Advantages and Disadvantages of PVC-Wood Products - Guangyuan Ruifeng New Materials

Advantages and Disadvantages of PVC-Wood Products - Guangyuan Ruifeng New Materials

It is Wood-Plastic Composites (WPC), a new type of composite material that has emerged worldwide in recent years. It uses polyethylene (PE), polypropylene (PP), and polyvinyl chloride (PVC), etc., to replace conventional resin adhesives, and mixes them with more than 35%-70% of wood flour, rice husk, straw and other waste plant fibers to form a new wood material. Through extrusion, molding, injection molding and other plastic processing technologies, it produces boards or profiles.

Causes and Solutions of PVC Injection Molding Defects (Part 3) - Guangyuan Ruifeng New Materials

Causes and Solutions of PVC Injection Molding Defects (Part 3) - Guangyuan Ruifeng New Materials

(1) Injection pressure is too high, it should be lowered appropriately. (2) Holding pressure time is too long, it should be shortened appropriately. (3) Mold temperature is too low, it should be increased appropriately. (4) Ejection device setting is unreasonable, the ejection cross-sectional area and ejection points should be increased as much as possible. (5) Demolding slope is insufficient, it should be increased appropriately. (6) Melt temperature is too low, the barrel temperature should be increased appropriately.

Causes and Solutions of PVC Injection Molding Product Forming Failures (Part 1) - Guangyuan Ruifeng New Materials

Causes and Solutions of PVC Injection Molding Product Forming Failures (Part 1) - Guangyuan Ruifeng New Materials

The mold temperature is too low and should be increased appropriately. In particular, the mold cooling circuit should be reasonably set to maintain a uniform mold temperature. The wall of the product is too thin, and the melt filling resistance is too large. The shape and structure of the product should be reasonably adjusted where possible.

Discoloration of PVC environmentally friendly products - Guangyuan Ruifeng New Materials

Discoloration of PVC environmentally friendly products - Guangyuan Ruifeng New Materials

Non-uniform color was found during processing (minor color deviation is acceptable); the profile showed significant yellowing after heat deformation; the state was good after heating, but the profile turned gray shortly after being made into doors and windows. The profile did not yellow during normal production, but yellowed later when made into window products.

PVC eco-friendly products aging resistance series issues——Guangyuan Ruifeng New Materials

PVC eco-friendly products aging resistance series issues——Guangyuan Ruifeng New Materials

We all know that the aging process of materials is very complex and is affected by many factors. For a material to be durable and resistant to aging, in addition to the base material itself being strong (having a good foundation), the added pigments, auxiliaries, etc., must be carefully selected. Otherwise, using unsuitable ones will accelerate the aging of the material.
