以棉秆为原料,经浸泡、蒸煮、搓磨分丝成纤维束,选择不同规格的棉秆碎料和不同比例的脲醛树脂胶,按照不同的目标密度,在设定的热压胶合条件下进行正交试验。通过KHQ-002H 木材和人造板自动万能力学试验机和FWDR 准稳态导热系数测试仪进行检测,得到静曲强度、弹性模量和导热系数等相关参数,再对其进行方案优化,得出工艺参数为密度0.4 g/cm~3、施胶量10%、棉秆丝长度规格为10 ~ 15 mm 的轻质碎料保温板的静曲强度、弹性模量和导热系数分别为13.3 MPa 、1 353 MPa 和0.134 w/m·℃。结果表明,低密度的棉秆碎料保温板导热系数接近或低于常用的建筑板材,具有良好的隔热保温性能,而且其力学性能能够满...

As a raw material, the cotton stalks are soaked, cooked, and ground to make fi ne fi ber bundles. Particles of different sizes made from cotton stalks are chosen and mixed with formaldehyde resin adhesive of different proportion. Orthogonal test is done under the setting of hot press gluing conditions according to different densities. Through the KHQ-002H wood and artifi cial board automatic universal mechanical testing machine and FWDR quasi steady thermal conductivity test instrument for testing, the static bending strength, elastic modulus and heat conduction coeffi cient and other related ...
