\n<\/em>Neohouzeana dulloa<\/span><\/em> constitutes one of the valuable forest product resources. N. dulloa<\/em> Culms are used in many fields such as building, handicrafts and fine-handicraft production serving consumption domestically as for export. This bamboo is however easily damaged by biological agents diminishing its quality as a raw material. In production at present this bamboo must be submerged in ponds or lakes for 3-4 months, causing water pollution. Prompted by this fact a research subject is carried out: “Research on selecting preservatives and preservation technology to preserve N. dulloa<\/em> as raw material in production of handicraft and fine-handicraft commodities serving consumption in home country and export” aimed at raising product quality, saving production time, contributing to mitigating water pollution in handicraft villages, and enhancing production.<\/span>\n<\/p>\n

\nMaterials and methods<\/span><\/em>: Neohouzeana dulloa<\/em> as raw material; Forest product preservatives LN5, XM5, cislin; Application of testing procedure to evaluate the efficiency of preservatives against moulding fungi and pest insects in conformity with domestic and international standards.<\/span>Research on selection of preservatives for preservation of N. dlloa as a raw material<\/span><\/em>\n<\/p>\n

\n<\/em>– Cislin is effective against borers of N. dulloa<\/em>, suitable for preliminarily treating the raw material. <\/span>\n<\/p>\n

\n– XM5, LN 5 are effective for preventing attack by moulding fungi and insects damaging N. dulloa<\/em> at 5% concentration, under submersion for 7 days.<\/span>\n<\/p>\n

\nResearch on capacity of preservative absorption of  <\/span>N. dulloa<\/span><\/em>.<\/span>XM5, LN 5 are well absorbed when used at 5% concentration and submersion time is 7 days.<\/span>Research on impact of preservatives on mechanical, physical properties and color of N. dulloa<\/span><\/em>\n<\/p>\n

\n<\/em>– The effect of XM5, LN 5 on bending strength as well as shear strength and at glue joints of N. dulloa<\/em> is inconsiderable.<\/span>– The color of N. dulloa<\/em> impregnated with LN5 is little changed and LN5 can be used to preserve the handicraft commodities of required natural color.<\/span>\n<\/p>\n

\n– The color of N. dulloa<\/em> samples impregnated with XM5 is much changed as compared with LN5 thus it can be used for pr<\/span>eservation of handicraft commodities that need dyeing.<\/span>Research results show that XM5, LN5 are suitable for use in handicraft commodities production at 5% concentration, submersion in 7 days, preventing damage by biological agents such as moulding fungi, termites and borers.<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"
