Saabuunta Thickener Hydroxypropyl Methyl Cellulose Ether HPMC
Viscosity sareHPMChydroxypropyl methyl celluloseDhumucdaLoogu talagalay budada putty:
1) Muuqashada:HPMCwaa ether cellulose nonionic, budo cad-cawlan ama granule, aan ur lahayn oo aan dhadhan lahayn, ku milmay biyo qabow, glacial acetic acid, ethanol, methanol iyo propylene glycol, wax yar ku milma acetone iyadoo ku xiran heerka beddelka, ficil ahaan aan milmin 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 daruuro 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.Solubility waa ku kala duwan yahay viscosity.Hooska viscosity, ayaa ah mid aad u sarreeya oo ay leedahay.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 karbonaynta: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, hantida samaynta filim heer sare ah, kala firdhisanaan wanaagsan iyo awooda xabaasha.

Alaabooyinka Youngcel waxa ka mid ah dhammaan noocyada alaabta dareeraha ah sida kuwa nadiifiya sagxada, saabuunta iyo alaabta saxanka lagu dhaqo oo leh pH inta u dhaxaysa6- 8
Dhalinyarocelwaxaa loo isticmaali karaa dhumuc ahaan si loo hagaajiyo rheology ee saabuunta dareeraha ah, la qabsiga muuqaalka la rabo iyo joogteynta habboon.
Dhalinyarocel Waxay awood u siinaysaa caanaha viscous iyo nadiifiyeyaasha jel inay noqdaan kuwo faa'iido leh oo aad u wanaagsan, sababtoo ahDhalinyarocelwaxay u ogolaan doontaa nadiifiyeyaasha jel inay ku baxaan dusha oo ay shaqeeyaan wakhti dheer, sidaas darteed natiija nadiifin ah oo wanaagsan.
