CAS Helu 74-85-1 Mea Hoolako Ethylene. Nā ʻano o ka Ethylene
ʻO ka helu CAS 74-85-1 e pili ana iā Ethylene, he kinoea kala ʻole a hiki ke puhi ʻia e hana nui i ka ʻoihana petrochemical a me nā mea kanu lāʻau. Eia nā hiʻohiʻona nui o Ethylene:
Ke Kinohi Kinohi: C2H4
Kūlana Kino: Ma ka wela a me ke kaomi maʻamau, he kinoea ka ethylene.
Kaumaha Molekala: Ma kahi o 28.05 g/mol.
Puni paila: -103.7°C (-154.66°F) ma 1 lewa.
Lae hehee: -169.2°C (-272.56°F).
Māmā: Ma kahi o 1.18 kg/m³ ma STP, ʻoi aku ka māmā ma mua o ka ea.
Solubility: Hiki ke hoʻoheheʻe ʻia i ka wai a hiki ke hoʻoheheʻe ʻia i ka hapa nui o nā mea hoʻoheheʻe organik.
ʻAi ahi a me ka hana hou ʻana: ʻAi ʻia a hiki ke hana i nā hui pahū me ka ea. Hoʻopili me nā halogens, oxidizers, a me nā waikawa ikaika.
Nā hoʻohana o Ethylene:
** ʻOihana Petrochemical**: ʻO ka Ethylene kahi papa kūkulu hale mua i ka hana ʻana i nā kinikini he nui a me nā plastics, me ka polyethylene (ka plastic maʻamau o ka honua), ethylene glycol (hoʻohana ʻia i ka antifreeze a me ka polyester fibers), a me ka ethylene oxide (hoʻohana ʻia e hana ai. nā mea holoi a me nā plastic).
Mahiai: Hoʻohana ʻia ma ke ʻano he mea hoʻomaʻamaʻa no nā huaʻai a ma ke ʻano he mea hoʻoponopono ulu i ka horticulture ma muli o kāna hana ma ke ʻano he hormone mea kanu maoli, e hāpai ana i ka oʻo ʻana o nā hua, ke ʻano o ka pua, a me ka abscission.
Hana ʻia: Hoʻohana ʻia i ka hana ʻana i ka vinyl chloride (no PVC), styrene (no ka polystyrene), a me nā kinikona ʻē aʻe.
Nā manaʻo palekana:
Loaʻa i ke ahi a me ka pahū: ʻO ka hiki ke ʻā nui o Ethylene e pono e mālama pono i nā hana pale ahi a me ka ea kūpono i ka wā o ka lawelawe ʻana a me ka mālama ʻana.
ʻO ka ʻawaʻawa: ʻO ka loaʻa ʻana o nā mea kiʻekiʻe e hiki ke alakaʻi i ka noʻonoʻo, ke poʻo, a me ka asphyxiation i nā wahi nele o ka oxygen.
Ka hopena o ke kaiapuni: ʻOiai e hāʻule koke ana ka ethylene i ka lewa, ʻo kāna hana ʻana a me ka hoʻohana ʻana e kōkua i ka hoʻokuʻu ʻia ʻana o ke kinoea ʻōmaʻomaʻo ma o ka hoʻohana ʻana i ka ikehu a me ka hana ʻana i nā kemika pili.
Nā Punawai:
Hoʻokomo maʻamau nā mea hoʻolako i ka ethylene i nā hui petrochemical nui a me nā ʻoihana hoʻolaha kinoea kūikawā i nā kinoea ʻenehana. Hoʻohui pinepine kēia mau mea hoʻolako i nā hana e komo pū ana me ka unuhi ʻana o ka ethylene mai ka ʻaila ʻaila a i ʻole nā kahawai kinoea maoli, kona hoʻomaʻemaʻe ʻana, a me ka hāʻawi ʻana i nā mea kūʻai aku ma o nā pipelines, tankers, a cylinders, ma muli o ka nui a me nā koi hoʻohana hope. Ke ʻimi nei i ka ethylene, he mea koʻikoʻi ia e hui pū me nā mea hoʻolako kaulana e pili ana i ka palekana palekana a me nā kūlana kaiapuni, e hōʻoiaʻiʻo ana i ka maikaʻi o ka huahana a me nā hana mālama kuleana.
Inā makemake ʻoe i kēlā mau huahana, e ʻoluʻolu e hoʻokaʻaʻike mai iā mākou!
