Vitreous and porcelain enamels--Determination of fluidity behaviour--Fusion flow test ICS 25.220.50 Y26 National Standards of People's Republic of China Enamel products and enamel Fluidity test melt flow test (ISO 4534.2010, IDT) Published on.2019-10-18 2020-05-01 implementation State market supervision and administration China National Standardization Administration issued ForewordThis standard was drafted in accordance with the rules given in GB/T 1.1-2009. This standard uses the translation method equivalent to ISO 4534.2010 "Test Melt Flow Test for Enamel Products and Enamel Fluidity". This standard is proposed and managed by the China Light Industry Association. This standard was drafted. Donghua University, National Eyeglass Glass Enamel Product Quality Supervision and Inspection Center, Shanghai Glasses Glass Enamel Products Quality supervision and inspection station. The main drafters of this standard. Dai Qi, Xu Xiaojian, Wu Jiaxu, Wang Helan, Zhang Guofan, Sun Huanbao, Gong Miao, Xu Zhangqian. Enamel products and enamel Fluidity test melt flow test Caution - If sufficient safety measures are not taken, the substances and procedures required by this standard may be harmful to health. This standard Does not involve any health hazards, safety or environmental issues associated with this standard. Use of this standard should be suitable for health, safety and environmental access Observe the precautions and comply with the relevant regulations of China and the world. Compliance with this standard cannot be used as a legal basis for exemption.1 ScopeThis standard specifies a method for testing the enamel fluidity of enamel during firing. This method is a relative method of fluidity testing (Comparative method), not an absolute method.2 PrincipleAccording to the conditions of sample preparation, it can be divided into dry preparation or wet preparation. Cylindrical sample with a certain weight can be made of enamel powder, dry The dried glaze or the reference sample agreed by both parties is pressed. The sample was placed on an unglazed ceramic plate in a horizontal position in an electric furnace and melted to a hemispherical shape at a predetermined temperature. Then, tilt An glazed ceramic plate to allow molten enamel to flow at a certain angle for a predetermined period of time. The flow length coefficient F1 and the flow width coefficient Fb are calculated based on the flow length and flow width of the sample.3 Materials and equipment3.1 Reference sample. It is agreed by both parties to the contract that it has similar melt flow properties to the tested enamel. 3.2 Ball mill. 3.3 Drying equipment. such as oven, electric hot plate or sand bath. 3.4 Research and development. 3.5 捣 hammer. 3.6 Balance. The accuracy is 0.01g. 3.7 Press. It can produce a pressure of at least 5N/mm2 with a cylindrical mold with an inner diameter of 8mm~10mm. Every experiment, A mold of the same specification should be used. 3.8 Flow plate. It consists of a smooth, uniform, non-glazed ceramic plate made of at least 1100 ° C. It has a side length of about 75 mm and a thickness of 5mm~6mm, the water absorption rate is ≤25% under atmospheric pressure. It can also be cut from a larger ceramic plate (see A.1). 3.9 Tilting frame. It is used to place the flow board horizontally in the experimental electric furnace. The inclination angle of the board is between 30° and 90°, as shown in Figure 1 and Figure 2. Note. For specimens with very high viscosity, increase the angle of inclination. ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 38092-2019_English be delivered?Answer: Upon your order, we will start to translate GB/T 38092-2019_English as soon as possible, and keep you informed of the progress.
