项目摘要

This research was conducted during the three year period from 1994 to 1996. We made this inquiry becase tile makers are having a hard time producing tiles of high-level craftsmanship that do not fall off from outdoor walls. We experimentally examined the dynamic behavior of tiling with highly elastic adhesives, superior workability and good pliability. Although the adhesive strength of highly elastic adhesives is weak compared to mortar, we found that it is strong enough. And it was also made clear that because of the good pliability, the highly elastic adhesives efficiently prevented tile peel-off in use with ferroconcrete structures. Also, according to another organization, as a coating material, there is violet burning when the surface tiles or the joints fall off, and there is the gas problem. But compared to mortar, there is no big difference in performance. As for the last fiscal year, from the results and experience up to now, as we reexamined the method of evaluating the mutual … More behavior of the adhesive and the back of the tile (repetition-fatigue experiment) in mm units, we examined the development of the shortening of time taken for the experiments (impact tests), the method of simple experiments we were able to do at the place (twisting experiment), etc. As for the results, although the problem of deformation remained in the tests for fatigue, we have arranged the evaluations of the durability and adhesive strength. We dscovered that we could evaluate the small areas that the adhesive does not stick, etc., and that we could shorten the experimenting time very much with impact tests, and without using heavy equipment, we learned that the experimenting methodology of high precision impact tests was applicable. It is necessary to use this method in the future, obtain a lot of data, elevate the degree of precision and evaluation, and compare it to the conventional methods. Furthermore, the two year outdoor exposure experiments are still in progress. Follow-up experiments for this still remain to be done for next time. Less

这项研究是在1994年至1996年的三年期间进行的。我们之所以提出这个问题，是因为瓷砖制造商很难生产出不会从室外墙壁上掉落的高工艺瓷砖。我们用高弹性胶粘剂、优异的工作性能和良好的柔韧性对瓷砖的动态性能进行了实验测试。虽然与砂浆相比，高弹性胶粘剂的粘接强度较弱，但我们发现它足够强。研究还表明，由于高弹性粘结剂具有良好的柔韧性，有效地防止了钢筋混凝土结构中的瓷砖剥落。另外，据另一家机构介绍，作为涂层材料，当表面瓷砖或接缝脱落时，会出现紫色灼伤，还有气体问题。但与砂浆相比，在性能上没有太大差异。至于上一财年，从结果和经验来看，到目前为止，我们重新审查了相互…的评估方法在mm单位中，胶粘剂和瓷砖背面的更多行为(重复疲劳试验)，我们检查了缩短试验(冲击试验)所需时间的发展，能够在现场进行的简单试验(扭转试验)等。至于结果，虽然疲劳试验中仍然存在变形问题，但我们安排了耐久性和粘接强度的评估。我们发现，我们可以评估胶粘剂不粘的小区域等，我们可以通过冲击试验大大缩短试验时间，并且在不使用重型设备的情况下，我们了解到高精度冲击试验的试验方法是适用的。今后有必要使用这种方法，获取大量的数据，提高精度和评价程度，并与常规方法进行比较。此外，为期两年的户外暴露实验仍在进行中。这方面的后续实验还有待下一次做。较少
