Contact angle and surface tension in glass cleaning and coating
We know that materials with high surface free energy are very suitable for bonding and coating, such as glass, however, hydrophobic substances are easily adsorbed on the glass surface, which makes bonding and coating do not work well. Therefore, it is necessary to thoroughly clean the glass surface, and use the interface chemical method to ensure the cleaning quality. At this time, it is necessary to use a contact angle meter to measure the contact angle, surface free energy, surface tension and other information of the glass surface to ensure the glass surface. cleanliness to meet the coating requirements.
Some applications do not require glass to have good wettability, such as spectacle lenses, car windshields, etc., and usually need to coat the glass with hydrophobic materials. The measurement technology of Shengding contact angle measuring instrument can be used for non-stick Development and testing of coatings; testing the glass with a contact angle meter can clearly know whether the glass product is hydrophobic or hydrophilic, so that it can be used for different applications.
The application of contact angle measuring instrument to glass surface analysis
Glass window glass bonding, hydrophobic coatings (automotive glass, eyeglass lenses, shower walls), shatter protection, easy cleaning and self-cleaning, coatings, graffiti protection, UV protection and more.
Sindin Precision Portable Contact Angle Measuring Instrument
There are many companies that have a problem when measuring the contact angle of large-area glass. The glass area is too large, and sometimes they don't want to cut a part of it, and cut a large piece of glass. In response to this problem, Shengding Precision has specially developed a A SDP-300 portable contact angle measuring instrument, used to measure large size, large volume, uncut, difficult to move and other oversized products, specially designed for contact angle measurement of large samples, such as glass, automobile manufacturing, etc. The measurement needs of the industry, and this product is light and easy to carry, and the size of the measurement sample is limited, allowing you to measure anytime, anywhere!
