Factors of Adherence Cavity


Factors of adherence cavity can generally be assorted into 2 groups. The first one is anthropogenic reasons, which include the neglect of standard process that is designed to prevent adherence cavity, the bad skill of installation, etc. These reasons can all increase the possibility of occurrence of adherence cavity. The other one is all kinds of natural factors, inculding the essential charateristic of construction material and adhesive themselves, come-and-go affected by change of temperature and humidity, earthquake and vibration from tread, etc. In the long run, these factors will force the adherence cavity come into existence on the interface level between construction material and adhesive. Compared with anthropogenic factors, natural factors may rarely be emphasized; however, they are the essential reasons that adherence cavity occur in the future.


Anthropogenic factors can be gradually removed through quality control, new equipment adoption, and skill training. The installation can be improved toward perfect to avoid adherence cavity happens right after the complete of installation. However, no matter how good the skill is, now perfect the installation is, it can not be promised that cavity will not come into being in 3 months, and do need to mention longer than 3 months. The situation just described, in brief, result from natural factors. Among all kinds of natural reasons, the essential characteristic of construction material and adhesive themselves is the critical factor. If there is no good procedure to handle it, even without come-and-go or vibration from tread, adherence cavity will soon come into existence.
