本文根据纤维素晶区和无定形区的概念,考虑羟基是具有电极矩的极性基因,算出羟基的电矩。用静电场理论,分析晶区单位体积羟基电矩的矢量和等于零,即不存在静电场力对极性水分子作用,使得水分不能进入晶区内;在晶区边界上,由于羟基电矩的有序分布,单位面积上电矩的矢量和不等于零,水分可以被吸着在晶区表面上。在无定形区,羟基电矩呈无序分布,具有净体电荷密度和面电荷密度产生的吸附静电力场吸附水分子,所以水分可以进入无定形区。这就是水分分布在晶区间和无定形区域的理由。
In this paper, based on the concept of cellulose crystalline regions and amorphous regions, we consider that the hydroxyl group is a polar gene with electrode moment, and calculate the hydroxyl moment. Using electrostatic field theory, the vector sum of the hydroxyl moment of the unit volume of the crystalline zone is analyzed to be equal to zero. That is, there is no action of the electrostatic field on the polar water molecule, so that the water can not enter the crystalline zone; on the boundary of the crystalline zone, In an orderly distribution, the vector sum of the torques per unit area is not equal to zero and moisture can be adsorbed on the surface of the zone. In the amorphous region, the hydroxyl moment is in a disorderly distribution, with the net charge density and surface charge density adsorption electrostatic field adsorption of water molecules, so water can enter the amorphous region. This is why water is distributed between crystalline and amorphous regions.
