In the following description of the present invention, detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear.

The present invention is a building finish material containing rice husks and rice bran mixed with 3% to 50% by weight of rice husks, 15 to 30% by weight of rice bran, 10 to 20% by weight of abrasive grains and 20 to 30% Is mixed with water, compressed in a molding mold, and heated to form a ceiling duct and a construction material finishing material.

Hereinafter, characteristics and effects of the rice husk, rice bran, and stoneware used in the method for producing the building finish material containing rice hull and rice husk according to the present invention will be briefly described.

First, the rice husk is the first bark of the rice that is peeled off from the outside of the rice. It is the shell that encloses the rice. It uses the rice husk to burn the rice husk charcoal or rice husk to make the sucker. It contains more than 200 kinds of organic compounds such as acetic acid and phenol in the extract solution which is extracted and recovered from the carbonization process. It is good for the global environment and is used for civil treatment such as athlete's foot and atopic dermatitis.

Rice husks keep air and water, and contain little nitrogen fertilizer, do not produce spoilage bacteria, and appear to be rigid at first sight. However, inside of pear shape is soft, It is easy to use because it decomposes slowly in the soil. When it is mixed with soil, chaff that is mixed with soil absorbs and retains moisture and is used as an easy resource for soil.

Unlike ordinary rice husk, unlike general rice husk, it has high water absorption ability and high temperature and high pressure processing, it completely becomes a state that weeds seeds, parasites and various bacterium are completely killed, (More than 67%) and silicic acid (more than 8%). It is easy to handle because it is light in weight and low in price.

Especially, silicate of puffy rice husk is vegetable and absorbability, so it is more effective than mineral silicate. Organic fertilizer made of puffy rice husk is used as a completely natural farm material to prevent acidification of farmland, obstruction of cropping, accumulation of salt and so on.

The rice husk is used as a charcoal for burning chaff, and has excellent effect on crop growth and soil improvement by fine pores and various minerals. Chaff charcoal, which is organic (more than 57%) and siliceous (more than 33%), When sprayed, the plant's roots reach and become stronger due to the characteristics of minerals and microorganisms. In particular, the rooting power of the rootstock is improved and the absorption power is increased.
