Abstract

The invention discloses a novel process for preparing a masonry material by waste solidification treatment. The process comprises the following steps of: sorting domestic wastes, removing plastics and metals from domestic wastes and grinding to pieces with a maximum size less than 5 mm; grinding building wastes to granules with a maximum size less than 3 mm; mixing quicklime powders, sulfo-aluminate cement, gypsum powders and calcium sulphoaluminate powders to produce a solidifying agent; mixing the domestic wastes, the building wastes and the solidifying agent to form a mixed base; and loading the mixed base to a preset mould and performing pressure-molding, standing for 36 to 72 hours at room temperature and normal pressure, demoulding, and naturally curing for 28 to 30 hours, to obtain the masonry material. According to the invention, the domestic wastes and the building wastes are pretreated and then mixed with the ideal solidifying agent to produce the masonry material, so that the process of waste pretreatment is simplified to the greatest extent and the cost of waste treatment is reduced. The process has a low investment and a low cost and takes a good effect.

Description

The rubbish solidification treatment prepares the building materials novel process
Technical field
The present invention relates to refuse treatment and utilize technology, specifically a kind of processing method that the rubbish solidification treatment is prepared building materials.
Background technology
At present, the processing mode of domestic refuse is adopted usually methods such as classification recovery, landfill, burning, it is big, expensive many that these methods are produced effects less, polluted, present the processing of building waste is then adopted landfill usually, made means such as foundation.Chinese patent discloses a kind of " refuse treatment utilizes curing process ", and this technology can become building materials with the domestic refuse solidification treatment, make domestic refuse obtain the good treatment utilization, but the deficiency that this technology exists is: 1, only can handle domestic refuse, can't handle building waste; 2, the pretreated operation of domestic refuse bothers, and the pre-treatment domestic refuse need carry out pulverizing after drying or the burning to it again, and the process of processing is long, cost is bigger.
Summary of the invention
The object of the present invention is to provide a kind of rubbish solidification treatment to prepare the building materials novel process, this technology can be with domestic refuse and the common processing and utilizing of building waste, and treatment process simple, produce effects.
For achieving the above object, rubbish solidification treatment provided by the invention prepares the building materials novel process and may further comprise the steps:
A, with separating domestic garbage, reject contained plastics, metal after, be broken into the fragment of overall dimension less than 5mm;
B, building waste is ground into the particle of overall dimension less than 3mm;
C, calcium lime powder, aluminosulfate cement, gypsum powder, calcium sulphoaluminate powder are mixed, constitute peptizer, the weight part of each component of peptizer is:
Calcium lime powder 10～20, aluminosulfate cement 10～15, gypsum powder 2～5, calcium sulphoaluminate powder 2.5～5;
D, domestic refuse, building waste mixed with peptizer constitute mixed resin, the weight part of each component of mixed resin is:
Domestic refuse 4～5, building waste 2～4, peptizer 3～4;
E, mixed resin is fills up to predetermined mould inner pressure makes type, the demoulding after under normal temperature, the normal pressure 36～72 hours, natural curing 28～30 days promptly gets required building materials.
By such scheme as seen, peptizer mix with domestic refuse, building waste be pressed moulding after, through neutralization, sintering, solidify and petrochemical process finally forms mechanically resistant material, contained gypsum can play and accelerate the effect solidify in the peptizer, in the peptizer contained lime can improve first the speed of solidifying, second can play fully the nuisance in the rubbish kill livestock, decompose, dehydration, sealing process.
The present invention goes out building materials with ideal peptizer hybrid process after domestic refuse and building waste are handled a little, has simplified the pretreated step of rubbish largely, has reduced the cost of refuse treatment.This technology less investment, cost be low, produce effects.
Description of drawings
Accompanying drawing is the process flow sheet of one embodiment of the invention.
Embodiment
Further specify the present invention below in conjunction with embodiment and accompanying drawing.
Referring to accompanying drawing, the processing step of a specific embodiment of the present invention is as follows:
A, with separating domestic garbage, reject contained plastics, metal after, be broken into the fragment of overall dimension less than 5mm, described plastics mainly are meant plastics bag, waste or used plastics goods etc.;
B, larger-size blocks in the building waste is ground into the particle of overall dimension less than 3mm;
C, calcium lime powder, aluminosulfate cement, gypsum powder, calcium sulphoaluminate powder are mixed, constitute peptizer, the weight part of each component of peptizer is:
Calcium lime powder 15, aluminosulfate cement 12.5, gypsum powder 3, calcium sulphoaluminate powder 3.5,
The granularity of calcium lime powder, gypsum powder, calcium sulphoaluminate powder is 70～90 orders, is good with 80 orders generally;
D, domestic refuse, building waste mixed with peptizer constitute mixed resin, the weight part of each component of mixed resin is:
Domestic refuse 4.5 building wastes 3 peptizer 3.5
E, mixed resin is fills up to predetermined mould inner pressure makes type, the demoulding after under normal temperature, the normal pressure 48 hours, natural curing 28 days promptly gets required building materials.
The building materials that is obtained by technology provided by the invention has purposes more widely, as be used for the shop build highway, build the basis, place, make light wall board, make drainage pipeline, make floor tile etc.
