Product Application of Aluminium Potassium Sulfate With Delivery
Aluminium potassium sulfate dodecahydrate is a white crystal that is soluble in water. It is made by roasting alunite in a furnace and then harvesting the product by crystallization. Aluminium potassium sulfate dodecahydrate was used to harden gelatin emulsions by introduction, by bathing the exposed plates prior to development, or by use in the fixing bath with the inventory 2-3 working days New production 7-10 working days.
