Overview
YONGCHAOMT D10-YC010-L400mm Experimental Spreader Metering rod is a long bar manufactured by an innovative process. It uses precision die cold extrusion technology to process wavy Linear dispersion on the surface of the steel rod, replacing the traditional way of winding steel wire, effectively solving the problem that the steel wire is easy to loose and difficult to clean, and can realize ultra-thin film Spreader. The surface of the wire rod is plated with high hardness hard chrome, which is wear-resistant and durable. The total length is 400mm, and the effective Spreader width is 310mm.
Features
1. Using cold extrusion technology to process surface wavy Linear dispersion, without traditional winding steel wire, to prevent the risk of steel wire loosening or fracture.
2. Linear dispersion on the surface is smooth and smooth, easy to clean thoroughly.
3. The surface is plated with hard chromium with hardness up to 1300HV, which greatly improves Abrasion Resistance and service life.
4. Ultra-thin film Spreader can be realized to meet the needs of precision experiments.
5. Made of 304 stainless steel, it is sturdy and durable.
Principle
The Metering rod transfers and controls the Spreader fluid using the precise irregularities and wavy Linear dispersion formed on its surface by cold extrusion technology. During the Spreader process, the rod body rolls or scrapes on the surface of the substrate, and the surface Linear dispersion structure can precisely define and leave a wet-film of a specific Film thickness. The principle is the same as the traditional wire-wound drawdown bar, but the structure is more stable and accurate.
Applications
Lab Spreaders, Coatings R & D, inks Testing, Adhesive Spreaders, Precision Film prepatives
Steps
1. According to the required wet film thickness, refer to the model selection table to select the appropriate bar model.
2. Ensure that the bar and the surface of the substrate to be Spreader are clean.
3. Place an appropriate amount of Spreader liquid on the front end of the substrate.
4. Hold both ends of the bar (45mm in each hand width) and roll or scrape on the substrate with uniform speed and pressure.
5. After the Spreader is completed, use the appropriate solvent to clean the bar surface in time.
Notice
• Please check the wet film thickness corresponding to the model before use to ensure correct selection.
• When operating, please hold the designated areas at both ends and avoid touching the Spreader area.
• Wash thoroughly immediately after use to prevent Spreader from drying up and clogging the surface Linear dispersion.
• When cleaning, it is recommended to use a soft cloth and a suitable solvent to avoid scratching the surface with hard objects.
Store in a drying place to avoid bumping to protect surface platings and precision structures.
