ZINTHU ZONSE

Mpweya wa hydrogen fluoride umasungunuka m'madzi, ndipo njira yake yamadzimadzi imatchedwahydrofluoric acid.The mankhwala nthawi zambiri 35% -50% njira amadzimadzi wa hydrogen fluoride mpweya, ndende apamwamba akhoza kufika 75%, ndipo colorless ndi momveka kusuta madzi.Fungo lamphamvu, losakhazikika, utsi woyera mumlengalenga.Ndi asidi yapakatikati yamphamvu, yowononga kwambiri, ndipo imatha kuwononga magalasi ndi ma silicates kuti ipange mpweya wa silicon tetrafluoride.Itha kuyanjananso ndi zitsulo, zitsulo zachitsulo ndi ma hydroxides kuti apange mchere wosiyanasiyana, koma zotsatira zake sizikhala zolimba ngati hydrochloric acid.Golide, platinamu, lead, parafini ndi mapulasitiki ena sagwira nawo ntchito, motero zotengera zimatha kupanga.Mpweya wa haidrojeni fluoride ndi wosavuta kuyimitsa, kupanga (HF) 2 (HF) 3 · · mamolekyu a iso-chain, mumadzimadzi, kuchuluka kwa polymerization kumawonjezeka.Sungani muzitsulo zopangidwa ndi mtovu, sera kapena pulasitiki.Ndiwowopsa kwambiri ndipo amatupa zilonda pakhungu.

KUGWIRITSA NTCHITO PRODUCT

INDUSTRIAL giredi

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 kugonjetsedwa ndi hydrofluoric acid, yomwe imatsimikizira kuti graphite ikhoza kuyeretsedwa ndi hydrofluoric acid.Waukulu ndondomeko ya hydrofluoric asidi njira ndi chisakanizo cha graphite ndi hydrofluoric acid, ndi zimene asidi hydrofluoric ndi zosafunika kwa nthawi kubala zinthu sungunuka kapena volatiles, pambuyo kutsuka kuchotsa zosafunika, madzi m'thupi ndi kuyanika kupeza woyeretsedwa graphite.

Osowa Dziko Lodzipereka

Kukonzekera kwa anhydrous rare earth fluoride ndi mvula ya hydrated rare earth fluoride kuchokera mumadzi amadzimadzi, kenako kutaya madzi m'thupi, kapena fluorination mwachindunji asomwe earth oxides ndi fluorinating agents.Kusungunuka kwa fluoride osowa padziko lapansi ndikochepa kwambiri, ndipo kugwiritsa ntchito hydrofluoric acid kumatha kuyimitsa kuchokera ku hydrochloric acid, sulfuric acid kapena nitric acid solution ya osowa lapansi (kuthamanga kuli mu mawonekedwe a hydrated fluoride).

Metal pamwamba mankhwala

Chotsani zonyansa zomwe zili ndi okosijeni Hydrofluoric acid ndi asidi wofooka, wofanana ndi mphamvu ya formic acid.Kuchuluka kwa hydrofluoric acid yomwe imapezeka pamalonda ndi 30% mpaka 50%.Mbali yaikulu ya hydrofluoric acid dzimbiri kuchotsa ndi motere: (1) Angathe kusungunula pakachitsulo munali mankhwala, zotayidwa, chromium ndi oxides ena zitsulo amakhalanso ndi solubility wabwino, ambiri ntchito etch castings, zitsulo zosapanga dzimbiri ndi workpieces ena.(2) Kwa zitsulo ndi chitsulo workpieces, otsika ndende hydrofluoric asidi angagwiritsidwe ntchito kuchotsa dzimbiri.Njira yamadzimadzi ya hydrofluoric acid yokhala ndi 70% imakhala ndi chitsulo (3) Hydrofluoric acid yokhala ndi pafupifupi 10% imakhala ndi dzimbiri lofooka pa magnesium ndi ma aloyi 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 zoposa 60%.Hydrofluoric acid ndi poyizoni kwambiri, ndi kusakhazikika, pamene ntchito kuteteza anthu kukhudzana ndi hydrofluoric asidi madzi ndi hydrogen fluoride mpweya, etching thanki ndi bwino losindikizidwa ndipo ali ndi mpweya wabwino chipangizo, fluorinated zinyalala akhoza kutulutsidwa pambuyo mankhwala.

Kutola mchenga wa quartz

Zimagwira ntchito bwino zikagwiritsidwa ntchito ndi hydrofluoric acid, koma zimafunikira kukhazikika kwambiri.Mukagawidwa ndi sodium dithionite, madontho ochepa a hydrofluoric acid angagwiritsidwe ntchito.Kuchuluka kwa hydrochloric acid ndi hydrofluoric acid solution adasakanizidwa mu slurry ya mchenga wa quartz nthawi yomweyo molingana ndi gawo;Itha kuthandizidwanso ndi yankho la hydrochloric acid poyamba, kutsukidwa ndikuthandizidwa ndi hydrofluoric acid, kuchitiridwa kutentha kwambiri kwa maola 2-3, kenako kusefedwa ndikutsukidwa Zoyipa ndi ma oxides pamtunda wa mchenga wa quartz zitha kuchotsedwa bwino, ndipo chiyero ndi mtundu wa mchenga wa quartz ukhoza kusinthidwa.

FOCS Fiber dzimbiri

Hydrofluoric acid filling corrosion of photonic crystal fiber (PCF) idapangidwa.Hydrofluoric acid idadzazidwa mu dzenje la mpweya la ulusi wa photonic crystal.Posintha mawonekedwe ake a mtanda, chithunzithunzi cha kristalo cha photonic chokhala ndi mawonekedwe apadera chinapangidwa kuti chisinthe kuwala kwake.Zotsatira zikuwonetsa kuti kutayika kwa kutayikira ndi kutayika kwakubalalika kumachepa ndi kuchuluka kwa dzimbiri kwa dzenje la mpweya wa Photonic crystal CHIKWANGWANI, kofananira kopanda mzere kumawonjezeka mwachiwonekere, cholozera chowoneka bwino chamayendedwe apakatikati ndi chofananira chofananira cha kubisala kutsika molingana, ndipo kuchuluka kwa liwiro la gulu kumasinthanso.

ELECTRONIC GRADE

Kuchepetsa skrini ya TPT-LCD

Pansi pa chitetezo cha photoresist ndi malire guluu, ndende ya hydrofluoric asidi ndi kusinthidwa, ena kuchuluka kwa nitric acid, anaikira sulfuric acid ndi hydrochloric asidi anawonjezera, ndi akupanga wothandiza zinthu anawonjezera, ndi etching mlingo mwachionekere bwino.Kuuma kwapamtunda kumachepetsedwa bwino posinthana njira zoyeretsera, ndipo kugwa kwa zolumikizira zoyera kumachepetsedwa.Kuthetsa vuto la akhakula pamwamba ndi woyera pamwamba adhesion precipitate.
