Production Processing Key Points of Comb Superfine Count Yarn;

Practice of Spinning Superfine Count Yarn by WRC965 Aluminum Bushing Roller;

Controlling hairiness of superfine count yarn and advancing weaving properties;

Practice of spinning super fine yarn with aluminium inserted nontreatment tube NFR-W0358 as the front cot shows excellent performance in anti-entangling,anti-abraion,stable in rigidity,thus a choice for spinning yarn of CJ5.

This article draws the conclusion that the blowing-carding process can run stable,and it can be utilized in long-staple cotton and super fine yarn.

Introductory research of superfine sand high strength concrete/Jiujiang college of civil engineering and urban construction;

Study on dry-mixed superfine sand mortar for plastering aerated concrete;

The workability,compressive strength,compressive modulus of elasticity,apparent quality,drying shrinkage and resistance to hydraulic pressure of as-cast finish concrete mixed with machine-made sand and superfine sand instead of natural medium sand was introduced.

The causes analysis and avoiding measure of the layering of the special fine sand concrete;

On the application of the polypropylene fiber in the special fine sand concrete;

Changing the characteristic of special fine sand can reduce cement,enhance the concrete workability,increase the durability.

Application of QQ-06 Size Mixture in Superfine Yarn Sizing;

Practice of Reducing Superfine Yarn Hairiness in S432 Sizing Machine;

The production of the super fine cotton twills is introduced.

Experimental study on characteristics of hydraulic super-fine sand concrete;

The use of super-fine sand in massive underwater subsealing concrete;

The mechanica behaviors as well as the stress-strain relationship characteristics of high strength concrete made of super-fine sand are studied through experiments.

Mix-proportion design and high-lift pumping of extra fine sand concrete;

China is rich in extra fine sand, such as river sand in the Changjiang River, Yellow River and Zhujiang River, blow sand in the area of northeast China and Xinjiang.

A high-performance concrete with the caving degree of 200mm and 28-day compression strength of 80 Mpa can be made by using extra fine sand as aggregate, superfine slag as admixture with a water and glue ratio of 0.
