Abstract:

An  adhesive  bonding  technology  is  a  prospective  bonding  technology  of  diverse materials.  For  successful  practical  application,  knowledge  gained  by  studying  factors  that significantly influence mechanical properties of the adhesive bonds are essential. The adhesive bond  rise  is  influenced  by  an  increase  of  chemical  –  physical  links.  The  adhesive  bonding strengthens its position in a number of agricultural machines and tools.  The aim of the experiment is to create the adhesive bond which provides the maximum strength and  quality  for  single  combination  of  the  adhesive  and  adherents,  usually  at  minimum  costs. This aim can be reached by describing the process of the hardening and ensuring the optimum adhesive  layer.  Describing  the  adhesive  bonding  process  and  its  factors  is  essential  for companies producing agricultural machinery. From the results of the experiment there is visible a significant fall of the tensile shear strength of  the  adhesive  bond  with  increasing  time  needed  for  the  adhesive  bond  creation.  The experiment  results  also  certified  the  negative  influence  of  the  unequal  adhesive  layer  on  the strength fall but also a huge dispersion variance of results.
