Hydroxypropyl methyl cellulose da carboxymethyl cellulose sodium za a iya hade

Ana iya haɗa HPMC da CMC

Methyl cellulose fari ne ko fari kamar fibrous ko granular foda;Mara wari, mara daɗi.Wannan samfurin a cikin kumburin ruwa zuwa cikin bayani mai haske ko ɗan turbid colloidal;Rashin narkewa a cikin cikakken ethanol, chloroform ko diethyl ether.Yana da sauri tarwatse da kumbura a cikin ruwan zafi a 80-90 ℃, kuma cikin sauri narkar da bayan sanyaya.Maganin ruwa mai ruwa yana da kwanciyar hankali a dakin da zafin jiki, kuma zai iya gel a babban zafin jiki, kuma gel zai iya canzawa tare da bayani tare da zafin jiki.

Yana da kyau kwarai wettability, watsawa, mannewa, thickening, emulsification, ruwa riƙewa da kuma fim samuwar, kazalika da man fetur impermeability.Fim ɗin yana da kyakkyawan tauri, sassauci da bayyana gaskiya.Saboda ba shi da ionic, zai iya zama jituwa tare da sauran emulsifiers, amma yana da sauƙi don fitar da gishiri, kuma maganin yana da kwanciyar hankali a cikin kewayon PH2 - 12. Sodium carboxymethyl cellulose Wannan samfurin shine gishiri sodium na cellulose carboxymethyl ether. nasa ne na anionic cellulose ether, fari ne ko madara fari fibrous foda ko barbashi, yawa 0.5-0.7 g / cubic santimita, kusan wari, m, hygroscopic.Sauƙi don watsawa cikin ruwa cikin bayani na gelatinous m, wanda ba zai iya narkewa a cikin ethanol da sauran kaushi na halitta.

Lokacin da pH na maganin ruwa ya kasance 6.5 - 8.5, danko na slurry yana raguwa sosai lokacin da pH ta kasance> 10 ko <5, kuma aikin shine mafi kyau lokacin da pH ya kasance 7. Don kwanciyar hankali na thermal, danko yana tashi da sauri a ƙasa. 20 ℃, canje-canje a hankali a 45 ℃, da colloid denaturation da danko da kaddarorin rage muhimmanci a lokacin da mai tsanani na dogon lokaci sama da 80 ℃.Sauƙi mai narkewa a cikin ruwa, bayani mai gaskiya;Yana da matukar kwanciyar hankali a cikin bayani na alkaline, kuma yana da sauƙin yin amfani da ruwa a cikin yanayin acid.Lokacin da darajar pH ta kasance 2-3, hazo zai faru, kuma hazo kuma zai faru a cikin yanayin gishirin ƙarfe mai yawa.Hydroxypropyl methyl cellulose, kuma aka sani da hydroxypropyl methyl cellulose, cellulose hydroxypropyl methyl ether, shi ne zaɓi na sosai tsarki auduga cellulose a matsayin albarkatun kasa, karkashin alkaline yanayi ta musamman etherification da shiri.

Mai narkewa a cikin ruwa da mafi yawan iyakacin duniya C da kuma daidai gwargwado na ethanol / ruwa, propanol / ruwa, dichloroethane, da dai sauransu, wanda ba zai iya narkewa a cikin diethyl ether, acetone, cikakken ethanol, kumburi a cikin ruwan sanyi a cikin fili ko dan kadan turbidized colloidal bayani.Maganin ruwa mai ruwa yana da aiki na saman, babban nuna gaskiya da aikin barga.HPMC yana da dukiyar gel mai zafi.Bayan dumama, samfurin aqueous bayani yana haifar da hazo gel, sannan ya narke bayan sanyaya.Gel zafin jiki na daban-daban bayani dalla-dalla ne daban-daban.
