Manufacturing method of bamboo chip for manufacturing the solubility pulp and thereof

Abstract

There are provided a method for manufacturing a bamboo chip for a soluble pulp and a bamboo chip manufactured therefrom, the bamboo capable of improving their productivity and obtaining high-quality products, as well as manufacturing the soluble pulps economically and environment-friendly. The present invention provides a method for manufacturing bamboo chips including steps of: softening bamboo stems and giving bulkiness in a process of manufacturing bamboo chips by pressing and crushing the bamboo, which has compact and structural characteristics in nature, with a convex roller to tear the bamboo stems into pieces in a longitudinal direction, and simultaneously cutting the bamboo stems into bamboo chips having desired lengths; removing a large amount of unnecessary substances, such as lignin, thin- wall tissues, joints, silicified barks and the like, in celluloses in the above-mentioned process so as to facilitate easy penetration of chemical agents and effectively remove lignin and hemicellulose in a process for extracting a pulp; and pressing and bending the bamboo chips into certain shapes to package the bamboo chips, and transporting the bamboo chips to a container or a bulk carrier in an economic manner.

Description

technical field [0001] The present invention relates to a kind of manufacture method of bamboo chip and the bamboo chip manufactured according to this method, particularly a kind of bamboo chip manufacturing method that can improve productivity and obtain high-quality product, can economically manufacture soluble pulp and environmental protection, and Bamboo slices manufactured according to the method. Background technique [0002] [02] In general, the natural bamboo fiber without going through the dissolution process is directly developed as a non-woven fiber. Similarly, pulp for papermaking is used as a raw material for tissue paper and hygiene products (wrapping paper, cosmetic paper, cosmetic paper, sanitary napkins, diapers, etc.), and pulp for dissolving is used as chemical fiber, cellophane, plastic products, various fibers Raw materials for vegan derivatives (for example, viscose fibers, viscose staple fibers, etc.). [0003] [03] Therefore, the present invention p...

Problems solved by technology

However, adding too much cooking chemicals will cause environmental pollution, the increase of cooking temperature and the extension of cooking time will increase energy consumption and also cause damage to alpha cellulose

[0014] [14] In addition, due to the huge investment in equipment required for large-scale production, the production cost is increased, and because redundant parts such as bamboo, lignin, parenchyma and silicified bark are introduced into the cooking process, it is difficult to extract high-quality alpha cellulose in the process of making bamboo chips

[0015] [15] In addition, since the divided bamboo chips are difficult to stack, store, and package in transportation, the transportation cost of bamboo chips in containers is high, and it is difficult to invest in additional equipment for transportation of bulk carriers and reduce the use of bulk carriers

Not only that, due to the growth of fungi and bacteria, it is also difficult to produce products of uniform specifications, and it is also difficult to store bamboo chips
