I-Pengfa Chemical - Izilumkiso xa usebenzisa i-phosphoric acid

      Phosphoric acidi-asidi ye-inorganic eqhelekileyo kunye ne-chemical formula H3PO4.Akukho lula ukuguquguquka, akukho lula ukubola, kulula ukuba i-deliquescence emoyeni.Iasidi yePhosphoric yiasidi esomeleleyo ephakathi nendawo enekristali eyi-21°C.Xa iqondo lobushushu lingaphantsi kobu bushushu, iikristale ze-hemihydrate ziya kunyuswa.Ukufudumeza kuya kuphulukana namanzi ukufumana iasidi ye-pyrophosphoric, kwaye emva koko ulahlekelwe ngamanzi ukufumana i-metaphosphoric acid.I-asidi ye-Phosphoric inepropati ye-asidi, i-acidity yayo ibuthathaka kune-hydrochloric acid, i-sulfuric acid, i-nitric acid, kodwa inamandla kune-acetic acid, i-boric acid, njl.

sebenzisa:

Iyeza: I-Phosphoric acid ingasetyenziselwa ukulungiselela iziyobisi ezine-phosphorus, ezifana ne-sodium glycerophosphate.Ezolimo: I-asidi ye-Phosphoric yimathiriyeli ekrwada ebalulekileyo ekuveliseni izichumisi ze-phosphate (i-superphosphate, i-potassium dihydrogen phosphate, njl.), kunye nokuveliswa kwezondlo zokutya (i-calcium dihydrogen phosphate);

Ukutya: I-Phosphoric acid yenye yezongezo zokutya.Isetyenziswe njenge-agent emuncu kunye ne-yeast yesondlo ekutyeni.I-Coca-Cola iqulethe i-asidi ye-phosphoric.I-Phosphate ikwasisongezo sokutya esibalulekileyo kwaye ingasetyenziswa njengesixhasi sesondlo;

Ushishino: Iasidi yePhosphoric yimchiza ebalulekileyo ekrwada, kwaye imisebenzi yayo ephambili yile ilandelayo;

1. Phatha umphezulu wesinyithi ukwenza ifilimu ye-phosphate enganyibilikiyo kwindawo yesinyithi ukukhusela isinyithi kwi-corrosion;

2. Ixutywe ne-nitric acid njenge-agent yokupholisa imichiza ukuphucula ukugudiswa kwendawo yesinyithi;

3. I-Phosphate esters, imathiriyeli ekrwada yokuveliswa kwezicoci kunye nezibulali-zinambuzane;

4. Imathiriyeli ekrwada yemveliso ye-phosphorus-equlethe i-retardants yomlilo;

Imiqathango xa usebenzisa i-phosphoric acid:

Ukukhusela ulusu kwi-asidi ye-phosphoric, sincoma ukugqoka iimpahla zokukhusela iikhemikhali ezifana neebhuthi, iimpahla zokukhusela kunye neiglavu, sincoma ukuba uthenge izikhumba ezenziwe ngerubha yendalo, i-polyvinyl chloride, i-rubber ye-nitrile, i-rubber ye-butyl okanye i-neoprene gear yokukhusela.

Ukukhusela ubuso okanye amehlo kwizinto ezicasulayo kunye ne-corrosion, sincoma ukuba kusetyenziswe izibuko ezikhuselekileyo zokukhusela iikhemikhali.

Ukongeza kwi-exhaust ventilation, sincoma ukusetyenziswa kwe-ventilation yendawo yokukhupha umoya ukukhusela imingcipheko yokuphefumla xa usebenzisa i-phosphoric acid, zonke izilumkiso eziyimfuneko zokusingqongileyo kufuneka zithathwe, kwaye umsi unokufuna ukukhupha ngaphandle ngokuthe ngqo ngaphandle.
