Waxqabadka hydroxypropyl methylcellulose HPMC ee hoobiye

Hydroxypropyl methylcellulose waa mid ka mid ah walxaha muhiimka ah ee ether-ka cellulose ee ku jira hoobiyaha qalalan wuxuuna leeyahay hawlo badan oo hoobiye ah. Hawlaha ugu muhiimsan ee hydroxypropyl methylcellulose ee hoobiye sibidhka waa haynta biyaha iyo dhumucdooda. Intaa waxaa dheer, iyada oo ay ugu wacan tahay isdhexgalka nidaamka sibidhka, waxa ay sidoo kale ka ciyaari kartaa dowr ku yeelashada hawada, dib u dhigista dejinta, iyo hagaajinta xoogga cufan. Saamayn

Waxqabadka ugu muhiimsan ee hydroxypropyl methylcellulose ee hoobiye waa haynta biyaha. Sida isku-darka ether-ka cellulose ee hoobiye, hydroxypropyl methylcellulose waxaa loo isticmaali karaa ku dhawaad ​​dhammaan badeecooyinka hoobiye, badiyaa sababtoo ah sifooyinka biyaha. Guud ahaan, haynta biyaha ee hydroxypropyl methylcellulose waxay la xiriirtaa viscosity, heerka beddelka iyo cabbirka walxaha.

Hydroxypropyl methylcellulose waxaa loo isticmaalaa dhumuc ahaan, saameynteeda dhumucduna waxay la xiriirtaa heerka beddelka, cabbirka walxaha, viscosity iyo heerka wax ka beddelka hydroxypropyl methylcellulose. Guud ahaan marka la hadlo, heerka sare ee beddelka iyo viscosity ee ether cellulose, ka yar size qayb ka iyo aad u cad saamaynta dhumucdiisuna.

Hydroxypropyl methylcellulose, soo bandhigida kooxaha methoxy waxay yaraynaysaa tamarta dusha sare ee xalalka aqueous ee ka kooban hydroxypropyl methylcellulose, sidaa darteed hydroxypropyl methylcellulose waxay leedahay saameyn hawo-mareen ah oo ku saabsan hoobiye sibidhka. Soo geli xaddi ku habboon oo xumbo ah hoobiye. Sababtoo ah "saameynta kubbadda" ee goobooyinku,

Waxqabadka dhismaha ee hoobiye ayaa la wanaajiyey, halka soo bandhigida xumbo hawada ay kordhiso dhalidda hoobiye. Dabcan, xadiga hawada la isku shubay ayaa loo baahan yahay in la xakameeyo. Marka hawo badan la geliyo, waxay si xun u saameyn kartaa xoogga hoobiye.

Hydroxypropyl methylcellulose waxay dib u dhigi doontaa habka dejinta sibidhka, waxay hoos u dhigi doontaa habaynta iyo adkeynta sibidhka, waxayna kordhin doontaa wakhtiga furitaanka hoobiye si waafaqsan. Si kastaba ha noqotee, saameyntani uma roona hoobiye meelaha qabowga leh.

Sida walaxda silsiladda dheer ee polymer, hydroxypropyl methylcellulose waxay wanaajin kartaa waxqabadka isku-xidhka leh ee alaabta saldhigga iyada oo si buuxda loo ilaalinayo qoyaanka qoyaanka marka lagu daro nidaamka sibidhka.

Tilmaamaha ugu muhiimsan ee HPMC ee hoobiye waxaa ka mid ah: xajinta biyaha, dhumucdiyada, kordhinta wakhtiga dejinta, hawo qaadashada, hagaajinta xoogga curaarta, iwm.
