Isticmaal:
Isticmaalka beeraha:Waxyaabaha ceeriin ee bacriminta fosfatetada iyo quudinta nafaqooyinka
Isticmaalka warshadaha: alaabta ceeriin kiimikaad
1.Birta ka ilaali daxalka
2. Isku darka nitric acid sida wakiilka polishing kiimikada si loo hagaajiyo dhamaadka dusha birta
3.Waxyaabaha phosphatide ee loo isticmaalo soo saarista alaabta lagu dhaqo iyo cayayaanka
4.Wax soo saarka fosfooraska ka kooban walxaha flameretardant.
Cuntooyinka lagu daro waxay isticmaalaan: dhadhanka aysidhka, Nafaqada khamiirka,, sida kookaha.
Isticmaalka caafimaad: si loo soo saaro dawo ka kooban fosfooraska, sida Na 2 Glycerophosphat
1, phosphoric acid waa alaabta ceeriin ee soo saarista bacriminta fosfooraska muhiimka ah (superphosphate, potassium dihydrogen phosphate, iwm.), iyo sidoo kale alaabta ceeriin ee wax soo saarka nafaqooyinka quudinta (calcium dihydrogen phosphate).
2, daawee dusha birta, soo saar filim fosfateed aan milmi karin oogada birta si ay birta uga ilaaliso daxalka.
3, lagu qaso nitric acid sida polishing kiimikaad si loo hagaajiyo dhamaadka birta.
4, wax soo saarka sahayda dhaqida, sunta cayayaanka ceeriin phosphate ester.
5, wax soo saarka fosfooraska ka kooban alaabta ceeriin ee ololka.
6, phosphoric acid waa mid ka mid ah cuntada lagu daro, cuntada sida wakiilka dhanaan, nafaqada khamiirka, Cola ka kooban fosfooraska acid. Phosphate sidoo kale waa cunto lagu daro muhiim ah waxaana loo isticmaali karaa kobciye nafaqo.
7, phosphoric acid waxaa loo isticmaali karaa in lagu sameeyo daawooyinka fosfooraska ku jira, sida sodium glycerophosphate.
