Q:What is the difference between laminated lumber (LVL) and plywood (plywood)?

LVL is also called "forward" plywood. Generally, the wood fibers of each floor are in the opposite direction. In this case, the consequent forces are relatively large. For structural problems, there are a few layers that will be horizontal, such as the two floor.

Q:What are the differences between bamboo plywood and wooden formwork, which is more suitable for tall buildings?

The difference between bamboo and wood template: Bamboo due to the limitations of material properties, thickness tolerance is not easy to grasp, wood formwork construction is easy to nail, sawing, drilling, light weight in bamboo, each has its advantages and disadvantages. Overall, the performance is higher than that of bamboo plywood, bamboo plywood is widely used, in addition to the construction engineering, and is especially suitable for railway, highway, river sea bridge, such as cast-in-place beam, continuous beam, tunnel, viaduct, dam, subway and car floor, brick pallet container, etc.. For high-quality engineering, it is still more suitable for choosing bamboo plywood.

Q:What is an offset press? And what are the machines for printing paper?

Press the input in different ways, can be divided into the sheetfed and web offset printing machine; according to the chromatic number of a complete paper can be divided into single color, double color, four-color and multicolor printing machine; according to the maximum printing paper format can be divided into small press, six open, four open, a piece of paper and printing machine, in addition to a paper double-sided printing machine can be completed at the same time printed on both sides of the. According to the distribution system can be divided into alcohol machine (ie alcohol dampening offset press, water wheel (that is wet plate offset press) and waterless offset press.

Q:What is bamboo plywood?

Bamboo plywood is made of bamboo material as the main structure and filling material! The main uses are: building mould, grouting, car box, box and box bottom board, large mechanical outer packing board, and various places where the board is needed! 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 can cut the row, can replace wood, therefore, the State Forestry Department policy supports the development of wood-based panels with bamboo as the main materials, has replaced the use of wood plates in a lot of places!

Q:Pressing process of plywood

Plywood is one of the commonly used furniture materials. It is a kind of artificial board. A set of veneers usually glued together in a direction perpendicular to the direction of the adjacent layers of wood. Usually the table plate and the inner plate are symmetrically arranged on both sides of the central layer or the core of the plate. A single slab made of glued sheets that are Criss crossed in the direction of wood grain. The number of layers is generally odd, and even a few are even. The physical and mechanical properties of the vertical and horizontal directions are less different. There are three commonly used plywood, plywood etc.. Plywood can improve wood utilization, and it is a main way to save wood. They can also be used in aircraft, ships, trains, automobiles, buildings and packing boxes.
