Problems solved by technology

[0003] The plastic hollow rinse ball involved in the Chinese patent ZL89108618 is not easy to wear, but the preparation cost is high, the process is complicated, and the color effect of the cloth after grinding and washing is poor;
[0004] Chinese patent ZL92100090.1 relates to a synthetic zeolite rinse ball, which uses cement hydration to bond zeolite particles, zeolite powder and expanded perlite. It needs to be soaked with potassium permanganate or oxalic acid before use, which brings many troubles to use and environmental protection;
[0005] Chinese patent ZL92104698.7 relates to a synthetic washing ball, the preparation method is to mix zeolite slag or zeolite powder with quicklime, cement, gypsum and aluminum powder The air agent and the acacia powder degreasing agent are placed together in a high-speed mixer, stirred and mixed to generate gas, and then sent to the autoclave for constant temperature maintenance. This method has complex processes and high costs;
The disadvantage is that the texture is soft and the cost is high

Embodiment 1

[0021] (1) Ingredients: uniformly mix 85 wt% of expanded perlite particles with a particle size of 0.5mm and 15 wt% of glass powder to form expanded perlite ceramic powder.

[0022] (2) Molding: adopt water-added dry pressing molding, add the water of 5wt% of expanded perlite ceramic powder amount, after uniform mixing, molding is made into the water-washed ball green body;

[0023] (3) Firing: The dried body is fired at 850°C for 3 hours to obtain expanded perlite ceramic water-washed balls.

[0024] The purity of the batching raw materials used in the experiment is industrial pure.

[0025] After inspection, the technical indicators of the prepared product are: average strength 15Mpa., average pore diameter about 0.4mm, body density 0.4g / cm 3 .

Embodiment 2

[0027] (1) Ingredients: first mix 87wt% of glass powder, 3wt% of sodium fluorosilicate, 4wt% of borax, 3wt% of zirconium silicate with a particle size of 0.2 μm and 3wt% of light calcium carbonate. The ratio of material to ball is 1: The ratio of 1 is put into a ball mill, mixed and ground for 1 hour to form foam glass powder, and then 65wt% of expanded perlite particles with a particle size of 1mm and 35wt% of foam glass powder are evenly mixed to form expanded perlite ceramic powder;

[0028] (2) Forming: the foam glass powder is added with 15wt% water of the foam glass powder, mixed in a mud mill to form plastic mud and extruded mud sticks, and then cut into columnar water-washed ball blanks;

[0029] (3) Firing: The dried green body is fired at 750°C for 1 hour to obtain expanded perlite ceramic water-washed balls.

[0030] The purity of the batching raw materials used in the experiment is industrial pure.

[0031] After inspection, the technical indicators of the prepare...

Embodiment 3

[0033] (1) Ingredients: first mix 75wt% of glass powder, 10wt% of sodium fluorosilicate, 5wt% of borax, 5wt% of nucleating agent and 5wt% of foaming agent, and load it with a ratio of material: ball ratio of 1:1 In the ball mill, mix and grind for 2 hours to form foam glass powder, wherein the nucleating agent adopts a mixture of vanadium pentoxide and zirconia with a particle size of 0.3 μm, and its weight ratio is 1: 1, and the blowing agent adopts a mixture of carbon powder and magnesium carbonate. The weight ratio is 1: 3, and then the expanded perlite particle 40wt% of 3mm is mixed with foam glass powder 60wt% to form expanded perlite ceramic powder;

[0034] (2) Molding: the expanded perlite ceramic powder plus 15wt% water of the expanded perlite ceramic powder is mixed in a mud mill to form plastic mud and extruded mud sticks, and the expanded perlite ceramics of different diameters are made by hand and washed with water Ball body;

[0035] (3) Firing: The dried green ...

Abstract

The present invention provides a method which is used for preparing an expanded perlite ceramic flush sphere and comprises the steps of batching, molding and baking, and the method has the following characters: 40-97wt% expanded perlite with granularity 0.1 to 3mm and 3-60wt% bonding agent are mixed with the proportion to prepare the uniform expanded perlite ceramic powder, then the expanded perlite ceramic powder is prepared to flush sphere base substrate, the base substrate is baked for 1-6 hours at the temperature 500 to 950 DEG C when it is dried, and the expanded perlite ceramic rinshing sphere is prepared. The invention produces the ceramic flush sphere by combining the powdered glass or foam glass with the expanded perlite, the density is increased along with the amount increasing of the binding agent, by controlling the adding amount of the binding agent, temperature and baking time to control the density and strength of the product, the purpose of increasing the wear-resisting property of product is obtained, the inside and outside arrangement of pore diameter of the prepared flush sphere is uniform, the strength and wear-resisting property is 10 to 20 times of the common ceramic flush sphere, the technique is simple and the producing cost is low, the cubic effect of the decorative pattern which is washed by the expanded perlite ceramic flush sphere is excellent and the appearance is beautiful.

Description

Technical field [0001] The invention relates to a preparation method of expanded perlite ceramic washing balls, belonging to the technical field of porous ceramic preparation technology. Background technique [0002] Washing balls are mainly used in the garment industry for grinding, washing and rinsing of materials and garments, such as denim fabrics, washed fabrics and their garments. At present, natural zeolite is mainly used, but because natural zeolite is soft and consumes a lot, it needs to be stopped at any time to replenish during use, which seriously affects the efficacy, and the zeolite waste residue is difficult to recycle, which is easy to cause environmental pollution. In response to the above problems, there have been technical reports on washing balls made of other materials, such as: [0003] The plastic hollow rinsing ball involved in the Chinese patent ZL89108618 patent is not easy to wear, but the preparation cost is high, the process is complicated, and ...
