I. Why is a water /air cooled screw chiller important in the production of PVC plastic flooring?
1.Printing and coating links
in the process of printing and coating the floor film, you need to use the air cooled screw chiller to quickly cool the floor film that has been printed or coated to solidify the printing and coating layer, and to ensure that its surface quality and flatness. Failure to use a air cooled screw chiller for cooling during the printing and coating process may result in the following effects:1.1Inadequate curing
After printing and coating, the ink or coating on the surface of the flooring membrane needs to be cured quickly to ensure its adhesion and durability. If not cooled down in time, the surface temperature of the flooring membrane may be too high, resulting in slow curing, which affects your productivity and may lead to incomplete curing of the printed or coated layer, resulting in problems with the quality of your product.
1.2Coating Deformation and Flow
Coatings on the surface of your flooring film may flow and deform at high temperatures, especially coated coatings or adhesives. Failure to reduce the temperature in time will increase the risk of coating flow, resulting in uneven coating or traces of coating flow, affecting the appearance and quality of your PVC plastic flooring membrane.
1.3Poor surface quality
The surface of the flooring membrane at high temperatures is prone to bubbles, depressions, or defects, affecting the surface quality and gloss of the flooring product. Timely cooling can effectively reduce the occurrence of these defects, to ensure the smoothness and quality of the surface of PVC plastic flooring.
1.4Increased processing difficulty
If the surface temperature of the floor film is too high, it may increase the difficulty of subsequent processing, such as cutting, calendaring, and other links. This may lead to extrusion or deformation during processing, affecting the consistency of product size and shape.
2.Calendering
In the process of calendering the flooring film through the calendar, you can use a air cooled screw chiller to cool down the cooling rollers, keep the temperature of the cooling rollers between 8~12℃ to cool down the flooring film to ensure the shape and thickness of the flooring film can be stabilized and to avoid deformation or shrinkage of the film. In the calendering process, if the air cooled screw type chiller is not used to reduce the temperature, it may cause the following adverse effects:2.1Product Deformation and Shrinkage
During the calendering process, PVC flooring film is processed at high temperatures and high pressures, and if it is not cooled promptly, the surface temperature of the flooring film may become too high, causing the flooring film to deform or shrink. This may lead to an unstable size or irregular shape of the flooring product, affecting the appearance and performance of the product.
2.2Insufficient hardness of the floor film material
The floor film needs to be cooled quickly after calendering to ensure its surface hardness and strength. If it is not cooled in time, the floor film material may be in a high-temperature state, resulting in insufficient hardness, which is easy to be affected by external impact or pressure, affecting the durability and service life of the product.
2.3Surface Quality Problems
High surface temperatures of the flooring membrane may cause the coating or texture to flow or deform during the calendering process, affecting the surface quality and decorative effect of the flooring product. This may lead to uneven, defective, or bumpy surfaces of the flooring products, affecting the aesthetics and market competitiveness of the products.
2.4Decrease in production efficiency
Failure to cool the flooring film in time will prolong the production cycle and reduce production efficiency. Floor film needs extra time to cool naturally, which may lead to increased production line downtime, decreased productivity, and increased production costs.
2.5Increased wear and tear on equipment
High-temperature floor film may accelerate wear and tear on equipment, especially components such as calendar rollers that come into contact with the film. Prolonged use of high-temperature floor film may lead to increased wear and tear of equipment components, affecting the service life and stability of the equipment.
3.Cooling and curing link
Finally, after the flooring membrane has been calendered and molded, it needs to be rapidly cooled by a air cooled screw type chiller to speed up the curing of the flooring product, which facilitates allowing the nibbling pattern to adhere to the ground glue and ensures its surface hardness and flatness. At the same time, timely cooling means that the time taken to cure and cool the flooring membrane is shortened, reducing energy consumption and production costs.II. How to choose a water/air cooled screw chiller?
The air cooled screw water chiller market is flooded with various brands and models, which is often confusing for customers. Some sellers may exaggerate product performance and features to attract customers with false advertising. This situation makes it difficult for customers to identify a truly suitable and reliable air cooled screw water chiller. To ensure that you buy a good quality product, you should consider the following key factors before making a decision:
Raw materials of the air cooled screw water chiller: different parts and accessories will have an impact on the quality of the product, take the compressor as an example, a high-quality compressor usually has higher energy efficiency, more stable operation, and lower noise level, which can provide more reliable and efficient refrigeration effect. Kassel KSW series of packaged air cooled chiller adopts the American Copeland compressor, which is stable in performance and has a low failure rate; it adopts the Schneider electrical The control system adopts Schneider Electric, which can realize precise temperature control and real-time display of system operation faults.
After-sales service of the packaged air cooled chiller: you need to examine whether your supplier has the ability and willingness to provide you with technical support, including fault repair, but also operational training, technical support, spare parts supply, and other aspects of technical support, to reduce the risk you face in the process of using the packaged air cooled chiller. Kassel, as a professional air cooled water chiller suppliers , has always been committed to providing our customers with quality products and perfect after-sales service. Whether in terms of product quality or after-sales service, Kassel always puts customers' needs in the first place to ensure that customers can get the best use experience and service experience.
Company strength: the strength of the supplier is also one of the key factors you need to consider when purchasing, strong companies usually have advanced production equipment and mature product production technology, able to provide high-quality products and services, to ensure that the quality of your products is guaranteed, to avoid the risks and losses brought about by the supplier's quality problems.
