Rock wool and method for producing and manufacturing rock wool

Abstract

The invention discloses rock wool. The rock wool is prepared from the following raw materials in parts by weight: 390 parts of basalt, 60 parts of slag, 70 parts of dolomite, 0.7 part of a water repellent and auxiliary materials. According to the rock wool and the method for producing and manufacturing the rock wool in the invention, the basalt, the dolomite and the slag in the raw materials are crushed to particle size ranges of 80-120 mm, 40-60 mm and 60-100 mm, respectively, so the melting speeds of the basalt, the dolomite and the slag in a cupola furnace are guaranteed to be similar, andthe melting efficiency of the basalt, the dolomite and the slag and mixing effect after melting are improved to the maximum extent; and molten liquid passes through an adjustable launder to form a stable stream, the stable stream is conveyed to a wire roller centrifugal machine for thread throwing to prepare fibers, and the quality of the made fibers is improved.

Description

technical field [0001] The invention relates to the technical field of rock wool, in particular to a rock wool and a method for producing rock wool. Background technique [0002] Rock wool originated in Hawaii. After the first volcanic eruption on Hawaii Island, residents on the island found strands of melted soft rocks on the ground. This is the rock wool fiber that humans first recognized, and the production of rock wool The process actually simulates the natural process of Hawaiian volcanic eruption. Rock wool products are made of high-quality basalt and dolomite as the main raw materials. After spraying a certain amount of binder, dust-proof oil, and water-repellent agent, it is collected by the cotton collector, passed through the pendulum method, and then solidified and cut by the three-dimensional method to form rock wool products of different specifications and uses. [0003] The rock wool currently used in the market and the method of producing rock wool, in the pr...

AI Technical Summary

Problems solved by technology

[0003] The rock wool currently used in the market and the method of producing rock wool, in the process of rock wool production and preparation, when the principle is melted, due to the different particle sizes and uneven particle sizes of each component cost, it is easy to affect its melting efficiency and after melting. The uniformity of mixing, and secondly, directly transport the melted solution to the silk roller centrifuge for spinning to make fibers. Since the solution does not form a stable stream, it is easy to affect the effect of spinning, so it cannot meet the needs of users.
