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

tyuyituyNoocyo badan oo waxqabadyada wax-soo-saarka ee bini'aadamka, waxaa jira fosfooraska, sida cuntada, warshadaha, bacriminta, polishing, iwm. Tani waa goob aad u qani ah codsiga, iyo codsi kasta oo ku yaal field acid.

Si kastaba ha ahaatee, marar dhif ah ayaynu ku xusnaa magacyada fosfatetada nolosheena. Dhinaca kale, sababtoo ah phosphate maaha walax aan la xiriiri doono nolosheena, waxayna ku badan tahay farsamaynta, wax soo saarka, iyo wax soo saarka.

Dhanka kale, waa sababtoo ah fosfooraska badan oo acid ah, mid ka mid ah qaybaha alaabta qaarkood ayaa ka muuqda baakadaha ama buug-tilmaameedka, celceliska qofka ma bixin doono taxadar gaar ah kuwan.

Haddaba maanta waan kaala hadli doonnaa. Waxay u muuqataa in fosfooraska "aan la arki karin" nolosheena ay dhab ahaantii waxtar leedahay:

1. Warshadaha dawooyinka, waxa loo isticmaali karaa in lagu sameeyo fosfooraska birta, iwm.

2. Waxaad isticmaali kartaa nafaqeynta khamiirka ama walxaha acidic ah sida koolada, biirka, nacnaca, saliidda midabaynta, waxyaabaha caanaha laga sameeyo, cabitaannada, iwm ee warshadaha cuntada;

3. Waxaa loo isticmaali karaa in lagu soo saaro sibidhka refractory. Sibidhkani wuxuu kordhin karaa nolosha adeegga birta sifayaasha ilaa xad;

4. Isticmaalka kiimiko u gaar ah waxay noqon kartaa rinjiga miridhku biraha ee warshadaha daahan si loo yareeyo khasaaraha alaabta;

5. Waxaa loo isticmaali karaa in lagu habeeyo nadiifiyaha. Nadiifiyahani wuxuu si gaar ah ugu habboon yahay in laga saaro wasakhooyinka ka soo muuqan doona nooca daabacaadda ee warshadaha daabacaadda;

6. Waxaad nadiifin kartaa alaabada aluminium sababtoo ah waxaa loo isticmaali karaa in lagu habeeyo kiimikooyinka iyo dareeraha polishing electrolytic si loo sameeyo fosfooraska meelaha birta ah;

7. Marka saxarka caagga ah loo baahan yahay inta lagu jiro habka wax soo saarka, waxaa loo isticmaali karaa sida alaabta ceeriin ee xinjirowga iyo xirmooyinka aan noolaha ahayn;

8. Sidoo kale waa ujeeddada ugu badan ee innaga jirta, taas oo ah in aan u isticmaalno si loo soo saaro bacriminta fosfooraska ee xoogga leh iyo bacriminta isku dhafan.

Intaa waxaa dheer, waxaa jira fosfooraska heerka daroogada ah oo loo isticmaali karo wax soo saarka daawada, fosfooraska polymer ee wax soo saarka polyphosphoos, alaabta ceeriin organic synthetic, iwm. Kuwani waa dhammaan codsiyada fosfooraska.
