Description
Дл целого р да изделий необходимо устанавливать степень гладкости, ворсистости, волокнистости, степень начеса, степень грубости отделки и другие свойства поверхности, т. е. в общем ее относительную шероховатость .For a whole range of products, it is necessary to establish the degree of smoothness, hairiness, fiber, the degree of pile, the degree of roughness of the finish and other surface properties, i.e. in general, its relative roughness.
Дл этой цели примен етс небольшое количество приборов, измер ющих шероховатость путем определени трени о поверхность твердого тела. Недостатком таких приборов вл етс то, что при этом испытуема поверхность измен етс воздействием на нее измер ющего прибора.For this purpose, a small number of devices that measure the roughness by determining the friction on the surface of a solid body are used. The disadvantage of such devices is that in this case the test surface is changed by the influence of the measuring device on it.
В противоположность этому предлагаемый способ определени шероховатости тканей, бумаги, кожи и тому подобных материалов состоит в том, что на испытуемую поверхность касательно к его поверхности направл ют струю газа или жидкости и по силовому действию на образец определ ют величину относительной шероховатости .In contrast, the proposed method for determining the roughness of fabrics, paper, leather and similar materials consists in directing a jet of gas or liquid against the surface of the test surface to the surface being tested and determining the value of the relative roughness on the sample.
Примен емый дл этого, согласно изобретению, прибор имеет форму крутильных весов, на цилиндре которых укрепл етс испытуемый образец, а самый цилиндр подвешиваетс на нити , угол закручивани которой подThe device used for this, according to the invention, has the form of torsional weights, on the cylinder of which the sample under test is fixed, and the cylinder itself is suspended on a thread, the twist angle of which is under
вли нием струи газа или жидкости дает меру относительной шероховатости образца.by a jet of gas or liquid, gives a measure of the relative roughness of the sample.
На чертеже представлена примерна форма выполнени прибора, согласно изобретению, с применением воздушной струи, причем фиг. 1 показывает вид его спереди, а фиг. 2 - вид в плане . В верхней точке стойки 1 укрепл етс головка 2, несуща стальную проволоку или бифил р .3. На конце проволоки 3 подвешен цилиндр 4, так что ось цилиндра вертикальна. На окружиости Цилиндра закрепл етс лента испытуемого материала и на нее направл етс почти по касательной равномерна воздушна стру из наконечинка 5. Поворот барабана вследствие закручивани проволоки 5 отсчитываетс но градусам шкалы 6, укрепленной на крышке барабана, и по неподвижному указателю 7.The drawing shows an exemplary embodiment of an apparatus according to the invention using an air jet, with FIG. 1 shows a front view thereof, and FIG. 2 is a plan view. At the top of the post 1, the head 2 is reinforced, carrying steel wire or bifil p. 3. At the end of the wire 3 is suspended cylinder 4, so that the axis of the cylinder is vertical. On the circumference of the Cylinder, a tape of the test material is fixed and an almost equal air jet of tip 5 is directed to it almost tangentially. The rotation of the drum due to the twisting of the wire 5 is measured according to the degrees of the scale 6 fixed on the drum cover and by the fixed pointer 7.
Манометр .9 служит дл измерени .чавлени воздуха, Ю - ось цилиндра (нгла), //-гнеадо оси.A pressure gauge .9 is used to measure air pressure, Yu is the axis of the cylinder (nla), // is the gneado axis.
Пользование прибором состоит в следуюи1,ем. После надевани на цилиндр испытуемого материала отсчитываетс нуль прибора, затем пускаетс равномерна стру воздуха и отсчитываетс угол поворота барабана.The use of the device is as follows1. After putting the test material on the cylinder, the instrument zero is counted, then a uniform stream of air is blown out and the angle of rotation of the drum is counted.
