Phosphoric Acid 85% Rau Kev Ua Liaj Ua Teb

Phosphoric acid, tseem hu ua orthophosphoric acid, yog ib qho inorganic acid feem ntau siv nyob rau hauv ntau yam lag luam. Nws muaj cov acidity me ntsis, nws cov tshuaj formula yog H3PO4, thiab nws qhov hnyav molecular yog 97.995. Tsis zoo li qee cov kua qaub tsis hloov pauv, phosphoric acid ruaj khov thiab tsis tawg yooj yim, ua rau nws muaj kev ntseeg siab rau ntau yam kev siv. Thaum phosphoric acid tsis muaj zog li hydrochloric, sulfuric, lossis nitric acids, nws muaj zog dua li acetic thiab boric acids. Tsis tas li ntawd, cov kua qaub no muaj cov yam ntxwv ntawm cov kua qaub thiab ua haujlwm tsis muaj zog tribasic acid. Nws yog tsim nyog sau cia tias phosphoric acid yog hygroscopic thiab yooj yim nqus dej los ntawm huab cua. Tsis tas li ntawd, nws muaj peev xwm hloov mus rau pyrophosphoric acid thaum rhuab, thiab tom qab poob dej tuaj yeem hloov mus rau metaphosphoric acid.

Kev siv

Lub versatility ntawm phosphoric acid ua rau nws indispensable nyob rau hauv ntau yam industries, tshwj xeeb tshaj yog kws, zaub mov thiab chiv ntau lawm. Hauv kev lag luam tshuaj, nws yog dav siv los ua tus neeg sawv cev tiv thaiv xeb thiab ua cov khoom xyaw hauv cov txheej txheem kho hniav thiab orthopedic. Raws li cov khoom noj ntxiv, nws ua kom cov khoom ruaj khov zoo. Phosphoric acid kuj yog siv los ua ib qho etchant hauv electrochemical impedance spectroscopy (EDIC) thiab ua ib qho electrolyte, flux thiab dispersant hauv ntau yam kev lag luam. Nws cov khoom corrosive ua rau nws yog ib qho khoom siv zoo rau cov tshuab ntxhua khaub ncaws, thaum hauv kev ua liaj ua teb phosphoric acid yog ib qho tseem ceeb ntawm cov chiv. Tsis tas li ntawd, nws yog ib qho tseem ceeb hauv cov khoom siv tu tsev thiab siv los ua tshuaj lom neeg.

Raws li qhov tshwm sim, phosphoric acid yog ib qho tseem ceeb ntawm kev siv ntau yam khoom siv dav siv hauv ntau yam lag luam. Nws qhov ruaj khov thiab tsis muaj zog, ua ke nrog nws cov acidity nruab nrab, ua rau nws xaiv thawj zaug rau ntau daim ntawv thov. Phosphoric acid txoj kev siv ntau yam, los ntawm cov kws kho mob mus rau cov khoom noj khoom haus, los ntawm cov txheej txheem kho hniav mus rau kev tsim cov chiv, ua pov thawj nws qhov tseem ceeb hauv kev tsim khoom thiab lub neej txhua hnub. Txawm hais tias ua ib qho caustic, electrolyte los yog cov khoom siv tu, cov kua qaub no tau ua pov thawj nws cov txiaj ntsig thiab kev ntseeg tau. Nrog nws cov kev siv ntau yam thiab cov khoom muaj txiaj ntsig, phosphoric acid yog ib qho khoom muaj nqis thoob plaws ntau qhov kev lag luam.
