In order to improve the performance of starch and expand its application range, physical, chemical or enzymatic treatment is used to introduce new functional groups on starch molecules or change the size of starch molecules and the properties of starch granules, thereby changing the natural characteristics of starch and making it more suitable for starch. Certain application requirements. This kind of starch whose properties have changed after secondary processing is collectively referred to as modified starch.
In the paper industry, traditional starch was used as raw material to produce paper, but after modified starch came out, traditional starch was abandoned and modified starch was used. Why? In other words, where are the advantages of using modified starch in the paper industry?
First of all, modified starch is used in the paper industry, and the operation process is simple, non-polluting and non-corrosive;
Secondly, the paper made of modified starch has better performance and toughness, and the smoothness and surface strength of the paper are improved;
Furthermore, the price of modified starch is almost the same as that of traditional starch, with a wide range of sources and the effect of a viscosity reducer;
Finally, choosing modified starch as the raw material of paper is more economical than traditional starch, that is, the former can produce more paper with the same amount.
