LED gallium arsenide substrate dewaxing cleaning agent

Abstract

The invention provides an LED gallium arsenide substrate dewaxing cleaning agent which comprises the following components in percentage by weight: 5 percent to 10 percent of organic solvent, 2 percent to 5 percent of organic alkali, 5 percent to 10 percent of surfactant, 5 percent to 20 percent of inorganic salt and the balance of de-ionized water. The organic solvent is alkane, naphthenic hydrocarbon or aromatics solvent; the organic alkali is polyhydric polyamine, pegamine, hydroxylamine or hydramine, the surfactant is one or more than one of fatty alcohol polyoxyethylene ether, polyol ester and macromolecule and element organic compounds, and inorganic salt is basic salt. In the invention, the LED gallium arsenide substrate dewaxing cleaning agent can replace halogenated hydrocarbon solvent, not only can achieve the cleaning effect of halogenated hydrocarbon solvent with obvious dewaxing effect, and but also has no influence on gallium arsenide substrate and simple preparation process, and can meet the requirement of environment protection.

AI Technical Summary

Benefits of technology

This patented technology provides methods for creating high purity products with reduced volatile content by mixing different types of liquids together at specific temperatures or times during processing. By doing this, it becomes possible to improve product quality without harmful residues from previous processes. Additionally, these new technologies allow for efficient separation between components based on their physicochemistry characteristics such as polarizabilities (ionic charges), molecular size). Overall, this process allows us to produce highly pure materials while reducing waste production and minimizing any negative impact upon our surrounding environments

Problems solved by technology

The technical problem addressed by this patented solution relates to finding an effective way to remove unwanted waxy material during manufacturing processes without harmful environmental effects caused by traditional methods like chlorinating acrylic acid (CA) with fluorochemistry chemicals called perfluorooctanoycloneophilum(PF), which can be expensive and cause damage to our environment through volatility intoxic gases released when burning them at high temperatures.
