Today, the demand for waterproofing materials is increasing. Whether it’s the severe requirements for roof and basement waterproofing in the construction field, the emphasis on preventing pollutant leaking in environmental protection water conservation projects, or the dependence on waterproofing functionality in many industries like agriculture and transportation, the production of high-performance waterproofing products has become essential. As cutting-edge equipment for manufacturing high-density waterproofing membranes, geomembranes, moisture-proof layers, and other products, the Waterproof Extrusion Line was developed and has become essential. It employs advanced multi-layer extrusion technology that is similar to the craftsman’s approach. Each layer of structure is created with care to ensure that the waterproofing membrane and other products produced have a superior waterproof capacity, have a strong tear strength, and are resistant to weather. It can adhere to its post in various adverse environments and provide long-lasting waterproofing. Let’s explore its unique beauty in greater detail.
Powerful technical abilities of the waterproof extrusion line
- Technology for multiple extrusion layers.
Waterproof extrusion line has a 2-5 5-layered composition that includes a reinforcing layer, a barrier layer, a wear-resistant layer, and so on. The reinforcement layer is similar to a solid skeleton, which increases the waterproof membrane’s strength, making it less likely that it will break during construction or utilization; the barrier layer is similar to a solid defense line, which effectively blocks the passage of moisture and gases, this further enhances the waterproof performance; the wear-resistant layer ensures that the product will maintain its effectiveness over time, even in the face of various frictions and wear. The layers function as a closely associated team, which increases the waterproof performance and mechanical properties of the waterproof membrane. Additionally, the high-precision pump that measures in meters is crucial to ensuring the uniform thickness of each layer. It’s similar to a precise “flow housekeeper” that can control the volume of material to a specific degree, ensuring that the thickness of each layer is within a small range of accuracy, with a maximum error of 5%, this will guarantee the quality of the waterproof membrane is consistent across the entire surface, whether it’s laid across a large area or utilized in special circumstances, it will provide effective waterproof protection. - Effective extrusion system
The barrier-style design of the barrier is the core of the equipment that facilitates uniform plasticization. Its peculiar design allows the plastic particles to surround the inner wall of the container under the motion of the screw, and to be subjected to a uniform force of shear and friction, this results in the uniform plasticization of the plastic. This uniform plasticization not only enhances the melting quality of the plastic but also causes the waterproof roll material to have a uniform texture and a consistent performance. Taking the HDPE material as an example, the capacity for production through the barrier design is 300-800kg/h, which is large enough for the production of large-scale quantities. The pump that melts plays a significant role as a pressure equalizer in the extrusion procedure. When the material is extruded to the mold in the extruder, the melt pump increases the pressure of the material through the rotation of the gears, this effectively prevents the material from flowing in the feed area and having a fluctuating pressure on the discharge area, which ensures the stability of the extrusion pressure and the deviation of the pressure is less than 1MPa. This facilitates the uniform thickness of the produced water-resistant roll, the quality is more consistent, and the number of defects caused by pressure fluctuations is decreased. - Adequate temperature regulation and cooling.
The multiple-stage independent temperature regulation technology enables the Waterproof Extrusion Line to precisely control the temperature of each section of the extruder according to the processing requirements of different materials, with a temperature accuracy of up to ±1℃. Different thermoplastics, such as HDPE, LDPE, PP, and PVC, have different requirements for temperature during processing. Through multiple stages of independent temperature control, the most effective processing temperature for each material can be determined, which will lead to the plasticizing effect and superior quality of the plastic. When processing PVC components, precise temperature control is possible, which will avoid the material’s decomposition caused by overzealous temperatures and will instead lead to a stable performance. The dual-sided cooling mechanism and air knife system serve as a single unit to achieve rapid design and prevent the waterproof rolls from deformation. The dual-sided cooling mechanism directly interacts with the roll and quickly dissipates heat via conduction. This leaves the roll with a quick cooling process and also eliminates moisture and impurities from the surface of the roll, which ensures the smoothness of the roll’s surface. This rapid prototyping method not only increases production efficiency but also avoids the deformation of the roll due to the uneven temperature of the cooling process. This method ensures the accuracy of the dimensions and appearance of the product. - Intelligent oversight and detection
The combination of PLC and a touch screen controller provides operators with an easy and intuitive way to operate. Through the touch screen, operators can easily establish various production parameters, such as the extrusion speed, temperature, pressure, etc., and can also observe the status of the equipment in real time. The equipment is also capable of storing multiple procedure formulas. When it is necessary to create waterproof membranes of different types or specifications, just name the appropriate formula, and the equipment will automatically adapt to the appropriate state of operation, which increases the flexibility and efficiency of the production process and decreases the probability of human error. The online thickness gauge employs β-X-ray technology, similar to a tireless “quality watch”, to measure the thickness of the waterproof membrane in real time with an accuracy of 0.01mm. Once the difference in thickness is detected to be greater than the established range, the system will immediately issue a warning and will automatically change the parameters of the equipment to make sure that the product’s thickness always satisfies the required standards. This function monitors the product quality in real-time and automatically adjusts it to ensure its stability, reduce the number of defects, and increase the efficiency of the enterprise’s production. - Environmental protection and energy-saving initiatives
The servo system that moves the water pump is the key to the line’s energy conservation. It can precisely regulate the speed and torque of the motor according to the specific requirements of the equipment, which prevents the waste of energy associated with the traditional system during operation. During the manufacturing process, when the equipment is required to lower production or alter the method of operation, the servo drive system can automatically decrease the speed of the motor, which will lead to a decrease in energy consumption of 20%-30%. The device that recovers the waste gases reflects the equipment’s dedication to environmental conservation. During the extrusion of plastic, some waste gases will be produced, these gases may contain harmful chemicals. The device for recovering waste gases collects and processes the gases through a specific technology of filtering and purifying. This technology reduces the pollution of the environment and supports green production for companies.

In greenhouses that are dedicated to agriculture, membranes that have multiple functions are crucial. These membranes are not only water-resistant but also have a drip and are resistant to ultraviolet light. The function that prevents droplets from forming due to the condensation of water vapor inside the greenhouse is called the drip-proof function. This function prevents damage to crops caused by ultraviolet light and extends the life of the greenhouse. In some instances, the cultivation of plants in greenhouses employs multifunctional membranes that promote the growth of plants and increase the yield and quality of the plants. In irrigation canals, the use of impermeable membranes can effectively inhibit the loss of water. By installing impermeable membranes that prevent water from reaching plants in the soil, the water transport efficiency can be increased, the utilization of water resources can be enhanced, and crops can be irrigated more effectively. In irrigated farmland in some arid regions, the utilization of impermeable membranes has a significant effect on the loss of water and the utilization of resources. This effect is especially pronounced in areas with a high concentration of water. - Transport and Urban Engineering

In road and railway projects that use geomembranes to isolate the groundwater, the purpose is to prevent the road from becoming softened due to the groundwater’s invasion, which would lead to a decrease in the stability and lifespan of the road. In the creation of some mountain roads, because of the high water table, the installation of geomembranes effectively isolates the water table, ensures the stability of the road bed, and decreases the likelihood of road disease. In subterranean pipe projects that are waterproof, membranes that are resistant to corrosion are employed to shield pipelines from the effects of chemicals in the groundwater and soil. These water-resistant membranes can form a solid barrier that extends the life of pipelines and guarantees the proper functioning of various pipelines in the pipeline system. In the creation of subterranean pipe galleries that are comprehensive in some cities, the utilization of waterproof membranes has effectively shielded the power, communication, water supply, and drainage components of the pipe system and enhanced the dependability of urban infrastructure. In projects that are waterproofed by bridges, the importance of elasticity is paramount. It can adjust to the increase and decrease in size of the bridge as a result of temperature changes and vehicle weight. It will provide reliable waterproof protection, and it will prevent rainwater from entering the bridge’s structure, which will lead to the corrosion of steel and the destruction of concrete. In the creation of some large bridges, the utilization of water-resistant membranes that have high elasticity increases the waterproof capacity of the bridge and increases its lifespan. - Businesses and other organizations that specialize in certain industries and have specific goals and objectives.
