Introduction:
I. Overview of the sag tester
When the paint is applied to the vertical surface of the object, the paint flows downward before the paint is dried, causing the film thickness to be uneven and the phenomenon of "tear marks" to be sag. The morbidity caused by the paint during the construction and drying process not only makes the paint film look bad, but also affects the protective performance of the paint film. Therefore, the QAG type paint sagability tester designed and manufactured according to the GB9264-88 standard can be used for simple comparison test of the dispersion and sag properties of the paint during construction and drying, thereby adjusting the formulation or construction of the paint. Optimum thickness.
The measuring instrument is a special test instrument, which can quickly check whether the product is qualified or not, can give the best color paint construction thickness, save time and save construction costs. And the instrument is made of tool steel, which is wear-resistant and easy to clean.
Second, the sagability tester range of centrifuges
This tester is suitable for determining the relative sagability test of paints. This tester is not suitable for the sag test of varnish and powder coatings.
So how do you choose the right sag meter? Let's briefly discuss it below.
It is well known that the thickness of the paint film is mostly around 0.5-1 mm. Too thick will cause the surface of the coating to be too thick and thick, affecting the appearance and use. Therefore, the range selection of the sag tester will have a great impact on the detection of the sample. Several mainstream sagmeters in the market have measurement ranges of around 0.02-1mm. When the conductivity meter is not the larger the range, the better. A coating of about 1 mm is already thicker, but the larger the range, the lower the corresponding accuracy, and most 0.1-0.8 can meet the requirements of sample measurement.
The sag-testing leveling instrument uses the sag test of the paint film coating in the groove. Therefore, the number of grooves in a sag can directly determine the amount of sample that can be simultaneously measured. At the same time, more grooves can also make multiple samples for simultaneous test comparison, which can easily and intuitively see the difference between each sample. The SY series sag tester produced in Beijing has 5 grooves, and 5 kinds of samples are measured at the same time to make them popular in the market, which has become the focus of the majority of customers. The spacing of the DIN cup film is also a factor that cannot be ignored. If the sample spacing is too large, it is inconvenient to observe compared to the disperser. If the sample spacing is too small, it is easy to get close to each other. The sample spacing is preferably around 1 mm. Of course, the more the grooves, the larger the spacing is.
