Where is the contact angle cheap, ShengDing instruments, Heyuan City, the contact angle is provided by Dongguan Sheng Ding Precision Instrument Co., Ltd .. Dongguan Sheng Ding Precision Instrument Co., Ltd. (www.gdshengding.com) is a specialist in the "contact angle measurement, tensile tester, drop angle detector, tables, interface equipment," the company. Since its inception, we adhere to the "honesty, sound management" approach, the courage to participate in healthy competition in the market, so that the "" brand has a good reputation. We adhere to the "service first, customers first" principle, so ShengDing instrument has won the trust of customers congregation in chemical instrumentation, and establish a good corporate image. Special Note: This information is for reference pictures and information, please contact us to obtain the most accurate information, thank you! The above mentioned Conic law had also been included circular method, because the circle of a quadratic equation is just a special case. When the volume of the droplet is large, or a large proportion of the liquid, or liquid surface tension of the contact angle is relatively small price, the formation of a significant breach of its spherical shape, at the moment the use of this approach can cause considerable measurement error will be large to a few degrees. So be sure to pay attention to the limitations of this approach. Advocates of this approach is only used in calculating the droplet droplet contact angle of less than 30 degrees, or the shape of equal or close to the ball. C2000 series has a contact angle measuring instrument instantly freeze, automatic continuous photography, high speed photography three kinds of shots the way, even the volatile liquid can also ensure accurate measurement. Meanwhile, outside the influence of subjective factors tangent is the biggest problem, JC2000 series of contact angle measurement of the geometric operations being done in software, the contact angle is no longer human judgment. Electric ultrasonic particle size analysis points ultrasound analysis is the latest emerging methods of particle size analysis, particle size measurement range is 5 ?? m ~ 100 ?? m. It's more complex analysis principle, simply put, when the sound waves within the sample conductivity, the instrument can analyze the sound wave attenuation values ??over a wide range of ultrasonic frequencies, through the measured acoustic attenuation spectra can be calculated attenuation value and size of the book relationship. Parameter analysis of thermal expansion and the liquid required in the density of the particles, the viscosity of the liquid mass fraction of particles in the contact angle and other parameters quoted, emulsion or colloidal particles in a flexible, but also the particles (including the particle, ξ electric potential, etc.) contact angle direct, without dilution, avoiding laser particle size analysis method can not analyze a high concentration dispersion particle defects, and high precision, a wider range of particle size analysis.
