Pyongyang, January 20 (KCNA) -- The technical research group of the Korea Rason Taehung Trading Company has recently succeeded in developing a new kind of inorganic foaming material by using coal muck as principal raw material. It is considered as an ideal building material. It is effective for waterproofing, moisture-proofing, soundproofing, heat insulation, fire-fighting and shutting out laser, infrared and radiation rays. It stands high temperature and strongly resists acid, alkaline and salt solutions and natural corrosion. It is possible to make products different in size and quantity, pressure, heat conduction, soundproof, etc. by adjusting the utility rate of the above-said material according to diverse uses. When it is used as material for building underground structures, flat roofs and walls it can be melted by oxygen to have construction material without using joints. This material can be used as fireproof and material for lagging for building different types of furnaces in the field of metal industry and boilers. It also helps ensure the quality of buildings in the construction of prefabricated structuging ulation, of al industry and boilerss uses. |
