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

Plywood PLYWOOD, usually refers to the adjacent layer of wood fiber in the way of crossing, in order to tension is even.

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:Please master, simple and easy to tell me what is: plywood, composite board, the kind of wood powder pressed into what the board? What are their characteristics, please?

Plywood is a layer of wood veneer piled up, because it is horizontal and vertical superimposed, good physical performance

Q:What kind of glue does bamboo plywood use in general?

Water soluble phenolic resin adhesive is usually used. Water soluble phenolic resin adhesive is one of the most important types of insoluble phenolic resin adhesive. The component of free phenol content is low (usually <2.5%), less harm to human body, and a water soluble phenolic resin can save a large amount of organic solvent, easy cleaning in coating operation, so it is widely used in wood processing industry. The binder is mainly used for bonding wood.Bamboo plywood is made of bamboo with groove and equal thickness bamboo as its unit, and bamboo is made by rolling and planing. Bamboo plywood can be used as an ordinary structural board, and also can be used as the floor of a car by the length and surface treatment of sheet metal

Q:Ceiling, how one stone slab

Grasp the main line thick, auxiliary line fine principle. 2 make sure you don't mark the wrong height

Q:What are the common quality defects of plywood?

Bubble and local plastic is the reason for dropping too fast, less adhesive pressure time, veneer moisture content is too high, when the glue point blank or single plate is caused by inclusion, dirt, or the use of pine veneer high temperature causes.

Q:Is solid wood composite floor plywood made of plywood?

Do not pay attention to the plywood core material, an anti two piece surface quality is good, "sell" can be a good. And solid wood composite floor, the size of each board are in

Q:Will the ceiling be made of plywood or plasterboard?

Plasterboard is good, plywood is easy to change, gesso board cannot make big modelling, big modelling uses medium density board

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?

Pre pressure in order to prevent slab displacement is generated to heat press plate when caused by laminated core, seam defects before the blank after hot pressing, to slab preloading at room temperature, the material is glued into a whole.The hot pressing using heat bonding technology, the hot pressing temperature is about 140oC, the unit pressure is 2.5 3.0MPa, hot pressing time is calculated according to the sheet thickness, usually 1.1min/mm.In order to prevent the "bubbling" phenomenon, the three stage depressurization process is usually adopted in the later stage of hot pressing. The first paragraph from the work pressure down to "balance pressure", the second paragraph from "balance pressure" down to zero, the third section from zero to hot plate completed the opening.
