| 這可能是改性劑通過浸漬進(jìn)入木材內(nèi)部后,改性劑大分子與木材細(xì)胞壁大分子上的羥基發(fā)生縮合反應(yīng),減少了木材內(nèi)部大分子上的羥基官能團(tuán)含量,顯著降低了楊樹木材的親水性,從而降低了木材的吸水性能,改善了其濕脹和干縮的性能,使得其尺寸穩(wěn)定性得到提高。 |

It could be the condensation reaction between modifier macromolecules and hydroxy of the wood cell wall macromolecule after modifier impregnated into the internal wood and reduced the hydroxyl functional groups content of the macromolecule inside the timber,which significantly reduces the aqueous affinity of poplar wood and aqueous absorbency of the wood. The wood swelling and shrinkage properties thus improved ,and so is its dimensional stability . 供參考! |
