Heerka qurxinta HEC

Darajada qurxintaHEC 

Hydroxyethyl cellulose, oo loo yaqaan HEC, muuqaalka cad ama iftiin huruud ah oo adag ama budo adag, aan sun iyo dhadhan lahayn, waxaa iska leh ether-ka cellulose aan-ionic ahayn. Hydroxyethyl cellulose si sahal ah bay ugu milmi kartaa biyaha, labadaba qabow iyo biyo kululba waa la kala diri karaa, xalalka aqueous ma laha sifooyin jel, wuxuu leeyahay adhesion wanaagsan, caabbinta kulaylka, aan milmin guud ahaan dareerayaasha organic. Hydroxyethyl cellulose waa ether-cellulose-cellulose-biyood-ku-milmi kara oo muhiim ah oo ka hooseeya karboxymethyl cellulose iyo hydroxypropyl methyl cellulose ee suuqa adduunka.

 

Heerkulka qurxinta HEC Hydroxyethyl cellulose hydroxyethyl cellulose waa wakiil samaynta filim wax ku ool ah, koollo, dhumuc weyn, xasiliye iyo kala firdhisan shaambo, buufinta timaha, dhexdhexaadiyaha, daryeelka timaha iyo qurxinta. Budada lagu dhaqo waa nooc ka mid ah wasakhda dib-u-dejinta; Saabuunta ka kooban hydroxyethyl cellulose waxay leedahay sifada muuqata ee hagaajinta jilicsanaanta iyo caleenta dharka.

 

Heerka qurxinta HEC Hydroxyethyl cellulose diyaarinta habka waa in la geliyo saxarka alwaax, suuf suuf ah iyo falcelinta sodium hydroxide, si aad u hesho sheyga alkali cellulose sida alaabta ceeriin, ka dib markii la jejebiyey galay kiliyaha falcelinta, hoos xaaladaha vacuum ee nitrogen, iyo ku biiraan Epoxy ethane falcelinta dareeraha cayriin waxay ahayd, markeeda ku dar ethanol, acetic acid, glioxal, nadiifinta, dhexdhexaadinta iyo falcelinta gabowga

Heerarka qurxinta HEC Hydroxyethyl cellulose la dhumucdiisuna, bonding, emulsion, ganaax, film samaynta, haynta biyaha, anti-daxalka, xasiloonida iyo sifooyin kale, waxaa si ballaaran loo isticmaali karaa in dareeraha qodista saliidda wakiilka dhumu, kala firdhiyey, rinjiga iyo khad alaabta dhumucdiisuna, xasiliyaha, xabagta, wax soo saarka caag ah ee kala firdhiso, wakiilka cabbirka dunta, qalabka dhismaha sida sibidhka iyo gypsum binder, dhumuc weyn, wakiilka biyaha haynta, Suspending wakiilka iyo surfactant ee alaabta maalinlaha ah ee kiimikooyinka, wakiilka sii daayo joogtada ah ee beerta farmashiyaha, daahan filim ee kiniiniga, blocker agabka qalfoofka, xabagta iyo xasilinta warshadaha elektiroonigga ah, iwm.

Suuqa Shiinaha, codsiga hydroxyethyl cellulose wuxuu inta badan ku urursan yahay dahaarka, kiimikooyinka maalinlaha ah, batroolka iyo warshadaha kale, iyo in ka yar qaybaha kale. Intaa waxaa dheer, wax soo saarka hydroxyethyl cellulose ee Shiinaha ayaa inta badan ah alaabooyinka hooseeya, codsigeeduna wuxuu inta badan ku urursan yahay daaha-hooseeya iyo alaabta kiimikada maalinlaha ah. Suuqa-dhamaadka sare, tirada shirkadaha khuseeya ee Shiinaha waa yar yahay, wax soo saarka waa ku filan, iyo ku tiirsanaanta dibadda waa weyn. Iyada oo ay wadaan dib-u-habaynta dhinaca sahayda iyo siyaasadaha ilaalinta deegaanka, qaab dhismeedka warshadaha hydroxyethyl cellulose ee Shiinaha ayaa si joogto ah u hagaajinaya oo kor u qaadaya, iyo heerka deegaan ee suuqa-dhamaadka sare ayaa sii wadi doona inuu horumaro mustaqbalka.

HEC Hydroxyethyl cellulose waa sheyga ether cellulose muhiim ah oo kaalinta saddexaad ka galay wax soo saarka iyo iibinta caalamiga ah. Waa cellulose aan ionic ahayn oo biyaha milmi kara, kaas oo si weyn loogu isticmaali karo Batroolka, rinjiga, khad daabacaadda, dunta, qalabka dhismaha, kiimikooyinka maalinlaha ah, dawooyinka, qalabka elektaroonigga ah iyo warshadaha kale, oo leh meel ballaadhan oo horumarineed. Iyadoo ay sabab u tahay baahida, wax soo saarka hydroxyethyl cellulose ee Shiinaha ayaa kor u kacaya. Iyada oo la cusboonaysiinayo isticmaalka iyo adkaynta siyaasadaha ilaalinta deegaanka, warshaduhu waxay u kobcayaan heer-sare. Shirkadaha aan la socon karin xawaaraha horumarka mustaqbalka ayaa si tartiib tartiib ah meesha looga saari doonaa.

Hydroxyethyl cellulose ee alaabta la isku qurxiyo, alaabta daryeelka maqaarka waa doorka ugu weyn ee timaha qaboojiyaha, wakiilka samaynta filimka, emulsifying stabilizer, koollada, khatarta khatarta ah waa 1, xad ammaan ah, waxay ku nasan kartaa in la isticmaalo, haweenka uurka leh guud ahaan wax saameyn ah kuma yeelan, hydroxyethyl cellulose ma laha wax finan keena .

Hydroxyethyl cellulose waa xabag polymer synthetic ah oo loo isticmaalo qurxinta sida qaboojiyaha maqaarka, wakiilka sameynta filim iyo antioxidant.

 

Arrimaha la xuso marka la isticmaalayoqurxintadarajoHECHydroxyethyl cellulose:

1. Kahor iyo ka dib marka lagu daro heerka qurxinta HEC hydroxyethyl cellulose, walaaqaya waa in la sii wadaa ilaa xalku si buuxda u hufan yahay oo cad yahay.

2. Si tartiib ah ugu xoori heerka qurxinta HEC hydroxyethyl cellulose haanta isku dhafka ah. Ha ku darin xaddi badan ama si toos ah ha u gelin haanta isku dhafka ah.

 

3. Kala-soocida heerka qurxinta HEC hydroxyethyl cellulose waxay si cad u la xiriirtaa heerkulka biyaha iyo qiimaha PH, markaa fiiro gaar ah waa in la bixiyaa.

4. Waligaa walxo alkaline ah ha ku darin isku darka ka hor inta aan budada hydroxyethyl cellulose lagu qaboojin biyo. Kordhinta qiimaha PH ka dib kululaynta waxay caawisaa inay milmaan.

5. Ilaa inta ay suurtogal tahay, ku dar caariyaysi hore.

6. Markaad isticmaalayso heerka viscosity-ga sare ee isqurxinta HEC hydroxyethyl cellulose, fiirsashada khamriga hooyadu waa inaanay ka badnaan 2.5-3%, haddii kale khamriga hooyadu way adagtahay in la shaqeeyo. Hydroxyethyl cellulose ee la daaweeyay ka dib guud ahaan ma fududa in la sameeyo clumps ama spheres, sidoo kale ma samayn doonto kolloysyada wareegsan ee aan milmi karin ka dib marka lagu daro biyo.
