A brief introduction to the application skills of coating thickness gauges in various fields
Cars are closely related to our lives, and coating thickness gauges also play an important role in the automotive industry. As we all know, the thickness of car paint is related to the quality of the car itself. Especially when buying a second-hand car, uneven paint thickness may mean that the car has been repainted after impact wear, and the overall safety will be greatly reduced. The coating thickness gauge can detect the thickness of non-magnetic coatings on magnetic metal substrates such as steel. It can naturally be used to detect the thickness of coating paint on cars. In addition, chrome plating of molds, hard chrome plating of rollers, chrome plating of car exterior surfaces and accessories Galvanizing, etc. all require the detection of coating thickness, so that the workpiece can be more effectively protected, and the results are accurate and objective.
Coating thickness gauges are also widely used in the manufacturing of steel structure products. The main quality inspection links are inseparable from it, such as bridges, brackets, iron towers, ship plates including common road guardrails, etc., as well as printed circuit boards, and For screen printing, coating thickness gauges can be used to efficiently and accurately measure non-conductive coatings such as paint, varnish, enamel, chrome, and galvanized coatings, which has become a must for these manufacturers.
Not only the steel structure, but the development of aluminum enterprises has entered a new stage. The coating thickness gauge is also of inestimable value for the aluminum profile industry. The key is to detect the oxide film on the outer surface of the aluminum profile. The maintenance of the oxide film is the most important It is very important, which means that the coating thickness gauge is indispensable. Through accurate measurement, not only the product quality parameters can be obtained in time, but also the material can be saved. Relevant national policies also stipulate that the coating thickness gauge must be equipped in the steel factory such testing equipment.
Avoiding pipeline erosion is an important part of pipeline engineering. Proper treatment of the outer surface of the pipeline can prevent the occurrence of corrosion. The specific methods include spraying paint, anti-corrosion layer, powder layer, etc. The coating thickness gauge is used to test whether the coating on the outer wall of the pipeline meets the national standard, so as to judge whether the pipeline construction meets the standard. The oil and energy industry needs to use pipelines for transportation for a long time. Once the coating is not up to standard and leaks, it will bring huge economic losses. It is imperative to do a good job of testing. Therefore, the purpose of the coating thickness gauge is of great significance.
To sum up, in chemical industry, electronics, electric power, metal and other industries, coating thickness measurement is a necessary and important process for quality inspection in metal processing industry, and it is an effective way for products to reach high-quality specifications. Coating measurement Houyi perfectly handles these situations and fully improves the manufacturing efficiency. It is a good assistant for manufacturers.
How to properly maintain the ultrasonic thickness gauge
The correct use of ultrasonic thickness gauge is very important to prolong the service life of the equipment, and the correct use includes the maintenance of the instrument.
Since the random test block is used to test the instrument, coupling agent needs to be applied, so please pay attention to rust prevention. Wipe the random test piece clean after use. Don't get sweaty when the temperature is high. If it is not used for a long time, a little oil should be applied on the surface of the random test block to prevent rust. When it is used again, wipe off the oil and then it can work normally.
Cleaning of the case, alcohol, diluent, etc. have a corrosive effect on the case, especially the window, so when cleaning, just wipe it gently with a small amount of water; for the protection of the probe, the probe table is very sensitive to redrawing on the rough surface, so in Press gently during use. When measuring rough surfaces, try to minimize the scratching of the probe on the working surface.
When measuring at room temperature, the surface of the measured object should not exceed 60°C, otherwise the probe can no longer be used. The adhesion of oil and dust will cause the probe cable to age and break gradually, and the dirt on the cable should be removed after use.
battery replacement
After the low voltage indicator appears, the battery should be replaced in time, as follows:
a. shutdown
b. Open the battery cover
c. Take out the battery and put in a new battery, pay attention to the polarity
When the instrument is not in use for a long time, the battery should be taken out to avoid battery leakage and corrosion of the battery case and pole pieces. Damaged Ultrasonic Thickness Gauge
Strictly avoid collision, moisture, etc.
