Sodium persulfate

Sodium persulfateʻO ka sodium persulfate ka mea i ʻike ʻia he hui inorganic, ʻo ke ʻano kemika Na2S2O8, he pauka crystalline keʻokeʻo, hiki ke hoʻoheheʻe ʻia i ka wai, hiki ʻole ke hoʻoheheʻe ʻia i ka ethanol, hoʻohana nui ʻia e like me ka bleach, oxidant, emulsion polymerization accelerator.

Nā waiwai:ʻO ke aniani keʻokeʻo a i ʻole ka pauka crystalline. ʻAʻohe ʻala. ʻono ʻole. ʻO ke kumu molekala Na2S2O8, kaumaha molekala 238.13. Hiki ke hoʻoheheʻe ʻia ma ka lumi wela, a hiki ke hoʻopau koke ʻia e ka hoʻomehana ʻana a i ʻole ka ethanol, a laila hoʻokuʻu ʻia ka oxygen a hoʻokumu ʻia ka sodium pyrosulfate. ʻO ka wai a me ka platinum ʻeleʻele, ke kālā, ke alakaʻi, ka hao, ke keleawe, ka magnesium, nickel, manganese a me nā ion metala ʻē aʻe a i ʻole kā lākou mau mea e hiki ai ke hoʻoikaika i ka decomposition, ka wela kiʻekiʻe (e pili ana i 200 ℃) decomposition wikiwiki, hoʻokuʻu i ka hydrogen peroxide. Hiki ke hoʻoheheʻe ʻia i ka wai (70.4 ma 20 ℃). He oxidizing loa ia. ʻO ka huhū ikaika i kaʻili, ka pilina lōʻihi me kaʻili, hiki ke hoʻoulu i nā meaʻaeʻa, pono e hoʻolohe i ka hana. Iole transoral LD50895mg/kg. E mālama pono. Hoʻokumu ke keʻena hana i ka sodium persulfate ma ka hoʻomehana ʻana i kahi hopena o ka ammonium persulfate me ka soda caustic a i ʻole ka sodium carbonate e wehe i ka amonia a me ke kalapona kalapona.

ʻO ka mea hoʻoheheʻe ikaika:ʻO ka sodium persulfate ka ikaika o ka oxidation, hiki ke hoʻohana ʻia ma ke ʻano he oxidizing agent, hiki ke oxidize Cr3+, Mn2+, etc. Hiki ke hoʻohana ʻia e like me ka bleaching agent, ka mea hoʻomaʻamaʻa ʻili metala a me ka reagent kemika e kāna waiwai oxidation. ʻO nā mea lāʻau lapaʻau; ʻO nā mea hoʻolalelale a me nā mea hoʻomaka no ka pākaukau a me ka emulsion polymerization reactions.

Palapala noi：Loaʻa ka sodium persulfate i ka hoʻohana nui ʻana ma ke ʻano he bleach, oxidant, a me ka emulsion polymerization accelerator. ʻO kona hiki ke wehe i nā ʻili a me nā lole keʻokeʻo ua loaʻa iā ia kahi inoa kaulana ma ke ʻano he mea hoʻomaʻemaʻe. Inā paha he ʻeleʻele waina paʻakikī ma kāu pālule punahele a i ʻole nā ​​​​lino ʻulaʻula, hiki i ka sodium persulfate ke hoʻoponopono maʻalahi i kēia mau pilikia.

Eia kekahi, hōʻike ka sodium persulfate i nā waiwai oxidizing potent. ʻO kēia ka mea kūpono no ke kōkua ʻana i nā hopena kemika e pono ai ka wehe ʻana i nā electrons. I loko o nā ʻoihana e hilinaʻi nui nei i nā kaʻina hana oxidation, e like me ka hana ʻana i nā lāʻau lapaʻau a me nā kala, ʻo ka sodium persulfate ka mea waiwai nui.

Eia kekahi, lawelawe pū kēia pūhui ma ke ʻano he emulsion polymerization promoter. No ka poʻe ʻike ʻole i ka huaʻōlelo, pili ka polymerization emulsion i ke kaʻina hana o ka synthesizing polymers i loko o kahi ʻano wai. Hana ʻo Sodium persulfate ma ke ʻano he catalyst, kōkua i ka hoʻokumu ʻana i kēia mau polymers. ʻO nā ʻoihana e hoʻohana ana i ka polymerization emulsion, e like me nā adhesives a me nā uhi, ke hilinaʻi nui nei i ka sodium persulfate no kona pono i ka loaʻa ʻana o nā hopena i makemake ʻia.

ʻO ke ʻano multifaceted o ka sodium persulfate ka mea i hoʻokaʻawale iā ia mai nā pūhui ʻē aʻe. ʻO kona hiki ke hana ma ke ʻano he bleaching agent a me ka oxidant e lilo ia i koho maikaʻi no nā ʻano ʻoihana ākea. Hoʻohui ʻia, ʻo kāna emulsion polymerization e hoʻolaha ana i nā waiwai e hoʻonui i ka laulā o ka noi.

Ma waho aʻe o kāna mau hoʻohana like ʻole, hoʻonani ka sodium persulfate i kekahi mau hiʻohiʻona ʻokoʻa. Hoʻonui ka hoʻoheheʻe wai i kona pono ma ke ʻano he bleach a me ka oxidant, e ʻae iā ia e hoʻoheheʻe a launa pū me nā mea ʻē aʻe. Ma ka ʻaoʻao ʻē aʻe, ʻo kona insolubility i ka ethanol e pale iā ia mai ka hoʻopili ʻana i nā kaʻina hana e hilinaʻi nei i ka ethanol ma ke ʻano he mea hoʻoheheʻe.

No ka hoʻohana pono ʻana i ka sodium persulfate, pono e noʻonoʻo i kekahi mau mea. Pono ka mālama pono ʻana a me ka mālama ʻana i nā alakaʻi palekana ma muli o kona ʻano pōʻino. Eia kekahi, he mea koʻikoʻi ke ʻano kūpono i ka hoʻokomo ʻana i ka sodium persulfate i kekahi kaʻina hana, ʻo ia ka bleaching, oxidation, a i ʻole emulsion polymerization.

Nā hana mālama:hana paʻa, hoʻoikaika i ka ea. Pono nā mea hana e hoʻomaʻamaʻa kūikawā a mālama pono i nā kaʻina hana. Manaʻo ʻia e hoʻohana nā mea hoʻohana i kahi kānana lako ea uila ʻano uhi poʻo i ka respirator pale lepo, nā lole pale polyethylene, a me nā mīkina lima. E mālama i ke ahi a me ka wela. ʻAʻole puhi paka ma kahi hana. E pale i ka hana ʻana i ka lepo. Hōʻalo i ka hoʻopili ʻana me nā mea hoʻohaʻahaʻa, nā pauka metala ikaika, nā alkali, nā waiʻona. I ka lawelawe ʻana, pono e hana ʻia ka hoʻouka māmā ʻana a me ka wehe ʻana i mea e pale ai i ka pōʻino o ka pahu a me nā ipu. Mai haʻalulu, hopena a me ka hakakā. Hoʻolako ʻia me nā ʻano like ʻole a me ka nui o nā lako ahi a me nā lako lapaʻau ulia pōpilikia. Loaʻa paha nā koena pōʻino i nā ipu ʻole.

Nā mālama mālama:E kūʻai i loko o kahi hale kūʻai maloʻo, maloʻo a maikaʻi. E mālama i ke ahi a me ka wela. ʻAʻole ʻoi aku ka mahana o ka waihona ma mua o 30 ℃, a ʻaʻole ʻoi aku ka haʻahaʻa haʻahaʻa ma mua o 80%. Hoʻopaʻa ʻia ka pūʻolo. Pono e hoʻokaʻawale ʻia mai nā mea hoʻohaʻahaʻa, nā pauka metala ikaika, nā alkali, nā ʻona, a me nā mea ʻē aʻe, a ʻaʻole pono e hui pū ʻia. Pono e hoʻolako ʻia nā wahi waiho ʻana me nā mea kūpono e loaʻa ai nā leaka.

I ka hopena, noho mau ka sodium persulfate i mea maʻalahi a pono ʻole. ʻO kona pono ma ke ʻano he bleach, oxidant, a me ka emulsion polymerization promoter e koi nui iā ia. Me kāna ʻano kemika ʻo Na2S2O8, ke hoʻomau nei kēia pauka crystalline keʻokeʻo i ka hana koʻikoʻi ma waena o nā ʻoihana like ʻole. E like me nā mea hoʻohui kemika, pono e mālama i ka sodium persulfate me ka mālama a e noʻonoʻo i ke ʻano kūpono. No laila, i ka manawa aʻe e ʻike ai ʻoe iā ʻoe iho i kahi bleach hilinaʻi a i ʻole oxidant, e noʻonoʻo e kiʻi i ka sodium persulfate, ka pūhui hale mana ʻaʻole e hāʻawi i nā hopena kūʻokoʻa.
