The primary study of effect factors on the free starch content of sweetpotato granulesindustry;

In order to prevent cell broken during the processing of sweet potato granules,to reduce the content of free starch,the breaking force,the content of cell free starch,the sensory evaluation of cell broken in different conditions were studied,and the mechanism was analysed.

Study on the flocculation performance of cationic starch in dyeing wastewaters;

Synthesis of quaternary ammonium type low substituting degrees of cationic starch;

The strengthening effect of PUS_01 anionic starch used in Masson's pine branch pulp has been studied,and the optimal charge has been set up.

This paper focus on the study on anionic starch-aluminium as well as anionic starchformaldehyde combination tannage to manufacture wet-white leather.

The interaction mechanism of anionic starch in flotation separation of diaspore and illite from bauxite has been investigated by the flotation tests,zeta potential experiments and adsorption capacity measurements.

Study of Chitosan -cation starch graft copolymer as Paper Strengthening Agent;

Flocculation action of cation starch for treating Kaolin suspension

Take the cation starches as the flocculant, adds PAC (polyaluminium) as the assistance flocculant, in factor under and so on consideration temperature, pH value influences, studies its effect on the printing waste water processing.
