Sodium Formate

Sodium formateHe pauka keʻokeʻo a he crystalline paha, me kahi ʻala waikawa formic iki. Hoʻoheheʻe ʻia i ka wai a me ka glycerin, hoʻoheheʻe iki ʻia i ka ethanol, hoʻoheheʻe ʻole ʻia i ka ether. ʻAwaʻawa. Hiki ke hoʻohana ʻia i ka hana ʻana o ka waikawa formic, ka waikawa oxalic, ka formamide a me ka pauka ʻinikua, ka ʻoihana ʻili, ka waikawa camouflage chrome tannery, hoʻohana ʻia i nā catalysts.

Nā Waiwai:He pauka keʻokeʻo kristal ka sodium formate, hygroscopic iki, ʻala waikawa formic iki, hoʻoheheʻe ʻia i ka wai, hoʻoheheʻe iki ʻia i ka ethanol, hoʻoheheʻe ʻole ʻia i ka ether, ke kaumaha kikoʻī 1.919, kiko heheʻe 253 ℃, delix i ka lewa, kūpaʻa kemika.

Nā noi nui:

Hoʻohana ʻia i loko o ka ʻoihana ʻili, ʻo nā hoʻohana nui penei:

(1) Hoʻohana nui ʻia i ka hana ʻana o ka waikawa formic, ka waikawa oxalic a me ka pauka ʻinikua, akā hoʻohana pū ʻia i ka hana ʻana o ka dimethylformamide, a pēlā aku. Hoʻohana pū ʻia i ka lāʻau lapaʻau, ka paʻi ʻana a me ka ʻoihana hoʻoluʻu.

(2) nā reagents, nā disinfectants a me ka mordant no ka hoʻoholo ʻana o ka phosphorus a me ka arsenic;

(3) Hoʻohana ʻia ma ke ʻano he mea mālama. no ka uhi ʻana o ka resin alkyd, plasticizer, ikaika;

(4) Hoʻohana ʻia e like me nā mea pahū, nā mea kūpaʻa waikawa, ka ʻaila lubricating mokulele, nā mea hoʻohui pipili.

ʻO ka sodium formate a meCʻālika formate:

ʻO ka sodium formate a me ka calcium formate ʻelua mau paʻakai metala maʻamau o ka formate. Ua ʻike ʻia hoʻi ʻo Sodium formate ʻo ia ka sodium formate. Aia ʻelua mau ʻano molekala o nā hui sodium formate ma ke ʻano:

① He pauka keʻokeʻo kristal ka sodium formate anhydrous, hygroscopic iki, ʻawahia. ʻO ka nui o ka density he 1.92 (20 ℃) ​​a ʻo ke kiko heheʻe he 253 ℃. Hoʻoheheʻe ʻia i ka wai, hoʻoheheʻe iki ʻia i ka ethanol, hoʻoheheʻe ʻole ʻia i ka ether.

② He kristal kala ʻole ka sodium dihydrate. He ʻala waikawa formic iki, ʻawahia. Hoʻoheheʻe ʻia i ka wai a me ka glycerin, hoʻoheheʻe iki ʻia i ka ethanol. I ka wela nui, wāwahi ia i loko o ka hydrogen a me ka sodium oxalate, a ma hope i loko o ka sodium carbonate. Hana ʻia ia e ka launa pū ʻana o ka waikawa formic me ka sodium hydroxide.

ʻO nā hoʻohana nui o ka sodium formate penei:

Hiki ke hoʻohana ʻia ka sodium formate ma ke ʻano he reagent loiloi kemika, hoʻohana ʻia no ka hoʻoholo ʻana i ka ʻike o ka arsenic a me ka phosphorus, akā hoʻohana ʻia hoʻi ma ke ʻano he disinfectant, mordant, a pēlā aku. I ka ʻoihana, hoʻohana ʻia ka pauka sodium formate e pani i ka waikawa formic e hoʻomaikaʻi i ka hana o ka ʻōnaehana limestone FGD.

ʻAno hoʻomākaukau no ka sodium formate:Hoʻohana ʻia ka sodium bicarbonate i loko o ka hale hana e hana me ka waikawa formic e mālama i ka hopena alkaline, wehe i ka Fe3+, kānana, hoʻohui i ka waikawa formic i loko o ka filtrate, hoʻolilo i ka hopena i waikawa nāwaliwali, evaporate a crystallize e loaʻa ai ka sodium formate maka.

ʻO ka calcium formate kahi pauka crystalline keʻokeʻo manuahi me nā hopena anti-mold, anti-corrosion a me antibacterial. He mea hoʻohui hānai waikawa organik. ʻO ka nui o 99%, 69% formic acid, 31% calcium, haʻahaʻa ka nui o ka wai. He kiʻekiʻe ke kiko heheʻe o kēia huahana a ʻaʻole maʻalahi e luku ʻia i loko o nā mea granular. E hoʻohui i ka 0.9% ~ 1.5% i ka hānai. Hoʻokaʻawale kēia huahana i ka waikawa formic i loko o ka ʻōpū, hoʻemi i ka pH o ka ʻōpū, mālama i ka acidity o ke ala ʻai, a pale i ka ulu ʻana o nā bacteria pathogenic, no laila e kāohi ana a pale i ka hanana ʻana o ka maʻi diarrhea e pili ana i ka maʻi bacteria. Hiki i ka trace formic acid ke hoʻoulu i ka hana o ka pepsinogen a hoʻomaikaʻi i ka omo ʻana o nā mea hana i ka hānai. Chelate me nā minelala i ka hānai e hoʻolaha i ka ʻai ʻana a me ka omo ʻana o nā minelala; Hiki ke hoʻohana ʻia ma ke ʻano he mea hoʻohui calcium. Hiki iā ia ke pale i ka maʻi diarrhea a hoʻomaikaʻi i ka helu ola o nā puaʻa. Paipai i ka hoʻololi ʻana o ka hānai a hoʻonui i ka loaʻa o kēlā me kēia lā.

Ka hoʻopili ʻana, ka mālama ʻana a me ka halihali ʻana:Hoʻopaʻa ʻia ka ʻōpala i loko o nā pahu hao i uhi ʻia me ka ʻili plastik, mālama ʻia i kahi maloʻo, ea maikaʻi, pale i ka lā pololei, mai nā kumu wela, ka waikawa, ka wai, ka ea pulu.

I ka hopena, he hui koʻikoʻi ka sodium formate e pāʻani ana i kahi hana koʻikoʻi i nā ʻoihana like ʻole. Hoʻohana ʻia ia i ka hana ʻana o nā kemika pono he nui, me ka waikawa formic, ka waikawa oxalic, ka formamide, a me ka dimethylformamide, a hoʻohana ʻia hoʻi i ka ʻoihana ʻili. ʻO kona ʻano aloha kaiapuni, ka lōʻihi, a me ka versatility e lilo ia i koho kūpono i nā noi he nui. No laila, he hui ia e pono ke ʻimi ʻia e nā ʻoihana e hiki ke pōmaikaʻi nui mai kona mau waiwai.
