Hydroxypropyl methylcellulose (hpmc) ethel eyal yomwe imagwiritsidwa ntchito m'mafakitale osiyanasiyana, kuphatikiza gypsum m'makampani omanga. Pagawo la magawo ambiri izi limathandizanso kukonza magwiridwe antchito ndi katundu wa pulasitala wa gypsum.
1. Kuyambitsa kwa HPMC:
Hydroxypropyll methylcellulose ndizopanga zopangidwa ndi cellulose yachilengedwe. Amapangidwa ndi kuchiritsa cellulose ndi ma propylene oxide ndi methyl chloride. Zotsatira zake ndi polymer-sungunuka wamadzi wokhala ndi zinthu zapadera zomwe zingapeze mapulogalamu osiyanasiyana.
2. Magwiridwe a HPMC:
Kusungunuka kwamadzi: hpmc kumasungunuka mosavuta m'madzi, ndikupanga njira yowonekera komanso yopanda utoto.
Katundu wopanga makanema: Katundu wopanga makanema amathandizira kupanga filimu yoteteza pamtunda.
Miyendo yamatenthedwe: HPMC imagwirizana ndi mizere yosinthika, yomwe imatanthawuza kuti itha kupanga gel osatentha ndikubwerera ku chizilitso pakuzizira.
Ma Ukuwoneka: Makutu a HPMC Njira ya HPMC ikhoza kusinthidwa malinga ndi kuchuluka kwa zolowa m'malo mwa zotsekemera.
3. Kugwiritsa ntchito HPMC ku gypsum:
Kusunga kwamadzi: HPMC imagwira ntchito ngati mankhwala osungira madzi ku gypsum, kupewa kutaya madzi mwachangu panthawi yokhazikika. Izi zimawonjezera kuyendetsa magetsi ndipo imapereka moyo wogwira ntchito.
Kutsatira mokweza: Katundu wamafilimu a HPMC amathandizira kukonza ma SECCCO yotsatira magawo osiyanasiyana, ndikupanga mgwirizano wamphamvu.
Kuwongolera Kosasinthika: Mwa kuwongolera maulendo a gypsum osakaniza, hpmc imathandizira kusasinthika, kuonetsetsa kuti ma yunifolome amatsirize.
Kukana Kukana: Kugwiritsa ntchito HPMC mu pulasitala kumathandizira kusintha ndikuchepetsa mwayi wokhala ndi ming'alu yomalizidwa.
Kukhazikitsa Nthawi: HPMC kumatha kusintha madongosolo a gypsum kuti ithe kusintha kuti akwaniritse zofunika pa ntchito.
4. Mlingo ndi kusakaniza:
Kuchuluka kwa HPMC yomwe imagwiritsidwa ntchito ku gypsum kumatengera zinthu zosiyanasiyana monga katundu wofunikira, gypsum kapangidwe kake ndi zofunikira kugwiritsa ntchito. Nthawi zambiri, imawonjezedwa ku kusakaniza kowirikirako nthawi yosakanikirana. Njira zosakanikirana ndizofunikira kuti zitsimikizike zopezeka ndi ma yunifolomu komanso kuchita bwino.
5.Kutchi ndi chitetezo:
HPMC imagwirizana ndi zowonjezera zina zowonjezera zomwe zimagwiritsidwa ntchito popanga pulasitala. Kuphatikiza apo, imawerengedwa kuti igwiritsidwe ntchito pomanga zinthu zomangamanga ndikugwirizana ndi mfundo zoyenera.
6. Kumaliza:
Hydroxypylm methylcellulose (hpmc) amatenga gawo lofunikira pakuwongolera magwiridwe antchito a gypsum. Malo ake apadera amathandizira kukonza kugwirira ntchito, kutsatira komanso kuchuluka kwa pulasitala. Wowonjezera kwambiri wogwiritsidwa ntchito kwambiri pantchito zomanga, HPMC imatsalira gawo lofunikira kwambiri pazinthu zapamwamba kwambiri.
