Overview
OSP-22 L2000φ 16 formed wire coating bar is a professional Spreader tool produced by the Japanese OSP brand. It is manufactured by extrusion process, made of 304 stainless steel, and has a chrome-plated surface. The product is specially designed to replace the traditional steel wire coating bar. It can precisely control the wet film thickness as low as 1.5 μm to achieve ultra-thin Spreader. It is widely used in Spreader processes in film, Glass, paper and other industries.
Features
1. Made by extrusion process to avoid the common steel wire loosening and disconnection problems of traditional steel wire coating bars
2. The bottom of the groove is designed to be wider, which is larger than the traditional steel wire coating bar Coating Weight
3. Surface chrome plating, easy to clean, not easy to clog
4. Accurate control of wet film thickness to 1.5μm for ultra-thin Spreader
5. Specifications and lengths can be customized to meet different production needs
Principle
Spreader liquid on the surface of the substrate, using D-Bar formed wire coating bar to adjust and scrape off the amount of excess liquid, through its special groove design control Spreader thickness, to achieve accurate Spreader effect.
Applications
Film: LCD film, X-ray film, Encasement film, etc., Glass: Automotive Glass, LCD Glass, Construction Glass, etc., Paper: Newspaper, Light Paper, Wallpaper, Special Paper, etc., Encasement Material: Carton, Tape, Encasement Paper, etc., Tape: Video Tape, etc., Magnetic Card: Ticket, Recharge Card, etc
Steps
1. Spreader liquid on substrate surface
2. Use D-Bar formed wire coating bar to scrape Spreader surface
3. Adjust and remove excess liquid by coating bar
4. Complete Spreader Thickness Control
