Pengfa Chemical - Kariya yayin amfani da phosphoric acid

      Phosphoric acidInorganic acid ne na kowa tare da dabarar sinadarai H3PO4.Ba sauƙin jujjuyawa ba, ba sauƙin ruɓewa ba, mai sauƙin lalata a cikin iska.Phosphoric acid shine matsakaici-ƙarfi acid tare da crystallization batu na 21 ° C.Lokacin da zafin jiki ya yi ƙasa da wannan zafin jiki, lu'ulu'u na hemihydrate za su yi hazo.Dumama zai rasa ruwa don samun pyrophosphoric acid, sa'an nan kuma ƙara rasa ruwa don samun metaphosphoric acid.Phosphoric acid yana da dukiyar acid, acidity nasa ya fi hydrochloric acid, sulfuric acid, nitric acid, amma ya fi acetic acid, boric acid, da dai sauransu.

amfani:

Magani: Ana iya amfani da phosphoric acid don shirya magunguna masu ɗauke da phosphorus, irin su sodium glycerophosphate.Noma: Phosphoric acid wani muhimmin albarkatun kasa ne don samar da takin mai magani phosphate (superphosphate, potassium dihydrogen phosphate, da sauransu), da kuma samar da abinci mai gina jiki (calcium dihydrogen phosphate);

Abinci: Phosphoric acid yana ɗaya daga cikin abubuwan da ake ƙara abinci.Ana amfani dashi azaman wakili mai tsami da abinci mai yisti a abinci.Coca-Cola ya ƙunshi phosphoric acid.Phosphate kuma yana da mahimmancin kayan abinci kuma ana iya amfani dashi azaman haɓaka abinci mai gina jiki;

Masana'antu: Phosphoric acid wani muhimmin sinadari ne danye, kuma manyan ayyukansa sune kamar haka;

1. Bi da filin karfe don samar da fim din phosphate wanda ba zai iya narkewa a kan karfen karfe don kare karfe daga lalata;

2. Mix tare da nitric acid a matsayin sinadaran polishing wakili don inganta santsi na karfe surface;

3. Phosphate esters, albarkatun kasa don samar da kayan wanka da magungunan kashe qwari;

4. Raw kayan don samar da phosphorus-dauke da harshen wuta retardants;

Kariya yayin amfani da phosphoric acid:

Don kare fata daga phosphoric acid, muna ba da shawarar sanya tufafin kariya na sinadarai irin su takalma, tufafi masu kariya da safar hannu, muna kuma ba da shawarar ku sayi fatun da aka yi da roba na halitta, polyvinyl chloride, robar nitrile, butyl roba ko kayan kariya na neoprene.

Don kare fuska ko idanu daga abubuwa masu ban haushi da lalata, muna ba da shawarar yin amfani da tabarau na aminci don kariyar sinadarai.

Baya ga iskar shaye-shaye gabaɗaya, muna ba da shawarar yin amfani da iskar shaye-shaye na gida don hana haɗarin numfashi yayin amfani da phosphoric acid, dole ne a ɗauki duk matakan da suka dace na muhalli, kuma ana iya buƙatar tururi kai tsaye a waje.
