This invention relates to a method for synthesizing dust-free
silica gel cat
litter at the source. Its morphology and mesoporous structure can be controlled at the source according to usage requirements, belonging to the field of pet product
manufacturing technology. This method uses
sodium silicate and an acidic solution as raw materials. By controlling the pH, temperature, and reaction time during the gel synthesis stage, the density of hydroxyl groups and the pore structure of the
silica gel surface can be controlled at the source. Further optimization of its mesoporous structure and surface properties is achieved through treatment in an
alkali metal salt solution. This method eliminates the need for subsequent
resin coating or chemical additives, simultaneously achieving dust-free, high-adsorption, long-lasting
odor-locking, and structural antibacterial functions at the synthesis source. The resulting
silica gel cat
litter has low dust content, high water absorption, and strong adsorption capacity for odors such as
ammonia. The production process covers the entire process from synthesis and modification to sorting and packaging, making it suitable for large-scale
continuous production. It solves the problems of balancing performance and
environmental protection, unstable
quality control, and fragmented industrial chains inherent in traditional processes.
