HPMC (hydroxypropyl methylcellulose) ndi zinthu zamankhwala zomwe zimagwira ntchito yofunika m'mafakitale ambiri. Ndiwosakhazikika, mopindika pang'ono ndi zinthu zosiyanasiyana zogwirizira, kuphatikizapo kukula, kuphatikiza, kupanga mafilimu, kugwiritsidwa ntchito kwambiri, ndi mankhwala, mankhwala a tsiku lililonse.
(1) Makhalidwe a HPMC
Musanakambirane ntchito zake za mafakitale, ndikofunikira kumvetsetsa mawonekedwe ofunikira a HPMC. Otsatirawa ndi ena ofunikira a HPMC:
Kukula: HPMC imatha kuwonjezera mamasukidwe a makina amadzimadzi, makamaka pamakina okhazikika m'madzi. Izi zimapangitsa kuti zikhale zothandiza monga wothandizila kukula mu ntchito zosiyanasiyana, makamaka pomanga zomanga.
Katundu wopanga makanema: hpmc ali ndi luso lopanga mafilimu ndipo amatha kupanga ma yunifolomu komanso mafilimu owonekera. Nthawi zambiri imagwiritsidwa ntchito m'mafakitale ofunda komanso opangira mankhwala.
Kusunga kwamadzi: HPMC imatha kuchepetsa kuchepa kwa madzi ndikuchedwetsa madzi. Nthawi zambiri imagwiritsidwa ntchito kusunga chinyontho chomanga ndi chakudya.
Mafuta am'madzi: hpmc amapanga gel osakaniza pang'onopang'ono ndipo amagwiritsidwa ntchito kwambiri mu chakudya ndi mafakitale opangira mankhwala.
Kukhazikika: HPMC imalimbana ndi asidi ndi alkalis ndipo amakhalabe khola mkati mwa ph, motero imatha kusintha mafakitale osiyanasiyana.
(2) Kugwiritsa ntchito HPMC mu minda yosiyanasiyana ya mafakitale
1. Makampani omanga
HPMC imagwiritsidwa ntchito kwambiri m'munda womanga, makamaka matope owuma, putty ufa, zomata za matabwa, khoma lakunja limapereka ndi zida zothira madzi. Ntchito zapaderazo zikuphatikiza:
Matope matope: hpmc imatha kukula, kusunga madzi ndikuwongolera mapangidwe omangira matope. Malo ake osunga madzi amathandizira Smentant Slorry kuti ikhale chinyezi choyenera panthawi yogwiritsa ntchito simenti ya simenti itamalizidwa, potengera kulimba kwa matope. Kuphatikiza apo, HPMC imatha kuwonjezera matope a matope, kuchepetsa matope, ndikusintha mphamvu yomanga.
Tile zomatira: Kubisalira mphamvu ya ma tile kumachititsa kovuta kwa matatchire otetezeka. Mphamvu yolumikizana ndi kugwirizanitsa kwamadzi kwa HPMC imatha kukonza magwiridwe antchito a mataule, onjezerani madzi pomanga, ndikupewa kupachika kokhazikika.
Pukuta ufa ndi khoma la khoma la khoma: Mu khosi lakumanja, kuwonjezera kwa HPMC kumatha kusintha magwiridwe antchito am'madzi, ndikuwonetsetsa kuti zomangamanga.
2. Makampani ogulitsa mankhwala
M'makampani opanga mankhwala, hpmc amagwiritsidwa ntchito pokonzekera mankhwala ophikira, makamaka kukonzekera kolimba ndi kukonza magetsi kukomoka. Mapulogalamu Akuluakulu akuphatikiza:
Kuphimba Mankhwala: HPMC, monga Wothandizira Wopanga mafilimu, kumatha kupanga mankhwala oteteza kuti apange mapiritsi kuti apangitse matelowo kuti azitha kumeza ndikuteteza mankhwalawa pachilengedwe. Kuphatikiza apo, imatha kuyang'anira kumasulidwa kwa mankhwala osokoneza bongo ndikulanda moyo wake.
Mapulogalamu omasulidwa: Kapangidwe ka HPMC kuloleza kuti ikhale yofunika kwambiri pakutulutsa kokhazikika. Ndi kutupa ndikupanga gel m'matumbo, imatha kuwongolera kuchuluka kwa mankhwalawa ndikupewa zovuta zomwe zimachitika chifukwa cha mankhwalawa mwachangu.
3. Makonda
HPMC imagwiritsidwa ntchito ngati thickener, emulsifier ndi okhazikika m'makampani azakudya. Chitetezo chake chadziwika kwambiri ndi mabungwe otetezeka a chakudya padziko lonse lapansi. Ntchito zapaderazo zikuphatikiza:
Zowonjezera zowonjezera
Zakudya zotsika kwambiri: hpmc ndi fiber yotsika kwambiri yomwe imatha kusintha zinthu zamafuta mu chakudya, zomwe zimatipatsa satifiketi komanso kufota kwa zakudya zotsika ndi zinthu zochepetsetsa.
4. Zovala ndi zojambula
HPMC imagwiritsidwa ntchito kwambiri pa utoto ndi utoto wopaka utoto ngati thiccener, okhazikika ndi othandizira makanema. Ubwino wapadera womwe umaphatikizapo:
Katundu wopanga mafilimu: hpmc amatha kupanga filimu yokhazikika kuti ipititse patsogolo madzi ndi abrasion abrasion kutsutsana.
Sinthani kufanana kwa zokutira: Kuchulukitsa kwa HPMC kumathandizira kuti ithetse bwino za zokutira mu zokutira, pewani kusakazidwa, ndikuwongolera zokutira.
5.
Mwa mankhwala amchere tsiku ndi tsiku, HPMC nthawi zambiri amagwiritsidwa ntchito mu mano, shampoo, zinthu zosamalira khungu ndi zinthu zina ngati ThundKener, Wooyir-Wopanga makanema. Udindo wake mu zodzola zake sikuti ndikungowonjezera chisangalalo cha malonda, komanso kupereka filimu yoteteza ku khungu kuti isawononge chinyezi.
(3) Momwe mungagwiritsire ntchito bwino HPMC pa mafakitale
Ngakhale HPMC ndi yamphamvu komanso yogwiritsidwa ntchito kwambiri, kuti igwiritse ntchito bwino HPMC mu mafakitale osiyanasiyana, muyenera kuyambira pazinthu zotsatirazi:
Sankhani kufotokozera koyenera kwa HPMC
HPMC ili ndi mafotokozedwe osiyanasiyana malinga ndi kuchuluka kwa miyeso ndi kunenepa kwambiri. HPMC ya zojambula zosiyanasiyana zimakhala ndi mitundu yosiyanasiyana monga kususuka, mafakisoni, ndi kutentha kwa gel. Pazolinga zingapo, zogwirizana zoyenera ziyenera kusankhidwa malinga ndi zomwe mukufuna. Mwachitsanzo, zokutira ndi zofuna za ma vincy, hpmc yokhala ndi kulemera kwakukulu komanso mafayilo apamwamba ayenera kusankhidwa; Ali mu zokutira za mankhwala, mitundu ya HPMC yokhala ndi kutentha kotsika kumafunikira kusankhidwa.
Kuwongolera ndalama zomwe zimawonjezeredwa
Kuchuluka kwa hpmc kumakhudza mwachindunji magwiridwe antchito. Kuchuluka kwa hpmc yoyenera kusintha magwiridwe antchito, koma kuchuluka kwambiri kumatha kuyambitsa mamasukidwe kwambiri ndikukhudze ntchito zomanga. Kutengera ndi gawo lofunsira, kuchuluka kwa HPMC yowonjezeredwa ili pakati pa 0,1% ndi 2%. Zowonjezera zoyenera ziyenera kutsimikiziridwa poyeserera kuti mukwaniritse zomwe mukufuna.
Njira Yokhutiritsa Yoyenerera
Kufalikira kwa HPMC m'madzi kumakhudzidwa ndi kutentha, kumeta ubweya ndi nthawi yosangalatsa. Pofuna kusungunula hpmc, nthawi zambiri kumalimbikitsidwa kutilepheretsa madzi ozizira choyamba, kenako pang'onopang'ono kuziteteza mpaka kutentha koyenera kuti usungunuke kwathunthu. Pewani kuwonjezera HPMC mwachindunji pamatenthedwe kwambiri kuti mupewe mapangidwe a gel okhazikika.
Synergy yokhala ndi zina zowonjezera
HPMC imagwiritsidwa ntchito limodzi ndi zina zowonjezera monga ma pulasitiki komanso othandizira olumikizirana kuti apititse patsogolo momwe zinthu ziliri. Mwa zina zomangira, hpmc pamodzi ndi mowa wa polyvinyl, starch ether, etc. amatha kukonza kusinthasintha ndi kupindika kwa matope.
HPMC yakhala ikugwiritsidwa ntchito kwambiri pomanga, mankhwala, chakudya, zokutira ndi mafakitale ena chifukwa cha mawonekedwe ake apadera ndi mankhwala. Pogwiritsa ntchito ntchito, posankha zofunikira, kuwongolera kuchuluka kwake, kusungunuka momveka bwino, ndikugwiritsa ntchito molumikizana ndi zowonjezera za HPMC kungakhale bwino komanso kukonza mtengo ndi magwiridwe antchito.
