Abstract

The invention discloses a method for fabricating novel recycled bricks and relates to the field of building materials. The method for fabricating the novel recycled bricks comprises the following steps: (A) dehydrating sugar refinery filter mud with the moisture content of 50-70% until the moisture content of the sugar refinery filter mud is not higher than 30% so as to obtain dehydrated filter mud; (B) uniformly stirring the dehydrated filter mud obtained in the step (A) and slag, and grinding so as to obtain granules with the granularity of 150-200 meshes; (C) uniformly mixing the mixed granules obtained in the step (B) with cement, expanded and vitrified microbeads and a sulfur fixation and nitrogen fixation deodorizer, adding water to the mixture, and stirring uniformly so as to obtain clinker mud; and (D) preparing unburned bricks from the clinker mud, air-drying the unburned bricks, loading the unburned bricks to a kiln for sintering, and naturally cooling the burned bricks, thereby obtaining the novel recycled bricks. The method has the advantage that the novel recycled bricks which are low in cost and light in weight and are fireproof and anti-seepage are fabricated through converting the sugar refinery filter mud into resources.

Description

The making method of New Regenerated brick

Technical field

The present invention relates to building material technical field, especially a kind of making method of New Regenerated brick.

Background technology

Guangxi is as the area just at high speed development, and all our undertakings are all in construction in full swing, and the demand of construction timber sharply rises.Simultaneously Guangxi is again the tap of national sugar-refining industry, produces a large amount of filter mud the like waste every year, because these sugar refinery are nearly all adopt carbonatation process production technique, to make in filter mud, except containing except large amount of organic, to be also rich in basic carbonate calcium.The current recycling mode of these filter mud of sugar refinery is mainly done fertilizer, feed, acid soil improving agent, is produced commercial lime stone etc.But because alkalescence is high, easily harden, the sales volume doing fertilizer and feed is all little.Cannot be used up so still there is a large amount of filter mud profits, cause environmental pollution.

If these filter mud of sugar refinery can be used construction timber, not only solve the problem that filter mud pollutes, also effectively make use of filter mud resource, more can provide the novel architecture material of excellent performance and reduce its cost, economic benefit, social benefit and ecological benefits can obtain effect.

Summary of the invention

Technical problem to be solved by this invention is to provide a kind of making method of New Regenerated brick, it can solve, and filter mud of sugar refinery resource utilization produces that cost is low, quality is light, fire prevention, water-impervious the problem of New Regenerated brick.

In order to solve the problem, the technical solution adopted in the present invention is: the making method of this New Regenerated brick, it is characterized in that comprising following steps:

A, by water content be 50 ~ 70% filter mud of sugar refinery dehydration must not to dewater filter mud higher than 30% to water content;

B, get 15 ~ 30 weight parts steps A gained dehydration filter mud, 25 ~ 40 weight parts slag stir, grind to form 150 ~ 200 order particles and obtain composite grain;

C, by the cement of step B gained composite grain and 25 ~ 40 weight parts, the expanded and vitrified small ball of 10 ~ 15 weight parts, the solid sulphur fixed nitrogen peculiar smell removal agent of 4 ~ 6 weight parts mixes, and adds water and stirs make the ripe mud of adobe;

D, ripe for step C gained mud is made adobe, place 2 ~ 5 days natural air dryings, enter klining knot 60 ~ 120 minutes, sintering temperature is 800 ~ 1200 DEG C, naturally cooling and get final product.

In technique scheme, technical scheme can also be more specifically: described solid sulphur fixed nitrogen peculiar smell removal agent is made up of the calcium oxide of 94 ~ 96wt% and the salt of wormwood of 4 ~ 6wt%.

Owing to have employed technique scheme, the present invention compared with prior art has following beneficial effect:

1, raw material filter mud of sugar refinery of the present invention, slag are all trade wastes, not only be rich in a large amount of calcium carbonate, organism, fiber, or the concrete admixture of high-quality, both achieved utilization of waste as resource, again reduce cost, reach the doulbe-sides' victory of economic benefit and ecological benefits.

2, raw material of the present invention have employed expanded and vitrified small ball, and ageing resistance is strong, has the excellent performance such as thermal insulation, fire prevention, sound-absorbing, insulation.

3, the present invention after testing, and without explosion without scum, the ultimate compression strength of load face reaches 6.9MPa, is greater than GB 6.5 MPa, and 5h boils water-intake rate and saturation factor and distinguishes average out to 17.3% and 0.2, is less than GB 30% and 0.88.As can be seen here, the performance such as Novel lightweight brick resistance to compression of the present invention, fire prevention, waterproof is better.
