SUN HONG
The vacuum suction box cover is mainly located in the dehydration area of the net. It is the first component under the breast roll net of the paper machine. Its function is to help the water on the pulp on the forming fabric to be quickly discharged through the vacuum effect, thereby accelerating the paper forming process. The vacuum suction box cover is in direct contact with the forming fabric and absorbs water through the openings or notches on its surface to ensure the rapid forming and uniform dehydration of the pulp.
(1) Help the pulp to dewatering quickly: When the pulp passes through the forming fabric, the water in the pulp is quickly extracted through the vacuum effect, reducing the retention of water on the forming fabric and improving the dewatering efficiency.
(2) Stabilize the paper: During the dewatering process, the vacuum box can better shape the fibers and reduce the movement of the fibers on the forming fabric, so that the structure of the paper will be more uniform and stable.
(3) Improve the strength and quality of the paper: Dewatering can help improve the dryness, strength, uniformity and surface finish of the paper, which is very important for high strength packaging paper, cultural paper and other paper types.
Sun Hong can provide you with vacuum suction box cover made of polymer and ceramic materials. HDPE and UHMWPE are common panel materials with excellent wear resistance, corrosion resistance and low friction. Ceramic vacuum suction box cover is usually used in high speed paper machines or high wear environments. They have strong wear resistance and stability, long service life, and are suitable for long term stable operation.
Surface design:
The holes and grooves can be customized according to customer needs. Sun Hong has a variety of designs to choose from.
(1) High wear resistance and service life.
(2) Easy maintenance and replacement. The modular structure of the vacuum box panel is easy to disassemble and replace, shortening the downtime of the paper machine.
(3) Reduce wear on the forming fabric.
