The role played by the PVC floor forming chiller in the production line

The production process of PVC flooring involves multiple links such as pressing, cooling and forming, thermoforming, and extrusion, all of which require temperature control. Among them, the cooling link is particularly important, because it determines the quality and output of PVC flooring. The PVC floor forming chiller is mainly used to provide cooling in the PVC floor plastic production line. For example, in the thermoforming process, the cooling of the PVC floor forming chiller can quickly set the PVC floor material and keep its shape without deformation, thereby improving the forming quality of the PVC floor; in the extrusion forming process, by controlling the cooling speed, the stretching and shrinkage of the PVC floor can be adjusted;

The application of PVC floor forming chiller is very important in the production line. Plastic floor production line is an assembly line that completes complex processes, general oil head material and dosage equipment, rock pressing equipment, mixing equipment, molding and surface treatment equipment, dryers, cooling equipment, heating and cooling equipment, grinding equipment, coating equipment , main and winding equipment. Among them, the equipment for controlling the temperature of the equipment mainly includes heating equipment and cooling equipment, which are mainly concentrated in cooling machine materials, heating molding machines, and drying links to provide suitable temperatures for this link. Floor production temperature control is extremely important in the production of plastic flooring, and even determines the quality of plastic flooring.

PVC floor forming chiller equipment is a machine that provides cooling. On the one hand, it provides cooling for the thermoforming machine, keeping the temperature of the cooling roll at 8-12°C, and quickly shaping the floor material without deformation. On the other hand, the chiller equipment is used to control the rapid cooling of the plastic floor machine after the embossing roller is formed, so that the embossing pattern can be easily bonded with the ground glue, and the quality and output of the plastic floor can be improved.

Jiusheng PVC floor molding chillers are divided into water-cooled chillers and air-cooled chillers according to their condensation methods. Different choices can be made according to installation space and cost considerations. The selection of chillers is related to the actual cooling capacity. Parameters such as cold water outlet temperature and flow, cooling water inlet temperature, flow, and fouling coefficient are important selection factors.

What should be paid attention to when choosing a chiller?

1. The outlet temperature of cold water should not exceed 15°C;

2. The outer dry bulb temperature of the air-cooled unit should not exceed 43°C. If it exceeds, check whether the operating range of the compressor is exceeded, whether the power of the equipped resistance motor is sufficient, and configure components reasonably.

During the installation of Jiusheng water-cooled chiller, the following three points should be paid attention to in the selection and installation:

1. It is best to choose a good quality configuration.

When determining the power: select configurations such as compressors, electrical appliances, and water pumps from major international brands. For air-cooled condensers, choose copper-sleeved aluminum fins instead of micro-channel aluminum fins. The heat dissipation effect is poor. Copper evaporators The tube material has better thermal conductivity. Do not choose stainless steel, which is cheap in cost and poor in heat exchange. The water-cooled type takes into account the problem of environmental water sources. The water-cooled type needs to be connected to a cooling water tower. If conditions permit, the water-cooled type can be selected.

2. After the pipeline installation and test pass, the pipeline should be painted and heat-insulated.

3.It is necessary to mark the pipes and valves, and hang the chilled water use process system diagram near the chiller. The installation and selection of the valves of the water-cooled chiller unit used in the plastic floor production line is critical, otherwise leakage will occur during use. Bring losses to the production of plastic flooring.

Therefore, production enterprises should comprehensively consider the above factors and choose PVC floor forming chillers with high quality, environmental protection, reliability, high efficiency and reasonable price to improve production efficiency and reduce production costs.
