Application of Coating Thickness Gauge in Water-Based Coating Industry
Water-based coatings are widely used in industry. So what is a water-based paint? All coatings that use water as a solvent or dispersion medium become water-based coatings. Water-based coatings are mainly divided into two categories, including natural mineral materials and synthetic resin-based water-based materials. Below we briefly talk about water-based synthetic resin.
1.The treatment and spraying of water-soluble materials
Synthetic resin-based water-soluble materials include water-based paints, water-reducible paints and water-dispersible paints. Water-soluble coatings are based on water-soluble resins. This material is non-sticky, durable and the construction process is very strict. Specific requirements and film thickness requirements are as follows:
(1) Material processing
Empty the metal substrate or clean it with a solvent to achieve the purpose of degreasing. The surface is then blasted. The thickness of the blasted sand measured by a coating thickness gauge is 2.0 μm-3.5 μm.
(2) Bottom coating spraying
The primer must be fully rolled for 120 revolutions before spraying to ensure that the material is clean, dry and free of any grease. Do not touch the matte surface with your hands, otherwise it will affect the adhesion of water-based materials and cause peeling of the paint film. After spraying the water-based material on the substrate surface, the thickness of the dry film was measured with a coating thickness gauge to be about 10 μm to 15 μm.
(3) Surface coating spraying
The surface-layer water-based coating must be rolled slowly for 100 revolutions before use and stir well. After the coated bottom workpiece is cooled to normal temperature, the surface construction can be performed. And the construction is performed under a certain pressure, distance, temperature and time. After construction, dry it by yourself. After drying, sintering and sintering, use a coating thickness gauge to measure the total thickness of the coating film from about 20 μm to 23 μm.
2.Measure the thickness of water-based coating with Linshang LS221 coating thickness gauge
The operation of Linshang LS221 coating thickness gauge is very simplewhen measuring water-based coatings. Long press the button, the instrument will display measurement modes, language, unit. Short press the power button to select. After selecting the measurement mode or language unit you need, wait for a moment, the selection will be conformed.

Press the probe vertically on the zero plate and press the button on the instrument. Raise the instrument up to 15cm according to the prompts. When 0.0 is displayed on the instrument, the zero adjustment is completed. The measurement can be started. Hold the position of the groove on the prone with your fingers and press the probe vertically on the surface of the measured object to measure the coating thickness of the measured object, which is very convenient to use.
Linshang LS221 coating thickness gauge adopts the split design, which can view the data while measuring in a complex test environment. This instrument ensures that it can pass the testing of Chinese national authoritative organizations,. The coating thickness gauge can quickly, non-destructively and accurately measure the thickness of coatings, which can be used in the laboratory and the construction site.
