How to determine the viscosity of epoxy floor coating

Epoxy resin floor has been mature, and used in many places, such as parking lots, factory workshop, etc. However, after completion of construction, attention should be paid to monitoring the viscosity of epoxy floor coating, to guarantee the quality of epoxy floor after completion and use of time. However, it is worth noting that must pay attention to the following points when measuring, otherwise it is difficult to operate. ( 1) The identified specified temperature should be between 21 to 25 degrees. Because temperature is too high, measured the viscosity of the relatively low, the temperature is too low, relatively high viscosity, not standard. ( 2) Cleaning coating cup after each test, choose the measured coating with the corresponding solvent, prevent test hole plug. ( 3) With finger or tools plugged holes of the discharge spout and into 100 ml of paint. Using a glass rod will bubble and redundant sample in a groove, in order to prevent the below or above the standard sample. ( 4) Fast moving fingers, at the same time start the stopwatch. When the sample flow interruption, and immediately stop the stopwatch timing. Experience of viscosity of epoxy floor coating product testing method is stirring coating were observed with a stick. Free normal coating should be continuous, if there is any disruption and contraction, this shows that the coating is relatively thick. Usually, stem coating and coating of barrels will continuous flow in a short time, is 30 - connection distance 50 cm, that is, close to scrub. Less than 30 cm said coating viscosity is too small, that is, the coating is too thin. More than 50 cm said viscosity is too high, the coating is too thick. This kind of viscosity restricted by structural requirements, and used in practice, instead of using viscometer, called viscosity. By measuring the viscosity, coating can be observed in the store after a period of time of polymerization degree, and can according to the requirements of the different construction with the appropriate thinner, adjust viscosity, brush, trowel and batch in order to achieve required for blade coating construction of different viscosity index. This step in the process of construction, therefore, are indispensable. In the process of construction, must pay attention to whether workers to cut corners.
