Problems solved by technology

[0005] a. Affect the quality of subsequent spinning: using slag, steel slag and other industrial wastes as raw materials, the fibers extracted are relatively thick, and after they are finally solidified into fiber cotton, the performance of heat preservation, heat insulation, sound insulation and ventilation is not good, and the finished product of fiber cotton lower quality
[0006] b. Affect the number of subsequent spinning: when industrial waste such as slag and steel slag is used as raw materials, the number of spinning is limited, the fiber formation rate is low, and the cost is high
[0007] In short, the existing fiber cotton made of slag and steel slag as the main raw materials has the disadvantages of poor quality and low fiber formation rate, and needs to be improved.

Embodiment Construction

[0025] What the present invention discloses is a kind of method utilizing fly ash to produce fiber cotton, such as figure 1 Shown, described method comprises the following steps:

[0026] 1) Synthetic granulation of raw material fly ash:

[0027] The fly ash is synthesized into granules through a molding machine, and several through holes can be set on the shaped granules. The purpose of setting the through holes is to increase the air permeability of the granules, so that the shaped granules can be burned more thoroughly during subsequent high-temperature melting .

[0028] 2) Raw material mixing:

[0029] Mix the above-mentioned granular fly ash, calcium stone and coke. The mixing ratio varies according to the source of fly ash. Usually, it is: 90% of fly ash and 1% of calcium stone in terms of weight ratio. 2%, coke 8% to 9%. And no matter how much the content of fly ash is, the content of calcium oxide in the fly ash is preferably 20-25% by weight, and the content of s...

Abstract

The invention discloses a method for producing cellucotton by using fly ash, which comprises the following: 1) a step of synthesizing and granulating the fly ash serving as a raw material, in which the fly ash are formed into grains in a forming machine; 2), a step of mixing the raw materials, in which the calspar, white rock or basalt, the granular fly ash and coke; 3) a step of melting at high temperature, in which the raw materials are delivered to a high-temperature smelting furnace to be heated and melted; 4) a step of drawing fibers and producing cellucotton, in which the molten liquid is delivered to a high-speed centrifugal drawing machine to be drawn into fibers, and the fibers drawn out are gossypine cellucotton; and 5) a step of curing fibers, in which the gossypine fibers are stacked and added with curing agent to be cured into blocks and plates, which are blocky or platy cellucotton. The cellucotton manufactured by the method has fine fibers, high fiber yield and better heat-preservation, heat-insulation, sound-insulation, breathable performances and other performances than cellucotton manufactured by using mineral slag and steel slag as main raw materials.

Description

technical field [0001] The invention relates to a method for producing fiber cotton, in particular to a method for producing fiber cotton by using fly ash. Background technique [0002] 70% of the building materials in our country are wall materials, among which clay bricks occupy the dominant position. The production of clay bricks consumes more than 1 billion cubic meters of clay resources every year, which is equivalent to destroying 500,000 mu of land. For our big country that only accounts for 7% of the world's arable land but feeds 22% of the world's population, the significance of protecting arable land It is conceivable. At the same time, the annual production of clay bricks in my country needs to consume more than 70 million tons of standard coal, which will consume a large amount of non-renewable energy. In order to protect cultivated land and reduce the consumption of non-renewable energy, the state has formulated a series of wall material reform policies and ba...
