| summary(En) : | In this paper the writers wish to report the results obtained from studies on the gluing strength and water resistance of plywood glued with solutions having pH of the isoelectric points of blood proteins such as albumin (isoelectric point, pH 4.8), globulin (isoelectric point, pH 5.4), and hemoglobin (isoelectric point, pH 6.4), and with solutions having pH of both sides of respective isoelectric point as above mentioned. Moreover, the writers experimented to ascertain whether the gluing strengths of serum glue and defibrinated blood glue had any influence on pH of the isoelectric points of the above mentioned proteins or not. The samples used in these experiments were dry powders separated from horse blood. The results obtained from these experiments were as follows: 1) The solution having pH of the respective isoelectric point of the blood proteins such as albumin, globulin and hemoglobin have higher gluing strength and water resistance than the solution having pH of both sides of the respective isoelectric points. 2) It seems that the gluing strength of serum glue and defibrinated blood glue are not influenced by pH of each isoelectric point of the proteins. 3) The writers noted that the defibrinated blood glue seems to have as high a gluing strength in the acid side as seen in the alkali side. |
