① Intelligent Fineness of Grind Gauges

Introduction: There are often large differences in the result judgment of scraper fineness, especially for low range fineness of grind gauges. One of the reasons is that the strength and speed of different operators are different when scraping the sample in the groove with a scraper. The second reason is that when reading, there are relatively large subjective factors in judging the number and distribution of particles, especially when it is required to read the test results quickly within 5 seconds.

BGD 246 Intelligent Fineness of Grind Gauges is an intelligent instrument newly developed by our company. This instrument can not only automatically complete the standard scraping of the sample on the groove of the instrument, but also immediately take and save the pictures of the sample particles in the groove. And according to the regulations of the result reading of the relevant standards, it can automatically identify the scraper fineness value of the sample within 5 seconds, and also display the statistical chart of particle distribution.

The instrument can adapt to different specifications, types and sizes of fineness of grind gauges, and it is equipped with MODBUS TCP/RTU communication port. The data storage capacity is large, which can effectively solve the problem of poor repeatability and reproducibility of the results when the scraper fineness is detected in the current industry, and greatly improve the work efficiency.

② Cross Hatch Test Image Recognizer

Introduction: After the cross hatch test of the film, the traditional method is for the operator to identify the peeling area with his own naked eye and carry out the corresponding rating. Since it is difficult to accurately quantify the peeling with the naked eye, there are relatively large subjective differences in the results or ratings, and it is easy to dispute. In order to solve this problem and improve the repeatability and reproducibility of the cross hatch test results, our company has developed an instrument that can automatically identify the peeling area. 

The instrument uses computer digital image processing (visual automatic analysis) technology to take photos of the crossed test panel, and then analyze and calculate the digital images, which can quickly and easily obtain accurate results.

BGD 350 Cross Hatch Test Image Recognizer is composed of a hand-held cylindrical structure, which can be conveniently placed on the cross hatch area pattern to be evaluated. It is also equipped with a camera and an LED lamp with adjustable illumination intensity.

③ Multifunction Wet Abrasion Scrub Tester With Image Recognition

Introduction: For the wet abrasion scrub of architectural coatings and related products, it is generally defined that the end point of the test is that the coating is abraded to a certain length: the inner wall coating is exposed in the 100mm coating area in the middle of the test panel, and the outer wall coating and ASTM 2486 method are that the damaged length exceeds the shim width (12.7mm). To accurately determine the end point of the test, it is not only necessary for the operator to have a preliminary prediction of the wet abrasion scrub times of the test samples, but also for them to be able to accurately identify the length of the abraded coating. However, it is quite difficult in actual operation.

BGD 528/S Multifunction Wet Abrasion Scrub Tester 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.

◆ Microsoft surface is used as the control computer, equipped with a 10.5-inch touch screen, which can display clearly and run smoothly.
