    What is Silicon Dioxide?

    Silicon dioxide, an inorganic compound with the chemical formula SiO2, is a long-range ordered arrangement of silicon and oxygen atoms to form crystalline silicon dioxide and a short-range ordered or long-range disordered arrangement to form amorphous silicon dioxide. 
    Silicon dioxide has the chemical formula SiO2 and is available in both crystalline and amorphous forms. 
    Silicon dioxide has a wide range of uses, mainly used in the production of glass, water glass, pottery, enamel, refractory materials, aerogel felt, ferrosilicon, type sand, monomorphous silica, cement, etc. In ancient times, silicon dioxide was also used to make glaze and carcasses for porcelain.

    Application 

    1. It is beneficial to enhance the adhesion of the slurry to the fiber, and there is strong or weak hydrogen bonding between the active hydroxyl group on the surface and the hydroxyl group on the starch and cotton fiber, which can effectively improve the sizing performance of pure cotton and polyester cotton yarn.

    2, nano silica is more conducive to the sizing of cellulose fibers.

    3, with the effect of enhancing and increasing wear and reducing hair.

    4. The slurry film of nano-silica mixed slurry has abrasion resistance compared with that of pure starch slurry.

    5, improve the integrity and penetration rate of the slurry film.
