Preparation and properties of an eco

Jan 28 2014Recently cellulose-based superabsorbent has attracted attention as a promising material in many fields because of its rich sources and outstanding properties of biodegradability and biocompatibility This study examines the potential application of a novel flax yarn waste-g-poly(acrylic acid-co-acrylamide) (FYW/PAA) superabsorbent in the absorbent core layer of sanitary napkins

What Is Coal Preparation?

What Is Coal Preparation? • Coal preparation is the removal of undesirable material from the Run-of-Mine (ROM) coal by employing separation processes which are able to differentiate between the physical and surface properties of the coal and the impurities Through coal preparation a

FURTHER STUDIES ON PREPARATION AND PROPERTIES OF

Phagocytin and histone differ significantly in the following regards: (a) the bactericidal action of histone is rapidly lost on peptic digestion while that of phagocytin is but little affected (b) the lethal effect of phagocytin on coliform bacteria is much more resistant than that of histone to antagonism by spermine or by increasing ionic strength of the medium (c) phagocytin can be

Properties Of Sulphur Dyes

Sulphur dyes are one of the most used dyes for producing bright black and brown shade on cellulosic fiber products The chemistry of sulphur dyes dyeing is near similar to vat dyes dyeing In both case final color is developed by the oxidation process Although reactive dyes azoic color is available but sulphur dyes is preferable for black shade production

Study on the Preparation and Properties of Talcum

In this study a method for the preparation of porous ceramic membrane supports is proposed Low-cost fly ash from power plants is the main material of the membrane supports and talcum is the additive The fabrication process of the ceramic membrane supports is described in detail

Study on the Static and Dynamic Fracturing Properties of

A split Hopkinson pressure bar (SHPB) system was first used to perform the cyclic impact loading tests on notched semicircular bend (NSCB) marble specimens Then static and dynamic three-point bending tests were conducted on these dynamically damaged specimens respectively In the cyclic impact loading tests the dynamic elastic modulus decreases gradually as the impact number increases but
