HCI로 침전 처리한 혈액으로부터의 혈분수지 제조 배합비에 따른 점도변이와 합판 접착력에 미치는 영향

The Effect of Adhesion strength and viscosity variation on the Blood glue combination ratio from HCI-precipitated Blood

This study was carried out to develop new wood. adhesive for the manufacture of plywood. It was the. new and simple, rapid method of isolation and purification of plasma proteins of HCl-precipitated pig bloods, furthermore because it was utilized waste bloods from slaughtered animals, It was able to prevent water pollution. Also This method was more economic than TCA-precipitated blood. HCl-precipitated blood glue will be a new wood adhesives in plywo The results are as follows: 1. The optimum viscosity range of HCl-precipitated blood glue was 7000-31000cps. Therefore the best combination ratio were water 44g, HCl-precipitated blood flour 5g, wood flour(#200) 1.4g, diesel oil O.5g, 50% NaOH 1.1g, Ca(OH)) O.47g and Sodium silicate 2.2g(D type). 2. Tensile-shear bonding strength of plywood manufactured by HCl-precipitated blood glue met a KS(korean standards) in the all combination factors. Also the combination ratio of the best tensile-shear bonding strength was the D type.
