GB/T 21990-2008 《Polyvinyl chloride (PVC) pastes - Determination of fineness of grind》 Related products
This standard specifies a method for the determination of coarse particle size in polyvinyl chloride (PVC) (PVC) pastes using a Grindometer. For fineness testing of PVC pastes, the coarse particle size in the paste is assessed by placing the PVC paste on a tester and observing the scratches that appear by moving the drawdown blade. The standard defines "paste" as a uniform dispersion system of Resin in organic liquids, providing a technical basis for accurately determining the fineness of PVC paste, ensuring that the particle size in production and quality control meets the specification requirements.
