Cov yam ntxwv ntawm cov khoom
Phosphoric acid yog nruab nrab-muaj zog acid, thiab nws cov crystallization point (khov point) yog 21° C, thaum nws qis dua qhov kub thiab txias, nws yuav precipitate semi-aqueous (ice) crystals. Crystallization yam ntxwv: siab phosphoric acid concentration, siab purity, siab crystallinity.
Phosphoric acid crystallization yog kev hloov ntawm lub cev es tsis yog kev hloov tshuaj. Nws cov khoom siv tshuaj yuav tsis hloov pauv los ntawm crystallization, qhov zoo ntawm phosphoric acid yuav tsis cuam tshuam los ntawm crystallization, tsuav yog qhov kub thiab txias tau muab rau yaj lossis dej kub dilution, nws tseem tuaj yeem siv tau ib txwm.
Khoom siv
Kev lag luam chiv
Phosphoric acid yog ib qho tseem ceeb ntawm cov khoom nruab nrab hauv kev lag luam chiv, uas yog siv los tsim cov phosphate chiv thiab compound chiv.
Kev lag luam electroplating
Kho cov hlau nto los tsim ib qho insoluble phosphate zaj duab xis ntawm cov hlau nto los tiv thaiv cov hlau los ntawm corrosion. Nws yog tov nrog nitric acid raws li ib tug tshuaj txhuam hniav los txhim kho cov tiav ntawm hlau nto.
Xim thiab xim kev lag luam
Phosphoric acid yog siv los ua cov khoom siv raw rau kev tsim cov phosphate. Phosphates yog siv nyob rau hauv cov xim thiab pigment kev lag luam raws li pigments nrog tshwj xeeb functions. Raws li nplaim taws retardant, xeb tiv thaiv, tiv thaiv corrosion, hluav taws xob tiv thaiv, antibacterial, luminescence thiab lwm yam additives rau hauv txheej.
Siv ua chemical raw khoom
Cov khoom siv raw rau kev tsim ntau yam phosphates thiab phosphate esters siv hauv xab npum, ntxhua khaub ncaws, tshuaj tua kab, phosphorous nplaim hluav taws thiab tshuaj kho dej.
Kev khaws cia thiab kev thauj mus los yam ntxwv
Khaws nyob rau hauv qhov kub thiab txias, qhuav, zoo-ventilated warehouse, kom deb ntawm hluav taws kub thiab cua sov qhov chaw. Khaws lub pob ntim thiab khaws cia cais ntawm alkalis, zaub mov thiab pub.
Xyuas kom meej tias lub ntim ntim tau kaw tag nrho thaum lub sijhawm thauj mus los, thiab nws yog txwv tsis pub thauj khoom nrog zaub mov thiab pub.
