1. Hydroxypropyl methylcellulose (HPMC)ndi non-ionic cellulose ether opangidwa kuchokera ku ulusi wa thonje wachilengedwe kapena zamkati zamatabwa kudzera munjira zingapo zopangira mankhwala monga alkalization, etherification, ndi kuyenga. Malinga ndi mamasukidwe akayendedwe ake, HPMC akhoza kugawidwa mu kukhuthala mkulu, sing'anga mamasukidwe akayendedwe, ndi otsika mamasukidwe akayendedwe mankhwala. Pakati pawo, otsika mamasukidwe akayendedwe HPMC chimagwiritsidwa ntchito m'madera ambiri chifukwa cha madzi solubility kwambiri, filimu kupanga katundu, lubricity, ndi kubalalitsidwa bata.
2. Basic makhalidwe otsika mamasukidwe akayendedwe HPMC
Kusungunuka kwamadzi: Low mamasukidwe akayendedwe HPMC mosavuta sungunuka m'madzi ozizira ndipo akhoza kupanga mandala kapena translucent viscous njira, koma insoluble m'madzi otentha ndi zosungunulira zambiri organic.
Low mamasukidwe akayendedwe: Poyerekeza ndi sing'anga ndi mkulu mamasukidwe akayendedwe HPMC, yankho ake ali kukhuthala otsika, kawirikawiri 5-100mPa · s (2% amadzimadzi njira, 25 ° C).
Kukhazikika: Imakhala ndi kukhazikika kwamankhwala abwino, imalekerera ma acid ndi alkalis, ndipo imatha kukhala yokhazikika mumitundu yambiri ya pH.
Katundu wopanga mafilimu: Itha kupanga filimu yofananira pamwamba pa magawo osiyanasiyana, okhala ndi zotchinga zabwino komanso zomata.
Lubricity: Itha kugwiritsidwa ntchito ngati mafuta kuti muchepetse kukangana ndikuwongolera magwiridwe antchito azinthu.
Zochita zapamtunda: Zili ndi luso la emulsification ndikubalalitsa ndipo zitha kugwiritsidwa ntchito pamakina oyimitsa kuyimitsidwa.
3. Ntchito minda ya otsika mamasukidwe akayendedwe HPMC
Zomangira
Tondo ndi putty: Mumatope owuma, matope odziyika okha, ndi matope opaka pulasitala, HPMC yotsika kwambiri imatha kupititsa patsogolo ntchito yomanga, kupititsa patsogolo kusungunuka kwamadzi ndi mafuta, kupititsa patsogolo kusungidwa kwamadzi mumatope, ndikuletsa kusweka ndi kuphulika.
Zomatira matailosi: Zimagwiritsidwa ntchito ngati zokhuthala komanso zomangira kuti zithandizire kukonza zomangamanga komanso mphamvu zomangirira.
Zopaka ndi utoto: Monga chowonjezera komanso choyimitsa, zimapanga yunifolomu ya zokutira, zimateteza kusungunuka kwa pigment, komanso kumapangitsanso kutsuka ndi kusanja katundu.
Mankhwala ndi chakudya
Zothandizira Zamankhwala: Low-viscosity HPMC ingagwiritsidwe ntchito mu zokutira mapiritsi, zotulutsa zokhazikika, zoyimitsidwa, ndi zodzaza makapisozi m'makampani opanga mankhwala kuti akhazikike, asungunuke, ndi kutulutsa pang'onopang'ono.
Zowonjezera zakudya: zimagwiritsidwa ntchito ngati zonenepa, zopangira ma emulsifiers, zolimbitsa thupi pokonza chakudya, monga kukonza kakomedwe ndi kapangidwe kazinthu zophikidwa, mkaka ndi timadziti.
Zodzoladzola ndi zinthu zosamalira munthu
Muzinthu zosamalira khungu, zoyeretsa nkhope, zowongolera, ma gels ndi zinthu zina, HPMC ingagwiritsidwe ntchito ngati thickener ndi moisturizer kupititsa patsogolo kapangidwe ka mankhwala, kuti ikhale yosavuta kugwiritsa ntchito ndikuwonjezera chitonthozo cha khungu.
Ceramics ndi kupanga mapepala
M'makampani a ceramic, HPMC itha kugwiritsidwa ntchito ngati mafuta opangira mafuta komanso kuumba kuti apititse patsogolo kusungunuka kwamatope ndikuwongolera mphamvu zathupi.
M'makampani opanga mapepala, amatha kugwiritsidwa ntchito popaka mapepala kuti azitha kusalala komanso kusinthasintha kwa pepala.
Agriculture ndi kuteteza chilengedwe
Low mamasukidwe akayendedwe HPMC angagwiritsidwe ntchito suspensions mankhwala kuti mankhwala bata ndi kuonjezera nthawi kumasulidwa.
Mu zipangizo zachilengedwe, monga zowonjezera madzi mankhwala, fumbi suppressants, etc., akhoza kumapangitsanso kubalalikana bata ndi kusintha ntchito zotsatira.
4. Kugwiritsa ntchito ndi kusunga otsika mamasukidwe akayendedwe HPMC
Njira yogwiritsira ntchito
Low mamasukidwe akayendedwe HPMC kawirikawiri amapereka ufa kapena granular mawonekedwe ndipo akhoza mwachindunji omwazikana m'madzi ntchito.
Pofuna kupewa agglomeration, tikulimbikitsidwa kuwonjezera pang'onopang'ono HPMC kumadzi ozizira, kusonkhezera mofanana ndiyeno kutentha kuti kusungunuke kuti mupeze zotsatira zabwino zowonongeka.
Mu ufa wowuma, ukhoza kusakanikirana mofanana ndi zinthu zina za ufa ndikuwonjezeredwa kumadzi kuti zisungunuke bwino.
Zofunikira posungira
HPMC iyenera kusungidwa pamalo owuma, ozizira, abwino mpweya wabwino kupewa kutentha ndi chinyezi.
Khalani kutali ndi ma okosijeni amphamvu kuti mupewe kusintha kwamankhwala kuti zisasinthe magwiridwe antchito.
Kutentha kosungirako kumalimbikitsidwa kuyendetsedwa pa 0-30 ℃ ndikupewa kuwala kwa dzuwa kuti zitsimikizire kukhazikika ndi moyo wautumiki wa chinthucho.
Low viscosity hydroxypropyl methylcelluloseimagwira ntchito yofunika kwambiri m'mafakitale ambiri monga zomangira, mankhwala ndi zakudya, zodzoladzola, kupanga mapepala a ceramic, ndi kuteteza zachilengedwe zaulimi chifukwa cha kusungunuka kwake kwamadzi, kutsekemera, kusunga madzi komanso kupanga mafilimu. Makhalidwe ake otsika amawonekedwe a viscosity amapangitsa kuti ikhale yoyenera pazochitika zogwiritsira ntchito zomwe zimafuna fluidity, dispersibility ndi bata. Ndi chitukuko chosalekeza chaukadaulo wamafakitale, gawo logwiritsira ntchito la low viscosity HPMC lidzakulitsidwanso, ndipo liwonetsa chiyembekezo chokulirapo pakuwongolera magwiridwe antchito ndi kukhathamiritsa njira zopangira.
