摘要：本論文主要研究竹子的化學(xué)成分對(duì)漿得率的影響，論文的數(shù)據(jù)通過實(shí)驗(yàn)室做實(shí)驗(yàn)得到。實(shí)驗(yàn)所用的材料為某竹簾廠的毛竹邊角料和新鮮毛竹。實(shí)驗(yàn)中，對(duì)竹材的水分、灰分、苯-醇抽出物、木素及綜纖維素等含量進(jìn)行分析，經(jīng)比較，毛竹邊角料的木素含量高于新鮮毛竹4.26個(gè)百分比，綜纖維素的含量卻比新鮮毛竹低4.4個(gè)百分比。本實(shí)驗(yàn)采用硫酸鹽法對(duì)竹材進(jìn)行蒸煮，把蒸煮后的漿制漿板，測(cè)得粗漿得率及卡伯值，把新、舊兩種竹材的實(shí)驗(yàn)數(shù)據(jù)進(jìn)行比較。經(jīng)過上述數(shù)據(jù)綜合分析比較，毛竹漿的木素含量對(duì)其漿得率影響最大，也可得出舊竹材即廢棄的邊角料在制漿造紙方向有一定的利用價(jià)值，但不適合生產(chǎn)高檔紙，而可以用于一些白度要求不高的生活用紙。

Abstract: This paper mainly studies the influence of chemical composition on bamboo pulp yield, and the data obtained by laboratory experiments. The materials are the Waste of Phyllostachys pubescens from bamboo curtain factory cutout and fresh Phyllostachys pubescens. The bamboo’s moisture, ash, benzene - alcohol and lignin content are analyed in laboratory. By comparison, the lignin content of Waste of Phyllostachys pubescens is 0.426 percentage points higher than fresh Phyllostachys pubescens, but the Holo-cellulos content in fresh Phyllostachys pubescens is 4.4 percentage points lower.In this experiment, we use the Kraft pulping cooking. The pulp obtained after cooking is made into pulp board, then measure the pulp yield and Kappa number.Through the comprehensive analysis of the data, bamboo pulp of lignin and content on the slurry ratio, also can draw the leftover material is abandoned old bamboo pulp &paper direction in certain value, but it is not suitable for producing high-grade paper, but can be used in the whiteness paper for daily use.
