aluminum hydroxideWhat are the other applications besides being a flame retardant?

1. Used as a filler for carpet backing latex foam and adhesive

The application of aluminum hydroxide in the carpet industry mainly uses the flame retardant filling performance of aluminum hydroxide. There are two kinds of latex in the blanket industry, one is adhesive and the other is foam. The carboxylated latex layer is an adhesive used to bond and fix the carpet fibers wrapped around the mesh backing; and the latex foam is applied to the carpet surface to achieve the required thickness. The curing is completed in the oven at 120~150 ℃. Typically, the binder is dosed at a ratio of 100 parts latex to 75 to 250 parts aluminum hydroxide, and in the foam at a ratio of 20 to 150 parts aluminum hydroxide per 100 parts latex. In general, the aluminum hydroxide used in carpets is a fine-grained aluminum hydroxide having a D50<20 μm.

2. Papermaking filler

Aluminium hydroxide is mainly used in the paper industry as a surface coating, filler and in the production of non-paper. In foreign countries, as early as the 4. and fifties have begun to develop and use aluminum hydroxide as a coating pigment, but in our country is still blank. Aluminum hydroxide as a coating pigment has many advantages: high whiteness, fine particle size and uniform particle size distribution, a flake crystal form, using it as a pigment can improve the whiteness of coated paper, opacity, flatness and ink absorption performance. Using it instead of titanium dioxide, without reducing the whiteness and opacity of the paper, can save costs, improve the gloss of the paper, improve the printing performance. Due to the fine particle size and uniform distribution of aluminum hydroxide, wear less, can extend the service life of the scraper, usually papermaking aluminum hydroxide particle size D50<1μm, whiteness> 99%.

3. Aluminium hydroxide for medical use

Aluminum hydroxide is one of the main ingredients of stomach medicine, and aluminum gel is a neutralizer of stomach acid, which is a traditional medicine for the treatment of stomach diseases. Now some of the new special stomach medicine also contains aluminum hydroxide ingredients.
