查询词典 shear strength

Effects of dry temperature and dry time on properties of heat cured sand and the relationship with binder composition are as follows:sands bonded by binders that are not modified have high strength when dry temperature is high and dry time is long,but their anti-wettability power is poor . Sands bonded by binders that are modified by B but not modified by M can be dried quickly and sand strength is high but anti-wettability power is also poor. Sands bonded by binders that are modified by M but not modified by B can also be dried quickly to obtain maximum strength,then the strength becomes lower when they are dried continually for more time. and sand strength is high but anti-wettability power is also poor. Sands bonded by binders that are modified by M as well as by B at the same time can be dried quickly to obtain maximum strength at low temperature and short time. But the anti-wettability of sand mold is best when they are dried at high temperature and long time.

烘干温度和烘干时间对热硬砂性能的影响及其与粘结剂改性的关系是：未经改性剂B和改性剂M改性的粘结剂砂，脱水速度较慢，烘干温度越高，时间越长，则硬化强度也越高，但未经改性的粘结剂热硬砂的抗吸湿性较差；经改性剂B而不经改性剂M改性的粘结剂热硬砂，烘干硬化速度较快，强度也高，但在高湿度下的抗吸湿性不好；经改性剂M改性而不经改性剂B改性的粘结剂热硬砂，烘干时强度先随烘干时间升高至最大值后，继续烘干时强度又出现下降；经改性剂B和经改性剂M共同改性的粘结剂热硬砂能在短时间和较低的烘干温度下就可烘干到最高强度，即烘干脱水的速度较快，但试样的抗吸湿性差，若在更高温度和更长时间下烘干，试样的抗吸湿性得到改善，综合考虑烘干强度和抗吸湿性要求，对于φ30×30mm试样，理想的烘干温度是200℃，烘干时间20分钟。

Through comprehensive comparison,during the growth from 1 age-degree bamboo to 2 age-degree bamboo,density, mechanical strength(except maximum tensile strength etc.),fraction of bundle sheath,cell wall ratio,crystallinity,cellulose content and lignin content increase rate are the greatest.3age-degree bamboo has higher strength,strength and gravity ratio andcrystallinity are the biggest,fraction of parenchyma is small and insect-resistant.2 degree bamboo has the greatest mechanical strength,but its strength andgravity ratio is not the highest and its crystallinity is lower than 3 age-degreebamboo due to its greatest fraction of parenchyma,loss tangent value is thebiggest.Its creep character is not good and is easily eaten by moth.

通过综合比较，竹材从1度竹到2度竹生长过程中，密度、力学强度、纤维束比量、胞壁率、结晶度、纤维素含量、木质素含量等指标增加幅度是最大的。3度竹强度较高，强重比、结晶度最高，薄壁组织含量较小，相对抗虫蛀，材质最好，适合材用。4度竹结晶度下降引起强度的下降，但薄壁组织组织比量最小，相对最抗虫蛀。2度竹力学强度最大，但是强重比并不是最大，结晶度比3度竹低，由于薄壁组织组织比量最大，内耗值最大，蠕变性能较差，同时相对易遭虫蛀。

UHMWPE has regular molecule chain and lower shear strength, so it improved the tribological property of PA66. When the amount of the transferring layer reached a certain value, severe plastic distortion and adhesion wear occurred, and wear resistance of the blends was related to the mechanical property of the blends. Worn microstructure changes with addition of compatibilizer. Soft UHMWPE produced from friction heating has low shear strength, and it improves the tribological property of PA66 during the friction course.
