Q:What are the differences between LVL, LVB, plywood and plywood? Is it divided by the use of it, or is it just a different name?!

Name is not the same, the structure of the plate is not the same, the pressure and the degree of seed is not the same.

Q:Can the bamboo plywood used for building be made at home?

Because of the high hardness, bending resistance and compressive resistance of bamboo plywood, steel formwork has been replaced in many use areas! Because bamboo is easy to cultivate, quick forest trees, three to five years will be cut down, can replace wood to make furniture, but to choose good quality. I hope my answer is useful to you.

Q:Which is the thickness of plywood and plywood?

The first is correct, how thick is too thick, and the thickness below is positive and negative, not standard,For example, the correct one is "3MM", and the following is "2.7MM". The top is the standard thickness, and the following is the flux thickness,

Q:How much is it per square metre to be decorated with plywood?

The principle of symmetry principle: single center plane plate on both sides of the water, both species veneer thickness, layer, manufacturing method, fiber direction and single board rate should correspond with each other, which is symmetrical on both sides of the center plane of each layer corresponding to the principle of plywood in different direction stress phase etc.. Therefore, when the change of veneer moisture content, its stable structure, no deformation, cracking and other defects; on the contrary, if the symmetry center plane of corresponding layer there are some differences, will make the center plane on both sides of single board stress is not equal, the deformation and cracking of plywood. Principle of odd number layer: because the structure of plywood is adjacent layer, the fiber direction of single board is perpendicular to each other, and must accord with symmetry principle, so its total number of layers must be odd number. Such as: three laminates, five laminates, seven laminates and so on. When the odd ply plywood is bent, the maximum horizontal shear stress acts on the central veneer to make it have greater strength. Even when the plywood is bent, the maximum horizontal shear stress acts on the adhesive layer, not on the veneer. It can destroy the adhesive layer and reduce the strength of plywood.

Q:What is plywood?

It is commonly known as plywood plywood, natural wood boiled softening, use of wood along the ring spin into large slices (veneer) in general 2.7mm thickness 20mm and above, according to the principle of symmetry, generally consists of three or more layers of a millimeter thick thin veneer, wood fiber layer adjacent to each other in the vertical blank, after drying, imposition, glue, hot pressing, glued into three or more layers (usually 3 - odd layer, 13 layer plate material). High quality product surface is smooth and smooth, without degumming, sand injury, press injury, no obvious color difference, no stains, good size processing accuracy, small thickness deviation, bonding strength 0.7Mpa, moisture content 6 - 14%. Usually used as substrates and panels, they can be used in building, interior decoration, furniture manufacturing, shipbuilding, packaging and other industrial products.Buy Plywood first, look at environmental protection. Depends on whether the release of harmful gases in line with national standards, especially the release of formaldehyde free glue is excessive. For these professional too strong things, most consumers may not clear, and can not be measured, so it is a shortcut to see whether manufacturers have environmental labeling products in china. Because to pass the certification, must be based on quality, environmental protection double standards as the premise.Next, look at the material. The price of different tree species is different. Consumers can choose different kinds of materials according to different demands. At present, the market is full of a large number of low price of Eucalyptus core plywood. In fact, this is the poplar core board made of surface coloring treatment, so the appearance of the board is basically the same, but the quality is very different. In fact, the core board, whether it is component or hardness, toughness, are higher than poplar core board, consumers should carefully identify when buying, so as not to be fooled.

Q:Plywood surface bonding strength is very important, as a leading brand of plywood in China, how about this aspect?

The plywood surface bonding strength more than 0.4MPa provisions of the state. The bond strength refers to the special adhesive for special steel clip (steel head bottom surface area of 400 mm2 2*2 cm) bottom surface adhesion in the specimen along the central, around the cut card head decoration layer board, cutting depth to the substrate surface, and then completely after the cement (1 hours later), then pull straight up, pull Newton said.

Q:Will the steel formwork be replaced by bamboo plywood in future construction?

The selection of formwork materials once had twists and turns. Until the 70s of last century, the main building blocks were wood, including formwork and wood plywood;

Q:Do you need a composite board or a splint for the new wardrobe?

General customers do not require special, businesses will use low density board or particleboard. Special requirements of customers, will also use plywood or finger board, solid wood. Solid wood or finger board is the most expensive, solid wood may be wet with temperature, dry, will burst or not open the door. Plywood prices are second, and others are cheaper.

Q:What kind of glue does plywood use now?

Depending on the composition of the gum, the glue used for building plywood is as follows:Urea formaldehyde adhesive: moisture-proof glue / for interior decoration, furniture, not for outdoor use.Melamine glue: moisture resistant, and has a certain water resistance and climate resistance / can be used outdoors or indoors, but not often immersed in water.Phenolic glue: moisture proof, excellent water boiling resistance and climate resistance characteristics can be used for outdoor or indoor / outdoor, can withstand exposed to wind and rain.

Q:What is the production process of bamboo plywood?

The four roller coating machine soluble phenolic resin on bamboo roller coating glue water, the quantity is 300, 350g/ square meters (double). Adhesive can be added 1%--3% flour, soy flour and other fillers. The filling agent causes the bamboo sheet to form a gum film on the surface after gluing, which is difficult to produce flowing glue when hot pressing, and the brittleness of the adhesive layer can be improved after curing.
