In the prior art, if you want to form a bubble structure in the product, you can use the following methods: 1. Add metal aluminum and alkali in the process. The hydrogen gas is generated by the reaction of these two elements, and the hydrogen gas is retained in the product. Becomes the source of bubble formation. 2. Add foaming agents such as surfactants or greases to the mud-like substance, and generate bubbles during the mixing process and stay in the mud. 3. Use the material with foaming ability to directly add to the mud and mix and stir to form bubbles directly. 4. Add some organic fiber substances in the process of producing ceramics, and the organic fibers will be burnt out during the sintering process of ceramics, and will remain as voids. 5. The foaming resin is used as the base material, and the ceramic slurry is incorporated therein; the sintering process is also performed to make the ceramic sintered body with holes. In the above several methods, the bubbles of items 1 to 3 exist in the mixture in advance and form pores as the mixture solidifies; and the size of paper 4 to 5 applies to the Chinese National Standard (CNS) A4 specification (210 ×: 297 mm) (Please read the notes on the back before filling this page)

In the description of item (a), stomata are formed after firing; the bubbles formed by the former are independent bubbles that are not connected to each other (as shown in the first figure) ), The latter is capillary-shaped, and the tube body is a through-air bubble penetrating from the inside to the outer layer (as shown in the second picture). Among the several existing methods for manufacturing bubble structure, the first lightweight cement with metallic aluminum and alkali added to the cement has a maximum compressive strength of 50 kg / on after setting and a maximum of 2 Okg / c / Unless such strength is reinforced by built-in steel bars, the forming area exceeding 900 Yuan X 900 can not be used; furthermore, because its composition is only metal aluminum, calcium acetate and other compounds, it has been frozen and thawed for a long time. Invasion, the texture is easy to oxidize and deteriorate, and it is not suitable for outdoor environment. In addition, most of its bubbles are independent spherical bubbles with a diameter of about lm, which is only suitable for indoor sound insulation materials. The second method is to add foaming agents such as surfactants or oils to form bubbles. Because there are too many independent bubbles, their use is very limited, and most of them are only used as lightweight materials. The third kind of bubble formed by directly stirring the bubble material is too large, and it is impossible to achieve fine bubbles with a size of less than 101 Utm. The fourth method of stomata formation by burning the two organic compounds is mostly used for water permeability. The fifth method uses the foaming resin to impregnate the ceramic slurry. Its products are mainly used as filter materials for metal melting furnaces, which have the characteristics of high temperature resistance. < Solutions > In view of the fact that the bubble structure produced by the existing technology is either insufficient in strength and poor in weatherability, or the number of bubbles or the size is too large to affect its use, it has a suitable capillary. But the bubble-like tissue can not provide the ability to absorb sound; therefore, the present invention is to provide a paper with a scale from low frequency to high paper music applicable to the Chinese national standard {CNS) Λ4 specification (210X297 mm) (谙 Read the precautions on the back first (Fill in this page again.)

Description of the invention (5) Ming Huan. Furthermore, the glass chips, fly ash, and clays added in the manufacturing method of the present invention are used to fix the shape of bubbles and promote hardening; because when the ratio of water to cement is in the range of 0.7 to 1.0 during implementation, the cement slurry hardens The speed is relatively slow, and the air bubbles formed at this time are easy to burst. Therefore, the addition of the top material as a hardening accelerator will accelerate the hardening speed of the cement slurry. The same materials as the above hardening accelerators include calcium chloride (CaCl) and hydraulic aluminum 1% ~ 0.2% of synthetic resin-based polymers (C3A, C / 2A, CA), calcium acetate strips (CA3SiOs (C3S), CaSi03 (CS) and white cement, etc.) Adhesive, & helps to adjust the bubble content.
