[0022] In this embodiment, its proportioning is: 40 parts of bamboo powder, 60 parts of diatomaceous earth, 5 parts of water-soluble polymer binder. Electron microscope picture of bamboo powder figure 1 As shown, the electron microscope picture of diatomite raw material is as follows figure 2 shown.

[0023] The preparation method of this bamboo charcoal diatomite composite ceramic material comprises the following steps:

[0024] (1) drying the bamboo powder at 60-80°C for 1-2 hours, and passing through a 200-mesh sieve;

[0025] (2) Dry diatomaceous earth at 60-80°C for 1-2 hours, and pass through a 200-mesh sieve;

[0026] (3) Mix 5 parts of water-soluble polymer binder with 100 parts of water, fully dissolve;

[0027] (4) The raw material ...

Embodiment 2

[0041] A bamboo charcoal bentonite composite ceramic material is prepared from the following raw materials in parts by weight: 10-90 parts of bamboo powder, 10-90 parts of diatomite, and 5-20 parts of water-soluble polymer binder.

[0042] In this embodiment, the proportioning ratio is: 20 parts of bamboo powder, 70 parts of diatomaceous earth, and 10 parts of water-soluble polymer binder.

[0043] Refer to Example 1 for preparation and experimental methods.

[0044] After testing, the performance parameters of the product prepared in this embodiment are as follows:

[0045] The specific surface area is greater than 80m 2 / g; compressive strength greater than 11Mpa; porosity greater than 60%, filtration rate 28ml / hr.cm 2 (Water level drop 300mm). The effective removal rate of hexavalent chromium is between 85% and 95%.

[0046] It can be seen that increasing the proportion of diatomite increases the hardness of the product, and decreasing the proportion of bamboo powder de...

Embodiment 3

[0048] A bamboo charcoal bentonite composite ceramic material is prepared from the following raw materials in parts by weight: 10-90 parts of bamboo powder, 10-90 parts of diatomite, and 5-20 parts of water-soluble polymer binder.

[0049] In this embodiment, its proportioning is: 60 parts of bamboo powder, 40 parts of diatomaceous earth, 20 parts of water-soluble polymer binder.

[0050] Refer to Example 1 for preparation and experimental methods.

[0051] After testing, the performance parameters of the product prepared in this embodiment are as follows:

[0052]The specific surface area is greater than 110m 2 / g; compressive strength greater than 5Mpa; porosity greater than 70%, filtration rate 35ml / hr.cm 2 (Water level drop 300mm). The effective removal rate of hexavalent chromium is between 95% and 100%.

[0053] It can be seen that reducing the proportion of diatomite reduces the hardness of the product, and increasing the proportion of bamboo powder increases the ad...

Abstract

The invention relates to a bamboo charcoal-diatomite-bentonite composite ceramic material and a preparation method thereof. A bamboo charcoal-diatomite composite ceramic material is prepared from the following raw materials in parts by weight: 10-90 parts of bamboo powder, 10-90 parts of diatomite and 5-20 parts of a water-soluble macromolecular binder. The preparation method of the bamboo charcoal-diatomite composite ceramic material comprises the following steps: (1), oven-drying the bamboo powder for 1-2 hours at 60-80 DEG C, and making the bamboo powder pass through a 200-mesh sieve; (2), oven-drying the diatomite for 1-2 hours at 60-80 DEG C, and making the diatomite pass through the 200-mesh sieve; (3), mixing the 5-20 parts of water-soluble macromolecular binder with 100-110 parts of water, and sufficiently dissolving the water-soluble macromolecular binder; (4), carrying out mixing in a proportion of the 10-90 parts of bamboo powder to the 10-90 parts of diatomite in a solution obtained in the step (3), and obtaining a mixture; (5), ball-milling the mixture, obtaining slurry, putting the slurry in a vacuum, and removing air bubbles; (6), making the slurry stand and cured, and then granulating and molding the slurry; (7), heating up and calcining a green body, and then cooling the green body to a room temperature. The preparation process of the bamboo charcoal-diatomite composite ceramic material is economical and environment-friendly; a ceramic material with many orifices, a large specific surface area and high adsorption capacity can be prepared and obtained.

Description

technical field [0001] The invention belongs to the technical field of processing bamboo charcoal diatomite composite ceramics, in particular to a bamboo charcoal diatomite bentonite composite ceramic material and a preparation method thereof. Background technique [0002] Diatomaceous earth is a siliceous rock, a biogenic siliceous sedimentary rock composed primarily of the remains of ancient diatoms. Its chemical composition is SiO 2 It is a natural porous material mainly composed of silica, which has a series of advantages such as good chemical stability and high specific surface area. [0003] Bamboo charcoal is an excellent adsorption material, which has the advantages of many pores, large specific surface area, and strong adsorption capacity. Moreover, the raw material of bamboo charcoal, bamboo, has a short growth period and abundant sources, so that bamboo charcoal is widely used in water treatment and air filtration and other fields. The invention with the applica...
