Production process of Hangzhou POLYTECH plastic glazed tile

- Mar 31, 2020-

Hangzhou Polytech Plastic Machinery Co., Ltd. is the largest manufacturer of resin tile equipment in China. It is committed to producing professional plastic glazed tile equipment for 2 years. Resin tiles, also known as plastic glazed tiles and antique tiles, are used by more and more roofs. The rich color of plastic glazed tiles is a gorgeous landscape on the roof.At present, the production process of the plastic glazed tile equipment of Hangzhou baolitai Plastic Machinery Co., Ltd. has been very mature, with stable and skilled production technology support and strict product quality control, and excellent performance, the plastic glazed tile equipment is more and more popular in the market. And occupy almost all the market share of the country.Next, Hangzhou Polytech Plastic Machinery Co., Ltd. sorted out the production process of plastic glazed tile and shared it with you:

Brief introduction of production process of plastic glazed tile:

The first step, mixing: pour the raw materials (PVC resin, light calcium carbonate, PE wax and other raw materials) into the conical hopper of the mixer according to a certain proportion. The raw materials are extracted by the fan and transported to the closed bucket of the mixer through the screw rod. After mixing, the raw materials are discharged to the stainless steel bin through the discharge port of the mixer. The bin is covered and a regular round hole is dug in the middle of the cover. The discharge port and the round hole of the bin cover are connected by pipes to form a closed discharge space.

The second step, feeding: transfer the material box to the extruder feeding machine, and manually shovel the mixed material to the conical hopper of the extruder. The raw material is conveyed to the conical hopper of the extruder through the screw rod. The screw rod outlet and the extruder inlet are connected with plastic bags to form a closed discharge space.

The third step, extrusion: the raw material enters the extruder chamber, and is electrically heated to about 200 ℃, and the raw material is in a molten state. The molten resin in the equipment enters the closed die cavity of the die, and the plastic is extruded to form sheet resin (i.e. the bottom layer of plastic glazed tile) after filling the die cavity. In order to make the finished products have the function of fireproofing and aging resistance, the surface of the flake resin is covered with a layer of ASA coating. The ASA material is poured into the conical hopper of the matching equipment of the extruder, and the plastic bag is directly covered at the whole feeding port when feeding. When the equipment is heated to 175 ℃, ASA will directly cover the flake resin surface after melting to form a uniform coating.

The fourth step is molding: the sheet resin enters the molding machine after being embossed by double rollers to form the specification tile shape. The molding machine adopts fan indirect cooling.

The fifth step, cutting: under the drive of the molding machine, the semi-finished tiles are cut into tiles of predetermined length.

Step 6, inspection: the cut products enter the inspection process, the unqualified products are recycled, and the qualified products enter the finished products for sale area.

Hangzhou Polytech Plastic Machinery Co., Ltd. uses two or three layers and the latest four layers coextrusion technology to finish processing at a time. Each layer of material has its own function. The surface material is super weather resistant resin to ensure the durability and chemical corrosion resistance of the product; the middle layer material is recycled PVC plastic products to reduce production costs; the bottom layer material is white ductile material to reduce production costs Increase the sense of space and brightness of the workshop. Different materials endow the products with their own functional characteristics. The surface is smooth and organically combined, which makes the new generation of APVC anti-corrosion composite wave plate solve the problems of product durability, corrosion resistance, small rigidity, sense of space and beauty.
