AI Technical Summary

Technical Problem

Existing pet deodorizing products suffer from low adsorption efficiency, easy bacterial growth, insufficient safety, and environmentally unfriendly manufacturing processes, failing to effectively address the need for cleaning pet urine odors and stains.

Method used

Pet-specific activated carbon is prepared using biomass materials. Through crushing, drying, degreasing and impurity removal, microwave or hydrothermal carbonization activation, surface modification and functional compounding, a porous activated carbon intermediate is prepared and loaded with antibacterial agents and enzyme preparations to form a finished product suitable for removing odors and antibacterial properties of pet urine.

Benefits of technology

It improves adsorption efficiency, inhibits bacterial growth, reduces production energy consumption, ensures product safety and non-toxicity, and has antibacterial and humidity-regulating functions, making it suitable for pet beds, cat litter, and other applications.

Abstract

The application provides a method for preparing pet special activated carbon by using biomass materials, and relates to the technical field of activated carbon preparation. The method uses pet safe and harmless biomass materials as raw materials, and prepares high specific surface area activated carbon by using a microwave assisted activation method or a hydrothermal carbonization activation method after pretreatment. Then, the surface modification processes such as pH adjustment, antibacterial system loading and enzyme preparation compounding are carried out, so that the activated carbon is endowed with the ability of targeted adsorption of pet urine ammonia, sulfide and other odor molecules. Meanwhile, the activated carbon has the functions of antibiosis, mildew prevention and odor neutralization. The core innovation lies in the optimization of biomass raw material pretreatment, the low energy consumption and high efficiency activation process, the pet special multifunctional modification system and the whole process safety control. The prepared activated carbon has an urine stain removal rate of greater than or equal to 90%, and an antibacterial rate of greater than or equal to 95% on escherichia coli and staphylococcus aureus. The method is environmentally friendly and energy-saving, and has high preparation efficiency. The product is suitable for pet nest pads, cat litter, cleaning sprays and other scenes, and provides a safe and efficient solution for pet environmental health.
