Hydroxypropyl methylrcellellase, 28-30% chistoxyl, 7-12% hydroxypropyl

Faahfaahinta "28-30% Methoxyl" iyo "7-12% hydroxypropyl" Tixraac heerka beddelkaHydroxypropyl methylrcellulose(HPMC). Qiimayaashani waxay muujinayaan illaa xaddiga cudurka unugyada asalka ah ee unugyada loo yaqaan 'cellylose polymoner' ee kimikalku si kimikal ah looga beddelay chithoxyl iyo kooxaha hydroxypropyl.

1. 28-30% Methoxyl:
   • Tani waxay muujineysaa in, celcelis ahaan, 28-30% ee kooxaha Hydroxyl kooxaha hydroxyl ee molecule molecule-ka maskaxda lagu beddelay Kooxaha methoxyl (-cho3) ayaa loo soo bandhigayaa si loo kordhiyo biyaha ku jirta hydrophobis ee polymer.
2. 7-12% hydroxypropyl:
   • Tani waxay muujineysaa in, celcelis ahaan, 7-12% ee kooxaha Hydroxyl ee asalka ah ee ku yaal molecule molecule molecule-ka maskaxda lagu beddelay kooxaha hydroxypropyl. Kooxaha hydroxypropyl (boch2chohchch3) ayaa la soo bandhigayaa si kor loogu qaado jilitaanka biyaha oo wax ka beddelo astaamaha kale ee jidhka iyo kiimikada ee polymer.

Heerka wax lagu beddelo wuxuu saameyn ku yeeshaa astaamaha HPMC iyo wax qabadkiisa codsiyada kala duwan. Tusaale ahaan:

• Cudurka cirka sare ee Methoxyl guud ahaan wuxuu kordhiyaa hydrophobicity-ka polymer, oo saameyn ku leh jilitaanka biyaha iyo guryaha kale.
• Nuxurka biyaha badan ee hydroxypropyl wuxuu kor u qaadi karaa xaruusta biyaha iyo astaamaha filimka ee HPMC.

Xeerarkan ayaa muhiim u ah ku-habboonaanta HPMC si ay u buuxiyaan shuruudaha gaarka ah ee warshadaha kala duwan. Tusaale ahaan, warshadaha dawooyinka, doorashada fasalka HPMC oo leh heerar gaar ah oo ku beddela ayaa saameyn ku yeelan kara astaamaha loo sii daayo daroogada ee qaababka kiniiniga. Wershadaha dhismaha, waxay saameyn ku yeelan kartaa haynta biyaha iyo astaamaha guryaha ee alaabada ku saleysan sibidhka.

Soo-saareyaashu waxay soo saaraan heerar kala duwan oo ah HPMC oo leh heerar kala duwan oo ah beddelidda si ay ula kulmaan baahiyaha kala duwan ee codsiyada kaladuwan. Markii la isticmaalayo HPMC ee qaababka, waxaa muhiim u ah qaabeenaha si ay uga fiirsadaan darajada gaarka ah ee HPMC ee la jaan qaada guryaha la doonayo iyo astaamaha waxqabadka ee dalabka loogu talagalay.
