輸入闊葉樹材의 pH 및 Buffuring Potential이 尿素樹脂接着劑의 Gel시간에 미치는 影響

Impact of Ph and Buffering Potential of Imported Hardwood on the Gelation Time of Urea-Formaldehyde Resin

The pH and buffering potential for water extract of eight imported hardwoods were determined. A pH range of 3.608 to 5.831 was found. The gelation time for a urea-formaldehyde resin for each wood was determined. Result shows that gelation time of a urea-formaldehyde resin was directly correlated to the pH and inversely correlated with acid-buffering potential for eight hardwoods aqueous extracts.
