2results about How to "Slow release rate" patented technology

The application relates to the technical field of supramolecular, in particular to a supramolecular salicylic acid and a preparation method and application thereof, the preparation method comprises the following steps: mixing salicylic acid, a ligand and an auxiliary agent, stirring and ultrasonicating to obtain the supramolecular salicylic acid; the ligand comprises L-lysine or arginine; and the molar ratio of the salicylic acid to the ligand is 1:1. The supramolecular salicylic acid prepared by mixing the salicylic acid and the ligand in a certain proportion and dissolving them in the auxiliary agent improves the solubility, stability and permeability of the salicylic acid. The supramolecular salicylic acid prepared by the application has good solubility and stability, strong permeability, small skin irritation, a simple and environment-friendly preparation method and is suitable for large-scale production.

This utility model belongs to the field of toilet cleaning technology, specifically a slow-release structure for toilet water cleaner, including a placement cylinder; a cap is detachably installed at the end of the placement cylinder via threads; a spring is fixedly connected to the side wall of the cap; a rubber block is fixedly connected to the other end of the spring; a release hole is fixedly connected to the middle of the rubber block; a first through hole is opened in the middle of the cap; an installation block is provided on the outside of the placement cylinder; a pair of circular cavities are opened in the middle of the installation block; a suction cup is fixedly connected to the end of the circular cavity; a pull rod is fixedly connected to one side of the suction cup located in the circular cavity; the pull rod is slidably connected to the middle of the installation block; with the above structure, after the block cleaner is placed into the toilet tank, the water liquid can come into contact with a small amount of block cleaner surface, thereby reducing the release rate of the block cleaner, and even when the block cleaner shrinks due to gradual release, the block cleaner can still come into contact with a small amount of water liquid and be slowly released.
