Q: How to choose high-temperature resistance cotton conveyor belt?
A: The current types of canvas conveyor belt is substantially the following: mixed woven cotton canvas, cotton canvas polypropylene filament, polyester filament cotton canvas, high and low stretch yarn canvas. In the above four categories of the canvas, the polyester filament polyester mixed woven cotton canvas and canvas comprehensive quality is the best. But in contrast to thermal aging and adhesion of polyester filament cotton canvas is better than ordinary cotton canvas, aging 200 ℃ 45 minutes and cotton interwoven canvas by the intensity decrease rate of around 30%, polyester mix woven canvas strength decreased rate of about 4%; weight sulfur in three experiments overall strength and elongation rate of decline decreased rates are far below the mixed woven cotton canvas, but also slightly higher than the adhesion strength polyester mixed weaving cotton canvas, so we prefer better polyester filament cotton canvas for resistant conveyor belt skeleton layer.
