Study of in-situ gel polymerization established by Si-O-Si framework within wood micropores
2014 - IRG/WP 14-40672
Sodium silicate was used to form Si–O–Si framework by gel process and optimize the effect of the methylolurea impregnation on poplar wood. The modifier cured within the wood micropores by in-situ gel polymerization during the kiln drying. The results showed that treated wood acquired higher mechanical strength, but lower hygroscopicity. New positions of the XRD peaks appeared which caused by s...
