Overview
The wire scraper produced by RDS company adopts the Mayer-Bar principle to control the wet film thickness through the diameter of the wire, which is widely used in more than 50 sub-industries in China. The scraper has been well used in the surface film test of coatings, inks, varnishes and various machinery manufacturing industries. In recent years, it has also been used as a common scraping sample instrument in the fields of **, biology and other fields. This product mainly coalescence has the mainstream 3/8 inch diameter wire scraper in China to facilitate users to place orders and purchase.
Features
1. Using the Mayer-Bar principle, the wet film thickness is precisely controlled by the diameter of the wire.
2. The production process is wire-wound, and according to the brand data, its wire breakage rate is low.
3. The rod body is made of stainless steel for good durability.
4. Uniform specifications, Spreader width of 300mm, easy to standardize operation.
Principle
The wire scraper works based on the Mayer-Bar principle. Its core is to control the film thickness of the wet-film after the Spreader by the diameter of the precision steel wire wound on the rod body. When the scraper scrapes on the substrate, the excess paint or inks are blocked and carried away by the steel wire, thereby leaving a wet-film layer with uniform Film thickness and determined by the diameter of the steel wire on the surface of the coated object.
Applications
Coatings, inks, varnishes, mechanical manufacturing, surface film testing, **, biological
Steps
1. Place the paint or inks to be tested on one end of the substrate.
2. Hold both ends of the scraper and place the wire side of the scraper smoothly in front of the paint.
3. At a uniform speed and appropriate pressure, the wiper is pulled in the direction of the body to spread the film formation on the substrate.
4. After the scraping is completed, check and evaluate the formed wet-film.
Notice
• When using, avoid bumping the scraper, especially the steel wire part, to prevent damage.
• Maintain uniform speed and pressure during scraping to ensure consistent film Film thickness.
• Scraper is a precision consumable. After long-term use, the steel wire will be abrasion, which will affect the accuracy of Spreader. It needs to be checked regularly and replaced in time according to the actual frequency of use and abrasion.
• Do not intentionally damage or improperly use the scraper.
