Mayer-rod is a commonly used paint measuring Rod, also known as Mayer scraper. It is mainly used to control the thickness of coating materials such as coatings, inks and adhesives. The paint metering rod is made of metal, has a smooth surface and is easy to clean, enabling accurate and uniform coating.

The paint measuring rod is characterized by a series of equidistant transverse grooves on its surface, and the size and spacing of these grooves determine the thickness of the paint. When the paint passes through the paint metering rod, the paint fills into the groove, forming a coating of a certain thickness. By adjusting the size and spacing of the grooves, coatings of different thicknesses can be achieved.

advantage
The paint measuring rod has the following advantages:

High accuracy: Accurate coating thickness control can be achieved, reducing paint waste and reducing production costs.

Uniform coating: The design of the paint metering rod allows the paint to be evenly distributed on the surface of the substrate, improving the coating quality. This is especially important for coatings that require a high degree of consistency, such as automotive, electronic equipment and other industries.

Easy to clean: The rod has a smooth surface for easy cleaning and keeping clean. This helps reduce paint residue and cross-contamination and ensures coating quality.

Strong adjustable: The groove size and spacing of the coating measuring rod can be adjusted according to different coating requirements and process conditions, so that it has strong adaptability and flexibility.

Wide range of application: the coating measuring rod can be used in a variety of coatings, inks, adhesives and other coating processes, including paper, plastic film, metal plate, textile and other substrates.

defect
However, the paint metering rod also has some limitations, such as it may not be effective in high-viscosity coatings and high-thickness coating applications. Therefore, in practical applications, it is necessary to select the appropriate coating measuring rod according to the specific coating requirements. In order to overcome the limitations of paint metering sticks in some cases, the paint industry has also adopted other types of paint metering sticks. Here are some common paint measuring sticks and their applications:

Linear scraper: Linear scraper is a simple and practical paint measuring stick. It uses a straight metal rod to control the coating thickness by adjusting the clearance to the substrate surface. Linear scrapers are suitable for low-viscosity coating materials such as coatings, inks and adhesives, especially in thinner coating applications.

Rotary scraper: Rotary scraper is a paint metering rod that works by using a metal rod with a scraper to rotate at a certain speed and control the coating thickness through the contact between the scraper and the substrate surface. The rotary scraper is suitable for applications with high viscosity coatings and high thickness coatings, allowing for more uniform and effective coating.

Air gap scraper: The air gap scraper is a coating measuring stick that uses gas pressure to control the thickness of the coating. It is suitable for high viscosity coatings and high thickness coating applications, enabling accurate and uniform coating. The main advantage of the air gap scraper is that it can effectively reduce the waste of paint and reduce production costs.

Magnetic scraper: Magnetic scraper is a coating measuring rod that uses magnetic force to control the thickness of the coating. It is suitable for high viscosity coatings and high thickness coating applications, enabling accurate and uniform coating. The main advantage of magnetic scraper is that it can effectively reduce the waste of paint and reduce production costs.

These paint metering rods play a key role in the application of the paint industry. By selecting the appropriate coating measuring rod, the coating quality can be effectively improved, the production cost can be reduced, and the coating requirements of different industries and products can be met. In practical applications, it is necessary to select the appropriate coating measuring rod according to the properties of the coating, the thickness of the coating, the type of the substrate and other factors to achieve better coating effects.

Key points of selection

When choosing and using paint metering rods, there are several key factors to consider to ensure better coating results:

Coating properties: Factors such as viscosity, fluidity and drying speed of the coating will affect the selection of the coating measuring rod. For example, for high viscosity coatings, a rotary scraper, an air gap scraper, or a magnetic scraper may be more suitable than a paint metering stick.

Coating thickness: Coating thickness also has a great impact on the selection of paint metering rods. Thinner coatings may be better suited with a linear scraper or paint metering stick, while thicker coatings may require the use of a rotary scraper, an air gap scraper, or a magnetic scraper.

Substrate type: Different substrates also have an impact on the selection of paint metering rods. For example, for sheet metal or plastic film, the coating metering rod needs to have good wear resistance; For flexible substrates such as paper or textiles, the paint metering rod needs to have good flexibility.

Production speed: Paint metering rods need to be able to adapt to the speed of the production line. On high-speed production lines, paint metering rods such as rotary scrapers or air gap scrapers that enable rapid application may be more suitable.

Cleaning and maintenance: Paint metering rods need to be easy to clean and maintain to ensure coating quality and productivity. For example, paint metering rods and linear scrapers are relatively easy to clean due to their smooth surfaces.

In short, the paint measuring rod plays a very important role in the paint industry. The correct selection and use of coating metering rods can greatly improve coating quality, reduce production costs, and meet the needs of various coating applications. In actual production, the appropriate coating measuring rod should be selected according to the characteristics of the coating, the thickness of the coating, the type of the substrate and other factors to ensure a better coating effect. At the same time, the correct use and maintenance of the paint measuring rod is also the key to improve production efficiency and coating quality.
