Application of sodium hexametaphosphate in ceramic industry
1. Sodium hexametaphosphate’s role in ceramic glaze
Sodium hexametaphosphate(SHMP) can be used as an additive to control glazed flow degeneration. Add a certain amount of SHMP to the glaze, which can increase the fine viscosity and viscosity of the glaze and make the glazed liquidity more stable. At the same time, Sodium Hexametaphosphate can also improve the adhesion and hardness of the glaze, make the glaze more bright and uniform, and at the same time improve the wearing resistance of the glaze.
2. Sodium hexametaphosphate’s role in ceramic porcelain mud
Sodium hexametaphosphate can be used as porcelain mud plastic additives. In the porcelain mud formula, add SHMP to the porcelain mud formula, which can improve the plasticity and plasticity of porcelain mud. At the same time, Sodium Hexametaphosphate can also control the flow performance of porcelain mud, making porcelain mud more easily formed. After molding, Sodium Hexametaphosphat can also slowly release phosphate ions to promote the sintering of porcelain mud, making the ceramic finished product more stable and strong.
The price advantage of inorganic water-reducing agents and water-reducing effects in certain mud can also be met. Therefore, in the production of many ceramic factories, inorganic water-reducing agents are often used. Among them, Sodium Hexametaphosphate, Water Glass, and Sodium Salone Silicine are often used. The water reduction effect of SHMP is better among several water-reducing agents.
When the polymer water reduction agent is mixed with the inorganic water reduction agent, the factors of the hyperplastic water reduction agent block are used using the dual-electromagnet layer of the inorganic water reducing agent, and the water reduction effect is better. The technicians tried to reproduce the Sodium Hexametaphosphate and water glass. In the experiment, using a large floor tile plant blank, the amount of water was 34% of the blank. If only water glass and sodium sodium sodium silicate are used, the flow time of the mud is 180 seconds, which is almost impossible to flow, and the tactile is extremely large.
After adding 0.15%of the Sodium Hexametaphosphate produced by Yucai Chemical, the mud flow time was reduced to 60 seconds, and the mud liquidity improved significantly, indicating that the two different types of inorganic water reducing agents were complementary, and the performance was complementary. The agent is more advantageous. Although sodium inorganic phosphate has a significant effect on reducing the viscosity of mud and improving its liquidity, the suspension is poor.
When a small amount of 0.05%Sodium Hexametaphosphate is added, the flow rate of mud is more obvious, and the flow time is 45 seconds, indicating that the water reduction effect of Polycarp carboxylic acid polymer water reduction agent and traditional silicate water reduction agent is more significant. , While maintaining less amounts while maintaining the original mud flow rate and stability, greatly reducing the cost of additives. At present, it is difficult to solve the glaze of glaze ingredients to be less than 34%, and it can achieve about 31%of the easily soluble, and pressure will be lower in coal consumption and environmental protection.
When the amount of water added is 40%of the blank, the original complex solution is only used to use sodium glass and sodium silicate, and even if the amount of mud in the amount of sodium sodium sodium silicate can no longer be reduced; When a small amount of 0.04%sodium hexametaphosphate is added, the mud flow time quickly drops to 48 seconds. While not increasing the cost of additives, it can reduce the flow rate of the mud.
Therefore, Sodium Hexametaphosphate has developed from the beginning of water treatment to overcome the phenomenon of “red water” and developed to the extensive use of ceramics, refractory materials, detergent aids, and other industries. Metal ions are combined to generate soluble complexes. The effect achieved in ceramic water reduction agents is better than other inorganic water reducing agents.
3.Sodium Hexametaphosphate’s role in ceramic decoration
SHMP is a good assistant that can combine with ceramic pigments and other substances to form high-temperature and high-luster ceramic decorative materials. In ceramic decoration, Sodium Hexametaphosphate can improve the adhesion and color of ceramic paint, making ceramic decoration more beautiful, vivid, and lasting.
In short, Sodium Hexametaphosphate plays a vital role in ceramic manufacturing. It is widely used in ceramic glaze, porcelain mud, and decoration, which can effectively improve the quality and value of ceramics. As a ceramic worker, we should deeply understand the mechanism and application method of Sodium Hexametaphosphate, constantly apply this magic assistant to practice, and continue to be new in creation to make greater contributions to the inheritance of traditional Chinese ceramic culture in Chinese traditional ceramic culture Essence
