The Study On Quality Assesses And Examination Methods Of Rattan Furniture

On the basis of the research on the main characteristics of rattan materials and the general situations of rattan furniture, this dissertation studied deeply on the quality assesses of rattanfurniture. With the main research object of the rattan furniture, it consisted of three parts——the quality assesses and test methods of the appearance performances, the mechanical properties of the typical component parts and joints, and the mechanical properties of the holistic products. This systemic, exploratory research provided a basic and technical reference for establishing the standard of assessing rattan furniture quality. At present, this standard has been sent for examining and revising. Simultaneity, the research will also contribute to the more excellent designs of rattan products in the enterprise, and enhance our products' quality and competitive power in the world.The main research results are as follows:(1) The dissertation analyzed and generalized the basic conditions of the rattan furniture, rattan cane and its derivatives (materials for weave).The moisture content, the axial tensile strength, and mildew resistance of the rattan peel and the rattan core of Calamus simplicfoilius Wei. (one rattan species) have been tested: The rattan peel and the rattan core have approximate moisture contents (between 10%～11%), and they also the fine weaving materials .With the similar sizes, the axial tensile strength of the flat peel is better than the flat core; the axial tensile strength of the peel is better than the flat core; Among the three kinds of the rattan core, the axial tensile strength of the half-round core is the best. The mildew resistance of the weaving surface made of the rattan core is better than the one made of the flat peel.(2) The characteristic of the quality assess of the appearance performances is the research of the quality assess of the layout in weaving surface: The gap margin and distance margin for the close-grid and open-grid surface were referred as the indexes of dimension. The smaller the margins are, the finer the quality of the layout in weaving surface is.(3) The study on the mechanical properties of the typical component parts and joints will provide a good reference for the research of the mechanical properties of the holistic products.1) Weaving surface is a typical component part with good flexibility. In the condition of similar or same size, the flexing resistance of the close-grid one is better than the open-grid one; the flexing resistance of the close-grid one made of the rattan flat peel is better than the one made of the core; the flexing resistance of the weaving surface made by machine is better than the one made by hand.2) T-type and L- type are the typical forms of the rattan furniture joints. The results from the orthogonal tests and the variance analysis have showed that: the connections, the wrapping methods, the wrapping materials, and the species of the rattan cane all have significant effect on the tensile strength and bending strength of T-type joint. Correspondingly, the wrapping materials have smaller effects on the tensile strength, and the species of the rattan cane have smaller effect on the bending strength. Otherwise, the angle-wrapping miter L-type joint has the best bending strength, the bending strengths of the other two forms of L-type joint are relatively poor.(6)A mass of the feasibility tests have showed that: the quality assesses and test methods of the mechanical properties of the holistic products can refer to the corresponding contents in the national standard named "GB/T 10537.1～10537.6 Test of Mechanical Properties of Furniture". Only the loading times in durability tests need to be modified.
