Problems solved by technology

However, there are some disadvantages in using cement as a bonding agent: 1. The hydration and solidification of cement requires a sufficient amount of water, but it cannot avoid the volatilization of part of the water and leaves pores, resulting in insufficient compactness of the overall structure and insufficient stain resistance.
These shortcomings are one of the reasons why the market share of inorganic artificial stone is not high

Embodiment 1

[0061] (1) Mixing, add the dry mixed material into the airtight stirring tank, close the feeding port at the top, set the mixer at 50r / min and stir for 3min to pre-mix the dry material, and then set the speed at 600r / min Make the materials in the stirring tank tumbling, and at the same time, the 4 built-in sprayers on the top of the stirring tank start to spray atomized water at a flow rate of 1L / min. After the water is sprayed, continue to stir for 3 minutes, and the material mixing is completed.

[0062] (2) Cloth, open the outlet at the bottom of the closed stirring tank, so that the mixture falls into a pile at the center of the square mold below. , there is equipment for paving the mixture in this position - a square comb rake, a square comb rake is a square steel plate fixed with many round-headed steel bars perpendicular to the steel plate. The initial position of the square rake is above the center of the mould. After the mold is in place, the square rake descends and ...

Embodiment 2

[0071] This example is used as a control group to verify the effect of step 6 treatment. This example 2 adopts the same manufacturing process as that of example 1, except that step 6 is skipped, and the pressed rough billet is made into a middle billet after rough grinding in step 5. Finally, skip the spray hardener and go directly to the fine grinding of step 7, and complete the remaining steps to obtain sample 2.

[0072] The gloss, surface Mohs hardness, stain resistance and efflorescence of test example 1 and embodiment 2 inorganic artificial stone samples, gloss test, surface Mohs hardness test and stain resistance test are all according to JCT 908-2013 artificial stone The test method in the standard is carried out, and the test method below is the same, and the test results are shown in Table 1.

[0073] Table 1

[0074] Moh's hardness luster Pollution resistance index pan-alkaline condition sample 1 6 34 82 ubiquitine-free sample 2 6 ...

Embodiment 3

[0077] This embodiment is used to observe the influence of the spray pressure, the flow rate of a single shower head and the spray time on the performance of the sample in step 6. This embodiment 3 adopts the same manufacturing process as that of embodiment 1, completes steps 1, 2, 3, 4, and 5 to obtain the middle billet, and sets the parameters of step 6 as the hydraulic pressure of a single nozzle is 0.1MPa, and the flow rate of a single nozzle is 6L / h, the spraying time is 4h, after the spraying is over, wash and dry. Complete steps 7, 8, and 9 to obtain the finished product, and sample 3 is obtained.

Abstract

The invention discloses a hardener spraying device for inorganic artificial stone and an inorganic artificial stone manufacturing method. The hardener spraying device comprises a spraying table and a spray head assembly, the spraying table comprises a table frame and a turnover assembly, a to-be-sprayed object is limited on a turnover part, the spray head assembly is provided with a plurality of spray heads, and the spray heads are arranged perpendicular to the surface of the to-be-sprayed object. The inorganic artificial stone manufacturing method comprises the following steps that an inorganic artificial stone middle blank is obtained; the middle blank is placed on the hardener spraying device for the inorganic artificial stone; the spraying device is started, and a hardener is sprayed to the surface of the middle blank; after spraying is finished, cleaning and drying are carried out; and after drying, fine grinding, cutting and polishing are conducted, and the inorganic artificial stone is obtained. According to the method, a manufacturing process of the spraying hardener is newly added, and silicon dioxide in the hardener and an unreacted cementing material in an inorganic artificial stone plate are subjected to a continuous chemical reaction, so that the hardness and the water resistance of the material are improved, the saltpetering problem is solved, and meanwhile, the advantages of safety and environmental protection of the inorganic artificial stone are preserved.

Description

technical field [0001] The invention belongs to the technical field of inorganic artificial stones, and in particular relates to a hardener spraying device for inorganic artificial stones and a method for making inorganic artificial stones. Background technique [0002] Stone is the first choice for decoration of high-end buildings, because of its beautiful patterns and heavy texture, it gives people a high-end, comfortable and reliable feeling. The mainstream stone in the market is divided into natural stone and organic artificial stone. However, organic artificial stone and natural stone have many defects. The problems of natural stone are color difference, poor chemical resistance, and poor mechanical strength. They can only be used as wall decoration for high-end occasions. Organic artificial stone is good in all aspects, but it involves organic volatiles, high temperature resistance and fire prevention, and there are safety and environmental protection problems. Howeve...
