Metal material process performance
The adaptability of metals to various processing methods is called process performance, and there are four main aspects: (1) Machining performance: Reflects the difficulty of cutting metal materials with cutting tools (such as turning, milling, planing, grinding, etc.). (2) Forgeability: Reflects the difficulty of forming metal materials during pressure processing, such as the plasticity of a material heated to a certain temperature (expressed as the degree of plastic deformation resistance), allowing the temperature range of hot pressure processing, Thermal expansion and contraction characteristics and limits of critical deformation related to microstructure and mechanical properties, fluidity of metal during thermal deformation, thermal conductivity, and the like. (3) Castability: Reflecting the difficulty of melting and casting a metal material into a casting, showing fluidity, aspiration, oxidation, melting point, uniformity, compactness, and cold shrinkage of the microstructure of the casting. Wait. (4) Solderability: Reflecting the rapid heating of the metal material in the local part, so that the bonding part is rapidly melted or semi-melted (requires pressure), so that the bonding parts are firmly bonded together to become a whole degree of difficulty, which is expressed as melting point and melting. The gettering property, oxidizing property, thermal conductivity, thermal expansion and contraction characteristics, plasticity, and the correlation with the microstructure of the joint portion and the nearby material, and the influence on the mechanical properties. Thickener & Workability Modifier To achieve certain thickening effect, fantastic workability and application easiness, thickener is always necessary to added into various kind of dry mix mortar. Quality Cellulose Ether with different viscosity ensures excellent water retention effect and achieve additional properties like antisag or antislip properties and improves open time for tile adhesive. Starch Ether is an excellent thixotropic agent which give additional application workability and suitable for many types of troweling products like plaster, render and wall putty. Organic bentonite is a kind of layer silicate, as Mineral Thickener, which is quite good for pumping aid, and suitable for the products with machinery application.
