Artificial stone countertops how to judge good or bad?
Check whether the product ISO quality system certification, environmental certification mark, quality inspection report, with or without product warranty card and related security signs.
A look: visual samples of pure color is not cloudy, good permeability, the surface is not similar to the plastic plastic texture, the surface of the plate without small pores;
Two touch: hand touch the surface of the sample has a sense of silk, no astringent sense, no obvious sense of uneven. (Which can be identified using aluminum hydroxide, or the use of calcium carbonate);
Three strokes: with the nail plate surface, no obvious scratches;
Four test: soy sauce can be used to test the permeability of the table (the result is no penetration); the use of edible vinegar test whether the addition of calcium carbonate (the results are not discoloration and no powder); using lighter burn table samples (the result is flame retardant, , The higher the acrylic content of the table no taste);
Because the artificial stone pattern, color and more easy to shape, which makes it the most common use of the overall cabinet countertop material, but some of the poor quality of artificial stone countertops often appear cracks, artificial stone quality depends mainly on the quality of material Add aluminum powder or calcium powder. Aluminum chemical composition is aluminum hydroxide, the stability is better, but also more environmentally friendly; and calcium chemical composition of calcium carbonate, relatively rough, anti-permeability, stability is relatively poor. The price of calcium powder is about one tenth of the price of aluminum powder.
With the naked eye consumers simply can not be presented separately material. In general, consumers can judge by two ways: (1) saw the observation. Good quality man-made stone cross-section from the volume, showing flake. And poor quality is broken, the adhesion is relatively poor. (2) Ignition observation. Take a 50 cm small sample, ignited the alcohol lamp blue flame, and then slowly leave the flame, aluminum plate flame will be automatically extinguished in 3 seconds, and calcium powder board flame will last more than 10 seconds.
