Light industry now requires an increasing amount of resources, and maximize as much as possible and much cheap as always - human nature is unchangeable.One publication is indispensable to cover all sectors, existing to this day, and to what it is, because it will be about a fairly highly specialized material - or rather, not enough lighting in the network.Procurers of all stripes know just where to get, how much, what kind of GOST (TU), for what purpose, and "theoretical foundations" of little interest.Moreover, not many companies involved in the direct supply, here's an example - specialization: Insulating.That's about it will be discussed, with a focus on light industry.
So, Insulating (aka - pressboard) - the result of pulp and paper production is made from unbleached pulp (sometimes - with the addition of cotton fibers), it has a "nutty" color, according to GOST (eg, GOST 2824-86) is notprovides dents, inclusions of foreign bodies, fractures, etc.Why is the "electric"?This is due to its high dielectric strength (according to the norms - not less than 80% of applications), which determines its use not only in the light industry (so-called board general purpose), but also in the manufacture of elements of the main and secondary insulation of different electric devices (electricbrand "EV" -
describing the product, it should be noted that the most frequent use of Insulating different brands is in: Clothing, furniture manufacturing, at least - in other sectors, as diverse as it makes no sense to describe.Here is just a sample list of names and formats, and the use can talk endlessly.Why is it needed sewers, for example?And we are talking about such essential things that make this production as templates.Patterns (or pattern) - that are cut out for them items of clothing and other products, they require high strength and durability.After all, the quality of the data characteristic of any product so frequent use. Cardboard patterns - Insulating is the same, for example, such very different thickness (depending on the characteristics of production), more often - EVTNP stamps or the like.Here he is no requirement for electric strength, there is no need to use oil in medium and high operating temperatures are also no.Therefore, it used the brand with a focus on strength.To use this material was justified - quite a low price, and duration of use.As can be seen, this practice is entrenched over the years, and various brands of Insulating applied everywhere, sometimes it is not clear that this is the material.
