Ethylene glycol, 1, 2-ethylenediol, EG no ka pōkole

ʻano kemika

Huina kemika: (CH2OH)2 Kaumaha molekalale: 62.068 CAS: 107-21-1 EINECS: 203-473-3 [5 Wehe hehee: -12.9 ℃ Puni paila: 197.3 ℃

Hoʻopuka huahana a me nā hiʻohiʻona

CH2OH 2, oia ka diol maalahi loa.ʻO ka Ethylene glycol he wai ʻono ʻole, ʻaʻala ʻole, wai ʻono me ka haʻahaʻa o ka ʻona i nā holoholona.Hiki ke hoʻoheheʻe ʻia ka Ethylene glycol me ka wai a me ka acetone, akā liʻiliʻi kona solubility i ka eter.Hoʻohana ʻia e like me ka solvent, antifreeze a me ka synthetic polyester raw material.ʻO ka polymer o ka ethylene glycol, polyethylene glycol (PEG), he mea hoʻololi hoʻololi hoʻololi a hoʻohana pū ʻia i ka hui pū ʻana.

hoʻohana

Hoʻohana nui ʻia no ka hana ʻana i ka polyester, polyester, polyester resin, moisture absorbent, plasticizer, surface active agent, synthetic fiber, cosmetics and explosives, a hoʻohana ʻia e like me ka solvent no nā dyes, inks, etc. hana resin, hiki ke hoʻohana ʻia no cellophane, fiber, ʻili, adhesive wetting agent.Hiki iā ia ke hana i ka resin synthetic PET, fiber PET ʻo ia ka polyester fiber, ʻāpana ʻōmole PET no ka hana ʻana i nā hue wai mineral a pēlā aku.Hiki ke hana i ka resin alkyd, glyoxal, a me nā mea ʻē aʻe, i hoʻohana ʻia e like me antifreeze.Ma kahi o ka hoʻohana ʻia ʻana e like me ka antifreeze no nā kaʻa, hoʻohana ʻia no ka lawe ʻana i ka mana hoʻoluʻu ʻenehana, i kapa ʻia ʻo ka mea hoʻoheheʻe lawe, a hiki ke hoʻohana ʻia e like me ka condensing agent e like me ka wai.
ʻO nā huahana Ethylene glycol methyl ether moʻo he mau mea hoʻoheheʻe kūlohelohe kiʻekiʻe, e like me ka paʻi ʻana i ka inika, ka mea hoʻomaʻemaʻe ʻoihana, ka uhi ʻana (nitro fiber pena, varnish, enamel), ke keleawe i uhi ʻia i ka pā, ka paʻi ʻana a me ke kala ʻana i nā solvents a me nā diluents;Hiki ke hoʻohana ʻia e like me nā mea maka no nā huahana kemika e like me nā pesticide intermediates, pharmaceutical intermediates a me synthetic brake fluid.E like me electrolytes no ka electrolytic capacitors, kemika fiber dyeing agent no ka tanning, etc. Hoʻohana 'ia e like me textile auxiliaries, synthetic wai dyes, a me ka fertilizer a me ka aila hoʻomaʻemaʻe i ka hana o desulfurizer maka mea.
Pono e ʻike ʻia ka Ethylene glycol ke hoʻohana ʻia ma ke ʻano he mea hoʻoheheʻe lawe:
1. Hoʻololi ke kiko maloʻo me ka neʻe ʻana o ka ethylene glycol i loko o ka wai.Ke emi iho ka helu ma lalo o 60%, e emi ana ka helu hau me ka piʻi ʻana o ka ʻike o ka ethylene glycol i loko o ka wai wai, akā inā ʻoi aku ka nui o ka ʻike ma mua o 60%, piʻi ka helu hau me ka piʻi ʻana o ka ethylene glycol, a me ka viscosity. piʻi me ka piʻi ʻana o ka manaʻo.Ke piʻi ka manaʻo i ka 99.9%, piʻi kona wahi maloʻo i -13.2 ℃, ʻo ia ke kumu nui e hiki ʻole ai ke hoʻohana pololei ʻia ka antifreeze concentrated (antifreeze mother liquid), a pono e huki i ka manaʻo o ka mea hoʻohana.
2. Loaʻa i ka Ethylene glycol ka hui hydroxyl, e hoʻoneʻe ʻia i ka waikawa glycolic a laila i ka waikawa oxalic, ʻo ia hoʻi, glycolic acid (oxalic acid), loaʻa nā hui carboxyl 2, ke hana ia ma 80-90 ℃ no ka manawa lōʻihi.ʻO ka waika Oxalic a me kāna mau huahana e hoʻopili mua i ka ʻōnaehana nerve waena, a laila ka puʻuwai, a laila nā puʻupaʻa.ʻO ka Ethylene glycol glycolic acid, e hoʻoulu ai i ka pala a me ka leakage o nā mea hana.No laila, i ka hoʻomākaukau ʻana i ka antifreeze, pono e loaʻa kahi preservative e pale ai i ka corrosion o ke kila, alumini a me ka hoʻokumu ʻana o ka unahi.

pūʻolo a me ka lawe ʻana

B. Hiki ke hoʻohana ʻia kēia huahana, 25KG, 200KG, 1000KGBAERRLS.
C. E kūʻai i sila ma kahi anuanu, maloʻo a me ka makani ma loko.Pono e hoʻopaʻa paʻa ʻia nā pahu ma hope o kēlā me kēia hoʻohana ma mua o ka hoʻohana ʻana.
D. Pono e hoʻopaʻa maikaʻi ʻia kēia huahana i ka wā o ka lawe ʻana e pale aku i ka makū, ka alkali ikaika a me ka waikawa, ka ua a me nā mea haumia ʻē aʻe mai ka hui ʻana.
