamasukidwe apamwamba (HV). Iliyonse yamitundu iyi ili ndi cholinga chapadera ndipo ndi yoyenera kwa malo ena.
Ma visction otsika (LV) HPMC
Ma visc otsika HPMC ali ndi kulemera kwakanthawi kochepa ndipo amasungunuka mosavuta m'madzi. Ndiwo mtundu wamba wa hpmc ndipo umagwiritsidwa ntchito m'mafakitale osiyanasiyana kuphatikizapo chakudya, zodzoladzola, zomangamanga ndi mankhwala osokoneza bongo. LV HPMC imayenereradi mapulogalamu omwe akufuna kuti athetse mayankho a mafayilo owoneka ngati ma gels owoneka bwino, emulsions ndi utoto. Lv hpmc imatha kugwiritsidwanso ntchito pokweza alumali wazakudya, kuchepetsa syneresis ndikupereka mawonekedwe osalala.
LV HPMC imagwiritsidwanso ntchito popanga makonda omanga kuti zizithandizanso zinthu zomwe zimapangidwa ndi simenti monga mativa, ma batolo ndi tile akumata. Zimathandizira kuchepetsa kutayika kwa madzi mumitundu ya simenti, kumalepheretsa kusokonekera, ndikulimbitsa mgwirizano pakati pa zinthu. LV HPMC imagwiritsidwanso ntchito kuwonjezera mphamvu ndi kulimba kwa pulasitala, a Stucco ndi zida zina zokhudzana.
Ma virussion a ma vist (mv) hpmc
Sipakuda vpmc ali ndi kulemera kwakukulu kuposa lv hpmc ndipo sikusungunuka m'madzi. Nthawi zambiri imagwiritsidwa ntchito pogwiritsa ntchito zofunsira zosintha zambiri monga zokutira, ma varnishs ndi inks. MV HPMC ili bwino ndikusintha koyenda ndi kugwiritsa ntchito kuposa LV HPMC, zomwe zimapangitsa yunifolomu komanso makulidwe am'madzi. MV HPMC imatha kugwiritsidwanso ntchito pa mitundu yoopsa ya phwi, kupereka mankhwala osinthanitsa ogwiritsira ntchito mitundu ya mitundu.
MV HPMC imagwiritsidwanso ntchito kwambiri pazinthu zamankhwala, monga mapiritsi oyendetsedwa bwino, chifukwa amachepetsa kufalikira komanso kumasuka kumasulidwa kwa zosakaniza.
Maonekedwe apamwamba (HV) HPMC
HPMCK HPMC HPMC ili ndi kulemera kwakukulu kwa magiredi onse atatu ndipo ndi osungunuka madzi ochepa. Nthawi zambiri imagwiritsidwa ntchito pakugwiritsa ntchito pofuna kukula ndi kukhazikika kwa malo, monga masungu, mafuta ndi ma gels. HV HPMC imathandizira kukulitsa mawonekedwe ndi mafayilo opanga, kupereka zinthu zosangalatsa kwambiri. Itha kugwiritsidwanso ntchito kukhazikika pamawu olumala, kupewa kukhala ndi alumali. Kuphatikiza apo, HV HPMC imagwiritsidwa ntchito nthawi zambiri pamakampani a pepala kuti musinthe pepala ndi kuwunikira.
Pomaliza
Kuwoneka koyenera kwa HPMC ndikofunikira kuti muthe kukonza magwiridwe ake m'malo osiyanasiyana. LV HPMC imayenereradi mapulogalamu omwe akufuna kuti athetse mayankho a mafayilo a mafayilo, pomwe MV HPMC ndi yoyenera mayankho, ma varnish ndi inks. Pomaliza, HV HPMC ndiyoyenera pakugwiritsa ntchito yomwe ikufuna kukula ndi kukhazikika malo monga zowonera, ma gels ndi sosuces. Kusankha ma visction olondola kungakuthandizeni kukonza magwiridwe antchito a HPMC ndikupangitsa kukhala koyenera kugwiritsa ntchito njira zosiyanasiyana.
