Nyob rau hauv ib txwm muaj xwm txheej, nitric acid yog cov kua tsis muaj xim thiab pob tshab nrog rau qhov ua tsis taus pa thiab khaus khaus.Nws yog ib qho muaj zog oxidizing thiab corrosive monobasic inorganic muaj zog acid.Nws yog ib qho ntawm rau qhov loj inorganic muaj zog acids thiab ib qho tseem ceeb tshuaj raw khoom.Cov tshuaj formula yog HNO3, qhov hnyav molecular yog 63.01, thiab nws yog miscible nrog dej.
Nitric acid muaj ntau yam kev siv, feem ntau yog siv tshuaj chiv, dyes, tiv thaiv lub teb chaws, explosives, metallurgy, tshuaj thiab lwm yam lag luam.
1. Nitric acid yog ib qho tseem ceeb ntawm cov khoom siv raw, feem ntau yog siv rau kev tsim cov chiv xws li ammonium nitrate, calcium ammonium nitrate, nitrophosphate fertilizer, thiab nitrogen, phosphorus thiab potassium.
2. Nws yog siv los ua etchant thiab muaj zog acid tu etchant, thiab tuaj yeem siv ua ke nrog glacial acetic acid, hydrogen peroxide, thiab lwm yam.
3. Nitric acid tuaj yeem siv los ua tus neeg saib xyuas thiab derusting rau cov khoom siv carbon steel thiab stainless hlau, siv rau hauv redox kho cov dej phwj tuaj thiab cov dej khib nyiab;nyob rau hauv kev kho mob lom ntawm cov dej phwj tuaj, nws tuaj yeem siv los ua cov nitrogen hauv cov khoom noj microbial, thiab lwm yam.
4. Kev lag luam coatings yog siv los tsim nitro varnishes thiab nitro enamels
5. Nitric acid tau siv ntau hom los ua cov khoom siv rau cov kua roj foob pob hluav taws
6. Nitric acid kuj yog ib qho tseem ceeb thiab tseem ceeb analytical chemical reagent, xws li cov kuab tshuaj thiab oxidant.Nws kuj yog siv rau hauv cov organic synthesis los npaj ntau yam nitro tebchaw.
txoj kev cia
Khaws rau hauv ib qho chaw txias, ventilated warehouse.Khaws kom deb ntawm qhov hluav taws kub thiab qhov chaw kub.Qhov ntsuas kub yuav tsum tsis pub tshaj 30 ℃, thiab cov av noo ntawm cov txheeb ze yuav tsum tsis pub tshaj 80%.Khaws lub thawv kaw kom nruj.Nws yuav tsum tau muab cais los ntawm kev txo cov neeg ua haujlwm, alkalis, cawv, alkali hlau, thiab lwm yam, thiab yuav tsum tsis txhob sib xyaw.
Kaw ua haujlwm, xyuam xim rau qhov cua.Kev khiav hauj lwm yog mechanized thiab automated li sai tau.Cov neeg ua haujlwm yuav tsum tau txais kev cob qhia tshwj xeeb thiab ua raws li cov txheej txheem ua haujlwm.
