I-Hydrofluoric acid (hf)

Incazelo emfushane:

Yisisombululo esinamanzi se-hydrogen fluoride gesi, okuwuketshezi olusobala, olungenamibala, olubhemayo ngephunga eliqinile le-pungent. I-Hydrofluoric acid iyi-acid enobuthakathaka ngokweqile, esebenza kakhulu kwizinsimbi, ingilazi kanye nezinto eziqukethe ama-silicon. Ukuphefumula komusi noma ukuxhumana nesikhumba kungadala ukushiswa okunzima ukwelapha. Ilebhu ngokuvamile yenziwa nge-fluoria (ingxenye enkulu yi-calcium fluoride) kanye ne-sulfuric acid, okudinga ukuvalwa ebhodleleni lepulasitiki futhi kugcinwe endaweni epholile.

(Ububanzi bereferensi yesicelo 'Ukusetshenziswa Komkhiqizo')

Igesi ye-Hydrogen Fluoride i-soluble emanzini, futhi ikhambi layo lamanzi libizwa ngokuthi i-hydrofluoric acid. Umkhiqizo uvame ukuba ngu-35% -50% we-hydrogen fluoride wegesi igesi, okuhlushwa okuphezulu kungafinyelela kuma-75%, ngoketshezi olucacisiwe olucacisiwe. Ngiphunga impango, eguquguqukayo, intuthu emhlophe emoyeni. Kuyinto amandla aphakathi e-Inorganic acid awonaka kakhulu futhi angalungisa ingilazi nezilimo ukuze zakhe i-gaseous silicon tetrafluide. Ingasebenzisana nezinsimbi, insimbi oxides kanye nama-hydroxides ukwakha usawoti ahlukahlukene, kepha umphumela awunamandla njenge-hydrochloric acid. Igolide, iplatinamu, ukuhola, uphalafini kanti amanye amapulasitiki awakwazi ukuyisebenzisa, ngakho-ke kungenzeka ukuthi izitshani zingenziwa. I-Hydrogen Fluoride gesi ifakwe kalula i-polymerized ukuze kwakhiwe (hf) 2 (hf) 3 (HF) 3 · Homochain molecule, kanye nesimo se-polymerization inyuka. Gcina ezitsheni ezenziwe ngokuhola, i-wax noma ipulasitiki. Kuyinto enobuthi kakhulu futhi ingakwazi ukuxhumana nokuxhumana kwesikhumba.

Ukusetshenziswa Komkhiqizo

Ukuthathwa kwesihlabathi se-Quartz

Isebenza kangcono lapho iphathwa nge-hydrofluoric acid, kepha ukugxila okuphezulu kuyadingeka. Lapho kwabelwane nge-sodium uhlaka, ukugxila okuphansi kwe-hydrofluoric acid kungasetshenziswa. Ukuqoqwa okuthile kwe-hydrochloric acid kanye ne-hydrofluoric acid solution kuxutshwe nodaka lwe-quartz ngasikhathi sinye ngokuya ngokulingana; Kungaphathwa futhi nge-hydrochloric acid solution kuqala, kugezwe bese kuphathwa nge-hydrofluoric acid, bese kuhlanzwa futhi kuhlanziwe ngokuphumelelayo, kungasusa ngempumelelo ukungcola kanye nekhwalithi yesihlabathi se-quartz.

Ukwelashwa okungaphezulu kwensimbi

Susa ukungcola okuqukethe i-oxygen-oxygen, i-hydrofluoric acid iyi-acid ebuthakathaka, efana namandla ku-formic acid. Ukuqoqwa okujwayelekile kwe-hydrofluoric acid etholakala nge-30% kuya ku-50%. Izici eziyinhloko zokususwa kokugqwala kwe-hydrofluoric kungokulandelayo:

(2) Ngezisebenzi zensimbi, i-hydrofluoric ephansi ephansi ingasetshenziselwa ukususwa kokugqwala. Isixazululo se-Hydrofluoric acid ngo-70% okuhlushwa sinomphumela wokudlula kwensimbi

(4) Ukuhola ngokuvamile akunakugcwaliswa yi-hydrofluoric acid; I-nickel inokumelana okuqinile kwezixazululo ze-hydrofluoric acid ngokugxila ezinkulu kune-60%. I-Hydrofluoric acid inobuthi obunobuthi futhi iguquguqukayo, futhi isetshenziselwa ukuvikela ukuxhumana nabantu nge-hydrofluoric acid uketshezi kanye ne-hydrogen fluoride gesi, i-etching tank ivalwe kahle futhi ine-wandwing wastewaterated wastewate.

Ukucutshungulwa kwe-Graphite

I-Hydrofluoric acid iyi-acid eqinile engasabela cishe kunoma yikuphi ukungcola okuku-graphite, futhi i-graphite inokumelana kahle ne-acid, ikakhulukazi ingamelana ne-graphite ye-hydrofluoric. Inqubo esemqoka ye-Hydrofluoric acid indlela ukuxuba i-graphite nge-hydrofluoric acid, bese usabela i-hydrofluoric acid ngokungcolisa izinto noma ama-volutiles, ngemuva kokugeza ukususa ukungcola, ukomisa emzimbeni wokuthola i-graphifite.

Ekhethekile yezokumbiwa phansi komhlaba

Indlela yokulungiselela umhlaba we-anhydrous engavamile i-fluoride ukunqanda umhlaba wamanzi we-hydrate areRre emhlabeni kusuka kwikhambi elinamanzi, bese ucwilisa umhlaba ongenawo noma uxhamazela umhlaba ongandile oxide oqondile nge-ejenti eshisayo ngqo. I-solubity ye-flubide yaseMhlabeni engandile incane kakhulu, futhi ingabhekelwa phansi kusuka ku-hydrofluoric, sulfuric, noma izixazululo ze-nitric acid yoMhlaba ongavamile usebenzisa i-hydrofluoric acid (i-preatipitate inembe ngendlela ye-fluoride egcwele i-hydrate).

I-TPT-LCD Screen Screen (ibanga le-elekthronikhi)

Ngaphansi kokuvikelwa kwe-Photoresist kanye ne-glue enqenqemeni, ukuhlanganiswa kwe-hydrofluoric acid kuyalungiswa, inani elithile le-nitric acid, i-hydrochloric acid yengezwa, futhi kufakwe izilinganiso zokulwa ze-ultrasonic, kusobala ukuthi kuthuthukiswa izilinganiso. Ukuhlanza Ukuhlanza kunganciphisa ngempumelelo ubulukhuni bendawo futhi kunciphise imvula yezinamathiseli ezimhlophe zangaphandle. Inkinga yendawo enolaka kanye nokuchazwa komhlaba okumhlophe okuvinjelwe kuxazululwa.

Ukugqwala kwe-fiber

I-Hydrofluoric acid egcwele i-Crystal Fiber (PCF). I-Hydrofluoric acid igcwele kuma-pores we-Photonic Crystal Fibre. Ngokushintsha isakhiwo sayo seSiphambano seSigaba, i-Photonic Crystal Fibre ngesakhiwo esithile siyathuthukiswa kanti nokusebenza kwalo okubonakalayo kuguquliwe. Imiphumela ikhombisa ukuthi ukulahleka okuvuzayo nokulahleka kokulahleka kokwenyuka kwe-porosion corrosion degree, i-nonlinear corlosion inyuka ngokusobala, inkomba yokuvunyelwa okusebenzayo yokuhlanza okuyisisekelo kanye nokuhlakazeka kwe-velocity yeqembu kuyashintsha.
