IINKCUKACHA ZEMVELISO
Irhasi yeHydrogen fluoride iyanyibilika emanzini, kwaye isisombululo sayo samanzi sibizwa ngokubai-hydrofluoric acid.Imveliso idla ngokuba yi-35% -50% isisombululo se-aqueous yegesi ye-hydrogen fluoride, i-concentration ephezulu inokufikelela kwi-75%, kwaye ilulwelo olungenambala kunye olucacileyo lokutshaya.Ivumba elibi, eliguquguqukayo, elimhlophe lomsi emoyeni.Ngamandla aphakathi e-asidi ye-inorganic, eyonakalisa kakhulu, kwaye inokukhukulisa iglasi kunye ne-silicates ukuvelisa i-silicon tetrafluoride enegesi.Iyakwazi ukusebenzisana kunye neentsimbi, i-oxides yensimbi kunye ne-hydroxides ukwenza iityuwa ezahlukeneyo, kodwa umphumo awunamandla njenge-hydrochloric acid.Igolide, iplatinam, ilothe, iparafini kunye nezinye iiplastiki azisebenzi ngayo, ngoko ke kunokwenziwa izikhongozeli.Irhasi yeHydrogen fluoride kulula ukuyi polymerize, ukuyila (HF) 2 (HF) 3 · · iimolekyuli ze-iso-chain, kwimeko yolwelo, iqondo lepolymerization liyakhula.Gcina kwizikhongozeli ezenziwe ngelothe, iwax okanye iplastiki.Inetyhefu kakhulu kwaye inezilonda ekudibaneni kwesikhumba.
UKUSETYENZISWA KWEMVELISO
UHLELO LOMZIMBA
Ukulungiswa kwegraphite
I-Hydrofluoric acid yi-asidi eyomeleleyo enokuthi iphendule malunga naluphi na ukungcola kwi-graphite, kwaye i-graphite inokumelana ne-asidi efanelekileyo, ingakumbi iyakwazi ukumelana ne-hydrofluoric acid, emisela ukuba i-graphite inokuhlanjululwa nge-hydrofluoric acid.Inkqubo ephambili yendlela ye-hydrofluoric acid ngumxube we-graphite kunye ne-hydrofluoric acid, kunye nokuphendula kwe-hydrofluoric acid kunye nokungcola kwexesha elithile ukuvelisa izinto ezinyibilikayo okanye eziguquguqukayo, emva kokuhlamba ukususa ukungcola, ukuchithwa kwamanzi kunye nokomisa ukufumana igraphite ecocekileyo.
Umhlaba onqabileyo Unikezelwe
Ukulungiswa kwe-anhydrous enqabileyo yomhlaba fluoride kukuna kwemvula ye-hydrated enqabileyo yomhlaba i-fluoride evela kwisisombululo esimanzi, emva koko ukuphelelwa ngamanzi emzimbeni, okanye ukuchithwa ngokuthe ngqo kwee-oxides zomhlaba ezinqabileyo ezine-fluorinating agents.I-solubility ye-fluoride yomhlaba enqabileyo incinci kakhulu, kwaye ukusetyenziswa kwe-hydrofluoric acid kunokuyikhupha kwi-hydrochloric acid, i-sulfuric acid okanye isisombululo se-nitric acid yomhlaba onqabileyo (i-precipitate ikwimo ye-hydrated fluoride).
Unyango lomphezulu wesinyithi
Susa ukungcola okuphezu komhlaba okuqulethe ioksijini I-Hydrofluoric acid yiasidi ebuthathaka, efanayo ngokomelela kwi-asidi ye-formic.Ukugxininiswa ngokubanzi kwe-hydrofluoric acid ekhoyo ngokurhweba yi-30% ukuya kwi-50%.Iimpawu eziphambili ze-hydrofluoric acid ukususwa komhlwa zezi zilandelayo: (1) Iyakwazi ukunyibilikisa iikhompawundi ezine-silicon, i-aluminium, i-chromium kunye nezinye i-oxides zetsimbi nazo zine-solubility efanelekileyo, esetyenziswa ngokuqhelekileyo kwi-etch castings, insimbi engenasici kunye nezinye izinto zokusebenza.(2) Kwizinto zokusebenza zentsimbi kunye nentsimbi, i-hydrofluoric acid ephantsi ingasetyenziselwa ukususwa kwerusi.Isisombululo se-aqueous se-hydrofluoric acid kunye noxinzelelo lwe-70% sinempembelelo ye-passivation kwintsimbi (3) i-Hydrofluoric acid ene-concentration emalunga ne-10% inomhlwa obuthathaka kwi-magnesium kunye ne-alloys yayo, ngoko ke isetyenziswa ngokuphindaphindiweyo kwi-etching of workpieces ye-magnesium.(4) Ilothe ngokuqhelekileyo ayidliswa yihydrofluoric acid;I-Nickel inokumelana okuqinileyo kwizisombululo ze-hydrofluoric acid kunye noxinzelelo olukhulu kune-60%.I-Hydrofluoric acid inetyhefu kakhulu, kwaye iyaguquguquka, xa isetyenziselwa ukuthintela ukudibana kwabantu kunye nolwelo lwe-hydrofluoric acid kunye negesi ye-hydrogen fluoride, itanki ye-etching ivalwe kakuhle kwaye inesixhobo esilungileyo sokuphefumla, amanzi amdaka anokukhutshwa emva konyango.
Ukukha isanti yequartz
Isebenza ngcono xa iphathwa nge-hydrofluoric acid, kodwa ifuna ugxininiso oluphezulu.Xa kwabelwana nge-sodium dithionite, i-concentration ephantsi ye-hydrofluoric acid ingasetyenziswa.Uxinzelelo oluthile lwe-hydrochloric acid kunye nesisombululo se-hydrofluoric acid saxutywa kwi-quartz sand slurry ngexesha elifanayo ngokwemilinganiselo;Inokuphinda iphathwe ngesisombululo se-hydrochloric acid kuqala, ihlanjwe kwaye emva koko iphathwe nge-hydrofluoric acid, iphathwe kwiqondo lokushisa eliphezulu kwiiyure ezingama-2-3, kwaye emva koko ihlulwe kwaye ihlambuluke Ukungcola kunye ne-oxides phezu kwesanti ye-quartz inokususwa ngempumelelo, kwaye ukucoceka kunye nomgangatho wesanti ye-quartz unokuphuculwa.
I-FOCS Fiber corrosion
I-Hydrofluoric acid egcwalisa i-corrosion ye-photonic crystal fiber (PCF) yaphuhliswa.I-Hydrofluoric acid yazaliswa kumngxuma womoya we-photonic crystal fiber.Ngokutshintsha isakhiwo sayo secandelo lomnqamlezo, i-photonic crystal fiber enesakhiwo esithile yaphuhliswa ukuguqula ukukhanya kwayo.Iziphumo zibonisa ukuba ilahleko yokuvuza kunye nelahleko yokulahleka kwehle ngenqanaba lokubola komngxuma womoya we-photonic crystal fibre, i-coefficient engahambelaniyo iyanda ngokucacileyo, isalathiso esisebenzayo se-refractive semowudi engundoqo kunye nesalathiso esilinganayo sokuncipha kwe-cladding ngokuhambelanayo, kunye nokusasazwa kwesantya seqela nako kuyatshintsha.
IBANGA LE-ELECTRONIC
TPT-LCD ukucutha isikrini
Ngaphantsi kokukhuselwa kwe-photoresist kunye ne-border glue, i-concentration ye-hydrofluoric acid ihlengahlengiswa, inani elithile le-nitric acid, i-sulfuric acid egxininisiweyo kunye ne-hydrochloric acid yongezwa, kunye neemeko ezincedisayo ze-ultrasonic zongezwa, isantya se-etching ngokucacileyo siphuculwe.Ubunzima bomphezulu buncitshiswe ngokufanelekileyo ngokutshintshana kweenkqubo zokucoca, kwaye imvula yeziqhotyoshelo ezimhlophe ziyancipha.Sombulula ingxaki yomphezulu orhabaxa kunye ne-white adhesion surface precipitate.
