Hoʻohana
ʻO kekahi o nā hiʻohiʻona nui a me ka hoʻohana ʻana o ka ethylene glycol kona versatility e like me ka solvent. Ma ke ʻano he solubilizer pono a maikaʻi hoʻi, hoʻohana nui ʻia i nā ʻoihana like ʻole. ʻO kona hiki ke hoʻoheheʻe i nā ʻano mea like ʻole he mea nui ia i ka hana ʻana i nā polyesters synthetic. Inā pono ʻoe e hoʻoheheʻe i ka wai, nā lāʻau lapaʻau a i ʻole nā mea ʻē aʻe, hāʻawi nā glycols i ka solvency maikaʻi loa e hōʻoia i nā hopena maikaʻi loa no kāu kaʻina hana.
ʻO kekahi hiʻohiʻona ʻē aʻe o ka ethylene glycol ʻo kāna hana ma ke ʻano he antifreeze. Me kona wahi maloʻo haʻahaʻa, pale ia i ka hau mai ka hoʻokumu ʻana i ka ʻōnaehana hoʻoluʻu, e hoʻolilo iā ia i mea waiwai nui i nā hana antifreeze automotive. Mālama kēia hiʻohiʻona i kāu ʻenekini a me ka ʻōnaehana hoʻoluʻu e hoʻomau i ka hana ʻoiai i nā mahana sub-zero. Eia kekahi, ʻo kona haʻahaʻa haʻahaʻa i nā holoholona e hōʻoiaʻiʻo i ka hoʻohana palekana i nā ʻoihana ʻoihana a me nā noi home.
He kuleana koʻikoʻi ka Ethylene glycol i nā mea maka no ka synthesis o ka polyester. ʻO ia ke kumu kumu no ka hana polyester a loaʻa iā ia ke kūpaʻa wela maikaʻi a me nā waiwai mechanical. Inā makemake ʻoe i nā fiber synthetic, nā kiʻiʻoniʻoni a i ʻole nā resins, hāʻawi nā glycols i ke kumu no ka hana ʻana i nā mea hana kiʻekiʻe e kūpono i nā pono like ʻole o nā ʻoihana like ʻole.
I ka hōʻuluʻulu ʻana, ʻo ka ethylene glycol he hui multifunctional me ka solvency maikaʻi a me nā waiwai antifreeze, a he mea waiwai nui ia i ka hana ʻana i nā polyesters synthetic. ʻO kona ʻano kala ʻole, ʻaʻala ʻole, i hui pū ʻia me ka haʻahaʻa haʻahaʻa i nā holoholona, e hōʻoia i ka palekana a me ka pono i kāu noi. Hoʻohui maikaʻi ʻia ʻo Glycol me ka wai a me ka acetone, e hana ia i ka hopena kūpono loa no kāu mau mea hoʻoheheʻe a me nā pono antifreeze. E ʻike i nā pono maikaʻi loa o ka ethylene glycol a lawe i kāu kaʻina hana i nā kiʻekiʻe hou.
