The real pineapple lattice is dark and dark red, and the cross section of the pineapple lattice is yellow or brown, while the fake pineapple lattice is not so dark. In addition, the cross section is darker than the panel, and it can be seen that it is made of a whole piece of wood. Control contains rich black gum and sulfur-colored deposits, which are obvious to the naked eye and soluble in water to turn water yellow. In addition, longan (commonly known as small pineapple lattice) is generally used as pineapple lattice (pineapple lattice wood) in the market. You should know that the real pineapple lattice contains gold thread, and there are minerals in the pineapple lattice wood because of the growing environment, so the stability of the pineapple lattice wood is very good. Although the fake pineapple lattice may be similar in color, there is absolutely no gold thread in it.
Secondly, look at the surface:
The surface of the pineapple lattice should be smooth, free from burrs and cutting tool marks, and free from glue penetration and surface pollution (such as local blackening and yellowing). Try to select the surface of the plate without cracks, cracks, knots, skins, resin capsules and rubber channels, and the natural warpage of the whole plate should be as small as possible to avoid sand penetration revealed by the substrate due to improper sanding process operation. There are many obvious pits in the skin. Look at the location of the scarred side, and then look for the corresponding pattern on the other side. There are ripple marks on the rotary surface and material surface.
Furthermore, we have to look at its texture:
Look at the texture of the pineapple grid plate. This method is suitable for the unpainted pineapple grid. The texture of the pineapple grid generally presents golden minerals, and its weight is ok and relatively light. In addition, it is not high density that can be called good wood. The density of pineapple lattice is not high, but its quality is good and stable, and the density is not directly proportional to the quality. The real pineapple pattern is beautiful, beautiful and clear, and the texture is staggered back and forth, but the staggered pattern is orderly, not chaotic. The pattern of fake pineapple lattice is not beautiful, there is no aesthetic feeling, and the texture is out of order. If you encounter a fake, you can't clearly distinguish the texture of pineapple lattice solid wood.
Finally, we should smell the smell when shopping:
Choose a pineapple lattice with low formaldehyde emission, and don't choose one with pungent taste. Because the bigger the smell, the higher the formaldehyde emission, the more serious the pollution and the greater the harm. The real pineapple solid wood has a faint fragrance, while the fake one has a pungent smell, so this method is easy to distinguish.
There must be a base for a truly qualified commodity price. Take the pineapple grid as an example. The price of high-quality Indonesian pineapple grid 10000/ cubic meter is above, but the price of some manufacturers has dropped a lot. Some illegal pineapple manufacturers will make their products substandard, which will disrupt the pineapple preservative wood market, so consumers should not only pursue cheapness, but also consider quality. However, it is not necessarily that the quality of things purchased by big shopping malls is good, but it is indeed more secure, and after-sales service will be more professional when product quality problems are found. However, large shopping malls often take advantage of consumers' blind trust to make shoddy goods and paralyze consumers. Generally speaking, if the dealers provide more and more complete proof of pineapple information, their products will be more secure. But consumers should be wary of the other party providing some meaningless and valuable documents. Generally, the proof documents that should be provided for the pineapple-lattice preservative wood are the production license for anticorrosion and pressure treatment (because preservatives need to be used under special protection conditions), the environmental protection certificate (ISO 1400 1), the product quality certification system certificate (ISO900 1) and the commodity inspection certificate (imported products).
