EipponCell® HEMC LH 6150M hydroxyethyl methyl cellulose waxay ka qaadataa meel muhiim ah oo ka mid ah waxyaabaha lagu daro ether-ka cellulose ee ku dhex jira saaxadda hoobiyaha budada qalalan.Tani hydroxyethyl methylcellulose waxay soo saartaa hawlo badan marka lagu daro qaababka hoobiye.Doorkeeda ugu muhiimsan ee hoobiye sibidhka waxay ku jirtaa haynta biyaha iyo dhumucdooda, dhinacyada muhiimka ah ee qaabeeya isticmaalka.
Marka laga soo tago doorarkeeda aasaasiga ah, dhexgalka hydroxyethyl methyl cellulose ee matrixka sibidhka waxa uu ku siinayaa awood caawimo ah.Kuwani waxay ka kooban yihiin fududaynta ku-biirinta hawada, dib-u-dhigista waqtiyada, iyo kor u qaadida xoogga curaarta xajinta, ka qaybqaata saameyn dhamaystiran oo ku saabsan waxqabadka hoobiye.
Haysashada biyaha waxay u soo baxdaa inay yihiin aasaaska saamaynta HEMC ee hoobiye.Waxyaabaha lagu daro ether-ka cellulose-ka waxay helayaan codsiyo kala duwan oo alaabooyin hoobiye ah ugu horreyn sababtoo ah awoodda ay u leedahay ilaalinta biyaha.Heerka haynta biyaha ee ay gaadhay HEMC waxa ay si adag ugu xidhan tahay arrimo ay ka mid yihiin viscosity, heerka beddelka, iyo cabbirka walxaha, kuwaas oo si wada jir ah gacan uga geysta waxtarkeeda.
Marka loo isticmaalo dhumuc ahaan ahaan, awoodda dhumucda hydroxyethyl methyl cellulose waxay si adag ugu xidhan tahay cabbirada sida heerka beddelka, cabbirka walxaha, viscosity, iyo heerka wax ka beddelka.Si ballaadhan marka loo hadlo, heerka sare ee beddelka iyo viscosity ee ether cellulose, oo ay weheliyaan cabbirro yar yar, saamaynta dhumucdiisuna waxay noqotaa mid aad u cad.
