Soo bandhigidda badeecada iyo sifooyinka

CH2OH 2, kaas oo ah diol-ka ugu fudud. Ethylene glycol waa dareere macaan oo aan midab lahayn, ur lahayn, oo sun yar ku ah xayawaanka. Ethylene glycol waxaa lagu milmi karaa biyaha iyo acetone, laakiin milmidiisa ethers waa yar tahay. Waxaa loo isticmaalaa sidii dareere, ka-hortagga barafowga iyo walxo kale oo polyester ah oo macmal ah. Polymer-ka ethylene glycol, polyethylene glycol (PEG), waa kiciyaha wareejinta marxaladda waxaana sidoo kale loo isticmaalaa isku-darka unugyada.

isticmaal

Waxaa inta badan loo isticmaalaa sameynta polyester, polyester, resin polyester, nuugaya qoyaanka, balaastigeeye, wakiilka firfircoon ee dusha sare, fiber synthetic, qurxinta iyo walxaha qarxa, waxaana loo isticmaalaa dareere ahaan midabaynta, khad, iwm., diyaarinta wakiilka ka hortagga barafowga matoorka, wakiilka fuuq-baxa gaaska, resin wax soo saarka, waxaa sidoo kale loo isticmaali karaa cellophane, fiber, maqaar, wakiilka qoynta dhejiska. Waxay soo saari kartaa resin synthetic PET, fiber PET oo ah fiber polyester, dhalo jajab PET ah oo lagu sameeyo dhalooyinka biyaha macdanta iyo wixii la mid ah. Waxay sidoo kale soo saari kartaa resin alkyd, glyoxal, iwm., oo sidoo kale loo isticmaalo ka hortagga barafowga. Marka laga soo tago in loo isticmaalo ka hortagga barafowga baabuurta, waxaa sidoo kale loo isticmaalaa gaadiidka awoodda qaboojinta warshadaha, oo guud ahaan loo yaqaan qaboojiyaha side, waxaana sidoo kale loo isticmaali karaa wakiil isku-ururin sida biyaha.
Badeecadaha taxanaha Ethylene glycol methyl ether waa dareereyaal tayo sare leh oo dabiici ah, sida khad daabacan, wakiilka nadiifinta warshadaha, dahaarka (rinjiga nitro fiber, varnish, dhaldhalaalka), saxanka naxaasta lagu dahaadhay, dareeraha daabacaadda iyo rinjiyeynta iyo waxyaabaha lagu qaso; Waxaa loo isticmaali karaa walxo ceeriin ah oo loogu talagalay alaabada kiimikada sida kuwa sunta cayayaanka dila, kuwa daawada iyo dareeraha biriiga ee synthetic-ga ah. Sida elektrolytyada loogu talagalay capacitors-ka elektiroonigga ah, wakiilka rinjiyeynta fiber-ka kiimikada ee loogu talagalay midabaynta, iwm. Waxaa loo isticmaalaa kaaliyeyaal dhar ah, midabyo dareere ah oo macmal ah, iyo sidoo kale bacriminta iyo sifeynta saliidda ee wax soo saarka walxaha ceeriin ee desulfurizer.
Ethylene glycol waa in la ogaadaa marka loo isticmaalo sida qaboojiyaha:
1. Barta barafku way isbeddeshaa marka la isku daro ethylene glycol ee ku jirta xalka biyaha. Marka isku-darka uu ka hooseeyo 60%, barta barafku way yaraataa marka la isku daro ethylene glycol ee ku jirta xalka biyaha, laakiin marka isku-darka uu ka bato 60%, barta barafku way korodhaa marka la isku daro ethylene glycol, dheellitirkuna wuu kordhaa marka la isku daro. Marka isku-darka uu gaaro 99.9%, barta barafku waxay u kacdaa -13.2℃, waana sabab muhiim ah oo aan si toos ah loogu isticmaali karin antifreeze-ka xooggan (dareere hooyada antifreeze ah) waana inay soo jiidataa dareenka isticmaalaha.
2. Ethylene glycol wuxuu ka kooban yahay kooxda hydroxyl, kaas oo lagu oksaydhi doono glycolic acid ka dibna loo rogi doono oxalic acid, taas oo ah, glycolic acid (oxalic acid), oo ka kooban 2 kooxood oo carboxyl ah, marka ay shaqeyso 80-90 ℃ muddo dheer. Oxalic acid iyo wax soo saarkeeda waxay marka hore saameeyaan habdhiska dhexe ee neerfaha, ka dibna wadnaha, ka dibna kelyaha. Ethylene glycol glycolic acid, taasoo keenta daxalka iyo daadashada qalabka. Sidaa darteed, diyaarinta ka hortagga qabowga, waa inay jirtaa ilaaliye si looga hortago daxalka birta, aluminiumka iyo sameynta miisaanka.

xirmada iyo gaadiidka

B. Badeecadan waa la isticmaali karaa,,25KG,200KG,1000KGBAERRLS.
C. Ku kaydi meel qabow, qalalan oo hawo leh gudaha. Weelasha waa in si adag loo xidhaa ka dib isticmaal kasta ka hor inta aan la isticmaalin.
D. Badeecadan waa in si fiican loo xiraa inta lagu jiro rarista si looga hortago qoyaanka, alkali iyo aashitada xooggan, roobka iyo wasakhda kale ee isku dhafan.
