Phosphoric Acid: Khoom, Siv, thiab Kev Nyab Xeeb

Phosphoric acidyog cov ntxhia acid nrog cov tshuaj formula H3PO4. Nws yog cov kua ntshiab, tsis muaj xim uas muaj ntxhiab tsw thiab soluble hauv dej. Cov kua qaub no yog muab los ntawm cov ntxhia phosphorus, thiab feem ntau yog siv rau ntau yam kev lag luam thiab cov neeg siv khoom.

Ib qho tseem ceeb ntawm kev siv phosphoric acid yog nyob rau hauv zus tau tej cov chiv. Nws yog ib qho tseem ceeb hauv kev tsim cov phosphate chiv, uas yog qhov tseem ceeb rau kev txhawb nqa cov nroj tsuag noj qab haus huv thiab nce qoob loo. Tsis tas li ntawd, phosphoric acid yog siv nyob rau hauv cov khoom noj thiab dej haus kev lag luam raws li ib tug additive rau acidify thiab tsw ntau yam khoom, xws li dej qab zib thiab jams.

Ntxiv nrog rau nws txoj kev ua liaj ua teb thiab khoom noj khoom haus, phosphoric acid kuj tseem siv rau hauv kev tsim cov tshuaj detergents, kho hlau, thiab tshuaj kho dej. Nws muaj nuj nqis rau nws lub peev xwm tshem tawm xeb thiab nplai los ntawm cov hlau nto, ua rau nws yog ib qho tseem ceeb hauv cov khoom siv tu tsev.

Thaum phosphoric acid muaj ntau daim ntawv thov kev lag luam, nws yog ib qho tseem ceeb uas yuav tsum tau ua tib zoo saib xyuas vim nws qhov xwm txheej corrosive. Kev sib cuag ncaj qha rau ntawm daim tawv nqaij lossis ob lub qhov muag tuaj yeem ua rau khaus thiab kub hnyiab, yog li kev tiv thaiv kev nyab xeeb kom zoo, xws li hnav khaub ncaws tiv thaiv thiab tsom iav, yuav tsum tau noj thaum ua haujlwm nrog cov kua qaub no.

Tsis tas li ntawd, kev pov tseg ntawm phosphoric acid yuav tsum tau tswj xyuas lub luag haujlwm kom tsis txhob muaj kev sib kis ntawm ib puag ncig. Dilution thiab neutralization yog ib txoj hauv kev rau kev nyab xeeb pov tseg ntawm phosphoric acid pov tseg.

Hauv kev xaus, phosphoric acid yog ntau yam tshuaj sib xyaw nrog ntau yam kev siv hauv kev ua liaj ua teb, khoom noj khoom haus, thiab kev lag luam. Nws cov khoom ua rau nws yog ib qho tseem ceeb hauv ntau yam khoom siv hauv lub neej txhua hnub. Txawm li cas los xij, nws yog ib qho tseem ceeb los tswj thiab pov tseg cov phosphoric acid kom muaj kev nyab xeeb thiab ib puag ncig lub luag haujlwm kom txo qis kev pheej hmoo thiab kev phom sij.
