Abstract:
Penetration of aqueous polymer isocyanate (API) adhesive into Larch、 Birch and Oak with micrograph method was studied in this paper. The results showed that there was no difference in penetration between tangential direction and radial direction for each wood. In the tangential glued specimens, API adhesive penetrating into ray tissues was not observed even for Oak wood. That is to say, the ray tissues played no role in conducting liquid API adhesive into the three woods. Reasons for this phenomenon were analyzed also.
Key words: Aqueous polymer isocyanate(API) adhesives, Quarter-sawn board, Flat-sawn board, Penetration, Micrograph
