Nā mea hoʻoheheʻe kemika–Methylene Chloride i hana ʻia ma Kina

Hoʻolauna Huahana

ʻO Rich Chemical kahi mea hoʻolako ʻoihana Kina i ka dichloromethane papa hana ʻenehana i hana ʻia ma Kina, kahi i hana i nā kemika kūlohelohe no 10 mau makahiki.Ke hāʻawi nei i ka hōʻailona manuahi, hoʻokipa maikaʻi mākou iā ʻoe e kūʻai i nā kemika kiʻekiʻe CAS No. me ka maʻemaʻe kiʻekiʻe a me ke kumu kūʻai haʻahaʻa me mākou.

kikoʻī huahana
Huina molekala: CH2CL2
Kaumaha molekula: 84.93
Nā waiwai kino a me nā kemika: ʻaʻohe waihoʻoluʻu a ʻaʻole i like me ka ʻala o ka ether a me ka ʻono.
Māmā pili: D4201.326Kg/L.
wahi hoʻolapalapa: 40.4 DEG C.
wahi hoohehee: -96.7 degere, ka lae wela o ka 615 DEG C. Hiki ke hooheheeia i ka wai, hiki ke hooheheeia i ka ethanol, ethyl ether, toxic, narcotic stimulation.ʻO ka dichloromethane a me ka hopena hydrolysis wai, dichloromethane i loaʻa ka stabilizer pāʻoihana, e pale i ka hydrolysis.ʻO ka dichloromethane a me ka oxygen kiʻekiʻe e hoʻohua i ka hui pahū, akā ʻaʻole hiki ke puhi ʻia, hoʻohana maʻamau ʻia i ka ʻoihana haʻahaʻa haʻahaʻa, ka mea hoʻoheheʻe ʻole a me ka wahi paila haʻahaʻa.

Ke kumu
No ka mea hoʻoheheʻe ʻole: hoʻomaʻemaʻe metala, wehe i ka pena, mea hoʻoheheʻe metala, ʻekolu mea hoʻoheheʻe cellulose acetate;kiʻiʻoniʻoni, aerosol, antibiotics a me nā huaora i ka hana ʻana o ka solvent;mea ho'ohuhū no ka hana 'ana i nā plastic 'enekinia;nā huahana pale ahi;hoʻohana ʻia e hoʻololi i ka hoʻohana ʻana o F11 a me F12 no ka synthesis o nā huahana;huahana kemika maikaʻi.

Packaging, mālama a me ka lawe ʻana
ʻO ke kila kila, ka pahu kila ʻeleʻele a i ʻole ka pahu i hoʻopaʻa ʻia i ka pahu pahu hoʻopiha piha o ka dichloromethane, ka 80%, hiki ke hāʻawi i ka pale nitrogen no nā mea hoʻohana me nā koi kūikawā.Pono e mālama ʻia ka waihona ma kahi maloʻo a maloʻo, pono e hoʻokaʻawale ʻia ka hale kūʻai e pale aku i ka hoʻopili ʻana me nā kiʻekiʻe kiʻekiʻe o ka oxygen a i ʻole oxides, e pale i ka hoʻopili ʻana me ka wai i mea e pale ai i ka hydrolysis.E hoʻokō ka lawe ʻana i nā ʻōlelo a ka People's Republic of China e pili ana i ka lawe ʻana i nā kemika weliweli e nā alaloa a me nā alahao.

ʻO ke olakino a me ka palekana

ʻO Sichloromethane i ka palena pahū o ka lewa: 8.1 ~ 17.2%, pili i nā kemika combustible.ʻO ka noʻonoʻo kiʻekiʻe, ka lōʻihi o ka hoʻolaha ʻana i ka manawa maʻalahi ke kumu i ka dizziness, drowsiness, nausea, tinnitus a i ʻole numbness o nā lālā, neʻe i ka ea hou, ua hoʻihoʻi koke ʻia nā hōʻailona, ​​ʻaʻole ia e hōʻeha mau.ʻO ka pāpaʻi ʻana i nā maka e hōʻeha i ka ʻeha a me ka huhū, hiki i ka pili lōʻihi me ka ʻili ke hoʻoulu i ka dermatitis.
