Live-working cleaner with low temperature gradient and application thereof

Abstract

The invention belongs to the technical field of cleaners, and in particular relates to a live-working cleaner with low temperature gradient and application thereof. The live-working cleaner comprisesthe following components (by weight): 20-30 parts of dichloromethane, 5-10 parts of HFE7100, 4-6 parts of tetrachloroethylene, 10-13 parts of high-boiling alkane of C11-C17, 20-25 parts of ODS substitute, 1-2.5 parts of a stabilizer, and 5-7 parts of a surfactant. The live-working cleaner has the characteristic of low temperature gradient, avoiding "condensation" and "ice crystal field effect" dueto high temperature gradient and reducing short circuit, burning plate and corrosion phenomenon. The product has characteristics of high insulation, non-combustion and environmental protection, and can deeply clean a power system.

Description

technical field [0001] The invention belongs to the technical field of cleaning agents, and in particular relates to a live working cleaning agent with low cooling gradient and application thereof. Background technique [0002] During the long-term continuous operation of electric and electrical equipment, due to the comprehensive pollutants such as various dust, salt, and oil floating in the atmosphere, and the formation of a water film dissolved in electrolytes such as salt due to condensation, through mechanical adsorption, the intermolecular The adsorption of electrostatic force and electrostatic force will cause serious pollution of electrical and electrical equipment, reduce the heat dissipation capacity of precision electronic equipment, and affect its operating quality and reliability. These pollutants also form additional "microcircuit effect" and "corrosion inhibition" effects on the circuits inside the equipment. Different degrees cause the error rate, failure ra...

Problems solved by technology

[0004] Because the cleaning agent will take away a lot of heat when it volatilizes, it is easy to appear "condensation" and "ice crystal field effect". "Condensation" and "ice crystal field effect" are different states of water deposited on the circuit, and water Combined with salt, alkali, acid and soluble acidic and basic oxides deposited on the circuit in the "harmful substances" to form a "strong and weak electrolyte solution" conductor, which can easily cause circuit short circuit, breakdown (burning board) ) and strong corrosion

The cooling gradient, boiling point, and latent heat of evaporation jointly affect the cooling gradient. When the cooling gradient is too large, the electronic components with a small expansion coefficient will break, and the strength and electrical properties of the electronic component materials will change, causing unknown communication failures or major accidents. occur
