    Formula of grinding material of sand mill Daniel flow point method is a basic method, but the operation is really tedious

    For the sake of simplification, the "practical formula area diagram of abrasive slurry composition of sanding mill", which is called trigonometric coordinate diagram for short, is a simple and practical method

    As shown in Figure 12.8, III

    high speed disperser See Figure 12.9 for the structure of high-speed disperser

    For the pigments after surface treatment, such as the imported rutile titanium dioxide and the coatings which are not suitable for sanding, ball milling and roller grinding, such as gray mica iron oxide enamel, they can be separated by high-speed disperser Paint agent, top 10 Chinese wall paint brands Recommended introduction: interior wall paint and exterior wall paint can achieve beautiful, clean and pleasant effects, but the effects in different environments are different, so the color of the paint will be different

    Although Daniel flow point method is a basic method, it is really cumbersome to operate

    For the sake of simplification, the "practical formula area diagram of paint slurry composition of sand mill" developed is a simple and practical method

    As shown in Fig

    The structure of high-speed disperser is shown in Fig

    12.9

    For the pigments after surface treatment, such as the imported rutile titanium dioxide and the coatings which are not suitable for sanding, ball milling and roller grinding dispersion, such as gray mica iron oxide enamel, they can be dispersed by high-speed disperser and directly made into finished paint slurry

    The high-speed disperser is composed of paint with low viscosity (actually low solid content) and paint with high pigment volume fraction

    According to the analysis of the actual data of the high-speed disperser used in the production, Guggenheim has derived the relationship between the solid content (NV), viscosity (η) and oil absorption () of the paint and the most appropriate paint pigment quality ratio, that is, Guggenheim empirical formula

    WV is the quality of paint; WP is the quality of pigment
