Optical-grade anti-fog coating concentration accurate control device and using method thereof

Abstract

The invention relates to an optical-grade anti-fog coating concentration accurate control device and a using method thereof. The optical-grade anti-fog coating concentration accurate control device comprises an anti-fog coating tank, an anti-fog coating liquid storage tank, a diluent liquid storage tank and a water chiller. An outlet of the anti-fog coating liquid storage tank is connected with aninlet of a first industrial-grade diaphragm pump; an outlet end of the first industrial-grade diaphragm pump is connected with an inlet of a magnetic pump; the outlet end of the diluent storage tankis connected with the inlet end of a second industrial-grade diaphragm pump; the outlet of the second industrial-grade diaphragm pump is connected with the inlet of the magnetic pump; the outlet end of the magnetic pump is connected with the inlet end of a filter; the outlet end of the filter is connected with the inlet of the anti-fog coating tank; the anti-fog coating tank is installed in a circulating cooling water tank, and the inlet end of the circulating cooling water tank is connected with an outlet of a cooling water pump, and the inlet end of the cooling water pump is connected with an outlet of the water chiller. The temperature and concentration of an anti-fog coating in use are detected in real time, the temperature and concentration change trend is calculated through a PLC program, a diluent and the anti-fog coating are added in real time, and the temperature of the anti-fog coating is controlled through cooling circulating water, so that the anti-fog coating is at the optimal temperature and concentration.

Description

technical field [0001] The invention relates to the technical field of anti-fog paint concentration control, in particular to an optical-grade anti-fog paint concentration precise control device and a use method thereof. Background technique [0002] In the process of using anti-fog paint, diluent and anti-fog paint must be added at regular intervals to adjust the concentration of the liquid in the anti-fog paint tank. Too high or too low concentration will cause mass failure of optical products. Manually adding thinner and anti-fog paint can easily lead to concentration imbalance. At the same time, due to the high density of anti-fog paint and low density of thinner, adding a large amount of thinner or anti-fog paint at one time will cause liquid stratification. During this period, there are defects such as flow marks on the surface of the produced optical products. For optical products, the defect of flow marks will affect its imaging effect.

Problems solved by technology

[0002] In the process of using anti-fog coating, diluent and anti-fog coating should be added at regular intervals to adjust the concentration of the liquid in the anti-fog coating tank. Too high or too low concentration will cause a large number of defective optical products

Adding thinner and anti-fog paint manually will easily lead to concentration imbalance. At the same time, due to the high density of anti-fog paint and low density of thinner, liquid stratification will occur if a large amount of thinner or anti-fog paint is added at one time.

During this period, there are defects such as flow marks on the surface of the produced optical products. For optical products, the defect of flow marks will affect its imaging effect
