Nano diatomite JSY660
Nano diatomite JSY660 is the amorphous particles of powder or granular, has the very high insulation, insoluble in water and common acid, soluble in caustic and hydrofluoric acid, the high temperature decomposition, water imbibition, non-toxic
Nano diatomite JSY660 added to the coating can improve the scrub resistance, strength and hardness of the coatings, etc. Adding a small amount of nano diatomite in coating, coating of anti-ultraviolet aging test performance can be increased from the original 250 h to 600 h above, scrub resistance increased by more than 10 times, greatly reduce drying time, low Thixotropy Bright and clean degree is not high also get a better solution
Add nano diatomite JSY660 coating effect also obviously improve the cans, coating stratification, prevent sagging, good workability, the fouling resistance is greatly increased, and excellent self-cleaning and adhesion
Nano diatomite JSY660 in coating application features：
Resistance wash:Wash resistance from thousands of times to tens of thousands of times
Weather:Weather resistance can be improved about three times, add a certain amount of nano diatomite JSY660 can make the ultraviolet aging resistance of traditional coating product from the original 250 h to 600 h above
Tarnish resistance and self-cleaning:Study shows that the coating can be improved through the following approaches the fouling resistance and self-cleaning, one is the use of nano silica microporous structure, through a certain process means formed on the coating surface geometry nanometer scale complementary, such as convex and concave and interface structure, make its adsorption and air on the surface form a stable layer of gases trap film; Second, diatomaceous earth nanoparticles for surface treatment, make its surface rendering parents or double hydrophobic property, effectively improve the rain wetting and dust on the surface of architectural coatings coating adhesion, improving the contamination resistance of coating and self-cleaning ability
Antimicrobial properties:In coating, when the adding amount of nano diatomaceous earth JSY660more than 0.5%, the coatings showed obvious antibacterial effect
Hydrophobic anticorrosion: nano diatomite JSY660 hydrophobic anti-corrosion coatings, not only has the good adhesion and corrosion resistance, and high density and resistance to permeability of ions
Transparency:Nano diatomite JSY660 Whiteness reaches 98, can ensure the transparence of nano modified coatings. Diatomite can be obtained using nanometer high wear-resisting transparent coating, the wear resistance is more than 10 times greater than that of the original
Hardness: when diatomite JSY660 nanoparticles in organic material single particles dispersed homogeneously, nanoparticles as rigid chain to enhance the role of organic material, so as to improve the coating hardness of uv-curable coatings, up to more than 2.5 times
Thermal stability: in uv-curing coatings, nano diatomite JSY660 can improve coating glass transition temperature
Viscosity: nanometer diatomite JSY660 join can significantly increase the viscosity of the coating
Content:The practice has proved that by adding 2% of diatomite in the coating, the coating hardness, adhesion, weather resistance, and the viscosity of the coating and anti-settling ability and stability of coatings to achieve a better state. Recommended dosage is 0.5-2%, individual product system by more than 10%, should according to actual situation
Method of use:Nano diatomite JSY660 dispersion can use a variety of methods, such as grinding, high speed shearing, ball mill, sand grinding, ultrasonic dispersion, etc., of which the former two methods to use more. Nano diatomite JSY660 added to the coating, its dispersion step into one-step and two-step
One-step refers to adding nanometer diatomite JSY660 products directly to get the required must be content in the raw material system products, one-step method is characterized by simple production process, is suitable for large quantity, the product of a single production
Two steps is to scatter nano diatomite by higher proportion to material masterbatch, diluted and then add the ingredients to the certain proportion. Two step is due to the characteristics of high viscosity, dispersion when shear force is bigger, the better dispersion of nano diatomite JSY660, suitable for many kinds of production. At present, the domestic product quality good enterprise to use separate ways mainly adopts one-step high-speed shear, can basically meet the need of users
