Properties of casein grafted acrylonitrile fibers with different casein feed ratioes

Thus the adsorption effect and conditions of the heavy metallic ions such as Cu~(2+), Ni~(2+), and Zn~(2+) by the modified acrylic fiber at static state were studied.

This paper discussed the technique of production used for wound dressing,which is made up of fine polypropylene knitted fabrics on the outside,and needle punched nonwoven fabrics of high water absorbing modified acrylic fiber on the inside.

The results show that the grafted casein fibers were sensitive to temperature.

It is found out that the improvement effect of the anti-seepage behavior of the concrete admixed with modified polypropylene fiber is related to the fiber amount admixed,within certain scope,the more the amount,the better the effect but meanwhile,the concrete slump reduces accordingly.

Cope with the application technical problem of mixing with modified polypropylene fiber and steel fiber in concrete,incorporate mixture s crack resistance and fundamental characteristic s reinforcement,and compare with steel-polypropylene fiber concrete and common concrete through contrast test.

Added the modified polypropylene fiber (is short for modified PPF) to the concrete, the modified PPF can prevent drying and shrinkage cracks on construction.
