Hanti Kiimikaad
1. Muuqashada: budo cad, aan lahayn ur iyo dhadhamin.
2. Granularity: heerka gudbinta ee 100 entries ayaa ka weyn 98.5%;heerka gudbinta ee 80 gelis ayaa ka badan 100%.
3. Heerkulka karbohaysiinta: 280-300 ℃.
4. Cufnaanta dusha sare: 0.25-0.70g/cm3(sida caadiga ah waa 0.5g/cm3Bidix iyo midig), oo leh saamiga 1.26-1.31.
5. Heerkulka midabka midabka: 190-200 ℃.
6. Dusha sare: At 25 ℃, 2% xal aqueous waa 42-56dyn / cm.
7. Solubility: kala diri biyaha iyo qaar ka mid ah dareerayaasha organic, sida saamiga ku habboon ethanol / biyaha, propane khamriga / biyaha, dioxethane, etc.Aqueous xal waxay leeyihiin dhaqdhaqaaqa dusha, daahfurnaanta sare iyo waxqabadka xasilloon.Viscosity hoose, milanka weyn, waxqabadka HPMC wuu kala duwan yahay inta u dhaxaysa tilmaamo kala duwan, iyo kala diri muuqaalka muuqaalka ee HPMC ee biyaha ma saameeyaa qiimaha pH.
8. HPMC waxay hoos u dhigtaa maadada methoxy, korodhka dhibcaha jel, hoos u dhaca biyaha, iyo sidoo kale hoos u dhaca dhaqdhaqaaqa dusha sare.
9. HPMC waxa kale oo uu leeyahay awoodda dhumucdiisuna, dheecaan yar cawl milix, xasilloonida pH, haynta biyaha, membranogenesis aad u fiican, iyo sidoo kale tiro balaadhan oo ah caabbinta enzyme, kala firdhiso iyo adhesion.
10. Dhaqdhaqaaqa dusha sare: Xalka aqueous HPMC waxa uu leeyahay shaqo dusha sare ah, waxaana loo isticmaali karaa sidii wakiilka ilaalinta kolloidal, emulsifier iyo kala firdhiso.
11. Gel kuleyl: Marka xalka aqueous ee HPMC lagu kululeeyo heerkul gaar ah, wuxuu noqdaa mid mugdi ah.Gelku wuxuu sameeyaa roobab, laakiin qaboojinta joogtada ah, waxay ku noqotaa xalalka asalka ah. Oo heerkulka jelka iyo roobabku waxay ku xiran yihiin inta badan nooca, xoojinta, iyo heerka kuleylka.
12. xasilloonida pH: Viscosity of xal aqueous HPMC ayaa ku dhawaad ma saameeyaa acid ama saldhigga, iyo qiimaha pH waa mid deggan inta u dhaxaysa 3.0-11.0. Sidaa darteed, viscosity ee xalku wuxuu xasiliyaa inta lagu jiro habka kaydinta muddada-dheer. .
13. Ilaalinta biyaha: HPMC waa wakiilka ilaalinta biyaha oo tayo sare leh. Alaabta waxaa si weyn loogu isticmaalaa qalabka dhismaha, cuntada, qurxinta, iyo dhinacyo kale oo badan.
14. Membranicity: HPMC waxay samayn kartaa filim khafiif ah oo hufan, adag oo dabacsan oo si fiican uga hortagi kara gelinta saliidda. Codsiga cuntada, hantidan waxaa badanaa loo isticmaalaa si loo ilaaliyo biyaha inta lagu jiro xilliga qaboojinta iyo saliidda la isku qurxiyo.
15. Isku-xidhka: Waxa loo isticmaali karaa sidii koollo ahaan midabada, rinjiga iyo waraaqaha, laakiin sidoo kale rinjiga iyo dhejiska.
