Shandisa:
Kushandisa zvekurima: mbishi zvinhu zvephosphate fetiraiza uye kudya kunovaka muviri
Indasitiri kushandiswa: makemikari mbishi zvinhu
1.Chengetedza simbi kubva pakuora
2. Yakasanganiswa ne nitric asidhi semakemikari polishing agent kuti ivandudze kupera kwesimbi
3.Material ye phosphatide iyo inoshandiswa kugadzira chigadzirwa chekugeza uye chezvipembenene
4.Kugadzirwa kwe phosphorus ine flameretardant zvinhu.
Zvekuwedzera zvekudya zvinoshandisa: acidic flavour, Yeast Nutri-ents, senge coca-cola.
Kushandiswa kwekurapa: kugadzira mushonga une phos-phorus, senge Na 2 Glycerophosphat
Phosphoric acid, inozivikanwawo se orthophosphoric acid, yakajairika inorganic acid. Iasidhi yepakati-yakasimba ine kemikari formula H3PO4 uye molecular huremu hwe97.995. Haina kushanduka, isiri nyore kuora, inenge isina oxidation.
Phosphoric acid inonyanya kushandiswa mumishonga, chikafu, fetiraiza uye mamwe maindasitiri, anosanganisira se ngura inhibitors, chikafu chekuwedzera, mazino uye orthopedic kuvhiyiwa, EDIC caustics, electrolytes, flux, dispersants, maindasitiri caustics, fetiraiza seyakabikwa uye zvikamu zvemidziyo yekuchenesa imba. , uye inogonawo kushandiswa semakemikari anoshandisa.
Zvekurima: Phosphoric asidhi chinhu mbishi chekugadzirwa kweakakosha phosphate feteraiza (calcium superphosphate, potassium dihydrogen phosphate, nezvimwewo), uye zvakare yekugadzira chikafu chekudya (calcium dihydrogen phosphate).
Indasitiri: Phosphoric asidhi yakakosha kemikari mbishi zvinhu. Mabasa ayo makuru ndeaya anotevera:
1, kurapwa kwesimbi pamusoro, kuumbwa kweinsoluble phosphate firimu pane simbi pamusoro, kuchengetedza simbi kubva mukuora.
2, yakavhenganiswa ne nitric acid sechemikemikari polish, kuvandudza kupera kwesimbi.
3, kugadzirwa kwezvinhu zvekuwachisa, zvipembenene zvakasvibiswa phosphate ester.
4, kugadzirwa kwezvinhu zvakabikwa zvine phosphorus flame retardant.
Chikafu: phosphoric acid ndeimwe yezvikafu zvinowedzera, mune chikafu seyakavava mumiriri, mbiriso yekudya mumiriri, cola ine phosphoric acid. Phosphates inokoshawo zvokudya zvinowedzera uye zvinogona kushandiswa sezvokudya zvinowedzera.
Mushonga: Phosphoric acid inogona kushandiswa kugadzira mishonga yephosphorous, yakadai sesodium glycerophosphate.
