3种改性剂对大白藤的增强改性研究
Research on the enhanced modification of Calamus faberii by three modified reagents
摘要
Abstract
In order to improve the physical and mechanical properties of rattan,Calamus faberii was taken as the research object,MMA(methyl methacrylate),SBCPA(Si-Bi-Cd-Pb alloy)and FA(furfuryl alcohol)were se-lected as modified reagents.An orthogonal experiment was arranged at three levels,including four factors,namely,modifier,impregnation amount,treatment temperature and treatment time.According to the pre-experiment,the maximum impregnation amount of the specimen impregnated with MMA,FA and SBCPA were about 35％,70％and 200％,respectively.The results showed that the main physical and mechanical properties of the three modi-fied C.faberii were modified to different degrees,MOE(modulus of elasticity),MOR(bending strength),USCPG(compressive strength parallel to grain),SSPG(shearing strength parallel to grain)and BD(basic density)increased by 8.3％-64.2％,28.0％-107.6％,30.5％-94.4％,3.8％-32.1％and 32.1％-220.7％,respectively,while VSOD(volume over-dried shrinkage ratio)dropped by 19.6％-75.4％.A combination of factors determining the best process were as follows:the modified reagent was SBCPA,the impregnation amount was 195％,the treat-ment temperature was 105 ℃,and the treatment time was 2 h.According to the verification experiment obtained the modified material,MOE,MOR,USCPG,SSPG and BD were 4 350 MPa,181.2 MPa,77.8 MPa,12.3 MPa and 1.612 g·cm-3,and increased by 46.9％,102.9％,60.2％,12.2％and 221.1％,correspondingly;VSOD was 7.3％,down 27.0％from the material.EC(electrical conductivity)and LOI(limit oxygen index)also increased from 0 S·m-1 and 27.7％to 0.904 S·m-1 and 29.9％,correspondingly.In conclusion,after the modification treatment of SBCPA,the BD and main mechanical strength of C.faberii were significantly improved,the VSOD was sig-nificantly reduced,and the EC and LOI were also modified to varying degrees.关键词
