Rubber speed bump is also called rubber deceleration ridge. It is a traffic facility installed on the road to slow down passing vehicles. It is generally strip-shaped or dot-shaped. The material is mainly rubber or metal. It is generally yellow and black. It attracts visual attention and makes the road surface slightly arched to achieve the purpose of vehicle deceleration. It is generally installed on highway crossings, industrial and mining enterprises, schools, residential quarter entrances, etc., where vehicles need to slow down and road sections that are prone to traffic accidents. It is used for reducers. New traffic-specific safety settings for the speed of motor vehicles and non-motor vehicles. The speed bump has greatly reduced the occurrence of accidents at major traffic intersections, and is a new type of special facility for traffic safety. The vehicle is not only safe but also serves the purpose of buffering and decelerating during driving, so as to improve the safety of traffic crossings.
Manufacturing process of ubber speed bump
Mixing process
Mixing refers to the process of uniformly mixing various compounding ingredients into raw rubber on the rubber mixer. The quality of mixing has a decisive influence on the further processing of the rubber and the quality of the finished product. Even if the rubber is well formulated, if the mixing is not good, there will be uneven dispersion of the compounding agent, and the plasticity of the rubber is too high. Or if it is too low, it is easy to burn, bloom, etc., so that the processes of calendering, pressing, gluing and vulcanization cannot be carried out normally, and it will also lead to a decline in product performance. The rubber speed bump adopts the mixing method, which is currently the most widely used method in the rubber industry.
Calendering process
Calendering is the process of making rubber into a film on a calender or a semi-finished tape with a skeleton material, which includes operations such as sheet pressing, lamination, pressing, and textile gluing. The rubber speed bump calendering process generally includes the following processes: preheating and supplying of the rubber compound; opening and drying of the textile (and sometimes dipping).
Extrusion process
The extrusion process is through the action of the barrel wall of the extruder and the screw parts to make the rubber material achieve the purpose of extrusion and preliminary shape, and the extrusion process is also called an extrusion process. The main equipment of the extrusion process is the extruder. Rubber speed bumps belong to recycled rubber speed bumps, with fast extrusion speed and small shrinkage rate of semi-finished products.
