Description
Technical field
The present invention relates to LCDs technical field, and in particular to a kind of high-efficiency washing method of TFT-LCD liquid crystal displays.
Background technology
Liquid crystal is the material that a class has property, and it keeps crystal distinctive within the specific limits in a liquid state
It is capable of the feature of ordered arrangement in three dimensions.The liquid crystal material used on liquid crystal display is with cholesterol ester, cyanobiphenyl, benzene
The organic compound of the class formations such as butylcyclohexane.It is total on its periphery after liquid crystal material is encapsulated into the middle of two panels electro-conductive glass
Unnecessary liquid crystal material can be remained, the performance of liquid crystal display will be influenceed if do not washed, when serious even corroding electrode lead,
Complete machine is caused to scrap.Therefore, in the production process of liquid crystal display, cleaning performance directly affects the reliability and finished product of liquid crystal display
Rate.
The aqua type cleaning agent used in the world in LCD production industries at present mainly adds bleeding agent, surface in water
Activating agent and other auxiliary agents are cleaned, wetting, emulsification and peptizaiton using bleeding agent to greasy dirt, along with surface-active
Agent and other auxiliary agent booster actions, it is adaptable to the cleaning of various greasy dirts, it is nonflammable to human body non-hazardous on environment without influence.It is right
In the cleaning of liquid crystal, can be added in water has preferable solvability to liquid crystal material, and the preferable surface of penetrating power is lived
Property agent, wetting agent, water-soluble agents so that the liquid crystal washed down can be preferably dissolved in cleaning fluid, by surfactant
Emulsification, so as to depart from surface to be cleaned.But it has the disadvantage to clean more difficult to blind hole, and cleaning fluid is not recyclable, and cleaning equipment is once
Investment is larger.The unprocessed direct discharge of the substantial amounts of waste water containing chemical active agent and dirt is more seriously caused, seriously
Ground contamination environment, it is necessary to increase sewage treatment facility.
The content of the invention
The present invention is intended to provide a kind of high-efficiency washing method of TFT-LCD liquid crystal displays.
The present invention provides following technical scheme：
A kind of high-efficiency washing method of liquid crystal display, comprises the following steps：
(1) liquid crystal display cleaning fluid is put into the first groove, 50-60 DEG C is heated to, liquid crystal display is immersed in the first groove, matched somebody with somebody
Close ultrasonic wave or million sound effect cleaning 3-5min；Electrochemical oxidation liquid is put into the second groove, 50-60 DEG C is heated to, by liquid crystal
Screen takes out from the first groove to be put into the second groove, coordinates ultrasonic wave cleaning 3-5min；
(2) deionized water is put into the 3rd groove, is heated to 50-60 DEG C, liquid crystal display is taken out from the second groove and is put into
In three grooves, coordinate ultrasonic wave cleaning 3-5min；
(3) liquid crystal display after cleaning is sprayed with the deionized water that temperature is 50-60 DEG C, the time is 2-4min；Spray
Liquid crystal display after pouring is dried.
Cleaning fluid is mixed by anion surfactant, organic base and water in the step (1), its weight
For：85-92 parts of 2-5 parts of anion surfactant, 3-8 parts of organic base and water.
The anion surfactant is dodecane hydrocarbon sodium sulphate or the sour sodium of dodecylphenyl.
Electrochemical oxidation liquid is to utilize diamond film anode electrolysis water in the step (1), and it is strong that electrochemical oxidation is generated
Oxidizing anode groove electrolyte.
Drying is uses infrared drying in the step (3), and the temperature of drying is 85-95 DEG C, and the drying and processing time is 9-
12min。
Compared with prior art, the beneficial effects of the invention are as follows：In the TFT-LCD liquid crystal display cleaning methods of the present invention, adopt
The Strong oxdiative anode slot electrolyte generated with diamond film anode electrolysis water coordinates ultrasonic wave to clean, the oxidizing component of the electrolyte
For the hydrogen peroxide of saturation, dissolved ozone, it organics removal and cleaning agent can effectively remain, not only increase organic pollution
Removal effect, it is often more important that can avoid producing a large amount of waste water containing cleaning fluid, eliminate the environmentally friendly hidden of aqueous-base cleaning
Suffer from, disclosure satisfy that environmental requirement.
