Emulsion Solid content determination
Solid content of emulsion is an important indicator to evaluate its performance. It directly affects the performance and application effect of emulsion, such as viscosity, Stability and Spreader. By understanding Solid content, you can optimize the production process, improve raw material utilization and reduce costs.
Solid content determination method
Solid content refers to the percentage or mass fraction of solid matter contained in a liquid. It is an indicator that describes the concentration or content of solid matter in a liquid. Solid content is often used to describe the content of solid matter in various solutions, suspensions, emulsions, colloids and other liquid systems.
Performance Testing Subjects and Testing Instruments of Waterborne Epoxy Resin Coatings
The coating performance test of waterborne epoxy resin coatings can currently be tested from several aspects such as coating appearance, solid content, viscosity, fineness, curing time, adhesion, impact resistance, acid resistance, alkali resistance and salt resistance. Relevant test methods can refer to the current standards of coatings.
Detection of Phenyl-acrylic Waterborne Varnish Emulsion and Film-forming Properties
The solid content, viscosity, pH, gloss, water resistance and wear resistance of phenyl-acrylic water-based varnish emulsion were tested.
Performance Test and Characterization of Polyacrylate Mixed Suspension
Performance test and characterization of polyacrylate mixed suspension: solid content test, stability test, coating film thickness test, gloss test, light transmittance test, SEM characterization, coating film rubbing resistance test and water resistance test, etc.
How to measure solid content?
The solid content is measured by GB/T 1725. After drying the clean surface dish, weigh the mass m0, accurately weigh about 1g of the sample in the surface dish, the total mass m1, and place it in the oven at 150 ± 2 ° C. After drying for 2h, the total mass m2, and carry out 3 parallel experiments at the same time to ensure that the error before and after does not exceed 0.01g.
Coating routine performance inspection items
The routine performance inspection items of coatings include fineness, viscosity, solid content, density, dryness, sagging, color, etc.
Adhesive coating prepared by RDS wire rod film
Adhesive coating was prepared with RDS wire rod film device, the experimental Adhesive was diluted with ethyl acetate to 10 mass% Solid content, and then a small amount of wire rod with RSD4 ink rod (coating Film thickness about 7 μm) was evenly coated on 50 μm BOPP film, a part of it evaporated at room temperature, and a part was dried at 120 ° C for 1h to obtain Adhesive coating. The coating performance can be detected.
