Nezvedambudziko rekupisa kwegelHydroxypropyl Methyl Cellulose HPMC, vashandisi vazhinji havanyanyi kutarisisa dambudziko rekupisa kwegel kweHydroxypropyl Methyl Cellulose. Mazuva ano, Hydroxypropyl Methyl Cellulose inowanzosiyaniswa zvichienderana nekusimba kwayo, asi kune dzimwe nzvimbo dzakasarudzika nemaindasitiri akasarudzika, hazvina kukwana kungoratidza kusimba kwechigadzirwa chete. Zvinotevera zvinotsanangura muchidimbu kupisa kwegel kweHydroxypropyl Methyl Cellulose.
Huwandu hweboka reMethoxyl hunoenderana zvakananga nehuwandu hwekusvira kwe cellulose, uye huwandu hweboka reMethoxyl hunogona kugadziriswa nekudzora fomura, tembiricha ye reaction uye nguva ye reaction. Panguva imwe chete, huwandu hwekusashanda hunokanganisa huwandu hwekutsiva Hydroxyethyl kana Hydroxypropyl. Saka, kuchengetwa kwemvura kwe cellulose ether nekupisa kwakanyanya kwegel kuchava kwakashata. Maitiro aya ekugadzira anofanirwa kuongororwa, saka hazvisi zvekuti mutengo wekugadzira cellulose ether wakaderera kana huwandu hweMethoxy hwakaderera, zvakasiyana, mutengo uchave wakakwira.
Tembiricha yegel inoonekwa nemapoka emethoxyl, uye kuchengetwa kwemvura kunoonekwa nemapoka eHydroxypropoxy. Kune mapoka matatu chete anotsiva cellulose. Tsvaga tembiricha yako yakakodzera yekushandisa, kuchengetwa kwemvura kwakakodzera, wobva waona muenzaniso we cellulose iyi.
Kupisa kwegel chinhu chakakosha pakushandisaether ye celluloseKana tembiricha yemhepo yadarika tembiricha yegel, cellulose ether ichaparadzaniswa nemvura uye icharasikirwa nekuchengetedza kwayo mvura. Tembiricha yegel yecellulose ether iri pamusika inogona kusangana nezvinodiwa nenzvimbo yekushandisa mortar (kunze kwenzvimbo dzakasarudzika). Ini pachangu ndinofunga kuti hazvidikanwi kunyatsotarisa performance index ye gel tembiricha pakushandisa mortar. Ehe, kugadzirwa kwe cellulose ether Vagadziri vanofanira kufunga nezvazvo.
