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
Fosfooraska, oo sidoo kale loo yaqaan 'orthophosphoric acid', waa asiidh jireed oo caadi ah. Waa aashito dhexdhexaad ah oo xoog leh oo leh caanaha kiimikada H3PO4 iyo miisaanka kelli ee 97.995. Ma degenaansho, ma fududa in la dumiyo, ku dhawaad ma jiro oksaydhyo.
Phosphoric acid waxaa inta badan loo isticmaalaa daawooyinka, cuntada, bacriminta iyo warshadaha kale, oo ay ku jiraan sida inhibitors miridhku, cuntada lagu daro, ilkaha iyo qalliinka lafaha, caustics EDIC, electrolytes, qulqulka, kala firdhiyey, caustics warshadaha, Bacriminta sida alaabta ceeriin iyo qaybaha alaabta nadiifinta guriga. , waxaana sidoo kale loo isticmaali karaa sida walxaha kiimikaad.
Beeraha: Phosphoric acid waa walxo ceeriin ah oo loogu talagalay soo saarista bacrimiyeyaasha fosfooraska muhiimka ah (calcium superphosphate, potassium dihydrogen phosphate, iwm.), iyo sidoo kale soo saarista nafaqooyinka quudinta (calcium dihydrogen phosphate).
Warshadaha: Phosphoric acid waa walxo kiimiko ah oo ceeriin ah oo muhiim ah. Shaqadeeda ugu muhiimsan waa sida soo socota:
1, daawaynta dusha birta, samaynta filimka fosfooraska ee aan la milmi karin ee dusha birta ah, si looga ilaaliyo birta daxalka.
2, lagu qaso nitric acid sida kiimikaad polishing, si loo hagaajiyo dhamaystirka dusha birta.
3, wax soo saarka sahayda dhaqida, sunta cayayaanka ee alaabta ceeriin phosphate ester.
4, wax soo saarka alaabta ceeriin oo ay ku jiraan fosfooraska ololka retardant.
Cuntada: phosphoric acid waa mid ka mid ah cuntada lagu daro, cuntada sida wakiilka dhanaan, wakiilka nafaqeynta khamiirka, koolada waxaa ku jira fosfooraska acid. Phosphates sidoo kale waa cunto lagu daro oo muhiim ah waxaana loo isticmaali karaa kobciyayaal nafaqo.
Daawo: Phosphoric acid waxaa loo isticmaali karaa in lagu sameeyo dawooyinka fosfooraska, sida sodium glycerophosphate.
