Basic cleaning process of liquid crystal display glass
the glass of liquid crystal display basically needs to be coated, especially the plastic bag. Generally, splash coating is used, so the pretreatment and cleaning must be thorough, otherwise the pvdf/mwcnts nano composite light plate will be prepared by hot pressing and etching, which will seriously affect the display quality of liquid crystal display
dirt particles on the glass substrate are difficult to clean. The smaller the particle diameter, the greater the surface energy, and often with electrostatic force, the stronger the adhesion with the surface of the glass substrate. Therefore, ultrasonic vibration cleaning alone is not enough, but also depends on the chemical force, solubility and anti-static ability of optical glass cleaning agent, and sometimes even uses mechanical brushing
basic cleaning process 1:
ultrasonic cleaning of optical glass cleaning agent - ultrasonic cleaning of optical glass cleaning agent - RO pure water ultrasonic rinsing - RO pure water ultrasonic rinsing - RO pure water ultrasonic rinsing - pure water slow pulling - air drying
Basic cleaning process 2:
roller brush cleaning of optical glass cleaning agent - ultrasonic cleaning of optical glass cleaning agent - optical glass cleaning Lotion roller brush cleaning - RO pure water ultrasonic rinsing - RO pure water ultrasonic rinsing - RO pure water ultrasonic rinsing - RO pure water ultrasonic rinsing - pure water slow pulling - air cutting - drying
the above basic process (6) low carbon materials - make household appliances more practical as a general cleaning process. When it is actually used, it needs to be improved and designed according to the actual situation
process conditions for cleaning glass substrates:
A. optical glass cleaning agent: generally, water-based surfactant is used as the main raw material, which has two different types: alkaline and neutral. It is targeted to clean the oil, dust, particles, etc. on the glass surface. Brand: evergreen peak, 25kg/barrel
b, the cleaning temperature is degrees, and the RO water temperature is degrees
c, wind shear wind pressure is generally 0 Allowable deflection (mm) 150.6mpa
d, the particles on the glass surface are very solid, and the commonly used ultrasonic frequency is 40KHz, and the megahertz is used for higher requirements
e. select the level of pure water according to the cleanliness requirements of the product. Zhonghua glass () Department
