Ethylene (C2H4)

Nā palena ʻenehana

Ma lalo o nā kūlana maʻamau, ʻo ka ethylene he kala ʻole, a ʻala iki ke kinoea lapalapa me ka mānoanoa o 1.178g/L, ʻoi aku ka liʻiliʻi ma mua o ka ea.ʻAneʻane hiki ʻole ke hoʻoheheʻe ʻia i ka wai, ʻaʻole hiki ke hoʻoheheʻe ʻia i ka ethanol, a hiki ke hoʻoheheʻe iki ʻia i ka ethanol, ketones, a me benzene., Hiki ke hoʻoheheʻe ʻia i ka etera, hiki ke hoʻoheheʻe ʻia i loko o nā mea hoʻoheheʻe organik e like me ka carbon tetrachloride.Ethyleneʻo ia kekahi o nā huahana kemika me ka nui loa o ka huahana ma ka honua.ʻO ka ʻoihana ethylene ke kumu o ka ʻoihana petrochemical.ʻOi aku ka nui o nā huahana Ethylene ma mua o 75% o nā huahana petrochemical a noho i kahi kūlana koʻikoʻi i ka ʻoihana aupuni.Ua noʻonoʻo ka honua i ka hana ʻana o ka ethylene ʻo ia kekahi o nā hōʻailona koʻikoʻi e ana i ka pae hoʻomohala o ka ʻoihana petrochemical o ka ʻāina.ʻO ka Ethylene he mea koʻikoʻi koʻikoʻi kemika kumu, hoʻohana nui ʻia i ka hana ʻana i ka polyethylene, ethylene propylene rubber, polyvinyl chloride, a pēlā aku.Ma keʻano o nā mea synthetic, hoʻohana nuiʻia i ka hanaʻana i ka polyethylene, vinyl chloride, etc.;ma ke ʻano o ka synthesis organik, hoʻohana nui ʻia i ka synthesis o ka ethanol, ethylene oxide, ethylene glycol, acetaldehyde, a me propylene.ʻO nā ʻano mea like ʻole e like me ka aldehydes a me kā lākou mea hoʻohui;ma o ka halogenation, hiki iā ia ke hana i ka chloroethylene, chloroethane, bromoethane, etc. Hoʻohana nui ʻia ka Ethylene ma ke ʻano he kinoea maʻamau no nā mea analytical i nā ʻoihana petrochemical;hoʻohana ʻia ma ke ʻano he kinoea hoʻomaʻamaʻa kūlohelohe no nā hua e like me nā ʻalani piko, nā tangerines, maiʻa, a pēlā aku;hoʻohana ʻia i ka synthesis o nā lāʻau lapaʻau a me nā mea ʻenehana kiʻekiʻe;hoʻohanaʻia i ka hanaʻana i ke aniani kūikawā no kaʻoihana kaʻa;hoʻohana ʻia e like me ka refrigerant, ʻoi loa i nā mea kanu liquefaction LNG.E mālama i ka mālama ʻana: E kūʻai i loko o kahi hale kūʻai anuanu.E mālama i ke ahi a me nā kumu wela.ʻAʻole pono ka mahana o ka mālama ʻana ma mua o 30 ° C.Pono e mālama ʻokoʻa ʻia mai nā oxidants a me nā halogens, a pale i ka waiho ʻana.E hoʻohana i nā kukui pahū a me nā keʻena ea.ʻAʻole ʻae ʻia ka hoʻohana ʻana i nā mea hana mechanical a me nā mea hana e pili ana i nā huna ahi.Pono e hoʻolako ʻia ka wahi e mālama ai me nā lako lapaʻau ulia pōpilikia.

Noi:

①Kemika:

Ma waena o ka ʻoihana kemika a me ka hana ʻana i nā plastics

② Mea inu meaʻai:

ʻO ka ʻō ʻana o nā hua, ʻoi aku ka maiʻa..

③Keaniani:

He aniani kūikawā no ka ʻoihana kaʻa (ke aniani kaʻa).

④ Hana:

ʻOki metala, wiliwili a me High Velocity Thermal Spraying.

⑤Refrigerant:

ʻO ka mea hoʻoheheʻe ma nā mea kanu LNG liquefaction.

⑥Ka Paʻa Paʻa:

Hoʻohana ʻia i ka ʻohi ʻana i ka lāʻau.

Pūʻolo maʻamau:

Pōmaikaʻi:

①Maʻemaʻe kiʻekiʻe, hale hana hou loa;

②Ka mea hana palapala ISO;

③Hoʻouna wikiwiki;

④ Pūnaehana loiloi pūnaewele no ka mālama maikaʻi ʻana i kēlā me kēia pae;

⑤Ke koi kiʻekiʻe a me ke kaʻina hana no ka mālama ʻana i ka cylinder ma mua o ka hoʻopiha ʻana;
