Pengfa Chemical - Kusamala mukamagwiritsa ntchito phosphoric acid

      Phosphoric acidndi asidi wamba wokhala ndi chilinganizo chamankhwala H3PO4.Osati zosavuta volatilize, zosavuta kuwola, zosavuta deliquescence mu mlengalenga.Phosphoric acid ndi asidi apakati-amphamvu kwambiri ndipo amapaka crystallization point 21°C.Kutentha kukakhala kocheperako kuposa kutentha uku, makhiristo a hemihydrate amapangidwa.Kutentha kumataya madzi kuti mupeze pyrophosphoric acid, kenako ndikutaya madzi kuti mupeze metaphosphoric acid.Phosphoric acid ali ndi katundu wa asidi, acidity yake ndi yofooka kuposa hydrochloric acid, sulfuric acid, nitric acid, koma yamphamvu kuposa asidi acetic, boric acid, etc.

gwiritsani ntchito:

Mankhwala: Phosphoric acid angagwiritsidwe ntchito pokonzekera mankhwala okhala ndi phosphorous, monga sodium glycerophosphate.Ulimi: Phosphoric acid ndi yofunika kwambiri popanga feteleza wa phosphate (superphosphate, potassium dihydrogen phosphate, etc.), komanso kupanga zakudya zopatsa thanzi (calcium dihydrogen phosphate);

Chakudya: Phosphoric acid ndi chimodzi mwazowonjezera pazakudya.Amagwiritsidwa ntchito ngati wowawasa wothandizira komanso zakudya za yisiti muzakudya.Coca-Cola ili ndi phosphoric acid.Phosphate ndi gawo lofunikira la chakudya ndipo lingagwiritsidwe ntchito ngati chowonjezera cha zakudya;

Makampani: Asidi wa Phosphoric ndi chinthu chofunikira chamankhwala, ndipo ntchito zake zazikulu ndi izi;

1. Tetezani zitsulo pamwamba kuti mupange filimu ya phosphate yosasungunuka pamwamba pazitsulo kuti muteteze zitsulo kuti zisawonongeke;

2. Kusakaniza ndi nitric acid monga mankhwala opukuta mankhwala kuti apititse patsogolo kusalala kwazitsulo;

3. Phosphate esters, zipangizo zopangira zotsukira ndi mankhwala;

4. Zida zopangira zopangira phosphorus yokhala ndi flame retardants;

Zoyenera kusamala mukamagwiritsa ntchito phosphoric acid:

Pofuna kuteteza khungu ku phosphoric acid, timalimbikitsa kuvala zovala zoteteza mankhwala monga nsapato, zovala zotetezera ndi magolovesi, timalimbikitsanso kuti mugule zikopa zopangidwa ndi mphira wachilengedwe, polyvinyl chloride, rabara ya nitrile, rabara ya butyl kapena zida zotetezera za neoprene.

Pofuna kuteteza nkhope kapena maso ku zinthu zonyansa ndi zowononga, timalimbikitsa kugwiritsa ntchito magalasi otetezera mankhwala.

Kuphatikiza pa mpweya wabwino wa utsi, timalimbikitsa kugwiritsa ntchito mpweya wopopera wopopa kuti mupewe zovuta za kupuma mukamagwiritsa ntchito phosphoric acid, kusamala zonse zofunikira pazachilengedwe ziyenera kuchitidwa, ndipo utsi ungafunikire kutulutsa mpweya kunja.
