Ethylene glycol CAS 107-21-1 mea hoʻopuka

ʻO ka wehewehe pōkole:

ʻO ka Ethylene glycol kahi mea hoʻohuihui me ke ʻano (CH2OH)2.Hoʻohana nui ʻia ia no nā kumu ʻelua, ma ke ʻano he mea maka i ka hana ʻana i nā fibers polyester a no nā hana antifreeze.He wai ʻaʻala ʻole, waihoʻoluʻu, ʻono ʻono, wai viscous.

E hoʻouna i ka leka uila iā mākou

Hoʻohana Huahana

1. Mea ho'olili a me ka wela:ʻO ka hoʻohana nui ʻana o ka ethylene glycol ma ke ʻano he antifreeze agent i loko o ka mea hoʻomaha ma ka laʻana, nā kaʻa a me nā ʻōnaehana ea.

2. Anti-freeze:Hoʻohana ʻia ma ke ʻano he wai de-icing no nā pale makani a me nā mokulele, ma ke ʻano he antifreeze i nā ʻenekini kaʻa.

3. Ka mua i nā polymers:I loko o ka ʻoihana plastik, he mea nui ka ethylene glycol i nā fiber polyester a me nā resins.ʻO ka polyethylene terephthalate, i hoʻohana ʻia no ka hana ʻana i nā ʻōmole plastik no nā mea inu ʻoluʻolu, ua hoʻomākaukau ʻia mai ka ethylene glycol.

4. Mea hoʻoheheʻe wai:Hoʻohana ʻia i ka ʻoihana kinoea maoli e wehe i ka mahu wai mai ke kinoea maoli ma mua o ka hana hou ʻana.

5. Hoʻokaʻawale i ka wai:Hoʻohana ʻia e pale i ka hoʻokumu ʻana o nā clathrates kūlohelohe (hydrates).
