Method for detecting automobile washing cleanliness

Abstract

The invention discloses a method for detecting automobile washing cleanliness. The method comprises the following steps: selecting a transparent material as a base material, wherein the light transparency of the transparent material is P0; coating the surface of the base material with a testing solution, and drying in air so as to obtain a sample plate with a standard coating layer; testing the light transparency P1 of the sample plate; flashing the sample plate with jet water of which the water pressure, the flow velocity, the flow, the angle, the water quality and the working time are recorded, so as to remove the coating on the surface of the base material; baking the sample plate; testing the light transparency P2 of the baked sample plate; and comparing differences of the light transparency P0, P1 and P2, and analyzing a dirt removal effect. The method has the advantages that by testing the variation of the light transparency before and after the sample plate is washed, the dirt removal property of a corresponding jet water cleaning process can be represented through quantization results, the operation is simple, the process is stable, the cost is low, the result is definite, the problem of evaluating the surface cleaning property of a cleaning process can be well solved, and base material damage situations can be also observed and analyzed.

Description

technical field [0001] The invention relates to a technology for detecting the cleanliness of a car wash, in particular to a method for detecting the cleanliness of a car wash. Background technique [0002] Water jet technology refers to the method of applying a beam of high-speed water jetted from a small-diameter hole to the material. It is a technology to remove dirt by physical means. This technology has many advantages in cleaning effect and environmental protection. It is applied in Car surface cleaning, high-rise building exterior wall cleaning, road marking removal, ship cleaning and many other fields. After adopting a certain water jet technology and process, people need to evaluate its cleaning effect. In reality, people mainly rely on visual inspection, which directly affects the objectivity of evaluation, affects the results of technical analysis, the efficiency of process improvement, and cannot accurately record the test results. In terms of quantitative eval...

Problems solved by technology

However, if this method and device are used to evaluate the cleaning effect of the automobile surface cleaning process, the technology is complex, the cost is high, the operation is inconvenient, and the practicability may not even be as good as the qualitative evaluation of conventional visual inspection, so it is difficult to implement and promote in practice. Still needs further improvement
