Zhongbo has been adopting high strength canvas conveyor belt, which is mainly characterized in that the bending degree of weft yarn is obviously lower than ordinary plain canvas, so it can only be used for the production of single or double conveyor belt, roller diameter or must increase the conveyor belt, or will soon delamination. With a single or double high strength canvas conveyor belt has the following obvious advantages. (1) strength and high utilization rate Straight direction warp and stress direction is completely consistent, warp strength utilization rate reached the highest, and in the same level of belt conveying production, skeleton material consumption can be reduced, thus reducing the cost of. (2)advantages of simple production process Layer reduction can be simple production process of conveying belt. For example, the production of 1000N/4, and then paste molding, and fabric width inconsistent or bad shape cause conveyor belt wide differences, son to take high light canvas need only rolling again, again under the cover can be attached to the upper. (3) the conveyor belt more stable quality The multilayer structure, the difference will cause the conveyer belt fatigue decreased, which is often the skeleton material incoming inspection, but the main reason the finished belt strength but not qualified. The skeleton material rolling and molding temperature, tension or small differences will result in differences framework material layer, cotton acrylic canvas also due to moisture absorption rate, relaxation balance of different differences. The monolayer structure belt completely eliminates these problems, can improve the performance and quality of conveying belt. (4) good dimensional stability The warp is always in the state of extension, does not have the spring effect, therefore the elongation decreases greatly, the load elongation straight weft EP canvas reach below 0.5%, so the conveyor belt has good dimensional stability, single-layer structure belt body thin, small quality, especially suitable for long distance conveying belt. Foreign EP but not of constant load elongation is more than the domestic EP canvas, the main reason is that foreign EP canvas warp crimp at around 5%, only 2.5% of domestic. (5) It can reduce the conveyor roller diameter and length of the requirements. High light canvas conveyor belt can reduce the conveyor roller diameter and tensioning length requirements, in use can reduce the periodic tension maintenance. (6) good anti impact performance High light canvas, especially the high strength canvas backed weave, the weft density can be more than ordinary plain canvas is high, and the weft more crude, at the same time as the weft is in the state of extension, under the action of external force, the weft can immediately stress stretch, will force rapid lateral diffusion, the external force can be buffered, so it has excellent impact performance. (7)It can be made of high modulus material High modulus fiber new material, such as aramid fiber, glass fiber, must use the diameter structure and can only be used for transporting dangerous monolayer structure belt. The more high modulus materials, in the roller more prone to compression, material is easy to fatigue damage, resulting in loss of strength is greatly improved, the service life is greatly reduced. (8) To overcome some defects of cotton fiber The improvement can improve cotton fiber canvas low modulus, elongation of the disadvantages of easy fabric warp straight degree. To obtain the widespread application which has been in the cotton fibers resource rich countries from the former Soviet Union. Visible, the conveyor belt of high strength single layer has many advantages in multilayer conveyor belt incomparable. In foreign countries, this kind of conveyor belt conveyor belt has accounted for more than 30% of the total, in the developed countries is wider, so I put this high-strength conveyor belt canvas as a weapon to open up the international market, and continuously access to trust and praise of customers, firmly on the international stage more dance more wonderful | |||
