Viscosimeter – kennis van viscositeit

Wanneer de vloeistof stroomt, er is relatieve beweging tussen aangrenzende vloeistoflagen, zodat de wrijvingsweerstand tussen de twee vloeistoflagen wordt gegenereerd, die viskeuze kracht wordt genoemd. Viscositeit wordt gebruikt om de viscositeit van fysieke gegevens te meten. De grootte wordt bepaald door het soort stof, temperatuur-, concentratie en andere factoren. Viscositeit is over het algemeen een afkorting voor dynamische viscositeit;, die wordt gemeten in Pa·s (vader·s) of mPa·s (MPa ·s).Viscositeit is onderverdeeld in dynamische viscositeit:, kinematische viscositeit:, relatieve viscositeit:, de [...]

De classificatie en toepassing van coater:

Eerst, borstel type coater Borstelcoater is een oude coatingapparatuur, voor het eerst gebruikt in de jaren 1850 om gecoat behang te maken met Chinese kleiverf. Er zijn drie verschillende soorten borstelcoaters:: ronde borstel coater, deken roller coater en deken sleeve coater.Figuur: 1 toont een vroeg gebruik van een borstelcoatingkop. Twee, luchtmes coating machine De komst van de luchtmescoater in de jaren dertig markeerde de geboorte van de moderne papiercoatingindustrie. De luchtmescoater moet de [...]

Het concept van viscositeit en het gebruik van viscosimeters

The concept of viscosity and the use of viscometersThe concept of viscosityYou often hear the word viscosity, but what is viscosity really? Viscositeit, “Viscosity.” Also known as Viscosity.Two plates with an area of 1m2 are immersed in the liquid, and the distance between the two plates is 1 meter. If the shear stress of 1N is added, so that the relative rate between the two plates is 1m/s, the viscosity of the liquid is 1 pa.s.The flowing liquid is regarded [...]

Wat zijn de kenmerken van de lijmtester??

Tackiness (instantaneous adhesion) of various PASTE and adhesive tape is tested by the adhesive tester. In the past, the difference of human factors leads to a large data error.The adhesive force tester is used to press the test probe under specific conditions (entry speed, druk, pressure time, detachment speed) to the object to be measured and test its adhesive force in the detachment process.The test data can be processed by computer. Characteristics of adhesive force testerThe control mode of the [...]

De berekeningsformule en het principe van glansmeter worden geïntroduceerd

Glossometer is a kind of instrument for measuring the gloss of solid surface by using the principle of reflection. It is used for measuring the gloss of ceramic, verf, inkt, plastic, marmeren, aluminium, hardware and other materials. *: glossiness is a physical quantity that evaluates the ability of a material surface to reflect light under a set of geometrical conditions, with reflective properties of direction selection.We usually say the gloss refers to the “mirror to the gloss”, so glossometer is [...]

Uitleg testprincipe en testmethode schrobtester

We all know that coated or uncoated surfaces need to be tested for scrub resistance with a brush, sponge, dishcloth, sandpaper, or other means. Scrub resistance tester is a special test instrument for such tests, it can use the way of wet scrubbing by adding friction agent or cleaning agent for friction resistance test. It is usually used in the scrubbing test of interior wall paint, floor tile, shower room and furniture surface. Principle and main structure of scrubbing tester 1, [...]

Effect van pigmentdispersie op coatingeigenschappen

This is a measure of the characteristics of the film, the higher the gloss, the stronger the reflection. For coating luster, particles can not be greater than 5 micron, 3 microns.Ink can not exceed 1 micron.Large particles in coatings are either inefficiently dispersed, flocculate, or stimulate crystallization during preparation.Polymer dispersants also reduce the formation of large particles due to flocculation and improve gloss. transparent This is a property of the film, the higher the transparency, the easier it is to see the [...]

Toepassing van intelligente droogtijdrecorder in de coatingindustrie

Application of Intelligent Drying Time Recorder in Coating Industry The intelligent drying time recorder is used to measure the drying time of wet film such as paint, ink and glue.The drying and curing of wet film is a slow and continuous process. In order to observe each stage of drying conveniently, an intelligent drying time recorder with certain control conditions is needed to measure.The intelligent drying time recorder uses a needle to cross the coating at a constant speed and [...]
