Abstract
A process of polyvinyl chloride (PVC) cladding wood includes step 1, putting a PVC mixture into a high-speed mixer, and then cooling through a rubber powder cooler to obtain a powder; step 2, adding the powder to a granulator for granulation to produce PVC particles with uniform particle size; step 3, heating a profile to be cladded at an average speed in an extruder, melting with the PVC particles, and extruding out by a co-extrusion die to form a profile with PVC material coating on a surface of the profile; step 4, after cooling by a cooling tank, forming and tracting, cutting; the process of PVC cladding wood is completed. The process of PVC cladding wood involved in the present invention attaches the PVC coating to the outer surface of a pure wood or a wood-like profile.
Claims7
A process of cladding wood with polyvinyl chloride (PVC), comprising the following steps:
- step 1, putting a PVC mixture into a high-speed mixer, and then cooling the PVC mixture to a temperature of 60° C. through a rubber powder cooler to obtain a powder;
- step 2, adding the powder to a granulator for a granulation to produce PVC particles with uniform particle size;
- step 3, heating a wood profile to be cladded in an extruder, adding the PVC particles to the extruder to form a melted PVC material, and extruding out the melted PVC material by a co-extrusion die to form a PVC material coating on the wood profile;
- and
- step 4, cooling the profile with the PVC material coating by a cooling tank to obtain a first resulting profile, conducting a forming and traction on the first resulting profile to obtain a second resulting profile, and cutting the second resulting profile.
