The production process of synthetic resin tile

At present, the production process of domestic synthetic resin tiles is very mature, stable and skilled production technical support and strict product quality control, excellent performance makes synthetic resin tiles more and more popular in the market. Next, let's take a look at the production process of synthetic resin tiles:

The first step, mixing: Pour the raw materials (PVC resin, light calcium carbonate, weather-resistant engineering plastic ASA co-extrusion, etc.) into the conical hopper of the mixer according to a certain proportion, and the raw materials are extracted by the fan and transported to the mixing by the screw rod Machine-enclosed material bucket, after mixing, the material is discharged into the stainless steel material box through the discharge port of the mixer, and the material box is covered with a regular round hole dug in the middle of the cover. The discharge port and the round hole of the material box cover are connected by pipes to form a closed discharge space.

The second step, feeding: the material box is transferred to the feeder of the extruder, and the mixed raw materials are manually shoveled to the conical hopper of the feeder. The raw material is conveyed to the extruder conical hopper through the screw rod. The discharge port of the screw rod and the feed port of the extruder are connected with a plastic bag to form a closed discharge space.

The third step, extrusion: the raw material enters the extruder chamber, and is heated to about 200 ℃ by electricity, and the raw material is in a molten state. The molten resin in the equipment enters the closed cavity of the mold, and after the cavity is filled, the plastic is extruded to form a sheet of resin (ie, the bottom layer of the synthetic resin tile). In order to make the finished product have the functions of fire prevention and anti-aging, the surface of the sheet resin is covered with a layer of ASA coating. Pour the ASA material into the conical hopper of the extruder supporting equipment, and directly cover the entire feeding port with a plastic bag when feeding. The equipment is heated at 175°C, and the ASA is melted and directly coated on the surface of the sheet resin to form a uniform coating.

The fourth step, molding: the sheet resin is embossed by double rollers and then enters the molding machine to form a specification tile. The molding machine is indirectly cooled by fans and circulating water.

The fifth step, cutting: under the driving action of the forming machine, the semi-finished tiles are cut into tiles of a predetermined length.

The sixth step, inspection: the cut products enter the inspection process, and the unqualified products are inspected.
