Viscosimètre – connaissance de la viscosité

When the fluid is flowing, there is relative movement between adjacent fluid layers, so the frictional resistance between the two fluid layers will be generated, which is called viscous force.Viscosity is used to measure the viscosity of a physical data.Its size is determined by the kind of substance, Température, concentration and other factors.Viscosity is generally short for dynamic viscosity, which is measured in Pa·s (Pennsylvanie·s) or mPa·s (MPa ·s).Viscosity is divided into dynamic viscosity, kinematic viscosity, relative viscosity, the [...]

La classification et l'application de la coucheuse

D'abord, brush type coater Brush coater is an ancient coating equipment, first used in the 1850s to produce coated wall paper using China clay paint.There are three different types of brush coaters: round brush coater, blanket roller coater and blanket sleeve coater.Figure 1 shows an early use of a brush coating head. Deux, air knife coating machine The advent of the air knife coater in the 1930s marked the birth of the modern paper coating industry.Air knife coater is to overcome the [...]

Le concept de viscosité et l'utilisation de viscosimètres

The concept of viscosity and the use of viscometersThe concept of viscosityYou often hear the word viscosity, but what is viscosity really? Viscosité, “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 [...]

Quelles sont les caractéristiques du testeur d'adhésif?

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, pression, 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 [...]

La formule de calcul et le principe du brillancemètre sont introduits

Le glossomètre est une sorte d'instrument pour mesurer la brillance d'une surface solide en utilisant le principe de la réflexion. Il est utilisé pour mesurer la brillance de la céramique, Peinture, encrer, Plastique, marbre, aluminium, quincaillerie et autres matériaux. *: la brillance est une grandeur physique qui évalue la capacité d'une surface de matériau à réfléchir la lumière dans un ensemble de conditions géométriques, with reflective properties of direction selection.We usually say the gloss refers to the “miroir à la brillance”, so glossometer is [...]

Peu de connaissance de l'instrument de scratch

The scratch resistance tester provides a way to measure the scratch resistance of single or multiple coatings under specified conditions.Permeability of paint, peinture en bobine, encre d'étain, ou des produits connexes via une aiguille hémisphère ou un outil à gratter. Description de l'apparence de l'instrument 1, composition d'instrument: par une coulée métallique revêtue, moteur d'entraînement, plaque de test supportant la pince de cadre, panneau de commande de l'instrument. 2, la balance est installée sur la pince de plaque de test, le stylet ou le stylet scratch est fixé sur le bras d'équilibrage sous un petit cadre de roulement. Écran tactile du testeur de rugosité de surface KR310 [...]

Le suivi de la température du four apporte le taux de haute qualité

Furnace temperature tracker is an excellent insulation performance to enable the test system to perform temperature mapping in harsh thermal environments.Through the heat treatment furnace with the products, the temperature of the heat treatment furnace and the products can be monitored throughout the process. The temperature data of the whole process can be obtained without the pull couple test, which will tell you how to improve the operation.Allows you to improve output and product quality, to achieve production. Furnace temperature [...]

Explication du principe de test et de la méthode de test du testeur de récurage

We all know that coated or uncoated surfaces need to be tested for scrub resistance with a brush, sponge, dishcloth, papier de verre, 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, [...]

Effet de la dispersion de pigment sur les propriétés du revêtement

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 microns, 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 [...]

Application de l'enregistreur de temps de séchage intelligent dans l'industrie du revêtement

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 [...]
