유체가 흐를 때, 인접한 유체층 사이에 상대적인 움직임이 있습니다., 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, 온도, concentration and other factors.Viscosity is generally short for dynamic viscosity, which is measured in Pa·에스 (아빠·에스) or mPa·에스 (MPa ·에스).Viscosity is divided into dynamic viscosity, 동점도, relative viscosity, the [...]
첫 번째, brush type coater Brush coater is an ancient coating equipment, 중국 점토 페인트를 사용하여 코팅된 벽지를 생산하기 위해 1850년대에 처음 사용되었습니다. 브러시 코터에는 세 가지 유형이 있습니다.: 라운드 브러시 코터, 담요 롤러 코터 및 담요 슬리브 코터.그림 1 브러시 코팅 헤드의 초기 사용을 보여줍니다.. 둘, 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 [...]
The concept of viscosity and the use of viscometersThe concept of viscosityYou often hear the word viscosity, but what is viscosity really? 점도, “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 [...]
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, 압력, 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 [...]
Glossometer는 반사 원리를 이용하여 고체 표면의 광택을 측정하는 도구입니다.. 세라믹의 광택을 측정하는데 사용됩니다., 페인트, 잉크, 플라스틱, 대리석, 알류미늄, 하드웨어 및 기타 재료. *: 광택은 일련의 기하학적 조건에서 빛을 반사하는 재료 표면의 능력을 평가하는 물리량입니다., with reflective properties of direction selection.We usually say the gloss refers to the “광택에 비추다”, so glossometer is [...]
The scratch resistance tester provides a way to measure the scratch resistance of single or multiple coatings under specified conditions.Permeability of paint, coil paint, tin ink, or related products through a hemisphere needle or scratch tool. Instrument Appearance Description 1, instrument composition: by a coated metal casting, driving motor, test plate supporting frame clamp, instrument control panel. 2, the balance is installed on the test plate clamp, stylus or scratch stylus is fixed on the balance arm under a small bearing frame. 그만큼 [...]
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 [...]
코팅되거나 코팅되지 않은 표면은 브러시로 내스크럽성을 테스트해야 한다는 것을 우리 모두 알고 있습니다., 스펀지, 행주, 사포, 또는 다른 수단. Scrub resistance tester는 이러한 테스트를 위한 특별한 테스트 장비입니다., 마찰 저항 시험을 위해 마찰제 또는 세척제를 첨가하여 습식 스크러빙 방식을 사용할 수 있습니다.. 그것은 일반적으로 실내 벽 페인트의 스크러빙 테스트에 사용됩니다., 바닥 타일, 샤워실 및 가구 표면. 스크러빙 테스터의 원리 및 주요 구조 1, [...]
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 미크론, 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 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 [...]
