Business and science
In the world of building technologies it is difficultl to find something in order to make a surprise. Especially now, when the science is closely connected with manufacture, considerably lifting quality of building.
And here a concrete example.
The grid twisted, twisted in special way in the form of six-coal cells known as Mane weaving, in general, is not new. It was used earlier, for example, in landscape works at strengthening of a ground and in the form of a protection. The invention has come from the unexpected side. Scientists have paid attention to natural perfection of beer honeycombs having the form of a hexagon and have suggested to use a twisted grid in plaster works.
The result has surpassed all expectations. It is difficult to argue that the six-coal form of a cell "holds" a solution is better, than rectangular; strengthens effect and special joints, used at grid manufacture. Unlike a woven grid which is now used in plaster works, the solution completely lays down on a working surface, not jumping aside from a grid. The grid does not hold a solution but only reinforces it, not supposing cracks.
Plasterers have estimated that the grid accepts any form, any bends of a surface. They can work easier, so, more effectively. Besides, the solution is spent economically, and it is important. Thus the twisted grid is cheaper than woven, and even than the welded. A twisted grid at temperature drops in regular intervals
It works both on expansion, and on compression. The cell form distributes horizontal pressure from one point on a surface of all grid. This grid is a subject to influence induced by electrons considerably to a lesser degree (currents Foucault), than welded grids, at the expense of absence of welded connections that reduces susceptibility to electrocorrosion.
