Waikawa Phosphoric

whakaahuatanga poto:

Ko te waikawa pararopi noa, ko te waikawa phosphoric ehara i te mea ngawari ki te whakaheke, ehara i te mea ngawari ki te pirau, tata karekau he waikura, me te waikawa noa, he waikawa ngoikore ternary, he ngoikore ake tona waikawa i te waikawa puota, waikawa pungatara, waikawa nitric, engari he kaha ake i te acetic. te waikawa, te waikawa boric, me etahi atu. Ko te waikawa Phosphoric ka ngawari ki te whakakore i te hau, ka ngaro te wai o te wera ki te tiki waikawa pyrophosphoric, katahi ka ngaro te wai hei tiki metaphosphate.

Whakamahi Hua

Te whakamahi matua

Ahuwhenua:Ko te waikawa Phosphoric he rauemi mata mo te hanga i nga maniua phosphate nui (superphosphate, potassium dihydrogen phosphate, me etahi atu), he mea ano hoki hei hanga i nga matūkai kai (calcium dihydrogen phosphate).

Ahumahi:Ko te waikawa Phosphoric he rawa matū nui.Ko ona mahi matua e whai ake nei:

1, hamani i te mata whakarewa, whakaputa kiriata phosphate insoluble i runga i te mata whakarewa ki te tiaki i te whakarewa i te waikura.

2, i konatunatua ki te waikawa nitric hei whakakoi matū hei whakapai ake i te mutunga o te mata whakarewa.

3, te hanga o te horoi kai, pesticide raw rauemi phosphate hākawa.

4, te hanga o te ūkuikui-kei roto mura ahi retardant rauemi raw.

Kai:Ko te waikawa Phosphoric tetahi o nga taapiri kai, i roto i te kai hei kaihoko kawa, te kai rewena, kei te cola te waikawa phosphoric.Ko te Phosphate he taapiri kai nui, ka taea te whakamahi hei whakakaha matūkai.

Rongoā:Ka taea te whakamahi i te waikawa Phosphoric ki te hanga i nga raau taero whai ūkuikui, penei i te konutai glycerophosphate.
