Problems solved by technology

[0004] The commonly used cooling method is to use water-cooling to shape. The water-cooling method must involve the design of the water-cooling system. The design of the water-cooling system determines the quality of the cooling effect. In the past, the water-cooling system used a unified supply method. Chilled water is led to the cooling process of each production equipment, but with the diversification of product types and the large investment in production equipment, the products and production capacity of different production lines are also different, and the cooling process requirements are also different
[0005] With the addition of production equipment, the water pressure and flow of each production equipment will be unstable, which will directly lead to poor cooling effect and unstable product quality
For the production equipment of different products, due to the difference in the performance of the products produced, the cooling process requirements are also different, and the water temperature required for cooling is also inconsistent. However, the previous unified supply method provided that the chilled water temperature of each production equipment was uniform, and it was impossible. The cooling process of different production equipment is adjusted separately, which further leads to the failure of the excellent performance of the product to be well displayed, and the use value of the produced product will also be reduced accordingly

Abstract

The invention provides a PVC low foaming board water cooling system and a water cooling method thereof. The water cooling system comprises a main water supply circuit and at least one water cooling device, a constant temperature and constant pressure system, comprising at least one water storage tank and a temperature control unit. The temperature control unit comprises a controller, a temperaturemonitoring device and a heating device, and further comprises at least one external circulation loop. The external circulation loop leads first chilled water in a main system and second chilled waterin a storage tank to perform heat exchange. The inner circulation loop comprises the water storage tank, an inner circulation pump, and the water cooling device connected in series through a pipeline, wherein the water cooling device is connected with the water storage tank through the pipeline to ensure that the second chilled water is returned to the water storage tank; and the water cooling method comprises a cooling sizing mold cooling sizing process and a spray cooling process, and applies the second chilled water provided by the water cooling system. The PVC low foaming board water cooling system and the water cooling method thereof provide the second chilled water with constant temperature, constant pressure and constant flow rate for the production of a PVC low foaming board.

Description

technical field [0001] The invention relates to the field of PVC foam board production, in particular to a PVC low-foam board water cooling system and a water cooling method thereof. Background technique [0002] PVC foam board is made of polyvinyl chloride (PVC) as the main raw material. As one of the typical new chemical building materials that replace wood with plastic, it is an ideal green and environmentally friendly building decoration material. It is widely used in vehicle and ship manufacturing, furniture, Kitchen and bathroom materials and decoration industries. [0003] In PVC low-foaming products, high-molecular-weight polymers are added, plasticized by high-temperature heating, extruded, and cooled to shape. The cooling and shaping process is particularly important in the manufacturing process of PVC low-foaming boards. The cooling effect directly affects the low-foaming effect. Foaming quality, crust quality and surface finish of foam board. [0004] The commo...
