Acide Hydrofluoric （HF）

Hydrofluoric Acide （HF Image Ishusho Yerekanwe

ibisobanuro bigufi:

Ni igisubizo cyamazi ya gaz ya hydrogène fluoride, ikaba ari mucyo, idafite ibara, itabi ryangiza kandi rifite impumuro nziza.Acide Hydrofluoric ni aside idakabije kwangirika cyane, ibora cyane ibyuma, ibirahuri hamwe na silikoni irimo ibintu.Guhumeka umwuka cyangwa guhura nuruhu birashobora gutera gutwika bigoye gukira.Muri rusange laboratoire ikozwe muri fluor (igice nyamukuru ni calcium fluoride) hamwe na acide sulfurike yibanze, igomba gufungwa mumacupa ya plastike ikabikwa ahantu hakonje.

Umwuka wa hydrogène fluoride ushonga mumazi, kandi igisubizo cyamazi cyacyo cyitwa hydrofluoric aside.Ubusanzwe ibicuruzwa ni 35% -50% hydrogène fluoride ya gazi yumuti wamazi, ubunini bwinshi bushobora kugera kuri 75%, kumazi yumwotsi utagira ibara.Impumuro nziza, ihindagurika, umwotsi wera mu kirere.Nimbaraga ziciriritse acide organique yangirika cyane kandi irashobora kwangirika ibirahuri na silikate kugirango ibe gaze ya silicon tetrafluoride.Irashobora kandi gukorana nicyuma, okiside yicyuma na hydroxide kugirango ikore imyunyu itandukanye, ariko ingaruka ntabwo zikomeye nka acide hydrochloric.Zahabu, platine, isasu, paraffine na plastiki zimwe ntibishobora kubikoresha, bityo ibikoresho birashobora gukorwa.Gazi ya hydrogène ya hydrogène irashobora guhindurwa muburyo bworoshye kugirango ikore (HF) 2 (HF) 3 · molekile ya homochain, kandi mugihe cyamazi, urugero rwa polymerisation rwiyongera.Bika mu bikoresho bikozwe mu isasu, ibishashara cyangwa plastiki.Nuburozi cyane kandi burashobora gukomeretsa iyo uhuye nuruhu.

Imikoreshereze y'ibicuruzwa

Quartz umucanga

Ikora neza iyo ivuwe na acide hydrofluoric, ariko birakenewe kwibanda cyane.Iyo usangiwe na sodium disulfite, hashobora gukoreshwa ingufu za acide hydrofluoric.Ubwinshi bwa acide hydrochloric na acide hydrofluoric bivangwa na minisiteri ya quartz icyarimwe ukurikije igipimo;Irashobora kandi kuvurwa hakoreshejwe aside hydrochloric yabanje, gukaraba hanyuma ikavurwa na acide hydrofluoric, ikavurwa nubushyuhe bwinshi mumasaha 2-3, hanyuma ikayungurura kandi igasukurwa, ishobora gukuraho neza umwanda na okiside hejuru yumusenyi wa quartz kandi bigatera imbere ubuziranenge nubwiza bwumusenyi wa quartz.

Kuvura ibyuma

Kuraho hejuru ya ogisijeni irimo umwanda, aside hydrofluoric ni aside idakomeye, isa nimbaraga za aside.Ubwinshi bwa acide hydrofluoric iboneka mubucuruzi ni 30% kugeza 50%.Ibintu nyamukuru biranga hydrofluoric acide ingese ni ibi bikurikira:

(2) Kubikoresho byibyuma, acide hydrofluoric nkeya irashobora gukoreshwa mugukuraho ingese.Hydrofluoric acide hamwe na 70% yibitekerezo bigira ingaruka za passivation kumyuma

(4) Isasu muri rusange ntabwo ryangirika na aside hydrofluoric;Nickel ifite imbaraga zo guhangana na hydrofluoric acide hamwe nibitekerezo birenga 60%.Acide Hydrofluoric ifite uburozi bukabije kandi ihindagurika, kandi ikoreshwa mu gukumira abantu guhura na hydrofluoric aside ya hydrogène na hydrogène fluoride, ikigega cya ething gifunze neza kandi gifite igikoresho cyiza cyo guhumeka, kandi amazi y’amazi yatunganijwe arashobora gusohoka.

Gutunganya ibishushanyo

Acide Hydrofluoric ni aside ikomeye ishobora kwitwara hafi ya grafite yose, kandi grafite ifite aside irwanya aside, cyane cyane irashobora kurwanya aside hydrofluoric, igena ko grafite ishobora kwezwa na aside hydrofluoric.Inzira nyamukuru yuburyo bwa hydrofluoric ni ukuvanga grafite na acide hydrofluoric, hanyuma ugahindura aside hydrofluoric hamwe n’umwanda mugihe runaka kugirango ubyare ibintu bishonga cyangwa ibinyabuzima, nyuma yo gukaraba kugirango ukureho umwanda, umwuma no gukama kugirango ubone grafite isukuye.

Umwihariko wo gucukura isi idasanzwe

Uburyo bwo gutegura floride ya anhydrous idasanzwe ni ukugabanya amazi ya fluoride yisi idasanzwe ivuye mumuti wamazi, hanyuma igahindura umwuma cyangwa florine oxyde yisi idasanzwe hamwe na fluorine.Ihindagurika rya fluoride idasanzwe ni ntoya cyane, kandi irashobora gutwarwa na hydrofluoric, sulfurike, cyangwa acide nitricike yubutaka budasanzwe ukoresheje aside hydrofluoric (imvura igwa muburyo bwa fluoride hydrated).

TPT-LCD Kugabanuka Mugaragaza (Icyiciro cya elegitoroniki)

Mu rwego rwo kurinda fotoreziste hamwe na kole, inkombe ya acide hydrofluoric irahindurwa, umubare munini wa acide ya nitric, aside sulfurike yibanze hamwe na aside hydrochloric wongeyeho, kandi hiyongereyeho imiterere yubufasha bwa ultrasonic, igipimo cyo gutera neza kiragaragara neza.Ubundi buryo bwo gukora isuku burashobora kugabanya neza ububobere bwubuso no kugabanya imvura yimigozi yera.Ikibazo cyubuso bukabije nubuso bwera bwimvura igwa byakemutse.

Kwangirika kwa fibre

Acide Hydrofluoric yuzuyemo ruswa ya fotonike ya kirisiti (PCF).Acide Hydrofluoric yujujwe mu byobo bya fibre irambuye ya fotonike.Muguhindura ibice byambukiranya ibice, fotonike ya kristal fibre ifite imiterere yihariye iratera imbere kandi optique ya optique irahinduka.Ibisubizo byerekana ko igihombo cyo kumeneka hamwe no gutakaza igabanuka bigabanuka hamwe no kwiyongera kwurwego rwo kwangirika kwangirika, coefficente idafite umurongo yiyongera kuburyo bugaragara, indangagaciro nziza yo kwangirika yibibumbano byibanze hamwe nibipimo bihwanye no kwangirika kwambarwa bigabanuka bikwiranye, hamwe nitsinda ryihuta ryitsinda. nayo irahinduka.
