Sodium acetate mea hana pehea e koho, sodium acetate discoloration hiki ke hoʻomau i ka hoʻohana?
ʻO nā mea hana sodium acetate pehea e koho ai, hiki ke hoʻomau i ka hoʻohana ʻana o ka sodium acetate discoloration?,
Sodium Acetate, mea hana sodium acetate, kumu hoʻohālike sodium acetate, mea hoʻolako sodium acetate,
Nā waiwai physicochemical:
1. ʻAʻohe kala a ʻaʻole hoʻi ka ʻākala monoclinic prismatic crystal a i ʻole ka pauka crystalline keʻokeʻo, ʻala ʻole a ʻala iki paha, ʻawaʻawa iki, maʻalahi ke anā i ka ea maloʻo a pulu.
2. ʻO ka wai hoʻoheheʻe (46.5g / 100mL, 20 ℃, pH o 0.1mol / L aqueous solution he 8.87), acetone, etc., hiki ke hoʻoheheʻe ʻia i ka ethanol, akā ʻaʻole hiki ke hoʻoheheʻe ʻia i ka ether.
3. Kekahi hehee (℃): 324
Storge
1. E mālama i kahi i sila a maloʻo.
2. Hoʻopili ʻia me ka ʻeke ʻeke i hoʻopaʻa ʻia, ʻeke i ulana ʻia a i ʻole ʻeke pū e like me ke kapa waho. He deliquescent ka sodium acetate, no laila pono e pale ʻia mai ka makū i ka wā o ka mālama ʻana a me ka lawe ʻana. ʻAʻole loa e hoʻopili ʻia me ke kinoea corrosive, pale i ka ʻike ʻana i ka lā a me ka ua, a lawe pū me ka uhi ua.
Hoʻohana
1. Ka hoʻoholo ʻana o ke kēpau, zinc, aluminika, hao, cobalt, antimony, nickel a me ka tin. Mea hoʻopaʻa paʻakikī. He mea kōkua, hoʻopaʻa, desiccant, mordant no ka acetylation.
2. Hoʻohana ʻia no ka hoʻoholo ʻana i ke kēpau, zinc, aluminika, hao, cobalt, antimony, nickel, a me ka tin. Hoʻohana ʻia ma ke ʻano he esterification agent i ka organik synthesis a me nā ʻano he nui e like me nā lāʻau lapaʻau kiʻi, nā lāʻau lapaʻau, ka paʻi ʻana a me ka hoʻoheheʻe ʻana i nā mordants, buffers, chemical reagents, meat preservatives, pigments, tanning, etc.
3. Hoʻohanaʻia ma keʻano he pale, meaʻono, meaʻono a me ka pH regulator. Ma ke ʻano he pale o ka mea ʻono, hiki ke hoʻohana ʻia ka 0.1% -0.3% e hoʻopau i ka ʻala ʻino a pale i ka discoloration e hoʻomaikaʻi i ka ʻono. Loaʻa iā ia kahi hopena anti-mold, e like me ka hoʻohana ʻana i ka 0.1% -0.3% i nā huahana surimi a me ka berena. Hiki ke hoʻohana ʻia e like me ka mea ʻawaʻawa no ka hoʻomoʻa ʻana i ka ʻuala, sauerkraut, mayonnaise, iʻa keke, sausage, berena, sticky keke, etc. Hoʻohui ʻia me ka methyl cellulose, phosphate, etc. keke, etc.
4. Hoʻohana ʻia ma ke ʻano he mea pale no ka sulfur-regulated chloroprene rubber coking. ʻO ka maʻamau he 0.5 mau ʻāpana ma ka nui. Hiki ke hoʻohana ʻia ma ke ʻano he crosslinking agent no ke kāpili holoholona.
5. Hiki ke hoʻohana ʻia kēia huahana e hoʻohui i ka tin electroplating alkaline, akā ʻaʻohe hopena i ʻike ʻia i ke kaʻina hana a me ka electroplating, a ʻaʻole ia he mea pono. Hoʻohana pinepine ʻia ʻo Sodium acetate ma ke ʻano he pale, e like me ka plating zinc acid, alkaline tin plating a me ka electroless nickel plating.

No ka poʻe i kamaʻāina i ka sodium acetate, hoʻohana ʻia ka sodium acetate, ka mea i kapa ʻia ʻo sodium acetate, i nā ʻano hana like ʻole, me nā studio kiʻi kiʻi, ka decontamination kīhini, ka mālama ʻana i ka wai, a me nā huahana meaʻai.
Nui nā mea hana meaʻai e dehydrogenate sodium acetate i mea e mālama ai i ka meaʻai. No laila, kapa ʻia ka sodium dehydrogenate i ka ʻoihana meaʻai. He mea nui ia i ka hoʻomohala ʻana i ka ʻoihana meaʻai.
ʻO ka sodium dehydroacetate kekahi o nā mea mālama i ʻike ʻia i ka ʻoihana. Loaʻa iā ia nā pōmaikaʻi ma ka ʻoihana meaʻai:
1. Hiki iā ia ke pale i nā fungi
2. ʻAʻole ia e wāwahi i ka wā e hana ai i ka meaʻai
3. ʻAʻole ia e evaporate i ka pili ʻana me ka wai
4. Paʻa paʻa, ke hiki i ka hoʻomehana ke hōʻoia ʻaʻole e luku i ka meaʻai.
He nui nā mea hana e manaʻo i ka sodium acetate ma hope o ke kūʻai ʻana i ka kala sodium acetate ʻaʻole pololei, ʻo ia no ka mea hiki ke hoʻoheheʻe ʻia ka sodium acetate i ka wai, i ka hālāwai ʻana me nā kala ʻē aʻe o ka metala, e ʻike ʻia nā kala ʻē aʻe, ʻike iki ke kala. e like me ka sodium acetate, inā hoʻohana ʻia e hana i nā hana koʻikoʻi, ʻōlelo kēia kūlana e hoʻohana pono mākou i ka makaʻala!
Eia kekahi, pono e mālama pono ʻia ka sodium acetate a mākou i kūʻai ai mai ka hale hana, i pale ʻia ai ka discoloration.
I ka wā e pili ana i ka mālama ʻana i ka sodium acetate, ke ʻōlelo nei au i nā ala mālama kūpono a pololei:
1. Hoʻomanaʻo ka sodium acetate ʻaʻole e hoʻopā i ka wai, no laila e hoʻopaʻa ʻia mākou a maloʻo ma lalo o ke ʻano o ka mālama ʻana.
2 pono e hoʻolohe iā ia i ka lawe ʻana e hana i nā ʻano moisture-proof, makaʻu nui ka sodium acetate i ke kai, akā ʻaʻole hiki ke ʻike ʻia i ka lā a me ka ua, i ka lawe ʻana e hāʻawi i nā hana pale maikaʻi, i mea e hōʻoia ai i ka ka maemae o ka sodium acetate.
3. I ke kaʻina o kā mākou lawe ʻana, pono mākou e hoʻomanaʻo e nānā i ka mokuʻāina o ka paʻakai o ka sodium acetate i ka manawa. Inā mākou e nānā pono, hiki iā mākou ke pale aku i ka hopena o ke kūlana kūpaʻa o ka sodium acetate a hoʻolilo iā mākou i nā poho ma muli o ka ʻeke ʻeke ʻeke a lepo.
Ma ke koho ana omea hana sodium acetates, pono mākou e poni i ko mākou mau maka e ʻike i nā mea hana hilinaʻi, ua ʻike au i ka nui o nā mea hana e ʻike i ka koi o ka mea kūʻai aku no ka sodium acetate ma ke kumukūʻai, ʻaʻole ʻōlelo kēia ʻano mea hana iā ʻoe e koho.
Ke koho mākou i nā mea hana sodium acetate, pono mākou e hoʻomanaʻo e koho i nā mea hana me ka maikaʻi o ka huahana, ka maikaʻi maikaʻi, ka inoa maikaʻi a me ke kumukūʻai e like me kā mākou mau manaʻo. ʻO ka mea maʻamau, ʻo kēia ʻano mea hana e lilo i mea hana a me ke kūʻai aku, a me ka pale ʻana ma hope o ke kūʻai aku, ʻaʻole ia e ʻae i nā mea kūʻai aku e pohō.
