Embodiment

[0016] A method for utilizing bagasse pulp to produce translucent paper, comprising the steps of:

[0017] (1) Take 50 parts by weight of bagasse pulp and beat it with a medium-consistency refiner;

[0018] (2) Take 50 parts by weight of softwood pulp and beat it with a double-disc refiner;

[0019] (3) Send the bagasse pulp in step (1) and the wood pulp in step (2) to the pulping machine for pulp mixing, and add wet strength agent and water resistance agent at the same time, the amount of wet strength agent added is bagasse pulp and wood pulp 1.5% of the mixed pulp, and 0.3% of the water resistant agent added to the mixed pulp of bagasse pulp and wood pulp, and then pumped to the forebay for papermaking.

[0020] (4) Make paper with a paper machine according to the conventional method, and rewind and organize it with a rewinder;

[0021] (5) Re-moisten the rewinded paper sheets with warm water at 60 degrees Celsius through a humidifier;

[0022] (6) Use a super calender to...

Abstract

The invention discloses a method for producing translucent paper by utilizing bagasse pulp. The method comprises the following steps: the bagasse pulp is used as a main raw material and is mixed with partial coniferous wood pulp; and a wet strength agent and a water repellent agent are added to the mixing pulp, wherein the translucent paper comprises the following parts by weight of components: 50 to 60 parts of the bagasse pulp and 40 to 50 parts of wood pulp. Compared with the prior art, the method has the advantages that the quality of the translucent paper is ensured and the consumption of wood materials is reduced, so that the production cost is lowered.

Description

technical field [0001] The invention relates to papermaking, in particular to a method for producing translucent paper from bagasse pulp. Background technique [0002] It is well known that translucent paper must have certain characteristics such as moisture-proof, oil-proof, compactness and high transparency, and the production of translucent paper must adopt a process route of high beating degree (pulp treatment degree) and super calendering finishing of base paper. Therefore, the traditional production method of translucent paper is to use a large amount of long-fiber (coniferous) wood pulp and a small amount of short-fiber (broad-leaf) wood pulp as raw materials for pulping. Because the proportion of wood pulp used is large, the entire production cost is high and wood consumption is high. large, disrupting the ecological balance. Have not yet seen the report of utilizing bagasse pulp to produce translucent paper at present. Contents of the invention [0003] The purp...
