Small-Sized Asphalt Waterproofing Membrane Equipment

Small-Sized Asphalt Waterproofing Membrane Equipment is a professional equipment used to produce asphalt waterproofing membrane. The following is its related introduction:

Main equipment composition

Asphalt storage and supply system: including asphalt storage tanks, heating devices, delivery pumps, etc. It is used to store and heat asphalt to keep it in a suitable flow state so that it can be evenly coated on the tire base cloth later.

Tire base cloth delivery device: responsible for smoothly conveying the tire base cloth (such as polyester tire, glass fiber tire, etc.) to each station of the production line at the set speed and tension to ensure the stable supply of the base material of the coil.

Coating system: composed of asphalt extruder, oiling head or scraper, etc. The heated asphalt is evenly coated on the tire base cloth, and the coating thickness and uniformity are controlled to ensure the waterproof performance of the coil.

Spreading device: used to spread isolation materials such as talcum powder, fine sand, etc. on the tire base cloth coated with asphalt to prevent the coil from sticking during storage and use, and at the same time increase the anti-slip performance and wear resistance of the coil.

Cooling system: usually water cooling or air cooling is used to quickly cool the coiled material after asphalt coating, so that the asphalt layer is solidified and formed, which is convenient for the subsequent winding and packaging process 1.

Traction and reeling device: The traction device provides the pulling force during the coil production process to ensure the stable transmission of the coil between each station; the reeling device will neatly reel up the produced asphalt coil for easy storage and transportation.

Production process

Preparation of tire base cloth: Place the rolled tire base cloth on the unwinding device, adjust the tension and position so that it can smoothly enter the production line.

Asphalt heating and coating: The asphalt is heated to a flowing state in the storage tank and transported to the coating system through the delivery pump. The extruder extrude the asphalt evenly, and the oiling head or scraper evenly coats the asphalt on the tire base cloth to form an asphalt layer of a certain thickness.

Spreading isolation material: On the tire base cloth coated with asphalt, the spreading device evenly sprinkles isolation material, such as talcum powder or fine sand, to prevent the coil from sticking.

Cooling and shaping: The coil coated with asphalt and sprinkled with isolation material enters the cooling system, and the asphalt is quickly cooled and solidified by water cooling or air cooling, and the coil is shaped.

Traction and reeling: The coiled material after cooling and shaping is towed by the traction device and transmitted to the reeling device at a stable speed. The reeling device reels the coiled material neatly into a roll to complete the production process.

Technology development trend

Automation and intelligence: Use advanced automation control systems to realize automated operation and monitoring of the production process, improve production efficiency, product quality stability, and reduce labor costs and labor intensity. For example, through PLC touch screen control, accurate control and parameter adjustment of each device, as well as real-time collection and analysis of production data can be achieved. 5.

Energy saving and environmental protection: Use more efficient energy-saving heating technology in heating methods to reduce energy consumption; optimize the cooling process in the cooling system, improve cooling efficiency, and reduce water resource consumption; at the same time, effectively treat waste gas and wastewater in the production process to reduce pollution to the environment.

Product quality improvement: Improve the uniformity and thickness accuracy of asphalt coating by improving coating technology and equipment; optimize the spreading device to ensure uniform spreading of isolation materials; use high-precision traction and reeling systems to improve the flatness and reeling quality of the coiled material, thereby producing higher quality asphalt coiled materials.

Multifunctional and customized: It can produce various types and specifications of asphalt membranes to meet the needs of different customers; it can also develop asphalt membrane production lines with special functions according to market demand, such as production lines for self-adhesive modified asphalt waterproof membranes and root-penetration-resistant asphalt waterproof membranes.

Application areas

Building waterproofing: It is widely used in waterproofing projects of roofs, basements, toilets, exterior walls and other parts of various buildings to prevent rainwater, groundwater and other moisture from penetrating into the interior of the building, and protect the building structure and internal facilities from water erosion.

Road engineering: It is used for waterproofing and moisture-proofing of roads, such as waterproofing of the road base of highways and urban roads, as well as waterproofing projects of structures such as bridges and tunnels, to extend the service life of roads and improve the durability and safety of roads.

Water conservancy projects: It is used to prevent water leakage in water conservancy facilities such as reservoirs, dams, and canals, to ensure the normal operation of water conservancy projects and the effective use of water resources.
