Electrical & Manufacturing

Light industry now requires more and more resources, and as much as possible and as cheap as possible, as always - human nature is unchanged. One publication is indispensable to cover all the industries that exist to this day, and to no avail, because it will be a fairly narrowly specialized material, or rather - little-lit in the network. Supporters of all stripes know only where to get it, how much, what GOST (TU), for what purposes, and "theoretical foundations" are of little interest to them. Especially not so many companies dealing with direct supplies, here is an example - specialization: electrocard. It is about him that will be discussed, with an emphasis on light industry.

So, the electrocardboard (the same as the pressboard) is the result of pulp and paper production, it is made from unbleached cellulose (sometimes with the addition of cotton fibers), has a "nutty" color, according to GOST (for example, GOST 2824-86) does not provide dents, inclusions Foreign bodies, ruptures, etc. Why "electro"? This is due to its high electrical strength (at least 80% of the declared value), which determines its use not only in light industry (so-called general-purpose cardboard), but also in the manufacture of main and secondary insulation elements of various electric units Brand "EV" - electrical insulating high-voltage ). Here is a brief description of what we are dealing with.

Describing this product, it should be noted that the most frequent use of electrical cards of different brands is found in: sewing, furniture manufacturing, less often in other industries, so diverse that there is no point in describing it. Here is just an indicative list of brands and formats, and you can talk about use indefinitely. Why do they need sewing, for example? And we are talking about such irreplaceable things, specific for this production, as a templar. Patterns (or patterns) - it is for them to cut out the elements of clothing and other products, they require high strength and durability. After all, these qualities are typical for any products of such frequent use. Cardboard for patterns is the same electrical card, for example, it is quite different in thickness (depending on the features of production), more often - EVTNP grades or the like. Here, there are no requirements for it on the electrical strength, there is no need for its use in an oil medium and high operating temperatures here, too. Therefore, marks are used with an emphasis on strength. To use this material was justified - a fairly low price, and continued use. As you can see, this practice has been fixed over the years, and the electrocard board of various brands is used everywhere, sometimes it is not even clear that this is exactly this material.
