摘要

在这项研究中，用牛油果木通过卡夫法生产的纸浆制作了床单。原材料由一个果园提供，由鳄梨（Persea americana Mill.）树组成，这些树已经完成了使用寿命，并在日常疏伐维护过程中被砍伐。为了确定通过卡夫法由鳄梨木生产果肉的理想烹饪条件，通过改变烹饪时间（T）、活性碱（AA）和硫化度（S）的比例进行了16次烹饪。对纸浆的一般性能，特别是筛出浆率、纸浆粘度和Kappa值进行了评价。纸浆产量是确定蒸煮条件的主要依据。通过考虑纸张的一些物理、机械和光学特性，确定了理想的烹饪条件。根据这项研究，通过卡夫法从鳄梨（Persea americana Mill.）木材中生产果肉的理想条件是：18%AA、22%S和75min T。

Determination of Ideal Cooking Conditions for Pulp Production from Avocado Wood (Persea americana Mill.) by Kraft Method

In this study, hand sheets were made from pulp produced by the Kraft method using avocado wood. The raw materials were supplied by a fruit orchard and consisted of avocado (Persea americana Mill.) trees that had completed their useful life and were cut during routine thinning maintenance. In order to determine the ideal cooking conditions in the production of pulp from avocado wood via the Kraft method, 16 cooks were carried out by varying the cooking time (T), active alkali (AA), and sulfidity (S) ratios. The general pulp properties, especially the screened pulp yield, pulp viscosity, and Kappa number, were evaluated. The pulp yield was taken as the primary basis in determining the cooking conditions. The ideal cooking conditions were also determined by considering some physical, mechanical, and optical properties of the paper. According to this study, the conditions found to be ideal in pulp production from avocado (Persea americana Mill.) wood via the Kraft method were: 18 % AA, 22 % S, and 75 min T.
