Embodiment 1

[0017] KP1 cement, wherein the weight ratio of each component is as follows: potassium silicate: furan resin: KP1 powder is 80:20:220. Mix all components evenly to obtain the KP1 cement.

[0018] Apply the KP1 cement to the dry suction floor of the acid system, clean the working surface first, then pickle, brush the primer, and paste the cloth, then use KP1 cement to build a 65mm thick acid-resistant layer and dry it for 7 During the drying period, it is pickled four times with dilute acid with a mass concentration of 20%, and the interval between each time is not less than four hours. After 1 year of use, corrosion and damage have not yet occurred.

Embodiment 2

[0020] KP1 cement, wherein the weight ratio of each component is as follows: potassium silicate: furan resin: KP1 powder is 80:20:200. All components are mixed together to obtain the KP1 cement.

[0021] Apply the KP1 cement to the dry suction floor of the acid system, clean the working surface first, then pickle, brush the primer, and paste the cloth, then use the KP1 cement to build a 65mm thick acid-resistant layer and dry it for 8 During the drying period, it is pickled three times with a dilute acid with a mass concentration of 15%, and the interval between each time is not less than 5 hours. After 1 year of use, corrosion and damage have not yet occurred.

Embodiment 3

[0023] KP1 cement, wherein the weight ratio of each component is as follows: potassium silicate: furan resin: KP1 powder is 80:20:240. All components are mixed together to obtain the KP1 cement.

[0024] Apply the KP1 cement to the dry suction floor of the acid system, clean the working surface first, then pickle, brush the primer, and apply the cloth, then use the KP1 cement to build a 65mm thick acid-resistant layer and dry it for 14 During the drying period, pickle with 25% dilute acid twice, with an interval of not less than 6 hours between each time. After one and a half years of use, corrosion and damage have not yet occurred.

Abstract

The invention relate to KP1 clay and the preparation method and the application thereof, belonging to the technical field of the corrosion-resistant material. The KP1 clay is prepared by mixing the following raw materials by weigh portion: 80 portions of potassium silicate, 20 portions of furan resin and 200-240 portions of KP1 powder. The KP1 clay can resist the corrosion of the concentrated sulfuric acid, the diluted sulfuric acid and the water and has strong corrosion-resistant ability and long corrosion-resistant service life.

Description

(1) Technical field [0001] The invention belongs to the technical field of corrosion-resistant materials, and in particular relates to a KP1 cement and its preparation method and application. (2) Background technology [0002] In industrial production, acidic environment is a relatively common type of working environment. Materials in this environment need to be resistant to acid corrosion. For example, in the metallurgical industry, there are many acid-making systems, and the dry-suction floor of the acid-making system puts forward higher requirements on the materials for paving the floor. For example, the current laying method of the floor is as follows: clean the working surface and clean it Finally, carry out pickling, then paint the primer, and then use KP1 cement to paste a layer of 65mm thick acid-resistant tiles. The KP1 cement composition described therein is: a mixture of potassium chlorate and KP1 rubber powder with a mass ratio of 30:70. The main component of ...
