Device and Method for Magnetizing Glass Fragments for Safe Pick-Up
20240091788 · 2024-03-21 ·

A metal-infused liquid glass product or coating and a method for safely picking up glass shards from a surface. The invention provides a clear metal-infused liquid stored in an aerosol can, designed for easy application on a glass surface or onto glass shards. The liquid is sprayed onto the glass surface or glass shards using a nozzle, adheres to the surface, and dries within a specific time period. Once dried, the liquid forms a transparent coating on the glass, enabling for unobstructed visibility. The liquid contains micro metallic particles that impart magnetic properties to the glass shards, making them easily attractable with a conventional magnet. The magnet can be used for attracting and picking up glass shards without using any other device. The invention simplifies the process of collecting and removing glass shards, thereby providing enhanced safety and convenience.

Substrate cleaning apparatus and substrate cleaning method

A processing solution containing solvent and solute is supplied onto a substrate (9). The processing solution transforms into a particle retention layer as a result of at least part of the solvent being volatilized from the processing solution and causing the processing solution to solidify or harden. The particle retention layer is removed from the substrate (9) by supplying a removal liquid onto the substrate (9). A solute component contained in the particle retention layer is insoluble or poorly soluble in the removal liquid, whereas the solvent is soluble. The solute component contained in the particle retention layer has the property of being altered to become soluble in the removal liquid when heated to a temperature higher than or equal to an alteration temperature. The removal liquid is supplied after the formation of the particle retention layer, without undergoing a process of alternating the solute component.
