There are three drop test comparison angle, strictly control each level, to ensure the highest quality product condition: After coating or surface treatment process dynamic drop angle measurements, the naked eye can not distinguish the treatment effect, whether touching fingerprint-proof and abrasion condition angle, angle measurement by drop, to reduce rework defective products or waste. Drop angle measurement instrument Rationale: defined as the angle of water droplets in solid and liquid. Three-phase interface of gas, gas - liquid interface and solid - angle end of the contact angle measurement liquid interface between water droplets angle display scale solid surface moisture dynamic contact angle tester, the use of most fixed objects droplets measured 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 end point of contact and a solid surface gas junction in the curve drops - solid. The firing temperature of the ceramic body to develop a factory waste, re-use expansion when burned, it is difficult to determine the firing system. High temperature expansion and contraction of the visual appearance can be visually observed not only in the firing process of the body changes, but also capable of expansion and contraction rate for real-time measurement of body. Dynamic contact angle measurement, Sheng Ding equipment (certified), the contact angle provided by the Dongguan City Ding Sheng Precision Instrument Company.
