Belt conveyor transportation is an important symbol of the industrialization of the country. It has the incomparable advantages of other transportation methods, such as continuity, high efficiency and low cost. The greater the degree of industrialization in a country, the greater the proportion of industrial transportation.It is good at the service life of belt conveyor rollers.
At present, China’s new large mines, modern port, a large power station, opencast coal mine conveying system mostly adopts high strength flame retardant conveyor belt, however, in the north of China, especially the vast area of more than 40 degrees north latitude, the existing general retardant conveyor belt can not adapt to the climate there, in winter, the environment temperature down to below 20 DEG C, the tape will harden, skid, cover the surface cracking, fracture or even scrap tape, seriously affect the smooth production.
Therefore, some key projects in northern China, Northwest China and other places urgently need high strength, suitable for long distance, long distance transportation, flame retardant, cold resistant and high strength conveyor belts. It is imperative to develop flame retardant and cold resistant conveyor belt to solve the difficulty of material transportation in winter in large enterprises in northern china. In view of this situation, our factory decided to develop flame retardant and cold resistant conveyor belt.
The research and development of flame retardant and cold resistant conveyor belt will further expand the market competition ability of our factory in the vast areas of the north, fill the gap at home, and strengthen enterprises to explore the international market and expand export capacity.It is good at the service life of belt conveyor rollers.
The formulation of flame retardant and cold resistant conveyor belt is the key to develop the formulation of covering rubber. The utility model can be used normally under the condition of 40 DEG C, and has the electrostatic conducting property and the flame retardant performance. That is, to keep the conveyor belt in cold condition, no skid, no hard, no crack and safety performance, so that the operation is stable.Selection of rubber species, any rubber in the external environment, due to the temperature difference, there are glass, leather, rubber (see). General rubber at room temperature or higher environmental temperature, showing rubbery, to meet the general use requirements. In low temperature environments, such as in the frigid zone, they appear leather, even glassy.
The performance of low temperature of their various plasticizing agent and rubber modulus and temperature of the cold resistance of the rubber type on the compound plays an important role in determining the formulation system, so we first is a selection of cold resistant rubber flame retardant.It is good at the service life of belt conveyor rollers.
The quality of mixed rubber in mixing process has a decisive influence on the further processing and final product quality of rubber compound. Mix mixing is not good will appear with the agent are unevenly distributed, rubber plastic is too big or small, scorch, spray frost and other phenomena, can not make rolling vulcanization process directly affects the normal, cold and flame resistant properties of the product. Therefore, in addition to the raw materials for the factory inspection, strict implementation of standards, but also for certain varieties of screening agents, so that a variety of complexing agents can be evenly dispersed.
