Hiki ke hoʻoheheʻe ʻia ke kinoea hydrogen fluoride i ka wai, a ua kapa ʻia kona ʻano wai wai wai hydrofluoric acid.ʻO ka huahana maʻamau he 35% -50% hydrogen fluoride gas aqueous solution, hiki ke kiʻekiʻe kiʻekiʻe ke piʻi i 75%, no ka wai uahi i hoʻomaʻamaʻa ʻole ʻia.Honi ʻala, ʻala, uahi keʻokeʻo i ka lewa.He ʻakika inorganic ikaika loa ia a hiki ke hoʻoheheʻe 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 hiki ke hoʻohana i ke gula, ka platinum, ke kēpau, ka paraffin a me kekahi mau plastic, no laila hiki ke hana i nā ipu.Hoʻopili maʻalahi ke kinoea fluoride hydrogen e hana (HF) 2 (HF) 3· homochain mole, a 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 a hiki ke ʻeha i ka ʻili.

Hoohana Huahana
ʻO ke one quartz pickling
ʻOi aku ka maikaʻi inā mālama ʻia me ka waika hydrofluoric, akā koi ʻia nā ʻike kiʻekiʻe.Ke kaʻana like me ka sodium disulfite, 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 quartz mortar 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 ka wela kiʻekiʻe no 2-3 mau hola, a laila kānana a hoʻomaʻemaʻe ʻia, hiki ke hoʻopau pono i nā haumia a me nā oxides ma ka ʻili o ke one quartz a hoʻomaikaʻi. ka maʻemaʻe a me ka maikaʻi o ke one quartz.
Metala ili lapaʻau
Wehe i nā mea haumia i loko o ka oxygen, hydrofluoric acid he ʻakika nāwaliwali, like ka ikaika me ka formic acid.ʻO ka manaʻo nui o ka waika hydrofluoric hiki ke kūʻai ʻia he 30% a 50%.ʻO nā hiʻohiʻona nui o ka hoʻohemo ʻana i ka waika hydrofluoric e like me kēia:
(1) Hiki ke hoʻoheheʻe i nā pūhui silika, aluminika, chromium a me nā mea metala ʻē aʻe i loaʻa i ka solubility maikaʻi, hoʻohana mau ʻia e etch castings, stainless steel a me nā mea hana ʻē aʻe.
(2) No nā mea hana kila, hiki ke hoʻohana ʻia ka waika hydrofluoric haʻahaʻa no ka wehe ʻana i ka ʻōpala.Hydrofluoric acid solution me 70% concentration he hopena passivation ma ke kila
(3) Hydrofluoric acid me ka manaʻo o ma kahi o 10% i ka hopena corrosion nāwaliwali ma luna o ka magnesium a me kona mau alahele, no laila hoʻohana pinepine ʻia i ka etching o nā mea hana magnesium.
(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 ka meaʻawaʻawa a me ka maʻalahi, a ua hoʻohanaʻia e pale i ka pilina kanaka me ka waiʻona hydrofluoric a me ke kinoea hydrogen fluoride, ua hoʻopaʻa maikaʻiʻia ka pahu etching a loaʻa kahi mea hoʻoheheʻe maikaʻi, a hiki ke hoʻokuʻuʻia ka waiʻawaʻawa fluorinated.
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 ʻo ka graphite he kūpaʻa waika maikaʻi, ʻoi aku ka hiki ke kūʻē i ka waika hydrofluoric, ka mea e hoʻoholo ai hiki ke hoʻomaʻemaʻe ʻia ka graphite me ka waika hydrofluoric.ʻO ke kaʻina hana nui o ka hydrofluoric acid ka hoʻohui ʻana i ka graphite me ka waika hydrofluoric, a me ka hana ʻana i ka waika hydrofluoric 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.
Kūikawā no ka ʻeli ʻana o ka honua
ʻO ke ʻano o ka hoʻomākaukau ʻana o ka anhydrous rare earth fluoride, ʻo ia ka hoʻoheheʻe ʻana i ka hydrated rare earth fluoride mai ka wai wai, a laila hoʻomaʻemaʻe a hoʻoheheʻe ʻia i ka ʻohe honua laha me ka fluorinating agent.He liʻiliʻi loa ka solubility o ka fluoride honua, a hiki ke hoʻoheheʻe ʻia mai ka hydrofluoric, sulfuric, a i ʻole nitric acid solutions o ka honua rare me ka hoʻohana ʻana i ka waika hydrofluoric (ua hoʻokahe ʻia ka precipitate ma ke ʻano o ka fluoride hydrated).
ʻO TPT-LCD ka ʻemi ʻana o ka pale (māka uila)
Ma lalo o ka pale ʻana o ka photoresist a me ke kāʻei lihi, hoʻoponopono ʻia ka ʻike 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.Hiki i ka hoʻomaʻemaʻe hoʻomaʻemaʻe ʻana ke hoʻemi pono i ka ʻinoʻino o ka ʻili a hoʻemi i ka ua o nā mea hoʻopili keʻokeʻo.Hoʻoholo ʻia ka pilikia o ka ʻili a me ke keʻokeʻo adhesion precipitation.
ʻinoʻino fiber
Hydrofluoric acid piha corrosion photonic crystal fiber (PCF).Hoʻopiha ʻia ka waika Hydrofluoric i loko o nā pores o ka fiber crystal photonic i hohola ʻia.Ma ka hoʻololi ʻana i kāna ʻāpana ʻāpana keʻa, ua hoʻomohala ʻia ka fiber crystal photonic me kahi ʻano kikoʻī a hoʻololi ʻia kona conductivity optical.Hōʻike nā hopena i ka emi ʻana o ka nalowale o ka leakage a me ka hoʻopuehu ʻana me ka piʻi ʻana o ke degere corrosion porosity, ʻoi aku ka nui o ka coefficient nonlinear, ʻoi aku ka maikaʻi o ka refractive index o ka mold core a me ka index refractive like o ka cladding e hoʻemi like, a me ka wikiwiki o ka hui. hoololi hoi.
