HEC ee Daryeelka timaha

HEChydroxyethyl cellulosewaa wakiil samaynta filim wax ku ool ah, binder, dhumuc weyn, xasiliye iyo kala firdhiyaa buufinta timaha,timahadhexdhexaadiyeyaasha,daryeelka timahawakiilada iyo shambooyinka, waxyaalaha la isku qurxiyo. Dhumucdeeda iyo sifooyinka kolloid ee ilaalinta waxaa loo isticmaali karaa dareeraha iyo warshadaha saabuunta adag. HEC waxay si dhakhso ah u milmaysaa heerkul sare, taas oo dedejisa habka wax soo saarka waxayna hagaajinaysaa waxtarka wax soo saarka. Waxaa la og yahay in muuqaalka muuqda ee saabuunta ay ku jiraan HEC ay tahay in la hagaajiyo jilicsanaanta iyo ka ganacsiga dharka.

Waa maxay saamaynta hydroxyethyl cellulose ee maqaarka?

Hydroxyethyl cellulose wax saamayn ah kuma laha maqaarka. Hydroxyethyl cellulose waxaa si weyn loogu isticmaalaa waji-xidhaha wajiga, nadiifiyeyaasha, shaambooyinka iyo alaabada kale ee daryeelka. Wax dhib ah uma keento maqaarka, laakiin sidoo kale ma laha saameyn muuqata.

In la isku qurxiyo, solubility iyo viscosity of cellulose hydroxyethyl ayaa si buuxda u ciyaara doorka waxqabadka gaarka ah, sifooyinka tani xitaa in beddelka qabow iyo kulul ee xilliyada sidoo kale waxay sii wadi kartaa prototype ee isku qurxiyo, sidaas hydroxyethyl cellulose waxaa si ballaaran loo isticmaalaa in maaskarada. , Nadiifiyaha wejiga, dhaq ilaalinta alaabta sida shaambada, ma dhaawacayso maqaarka, laakiin ma laha saameyn muuqata. Waxaa si aad ah loogu isticmaalaa ka faa'iidaysiga saliidda, dhismaha, dawooyinka, badbaadada cuntada, dhar-samaynta iyo waraaqaha iyo qaybaha kale.

HEC waa cadaan ilaa iftiin jaale ah fibros ama budo adag, aan sun ahayn, dhadhamin,dhuuban ama adag budo ah oo lagu diyaariyey etherification of cellulose alkaline iyo ethylene oxide (ama chlorethanol). Waa eter cellulose milmaya aan ionic ahayn. Sababtoo ah HEC waxay leedahay dhumuc wanaagsan, ganaax, kala firidhsan, emulsification, adhesion, samaynta filimka, ilaalinta biyaha iyo bixinta kolloid ilaalin iyo sifooyin kale, ayaa si weyn loogu isticmaalay ka faa'iidaysiga saliidda, daahan, dhismaha, daawada iyo cuntada, dunta, samaynta waraaqaha iyo polymer falcelinta polymerization iyo qaybaha kale. Heerka baadhista ee 40 mesh ≥99%.

Ka taxadar isticmaalkaHEChydroxyethyl cellulose

Marka hore,HEChydroxyethyl cellulose waa in si joogto ah loo walaaqaa ka hor inta aan lagu darin, ilaa uu xalku noqdo mid hufan oo cad. Si tartiib ah ugu shub baaldiga isku dhafka ah, si degdeg ah ama meel weyn ha u gelin. Saddexaad, heerkulka heerkulka biyaha ayaa saameyn weyn ku leh milanka hydroxyethyl cellulose, markaa ka hor inta aan lagu darin waa in fiiro gaar ah loo yeesho heerkulka biyaha la isticmaalo. 4 sida ugu fog ee suurtogalka ah ee wakhtiga loo qoondeeyey gudahood baaxadda isticmaalka, sidoo kale ku biiri kartaa fungicides ah, horraanta shanaad ka dib markii processing of cellulose hydroxyethyl, guud ahaan ma fududa in la sameeyo clumps ama globular, sidaas darteed in isticmaalka hydroxyethyl cellulose waa in fiiro gaar ah. Habka saxda ah ee loo isticmaalo si loo si fiican u ciyaaro doorka hydroxyethyl cellulose.
