The splint, also known as the plywood, and is known as the fine core plate. It is carried out by a three or multi-layer one millimeter thick panel or thin plate rubber. It is currently the most commonly used materials for handmade furniture.

 

Specification: specification
The splint is generally 2440 mm, which is 1220 mm wide, and the thickness is divided into three-pole, 5-pole, 9-chim, 12-chim, 15-chip and 18-chimmed six species (1% 1 mm). Of course, there are 21% and 25%, and the thickness can basically be produced according to different requirements.

 

Features: characteristic
First, the plywood has both natural wood all the advantages, light weight, high strength, texture, insulation, etc., but also make up for some of the natural wood naturally generated defects such as nuntees, small shape, deformation, and longitudinal differences. .
Second, the production of plywood production can be reasonably utilized for logs. Because it is not sawdust, each 2.2-2.5 cubic meters can produce a cubic mesh plywood, which can be used instead of approximately 5 cubic meters of raw wood saw, and each production of 1 cubic meters of plywood products can also produce 1.2-1.5 cubic. Rice, this is a good raw material for producing medium density fiberboards and particleboard.
Since the plywood is small, the formation is large, the construction is convenient, not warth, and the horizontal tensile mechanics is good. Therefore, the product is mainly used in furniture manufacturing, indoor decoration, and residential buildings. Secondly, there is a shipbuilding, car box manufacturing, various military, light industry products and packaging industrial sectors.

 

Process: crafts
The plywood is made of a single plate or a three-layer sheet metal, a three-layer or three-layer thin plates that are formed by the original wood. It is usually used to use an odd layer veneer and the fibers of the adjacent layer sheets are commonly arranged vertically. Therefore, there are three odd layer plywoods such as three, five, seven.
From the perspective of the structure, the outermost sheet of the plywood is called the table board, and the front panel is called a panel, which is a single sheet with the best quality. The surface plate of the reverse surface is called the back plate, with a single sheet of mass. The single sheet of the inner layer is called a core plate or a medium, consisting of a single sheet material with the worst mass.

 

Classification: classification classify
The plywood is divided into ordinary plywood (adapting to a widely used plywood) and a special plywood (capable of specialized use).
The quality requirements of the plywood include three contents of appearance, size, physical mechanical properties.
The appearance level, the size, and physical mechanical properties are qualified to determine the product as a qualified product, otherwise it is unqualified. When the plywood is exported, it should have the product quality identification certificate of the production plant quality inspection department, indicating the category, specifications, grade, glue strength and water content of the plywood.
(1) The specifications of the ordinary plywood have a thickness of 2.7 mm, 3.3mm, 4.5mm, 5.5mm, 6mm ... Since 6mm, press LMM to increment. The thickness is from 4 mm or less as a thin plywood. 3mm, 3.5mm, 4mm thick plywood for common specifications. Other thickness of the plywood should be produced after the agreement between the two parties.
.
The above four grades of panel stasis (scraping) light, special needs can not be sand (scrape) light or two sides (scrape) light. The sand-bearing plywood refers to a rubber plate having a sand light (or scraper) sand (or shaving). It is generally determined by the allowable defects on the plylets. The level is derived from the allowable material defect, processing defects, and requirements for stitching.
