蔗糖改性三聚氰胺-甲醛浸漬樹脂飾面三層楊木地板的研究

蔗糖改性三聚氰胺-甲醛浸漬樹脂飾面三層楊木地板的研究摘要：

本研究旨在探討蔗糖改性三聚氰胺-甲醛浸漬樹脂飾面三層楊木地板的性能和優(yōu)化生產(chǎn)工藝。研究采用實(shí)驗(yàn)室研究和現(xiàn)場(chǎng)實(shí)驗(yàn)相結(jié)合的方法，對(duì)三種不同配方的蔗糖改性三聚氰胺-甲醛浸漬樹脂飾面三層楊木地板進(jìn)行了性能測(cè)試和生產(chǎn)工藝優(yōu)化。測(cè)試結(jié)果表明，采用一定比例的蔗糖改性劑和甲醛樹脂，可以提高地板的硬度、抗拉強(qiáng)度和耐磨性，同時(shí)能夠減少甲醛釋放。經(jīng)過工藝優(yōu)化后，地板的制造效率得到提高，并且地板的質(zhì)量穩(wěn)定性得到了保證。
