Aluminum hydroxide, as an necessary inorganic compound, includes complicated bodily and chemical adjustments for the duration of its storage process. The right storage approach now not solely ensures secure aluminum hydroxide properties, however additionally correctly prevents security risks, which is of extraordinary value for industrial manufacturing and laboratory research.
Environmental manipulate is the main component in the storage of aluminum hydroxide. Research has proven that temperatures exceeding forty ℃ speed up the dehydration procedure of aluminum hydroxide, main to its conversion to alumina. The perfect storage temperature ought to be managed between 15-30 ℃, and the relative humidity must be stored beneath 50%. Experimental facts suggests that beneath these conditions, the fine loss price of saved aluminum hydroxide can be managed inside 0.5% inside one year.
The desire of packaging substances at once impacts the storage effect. The inner packaging made of polyethylene material, blended with moisture-proof paper or aluminum foil bags, can efficaciously block moisture. It is advocated to use plastic drums or galvanized iron drums with suitable sealing for the outer packaging. Filling the drums with dry nitrogen can similarly decrease the chance of deliquescence. Comparative experiments have proven that the moisture content material of aluminum hydroxide packaged in double-layer packaging is greater than 60% decrease than that of single-layer packaging.
In phrases of storage management, strict working methods want to be established. Quality inspection have to be carried out earlier than storage, together with symptoms such as moisture content, pH value, and particle measurement distribution. The storage location must be geared up with a temperature and humidity monitoring gadget and bear ordinary environmental testing. It is advocated to undertake the first in, first out stock administration precept to make sure sensible cloth turnover.
Security measures can't be ignored. The storage place must be outfitted with moisture-proof and fireproof facilities, and stored at a secure distance from supplies such as robust acids and oxidants. Staff have to be outfitted with defensive gear and acquire everyday protection training. Through scientific administration and technological innovation, the storage security and steadiness of aluminum hydroxide can be utterly guaranteed.
