Why can high-efficiency water reducing agent sodium tripolyphosphate promote the industrialization of ceramic production?
Reducing ceramic production costs is an important aspect in adapting to modern technological innovation and high-quality development. Sodium tripolyphosphate, a ceramic water reducing agent, has good dispersibility, suspension, and binding properties. It is a ceramic additive that integrates multiple functions and is also an ideal additive for economy, energy conservation, convenient use, and stable performance. It is widely used in many ceramic production enterprises and has obvious effects.
The use of ceramic water reducing agents in ceramic production can not only improve the fluidity of ceramic slurry, but also reduce its water content, improve the performance of ceramics, and have the effect of improving product performance and energy conservation and emission reduction.
At present, sodium tripolyphosphate is a high-performance water reducing agent in high demand in the ceramic field. Sodium tripolyphosphate mainly chelates divalent ions such as calcium and magnesium in clay mud, and through cation exchange, more sodium ions surround the clay. The replaced calcium and magnesium ions chelate with polyphosphate to form soluble complexes, supplementing the steric hindrance effect. Make the clay have higher fluidity and even dispersion in even less water.
Ceramic powder is dispersed in water and aggregates to form a slurry of particle bundles. Sodium tripolyphosphate water reducing agent is added to the slurry, where the molecules in the sodium tripolyphosphate water reducing agent can adsorb on the surface of ceramic particles in the slurry, and through adsorption, they interact to destroy the flocculation between particles, resulting in a slurry with good dispersibility and fluidity. By reducing the number of molecules in the hydration layer through sodium ions, excess adsorbed water is released, increasing the content of free water in the mud and achieving a water reduction effect.
Summarized several characteristics of sodium tripolyphosphate ceramic water reducing agent:
1. It can be widely used in the grinding process of the ceramic industry.
2. It can make the mud have good fluidity and low viscosity and meet the requirements of spray.
3. Reduce water content of slurry, improve stability, reduce energy consumption of spray drying tower, and reduce production cost.
4. It has a grinding aid effect on mud particles, shortens ball milling time, improves ball milling efficiency, and saves energy consumption.
In order to reduce the production cost of ceramics, after continuous summary and research, sodium tripolyphosphate is widely used in the process of mud making, slurry grinding, glaze making, and other processes in the ceramic industry. This way, the water content of the mud glaze is low, the fluidity is good, and there will be no backsetting. The stability is also very good, which helps to achieve industrial production of ceramics.
