Problems solved by technology

[0002] In the actual production and working environment of chemical plants, engineering plastic pipes and equipment are prone to aging, deformation, and leakage after being used for a period of time. When repairing pipe leakage through traditional methods, it is generally necessary to stop the operation of the equipment for a short time, which affects normal production. Some quick plugging materials mostly contain epoxy resin, the cost is high, and there is a certain degree of toxicity

Embodiment 1

[0024] A leak-stopping material for plastic pipes and equipment, comprising the following raw materials: asbestos wool, 5kg; 325-mesh pottery clay, 9kg, and engine oil, 6.25kg; the leak-stopping material is solid at normal temperature and pressure, and can be deformed by slight extrusion .

[0025] When preparing the plugging material, first mix 50% clay and all the engine oil, then gradually add it to the asbestos wool, stir while adding, then gradually add the remaining clay, and mix well to obtain the plugging material.

Embodiment 2

[0027] A plugging material for plastic pipelines and equipment, comprising the following raw materials: asbestos wool, 4kg, 9kg of 325 mesh clay, 6.25kg of engine oil, and 3.5 kg of tung oil; the plugging material is solid at normal temperature and pressure, slightly Extrusion deformable.

[0028] When preparing the plugging material, first mix 50% clay and all the engine oil, then gradually add it to the asbestos wool, stir while adding, then gradually add the remaining clay, and mix well to obtain the plugging material.

[0029] The plugging materials obtained in the above two examples are relatively soft and have a shelf life of 30 days. They can be used for leak plugging where the pressure of pipelines and equipment is ≤49KPa. When the system pressure is high, the outer layer of the pipe can be wrapped with glass fiber cloth or wrapped with a thin iron sheet, the effect is better.

Embodiment 3

[0031] A plugging material for plastic pipelines and equipment, comprising the following raw materials: asbestos rope, 5kg; 9kg of 325 mesh pottery clay, 6.25kg of machine oil; 3 kg of tung oil, the plugging material is solid at normal temperature and pressure, slightly Extrusion deformable.

[0032] When preparing the plugging material, cut the asbestos rope into small pieces of 5-10 cm, then mix 50% clay and all the engine oil, then gradually add it to the asbestos rope, stir while adding, and then gradually add the remaining clay , and finally slowly add tung oil and mix well to obtain the plugging material.

Abstract

The invention discloses a leaking stoppage material for plastic pipelines and equipment. The leaking stoppage material comprises the following raw materials in parts by weight: 0.8 to 1.2 parts of asbestos material, 1.6 to 1.8 parts of argil, 1.25 to 1.5 parts of engine oil and 0.5 to 0.7 part of tung oil. The leaking stoppage material is solid at normal temperature and normal pressure, and can be deformed by slight extrusion. A method for preparing the leaking stoppage material comprises the following steps of: mixing the argil and the engine oil uniformly; gradually adding the mixture into the asbestos material while stirring; and slowly adding the tung oil, mixing uniformly, so as to obtain the leaking stoppage material. The leaking stoppage material is easy to prepare, remarkable in leaking stoppage effect on the plastic pipelines, the equipment and the like, low in cost and easy to popularize.

Description

technical field [0001] The invention relates to the field of pipeline plugging, in particular to a plugging material used for plastic pipelines and equipment and a production method thereof. Background technique [0002] In the actual production and working environment of chemical plants, engineering plastic pipes and equipment are prone to aging, deformation, and leakage after being used for a period of time. When repairing pipe leakage through traditional methods, it is generally necessary to stop the operation of the equipment for a short time, which affects normal production. Now Some quick plugging materials mostly contain epoxy resin, which are expensive and have certain toxicity. Contents of the invention [0003] The technical problem to be solved in the present invention is to provide a plugging material for plastic pipes and equipment and its production method. When leakage occurs in pipelines and equipment, the material can be used to timely repair leaks to ensu...
