artificial stone formula
The design of the formula involves the ratio of resin, curing agent, accelerator, the weight ratio of resin to filler (glue ratio), the ratio between the thickness of the filler and the proportion of the dye and the temperature. A complete artificial stone formula is composed of resin, curing agent, accelerator, dye, filler, filler and by the different size, color, the laminated wood plastic board Portugal number of particles, (particles are also polyester resin filler, dyes made of sheet metal, Made by crushing and sieving). The ratio of resin to filler is called glue ratio, (weight ratio) Reasonable glue ratio (ie, consistency) has easy to facilitate the formation of easy, the product is not deformed, high density, no bubbles, if the material in the resin content is high, Product shrinkage deformation, high cost.
If the material in the resin content is low, thick material is difficult to discharge bubbles, forming difficult to become waste products. The formula to have a reasonable packing gradation, the formula that there are coarse particles, and fine particles in the formation of different color structure, while the filler in eco wood plastic roofing for patio North America the largest density, but also the formation of different color structure, its surface area And the smallest, that is, the smooth discharge of the bubble also prevents the product deformation, if the filler material in the high side
its total surface area is too small, the amount of resin is too small, which is not easy to exclude bubbles, the opposite filler fine material, its surface area Increase the amount of resin it needs to be wrapped, the product shrinkage increases, the greater the deformation, the reasonable level of the lower cost, a formula exterior synthetic lumber products France that is to have a reasonable packing gradation and have a reasonable Glue ratio, so each color should have an independent formula, and some manufacturers no matter what color is only a resin 40% and 60% of the proportion of filler, is extremely scientific and reasonable, and the use of dye is also Key, in addition to the choice of product use, some dyes in the formula only a few thousandths, several hundred thousandths or even a few million parts of the amount, so you must first use the resin by a few times or even hundred Times the dilution, in order to accurately furnish, otherwise portable composite outdoor wood decking
it will cause color, which is the key to the formula.
