毛白杨制备LNG船用特种重组材料的适应性初步研究
Preliminary Study on the Adaptability of Special Wood Scrimber Materials for LNG Ships Prepared from Populus tomentosa
摘要
Abstract
The special scrimber for liquefied natural gas(LNG)ships is used as a load-bearing and insulation material between the cryogenic gas storage tankers and the ship hull.Currently,this material is mainly imported from abroad.In this study,Populus tomentosa veneers with thicknesses of 1.3 mm and 1.8 mm were used to prepare special wood scrimber for LNG ships.The microstructure,water absorption and mechanical strength were evaluated and compared.The results indicated that the performance of the special wood scrimber prepared from 1.3 mm veneers was superior,with a water absorption rate of 6.6%,vertical loading and bending resistance of 212.4 MPa and 17.5 GPa respectively,a compressive strength of 255.6 MPa,and a shear strength of 38.2 MPa.However,the shear strength and water absorption of wood scrimber-1.3 are still lower than those of imported products.Furthermore,during the mechanical strength test,it was found that the wood scrimbers prepared from two types of veneers were both crushed and exhibited some cracks.关键词
