Embodiment 1

[0041] A method for preparing paper pulp from water lotus, comprising the following steps:

[0042] (1) Mix the water lettuce and boiling water, immerse the water lettuce in the boiling water, the volume ratio of the water lettuce to the barrel is <60%, first beat at a slow speed for 2 minutes, then beat at a medium speed for 2 minutes, and finally beat at a high speed for 3 minutes obtain fiber pulp;

[0043](2) separating the fiber pulp of step (1) to obtain crude fiber pulp A and beating water;

[0044] (3) rolling the crude fiber pulp A described in step (2);

[0045] When the mass percentage of cellulose in the beating water in step (2)>50%, separate the beating water to obtain crude fiber pulp B and water, and the crude fiber pulp B is sent to step (3) for rolling, and after the water is heated Sent to step (1) for recycling, slow speed, medium speed and high speed are respectively 150rpm, 250rpm and 600rpm. The crushed pulp is sent to the pulp storage tank for storag...

Abstract

The invention provides a method for preparing paper pulp by means of water lettuce. The method comprises the steps of mixing the water lettuce and boiled water, performing variable-speed beating for obtaining beaten liquid, and separating the beaten liquid for obtaining the fiber paper pulp, and performing rolling. According to the method of the invention, boiled water variable-speed beating is utilized in a beating process, thereby effectively improving quality and efficiency in beating. In the pulp preparation process, a water and slurry separation water recycling technique is utilized; no waste water discharge is realized; adding of other chemical additives is not required; cost reduction is realized, and environment safety in a processing process is improved. According to the method ofthe invention, full branch of the water lettuce is used for producing the paper pulp for water holders, thereby alleviating or even settling a problem of no commercial value of the water lettuce, andreducing loss of a government in collecting and burying the water lettuce at aspects of manpower, financial resource and environment.

Description

technical field [0001] The invention belongs to the technical field of papermaking, and in particular relates to a method for preparing pulp from water lotus, the prepared pulp and its application. Background technique [0002] In the packaging of agricultural products, industrial products, ceramics, household appliances, cosmetics and food and drink, many of the existing packaging still use foam products, which will cause environmental pollution. Pulp products will not pollute the environment because they can be degraded. With the use of pulp molding technology, pulp lining can be formed at one time, and its technical indicators such as function and appearance can be comparable to and replace foam products and other lining packaging. [0003] Pulp is the raw material for the production of various paper products. With the increasing use of pulp lining and its positive effect on environmental protection, more and more pulp raw materials have been developed. Water water lotus...
