DEYOTE JY-PHB contact angle analyzer, droplet shape analyzer

Introduction

The contact angle is the angle between the gas-liquid interface and the solid-liquid interface at the junction of gas, liquid and solid phases, and is represented by θ. The main function of the contact angle measuring instrument is to measure the contact angle of liquid to solid, which is an important instrument for surface performance testing.

JY-PHB contact angle measuring instrument analyzes and measures contact angle, forward angle, back angle, rolling angle, surface energy, wetting performance and other indicators through the acquisition of image contour, the instrument is cost-effective, comprehensive functional, and can meet the needs of various conventional measurements and some unconventional measurements.

apply

Contact angle measuring instrument is widely used in popular fields we are familiar with, such as medical, chemical, surface treatment, glass manufacturing, as well as screens, lenses, semiconductors, electronic circuits, coatings and inks, biological sciences, textile fibers, and major universities for material research and analysis, in short, contact angle measuring instrument is an important measuring instrument to evaluate surface properties.

Features

1. The seat drop method is used to measure the static contact angle. (e.g. spreading, penetration, absorption and other wetting behaviors of liquids on solid surfaces)

2. Measure the dynamic contact angle including: rolling angle, forward angle, backward angle. (According to the hysteresis of the contact angle, analyze whether the surface of the material is uniform and flat)

3. Real-time monitoring of the change of contact angle and surface energy of the material, and generate curve analysis diagram according to time and result.

4. Measurement of powders, non-planar materials (concave and convex surfaces), superhydrophobic and superhydrophilic materials.

5. Calculation of automatic energy, dispersion force, polar force, non-polar force, electron acceptor, and electron donor on solid surface.

6. Calculation of adhesion work, wetting work, and spreading coefficient

Operating principle (the appearance of the instrument is mainly based on the actual factory)

The contact angle measuring instrument is mainly composed of 5 parts

• Hardware drive system: It provides physical support for the overall operation of the instrument, the work of the dispensing system, the display and adjustment of the light source, the normal operation of the software, the analysis of the results, and the data transmission.

• Manual liquid feeding system: accuracy 0.1 μL.

• Sample stage: Three-dimensional sample stage, fine workmanship, strong sense of operation damping, stable movement, accurate positioning, domestic high-precision optical rotary table is used to realize the forward angle, backward angle and rolling angle of the rotation method.

• Image acquisition: SONY high-speed industrial-grade chip, 30 frames/s, 300W pixels, driver-free, USB power supply plug and play, no need for separate power supply.

• Powerful software analysis system, with internationally popular fitting methods, accurate and fast completion of measurement tasks; Powerful database support, which can store 2 million test records, and the historical records can be retrieved and consulted instantaneously.
