Method to improve water-repellent properties of felt materials consists in treatment of felt material in suspension alcohol-nanopowder hydrophobic silicon dioxide of Wacker HDK N20 grade (Germany) under the effect of acoustic cavitation in ultrasonic bath. Ethyl alcohol is used which is a low-...

A machine known as a cross-lapper or a vlamir then combines multiple webs together to make a roll, and four of these rolls are layered on top of each other to make a batt. To harden these batts of felted material, felt manufacturers expose the batts to heat and moisture, and then the...
material occurred scantily in the boulders imported from Burma. Since it was scarce and beautiful, it came to be used for personal ornaments in the form of solid rings, buckles, carved pendants, earrings, buttons, necklaces and other articles. It is this color of jadeite that is most highly...
In our contribution we study the long-term durability of two different graphite felt materials serving as negative electrode in vanadium redox flow battery. Both electrodes differ in the precursor material and the way of activation which causes significant differences in relevant properties such as ...
not only does opal grind away very rapidly, but matrix may cause serious undercutting. Sanding is best accomplished with a worn sander or a very fine sanding cloth. For polishing cabochons, use a felt wheel with tin oxide or cerium oxide; either of these agents on a lucite or tin lap is...

aOn the other hand, the solid particles in the crushing process, as the size decreases, the specific surface area increases and crystal structure changes, the physical and chemical properties of material is also changing. 另一方面,坚实微粒在击碎的过程,比如大小减退,比表面区域增量和晶体结构中改变,物...
For example, the fine filter sheet material preferably consists of a filament nonwoven which has been consolidated with fibrous or pulverulent thermal or adhesive binders, whereas the depth filter sheet material consists of a feltlike nonwoven or a needled filament nonwoven. It has now been ...
