Biyo qabow degdeg ah hydroxypropyl methylcellulose (HPMC) Magaca Ingiriisiga: Hydroxypropyl methyl cellulose (HPMC) Magacyada guud: dhumuc dagdag ah, dhumuc weyn, xasiliye emulsion ah, dhumuc kala firdhisan, dhumuclaha antifreeze, cellulose degdeg ah.
Qaybaha ugu muhiimsan iyo qaab dhismeedka kiimikada: eter-ka cellulose aan-ionic ahayn oo laga sameeyay cellulose polymer-ka dabiiciga ah.
Hordhaca badeecada: Hydroxypropyl methylcellulose (HPMC) waa polymer-ka aan-ionic ahayn, eter cellulose aan-ionic ahayn oo laga sameeyay walxaha polymer-ka dabiiciga ah.Alaabtu waa budo is-midabaysa oo aan ur lahayn, dhadhamin, aan sun ahayn, taas oo lagu milmi karo biyo qabow si loo sameeyo xal hufan oo dhumucdiisuna, isku xidhid, kala firdhiso, emulsifying, filim samaynta, laalista, adsorbing, gelling, iyo dusha sare firfircoon , Haysashada qoyaanka iyo sifooyinka kolloid ilaalinta.
Kiimikada maalinlaha ah ee degdegga ah hydroxypropyl methylcellulose HPMC waxaa badanaa loo isticmaalaa kiimikooyinka dharka, alaabta nadiifinta kiimikada maalinlaha ah, qurxinta iyo qaybaha kale;sida shaambada, maydhista jidhka, nadiifinta wejiga, labeenta, kareemka, jel, toner, daryeelka maqaarka Timaha qaboojiyaha, alaabta habaynta, dawada cadayga, candhuufta, biyaha xumbo, iwm.
Astaamaha badeecada ee darajada maalinlaha ah ee kiimikaad degdeg ah hydroxypropyl methylcellulose HPMC:
1. Qalabka ceeriin ee dabiiciga ah, xanaaq yar, waxqabadka khafiifka ah, badbaadada iyo ilaalinta deegaanka;
2. Biyo milanka iyo hantida dhumucda: waxaa lagu milmi karaa biyo qabow, lagu milmi karaa qaar ka mid ah dareerayaasha organic iyo isku dhafka biyaha iyo dareerayaasha organic;
3. Dhumucda iyo viscosity-kordhinta: kororka yar ee kala-baxa wuxuu sameyn doonaa xal hufan oo hufan, daah-furnaan sare, waxqabadka xasilloon, isbeddelka milanka leh ee viscosity, hoose ee viscosity, weynaanta milanka;si wax ku ool ah u wanaajiso xasilloonida socodka nidaamka;
4. Iska caabinta milixda: HPMC waa polymer-ka aan-ionic-ka ahayn, oo yara deggan xalalka aqueous ee cusbada birta ah ama electrolytes organic;
5. Dhaqdhaqaaqa dusha sare: xalalka aqueous ee alaabtu waxay leedahay hawlo dusha sare ah, waxayna leedahay hawlaha iyo sifooyinka emulsification, kolloid ilaalin iyo xasillooni;xiisadda dusha sare waa: 2% xal aqueous waa 42 ~ 56dyn / cm;
6. xasiloonida PH: viscosity ee xalka aqueous waa mid deggan inta u dhaxaysa PH3.0-11.0;
7. Saamaynta biyaha-haysashada: hantida hydrophilic ee HPMC waxaa lagu dari karaa slurry, koollada iyo alaabta baastada si loo ilaaliyo saamaynta sare ee biyaha;
8. Thermal gelation: Marka dareeraha dareeraha ah lagu kululeeyo heerkul gaar ah, wuxuu noqdaa mid mugdi ah ilaa uu ka sameeyo xaalad qulqulaya (poly), si uu xalku u lumiyo viscosity-kiisa.Laakin ka dib qaboojinta, waxay mar kale u rogi doontaa xalalka asalka ah.Heerkulka uu ku dhaco ifafaale jel wuxuu ku xiran yahay nooca badeecada, xoojinta xalka iyo heerka kuleylka;
9. Sifooyin kale: Guryaha filim-samaynta fiican, iyo sidoo kale tiro balaadhan oo ah caabbinta enzyme, kala-baxa iyo isku-duubnida;
10. Viscosity bilawga wakhtiga kiimikaad maalinlaha ah ee hydroxypropyl methylcellulose ee biyaha tuubada heerkulka caadiga ah waa 3 daqiiqo, iyo wakhtiga bilawga viscosity ee biyaha saafiga ah ayaa noqon doona mid gaabis ah, ilaa 30 daqiiqo, si ay u jirto shaqo ku filan Waqti, fududahay in la xakameeyo viscosity. , fududahay in la codsado.
