Hydroxypropymethylcellulose (hpmc) ndi polder opanga madzi opangidwa ndi madzi ochokera ku cellulose. Amagwiritsidwa ntchito kwambiri pamafakitale osiyanasiyana chifukwa cha kukula kwake, kumanga ndi kutulutsa zinthu. Chimodzi mwazinthu zofunika kwambiri za HPMC ndi ngati wothandizira wamadzi omwe amakhala m'mitundu yosiyanasiyana monga zomanga, chakudya, zodzoladzola komanso mankhwala opangira mankhwala.
Kusungidwa kwamadzi ndi chinthu chofunikira kwambiri kwa zinthu zambiri ndi ntchito zambiri. Amanenanso za kuthekera kwa chinthu kuti madzi athetse madzi mkati mwake. M'makampani omanga, kusungidwa kwamadzi ndi mbali yofunika kwambiri pamene kumathandizanso kukhalabe ndi sipi la simenti pochiritsa. Kusintha kwa chinyezi mopitirira muyeso pakuchirikiza muyeso kumatha kubweretsa mgwirizano wosauka komanso kusokonekera kwa simenti, kunyalanyaza kukhulupirika kwa nyumbayo. M'makampani azakudya, kusungidwa kwamadzi ndikofunikira kuti pakhale kapangidwe kazinthu, kukhazikika komanso moyo wa alumali. Mu zodzoladzola, kusunga madzi kumapereka mankhwala komanso kunyowa katundu pakhungu. M'mankhwala opanga mankhwala, kusungidwa kwamadzi ndikofunikira kuti musungunuke ndi luso.
HPMC ndichithandizo chabwino chamadzi chifukwa cha ntchito yake yapadera. Ndi polymer yopanda tanthauzo, yomwe imatanthawuza kuti ilibe ndalama ndipo sizigwirizana ndi mayoke. Ndi hydrophilic, zomwe zikutanthauza kuti ili ndi kuyanja kwamadzi ndikuyitenga mosavuta ndikusungabe mkati mwake. Kuphatikiza apo, HPMC imakhala ndi kulemera kwambiri, komwe kumapangitsa kuti ikhale yothandiza komanso yokongola. Izi zimapangitsa kuti HPMC ikhale yopanda madzi munthawi zosiyanasiyana.
M'makampani omanga, hpmc imagwiritsidwa ntchito ngati wothandizira madzi mu simenti komanso konkriti. Pochiritsa, hpmc imatha kusunga chinyontho mkati mwa simenti, mwakutero kuchepetsa kupukuta ndikuwonetsetsa hydration yoyenera tinthu tambiri. Izi zimapangitsa ubale wamphamvu komanso umachepetsa chiopsezo cha kuwonongeka ndi shrinkage. Kuphatikiza apo, HPMC imatha kukonza simenti komanso kusasinthika kwa simenti, kumapangitsa kuti zikhale zosavuta kugwiritsa ntchito, kufalikira ndi kumaliza. HPMC imagwiritsidwanso ntchito matope matope kuti muwonjezere chotsatsa, kuphatikiza ndi kugwirira ntchito matope. Mphamvu zosunga zamadzi za HPMC ndizofunikira pakuchita ndi kulimba kwa nyumba.
M'makampani azakudya, HPMC imagwiritsidwa ntchito ngati thickener, ribiface ndi emulsifier. Nthawi zambiri zimapezeka m'zinthu zamkaka, zinthu zophika, ndi zakumwa. HPMC imatha kusintha kapangidwe ka chakudya komanso kuchepetsa zakudya komanso kupewa kupatukana ndi zosakaniza. Kuphika, HPMC imatha kuwonjezera kuchuluka kwa mkate ndikusintha mkate. Muzinthu zamchere monga yogati ndi ayisikilimu, hpmc imalepheretsa mapangidwe a makhiristo a ice ndikusintha mawa ndi osalala. Katundu wosunga madzi ndiwofunikira kuti azisunga chinyezi komanso mwatsopano pa alumali moyo wawo.
Mu zodzoladzola, hpmc imagwiritsidwa ntchito ngati thickisier ndi emulsifier mu kirimu, mafuta, ndi shampoos. HPMC imathandizira kufalitsa ndi kusasinthasintha, ndipo amapereka zonyowa komanso zopindulitsa. Katundu wosunga madzi wa HPMC ndiwofunikira kwambiri kwa chinyezi komanso kusungidwa kwa khungu ndi tsitsi, zomwe zimatha kupititsa patsogolo zofewa, zotupa komanso tsitsi. HPMC imagwiritsidwanso ntchito ngati filimu yomwe kale mu ma sunscreens, omwe amatha kupereka choletsa chotchinga ndikuletsa kutayika chinyezi ku khungu.
Mu mankhwala opangira mankhwala, hpmc imagwiritsidwa ntchito ngati binder, zokutira ndi kusungidwa ndi mapiritsi ndi makapisozi. HPMC imatha kusintha ufa wosokoneza bongo ndi maluwa, omwe amatha kuwonjezera kulondola ndi kusasinthika. HPMC imathanso kuperekanso cholepheretsa choteteza komanso kupewa kuwonongeka kwa mankhwala ndi kuyanjana ndi zina. Mphamvu yosungitsa madzi ndi yofunikira kwambiri ku bata komanso bioavailability monga zimawonekera moyenera komanso mayamwidwe m'thupi. HPMC imagwiritsidwanso ntchito m'maso ngati Thicner, yomwe imatha kuyamwa nthawi yolumikizana ndi kusintha kwa mankhwalawa.
Pomaliza, hydroxypropyl methylcellulose (hpmc) ndi madzi ofunikira omwe amagwiranso ntchito zosiyanasiyana monga zomanga, chakudya, zodzoladzola ndi mankhwala osokoneza bongo. Zomwe zimapangidwa ndi HPMC, monga zopanda Ionic, zolemera kwambiri moleclar komanso zolemetsa kwambiri, zimapangitsa kuti ikhale yogwira mtima, bander ndi emulsifier. Zosungidwa zamadzi za HPMC ndizofunikira pakugwira ntchito ndi magwiridwe antchito ndi zinthu. Kugwiritsa ntchito HPMC kumatha kusintha mtunduwo, kukhazikika ndi chitetezo cha zinthu ndikuthandizira kuti anthu azikhala otetezeka.
