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

nā ʻano kemika

Ke ʻano kemika: (CH2OH)2 Kaumaha molekole: 62.068 CAS: 107-21-1 EINECS: 203-473-3 [5 Wahi hoʻoheheʻe: -12.9 ℃ Wahi paila: 197.3 ℃

Hoʻolauna huahana a me nā hiʻohiʻona

ʻO CH2OH 2, ʻo ia ka diol maʻalahi loa. He wai ʻono ʻole ka Ethylene glycol, ʻala ʻole, me ka ʻawaʻawa haʻahaʻa i nā holoholona. Hiki ke hoʻoheheʻe ʻia ka Ethylene glycol me ka wai a me ka acetone, akā he liʻiliʻi kona solubility i nā ethers. Hoʻohana ʻia ma ke ʻano he solvent, antifreeze a me ka synthetic polyester raw material. ʻO ka polymer o ka ethylene glycol, polyethylene glycol (PEG), he mea hoʻoulu hoʻoili pae a hoʻohana ʻia hoʻi i ka fusion cell

hoʻohana

Hoʻohana nui ʻia no ka hana ʻana i ka polyester, polyester, polyester resin, moisture absorbent, plasticizer, surface active agent, synthetic fiber, cosmetics a me nā mea pahū, a hoʻohana ʻia ma ke ʻano he solvent no nā dyes, inks, etc., ka hoʻomākaukau ʻana i ka mīkini antifreeze agent, gas dehydrating agent, manufacturing resin, hiki ke hoʻohana ʻia no cellophane, fiber, ili, adhesive wetting agent. Hiki iā ia ke hana i ka synthetic resin PET, fiber PET ʻo ia hoʻi ka polyester fiber, ʻāpana ʻōmole PET no ka hana ʻana i nā ʻōmole wai mineral a pēlā aku. Hiki ke hana i ka alkyd resin, glyoxal, etc., i hoʻohana ʻia hoʻi ma ke ʻano he antifreeze. Ma waho aʻe o ka hoʻohana ʻia ʻana he antifreeze no nā kaʻa, hoʻohana ʻia hoʻi no ka lawe ʻana i ka mana hoʻoluʻu ʻoihana, i kapa ʻia ʻo carrier refrigerant, a hiki ke hoʻohana ʻia ma ke ʻano he condensing agent e like me ka wai.
ʻO nā huahana moʻo Ethylene glycol methyl ether he mau mea hoʻoheheʻe organik kiʻekiʻe, e like me ka ʻīnika paʻi, ka mea hoʻomaʻemaʻe ʻoihana, ka uhi ʻana (pena nitro fiber, varnish, enamel), ka pā keleawe i uhi ʻia, ka paʻi ʻana a me ka hoʻoluʻu ʻana i nā mea hoʻoheheʻe a me nā mea hoʻoheheʻe; Hiki ke hoʻohana ʻia ma ke ʻano he mea maka no nā huahana kemika e like me nā mea waena pesticide, nā mea waena lāʻau lapaʻau a me ka wai brake synthetic. Ma ke ʻano he electrolytes no nā capacitors electrolytic, mea hoʻoheheʻe fiber kemika no ka tanning, a pēlā aku. Hoʻohana ʻia ma ke ʻano he mea kōkua textile, nā mea hoʻoheheʻe wai synthetic, a me ka hoʻomaʻemaʻe ʻana a me ka ʻaila i ka hana ʻana o nā mea maka desulfurizer.
Pono e hoʻomaopopo ʻia ka Ethylene glycol i ka wā e hoʻohana ʻia ai ma ke ʻano he refrigerant lawe:
1. Hoʻololi ke kiko hau me ka nui o ka ethylene glycol i loko o ka wai hoʻonā. Ke emi ka nui o ka 60%, emi ke kiko hau me ka piʻi ʻana o ka nui o ka ethylene glycol i loko o ka wai hoʻonā, akā ke ʻoi aku ka nui o ka 60%, piʻi ke kiko hau me ka piʻi ʻana o ka nui o ka ethylene glycol, a piʻi ka mānoanoa me ka piʻi ʻana o ka nui. Ke hiki ka nui i 99.9%, piʻi kona kiko hau i -13.2℃, ʻo ia ke kumu nui e hiki ʻole ai ke hoʻohana pololei i ka antifreeze i hoʻopaʻa ʻia (antifreeze mother liquid), a pono e huki i ka manaʻo o ka mea hoʻohana.
2. Loaʻa i ka Ethylene glycol ka hui hydroxyl, kahi e hoʻoheheʻe ʻia i ka waikawa glycolic a laila i ka waikawa oxalic, ʻo ia hoʻi, ka waikawa glycolic (oxalic acid), nona nā hui carboxyl 2, ke hana ia ma 80-90 ℃ no ka manawa lōʻihi. Hoʻopilikia mua ka waikawa Oxalic a me kāna mau huahana 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 lako. No laila, i ka hoʻomākaukau ʻana o ka antifreeze, pono e loaʻa kahi mea mālama e pale aku i ka pala o ke kila, ka alumini a me ka hoʻokumu ʻana o ka unahi.

pūʻolo a me ka halihali

B. Hiki ke hoʻohana ʻia kēia huahana,,25KG,200KG,1000KGBAERRLS.
C. E mālama pono i kahi i hoʻopaʻa ʻia ma kahi anu, maloʻo a me ka ea i loko. Pono e hoʻopaʻa pono ʻia nā ipu ma hope o kēlā me kēia hoʻohana ma mua o ka hoʻohana ʻana.
D. Pono e hoʻopaʻa pono 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 pū ʻana.
