Codsiga Dahaarka Ethylcellulose ee Matrices Hydrophilic

Ethylcellulose (EC) waa polymer caadi ahaan loo isticmaalo warshadaha dawooyinka si loogu dahaadho habaynta daroogada. Waa polymer-ka hydrophobic kaas oo bixin kara caqabad si looga ilaaliyo daawada qoyaanka, iftiinka, iyo arrimaha kale ee deegaanka. Dahaarka EC waxa kale oo ay wax ka beddeli karaan sii daynta dawada qaabaynta, sida iyagoo siinaya muuqaal sii dayn joogto ah.

Matrices Hydrophilic waa nooc ka mid ah samaynta daroogada oo ka kooban polymers-biyo-milmi ama biyo-barar, sida hydroxypropyl methylcellulose (HPMC). Matrisyadan waxa loo isticmaali karaa in lagu bixiyo dawada la xakameeyey, laakiin waxa laga yaabaa in ay u nuglaadaan qaadashada biyaha iyo sii daynta daawada xigta. Si looga gudbo xaddidan, dahaarka EC ayaa lagu dabaqi karaa dusha sare ee matrix hydrophilic si loo sameeyo lakab ilaalin ah.

Codsiga dahaarka EC ee matrices hydrophilic waxay ku siin kartaa faa'iidooyin dhowr ah. Marka hore, dahaarka EC wuxuu u dhaqmi karaa sidii xannibaad qoyaan si uu uga ilaaliyo matrix hydrophilic ka qaadashada biyaha iyo sii deynta daawada xigta. Marka labaad, dahaarka EC wuxuu wax ka beddeli karaa sii-deynta daawada ee matrix hydrophilic, sida iyadoo la siinayo muuqaal sii deyn ah oo joogto ah. Ugu dambeyntii, dahaarka EC wuxuu hagaajin karaa xasiloonida jireed ee qaabeynta, sida ka hortagga agglomeration ama ku dhejinta qaybaha.

Codsiga dahaarka EC ee matrices hydrophilic waxaa lagu gaari karaa iyadoo la isticmaalayo farsamooyin daahan oo kala duwan, sida daahan buufin, daahan sariirta dareere, ama daahan digsiga. Doorashada farsamada dahaarka waxay ku xiran tahay arrimo ay ka mid yihiin sifooyinka qaabeynta, dhumucda daahan ee la doonayo, iyo miisaanka wax soo saarka.

Marka la soo koobo, codsiga dahaarka EC ee matrices hydrophilic waa istaraatijiyad caadi ah oo ka jirta warshadaha dawooyinka si wax looga beddelo astaanta siideynta oo loo wanaajiyo xasilloonida qaababka daroogada.
