The compression strength of pitch derived car. 将高温煤沥青和浸渍剂沥青在不同压力下炭化,在2500℃下对所得沥青炭进行石墨化处理;测试了所得沥青炭的体积密度、开孔率;利用扫描电子显微镜(SEM)观察了所得沥青炭的显微结构;利用XRD检测了所得沥青炭石墨化处理后的石墨化度;测试了所得沥青炭的压缩强度。 3....
For the light-weight closed-cell PVC foam tested in the study, an approximately linear relationship with the product of foam density and cell rise ratio was found for both foam compressive stiffness and compressive strength.AKIRA MIYASEKING HIM LO...
These results exhibited that in general, layered hybrid foams outperform conventional single-foamed materials in terms of compressive strength. Moreover, the natural frequency and damping ratio of the layered hybrid foams were investigated by vibration tests under clamped-free and free-free boundary ...
The results from SHAP indicate that the eccentric loading ratio (e/2a) has the most significant effect on the load-carrying capacity of elliptical CFST short columns, followed by the yield strength of the outer steel tube (fyo) and the inner width of the inner steel tube (2aii). ...
Concrete was produced using each of the above aggregate combinations, cast, cured and tested for compressive strength at maturity ages of 7, 14, 21 and 28 days. The results revealed that the gravel plus river sand aggregate combination had the highest packing densities both in the loose and ...
KRD101 series packaging compression tester is designed to evaluate the compressive strength of packaging in order to prevent the product from deforming or being damaged during handling, stacking, storage, and transportation due to insufficient packag...
2. Non deformation. Due to the density strength of the wooden plastic, the WPC door is hard strong, which is non deformation under any weather circumstance. WPC material can stay in the temperature of -40° +65°. 3. Various color and design selection. Our wpc door color treat...
