Abstract

The invention relates to the technical field of glass detection and especially provides a detection method of surface energy of glass. The detection method includes the following steps: controlling temperature to be 18-22 DEG C and relative humidity to be 40-60%; cleaning a to-be-tested glass surface; selecting any three from diiodomethane, distilled water, formamide, ethylene glycol and glycerol as detection fluids, of which surface energy parameters are known, and measuring equilibration time that the detection fluids are equilibrated on the to-be-tested glass surface; selecting at least three dropping points on the of the to-be-tested glass surface and performing measurement with a contact angle measuring instrument, and calculating the average value of measurement data, which is the equilibration contact angle of the detection fluids on the to-be-tested glass surface; and calculating the surface energy of the glass according to formulas. The method has quick speed, high precision, good stability and low environmental pollution.

Description

Technical field:

[0001] The invention relates to the technical field of glass detection, in particular to a method for detecting glass surface energy. Background technique:

[0002] After the glass product is coated or surface treated, the treatment effect and bonding performance cannot be distinguished by the naked eye. By measuring the surface energy of the glass product, the bonding performance with the glass glue, bus bar and other accessories can be accurately judged, thereby reducing rework or Waste of defective products.

[0003] The current glass surface energy detection uses the dyne pen measurement method. Specifically, dyne pens with different surface tension values ​​are used to paint the glass surface. If it is not wetted, replace the dyne pen with a relatively lower value and repeat In this step, the dyne liquid can soak the glass surface (the liquid can spread out), and the surface tension value shown by the dyne pen is the surface energy of the glass. However, the...
