NUI HUA

Hiki ke hoʻoheheʻe ʻia ke kinoea fluoride hydrogen i ka wai, a ua kapa ʻia kona ʻano waiʻakika hydrofluoric.ʻO ka huahana he 35% -50% aqueous solution o ka hydrogen fluoride gas, hiki ke kiʻekiʻe kiʻekiʻe ke piʻi i ka 75%, a ʻo ia ka wai ulaula ʻole a hoʻomaʻamaʻa ʻia.ʻAʻala ʻala, lele, uahi keʻokeʻo i ka lewa.He ʻakika inorganic ikaika kona, ʻino loa, a hiki ke hoʻopau i ke aniani a me nā silicates e hana ai i ke kinoea silicon tetrafluoride.Hiki iā ia ke launa pū me nā metala, metala oxides a me nā hydroxides e hana i nā paʻakai like ʻole, akā ʻaʻole ikaika ka hopena e like me ka waika hydrochloric.ʻAʻole hana pū ke gula, platinum, ke kēpau, paraffin a me kekahi mau plastics, no laila hiki ke hana ʻia nā ipu.He mea maʻalahi ke kinoea hydrogen fluoride e polymerize, hana (HF) 2 (HF) 3·· ʻano molekole iso-chain, ma ke ʻano wai, piʻi ka degere o ka polymerization.E mālama i loko o nā pahu i hana ʻia me ke kēpau, ka wax a i ʻole ka plastic.He mea ʻawaʻawa loa ia a me ka ulcerates ma ka pili ʻana i ka ʻili.

PAPA HANA

ʻO ka hana graphite

ʻO ka waika Hydrofluoric he waikawa ikaika hiki ke hana me nā mea haumia ʻē aʻe i loko o ka graphite, a he kūpaʻa maikaʻi ka graphite, ʻoi aku ka hiki ke kū i ka waika hydrofluoric, kahi e hoʻoholo ai e hiki ke hoʻomaʻemaʻe ʻia ka graphite me ka waika hydrofluoric.ʻO ke kaʻina hana nui o ka hydrofluoric acid ka hui ʻana o ka graphite a me ka waika hydrofluoric, a me ka hopena o ka waika hydrofluoric a me nā haumia no kekahi manawa e hana i nā mea hiki ke hoʻoheheʻe ʻia a i ʻole nā ​​​​mea hoʻoheheʻe, ma hope o ka holoi ʻana e wehe i nā haumia, dehydration a me ka maloʻo e loaʻa ai ka graphite maʻemaʻe.

Laaa honua Laaa

ʻO ka hoʻomākaukau ʻana i ka anhydrous rare earth fluoride ma muli o ka ua o ka hydrated rare earth fluoride mai ka wai wai, a laila dehydration, a i ʻole fluorination pololei o nā oxides honua me nā mea hana fluorinating.He liʻiliʻi loa ka solubility o ka fluoride honua, a hiki i ka hoʻohana ʻana i ka waika hydrofluoric ke hoʻoheheʻe ia mai ka waika hydrochloric, sulfuric acid a i ʻole ka waika nitric o ka honua laʻa (ʻo ka precipitate ma ke ʻano o ka fluoride hydrated).

Metala ili lapaʻau

Wehe i nā mea haumia i loko o ka oxygen ma luna o ka waika Hydrofluoric he ʻakika nāwaliwali, e like me ka ikaika me ka waikawa formic.ʻO ka manaʻo nui o ka waika hydrofluoric hiki ke kūʻai ʻia he 30% a 50%.ʻO nā hiʻohiʻona nui o ka hydrofluoric acid rust removal penei: (1) Hiki ke hoʻoheheʻe i nā pūhui i loko o ka silicon, aluminika, chromium a me nā mea metala ʻē aʻe i loaʻa ka solubility maikaʻi, hoʻohana mau ʻia e etch castings, stainless steel a me nā mea hana ʻē aʻe.(2) No nā mea hana kila a me ka hao, hiki ke hoʻohana ʻia ka waika hydrofluoric haʻahaʻa no ka wehe ʻana i ka ʻōpala.Aqueous solution of hydrofluoric acid with a concentration of 70% has passivation effect on steel (3) Hydrofluoric acid with a concentration of 10% has a weak corrosion on magnesium and its alloys, no laila ua hoʻohana pinepine ia no ka etching o ka magnesium workpieces.(4) ʻAʻole i ʻino ʻia ke kēpau e ka waika hydrofluoric;Loaʻa i ka Nickel ke kū'ē ikaika i nā waika hydrofluoric me ka nui o ka nui ma mua o 60%.ʻO ka waiʻona Hydrofluoric he meaʻawaʻawa loa, a me ka maʻalahi, ke hoʻohanaʻia e pale i ka pilina kanaka me ka waiʻona hydrofluoric a me ke kinoea hydrogen fluoride, ua hoʻopaʻa maikaʻiʻia ka pahu etching a he maikaʻi hoʻi ka ventila, hiki ke hoʻokuʻuʻia ka waiʻawaʻawa fluorinated ma hope o ka mālamaʻana.

ʻO ke one quartz pickling

ʻOi aku ka maikaʻi o ka hana ʻana me ka waika hydrofluoric, akā koi ʻia ka ʻike kiʻekiʻe.Ke kaʻana like me ka sodium dithionite, hiki ke hoʻohana ʻia nā haʻahaʻa haʻahaʻa o ka waika hydrofluoric.Hoʻohui ʻia kekahi ʻano o ka waika hydrochloric a me ka waika hydrofluoric i loko o ka slurry one quartz i ka manawa like e like me ka nui;Hiki ke mālama ʻia me ka waika hydrochloric solution ma mua, holoi ʻia a laila mālama ʻia me ka waika hydrofluoric, mālama ʻia i ke kiʻekiʻe wela no 2-3 mau hola, a laila kānana a hoʻomaʻemaʻe ʻia Hiki ke wehe maikaʻi ʻia nā haumia a me nā oxides ma ka ʻili o ke one quartz, a hiki ke hoʻonui i ka maʻemaʻe a me ka maikaʻi o ke one quartz.

FOCS Fiber corrosion

Ua hoʻomohala ʻia ka waika hydrofluoric hoʻopiha i ka corrosion o ka fiber crystal photonic (PCF).Ua hoʻopiha ʻia ka ʻakika Hydrofluoric i loko o ka lua ea o ka fiber crystal photonic i huki ʻia.Ma ka hoʻololi ʻana i kāna ʻāpana ʻāpana keʻa, ua kūkulu ʻia ka fiber crystal photonic me kahi ʻano kikoʻī e hoʻololi i kona conductivity māmā.Hōʻike nā hopena i ka emi ʻana o ka nalowale o ka leakage a me ka hoʻopuehu ʻana me ke degere corrosion o ka puka ea o ka fiber crystal photonic, ke piʻi aʻe nei ka coefficient nonlinear, ʻoi aku ka emi ʻana o ka helu refractive kūpono o ke ʻano kumu a me ka helu hoʻohālikelike like o ka pale ʻana e hoʻemi like. a hoʻololi pū ka puʻu ʻana o ka hui.

ʻO ka hoʻoheheʻe ʻana o ka pale TPT-LCD

Ma lalo o ka pale ʻana o ka photoresist a me ke kāpili palena, hoʻoponopono ʻia ka neʻe ʻana o ka waika hydrofluoric, kahi nui o ka waikawa nitric, hoʻohui ʻia ka sulfuric acid a me ka waikawa hydrochloric, a ua hoʻohui ʻia nā kūlana kōkua ultrasonic, ua maopopo ka hoʻomaikaʻi ʻana o ka etching rate.Hoʻemi maikaʻi ʻia ka roughness o ka ʻili e ka hoʻomaʻemaʻe ʻana i nā kaʻina hana hoʻomaʻemaʻe, a hoʻemi ʻia ka ua o nā mea hoʻopili keʻokeʻo.E hoʻoholo i ka pilikia o ka ʻili ʻeleʻele a me ka hoʻopili ʻana o ka ʻili keʻokeʻo.
