Anonymous users2024-01-23First of all, let's take a look at the definition of the two, multi-layer planks.
It is made of three-layer or multi-layer veneer or thin board by high temperature and high pressure of wood board glue, multi-layer plywood.
It is criss-crossed, and the surface is made of solid wood veneer or technical wood. It has the characteristics of small deformation, high strength, good internal quality and good flatness.
The large core board is made of two pieces of veneer intermediate glue splicing board, and the middle board is made of wood board processed into a certain specification of wood strips, which are spliced by a splicing machine. The spliced wooden board is covered with two layers of veneer on both sides, and then glued by a cold and hot press to complete. Large core boards are also called blockboards.
It has the characteristics of dimensional stability, not easy to deform, and high transverse strength.
Multi-layer solid wood panels.
The difference between the large core board and the large core board is mainly explained from the following three points, one: practical performance, the multi-layer wood board is pressed with multi-layer veneer, so the structural stability is very good, not easy to deform, waterproof and stability are very good. Large core board:
The surface of the large core board of good quality is smooth and smooth, not easy to warp and deform, and has the characteristics of high strength and low moisture content, but it is more afraid of moisture and should be avoided in the kitchen and bathroom.
Second: environmental protection, although the environmental protection of multi-layer solid wood board can not be compared with the large core board, but after high temperature and high pressure, PVC edge banding, so that the release of formaldehyde meets the national standard requirements, the large core board has a good and bad score, after the national grade standard, the environmental protection coefficient is relatively strong. When we buy, we must choose E1 grade, not because of the price to choose E2 grade, otherwise formaldehyde emissions will be very high.
Three: price, solid wood multi-layer.
The strength of the plate is mainly related to the plate.
Each additional layer will increase its strength accordingly, but the price will also increase accordingly. Large core board compared to particle board.
It is more expensive, and the transverse bending strength is much higher. The price of the same brand and the same thickness of large core board is also relatively low compared with that of solid wood multilayer board.

Anonymous users2024-01-22Solid wood board is obviously made of complete wood, of course, solid wood is more durable, and the grain is its own texture is very natural. The large core board is made of two veneers spliced together with glue, the vertical bending strength is poor, and it cannot be painted, but the effect of the large core board is good, and the price is relatively cheap.
Solid wood board refers to a large core board made of consistent wood, also known as washing blockboard, which is made of two thin planks sandwiched between some miscellaneous wood strips.

Multi-layer parquet and three-layer parquet are both solid wood parquet, which is made of solid wood veneer or puzzle of different materials with environmentally friendly glue under high temperature hot pressing, among which, three-layer parquet is made of three-layer solid wood veneer staggered lamination. Multi-layer solid wood is made by pressing more than three layers of solid wood boards. >>>More
Plywood is a three-layer or multi-layer plate-like material made of wood segments that are rotary cut into veneer or cut into thin wood by wood planer, and then glued together with adhesive, usually with an odd number of layers of veneer, and the fiber direction of adjacent layers of veneer is glued perpendicular to each other. Compared with ordinary market plywood, multi-layer plywood has small deformation, high strength, good internal quality (small holes and no delamination after sawing), good flatness, and can produce 5-40mm different thicknesses. >>>More
Multi-layer solid wood boards are actually multi-layer boards... It's all about selling furniture and the concept of stealing it, and it's no different from particleboard. >>>More
