Method for preparing microcrystalline glass water washing ball

Abstract

The present invention provides a method which is used for preparing a nucleated glass flush sphere and comprises the procedures of batching, molding and baking, and the method has the following characters: 50-94% powdered glass with granularity 5 mu m to 300 mu m, 2-15wt% sodium silicofluoride, 2-15wt% diborate and 1-10wt% nucleating agent and 1-10wt% foaming agent is mixed according to the proportion and is grinded to prepare the homogeneous nucleated glass powder, then the nucleated glass powder is prepared to flush sphere base substrate, the base substrate is baked for 1-4 hours at the temperature 600-950 DEG C after drying, and the nucleated glass powder sphere is prepared. The technique of the invention is simple, the nucleating agent is added to promote the crystal growth in the baking process, the kind of the nucleating agent, adding amount, temperature and baking time are controlled thereby controlling the volume content of the crystal and the crystal size in the product thereby obtaining the purpose of improving the product strength, the pore diameter of the product can be controlled between 0.1 and 0.5mm, and the inside and outside arrangement is uniform, the cost is lowand the performance is excellent, the cubic effect of the washed cloth decorative pattern is excellent and the appearance is beautiful.

Description

Technical field

[0001] The invention relates to a preparation method of glass-ceramic washing balls, and belongs 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 the color...
