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
Phosphoric acid ama orthophosphoric acid, formula kiimikaad H3PO4, miisaanka kelli 97.9724, waa aashitada inorganic caadiga ah, waa aashitada dhexdhexaad ah oo xooggan. Waxaa lagu helaa iyadoo lagu milmo fosfooraska tetroxide ee biyaha kulul. Orthophosphoric acid waxaa lagu helaa ganacsi ahaan iyadoo lagu daweynayo apatite leh sulfuric acid. Fosfooraska aashitada ayaa si fudud u fuuqbaxa hawada. Kuleylku wuxuu lumiyaa biyaha pyrophosphoric acid, waxayna sii luminaysaa biyaha metaphosphate. Phosphoric acid waxaa inta badan loo isticmaalaa dawooyinka, cuntada, bacriminta iyo warshadaha kale, waxaana sidoo kale loo isticmaali karaa sida reagent kiimikaad.
Qaab dhismeedka walxaha
Orthophosphate waa phosphoric acid oo ka kooban hal fosfo-oxygen tetrahedron. Unugyada phosphoric acid molecule, P atom waa sp3 hybridized, saddex orbitals hybrid waxay sameeyaan seddex sigma bonds oo leh atamka oksijiinta, kan kale ee P - O wuxuu ka kooban yahay hal bond sigma oo fosfooraska ilaa oksijiin iyo laba d-pπ bond oo ka socda ogsijiin ilaa fosfooraska. Xidhiidhka sigma waxa samaysma isuduwidda lammaane keli ah oo elektaroonig ah oo ka imanaya atamka fosfooraska ilaa wareega bannaan ee atamka oksijiinta. d←p bond waxa uu ku dhisan yahay isku-xidhka py iyo pz atamka oksijiinta oo ay la socdaan dxz iyo dyz wareegyada banaan ee atamka fosfooraska. Maaddaama tamarta 3d ee atamka fosfooraska ay aad uga badan tahay tamarta 2p ee atamka oksijiinta, orbitals molecular ma aha mid aad waxtar u leh, sidaas awgeed PO bonds waa saddex laablaab xagga tirada, laakiin dhexdhexaad ah oo u dhexeeya hal iyo labalaab bond marka la eego tamarta curaarta. iyo dhererka curaarta. Joogitaanka curaarta hydrogen ee labadaba H3PO4 saafi ah iyo hydrateskeeda crystalline ayaa laga yaabaa inay xisaabiso viscosity ee xalka fosfooraska.
Goobta codsiga
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:
Ku daawee dusha birta si aad u abuurto filim fosfooreed aan milmi karin oogada birta si aad birta uga ilaaliso daxalka.
Loo isticmaalo sidii kiimiko kiimiko ah oo lagu qasay nitric acid si loo hagaajiyo dhamaystirka meelaha birta ah.
Soo saarista saabuunta, sunta cayayaanka ee alaabta ceeriin ee phosphate ester.
Walxaha ceeriin ee soo saarida ololka fosfooraska.
Cuntada: Phosphoric acid waa mid ka mid ah cuntada lagu daro, cuntada sida wakiilka dhadhan dhanaan, wakiilka nafaqeynta khamiirka, Coca-Cola 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.
