Hydroxypropyl methylcellulose (HPMC) ndi ether yopanda ionic cellulose yokhala ndi ntchito zingapo komanso ntchito zambiri.
1. Zipangizo zomangira
M'makampani omanga, HPMC imagwiritsidwa ntchito kwambiri pazinthu monga matope a simenti, zida za gypsum, putty powder ndi zomatira matailosi. Ntchito zake zazikulu ndi izi:
Kusungirako madzi: HPMC imatha kusintha kwambiri kasungidwe ka madzi mumatope ndikuletsa madzi kuti asasunthike mwachangu, potero kumapangitsa ntchito yomanga ndikuchiritsa.
Kukhuthala ndi kudzoza: Kutha kuwonjezera kukhuthala ndi kutsekemera kwa matope, kupangitsa kuti nyumbayo ikhale yosavuta komanso kuchepetsa kuvala kwa zida zomangira.
Anti-cracking: Pokonza kusungirako madzi ndi kumamatira kwamatope, HPMC imatha kuteteza matope ndi pulasitala kuti zisaphwanyike panthawi yochiritsa.
2. Zopaka ndi utoto
M'makampani opanga utoto ndi zokutira, HPMC imagwiritsidwa ntchito ngati thickener, emulsifier ndi stabilizer. Ntchito zake zikuphatikizapo:
Kukhuthala: Wonjezerani kukhuthala kwa utoto, tetezani kugwa, komanso sinthani utotowo kuti ukhale wofanana.
Kukhazikika: Kumathandiza kusunga yunifolomu kubalalitsidwa kwa pigment ndi fillers, kupewa kukhazikika ndi delamination.
Anti-sag katundu: Sinthani magwiridwe antchito a utoto ndikupewa kugwa ndi kudontha.
3. Mankhwala ndi Chakudya
M'makampani opanga mankhwala ndi zakudya, HPMC imagwiritsidwa ntchito kwambiri m'mapiritsi, makapisozi ndi zowonjezera zakudya. Ntchito zake ndi izi:
Kupaka piritsi: Monga chotchinga cha piritsi, HPMC imatha kuwongolera kutulutsidwa kwa mankhwala ndikuteteza mankhwalawa ku chinyezi ndi mpweya.
Chigoba cha kapisozi: HPMC ndiye chinthu chachikulu cha makapisozi amasamba, oyenera omwe amadya masamba ndi anthu omwe amadana ndi makapisozi otengedwa ndi nyama.
Thickeners ndi emulsifiers: M'zakudya, HPMC amagwiritsidwa ntchito ngati thickener, emulsifier ndi stabilizer kusintha maonekedwe ndi kukoma kwa chakudya.
4. Zodzoladzola
M'makampani opanga zodzoladzola, HPMC imagwiritsidwa ntchito pazinthu monga mafuta odzola, mafuta opaka, shampoos ndi mankhwala otsukira mano. Ntchito zake zazikulu ndi izi:
Kunenepa: Kumapereka kukhuthala koyenera komanso kusasinthika, kupangitsa kuti zinthu zikhale zosavuta kuziyika ndikuyamwa.
Kupanga filimu: Pangani filimu yotetezera yowonekera kuti muwonjezere mphamvu ya khungu.
Emulsification ndi Kukhazikika: Imathandiza emulsify ndikukhazikitsa zosakaniza zamafuta amadzi kuti zipewe kukhazikika.
5. Ntchito zina
HPMC imagwiritsidwanso ntchito m'malo ena ambiri monga:
Inki yosindikiza: Imagwira ntchito ngati thickener ndi stabilizer kupititsa patsogolo kusindikiza.
Ulimi: Amagwiritsidwa ntchito ngati chomangira kumatirira mbewu ndi mankhwala ophera tizilombo paulimi kuti mbewuyo ikhale yogwira mtima komanso yomeretsa.
Zovala: Zogwiritsidwa ntchito posindikiza nsalu ndi njira zopaka utoto kuti zithandizire kusindikiza komanso kufulumira kwa utoto.
6. Mbali ndi Ubwino
HPMC amagwira ntchito yofunika kwambiri m'mafakitale osiyanasiyana chifukwa chapadera thupi ndi mankhwala katundu. Zina zake zazikulu ndi izi:
Kusungunuka kwamadzi: HPMC imatha kusungunuka m'madzi ozizira kapena otentha kuti ipange njira yowonekera ya colloidal.
Biocompatibility ndi chitetezo: HPMC ndi yopanda poizoni komanso yopanda vuto, ili ndi biocompatibility yabwino, ndipo imagwiritsidwa ntchito kwambiri m'minda yazakudya ndi mankhwala.
Kukhazikika: Kusamva ma acid, alkalis ndi mchere, kumakhala ndi kukhazikika kwabwino kwambiri ndipo kumatha kugwira ntchito m'malo osiyanasiyana.
Hydroxypropyl methylcellulose amagwiritsidwa ntchito kwambiri pomanga, zokutira, mankhwala, zakudya, zodzoladzola ndi mafakitale ena chifukwa cha kusinthasintha kwake komanso ntchito zabwino. Ntchito zake za thickening, kusungirako madzi, emulsification ndi kukhazikika zimapangitsa kuti zikhale zofunikira kwambiri pazinthu zosiyanasiyana, zomwe zimapangitsa kuti zikhale zofunikira kwambiri kuti ziwongolere ntchito zamalonda ndi chidziwitso cha ogwiritsa ntchito.
