Nadiifin-sare leh Diethylene Glycol Solvent 99.6%

Gaar ahaan: 230kg / durbaan

Diethylene glycol, oo caadi ahaan loo soo gaabiyo DEG oo si nidaamsan loogu magac daray 2,2'-oxydiethanol, waa dareere aan midab lahayn, ur lahayn, hygroscopic, viscopic ah oo leh dhadhan macaan. Alaabadayada tayada sare leh waxay gaartaa 99.6% nadiif ah, oo soo saarta waxqabadka gaarka ah ee wax soo saarka polyester-ka, qaabaynta ka-hortagga barafka, codsiyada humectant, iyo hababka warshadaha kala duwan ee u baahan glycol-karrin sare, biyo-miscible.

Sida ether-ka ugu fudud ee glycol ee ka soo jeeda ethylene oxide, diethylene glycol waxay leedahay kiimiko iyo astaamo jireed oo gaar ah oo ka sooca ethylene glycol iyo glycols sare. Xidhiidhka ether-ka ee ka dhexeeya labada unug ee ethylene glycol wuxuu bixiyaa awoodda dareeraha ee la xoojiyey ee xeryahooda dabiiciga ah, barta qaboojinta oo yaraatay, iyo sifooyinka viscosity ee wanaagsan. Joogitaanka labada kooxood ee hydroxyl terminal waxay awood u siinaysaa polyesterification, etherification, iyo falcelinta esterification, taageeridda wax soo saarka kala duwanaansho kala duwan.

Warshada xabagta polyester-ka ee aan dheregsanayn waxay ka dhigan tahay qaybta codsiga ee ugu weyn ee DEG, halkaas oo ay ugu adeegto sidii komonmer muhiim ah oo leh anhydride lab ah iyo anhydride phthalic. Ku darista diethylene glycol ee laf dhabarta polyester-ka waxay bixisaa dabacsanaan, iska caabin saameyn leh, iyo hagaajinta caabbinta biyaha marka la barbar dhigo resins-ku salaysan ethylene glycol. Guryahani waxay lama huraan u yihiin isku-dhafka fiber-glass-ku-xoojiyey, qolalka doonyaha, muraayadaha jidhka baabuurta, iyo haamaha kaydinta kiimikada ee u adkaysata daxalka. Darajada nadiifka sare waxay hubisaa kinetics polymerization joogto ah iyo waxqabadka ugu dambeeya.

Dheecaannada kulaylka ka-hortagga ah iyo wareejinta kulaylka, DEG waxay u shaqeysaa sidii qayb ka mid ah qaboojiyeyaasha la sameeyay, iyadoo bixisa ilaalin baraf ah iyo kor u qaadista karkarinta oo leh isbeddel hoose marka loo eego ethylene glycol. Hababka hygroscopic ee aadka u wanaagsan ee xarunta ayaa ka dhigaya mid qiimo leh sida humectant tubaakada, warqadaha, iyo farsamaynta dunta, ilaalinta nuxurka qoyaanka iyo ka hortagga jajabnaanta. Codsiyada dheeraadka ah waxaa ka mid ah isticmaalka balaastiigga ah ee cellulosic iyo resins synthetic, dareeraha dheeha iyo daabacaadda daabacaadda, wakiilka fuuq-baxa ee habka gaaska dabiiciga ah, iyo dhexdhexaadinta kiimikaad ee soo saarida morpholine iyo kuwa kale ee ka soo baxa.

Our 99.6% diethylene glycol saafi ah waxay la kulantaa qeexitaanno adag oo loogu talagalay acidity hooseeya, content biyaha ugu yar, midabka kantaroolka (Pt-Co), iyo ethylene glycol hooseeya iyo triethylene glycol wasakhaysan, hubinta wax soo saarka polyester-ka la isku halayn karo, waxqabadka humictant joogto ah, iyo soosaar tayo sare leh ee soosaarayaasha resin, soosaarayaasha glycol ee khaaska ah ee dawooyinka kiimikada codsiyada warshadaha dalbanaya.

Shirkaddayadu waxay si qoto dheer ugu hawlan tahay warshadaha kiimikada waxayna inta badan wax ka qabataa noocyo kala duwan oo alaabta ceeriin kiimikaad ah sida surfactants, kiimikooyinka ganaaxa ee saliidda, alaabta ceeriin ee aasaasiga ah, dareerayaasha organic, dhexdhexaadinta dawooyinka iyo sunta cayayaanka, wakiilada daaweynta biyaha, iyo cuntada lagu daro. Alaabooyinkeeda ayaa si weyn looga isticmaalaa warshado kala duwan.
