Method for identifying wood fiber wallpaper

Four tricks to identify wood fiber wallpaper

Wood fiber wallpaper is the best in environmental protection and breathability, and has the longest service life. It is the best in wallpaper, but how should we identify it when purchasing?

1. smell the smell. Open the sample of the wallpaper, especially the new sample, and smell it. The wood fiber wallpaper emits a light woody scent, which smells almost no smell. If it smells, it is not wood fiber.

2. Burn with fire. This is the most effective way. Wood fiber wallpapers have no black smoke when burned, and the dust after burning is also white; if it is black smoke or smelly, it may be a PVC wallpaper.

3. Do the drip test. This method can detect its gas permeability. Drop a few drops of water on the back of the wallpaper to see if there is water vapor through the paper. If you can't see it, it means that the wallpaper doesn't have breathability, not a wood fiber wallpaper.

4. Use a bubble to soak a small part of the wallpaper into the water, then use your fingers to scratch the surface and back of the wallpaper to see if it fades or soaks. The real wood fiber wallpaper is particularly strong, and the dye is made from flowers and linen. Pure natural ingredients, will not discolor due to blisters.

Rane Rails The standard length of the  the rail are  9, 11, 10, 10.5, 9.5, 9.5, 12, 12.5 m.the contract is agreed By the both party of supplyer and buyer ,also noted that supplyer can supply a percentage of the length of 4 m ~ 8.9 m for random length rail. But when calculating the weight according to the 100 mm into the class. the tolerance  for the  length of rail is + 50 0 mm length. shape  the  lateral bending of rail which is not bigger than 1.5 mm bansed on per meter , the total curvature shall not be bigger r than 8 mm. Upper and lower direction of rail bending may not  bigger than 6mm. the  bending  of rail ends is not bigger than 1 mm  within 0.5 m. Because QU120 Crane Rail straightening equipment capacity constraints. The bending degree of agreement by both parties of supplyer and buyer. The rail torsion is not bigger than 1/10,000 of  total length of rail. Rail cross section and the vertical axis of the asymmetric: rail buttom is not bigger than 2 mm, rail head is not bigger than 0.6 mm.At the bottom of the rail should not be recessed. Base on both sides of the central a protruding is not to be bigger than 0.5mm.
