Application:
Mainly used in producing various phosphate, phosphate treatment on metal surface, compounding electrolytic and chemical polishing liquid and used as a catalyst, drying phosphate refractory clay,inorganic adhesives,used as a metal antirust paint in Coating industry.
Packing: 200L,300KG Phosphate barrel (590mm*910mm) 80 barrel/ 20GP. Total 26.4MT/20GP
1000L,1600KG Phosphate IBM (1200mm*1000mm*1150mm) 18 IBM/20GP. Total 28.8MT/20GP
23L,35KG Phosphate barrel(295mm*265mm*375mm,Caliber: 45mm)
Packing and Storage: Stored in Polyethylene plastic drum and must be tight closure by inside cover and outside cover. It is secondary inorganic acidic corrosive substances, and the IMDG Code is 93002. It’s easy to icy in winter. The net weights is :35kg-330kg-1000kg. Should be stored in a cool, well-ventilated area inside. High concentration of phosphate in winter cold area should pay attention to heat preservation, prevent freezing, prevent vessel rupture occurred leakage. Not with base classes, toxic substances and other corrosive materials common storage mixed luck. Transportation to prevent rain and sun exposure. When loading and unloading to gentle with, it is strictly prohibited to violent collisions, prevent packing container rupture. Fire, can use dry sand, dry powder fire extinguisher saves.
