Helu CAS 74-86-2 Mea Hoʻolako Ethyne. Kūʻai nui ʻo Ethyne maʻemaʻe.
ʻO ka helu CAS 74-86-2 e pili ana iā Ethyne, i ʻike mau ʻia ʻo Acetylene, he kinoea kala ʻole a hiki ke hoʻohana nui ʻia i nā kaʻina hana ʻenehana. Eia kekahi mau hiʻohiʻona nui o ka acetylene:
Hua'ōlelo Kimia: C2H2
Kūlana Kino: Ma ka wela a me ke kaomi maʻamau (STP), he kinoea ka acetylene. Mālama ʻia ia i hoʻoheheʻe ʻia i loko o kahi solvent e like me ka acetone i loko o nā cylinders kiʻekiʻe a i hana ʻia ma ka pūnaewele no ka hoʻohana koke ʻana.
Kaumaha Molekala: Ma kahi o 26.04 g/mol.
Lae paila: -83.8°C (-120.84°F) ma 1 lewa.
Lae hehee: -81.8°C (-115.24°F).
Māmā: Ma kahi o 1.17 kg/m³ ma STP, ʻoi aku ka māmā ma mua o ka ea.
ʻO ke kaomi mahu: Kiʻekiʻe loa, pono e noʻonoʻo pono i ka mālama ʻana.
Solubility: Hiki ke hoʻoheheʻe ʻia i loko o ka wai akā hiki ke hoʻoheheʻe ʻia i nā mea hoʻoheheʻe organik e like me ka acetone a me ka ethanol.
ʻAi ahi a me ka hana hou ʻana: Hiki ke ʻā a pahū ka Acetylene i ka hui ʻana me ka ea ma kekahi mau ʻāpana (ma waena o 2.5% a me 82%). Hoʻoikaika ikaika ʻo ia me ke keleawe, ke kālā, ka mercury, a me kā lākou mau mea hoʻohui, e hana ana i nā mea pahū; no laila, pono e hoʻokuʻu ʻia nā mea hana acetylene i kēia mau mea.
Nā hoʻohana o ka acetylene:
Welding and Cutting: ʻO ka Acetylene ke kinoea wahie i koho ʻia i nā lama oxy-acetylene ma muli o kona puka wela kiʻekiʻe, kūpono ia no ka ʻoki metala, wili, a me ka brazing.
ʻO ka Synthesis Chemical: Hoʻohana ʻia ma ke ʻano he mea maka i ka hana ʻana i nā kinikona like ʻole, me ka vinyl acetate, acetic acid, a me ka chloroprene.
Ke kukui: Ma ka mōʻaukala, ua hoʻohana ʻia i nā kukui carbide no ka hoʻomālamalama.
Heat Treatment: Hāʻawi i ka wela wela kiʻekiʻe no ka annealing, paʻakikī, a me nā kaʻina hana wela ʻē aʻe.
Nā manaʻo palekana:
ʻO ke ahi nui a me ka pōʻino: Pono e mālama pono i ka mālama ʻana a me ka mālama ʻana i nā protocols e pale ai i ka ʻā.
ʻAiʻona: ʻOiai ʻaʻole ʻona nui ka acetylene ponoʻī, hiki i kāna mau mea puhi ahi ke lilo i mea pōʻino, ʻoi aku ka maikaʻi ma nā wahi ʻino.
Nā Lako Copper-Free: Pono e hana ʻia nā mea hana a pau i hoʻohana ʻia me ka acetylene mai nā mea hana ʻole me ia, e like me ke kila kuhili ʻole a i ʻole ke keleawe ʻole i ʻoi aku ka nui o ke keleawe.
I ka ʻimi ʻana i ka mea hoʻolako acetylene, e ʻimi i nā mea hoʻolako kinoea kaulana a i ʻole nā mea hoʻolaha kinoea kūikawā i ʻike maikaʻi i ka mālama pono ʻana, mālama ʻana, a me ka lawe ʻana i kēia kinoea reactive loa. Pono lākou e hāʻawi i nā cylinders i hoʻopiha ʻia me ka acetylene dissolved a i ʻole e hāʻawi i nā ʻōnaehana hana acetylene ma ka pūnaewele, e hōʻoia ana i ka hoʻokō ʻana i nā lula palekana a me nā hana maikaʻi loa o ka ʻoihana.
He hui kūikawā ʻo Shanghai Zhongwei Chemical Co., Ltd. i ka noiʻi, hana, a kūʻai aku i nā kinoea kūikawā a me nā isotopes paʻa. Loaʻa iā mākou kā mākou hui noiʻi a me ka hale hana, a me kā mākou hale hana ponoʻī. No nā makahiki he nui, ua kūpaʻa mākou i ka hāʻawi ʻana i nā huahana kiʻekiʻe a me nā lawelawe i nā mea kūʻai aku ma nā kula e like me ka hana semiconductor, noiʻi lāʻau hou a me ka hoʻomohala ʻana, aerospace, a me nā ʻoihana ikehu lā. Ua hoʻokumu mākou i nā pilina pili pili me nā ʻoihana kaulana a me nā ʻoihana ʻē aʻe, a komo ikaika i nā papahana hui honua. Ua lawe ʻia kā mākou huahana a me kā mākou ʻenehana i nā ʻāpana like ʻole o ka honua a ua lanakila nui ka mākeke honua.
Inā makemake ʻoe i kēlā mau huahana, e ʻoluʻolu e hoʻokaʻaʻike mai iā mākou!
