FAAHFAAHINTA Alaabada
Gaaska fluoride ee Hydrogen wuxuu ku milmaa biyaha, xalkiisa aqueous waxaa loo yaqaanhydrofluoric acid.Badeecadu inta badan waa 35%-50% xal aqueous ah oo gaaska hydrogen fluoride ah, xoogga saarista ugu badan waxay gaari kartaa 75%, waana dareere sigaar cabbin oo aan midab lahayn oo cad.ur daran, kacsan, qiiq cad hawada.Waa awood dhexdhexaad ah inorganic acid, aad u daxalaysa, waxayna baabi'in kartaa dhalooyinka iyo silicates si ay u soo saarto tetrafluoride silikoon gaas ah.Waxa kale oo ay la falgeli kartaa biraha, oksaydhyada birta iyo hydroxides si ay u sameeyaan milix kala duwan, laakiin saameyntu maaha mid u daran sida hydrochloric acid.Dahabka, platinum-ka, rasaasta, paraffin iyo balaastikada qaarkood kuma shaqeeyaan, markaa weelasha waa la samayn karaa.Gaaska fluoride hydrogen waa sahlan tahay in la polymerize, samaynta (HF) 2 (HF) 3 · · Unugyada silsiladda iso-silsiladda, ee xaaladda dareeraha ah, heerka polymerization ayaa kordha.Ku kaydi weelasha ka samaysan rasaasta rasaasta, wax ama balaastiga.Aad bay u sun badan tahay oo boogaha taabashada maqaarka.
ISTICMAALKA wax soo saarka
shahaadadda warshadaha
Habaynta garaafka
Hydrofluoric acid waa asiidh xoog leh oo ka falcelin karta wax kasta oo wasakh ah oo garaafka ku jira, graphite-tuna waxay leedahay iska caabin wanaagsan oo aysiidh ah, gaar ahaan waxay u adkaysan kartaa hydrofluoric acid, taas oo go'aamisa in graphite lagu sifeyn karo hydrofluoric acid.Habka ugu muhiimsan ee habka hydrofluoric acid waa isku dhafka graphite iyo hydrofluoric acid, iyo falcelinta hydrofluoric acid iyo wasakhda muddo wakhti ah si ay u soo saaraan walxaha milmay ama kacsan, ka dib marka la dhaqo si looga saaro wasakhda, fuuqbaxa iyo qalajinta si loo helo graphite la nadiifiyey.
Dhul naadir ah ayaa loo huray
Diyaarinta foloraydhka naadirka ah ee dhulka anhydrouska ah waa roobka fluoride dhulka naadirka ah ee fuuq-baxsan ee ka yimaadda dareeraha aqueous, ka dibna fuuq-baxa, ama fluorine toos ah oo ah okssaydh dhuleed naadir ah oo leh wakiilada fluorine.Solubility of fluoride naadirka ah waa mid aad u yar, iyo isticmaalka hydrofluoric acid ka soo daadi kara ka hydrochloric acid, sulfuric acid ama nitric acid xal dhul dhif ah (soo-daadku waa qaab of fluoride fuuqeeyay).
Daaweynta dusha birta
Ka saar wasakhda oksijiinta ku jirta oogada sare Hydrofluoric acid waa asiidh daciif ah, oo la mid ah xoogga formic acid.Isku-darka guud ee acid hydrofluoric ee ganacsi ahaan la heli karo waa 30% ilaa 50%.Astaamaha ugu muhiimsan ee ka saarista miridhku acid hydrofluoric waa sida soo socota: (1) milmi kara xeryahooda silikoon-ka kooban, aluminium, chromium iyo oxides biraha kale sidoo kale waxay leeyihiin milmay wanaagsan, caadi ahaan loo isticmaalo in lagu xoqo shubo, birta ahama iyo workpieces kale.(2) Birta iyo birta workpieces, hydrofluoric acid diirada hoose waxaa loo isticmaali karaa ka saarida miridhku.Xalka aqueous ee hydrofluoric acid oo leh fiirsashada 70% ayaa saameyn ku yeelanaysa birta (3) Hydrofluoric acid oo leh fiirsashada qiyaastii 10% waxay leedahay daxal daciif ah oo ku saabsan magnesium iyo alloyskeeda, sidaas darteed waxaa badanaa loo isticmaalaa xoqidda shaqada magnesium.(4) Macdanta rasaasta guud ahaan kuma daxaleysato hydrofluoric acid;Nickelku wuxuu leeyahay iska caabin xooggan oo ah xalalka hydrofluoric acid oo leh xaddi ka badan 60%.Hydrofluoric acid aad ayay u sun badan tahay, waana kacsan tahay, marka loo isticmaalo si looga hortago xidhiidhka bini'aadamka ee dareeraha acid hydrofluoric iyo hydrogen fluoride gaaska, haanta etching ayaa sida ugu fiican loo xirxiray oo leh qalab hawo wanaagsan leh, biyaha wasakhda leh ee fluorined waa la sii dayn karaa daaweynta ka dib.
Quartz ciid-qaadista
Waxay si fiican u shaqeysaa marka lagu daaweeyo hydrofluoric acid, laakiin waxay u baahan tahay feejignaan sare.Marka lala wadaago sodium dithionite, uruurinta hoose ee hydrofluoric acid waa la isticmaali karaa.Qayb gaar ah oo ah hydrochloric acid iyo hydrofluoric acid ayaa lagu qasi jiray qulqulka ciidda quartz isku mar iyadoo loo eegayo saamiga;Waxa kale oo lagu daweyn karaa xal hydrochloric acid marka hore, la dhaqo ka dibna lagu daaweeyaa hydrofluoric acid, lagu daaweeyaa heerkul sare 2-3 saacadood, ka dibna la sifeeyo oo la nadiifiyo Wasaqda iyo oksijiinta ee dusha ciidda quartz si fiican ayaa loo saari karaa, iyo nadiifnimada iyo tayada ciidda quartz waa la hagaajin karaa.
Daxalka Fiber ee FOCS
Daxalka buuxinta aashitada Hydrofluoric ee fiber-ka kristal (PCF) ayaa la sameeyay.Hydrofluoric acid ayaa lagu shubay dalool hawo ah oo la sawiray fiber crystal photonic.Iyada oo la beddelayo qaab-dhismeedka qaybta iskutallaabta, fiber-ka crystal photonic oo leh qaab dhismeed gaar ah ayaa la sameeyay si loo beddelo dhaqdhaqaaqa iftiinka.Natiijooyinku waxay muujinayaan in luminta daadinta iyo lumista kala firdhisku ay hoos u dhacdo heerka daxalka ee daloolka hawada ee fiber-ka kristal ee photonic, isku-dhafka aan tooska ahayn ayaa si cad u kordheysa, tusaha wax-ku-oolka ah ee habka xudunta u ah iyo tusaha u dhigma ee xinjirowga ayaa hoos u dhacaya. iyo kala firdhinta xawaaraha kooxdu sidoo kale waa isbedeshaa.
FASALKA ELECTRONICKA
khafiifinta shaashadda TPT-LCD
Iyada oo la ilaalinayo xabagta sawir-qaadista iyo xabagta xudduudaha, diiradda hydrofluoric acid waa la hagaajiyaa, qadar gaar ah oo nitric acid ah, sulfuric acid iyo hydrochloric acid ayaa lagu daraa, iyo xaaladaha kaaliyaha ultrasonic ayaa lagu daraa, heerka etching ayaa si cad loo hagaajiyay.Qalafsanaanta dusha sare ayaa si wax ku ool ah loo dhimay iyadoo la beddelayo hababka nadiifinta, iyo roobabka ku dhejinta dusha cad waa la dhimay.Xalliyaan dhibaatada dusha qallafsan iyo ku dheggan oogada cad.
