Udindo wa phosphoric acid - Hebei Pengfa Chemical Co. LTD,
opanga zoweta phosphoric acid, Phosphoric acid, Phosphoric acid ndi kugwiritsa ntchito kwake, Opanga PHOSPHORIC ACID, othandizira phosphoric acid, othandizira phosphoric acid ku China,
Physicochemical katundu:
1. Zamadzimadzi zowoneka bwino zopanda mtundu, Palibe fungo loyipa
2. Malo osungunuka 42 ℃; kutentha kwa 261 ℃.
3.Kusakanikirana ndi madzi mu chiŵerengero chilichonse
Storge:
1. Sungani m'nyumba yosungiramo zoziziritsa komanso mpweya wabwino.
2. Khalani kutali ndi gwero la moto ndi kutentha.
3. Phukusili ndi losindikizidwa.
4. Iyenera kusungidwa padera ndi zoyaka mosavuta (zoyaka) zoyaka, ma alkali, ndi ufa wachitsulo wokangalika, ndikupewa kusungirako kosakanikirana.
5. Malo osungirako ayenera kukhala ndi zipangizo zoyenera kuti zikhale ndi kutaya.

Gwiritsani ntchito:
Kugwiritsa ntchito paulimi: feteleza wa phosphate ndi zakudya zopatsa thanzi
Kugwiritsa ntchito mafakitale: zopangira mankhwala
1.Tetezani zitsulo kuti zisawonongeke
2.Kusakaniza ndi asidi nitric monga mankhwala kupukuta wothandizila kukonza pamwamba mapeto a zitsulo
3.Zinthu za phosphatide zomwe zimagwiritsidwa ntchito pochapa mankhwala ndi mankhwala ophera tizilombo
4.Kupanga phosphorous yomwe ili ndi zinthu za flameretardant.
Zakudya zowonjezera zimagwiritsidwa ntchito: kununkhira kwa acidic, Yisiti Nutri-ents, monga coca-cola.
Kugwiritsa ntchito kuchipatala: kupanga mankhwala okhala ndi phosphorus, monga Na 2 Glycerophosphat
Ntchito zazikulu za phosphoric acid:
1. Phosphoric acid ndi zopangira zopangira feteleza wofunikira wa phosphate (calcium superphosphate, potassium dihydrogen phosphate, etc.), komanso zopangira zopangira chakudya chamagulu (calcium dihydrogen phosphate).
2, kuchitira zitsulo pamwamba, kupanga insoluble mankwala filimu pamwamba zitsulo, kuteteza zitsulo kuti dzimbiri.
3, wothira nitric acid ngati kupukuta kwa mankhwala, kuti apititse patsogolo kutha kwa chitsulo.
4, kupanga zinthu zochapira, mankhwala ophera tizilombo phosphate ester.
5, kupanga zipangizo munali phosphorous lawi retardant.
6, phosphoric acid ndi chimodzi mwazowonjezera chakudya, mu chakudya monga wowawasa wothandizira, yisiti zakudya wothandizira, kola lili phosphoric acid. Phosphates ndi zofunikanso zowonjezera chakudya ndipo angagwiritsidwe ntchito monga zowonjezera michere.
7. Phosphoric acid angagwiritsidwe ntchito kupanga mankhwala okhala ndi phosphorous, monga sodium glycerophosphate.
Phosphoric acid kapena orthophosphoric acid, mankhwala chilinganizo H3PO4, molekyulu kulemera 97.994, ndi wamba inorganic asidi, ndi sing'anga amphamvu asidi. Amapezeka mwa kusungunula phosphorous pentoxide m'madzi otentha. Orthophosphoric acid imapezeka mwamalonda pochiza apatite ndi sulfuric acid. Phosphoric acid imataya madzi mosavuta mumpweya. Kutentha kumataya madzi kukhala pyrophosphoric acid, ndipo kumataya madzi kukhala metaphosphate.
