With the rise of our country's economy and state, our country's highway traffic has also entered a period of rapid development, with the growth of all kinds of road repair. Under this background, many asphalt pavement thermal regeneration repair equipments with high technological content emerged. The hot air asphalt regeneration repair vehicle for asphalt pavement directly heats the asphalt pavement and repairs it with the original asphalt mixture. Advantages of hot-air regenerative repair vehicles 1. The hot air stove of the independent heating system directly connects the heating device, the intermediate link is greatly reduced, and the heating furnace can be started at any time as required, convenient, fast, and energy-saving. 2. The structure of the asphalt pavement heating wall is simple, light weight, left and right two heating boxes are equipped with separate heating wall hot blast stove. According to the size of the damaged area of ​​the road, the number of hot blast stoves on the heating wall can be flexibly controlled and started. The heating speed is fast, energy consumption is reduced, heat loss is reduced, and work efficiency is high. Hot air furnace work process The feeding device loads the bituminous concrete recovered from the road surface into the asphalt concrete heating and regenerating device. When the asphalt concrete needs to be heated, the electronic control system instructs the combustion controller on the hot stove to start the hot blast stove. The hot air generated in the hot blast stove is forcibly delivered to the asphalt concrete heating hot air ejector, and the hot air is directly sprayed onto the asphalt concrete located below the asphalt concrete heating and regenerating device by the oblique jet nozzle on the asphalt concrete heating hot air ejector. Fast, high heat utilization. 2. Work process of a heated wall stove When the asphalt pavement heating wall needs to work, the control system instructs the combustion controller on the heating wall hot blast furnace so that the heating wall hot blast furnace starts working. The hot air is forced through the outlet of the hot blast stove to the heated wall hot air jet and then jetted directly onto the asphalt pavement. At this moment, the asphalt pavement heating wall heats the ground at the most suitable distance. The air inlet on the blower connected with the heating wall cover sucks the hot air in the heating wall hood and sends it back to the outlet of the hot blast stove to form an asphalt road surface. Heating wall hot air circulation system to avoid the loss of heat. Redispersible Polymer Powder,RDP Powder,Redispersible Polyvinyl Acetate Emulsion Powder HENAN JINHE INDUSTRY CO.,LTD , https://www.speciatyelement.com
The re-dispersible polymer powder products are water-soluble re-dispersible powders, which are divided into copolymers of ethylene/vinyl acetate, copolymers of vinyl acetate/ethylene terephthalate, and acrylic ACID copolymers, etc. They are powder adhesives made by spray-drying and protected by polyvinyl alcohol. This powder can be quickly re-dispersed into a liquid when in contact with water. Due to the high adhesion capacity and unique properties of re-dispersible polymer powders, such as water resistance, workability, and thermal insulation, their application range is extremely broad. it can re-disperse in water and form a film after water evaporation by coalescence of individual polymer particles. The film acts as an organic binder to glue together different substrates, reinforce mortar structure and provide excellent adhesion at cement or gypsum based dry mixed mortar substrate interface. It has extremely outstanding adhesion strength, improves the flexibility of mortar and has a longer open time, giving the mortar excellent alkali resistance, improving the mortar's adhesion, cohesion, flexural strength, waterproofing, plasticity, wear resistance, and workability, in addition, it has stronger flexibility in flexible crack-resistant mortar.
