Problems solved by technology

That is to say, the "viscosity" in the existing starch glue is only a fluidity index, rather than a bond strength index. Therefore, the bond strength of the existing starch glue is not high, and when the glue is applied to the production of cardboard, it is easy to False sticking or glue opening

Abstract

The invention relates to the technical field of glue, and in particular relates to application and a processing method of cassava whole flour. According to the method, cassava whole flour is used forreplacing traditional pure starch; the whole cassava flour containing the fibers is used for preparing glue, the prepared whole cassava flour glue is high in bonding strength, steam is saved, when thewhole cassava flour glue is used for producing paperboards, the phenomenon of false bonding or glue failure can be avoided, the fiber in the whole cassava flour is capable of effectively improving the compression resistance of corrugated paperboards, machine speed is increased, and paperboard processing quality is stable. A processing method of whole cassava flour comprises the following steps: impurity removing, wherein, cleaning and removing impurities on the surface of fresh cassava; slicing or shredding, and drying in the sun or baking, so that the moisture of the cassava is controlled within 15%; and crushing, wherein crushing the dry cassava or the dry cassava slices by using a crusher to obtain the whole cassava flour. The processing method of the whole cassava flour is simple andhigh in production efficiency, it is not needed to remove cassava residues in the whole cassava flour, waste is turned into valuables, the use amount of glue preparation raw materials is greatly reduced, and the processing cost of corrugated board production lines is reduced.

Description

technical field [0001] The invention relates to the technical field of glue, in particular to the application and processing method of whole cassava powder. Background technique [0002] The traditional cardboard glue is generally made of corn and tapioca starch as the main raw material, and the corn starch glue is composed of sodium hydroxide, reinforcing agent, borax and other auxiliary materials. Adapt to large-scale applications. However, the adhesive performance of cornstarch glue is still not ideal, and the adhesive effect of the cardboard products is poor, and it is not suitable for the high-speed production requirements of modern cardboard lines. The production of modern corrugated cardboard requires starch glue to have the following properties: 1. Environmental protection, non-toxic, odorless, and no pollution to the environment; 2. Improve the bonding strength and edge pressure strength of cardboard; 3. Suitable for high-speed production of modern cardboard lines ...
