Effects of Thermal Treatment on the Physical-mechanical Properties of Woodcut
摘要
Abstract
To improve the woodcut dimensional stability and processability,we selected elm timber (Ulmnus laciniata) as the test material to investigate the effects of high-temperature on the physical-mechanical properties and dimensional stability of the elm timber.The applicability of the treated timber to woodcut was discussed.The results showed that the hardness,abrasion resistance,wittability and moisture movement of heat-treated elm timber decreased with the increases of temperature and time.Treated at 220℃ for 2 h,all the indexes of the timber reached the standard for common woodcut.The heat treatment temperature and time had significant impacts on the hardness,abrasion resistance,pigment and water contact angle,tangential swelling rate,volume swelling rate and the hygroscopicity.The heat treatment also had significant impacts on the radial swelling rate.It was concluded that heat treatment on elm timber for woodcut could improve the dimensional stability,reduce the size variation during making and printing woodcut,and improve the accuracy of different blank overprint,which were favorable to realize the precision requirements of the artists for engraving on the details.关键词
