Kushandiswa Kwechigadzirwa
Quartz jecha pickling
Inoshanda zvakanyanya kana yakarapwa ne hydrofluoric acid, asi yakanyanya kutariswa inodiwa.Kana yakagovaniswa nesodium disulfite, yakaderera kudzika kwehydrofluoric acid inogona kushandiswa.Imwe mutsara wehydrochloric acid uye hydrofluoric acid solution yakasanganiswa mumatope equartz panguva imwe chete maererano nehuwandu;Inogonawo kurapwa ne hydrochloric acid solution kutanga, yakashambidzwa uye yozobatwa ne hydrofluoric acid, inobatwa pakupisa kwemaawa 2-3, uye yozopepetwa uye kucheneswa, iyo inogona kunyatsobvisa tsvina uye oxides pamusoro pejecha requartz uye kuvandudza. kuchena uye kunaka kwejecha requartz.
Metal pamusoro kurapwa
Bvisa pamusoro peokisijeni-ine tsvina, hydrofluoric acid iasidhi isina simba, yakafanana musimba kune formic acid.Kuwanda kwehuwandu hwekutengesa kunowanikwa hydrofluoric acid ndeye 30% kusvika 50%.Hunhu hukuru hwekubvisa hydrofluoric acid ngura ndeaya anotevera:
(1) Inogona kunyungudutsa silicon-ine makomisheni, aruminiyamu, chromium uye mamwe simbi oxides zvakare ine yakanaka solubility, inowanzoshandiswa etch castings, Stainless simbi uye mamwe maworkpieces.
(2) Yesimbi yekushanda, yakaderera hydrofluoric acid inogona kushandiswa kubvisa ngura.Hydrofluoric acid mhinduro ine 70% yekumisikidza ine passivation mhedzisiro pasimbi
(3) Hydrofluoric asidhi ine muunganidzwa ingangoita gumi muzana ine isina kusimba corrosion mhedzisiro pa magnesium nema alloys ayo, saka inowanzoshandiswa mu etching ye magnesium workpieces.
(4) Mutobvu hauwanzosvibiswa nehydrofluoric acid;Nickel ine kupikisa kwakasimba muhydrofluoric acid solutions ine maconcentrations anopfuura 60%.Hydrofluoric acid ine muchetura uye inovhuvhuta, uye inoshandiswa kudzivirira kusangana kwevanhu nehydrofluoric acid fluid uye hydrogen fluoride gasi, etching tank inovharwa zvakanyanya uye ine yakanaka yekufemesa mudziyo, uye yakagadziriswa fluorinated tsvina inogona kubudiswa.
Graphite processing
Hydrofluoric asidhi yakasimba asidhi inogona kuita pamwe nekusachena chero kupi zvako mugraphite, uye graphite ine yakanaka acid resistance, kunyanya inogona kuramba hydrofluoric acid, iyo inosarudza kuti graphite inogona kucheneswa nehydrofluoric acid.Nzira huru ye hydrofluoric acid nzira ndeyekusanganisa graphite ne hydrofluoric acid, uye kuita hydrofluoric acid nekusvibiswa kwekanguva kuti ibudise zvinhu zvinonyunguduka kana zvinoputika, mushure mekugeza kubvisa tsvina, kupera simba uye kuomesa kuti uwane girafu yakacheneswa.
Yakakosha yekuchera pasi isingawanzo
Iyo nzira yekugadzirira yeanhydrous isingawanzo pasi fluoride ndeye kunayisa hydrated isingawanzo pasi fluoride kubva kune aqueous solution, uye wozobvisa mvura kana fluorinate isingawanzo pasi oxide zvakananga ne fluorinating agent.Kunyungudika kwepasi risingawanzoitwa fluoride idiki kwazvo, uye inogona kudhindwa kubva kuhydrofluoric, sulfuric, kana nitric acid mhinduro dzepasi isingawanzo kushandisa hydrofluoric acid (iyo mvura inonaya muchimiro chehydrated fluoride).
TPT-LCD Screen thinning (Electronic giredhi)
Pasi pekuchengetedzwa kwe photoresist uye edge glue, iyo hydrofluoric acid inogadziriswa, imwe chiyero che nitric acid, concentrated sulfuric acid uye hydrochloric acid inowedzerwa, uye iyo ultrasonic aixiliary mamiriro anowedzerwa, iyo etching rate iri pachena inovandudzwa.Alternating yekuchenesa inogona kunyatso kudzikisa kushata kwepasi uye kuderedza kunaya kwewhite surface attachment.Dambudziko re rough surface uye white surface adhesion precipitation inogadziriswa.
Fiber corrosion
Hydrofluoric acid yakazadza corrosion photonic crystal fiber (PCF).Hydrofluoric acid inozadzwa mumapores eiyo yakatambanudzwa photonic crystal fiber.Nekushandura chimiro chayo chemuchinjiko, iyo photonic crystal fiber ine chaiyo chimiro inogadzirwa uye yayo optical conductivity inoshandurwa.Mhedzisiro yacho inoratidza kuti kurasikirwa kwekudonha uye kurasikirwa kwekurashikirwa kunodzikira nekuwedzera kweporosity corrosion degree, iyo isina mutsara coefficient inowedzera zviri pachena, iyo inoshanda refractive index yeiyo core mold uye yakaenzana refractive index ye cladding inoderera zvinoenderana, uye boka rekupararira kweboka. zvakare shanduko.
