WPC WPC talk additives commonly used in production

 

WPC wood flooring in equipment selection of various additives, crosslinking agents, lubricants, colorants, chemical foaming agents and fungicides greatest impact on the quality of WPC. For WPC special additives, different matrix resin additives need to be developed to meet specific performance composite products or processing performance requirements, therefore, WPC additives variety, choosing the right additives for WPC wood plastic composite flooring Equipment the production is essential. WPC conventional additives in the composite material in its role as follows:

Colorants

WPC colorants require relatively high, to have a high degree of color intensity and brilliant; good transparency or hiding, dispersion, weather resistance, thermal stability, chemical stability, electrical function, environmental performance, because Tonga people want to add these organic pigments to hide the original color of wood. These coloring agents not only make products have uniform and stable color, it can improve the light properties of the product, so that the color of the product remains unchanged for a long time.What is the best composite/plastic decking materials

Coupling

Also known as the surface modifying agent, is a way to make the surface between the plastic and wood have a very strong interfacial bonding, to improve their compatibility and dispersibility of an additive. WPC wood floor coupling during processing equipment can also reduce the melt viscosity synthetic resin, but also can reduce the flour water absorption, improve processing performance, so that products have a good appearance and improve the mechanical properties. Coupling agent silane coupling agent, isocyanates, cumene hydroperoxide, aluminum esters, phthalic acid esters and the like.

Ultraviolet light stabilizers
Can make a polymer composite mechanical performance. Such as adding a hindered amine light stabilizer directly on wood fiber filled PE products, can be very effective in preventing aging. Light stabilizers commonly used are: hindered amine light stabilizer and an ultraviolet absorber.

Vesicant

You can reduce the material density and product weight, mainly exothermic (AZO carbon amine), endothermic (sodium bicarbonate)

Lubricants

In the processing of WPC composite wood flooring equipment by adding lubricant to reduce friction compound and processing machinery, the processing equipment to play the best operating characteristics, and can improve liquidity and increase the melt extrusion appearance of product quality and increase production. Commonly used lubricants are: hard bile, zinc ethylene bis-fatty acid amide, polyester wax, stearic acid, lead stearate, polyethylene wax, paraffin wax, oxidized polyethylene wax.
WPC wood floor equipment in the correct choice of additives to improve both the inherent properties of WPC is to improve the processing performance is a critical factor. Warp, crack, stain problems sometimes occur on the surface of the material, then you need the help of additives. In WPC WPC decking composite extrusion line equipment, to get the right speed and smooth out the surface in order to avoid the so-called edge cracking additives also need to have a go.
