(For beginner) white birch Plywood knowledge& Manufacturing Experience Part 1 :  white birch face veneer

Here,we only talk about the birch species ,will not talk about the face veneer manufacturing defects and manufacutirng process and other specifications ,next POST will be talked about the birch veneer .

White birch plywood,the most popular wood species to the North America ,especially to the USA ,sure more than 95% of the plywood to the USA are white birch .They imported them for many different uses ,such as furniture ,cabinets ,packing ,flooring and industrial use and decorations …

So ,the white birch face veneer used for the plywood are the most important materials ,will decide the final quality and first impression of the quality by the buyers or the QC .Let ‘s have a general idea about the white birch wood species ,then we will talk about he white birch face veneers.

Different birch species ,different natural characteristis and different quality and dense ,in the cold area ,the birch grows slower than in the hot weather ,so dense will be …and also the wood grain of the different birch species ,mineral streaks ,knots and knot holes,pin knots and color variations …other types of the natural characteristics …

Common Name(s):

English Silver Birch, Weeping Birch, Common Birch, European White Birch
French Bouleau Pleureur
Spanish Abedul

Trees from the extremes of the distribution in Europe (Betula pendula), northeast Asia and Japan and western North America (B. platyphylla, B. mandshurica, B. neoalaskana) and southwest China and Tibet (B. szechuanica) look different and can be distinguished from one another. However, when the whole continuous geographical range of diploid silver birches is considered, all those named as species intergrade in geographically intervening areas. It is thought to be best divided into three subspecies, ssp. pendula in Europe and eastwards to central Asia, ssp. mandshurica in eastern Asia and western North America and ssp. szechuanica in western China from Qinghai and Gansu to Yunnan and southeast Xizang. Betula platyphylla has been described as a seperate species, representing birches from Mongolia east of the Altai and into western and northeastern China but it is thought the two are synonymous. Betula oycoviensispreviously listed as threatened is a form of B. pendula. Betula pendula ssp. font-queriand B. pendula ssp. parvibracteata, previously listed as threatened are thought to be only minor variants of B. pendula. Betula szaferi, described previously as Extinct in the Wild, is now considered a weak growing, precociously and heavily fruiting form of B. pendula, due to the presence of a mutant gene
