Acid etching yog ua tiav siv hexafluorosilicic acid (H2SiF6) uas, thaum anhydrous, yog xim tsis muaj xim. Cov kua qaub yog npaj los ntawm dissolving silica nyob rau hauv ib tug sib tov ntawm hydroelectric acid ( hydrochloric acid ), quartz hmoov, calcium fluoride , thiab concentrated sulfuric acid muab tau tom qab cua sov.
Tsis tas li ntawd, vim li cas HF siv rau etching iav?
Hydrofluoric acid yog ib qho kev daws teeb meem ntawm hydrogen fluoride ( HF ) hauv dej. Kev daws teeb meem ntawm HF yog colourless, acidic thiab corrosive heev. Nws yog feem ntau siv rau iav etch thiab silicon wafers. Thaum twg hydrofluoric acid los rau hauv kev sib cuag nrog tib neeg daim tawv nqaij nws ua rau sib sib zog nqus burns.
Ib yam li ntawd, yog dab tsi hauv iav etching cream? iav etching cream kuj dav paub tias yog acid cream thiab yog ib txoj hauv kev yooj yim tshaj plaws los kho koj tus kheej iav . Cov khoom sib xyaw ua ke muaj cov tshuaj lom neeg muaj kev phom sij: Barium Sulfate, Sulfuric Acid, Sodium Bifluoride, thiab Ammonium Bifluoride.
Yog li ntawd, puas hydrochloric acid etch iav?
Boiling lub iav hauv 36% hydrochloric acid Kev daws rau 30 min tau zoo dua hauv kev txo cov sodium, calcium, thiab aluminium atoms ntawm qhov chaw iav tshaj lwm yam etching txoj kev siv hydrochloric acid . Qhov tob uas raug cuam tshuam los ntawm tshuaj lom neeg etching nrog hydrochloric acid ua 70nm.
Dab tsi yog lub ntiaj teb muaj zog acid?
Carborane superacids tuaj yeem suav hais tias yog lub ntiaj teb muaj zog tshaj plaws solo kua qaub Raws li fluoroantimonic kua qaub Qhov tseeb yog qhov sib xyaw ntawm hydrofluoric kua qaub thiab antimony pentafluoride.

Dab tsi yog cov cim kev phom sij ntawm cov kua qaub los nag ntawm cov dej hauv dej?
Lus Nug: Cov cim qhia phom sij ntawm cov kua qaub los ntawm cov dej hauv lub cev yog dab tsi? Teb: Qee cov cim qhia suav nrog qhov nce hauv pH ntawm cov dej, cov nroj tsuag tuag lossis tuag, tsis muaj ntses / ntses tuag ntab, thiab tsis hnov tsw ntawm cov qe lwj (sulfur)
Dab tsi yog cov tshuaj tiv thaiv ntawm daim ntawv xiav litmus thaum dipped rau hauv cov kua qaub uas muaj tshuaj?
Daim ntawv liab litmus reacts rau alkaline tshuaj los ntawm tig xiav, thaum xiav litmus ntawv reacts rau acidic tshuaj los ntawm tig liab
Cov khoom siv hauv tsev twg muaj cov iav?
Gears tuaj yeem ua rau cov khoom txav mus rau qhov sib txawv, nrawm dua lossis qeeb. Piv txwv ntawm cov khoom siv nrog lub zog yog cov moos tsis yog digital, tsheb, xyaum, phau ntawv tuaj yeem qhib thiab tsheb kauj vab. Lwm qhov kev siv rau lub zog yog ' nthuav dav lub cev txwv ntawm tib neeg lub cev.' Cov rooj zaum muaj zog thiab cov nqa nqa muaj zog
Dab tsi yog cov cuab yeej lossis cov txheej txheem siv los hloov cov ntaub ntawv kev ua haujlwm rau hauv cov ntaub ntawv kev ua haujlwm hauv cov txheej txheem tswj Scope?
Variance Analysis yog ib qho cuab yeej & Cov txheej txheem ntawm Kev Tswj Scope Txheej Txheem thiab Kev Ntsuas Kev Ua Haujlwm Ua Haujlwm (WPM) yog qhov tso tawm ntawm cov txheej txheem no
Lub zog twg hauv qab no feem ntau yog lub luag haujlwm rau cov kua qaub nag hauv Northeast United States?
Lub hauv paus emissions lub luag hauj lwm rau acid deposition yog sulfur dioxide (SO2) thiab oxides ntawm nitrogen (NOx) los ntawm combustion ntawm thee, roj thiab natural gas
