Sharaxaada Alaabta:
Hydroxypropyl Methylcellulose (HPMC) waa budo cad oo aan ur lahayn, aan sun ahayn. Ka dib marka si buuxda loogu milmo biyaha, waxay samayn doontaa xal muuqda oo muuqda. Waa eter cellulose aan-ionic ahayn oo laga sameeyay maaddooyinka polymer-ka dabiiciga ah iyada oo loo marayo taxane kiimiko ah. Waxay leedahay sifooyinka dhumucdiisuna, adhesion, kala firidhsan, emulsification, samaynta filimada, ganaax, adsorption, gelation, dhaqdhaqaaqa dusha, xajinta ee qoyaan iyo ilaalinta colloid.
Codsiga:
Biyo milanka iyo kartida dhumucda: waxay ku milmi kartaa biyo qabow, waxayna samaysaa xal hufan.
Kala dirida dareerayaasha organic: Sababtoo ah waxay ka kooban tahay qadar go'an oo kooxaha methoxy hydrophobic, alaabtan waxaa lagu milmi karaa qaar ka mid ah dareerayaasha organic.
Degganaanshaha qiimaha PH: Viscosity ee xalka aqueous ee HPMC waa mid xasiloon inta u dhaxaysa qiimaha PH 3.0-11.0.
Dhaqdhaqaaqa dusha sare: Xalka aqueous HPMC wuxuu leeyahay hawlo korka ah. Waxay leedahay saamayn emulsifying, ilaalinta awoodda kolloid iyo xasilloonida qaraabo.
Gelation-ka kulaylka: Marka kulaylka ka sarreeya heerkul gaar ah, xalka aqueous ee HPMC wuxuu noqon karaa mugdi, dhalin kara roobab, oo lumin kara viscosity. Si kastaba ha ahaatee, waxay si tartiib tartiib ah isu beddeshay xalalka asalka ah ka dib qaboojinta.
Maaddooyinka dambaska hooseeya: HPMC waa non-ionic, waxaa lagu dhaqi karaa biyo kulul inta lagu jiro habka diyaarinta oo si wax ku ool ah loo sifeeyo, sidaas darteed waxa ku jira dambaska aad ayuu u hooseeyaa.
Iska caabbinta milixda: Maadaama badeecadani ay tahay elektrolyte aan ahayn ionic iyo non-polymeric, waxay ku xasilloon tahay xalalka biyaha ee cusbada birta ah ama elektrolytka organic.
Saamaynta haynta biyaha: Sababtoo ah HPMC waa hydrophilic iyo xalkeeda aqueous waa mid aad u muuqda. Waxaa lagu dari karaa hoobiye, gypsum, rinjiga, iwm si loo ilaaliyo biyaha sare ee alaabta.
Caabiyaysa caariyaysi: Waxay leedahay caariyaysi aad u wanaagsan, waxayna leedahay xasillooni viscosity wanaagsan inta lagu jiro kaydinta muddada-dheer.
Saliid: Ku darista HPMC waxay yarayn kartaa isku xidhka isku xidhka waxayna wanaajin kartaa saliidda alaabta dhoobada ah ee la soo saaray iyo alaabta sibidhka.
Hanti-samaynta filimka: Waxay soo saari kartaa jajabyo xooggan, dabacsanaan, dabacsanaan leh oo leh saliid wanaagsan iyo caabbinta ester.
Qalabka dhismaha, HPMC cellulose waxaa loo isticmaali karaa sidii wakiilka biyaha-haysta iyo dib-u-dejiyaha sibidhka sibidhka looga dhigo mid la soo saari karo.
Xabag ahaan, isticmaalka HPMC ee balastarrada, gypsum-ka, budada dhejiska ah ama qalabka kale ee dhismaha waxay wanaajin kartaa faafintooda waxayna dheerayn kartaa waqtigooda la shaqayn karo.
Haysashada biyaha waxay ka hortagi kartaa koollada inay si dhakhso ah u dillaacdo daahan ka dib, waxayna sidoo kale kor u qaadi kartaa xoogga dahaarka ka dib marka la adkeeyo.
Ka sokow, kiimikooyinka HPMC sidoo kale waxaa loo isticmaali karaa sidii kor-u-qaade xabag ah oo loogu talagalay foornada, marmar, iyo qurxinta caagga ah ee warshadaha dhismaha.
Intaa waxaa dheer, budada HPMC waxaa loo isticmaalaa sidii dhumuc, xasiliye, emulsifier, excipient, iyo wakiilka haynta biyaha ee wax soo saarka warshadaha kale, sida batroolka, dahaarka, qalabka dhismaha, saarayaasha rinjiga, kiimikooyinka beeraha, khad, daabacaadda dharka iyo dheehidda. ceramics, warqad-samaynta, waxyaalaha la isku qurxiyo, iwm.
Xidhmada: 25 kgs/bac ama sida aad codsato.
Kaydinta: Ku kaydi meel hawo leh oo qallalan.
Heerarka la fuliyay: Heerka caalamiga ah.
