Production technology of inorganic fiber thermal insulation material by using industrial waste slag

Abstract

The invention belongs to the technical field of inorganic fiber heat preservation materials, and provides a production technology of using industrial waste residues for producing an inorganic fiber heat preservation material. The production technology includes the steps that ferronickel waste residues, or manganese-silicon alloy waste residues, or phosphorous slag waste residues or air-added brick waste residues or blast furnace water granulated slag, dolomite dust and silica powder are mixed into a mixture with the acidity coefficient MK ranging from 1.6 to 2.2, a binding agent is added into the mixture, the new mixture is conveyed into a forming machine to be pressed into blocky formed objects, and smelted in a smelting furnace, fiber forming through high-pressure centrifugal blowing and pulling, cotton collecting through a fiber catching machine, cotton distributing through a pendulum bob, wrinkling through a wrinkling machine, and heating and forming through a sheet baking machine are conducted to produce the inorganic fiber heat preservation material with the heat preserving, heat insulating, waterproof and soundproof functions. The technical problems that in the prior art, the industrial waste residues such as the ferronickel waste residues, the manganese-silicon alloy waste residues, the phosphorous slag waste residues, the air-added brick waste residues and the blast furnace water granulated slag are difficult to recover and use, the waste residues and waste are low in use ratio, the inorganic heat preservation material is high in production cost, and resource integration is low in efficiency and unreasonable are solved.

Description

technical field [0001] The invention belongs to the technical field of inorganic fiber thermal insulation materials, and relates to a production process for producing inorganic fiber thermal insulation materials by utilizing industrial waste residues. Background technique [0002] Ferronickel waste slag, phosphorus slag waste, manganese-silicon alloy waste slag, aerated brick waste slag, blast furnace slag and other industrial waste slag are industrial solid wastes. These waste slags are not easy to handle, and they are easy to cause environmental problems when they accumulate in large quantities. These industrial waste slags The recycling of energy is still a worldwide problem. In response to the current situation of the global energy crisis, countries around the world are actively developing and applying energy-saving technologies in various fields. In the field of building energy conservation, wall insulation is regarded by governments and experts as the most effective me...
