Lead nitrate txoj kev ua tau zoo tau sib tham ntev hauv ntau qhov kev lag luam, suav nrog kev kho mob, kev siv hauv kev lag luam, thiab txawm tias nyob hauv thaj chaw ntawm pyrotechnics.Raws li tus neeg sawv cev muaj zog oxidizing, txhuas nitrate tau txais txiaj ntsig vim nws muaj peev xwm ua rau muaj ntau yam tshuaj lom neeg.Hauv tsab xov xwm no, peb yuav tshawb txog qhov ua tau zoo ntawm cov hlau lead nitrate hauv ntau qhov chaw thiab sib tham txog nws cov txiaj ntsig thiab kev pheej hmoo.
Hauv kev kho mob, txhuas nitrate tau pom nws daim ntawv thov raws li kev kho mob rau qee yam mob.Nws tau paub tias yuav ua tau zoo hauv kev kho mob ntawm daim tawv nqaij xws li pob kws thiab pob kws.Thaum siv tshuaj pleev ib ce, txhuas nitrate reacts nrog cov proteins hauv daim tawv nqaij, ua rau lawv denature.Qhov no ua rau kev puas tsuaj ntawm cov ntaub so ntswg, ua rau tshem tawm cov pob kws thiab pob kws.Txawm li cas los xij, nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias txhuas nitrate yuav tsum tsuas yog siv raws li kev taw qhia ntawm tus kws kho mob vim nws muaj peev xwm toxicity.
Hauv cov ntawv thov kev lag luam, txhuas nitrate tau pom tias muaj txiaj ntsig zoo li cov tshuaj tiv thaiv corrosion.Nws yog feem ntau siv rau hauv cov txheej txheem hlau plating los tiv thaiv kev tsim cov xeb thiab lwm yam corrosion.Lead nitrate tsim cov txheej txheem tiv thaiv ntawm cov hlau, tiv thaiv kev sib cuam tshuam ntawm cov khoom corrosive nrog cov khoom siv hauv qab.Qhov no tau ua pov thawj tseem ceeb hauv kev ua kom lub neej ntev ntawm cov qauv hlau thiab cov tshuab, tshwj xeeb tshaj yog nyob rau hauv ib puag ncig corrosive.
Sib nrug los ntawm nws cov ntawv thov hauv tshuaj thiab kev lag luam, txhuas nitrate plays lub luag haujlwm tseem ceeb hauv thaj chaw pyrotechnics.Nws yog ib qho tseem ceeb hauv kev tsim cov nplaim taws thiab cov foob pob hluav taws, qhov uas nws ua raws li tus neeg sawv cev oxidizing.Thaum ignited, txhuas nitrate decomposes, tso oxygen thiab pab txoj kev combustion.Qhov no ua rau cov xim ci thiab dazzling cov duab uas yog cov yam ntxwv ntawm pyrotechnics.Kev ua tau zoo ntawm cov hlau lead nitrate hauv daim ntawv thov no nyob hauv nws lub peev xwm los tsim cov xim zoo ib yam thiab zoo nkauj.
Thaum txhuas nitrate qhia tau hais tias ua tau zoo hauv ntau qhov kev lag luam, nws yog ib qho tseem ceeb kom paub txog cov kev pheej hmoo uas cuam tshuam nrog nws txoj kev siv.Lead yog ib yam tshuaj lom thiab, yog tias noj los yog nqus tau, tuaj yeem ua rau mob hnyav.Kev cuam tshuam rau cov hlau lead tuaj yeem ua rau muaj kev puas tsuaj rau lub paj hlwb, teeb meem kev loj hlob ntawm cov menyuam yaus, thiab lwm yam teebmeem kev noj qab haus huv.Yog li, kev ntsuas kev nyab xeeb nruj yuav tsum tau ua thaum tuav thiab siv lead nitrate.
Tsis tas li ntawd, kev pov tseg ntawm cov hlau lead nitrate pov tseg yuav tsum tau txiav txim siab tshwj xeeb vim nws cov tshuaj lom.Kev pov tseg tsis raug tuaj yeem ua rau ib puag ncig muaj kuab paug, paug cov dej thiab av.Nws yog ib qho tseem ceeb rau kev lag luam thiab cov tib neeg kom ua raws li cov lus qhia thiab cov kev cai kom muaj kev nyab xeeb ntawm cov khoom siv lead ua nitrate.
Hauv kev xaus, txhuas nitrate qhia tau hais tias ua tau zoo hauv ntau daim ntawv thov, xws li kev kho mob mus rau cov txheej txheem kev lag luam thiab pyrotechnics.Nws lub peev xwm los ua cov tshuaj tiv thaiv thiab ua raws li tus neeg sawv cev oxidizing ua rau nws muaj txiaj ntsig hauv cov haujlwm no.Txawm li cas los xij, nws cov tshuaj toxicity xav tau ceev faj tuav thiab pov tseg kom zoo kom tsis txhob muaj kev phom sij rau kev noj qab haus huv thiab kev ua qias tuaj ib puag ncig.Raws li nrog rau txhua yam tshuaj, nws yog ib qho tseem ceeb los ntsuas qhov txiaj ntsig thiab kev pheej hmoo ua ntej siv lead nitrate.
