Wet Abrasion Scrub Tester with Image Recognition
Introduction: For the scrub resistance of wall paints and related products, operator should record the number of cycles to remove one continuous thin line of paint film across the 12.7mm(1/2 in.)width of the shim. But how to judge this 12.7mm length accurately? different operators always have their different judging standards. To accurately and quickly determine the end point of the test, it is not only necessary for the operator to have a preliminary prediction of the cycles of scrub resistance of the test samples, but also for them to be able to accurately identify the length of the removed paint film. However, it is quite difficult in actual operation.
BGD 526/S Wet Abrasion Scrub Tester with Image Recognition is equipped with the function of automatically identifying and calculating the length of the test sample from being abraded to the substrate (exposed bottom). It can monitor the wet abrasion scrub of the samples of two channels at the same time, no need to look at the sample on site. Once the exposed length of the test sample reaches the "threshold" set by the operator, the instrument will automatically stop and record the current scrub times, so as to truly achieve unattended. In addition, the operator can also browse the actual pictures of the test panel after scrubbing for any number of times, and can export the pictures to the U disk for checking.
Features:
◆ Double working channel, each channel can measure the length of the exposed bottom visually. When it reaches the set threshold, it will stop automatically.
◆ Equipped with 8-inch touch screen, which can display clearly and run smoothly.
◆ Compatible with a variety of abrasion pads to comply with different standards requirements, such as ISO, ASTM, DIN etc.
◆ Quickly and easily to load and unload testing samples and replacing abrasion head.
◆ Can work normally under different voltage and frequency.
◆ With the design of push rod, the running speed is stable and uniform.
◆ Features two brush holders for side by side testing.
◆ Long service life with hard and durable design.
◆ The whole machine body is made of anodized aluminum, having stable working status, repeatable test results, no exception even in the fastest speed of the stroke.
◆ The solution (scrub medium) flows into the brush through the peristaltic pump on the side of the tester, and can be accurately controlled.

BGD 746 Super High Speed Dispersing Machine integrates super high-speed dispersion, stirring and automatic control of lift distance. It can meet the application requirements of customers for super high-speed dispersion and homogeneous emulsification, with the excellent dispersion and emulsification effects, as well as high dispersing efficiency. In addition, this machine is operated by a large-size touch screen, which is powerful, convenient and practical.
Features
◆ Super high-speed motor: The max. speed can reach 20,000 r/min. Bigger torque, lower noise and lower power consumption.
◆ The max. lift distance can reach 300mm. Servo system for locating can precisely feedback the height information in real time.
◆ Dispersing blade can be set to stay at the required height, which is suited to different sizes of dispersing containers or different material levels. At the same time, the use safety can be improved.
◆ In the whole dispersing process, the dispersing blade can stir circularly between the set upper and lower limit. The lift distance and speed can also be set. Greatly improve the dispersion efficiency.
◆ With the 7-inch touch screen, the tip speed, torque ratio and the height of dispersing blade can be displayed in real time.
◆ Test parameters can be set, such as speed, run time, diameter, height, etc.
◆ Suitable for containers with the capacity of 0.5L-5L, and can meet more different test requirements.
A pendulum resting on a coating surface is set into oscillation and the time for the oscillation amplitude to decrease by an amount specified in this International Standard is measured. The shorter the damping time, the lower the hardness.
Two test procedures are considered in some detail, namely those of König and Persoz.(The Persoz and König methods differ by the period and amplitude of the oscillation. The Persoz test measures the time taken for the amplitude of oscillation to decrease from 12° to 4°; the König from 6° to 3°.)
The instruments embody the same principle — that the amplitude of oscillation of a pendulum touching a surface decreases more rapidly the softer the surface — but differ in respect of dimensions, period and amplitude of oscillation.
BGD 509/S Pendulum Hardness Tester is the newest product which can be used in accordance with the following National and International Standards: ISO 1522, ASTM D4366,BS 3900-E5,DIN 53157,NBN T22-105,NF T30-016.
It’s a simple to use instrument and can be supplied in one of three model types: Persoz, König, and Persoz and König combined
