In the new material industry, it is often necessary to use a wire Bar Coater ( also known as a coating bar, a scraper bar, a Meller bar, etc. ) to perform coating sample preparation to prepare a specific film thickness coating for material performance testing experiments. This article is a encyclopedia of new material experimental coating technology, which summarizes the relevant technical knowledge standards for coating proofing, selection of wire rod coaters, common problems in coating, and commonly used wire rod brands in the new material industry.
How to choose the wire rod?
To choose a suitable wire rod coater, you can start from five aspects, including brand, wet film thickness, production process, main rod diameter, and coating film width. Based on years of wire rod sales experience and the analysis and summary of big data purchased by users in the industry market, NBCHAO Mall has summarized a detailed selection idea :
Production process: wire winding type | extrusion type Wet film thickness: 0-10um | 11-20um | 21-50um | 51-100um | above 101um Diameter: 6.35mm | 9.52mm | 10mm | 12.7mm | 16mm | Others Coating width: below 10cm | 11-30cm | above 30cm Handle adaptation: yes | no |
* * Wire Bar Coater is an experimental instrument for preparing coating film. The wet film thickness required by the experiment is an important selection factor for the wire bar. However, some users often do not know the wet film thickness required by the experiment, but only know the coating amount. , solid content and other parameters. For this reason, NBCHAO Mall has developed a " Wet Film Thickness Calculator " for users to use for free to help them better select models.
