Problems solved by technology

[0002] At present, in the leakage maintenance of 93%-105% sulfuric acid production and storage equipment, the materials used are usually ordinary materials such as KPI cement. Although the acid resistance is good, due to the problem of the material itself, it will appear porous after curing. Sulfuric acid will corrode the shell when the equipment is running, causing equipment leakage, affecting the normal production and the service life of the equipment

Embodiment 1

[0017] Embodiment 1: A semi-solid composite restoration material, including a binder and a catalyst in a weight ratio of 100:10.

[0018] The binder includes 10%-20% by weight of polytetrafluoroethylene powder with a particle size of less than 10 microns, 10%-20% of nylon powder, 40%-60% of potassium silicate composite material, 6%-10% ultra-fine diabase powder, 4%-6% ultra-fine quartz powder with a mesh size less than 300 mesh, 3%-4% diatomite, and 3%-4% sodium metasilicate.

[0019] Described catalyst is aluminum phosphate (AlPO 4 ).

[0020] The potassium silicate composite material is a potassium silicate composite material obtained by adding 5% aluminum borate to potassium silicate for anion composite modification. The method for modifying the potassium silicate composite material is as follows: at room temperature, add 5% aluminum borate to the potassium silicate aqueous solution, and stir thoroughly until there is no precipitation at rest.

Embodiment 2

[0021] Embodiment 2: the same as Embodiment 1, except that it is a semi-solid composite restoration material, including a binder and a catalyst in a ratio of parts by weight of 100:11.

Embodiment 3

[0022] Embodiment 3: Same as Embodiment 1, a semi-solid composite restoration material includes a binder and a catalyst in a ratio of parts by weight of 100:12.

Abstract

The invention relates to a special material for the leakage stoppage technology of a sulfuric acid medium device. A semisolid composite repair material comprises an adhesive and a catalyst the ratio of which by weight is 100: 10-15. The invention further provides a preparation method of the semisolid composite repair material, which comprises the following steps: the adhesive is poured into a stirring tank, and then injected into a reaction kettle for preparing the solution-like adhesive; the powder catalyst in 180 meshes-200 meshes is prepared by aluminum phosphate; and the solution-like adhesive and the catalyst in the two steps are mixed according to the proportion for preparing the semisolid composite repair material at normal temperature and normal pressure. The technology is mainly used for repairing parts with leakage of towers, grooves and tanks in sulfuric acid devices, the effects are good, and the operation and the use are convenient.

Description

technical field [0001] The invention relates to a special material for plugging technology of sulfuric acid medium equipment. Background technique [0002] At present, in the leakage maintenance of 93%-105% sulfuric acid production and storage equipment, the materials used are usually ordinary materials such as KPI cement. Although the acid resistance is good, due to the problem of the material itself, it will appear porous after curing. Sulfuric acid in equipment operation will corrode the shell, cause equipment leakage, and affect the normal production and service life of the equipment. Contents of the invention [0003] The purpose of the present invention is to avoid the disadvantages of the prior art and provide a semi-solid composite restoration material with good acid resistance and long service life. [0004] In order to achieve the above object, the technical solution adopted by the present invention is: a semi-solid composite repair material, including a binder ...
