PVC Polymer Waterproofing Membrane Production Line

Pvc polymer waterproofing membrane production line is a professional equipment for producing polymer waterproofing coils. The following is its related introduction:

Main equipment and composition

Extruder: It is the core equipment of the production line. It heats and melts the polymer material and then extrude it into shape. Common ones are single-screw extruders and twin-screw extruders, such as the single-screw extruder of Haiming Machinery, with a screw diameter of up to 180mm and a production capacity of 2000kg/h.

Die head: It determines the shape and size of the coil. Its flow channel design is crucial to product quality. It is necessary to ensure that the material is extruded evenly.

Calender: Calender the extruded coil to improve the flatness and glossiness of the coil surface and make the appearance quality of the coil better.

Cooling device: It is used to cool the coil after extrusion so that it can be quickly shaped. There are usually two cooling methods: water cooling and air cooling, which can be selected according to the characteristics of the production equipment and product requirements.

Cutting equipment: Cut the cooled coil according to the set specifications. The accuracy of the cutting equipment directly affects the dimensional accuracy and appearance quality of the product.

Winding device: The cut coils are wound for storage and transportation. Some advanced winding devices have automatic switching functions to improve production efficiency.

Production process

Ingredients: According to the product formula, various polymer raw materials, such as polyethylene, polyvinyl chloride, etc., are accurately weighed and then mixed.

Mixed materials: The weighed raw materials are placed in the mixing equipment and fully stirred at a certain temperature, time and stirring speed to make the components evenly mixed.

Extrusion molding: The mixed materials are fed into the extruder, and under the action of high temperature and screw, the materials are extruded into the initial shape of the coil.

Cooling: The extruded coil immediately enters the cooling device, and its temperature is reduced by water cooling or air cooling to fix the shape.

Cutting: The cooled coil is accurately cut by the cutting equipment according to the required size.

Surface treatment: The cut coil can be coated with a protective layer, sanded or embossed to enhance its waterproof performance and aesthetics.

Quality inspection: Strict quality inspection is carried out on the produced coils, including appearance, thickness, tensile strength, impermeability and other indicators to ensure that the products meet national standards and customer requirements.

Reeling and packaging: The qualified coils are rolled and packaged into finished products for storage or shipment.

Advantages

High production efficiency: The degree of automation is high and continuous production can be achieved, which greatly improves production efficiency and reduces labor costs.

Stable product quality: The use of advanced production equipment and process control can ensure the dimensional accuracy, thickness uniformity and performance stability of the products.

Product diversification: Various types of polymer waterproofing coils can be produced, such as homogeneous coils, internal reinforcement coils, fiber backing coils, etc., to meet the needs of different customers.

Application areas

Widely used in roof waterproofing, basement waterproofing, tunnel waterproofing, reservoir dam waterproofing, grain depot waterproofing, landfill waterproofing and other fields in construction projects.
