This depends not only on the materials, but also on the load on the brush and the filament-surface friction coefficient. We can calculate the acceptable number of revolutions n of the brush with a function &#8216;f&#8217; of the static and dynamic parameters and check that it is: <\/span><\/p>\n<p class=\"p1\"><span style=\"color: #001240;\">n &lt; f (s, Ft, Pm, D1, D2, P) where s = safety coefficient, which must take into account the type of load applied<\/span><span style=\"color: #001240;\">Ft = resistance of the bundle to tearing [Kg] Pm = weight of the bundle [gr] P = depth of the bundle hole [mm]<\/span><\/p>\n<p class=\"p1\"><span style=\"color: #001240;\">We are available to provide you with the necessary project data.

Power consumption varies depending on brush diameter, speed, working length and filament hardness. It is also greatly affected by the pressure exerted on the brush. <\/span><\/p>\n<p class=\"p1\"><span style=\"font-weight: 400;\">It is therefore only possible to establish the power as an average value and as a first approximation.

The brushing surface can be continuous, sectoral or spiral. The number of bundles depends directly on the number of Z teeth, so brushes with different densities are possible, according to the table. Modular rollers have the advantage that they can form brushes of different lengths and are easy to replace and transport. On the other hand, they have a certain limitation in diameters and bundle arrangement. In fact, these parameters are constrained by the characteristics of the brush body, which being obtained by moulding does not allow for all possibilities. In other words, the modular method can replace the traditional one-piece brush only for the standard dimensions shown in the table.<\/span><\/p>\n<p>[\/vc_column_text][\/vc_column_inner][vc_column_inner width=&#8221;1\/3&#8243;][vc_single_image image=&#8221;731&#8243;

In a nutshell, it can be said that 2 mm is a good compromise. The important thing is that the brush filaments work &#8216;on the tip&#8217; and not on the side.<\/span>[\/vc_toggle][vc_toggle title=&#8221;Can a bundle of filament be detached from the brush body?&#8221; custom_font_container=&#8221;tag:h3|text_align:left|color:%23001240&#8243; custom_use_theme_fonts=&#8221;yes&#8221; use_custom_heading=&#8221;true&#8221;]<span style=\"font-weight: 400;\">Depending on the materials used and the dimensions, there is a limiting tensile load that an individual bundle can withstand. <\/span><\/p>\n<p><span style=\"font-weight: 400;\">Beyond this limit, the bundle comes off, so the brush must be calculated according to use. This limit can be greatly increased by constructing &#8216;sewn&#8217; or &#8216;tied&#8217; brushes by hand, where instead of a single anchoring element, a continuous steel wire is placed.<\/span>[\/vc_toggle][vc_toggle title=&#8221;Is a punched brush or a strip cheaper?&#8221; custom_font_container=&#8221;tag:h3|text_align:left|color:%23001240&#8243; custom_use_theme_fonts=&#8221;yes&#8221; use_custom_heading=&#8221;true&#8221;]<span style=\"font-weight: 400;\">There is no single answer. Speaking of e.g. cylindrical brushes, the strip brush is generally cheaper when the dimensions are large (e.g. over one metre in length). For small dimensions, punched brushes are certainly more suitable and convenient.<\/span>[\/vc_toggle][vc_toggle title=&#8221;Is it possible for a single filament to slip out of the bundle and contaminate the product?&#8221; custom_font_container=&#8221;tag:h3|text_align:left|color:%23001240&#8243; custom_use_theme_fonts=&#8221;yes&#8221; use_custom_heading=&#8221;true&#8221;]<span style=\"font-weight: 400;\">This can only happen if the brush has a manufacturing defect, like any other type of object (e.g. a roller made of silicone flakes, one of which is defective and breaks).<\/span><\/p>\n<p><span style=\"font-weight: 400;\">When it is important that no contamination occurs, synthetic (not natural) fibres with a diameter greater than or equal to 0.15 mm should be used.<\/span>[\/vc_toggle][vc_toggle title=&#8221;What softness or hardness of brush can I achieve?&#8221; custom_font_container=&#8221;tag:h3|text_align:left|color:%23001240&#8243; custom_use_theme_fonts=&#8221;yes&#8221; use_custom_heading=&#8221;true&#8221;]<span style=\"font-weight: 400;\">Practically all degrees of hardness are possible, from very soft to very hard. In fact, hardness is a combination of the filament diameter, its free length and the density of the bundles.<\/span>[\/vc_toggle][vc_toggle title=&#8221;Is it possible to have a certified &#8216;food grade&#8217; brush?&#8221; custom_font_container=&#8221;tag:h3|text_align:left|color:%23001240&#8243; custom_use_theme_fonts=&#8221;yes&#8221; use_custom_heading=&#8221;true&#8221;]<span style=\"font-weight: 400;\">Of course, we can provide FDA or FOOD GRADE certification and filament traceability.<\/span>[\/vc_toggle][vc_toggle title=&#8221;Is it possible to have an ATEX-certified brush?&#8221; custom_font_container=&#8221;tag:h3|text_align:left|color:%23001240&#8243; custom_use_theme_fonts=&#8221;yes&#8221; use_custom_heading=&#8221;true&#8221;]<span style=\"font-weight: 400;\">Unfortunately not, as it is the machine + brush assembly that needs to be ATEX certified, not the brush alone.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">However, it is possible to supply the materials that the certifier requires, e.g. conductive bases, conductive filaments, etc.<\/span>[\/vc_toggle][vc_toggle title=&#8221;Is it possible to &#8216;regenerate&#8217; a worn-out brush?&#8221; custom_font_container=&#8221;tag:h3|text_align:left|color:%23001240&#8243; custom_use_theme_fonts=&#8221;yes&#8221; use_custom_heading=&#8221;true&#8221;]<span style=\"font-weight: 400;\">Generally speaking, it is possible, but one has to assess whether it is cost-effective, which is not always the case. In addition, in the case of a punched brush, it is inadvisable to regenerate the brush more than twice, so as not to reduce the tightness of the bundles.<\/span>[\/vc_toggle][\/vc_column][\/vc_row][\/vc_section]<\/p>\n<\/section>","protected":false},"excerpt":{"rendered":"<p><b>Punched roller brushes<\/b> are the most commonly used types in industry, where they can be found in a large number of manufacturing processes.
