kanye neminye imikhiqizo ethile ekufanele kakhulu izimo zakho zokusebenzisa , futhi ikunikeze amasampuli amahhala.
IMINININGWANE YOMKHIQIZO
Igesi ye-Hydrogen fluoride iyancibilika emanzini, futhi isisombululo sayo esinamanzi sibizwai-hydrofluoric acid.Umkhiqizo uvamise ukuba yisisombululo se-aqueous esingu-35% -50% segesi ye-hydrogen fluoride, ukuhlushwa okuphezulu kakhulu kungafinyelela ku-75%, futhi kuwuketshezi olubhemayo olungenambala nolucacisiwe.Iphunga elimnandi, elishisayo, intuthu emhlophe emoyeni.Kuyi-asidi yamandla aphakathi nendawo, egqwala kakhulu, futhi ingaguguleka ingilazi nama-silicates ukukhiqiza i-silicon tetrafluoride enegesi.Ingakwazi futhi ukusebenzisana nezinsimbi, i-metal oxides nama-hydroxides ukwakha usawoti ohlukahlukene, kodwa umphumela awunamandla njenge-hydrochloric acid.Igolide, iplatinamu, umthofu, upharafini namanye amapulasitiki awasebenzi ngawo, ngakho izitsha zingenziwa.Igesi ye-Hydrogen fluoride kulula ukupholisa, ukwakha (HF) 2 (HF) 3 · · I-iso-chain molecules, esimweni se-liquid, izinga le-polymerization liyakhula.Gcina ezitsheni ezenziwe ngomthofu, i-wax noma ipulasitiki.Inobuthi obukhulu futhi izilonda ekuthinteni isikhumba.
UKUSETSHENZISWA KOMKHIQIZO
IBANGA LEZIMBUNDU
Ukucutshungulwa kwe-graphite
I-Hydrofluoric acid iyi-asidi eqinile engasabela cishe nganoma yikuphi ukungcola ku-graphite, futhi i-graphite inokumelana ne-asidi enhle, ikakhulukazi ingamelana ne-hydrofluoric acid, enquma ukuthi i-graphite ingahlanzwa nge-hydrofluoric acid.Inqubo eyinhloko ye-hydrofluoric acid indlela iyinhlanganisela ye-graphite ne-hydrofluoric acid, kanye nokusabela kwe-hydrofluoric acid nokungcola isikhathi esithile ukukhiqiza izinto ezincibilikayo noma ama-volatiles, ngemva kokugeza ukuze kukhishwe ukungcola, ukuphelelwa amandla kwamanzi nokomisa ukuze uthole i-graphite ehlanzekile.
Umhlaba ongavamile Unikezelwe
Ukulungiswa kwe-anhydrous rare earth fluoride kuwukuna kwe-fluoride yomhlaba eyi-hydrated engavamile kusuka kusisombululo esinamanzi, bese ukuphelelwa amanzi emzimbeni, noma ukukhishwa okuqondile kwama-oxides omhlaba ane-fluorinating agents.I-solubility ye-earth fluoride engavamile incane kakhulu, futhi ukusetshenziswa kwe-hydrofluoric acid kungayinciphisa isuka ku-hydrochloric acid, i-sulfuric acid noma isisombululo se-nitric acid somhlaba ongavamile (i-precipitate isesimweni se-hydrated fluoride).
Ukwelashwa kwendawo yensimbi
Susa ukungcola okungaphezulu okuqukethe umoya-mpilo I-Hydrofluoric acid iyi-asidi ebuthakathaka, efana ngamandla ne-asidi ye-formic.I-concentration evamile ye-hydrofluoric acid etholakala ngokuthengiswayo ingama-30% kuya ku-50%.Izici eziyinhloko zokususwa kokugqwala kwe-hydrofluoric acid zimi kanje: (1) Ingancibilikisa izinhlanganisela eziqukethe i-silicon, i-aluminium, i-chromium namanye ama-oxide ensimbi abuye abe nokuncibilika okuhle, okuvame ukusetshenziselwa ukuhlanganisa ama-castings, insimbi engagqwali nezinye izinto zokusebenza.(2) Ngensimbi nensimbi, i-hydrofluoric acid ephansi ingasetshenziselwa ukususa ukugqwala.Isixazululo se-aqueous se-hydrofluoric acid esine-concentration engu-70% sinomthelela wokunciphisa insimbi (3) I-Hydrofluoric acid ene-concentration engaba ngu-10% inokugqwala okubuthakathaka ku-magnesium nama-alloys ayo, ngakho-ke ivame ukusetshenziselwa ukushumeka kwezinto zokusebenza ze-magnesium.(4) Umthofu ngokuvamile awugqwali nge-hydrofluoric acid;I-Nickel inokumelana okuqinile kuzixazululo ze-hydrofluoric acid ezinokugxila okukhulu kuno-60%.I-Hydrofluoric acid inobuthi obuphezulu, futhi iyaguquguquka, uma isetshenziselwa ukuvimbela ukuthintana komuntu ne-hydrofluoric acid liquid kanye negesi ye-hydrogen fluoride, ithangi lokufaka i-etching livalwa kangcono futhi linomshini omuhle wokungenisa umoya, amanzi angcolile ane-fluorinated angakhishwa ngemva kokwelashwa.
Ukukhethwa kwesihlabathi se-quartz
Isebenza kangcono uma iphathwa nge-hydrofluoric acid, kodwa idinga ukugxila okuphezulu.Uma kwabelwana nge-sodium dithionite, ukugxila okuphansi kwe-hydrofluoric acid kungasetshenziswa.Ukuhlushwa okuthile kwe-hydrochloric acid nesisombululo se-hydrofluoric acid kwaxutshwa ku-slurry yesihlabathi se-quartz ngesikhathi esifanayo ngokuya ngesilinganiso;Ingase futhi iphathwe ngesisombululo se-hydrochloric acid kuqala, igeze bese iphathwa nge-hydrofluoric acid, iphathwe ngokushisa okuphezulu amahora angu-2-3, bese ihlungwa futhi ihlanzwe Ukungcola nama-oxide ebusweni besihlabathi se-quartz kungasuswa ngokuphumelelayo, futhi ukuhlanzeka kanye nekhwalithi yesihlabathi se-quartz kungathuthukiswa.
I-FOCS Fiber corrosion
I-Hydrofluoric acid filling corrosion ye-photonic crystal fiber (PCF) yasungulwa.I-Hydrofluoric acid yagcwaliswa emgodini womoya we-photonic crystal fiber.Ngokushintsha isakhiwo sayo sesiphambano, i-photonic crystal fiber enesakhiwo esithile yathuthukiswa ukuze iguqule ukukhanya kwayo.Imiphumela ibonisa ukuthi ukulahlekelwa ukuvuza nokulahlekelwa okuhlakazekayo kwehla nge-corrosion degree yembobo yomoya ye-photonic crystal fibre, i-coefficient engaqondile ikhuphuka ngokusobala, inkomba esebenzayo ye-refractive yemodi eyinhloko kanye nenkomba ye-refractive efanayo ye-cladding iyancipha ngokuhambisanayo, kanye nokuhlakazeka kwesivinini seqembu nakho kuyashintsha.
ELECTRONIC IBANGA
Ukunciphisa isikrini se-TPT-LCD
Ngaphansi kokuvikelwa kwe-photoresist kanye ne-border glue, ukuhlushwa kwe-hydrofluoric acid kulungiswa, inani elithile le-nitric acid, i-concentrate sulfuric acid kanye ne-hydrochloric acid yengezwe, futhi izimo ezisizayo ze-ultrasonic zengezwe, izinga lokugubha ngokusobala lithuthukisiwe.Ubulukhuni obungaphezulu buncishiswa ngempumelelo ngokushintshana kwezinqubo zokuhlanza, futhi imvula yezinto ezinamathiselwe endaweni emhlophe iyancipha.Xazulula inkinga yendawo emagebhugebhu kanye nemvula yokunamathela emhlophe.
