| Abstract: | This artical presents the productive technology and formulae of urea-formaldehyde resin used in bamboo mould plate. The results showed: under better control condition of technology, the quality by three-time condensation plymerization is superior to that by two-time one; the best gram molecule ratio of formaldehyde to urea is 1:1.6, the amount of urea added by three-time is 70%, 20% and 10% respectively. |
