Drop angle is defined as the solid and liquid. Three-phase interface of gas, gas - liquid interface and solid - liquid interface angle between the water droplet angle display scale solid surface humidity SDC-400 contact angle, the use of most solid objects on the droplet was measured SDC-300 The contact angle, low contact angle indicates high humidity (hydrophilic) surface easy to paste. High contact angle of water droplets display shows the surface hydrophobic, organic surface contamination is heavy or poor surface adhesion. The contact angle of the liquid and solid surface like a flat contact, through a liquid - measuring out the analysis of surface cleanliness SDC-900 contact angle junction point of contact in the gas and solid surface drops end of the curve, the contact angle is displayed solid - solid The contact angle of scale surface moisture, use most of the fixed droplet was measured, a low contact angle indicates high humidity (hydrophilic and hydrophobic), low surface energy. The main measurement methods: drop method, the amount of the Supreme Court, turn off method, insertion method, the hanging drop method, CMC critical micelle concentration of the surface to measure contact angles can also measure surface tension and CMC temporary work table size: 100mmX120mm10, countertops Size: 100mm * 120mm11, work Taiwan Mobile: about 50mm lower at the front and rear 50mm 30mm12, stretching up and down the table: 30mm surface boundary micelle concentration and provides a calculation of the solid surface energy.
