Refractory

 Glass wool fibers belonging to a category. Is a man-made mineral fibers. Quartz sand, limestone, dolomite and other natural ore as the main raw material. With some soda, borax and other chemicals into the glass melt. In the molten state, by means of force. Blow thrown into the interchange standard between flocculent fine fibers, and fibers. Intertwined with each other, showing many of the small gap. This gap can be regarded as void. Thus, glass wool can be as porous material with excellent thermal insulation, sound absorption performance. The main production process centrifugal silk throwing method of manufacturing glass wool is dubbed by a certain percentage of various raw materials mix melted into molten glass in a melting furnace, the molten glass to form a stable flow through the front furnace platinum drain board, and then flows through spinning machine reaches the side wall apertures in high-speed rotation of the centrifuge. Under the influence of centrifugal force. Glass was thrown into a fiber. Then, in mixed gas on the high-speed ejection of a fiber is drawn into a glass fiber, glass fiber cotton belt of land set while spray adhesive. Then by compaction, curing, cross-cutting, slitting a certain specifications. Centrifugal glass wool glass wool devoted to various types of pipes (including: frozen hot water, steam) insulation system. It can work at not more than 454 ℃ ambient temperature, exposed. Or covered. Since the sleeves of this material has a waterproof, corrosion, mildew, and insect characteristics. Thus effectively preventing condensation. Prevent pipes from freezing. It has been widely used in civil construction. Heat pipe insulation, air conditioning, refrigeration equipment. Insulation, energy saving effect improved 15-30%. Bulk Density: 30-100kg / m3 shell inner diameter: Ф22-1220mm Thickness: 30mm-lOOmm glass wool blankets centrifugal glass wool felt is to meet the needs of large-scale laying made of membrane, in addition to maintaining the characteristics of thermal insulation, the also it has very excellent shock absorption. Sound absorption characteristics. Especially for the low-frequency noise and vibration have good absorption, helps to reduce noise pollution and improve the working environment in the construction of this material may also be arbitrarily cut, mainly used for building interior, muffler systems, vehicle , refrigeration equipment, household appliances damping, sound absorption, noise reduction, the effect is very good. Bulk density: 10-72kg / m3 Thickness: 25 a lOOmm length: 3m a 20m width: 1200mm centrifugal glass wool board centrifugal glass wool board centrifugal glass wool is made after the curing treatment of a certain strength plate products, whether in high or low temperature environment can maintain good thermal insulation properties. Mainly used for high building interior compartments. Ceiling, metal duct or bellows wall insulation, noise absorption within the room. Metal ceiling of the sweat control, has broad application prospects. Bulk density: 24-96kg / m3 Thickness: 25-l00mm Length: 600mm a 2400mm width: (Width): 600mm a 1200mm
