Description
Technical field
The present invention relates to plant fiber artificial board technology fields, and in particular to a kind of shinyleaf yellowhorn fruit shell antibacterial bacteriostatic is artificial multiple
Plywood and its manufacturing method.
Background technique
Shiny-leaved yellowhorn is the distinctive rare woody oleiferous plants crop in China, has flourishing root system, adaptable, and saline-alkali tolerant resists
It is cold, it can normal growth on meadow, wasteland, mountain area, gully and other places.Shiny-leaved yellowhorn whole body is all precious, branch, leaf, flower, fruit, kind
Son etc. can be used as medicine.In recent years, due to shiny-leaved yellowhorn industrial value with higher and nutritive value, increasingly by the pass of people
Note.The existing a large amount of plantation shiny-leaved yellowhorns in China, kernel is chiefly used in extracting oil, and shell is not effectively utilized as waste.
Recently it is main in shinyleaf yellowhorn fruit shell to have been reported that (Chinese grain and oil journal, the phase of volume 2012,27 11,118-121 pages) shows
Contain the substances such as flavones, saponin(e, cumarin, sterol, fatty acid.Wherein, flavones has the effects that anti-oxidant, anti-inflammatory, antiviral；
Saponin(e has good inhibitory effect to staphylococcus aureus and Escherichia coli.
Wood-based plate is centainly to be machined using timber or other non-wood plants as raw material and be separated into various unit materials
Afterwards, apply or do not apply adhesive and other additives it is glued made of plate or molded article.With moisture resistance, corrosion resistant, insect prevention
The features such as moth, is mainly used in shelf bed board, sleeper, Pu Liang, floor etc. that storage sector uses.Wood-based plate is raw materials used, removes
Glued board need to be with outside log, and major part is from felling and industrial wood waste and small dimension wood (diameter is at 8 centimetres or less).With
The fast development of building decoration and upholstery, domestic Wood demand sharp increase, the notch of wood supply are more and more prominent.Hair
Exhibition wood-based panel industry is conducive to alleviate China's timber imbalance between supply and demand, is the important channel for saving timber resources.
The industry of artificial boards development in China is rapider, and since 21 century, it is super that China's wood-based plate produces average annual growth
Cross 20%, it has also become the first big country of world's Wood-based Panel Production, consumption and foreign trade.2011, national industry of artificial boards was tired
Yield is counted up to 2.35 billion cubic meters；2012, the yield of national wood-based plate increased by 19.72% on a year-on-year basis up to 2.86 billion cubic meters.
The yield of national wood-based plate in 2014 is up to 2.73 billion cubic meters.
Increasingly extensive with wood-based plate application, in people's daily life, such as helping occur in more and more artificial plates
Hand, floor etc., therefore its antibacterial bacteriostatic performance should also become one of the performance requirement considered in material production.
