Automatic droplet angle measuring instrument tests the hydrophilicity and hydrophobicity of glass after cleaning

The contact angle tester is mainly used to measure the contact angle formed by liquids on solid surfaces. When a droplet of liquid is placed on a solid surface, it forms a special angle, which is the contact angle, which intuitively reflects the wettability of the liquid on the solid surface. The working principle of the contact angle tester is based on optical imaging and advanced algorithm analysis. High precision cameras capture the shape of liquid droplets on solid surfaces, and then software uses complex algorithms to accurately calculate the size of the contact angle.

Car windshield washer fluid refers to a liquid used in conjunction with car wipers to remove dirt from the surface of car windshields. Automotive windshield cleaning solution is composed of various surfactants and additives. Surfactants usually have functions such as wetting, penetration, and solubilization, thus playing a role in cleaning and removing dirt.

Carry out testing of automotive windshield cleaning solution, including freezing point, pH value, appearance, and cleaning power at low usage concentrations,

Testing Scope

Automotive windshield cleaning solution is mainly divided into water-based and hydrophobic types according to its components. Water based automotive windshield cleaning solution is divided into ordinary and low-temperature types according to its freezing point.
