Description

(54) RAW MATERIAL MIXTURE FOR OBTAINING CERAMSITE

   -. one

The invention relates to the technology of building materials, and names to compositions for the production of expanded clay.

The well-known raw material mixture for the production of expanded clay, including clay raw material 40-90%, slag metallurgical production of copper 10-60%. Bulk weight of claydite is 0.537.

The closest to the technical essence and the achieved effect to the invention is the raw mix for the production of expanded clay, including clay raw materials and oil 3% 12.

The disadvantage of these mixtures is high volumetric weight.

The purpose of the invention is to reduce the bulk weight of expanded clay.

The goal is achieved by the fact that the raw mix for the production of expanded clay, including clay raw material and intumescent additive, contains as an intumescent additive drilling mud in the following ratio of components, wt.%:

Clay raw materials 50-99.9

Spent drilling mud 0,1-50

Waste drilling mud, iron compounds, has the following composition (wt.%):

Solid phase (clay, drilled rock and ferruginous bit) 3-80 Oil 5-25

Organic regulators of rheological properties, filtration and stabilization (CMC, hypan, oxyl, etc.) 0.01-5 pH regulators

The spent drilling mud is a highly dispersed composition of a whole range of reagents,

5 which increase the swelling of clays, which leads to a decrease in the bulk weight of keers and improvement of its other indicators. In addition, the batch solution strongly plasticizes the clay and is much easier to process than isholnap clay. Due to the burnout of oil and organic reagents, fuel consumption is reduced, the torch penetrates deeper into the kiln, which facilitates firing. The drilling fluid is mixed with clay, then the mixture is fed into a clay mixer, where it is mixed to the desired consistency and molded. Firing lead when. Example 1. Preparing a raw mix containing, wt%: clay raw materials 96.4, spent drilling mud 3.6. . The average volume-bulk v.es 371 kg / m, strength 16 kg /

The average volume and bulk density is 371 kg / m5.

The second and third examples are taken according to the laboratory data for the firing of expanded clay gravel in a muffle furnace at 1100-1200 ° C. Example 2. A raw mix is prepared containing 99.9% of clay and 0.1% of spent drilling mud. With this ratio of ingredients, the average volume weight is 450 g / cm, gravity strength is 23 kg / cm. Example 3. Prepare a raw mix containing 50% of career clay and 50% of spent drilling mud. At this ratio, the average volumetric volume is 280 g / cm, the strength of the gravity is 8 g / cm. The table shows the results of laboratory tests of expanded clay.
