Hydroxyethyl Methyl Cellulose (HEMC)

Hydroxyethyl methyl cellulose (HEMC) waa eter cellulose ah oo ka soo jeeda cellulose dabiiciga ah.Waa polymer-ka-milmi-biyoodka aan-ionic-ka ah oo si weyn loogu isticmaalo warshado kala duwan, oo ay ku jiraan dhismaha, daawooyinka iyo daryeelka shakhsi ahaaneed, sababtoo ah sifooyinka biyaha ilaalinta, dhumucda, xasilloonida, sameynta filimka iyo iswaafajinta.Hydroxyethyl methyl cellulose waxaa sameeyay falcelinta methyl chloride oo leh cellulose alkali ah, ka dibna waxaa lagu sii falceliyaa ethylene oxide si loo soo bandhigo hydroxyethyl silsiladda ugu weyn ee cellulose.Polymer-ka soo baxay wuxuu isku xiraa kooxaha hydroxyethyl iyo methyl cellulose, taas oo siinaya waxyaabo gaar ah iyo faa'iidooyin.Hydroxyethyl methyl cellulose waxay leedahay wax qabad wanaagsan oo xajin ah, waxaa loo isticmaali karaa wax soo saarka biyaha haynta muddada dheer, sida sibidhka, hoobiye iyo qalabka kale ee dhismaha.Hydroxyethyl methyl cellulose (HEMC) waxay kordhisaa viscosity iyo xasiloonida dareerayaasha, jelka, iyo kiriimyada.Tani waxay ka dhigtay shay caan ka ah alaabta daryeelka shakhsi ahaaneed sida shaambada, qaboojiyaha iyo labeennada, iyo sidoo kale daawooyinka iyo cuntooyinka.Hydroxyethyl methyl cellulose (HEMC) waxay samayn kartaa filim khafiif ah oogada alaabta, sidaas darteed waxay siinaysaa caqabad ka soo horjeeda arrimo dibadda ah.
