PRODUCT DETAILS
Hydrogen fluoride gasi inonyungudika mumvura, uye mhinduro yayo ine aqueous inonzihydrofluoric asidhi.Chigadzirwa chacho kazhinji 35% -50% aqueous solution yehydrogen fluoride gasi, iyo yepamusoro-soro inogona kusvika 75%, uye imvura isina ruvara uye yakajekeswa yekusvuta.Hwema hunonhuwa, hunoputika, hutsi huchena mumhepo.Iyo iripakati simba inorganic acid, inoparadza zvakanyanya, uye inogona kukanganisa girazi uye silicates kugadzira gaseous silicon tetrafluoride.Inogonawo kupindirana nesimbi, metal oxides uye hydroxides kuumba munyu wakasiyana-siyana, asi mhedzisiro yacho haina kusimba sehydrochloric acid.Ndarama, platinamu, lead, parafini uye mamwe mapurasitiki haashande nawo, saka midziyo inogona kugadzirwa.Hydrogen fluoride gasi iri nyore kuita polymerize, kugadzira (HF) 2 (HF) 3 · · iso-cheni mamorekuru, munzvimbo yemvura, dhigirii repolymerization rinowedzera.Chengetedza mumidziyo yakagadzirwa nemutobvu, wakisi kana plastiki.Iyo ine muchetura zvakanyanya uye ine maronda pakubata kweganda.
KUSHANDISA PRODUCT
INDUSTRIAL giredhi
Graphite processing
Hydrofluoric acid iasidhi yakasimba iyo inogona kuita nechero kusvibiswa kwegraphite, uye graphite ine yakanaka acid inodzivirira, kunyanya inogona kupikisa hydrofluoric acid, iyo inosarudza kuti graphite inogona kucheneswa nehydrofluoric acid.Nzira huru ye hydrofluoric acid nzira ndeyekusanganiswa kwe graphite uye hydrofluoric acid, uye maitiro e hydrofluoric acid uye tsvina kwenguva yakati kuti ibudise zvinhu zvinonyunguduka kana zvinoputika, mushure mekugeza kubvisa tsvina, kupera simba uye kuomesa kuwana girafu yakacheneswa.
Rare pasi Rakatsaurirwa
Kugadziriswa kweanhydrous rare earth fluoride kunoitwa nekunaya kwe hydrated isingawanzo pasi fluoride kubva kune aqueous solution, ipapo kupera simba, kana kunangana fluorination yeasingawanzo pasi oxides ine fluorinating agents.Kunyungudika kwepasi risingawanzoitwa fluoride idiki kwazvo, uye kushandiswa kwehydrofluoric acid kunogona kuikonzeresa kubva kuhydrochloric acid, sulfuric acid kana nitric acid mhinduro yepasi isingawanzo (iyo inonaya iri muchimiro che hydrated fluoride).
Metal pamusoro kurapwa
Bvisa pamusoro peokisijeni-ine tsvina Hydrofluoric acid iasidhi isina simba, yakafanana mukusimba kune formic acid.Kuwanda kwehuwandu hwekutengesa kunowanikwa hydrofluoric acid ndeye 30% kusvika 50%.Izvo zvakakosha zve hydrofluoric acid kubvisa ngura ndezvizvi: (1) Inogona kunyungudutsa silicon-ine makomisheni, aruminiyamu, chromium uye mamwe maokisi esimbi anewo kunyungudika kwakanaka, kunowanzoshandiswa kumisa castings, simbi isina tsvina uye mamwe maworkpieces.(2) Yesimbi uye simbi workpieces, yakaderera concentration hydrofluoric acid inogona kushandiswa kubvisa ngura.Aqueous solution ye hydrofluoric acid ine 70% ine passivation effect pasimbi (3) Hydrofluoric acid ine concentration inosvika 10% ine huturu husina kusimba pa magnesium nema alloys ayo, saka inowanzoshandiswa pakuisa magnesium workpieces.(4) Mutobvu hauwanzosvibiswa nehydrofluoric acid;Nickel ine kupikisa kwakasimba muhydrofluoric acid solutions ine maconcentrations anopfuura 60%.Hydrofluoric acid ine muchetura zvakanyanya, uye inoshanduka, kana ichishandiswa kudzivirira kusangana kwevanhu nehydrofluoric acid fluid uye hydrogen fluoride gasi, etching tank inovharwa zvakanyanya uye ine yakanaka yekufemesa mudziyo, fluorinated tsvina inogona kuburitswa mushure mekurapwa.
Quartz jecha pickling
Inoshanda zvakanyanya kana yakarapwa nehydrofluoric acid, asi inoda yakanyanya kukwirisa.Kana yakagovaniswa ne sodium dithionite, yakaderera kudzika kwe hydrofluoric acid inogona kushandiswa.Imwe mutsara we hydrochloric acid uye hydrofluoric acid solution yakasanganiswa mu quartz jecha slurry panguva imwe chete maererano nehuwandu;Inogonawo kurapwa ne hydrochloric acid solution kutanga, yakashambidzwa uye yozobatwa ne hydrofluoric acid, inobatwa pakupisa kwemaawa 2-3, uye yozocheneswa nekucheneswa Izvo zvisina kuchena uye oxides pamusoro pejecha requartz zvinogona kubviswa zvinobudirira, uye kuchena uye kunaka kwejecha requartz rinogona kuvandudzwa.
FOCS Fiber corrosion
Hydrofluoric acid inozadza corrosion ye photonic crystal fiber (PCF) yakagadzirwa.Hydrofluoric acid yakazadzwa mugomba remhepo redrawn photonic crystal fiber.Nekushandura chimiro chayo chemuchinjiko, iyo photonic crystal fiber ine chimiro chakasarudzika yakagadziridzwa kuti ichinje yayo mwenje conductivity.Mhedzisiro yacho inoratidza kuti kurasikirwa kwekudonha uye kurasikirwa kwekuparadzira kuderera neiyo corrosion degree yegomba remhepo yephotonic crystal fiber, iyo nonlinear coefficient inowedzera zviri pachena, iyo inoshanda refractive index yeiyo core mode uye yakaenzana refractive index ye cladding inoderera zvinoenderana, uye yeboka velocity dispersion inoshandukawo.
ELECTRONIC GRADE
TPT-LCD kutetepa skrini
Pasi pekuchengetedzwa kwephotoresist uye muganhu glue, iyo hydrofluoric acid inogadziriswa, imwe chiyero che nitric acid, concentrated sulfuric acid uye hydrochloric acid inowedzerwa, uye iyo ultrasonic aixiliary mamiriro akawedzerwa, chiyero chekucheka chiri pachena chakavandudzwa.Kushata kwepamusoro kunonyatso kuderedzwa nekuchinjanisa nzira dzekuchenesa, uye kunaya kwezvinamatidzwa zvemuchena kunoderedzwa.Gadzirisa dambudziko rekushata kwepamusoro uye chena pamusoro pekunamatira precipitate.
