Embodiment Construction

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention.

[0032] refer to figure 1 , a kind of rock wool, the rock wool includes the following raw materials by weight: 390 parts of basalt, 60 parts of slag, 70 parts of dolomite, 0.7 part of water-repellent agent and auxiliary materials.

[0033] Accessories include adhesives and anti-dust oil.

[0034] The main components of basalt are silicon dioxide, aluminum oxide, iron oxide, calcium oxide, and magnesium oxide, among which silicon dioxide has the most content, accounting for about 45% to 50%.

[0035] Slag is a by-product of the blast furnace ironmaking process. In the ironmaking process, iron oxide is reduced to metallic iron at high temperature. Impurities such as si...

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...
