Phosphoric Acid
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.
