Saabuunta Thickener Hydroxypropyl Methyl Cellulose Ether HPMC
Viscosity sare HPMC hydroxypropyl methyl cellulose Dhumucda Loogu talagalay budada putty:
1) Muuqashada: HPMC waa nonionic cellulose ether, budada cawl-cad cad ama granule, aan ur iyo dhadhan lahayn, milmi biyo qabow, glacial acetic acid, ethanol, methanol iyo propylene glycol, wax yar ku milmay acetone ku xiran tahay heerka beddelka, ficil ahaan aan lagu milmi karin biyaha kulul, ethylene glycol iyo toluene. HPMC waxa lagu milmay isku dar ah 10% methanol iyo 90% methylene chloride si loo sameeyo xalal kolloidal ah.
2) Xalka HPMC wuxuu leeyahay dhaqdhaqaaq dusha sare ah, daahfurnaan sare, iyo waxqabad xasilloon. Marka lagu kululeeyo heerkul gaar ah, xalku wuxuu noqdaa daruur ama wuxuu sameeyaa jel qulqulaya. Si kastaba ha noqotee, xalku wuxuu noqdaa mid cad mar kale qaboojinta ka dib. Noocyada kala duwan ee HPMC waxay leeyihiin heerkul-kulul oo kala duwan. Solubilityku wuu ku kala duwan yahay viscosity. Maqnaanshaha hoose, milanka sare ee uu leeyahay. Noocyada kala duwan ee HPMC way ku kala duwan yihiin guryaha qaarkood oo milmayntooda biyaha ma saamayso pH.
3) Cabbirrada walxaha: 100% heerka gudbinta 80 mesh.
4) Cufnaanta muuqata: 0.25-0.70 g/mL (badanaa qiyaastii 0.5 g/ml), cufnaanta gaarka ah 1.26-1.31mL.
5) heerkulka isbeddelka midabka: 190-200 ° C; Heerkulka kaarboonaynta:280-300°C.
6) Xiisadda dusha sare:42-56 dyn/cm (2% xal aqueous).
7) Maadada methoxy ee sare ee HPMC, heerkulka gelation hoose, iyo milanka sare ee biyaha iyo dhaqdhaqaaqa dusha sare.
8) HPMC waxay leedahay sifooyin kale, tusaale ahaan, hantida dhumucdeeda, xasiloonida pH, haynta biyaha, haynta filim samaynta heer sare ah, kala firdhisanaan wanaagsan iyo awooda xabaasha.

Alaabooyinka Youngcel waxaa ka mid ah dhammaan noocyada alaabooyinka dareeraha ah sida nadiifiyeyaasha sagxadda, saabuunta iyo alaabta saxanka lagu dhaqo oo leh pH inta u dhaxaysa 6- 8
DhalinyaroTanil waxaa loo isticmaali karaa dhumuc ahaan si loo hagaajiyo rheology ee saabuunta dareeraha ah, la qabsiga muuqaalka la rabo iyo joogteynta habboon.
DhalinyaroTanil waxay awood u siinaysaa qaacidooyinka viscous iyo nadiifiyeyaasha jel inay noqdaan kuwo faa'iido leh oo aad u wanaagsan, sababtoo ah DhalinyaroTanil waxay u ogolaan doontaa nadiifiyeyaasha jel inay ku baxaan dusha sare oo ay shaqeeyaan wakhti dheer, sidaas darteed natiijo nadiif ah oo wanaagsan.
