Problems solved by technology

[0004] However, most of the existing rock wool is produced by blast furnace waste slag, which has the disadvantages of ultra-short fiber length, fear of water, easy breakage, and lack of fire resistance. Moreover, the existing technical links not only cause losses in the production process, but also the dust removal equipment is not in place. , high energy consumption, low output, high cost, and poor quality defects

Embodiment

[0017] A kind of rock wool production method, following steps:

[0018] (1) Prepare melt: select basalt tailings as raw material, add basalt, and melt into melt in a melting furnace;

[0019] (2) Making fibers: the melt is made into fibers under the drafting action of the centrifuge, and at the same time the fibers are blown to the cotton collector by high-pressure air; the slag balls are separated during the blowing process, and the binder is applied to the fiber surface.

[0020] (3) Cotton felt: the fibers form the surface layer under the action of the cotton collector. At this time, the surface layer is transported to the conveyor under the action of the pendulum machine, and multiple layers are formed on the conveyor belt of the conveyor. Cotton felt with folded layers;

[0021] (4) The above-mentioned cotton felt is produced under the effect of a pressurized pleating machine to produce structural cotton;

[0022] (5) Send the structural cotton into a curing furnace fo...

Abstract

The invention discloses a rock wool production method. The rock wool production method is characterized by comprising the following steps of first, obtaining a melt, second, obtaining fibers, third, obtaining rock wool felt, fourth, manufacturing structural rock wool, and fifth carrying out pressurization shaping. The rock wool produced through the rock wool production method has the advantages of being large in fiber length, resistant to water, not prone to breakage and resistant to fire; moreover, loss in the production process is greatly reduced, energy consumption is reduced, yield is increased, cost is further reduced, and product quality is ensured.

Description

technical field [0001] The invention belongs to a method for producing rock wool. Background technique [0002] Rock wool products are internationally recognized as the main energy-saving materials in the "fifth conventional energy source" because of their excellent fireproof and thermal insulation properties. Every ton of rock wool products used for insulation in buildings can save energy equivalent to at least 1 ton of oil a year, which is in line with the trend of low carbon, energy saving, and emission reduction, so it is an ideal building insulation material. [0003] The extensive use of rock wool for construction provides the possibility for my country to build more green and environmentally friendly buildings, protects the environment by effectively reducing energy consumption and carbon emissions, and makes due contributions to improving people's living environment. [0004] However, most of the existing rock wool is produced by blast furnace waste slag, which has ...
