        摘要：The authors developed a new technology for making laminated fibrillated-veneer lumber.They designed an experiment using bamboo（Bambusa distegia） to optimize the processing parameters.The effect of resin impregnation rate on mechanical performance and water resistance was discussed.The results showed that increasing specimen resin content from 7% to 13%,had a negative impact on the average modulus of rupture（MOR） and tensile strength,and a positive influence on the shear strength and water resistance.However,the increase in resin content didn’t affect the modulus of elasticity（MOE） or compression strength.The authors suggested that the panel’s mechanical performance and water resistance could be predicted by controlling the resin impregnation level to meet different application demands.

        摘要：The authors investigated how the four different preservatives（Zinc Borate,Ammoniacal Copper Quaternary,Copper Azole and Copper Naphthenate） affected Bamboo Oriented Strand Board（BOSB） decay resistance.BOSB samples were made in the laboratory with phenol-formaldehyde and diphenylmethane diisocyanate resins.The results showed that the preservatives,their loading level,and the adhesives had considerable influence on the sample’s decay resistance and that BOSB treated with the preservatives could meet the required anti-decay level of the Chinese National Standard GB/T 13942.1-92.

        摘要：Glue bonding quality is an important factor for bamboo flooring products.The Chinese National Standard Bamboo Flooring（GB/T 20240-2006） established the flooring bonding performance testing method by immersing specimens into 63 ℃ water for 3 hours and then drying them for 10 hours.The authors conducted an experiment to investigate the effect of drying time on flooring glue bonding performance.It was found that most bondline delamination occurred in the first three drying hours.Based on this observation,they suggested that the standard drying time should be shortened to 3 hours when the relevant standards were in revision.

        摘要：Okan flooring specimens were treated for four hours in a heating chamber with superheated steam and oxygen content less than 2 percent.The effects of treating temperature（160220 ℃） on specimen color were investigated.The results showed that as the temperature increased,the specimen color became darker.It was observed that the temperature impact on sapwood was more obvious than that on heartwood when the temperature was under 200 ℃.However,the sapwood and heartwood color tended to be the same when the treatment temperature was above 200 ℃.

        摘要：The authors investigated two solid wood floorings for abrasion resistance: one with an elastic coating and the other with a normal ultra-violet（UV） cured coating.The test results showed that the wood flooring with the elastic coating had better abrasion resistance than the one with the regular coating.The authors also found that the EN 14354-2004 evaluation procedure was more accurate for determining abrasion resistance of solid wood flooring with elastic coating than the GB/T 15036.2-2009 procedure.
