Ethylene glycol, 1, 2-ethylenediol, EG mu magambo ahinnye

imiterere y'ibinyabutabire

Formule y'ibinyabutabire: (CH2OH)2 Uburemere bwa molekile: 62.068 CAS: 107-21-1 EINECS: 203-473-3 [5 Aho gushonga: -12.9 ℃ Aho kubira: 197.3 ℃

Intangiriro y'ibicuruzwa n'ibiranga

CH2OH 2, ari yo diol yoroshye cyane. Ethylene glycol ni amazi adafite ibara, adafite impumuro, aryoshye kandi afite uburozi buke ku nyamaswa. Ethylene glycol ishobora gushonga hamwe n'amazi na acetone, ariko gushonga kwayo muri ethers ni guke. Ikoreshwa nk'ibikoresho fatizo bya polyester, anti-konjesha na synthetic. Polymer ya ethylene glycol, polyethylene glycol (PEG), ni catalyst yo kohereza ibintu mu buryo bw'ingufu kandi ikoreshwa no mu guhuza uturemangingo.

gukoresha

Ikoreshwa cyane cyane mu gukora polyester, polyester, polyester resin, ifata ubushuhe, pulasitiki, igikoresho gikora ku buso, fibre y’ubukonje, amavuta yo kwisiga n’ibisasu, kandi ikoreshwa nk’umusemburo w’irangi, wino, nibindi, gutegura imashini irwanya ubukonje, imashini ikuraho amazi mu mwuka, gukora resin, ishobora kandi gukoreshwa muri cellophane, fibre, uruhu, imashini itose. Ishobora gukora resin y’ubukonje PET, fibre PET ari yo fibre ya polyester, PET yo gukata amacupa yo gukora amacupa y’amazi y’ubutare nibindi. Ishobora kandi gukora resin ya alkyd, glyoxal, nibindi, ikoreshwa kandi nk’irwanya ubukonje. Uretse gukoreshwa nk’irwanya ubukonje ku modoka, inakoreshwa mu gutwara ubushobozi bwo gukonjesha mu nganda, muri rusange yitwa refrigerant itwara ibintu, kandi ishobora no gukoreshwa nk’imashini igabanya ubukonje nk’amazi.
Ibicuruzwa bya ethylene glycol methyl ether ni organic solvents nziza cyane, nk'iwino icapa, isuku y'inganda, irangi (irangi rya nitro fibre, varnish, enamel), plaque itwikiriwe n'umuringa, solvents icapa kandi igasiga irangi n'ibindi bivange; Ishobora gukoreshwa nk'ibikoresho fatizo mu bicuruzwa bya shimi nk'imiti yica udukoko, imiti ikoreshwa mu buvuzi n'amazi ya feri ya sintetike. Nk'ibinyabutabire bya electrolytic capacitors, chemical fibre coloring agent yo gusiga irangi mu ruhu, nibindi. Ikoreshwa nk'ibikoresho by'imyenda, amarangi y'amazi ya sintetike, ndetse no gutunganya ifumbire n'amavuta mu gukora ibikoresho fatizo bya desulfurizer.
Ethylene glycol ikwiye kwitabwaho iyo ikoreshejwe nk'ikintu gikonjesha:
1. Igihe cyo gukonjesha kirahinduka bitewe n’ubwinshi bwa ethylene glycol mu gisubizo cy’amazi. Iyo ubwinshi buri munsi ya 60%, igihe cyo gukonjesha kiragabanuka bitewe n’ubwinshi bwa ethylene glycol mu gisubizo cy’amazi, ariko iyo ubwinshi burenze 60%, igihe cyo gukonjesha kiriyongera bitewe n’ubwinshi bwa ethylene glycol, kandi ubukana buriyongera bitewe n’ubwinshi bw’igisubizo. Iyo ubwinshi bugeze kuri 99.9%, igihe cyo gukonjesha kiriyongera kugera kuri -13.2°C, iyi ikaba ari impamvu ikomeye ituma anti-konjesha (anti-konjesha mother liquid) idashobora gukoreshwa mu buryo butaziguye, kandi igomba gukurura abayikoresha.
2. Ethylene glycol irimo itsinda rya hydroxyl, rizahinduka aside glycolic hanyuma rigahinduka aside oxalic, ni ukuvuga aside glycolic (aside oxalic), ririmo amatsinda 2 ya karubokisili, iyo rikora kuri 80-90 ℃ igihe kirekire. Aside oxalic n'ibiyikomokaho bigira ingaruka mbere ku mitsi yo hagati, hanyuma umutima, hanyuma impyiko. Aside ethylene glycol glycolic, ituma ibikoresho bigwa nabi. Kubwibyo, mu gutegura antikonjeze, hagomba kubaho ikintu kirinda kwangirika kw'icyuma, aluminiyumu no kurema igipimo.

gupakira no gutwara

B. Iki gicuruzwa gishobora gukoreshwa, 25KG, 200KG, 1000KGBAERRLS.
C. Bika ahantu hakonje, humutse kandi hafite umwuka mwiza mu nzu. Ibikoresho bigomba gufungwa neza nyuma ya buri gihe mbere yo kubikoresha.
D. Iki gicuruzwa kigomba gufungwa neza mu gihe cyo kugitwara kugira ngo hirindwe ubushuhe, alkali na aside nyinshi, imvura n'indi myanda kuvanga.
