Hydrofluoric Acid (HF)

Kufotokozera mwachidule:

Ndi njira yamadzimadzi ya mpweya wa hydrogen fluoride, womwe ndi wowonekera, wopanda mtundu, wosuta wamadzimadzi owononga ndi fungo lamphamvu.Hydrofluoric acid ndi asidi ofooka kwambiri owononga kwambiri, omwe amawononga kwambiri zitsulo, galasi ndi zinthu zomwe zili ndi silicon.Kukoka mpweya wa nthunzi kapena kukhudzana ndi khungu kungayambitse zilonda zomwe zimakhala zovuta kuchiza.Laborator nthawi zambiri imapangidwa ndi fluorite (chigawo chachikulu ndi calcium fluoride) ndi acidity ya sulfuric acid, yomwe imafunika kusindikizidwa mu botolo lapulasitiki ndikusungidwa pamalo ozizira.

Kugwiritsa Ntchito Mankhwala

Kutola mchenga wa quartz

Zimagwira ntchito bwino mukapatsidwa mankhwala a hydrofluoric acid, koma kuchuluka kwambiri kumafunika.Mukagawidwa ndi sodium disulfite, madontho ochepa a hydrofluoric acid angagwiritsidwe ntchito.Mulingo wina wa hydrochloric acid ndi hydrofluoric acid solution adasakanizidwa mumatope a quartz nthawi yomweyo molingana ndi kuchuluka;Itha kuthandizidwanso ndi yankho la hydrochloric acid poyamba, kutsukidwa kenako ndikuthandizidwa ndi hydrofluoric acid, kuchitiridwa pa kutentha kwakukulu kwa maola 2-3, kenako kusefedwa ndikutsukidwa, komwe kumatha kuchotsa zonyansa ndi ma oxides pamtunda wa mchenga wa quartz ndikuwongolera. chiyero ndi mtundu wa mchenga wa quartz.

Metal pamwamba mankhwala

Chotsani zonyansa zokhala ndi okosijeni, hydrofluoric acid ndi asidi ofooka, ofanana ndi mphamvu ya formic acid.Kuchuluka kwa hydrofluoric acid yomwe imapezeka pamalonda ndi 30% mpaka 50%.Makhalidwe akuluakulu a hydrofluoric acid kuchotsa dzimbiri ndi awa:

(1) Angathe kusungunula mankhwala okhala ndi silicon, aluminiyamu, chromium ndi oxides zina zazitsulo zimakhalanso ndi sungunuka wabwino, womwe umagwiritsidwa ntchito popanga ma castings, zitsulo zosapanga dzimbiri ndi zida zina.

(2) Pakuti workpieces zitsulo, otsika ndende hydrofluoric asidi angagwiritsidwe ntchito kuchotsa dzimbiri.Hydrofluoric acid yankho ndi 70% ndende ali passivation zotsatira pa chitsulo

(3) Hydrofluoric acid yokhala ndi ndende pafupifupi 10% imakhala ndi mphamvu yofooka ya magnesium ndi ma alloys ake, chifukwa chake imagwiritsidwa ntchito nthawi zambiri kuyika zida za magnesium.

(4) Mtovu nthawi zambiri suwotchedwa ndi hydrofluoric acid;Nickel ali ndi kukana kwambiri mu hydrofluoric acid mayankho ndi ndende zazikulu kuposa 60%.Hydrofluoric acid ndiyowopsa kwambiri komanso yosasunthika, ndipo imagwiritsidwa ntchito poletsa kukhudzana ndi anthu ndi madzi a hydrofluoric acid ndi mpweya wa hydrogen fluoride, thanki yotsekera imakhala yosindikizidwa bwino ndipo imakhala ndi chipangizo chabwino cholowera mpweya wabwino, ndipo madzi otayira opangidwa ndi fluorinated amatha kutayidwa.

Graphite processing

Hydrofluoric acid ndi asidi amphamvu omwe amatha kuchitapo kanthu ndi zonyansa zilizonse mu graphite, ndipo graphite imakhala ndi kukana kwa asidi, makamaka imatha kukana hydrofluoric acid, yomwe imatsimikizira kuti graphite ikhoza kuyeretsedwa ndi hydrofluoric acid.Waukulu ndondomeko ya hydrofluoric asidi njira ndi kusakaniza graphite ndi hydrofluoric asidi, ndi kuchita hydrofluoric asidi ndi zosafunika kwa nthawi kubala zinthu sungunuka kapena volatiles, pambuyo kutsuka kuchotsa zosafunika, kuchepa madzi m'thupi ndi kuyanika kupeza woyeretsedwa graphite.

Zapadera za migodi yosowa padziko lapansi

Njira yokonzekera ya anhydrous rare earth fluoride ndikutulutsa hydrated osowa padziko lapansi fluoride kuchokera mumadzi amadzimadzi, ndiyeno kukhetsa madzi kapena fluorinate osowa lapansi okusayidi mwachindunji ndi fluorinating wothandizira.Kusungunuka kwa fluoride osowa padziko lapansi ndikochepa kwambiri, ndipo kumatha kupangidwa kuchokera ku hydrofluoric, sulfuric, kapena nitric acid solutions of rare earth pogwiritsa ntchito hydrofluoric acid (precipitate imapangidwa ngati hydrated fluoride).

TPT-LCD Screen kupatulira (Electronic grade)

Pansi pa chitetezo cha photoresist ndi m'mphepete guluu, ndende ya hydrofluoric asidi ndi kusinthidwa, wina kuchuluka kwa nitric acid, anaikira sulfuric acid ndi hydrochloric acid ndi anawonjezera, ndi akupanga wothandiza zinthu anawonjezera, ndi etching mlingo mwachionekere bwino.Kuyeretsa kosinthasintha kumatha kuchepetsa kuuma kwapamwamba komanso kuchepetsa mpweya wa zomata zoyera.Vuto lalikulu pamwamba ndi woyera pamwamba adhesion mpweya kuthetsedwa.

Fiber dzimbiri

Hydrofluoric acid yodzaza corrosion photonic crystal fiber (PCF).Hydrofluoric acid imadzazidwa mu pores wa anatambasula photonic crystal ulusi.Posintha mawonekedwe ake a mtanda, chithunzithunzi cha kristalo cha photonic chokhala ndi mawonekedwe apadera chimapangidwa ndipo mawonekedwe ake owoneka bwino amasinthidwa.Zotsatira zikuwonetsa kuti kutayika kwa kutayikira ndi kutayika kwakubalalika kumachepa ndi kuchuluka kwa porosity corrosion degree, nonlinear coefficient ikuwonjezeka mwachiwonekere, refractive index of the core mold ndi ofanana refractive index of the cladding amachepetsa motere, ndi gulu liwiro kubalalitsidwa. komanso kusintha.
