Problems solved by technology

Although these water-reducing agents have a significant water-reducing effect, they have a single function and are only suitable for spray-dried mud. For mud formed by plastic methods, it may have adverse effects on the filtration, forming and drying properties of mud. , therefore, limit the wide application of these water reducing agents in the ceramic industry billet preparation process

Embodiment 1

[0021] Example 1 Multifunctional ceramic composite additive and its application in ceramic dry forming blanks: The ceramic dry forming blanks are spray-dried from the ball-milled slurry to form spherical powder particles with good fluidity and filling properties. The plasticity of the mud is not highly required.

[0022] The multifunctional ceramic composite additive suitable for ceramic dry forming consists of the following raw materials in parts by mass:

[0023] 5 parts of layered crystalline sodium disilicate,

[0024] Modified 4A zeolite 5 parts,

[0025] 40 parts of sodium metasilicate,

[0026] Sodium tripolyphosphate 6 parts,

[0027] Sodium hexametaphosphate 10 parts,

[0028] 2 parts polycarboxylate,

[0029] Sodium lignosulfonate 5 parts,

[0030] Sodium humate 10 parts.

[0031] After the above-mentioned raw materials are accurately weighed, they are fully stirred in a mixer to obtain a powdery mixture with no agglomerated particles and uniform color, which ...

Embodiment 2

[0034] Embodiment 2 multi-functional ceramic composite additive and its application in ceramic plastic method forming blank: the ceramic plastic method forming blank is the mud after ball milling after press filtration (squeezing mud) and vacuum mud refining, according to different products and formulas , Spinning or trimming is carried out under the condition of water content of 18%-23%. The plastic forming method has higher requirements on the pressure filter performance of the mud and the plasticity of the mud.

Embodiment 3

[0047] Embodiment 3: multi-functional ceramic composite additive and its application in the mud used in ceramic grouting method: The mud used in ceramics grouting method is that the mud after the ball mill is stale and vacuum degassed and injected into the plaster mold by centrifugation or pressure Or in the resin mold, the water in the mud is absorbed by the pores in the mold and formed. The mud used for grouting molding has high requirements on its water content and filtration performance. When the water content is high, the mold needs to absorb more water, and poor filtration will prolong the grouting cycle and affect the output and life of the mold.

[0048] The multifunctional ceramic composite additive suitable for ceramic slip casting method consists of the following raw materials in parts by mass:

[0049] 15 parts of layered crystalline sodium disilicate,

[0050] Modified 4A zeolite 10 parts,

[0051] 20 parts of sodium metasilicate,

[0052] Sodium tripolyphospha...

Abstract

The invention discloses a multifunctional ceramic composite additive, which is prepared by mixing layered crystalline sodium disilicate, modified 4A zeolite, sodium metasilicate, sodiumtripolyphosphate, sodium hexametaphosphate, polycarboxylate, sodium lignin sulfonate and sodium humate, has various functions of assisted grinding, slushing, plastifying and the like, and is suitable for preparation of ceramic mud added in various forming methods. The additive can lower the moisture content of the mud to 28-32%, improves the ball milling efficiency to a large extend, shortens the ball milling time by 20-30%, reduces the power consumption for raw material grinding by more than 40%, obviously enhances batch plasticity, increases the dried green strength of the product by 10-15%, and has the obvious functions of increasing production, saving energy and reducing consumption.

Description

technical field [0001] The invention relates to a material preparation technology, and further refers to a preparation and application technology of a ceramic composite additive having multiple functions such as grinding aid, water reduction, and plasticization. Background technique [0002] Traditional ceramics are mainly made of clay, quartz, feldspar and other raw materials. After long-term ball milling, they are molded by plastic method or dry method, and then fired at high temperature. The preparation technology and process conditions of ceramic mud are very important to obtain high-quality and low-energy-consuming mud. In order to prepare mud with high solid content, good fluidity and stability, cationic water reducing agents, such as water glass, sodium tripolyphosphate, sodium humate, etc., are usually added to the mud. Although these water-reducing agents have a significant water-reducing effect, they have a single function and are only suitable for spray-dried mud...
