Cassava Modified Starch Used in Paper Making Acetylated Distarch Phosphate

Cassava acetylated distarch phosphate starch is a kind of modified starch widely used in paper industry. It comes in the form of a white or yellowish powder that is odorless, tasteless and easily dissolves in water. The main function of this compound is as a thickener, binder and paper enhancer, providing specific viscosity and paper properties for the paper making process.

Cassava acetylated distarch phosphate starch is made through a chemical modification process, in which cassava starch is acetylated and phosphorylated to change its molecular structure and properties. This modified starch has higher reactivity and stickiness, providing greater thickening properties, adhesion and paper strengthening effects.

In the paper industry, cassava acetylated distarch phosphate starch is mainly used in the production of various papers and paperboards. As a thickener, it can improve the viscosity and consistency of the pulp and help to form a uniform paper structure. As an adhesive, it can effectively improve the strength and durability of the paper, making the paper more flat and ductile. As a paper strengthening agent, it can improve the tensile strength and folding resistance of the paper, making the paper tougher and more durable.

Compared with other thickeners, binders and paper strengtheners, cassava acetylated distarch phosphate starch has some unique advantages in the paper industry. First, because it is extracted from renewable cassava resources, it is environmentally friendly and sustainable. Secondly, cassava acetylated distarch phosphate starch has higher reactivity and thickening properties to provide stronger adhesion and better paper strengthening effects. In addition, it also has certain emulsifying properties, which can effectively stabilize the pigments and fillers in the pulp and improve the uniformity and smoothness of the paper.

It is worth noting that although cassava acetylated distarch phosphate starch plays an important role in the paper industry, some problems also need to be noted in the use process. For example, due to its obvious thickening effect, improper operation may cause the pulp to be too thick and affect the processing efficiency. In addition, the amount of cassava acetylated distarch phosphate starch needs to be strictly controlled too much or too little may have adverse effects on the performance of the paper.

Overall, cassava acetylated distarch phosphate starch is an effective papermaking thickener, binder and paper strengthening agent capable of providing good strength, durability and surface quality for paper. In the process of use, it is necessary to pay attention to its characteristics and reasonable control of the addition amount and operating conditions to ensure the stability and consistency of the quality of the paper, but also to consider the sustainability of its raw materials and the reliability of the source to ensure the sustainable development of the product.
