Phosphoric acid feem ntau yog siv rau hauv kev lag luam tshuaj, zaub mov, chiv thiab lwm yam lag luam, suav nrog cov tshuaj tiv thaiv xeb, khoom noj khoom haus, kho hniav thiab orthopedic, EDIC corrosive, electrolyte, flux, dispersant, industrial corrosive, chiv, raw khoom thiab cov khoom siv tu tsev. cov khoom. Kuj tseem siv los ua tshuaj reagent, phosphate yog ib qho khoom noj rau txhua hom kev ua neej.
Phosphoric acid los yog orthophosphoric acid, nrog ib qho hnyav molecular ntawm 97.994, yog ib hom inorganic acid thiab yog ib qho muaj zog acid. Nws tuaj yeem tau txais los ntawm kev ua kom phosphorus pentoxide hauv dej kub. Orthophosphoric acid yog tau los ntawm kev kho apatite nrog sulfuric acid hauv kev lag luam. Phosphoric acid yog yooj yim deliquescent nyob rau hauv cov huab cua. Cov cua sov yuav poob dej kom tau txais pyrophosphoric acid, thiab tom qab ntawd poob dej ntxiv kom tau txais metaphosphoric acid.
Cov ntaub ntawv txuas ntxiv:
Kev siv thaj chaw:
1. Kev ua liaj ua teb: Phosphoric acid yog cov khoom siv raw rau kev tsim cov phosphate chiv tseem ceeb (superphosphate, potassium dihydrogen phosphate, thiab lwm yam), thiab tseem yog cov khoom siv raw rau kev tsim cov khoom noj pub mis (calcium dihydrogen phosphate).
2. Kev lag luam: Phosphoric acid yog ib qho tseem ceeb tshuaj raw khoom. Nws lub luag haujlwm tseem ceeb yog raws li hauv qab no:
(1) Kho cov hlau nto kom tsim tau ib zaj duab xis phosphate insoluble ntawm cov hlau nto los tiv thaiv cov hlau los ntawm corrosion.
(2) Sib xyaw nrog nitric acid ua cov tshuaj txhuam hniav los txhim kho qhov smoothness ntawm cov hlau nto.
(3) Phosphate esters, raw khoom rau kev tsim cov tshuaj detergents thiab tshuaj tua kab.
(4) Cov khoom siv raw rau kev tsim cov phosphorus-muaj cov nplaim hluav taws.
3. Khoom noj khoom haus: Phosphoric acid yog ib qho ntawm cov khoom noj ntxiv. Nws yog siv los ua cov kua qaub thiab cov poov xab hauv cov zaub mov, thiab Coke muaj phosphoric acid. Phosphate kuj yog ib qho khoom noj khoom haus tseem ceeb thiab tuaj yeem siv los ua zaub mov noj.
4. Tshuaj: Phosphoric acid tuaj yeem siv los npaj cov tshuaj uas muaj phosphorus, xws li sodium glycerophosphate.
