Saamaynta heerka beddelka (DS) ee tayada HEC

HEC (hydroxyethyl cellulose) waa polymer aan-ionic ahayn, biyo-milmi kara oo si weyn loogu isticmaalo warshado kala duwan sida daryeelka shakhsi ahaaneed, daawooyinka, iyo cuntada sida dhumuc, xidhidh, iyo wakiilka xasilinta.Heerka beddelka (DS) waa halbeeg muhiim ah oo si weyn u saameyn kara sifooyinka iyo waxqabadka HEC.

Heerka beddelka waxa loola jeedaa celceliska tirada kooxaha hydroxyethyl ee ku dheggan unug kasta oo anhydroglucose ah oo ah laf dhabarta cellulose.Si kale haddii loo dhigo, waxay cabbiraysaa ilaa xadka unugyada cellulose lagu beddelay kooxaha hydroxyethyl.

Saamaynta heerka beddelka ee tayada HEC waa mid muhiim ah.Guud ahaan, marka heerka beddelka uu kordho, milanka HEC ee biyaha ayaa kordha, iyo viscosity-kiisu hoos u dhaco.HEC oo leh shahaado sare oo beddelaad ah ayaa leh aragti hoose, waana ku milmay biyaha.Tani waa sababta oo ah kooxaha hydroxyethyl waxay carqaladeeyaan isku xidhka hydrogen ee u dhexeeya silsiladaha cellulose, taasoo keenta qaab-dhismeed furfuran oo dabacsan.

Waxaa intaa dheer, heerka sare ee beddelka ayaa hagaajin kara xasiloonida kulaylka ee HEC oo kordhinaysa caabbinta hoos u dhaca enzymatic.Si kastaba ha noqotee, beddelaad heer sare ah oo aad u sarreeya waxay u horseedi kartaa hoos u dhac ku yimaada miisaanka molecular iyo luminta sifooyinka asalka ah ee laf-dhabarka cellulose, taas oo saameyn karta waxqabadka guud ee HEC.

Marka la soo koobo, heerka beddelku waa halbeeg muhiim ah oo si weyn u saameyn kara sifooyinka iyo waxqabadka HEC.Heerarka sare ee beddelka ayaa hagaajin kara milanka iyo xasilloonida kulaylka ee HEC, laakiin heerka xad-dhaafka ah ee beddelka ayaa u horseedi kara luminta sifooyinka asalka ah ee laf-dhabarka cellulose, taas oo saameyn karta waxqabadka guud ee HEC.
