Hpmc hydroxypypyl mealose cellulose wopanga fakitale wogulitsa wogulitsa
Kodi kugwiritsa ntchito HPMC yayikulu ndi kotani?
HPMC ikhoza kugawidwa mu: Grace Womanga, kalasi ya chakudya ndi kalasi ya zamankhwala pogwiritsa ntchito.
HPMC imagwiritsidwa ntchito kwambiri m'magawo omanga, zokutira, matekenti, matenti, mankhwala, chakudya, nsalu, zodzikongoletsera, fodya komanso mafakitale ena.
Pakadali pano, ambiri mwa omanga nyumba, mu kalasi yomanga, matope a ufa ndi akulu, pafupifupi 90% amagwiritsidwa ntchito popanga ufa, ena onse amagwiritsidwa ntchito popanga matope a simenti ndi gulu.
Kodi zida zazikulu za HPMC ndi ziti?
HPMC ikuluikulu ya vpmc: Woyengeka thonje, chloromethane, propylene oxide. Zida zina zaiwisi ndi, piritsi alkali, asidi, tulparopanol ndi zina zotero.
- HPMC imagawidwa mitundu ingapo, kusiyana kogwiritsa ntchito bwanji?
HPMC imatha kugawidwa kuti ikhale yopumira komanso kutentha.
Zogulitsa nthawi yomweyo, m'madzi ozizira amabalalika m'madzi, nthawi ino madzi alibe mamasukidwe, chifukwa HPMC imangomwa madzi, palibe kufalikira kwenikweni. Pafupifupi mphindi ziwiri, mawike amadzimadzi amawonjezeka pang'onopang'ono, ndikupanga mafilimu owonekera. Ntchito zosiyanasiyana, mu ufa ndi matope, ndi guluu wamadzimalo ndi utoto, zitha kugwiritsidwa ntchito, palibe taboo.
Zinthu zotentha zotentha, m'madzi ozizira, zimatha kusungidwa mwachangu m'madzi otentha, pomwe kutentha kumatsika mpaka kutentha, mpaka mapangidwe a colous owoneka bwino. Itha kugwiritsidwa ntchito ngati ufa ndi matope, m'matomitala akumwa ndi utoto, padzakhala gulu la gulu, sizingagwiritsidwe ntchito.
Kodi ndi zisonyezo zazikulu zaukadaulo za hpmc ndi ziti?
Hydroxypyl ndi mafakisoni, ogwiritsa ntchito ambiri amakhudzidwa ndi mndandanda wazinthu ziwirizi.
Ma hydroxypropyl omwe ali pamwamba, kusungidwa kwamadzi nthawi zambiri kumakhala bwino.
Mafayilo, kusungidwa kwamadzi, wachibale (koma osati mtheradi) alinso wabwinoko, komanso mafayilo, mu matope, mu matope a Smenti, amagwiritsa ntchito bwino ena.
Kodi ndi ma vinyadi angati omwe ali oyenera hpmc?
Udindo wofunikira kwambiri wa hpmc ndi kusungidwa kwamadzi, kenako ndikukula.
Pukuta la putty nthawi zambiri limakhala. Malingana ngati kusungidwa kwamadzi ndikwabwino, mafakisoniwo ali otsika (70,000-80000), kutanthauza kuti kusungidwa kwamadzi ndikwabwino, pamene zikuwoneka bwino pamadzi osungira.
Kufunikira kwa matope ndi kutalika kwina, ndikufuna pafupifupi 150,000 kuti ndikhale bwino kugwiritsa ntchito.
Ntchito Zoyenera: Muyenera kugulitsa zinthu mwachangu, mamasukidwe apamwamba.
