The activated carbon from bamboo shavings shows different quality by the methods of steam activation, phosphoric acid-spinning stove and phosphoric acid-microwave.
以竹刨花为原料,水蒸气物理法、磷酸转炉法和磷酸微波法生产出的活性炭各有特点,物理法的碘值高,但焦糖脱色率很小;两种化学法 3项指标都比较好,其中亚甲基蓝脱色力和焦糖脱色率都超过了国家一级品标准。
Under the microwave,the activated carbon from bamboo shavings was prepared with the phosphoric acid according to orthogonal tests.
在竹材加工过程中 ,出现很多竹刨花、竹屑副产品 ,企业一般弃之作燃料 ,如果将竹刨花制成活性炭 ,不仅可以变废为宝 ,实现资源再利用 ,提高企业效益 ,还将缓解活性炭在国内外供不应求的局面 (张齐生 ,1 995 ;2 0 0 2 )。
Powdered active carbon was prepared by H_3PO_4 activation method from bamboo shavings.
以竹篾、竹席加工的刨削剩余物———竹刨花为原料 ,采用磷酸活化法制取粉状活性炭产品 ,制备过程为 :竹刨花烘干后加入活化剂磷酸溶液 ,搅拌均匀后放置 2 4h ,然后移入高温电阻炉中进行炭化和活化 ,经水洗回收磷酸后烘干、粉碎制得粉状活性炭产品。
In order to develop an environmental friendly bamboo particleboard with bio-based adhesive,effects of coating ratio of soy protein adhesive modified by sodium dodecyl sulfate on the physical and mechanical properties of bamboo particle board were studied.
为了开发生物质胶黏剂及环境友好型竹刨花板,研究了基于十二烷基硫酸钠改性的大豆蛋白胶黏剂施胶量对竹刨花板物理力学性能的影响,结果表明,大豆蛋白胶黏剂的较佳施胶量为13%。
A series of experiments on determination of manufacturing technology for bamboo-based waferboard bonded with powdered phenol-formaldehyde (PF) resin were conducted by the authors.

showed that the effect of mold-proof treatment on bamboo-based waferboard (BWB) with alkyl ammonium compound (AAC) was better than that with boracic acid (H3BO3) and the higher concentration of the dosage, the stronger effectiveness; the mold-proof property of the anti-Penicillium sp.
对竹大片刨花板(BWB)作防青霉处理的试验结果表明:烷基铵类化合物(AAC)防霉剂的抗霉性大于硼酸,且药剂浓度越大则抗霉性越好;防霉剂对青霉菌的抑制效力随时间的延长而逐渐下降;无论酚醛树脂(PF)还是脲醛树脂(UF)对青霉菌基本无抑制作用;AAC表面处理和内部处理赋予竹大片刨花板的抗霉能力基本相同;烷基铵类防霉剂对PF-BWB的力学性能影响不大,但会导致UF-BWB力学性能的大幅下降。
