印刷公司紙張的主要原料

以木材(針葉木、闊葉木)、非木材(稻麥草)、廢紙等為原料,經過化學法制漿、化學機械法制漿、機械法制漿、廢紙脫墨等制漿工藝得到紙漿。紙漿是造紙的主要原料。

因制漿方法的不同,紙漿分為化學紙漿、化學機械紙漿、機械紙漿、廢紙紙漿等幾種紙漿。

因使用的制漿原料的不同,紙漿分為針葉木紙漿、闊葉木紙漿、非木材紙漿、廢紙紙漿等。

木材和非木材的主要化學成分是纖維素、半纖維素和木素。

化學紙漿主要成分是纖維素和部分半纖維素。

機械紙漿主要成分包含纖維素、半纖維素和木素。

化學機械紙漿主要包含纖維素、半纖維素和木素,但是它的木素含量少於機械紙漿。

針葉木紙漿的纖維長度比闊葉木的長,闊葉木的纖維長度比非木材(稻麥草)的長。
