Ethylene diglycol monoethyl ether CAS 111-90-0
Ethylene diglycol monoethyl ether waa dareere aan midab lahayn, hufan oo heerkulka qolka iyo cadaadiska. Waa dareere aan midab lahayn, biyo nuugaya oo deggan. Waxay leedahay ur dhexdhexaad ah oo macaan. Waa la qallafsan yahay biyaha, acetone, benzene, chloroform, ethanol, ether, pyridine, iwm. Waxay leedahay ur dhexdhexaad ah. Diethylene glycol ethyl ether waxaa inta badan loo isticmaalaa sida dareere loogu talagalay nitrocellulose, resins, rinjiga buufinta, midabada, iwm. Dhinaca kiimikooyinka wanaagsan, xaruntan waxaa loo isticmaali karaa mid ka mid ah maaddooyinka ku jira caanaha nadiifinta mashiinka baabuurta; Isku-dhafka dabiiciga ah, xaruntan waxaa lagu soo bandhigi karaa qaab-dhismeedka molecular ee qalabka shaqeynaya iyada oo loo marayo falcelinta esterification ee kooxaha hydroxyl iyo falcelinta beddelka nucleophilic.

1. Dahaarka iyo rinjiyada
Ethylene diglycol monoethyl ether ayaa loo isticmaali karaa sidii dareere. Qaababka dahaarka, waxay si wax ku ool ah u milmi kartaa resins, pigments iyo maaddooyinka kale. Tusaale ahaan, qaar ka mid ah dahaarka biyaha ku salaysan, waxay ka caawisaa resin in si siman loo kala firdhiyo, si dahaarka uu u yeesho dareere wanaagsan iyo waxqabadka dahaarka, taas oo hubinaysa in dahaarka uu samayn karo mid lebis ah oo rinji ah oo siman oo ku yaal dusha daboolan.
Diethylene glycol ethyl ether waxay gacan ka geysataa hagaajinta xawaaraha qalajinta ee daahan. Waxay hagaajin kartaa heerka uumiga dareeraha ee daahan si looga fogaado cilladaha filimka rinjiga ee uu keeno uumiga dareeraha degdega ah ama aad gaabis u ah, sida ifafaale diirka liimiga (qalabka si dhakhso ah ayuu u baxaa, dusha filimka rinjiga waa mid aan sinnayn) ama waqti aad u dheer qalajinta.
2. Warshadaha khadadka
Sida dareere khad ah, Ethylene diglycol monoethyl ether waxa loo isticmaalaa in lagu milo resins, dheehyada iyo maaddooyinka kale ee khadka si loo siiyo khad mug iyo dareere ku habboon. Tani waxay muhiim u tahay waxqabadka wareejinta khad inta lagu jiro habka daabacaadda, waxayna hubin kartaa in khadku si sax ah looga wareejiyo saxanka daabacaadda oo loo wareejiyo walxaha daabacaadda (sida warqad, filim caag ah, iwm.), samaynta qaabab cad oo dhalaalaya iyo qoraal.
Waxa kale oo ay wanaajin kartaa xasilloonida khad, waxay ka ilaalin kartaa khad roobaadka iyo kala-soocidda inta lagu jiro kaydinta, waxayna kordhin kartaa nolosha khad.
3. Nadiifinta iyo nadiifinta isticmaalka
Diethylene glycol monoethyl ether waa qayb nadiifin heer sare ah. Maaddaama Ethylene diglycol monoethyl ether ay leedahay milmayn wanaagsan oo dufanka, wasakhowga saliidda, iwm, waxaa loo isticmaali karaa in lagu nadiifiyo wasakhda saliidda ee meelaha birta ah. In wax soo saarka warshadaha, sida farsamaynta makaanikada, baabuurta wax soo saarka iyo warshadaha kale, waxaa loo isticmaalaa in lagu nadiifiyo saliidda processing, saliid anti-daxaladaha, iwm dusha qaybaha si loo hubiyo in dusha qaybo ka mid ah waa nadiif ah oo nadiif ah inta lagu guda jiro processing xiga ama kulan.
Waxa kale oo loo isticmaali karaa in lagu nadiifiyo qaybaha elektiroonigga ah. Awooddeeda lagu milo wasakhowga saliidda waxay si wax ku ool ah uga saari kartaa dufanka iyo wasakhda dusha sare ee qaybaha elektaroonigga ah. Waxaa intaa dheer, waxay leedahay isbeddel gaar ah waxayna si dhakhso ah u engejin kartaa nadiifinta ka dib. Kama tagi doono wasakh badan oo dusha sare ah ee qaybaha, si loo hubiyo waxqabadka qaybaha elektiroonigga ah.
4. Warshadaha daabacaadda dharka iyo rinjiyeynta
Kaaliyaha dharka ahaan, diethylene glycol monoethyl ether ayaa loo isticmaali karaa si loo hagaajiyo sifooyinka midabaynta ee dharka. Waxay ka caawin kartaa dheeha inay si fiican u galaan fiilooyinka dunta oo ay ka dhigaan midabaynta mid la mid ah. Tusaale ahaan, habka midabaynta ee dharka suufka ah, dharka polyesterka, iwm., waxaa loo isticmaalaa sida dheeha dheeha si loo hagaajiyo qoto dheer ee midabaynta iyo lebbiska.
Waxa kale oo loo isticmaali karaa habka dhamaystirka dharka si loo hagaajiyo waxqabadka wakiilka dhamaystirka, sida qayb ka mid ah walxaha dareeraha ah ee qaar ka mid ah wakiilada dhamaystirka jilicsan, si wakiilka dhamaystirku uu si fiican ugu dhejiyo dusha sare ee dharka, siinta dharka jilicsan oo jilicsan.
