        Detailed introduction
        
                            Ultra-wide conveyor belts are now a trend in transportation in various industries. The method of increasing the width can be used to improve the transportation efficiency, and the transportation volume requirements are relatively high. Reduce transportation costs. At present, ultra-wide belt, ultra-wide wire rope core ultra-wide conveyor belt, ultra-wide pattern ultra-wide conveyor belt and ultra-wide filter tape and other special-shaped products. The ultra-wide conveyor belt is made of high quality and high wear resistance Malaysian natural rubber, with high wear resistance and long service life. Help large plants such as steel plants and power plants to conduct rapid material selection. In addition, the internal fabric layer is made of transport and tear resistant nylon fabric layer, which can provide ultra-broadband in the transportation of continuous power. At present, the rubber ultra-wide conveyor belt is developing towards high performance, light weight, energy saving, environmental protection, safety and other aspects, and the environmental protection requirements are becoming more and more stringent, so the selection of raw materials for the rubber ultra-wide conveyor belt must be careful. In the actual production and application process, the rubber ultra-wide conveyor belt covering rubber is a key part that determines the performance and use of the belt body.
        

        
	 

        
So what rubber raw materials should be selected for ordinary environment-friendly ultra-wide conveyor belt covering glue? Which rubber compounds are better matched? 1. Environment-friendly ultra-wide conveyor belt covered with rubber raw materials Under normal circumstances, the ordinary environment-friendly ultra-wide conveyor belt covered with natural rubber or styrene-butadiene rubber as the main raw material, or natural rubber/styrene-butadiene rubber combined. Natural rubber has high mechanical strength, good elasticity, and better heat, wear and aging resistance of styrene butadiene rubber; Natural rubber/styrene-butadiene rubber combined with good mechanical properties, heat resistance, aging resistance. In actual production, rubber lining products manufacturers can also use environmentally friendly recycled rubber in natural rubber, styrene-butadiene rubber or natural rubber/styrene-butadiene rubber and use appropriate amounts of rubber to reduce costs. The general environment-friendly ultra-wide conveyor belt vulcanization system generally chooses the traditional sulfur vulcanization system, with the use of appropriate varieties of accelerators, zinc oxide and stearic acid synergistic effect to further improve the vulcanization efficiency and prevent burning. The reinforcing system is carbon black 2LLYY1210WFM, and the reinforcing resin can be used in appropriate amount if necessary. The ultra-wide conveyor belt with certain demand for flame retardant performance can be used with chemical flame retardants and inorganic magnesium hydroxide, and zinc hydroxide is an environmentally friendly filled flame retardant. Chemical antioxidant combined with paraffin can effectively delay the aging time of environmental protection super wide conveyor belt. Natural rubber 55 parts, styrene butadiene rubber 45 parts, sulfur 1.6 parts, accelerator 1.2 parts, zinc oxide 7 parts, stearic acid 5 parts, antioxidant 3.5 parts, paraffin 1 part, environmental protection flame retardant 17.5 parts, magnesium hydroxide 6 parts, reinforced resin 15 parts, carbon black 45 parts; Total: 202.8 copies. The production formula of ordinary environment-friendly ultra-wide conveyor belt covering adhesive can use rubber softener and plasticizer appropriately according to the performance and processing needs. In the production process of ordinary environmental protection ultra-wide conveyor belt, it is necessary to consider the environmental protection of raw materials and whether various compounding agents will react with each other to produce polluting substances. When recycled rubber is used to reduce the raw material cost of ordinary environmentally friendly ultra-wide conveyor belt covering rubber, manufacturers of ultra-wide conveyor belt need to choose environmentally friendly recycled rubber, appropriately adjust the reference formula of ultra-wide conveyor belt covering rubber, reduce costs and optimize the quality of ultra-wide conveyor belt. Xiaobian has the opportunity to continue to share with you the selection of raw materials and formula design of other rubber layers of ordinary environmental protection ultra-wide conveyor belt.
