Problems solved by technology

[0002] Boilers, tea stoves and other heating and heat exchange equipment will inevitably have scale and corrosion after long-term operation, resulting in fuel waste and even accidents; oil stains, dirt, and urine stains are often encountered in daily life facilities and are difficult to remove. stains
In order to remove these scale layers, the traditional method is to use hydrochloric acid or nitric acid for descaling. Although it can play a role in descaling, strong acids are strongly corrosive to metals and easily destroy the molecular structure of the metal surface. Metal surfaces will rust and scale quickly
In addition, because hydrochloric acid or nitric acid is harmful to the human body, you must be careful when descaling, and there are potential safety hazards
Especially the acid mist produced when using high-strength hydrochloric acid or nitric acid not only has a strong stimulation to the human body, but also pollutes the air; the discharge of waste acid water will also seriously pollute water resources and damage the ecological environment

Embodiment 1

[0041] (1) Weigh the following raw materials according to the components in Example 1 of Table 1: trisodium phosphate, urea, industrial salt (sodium chloride) and ethylenediaminetetraacetic acid. The amount of water is based on the dissolution of all the raw materials, and the semi-finished aqueous solutions are respectively prepared;

[0042] (2) release the phosphoric acid into a diluted aqueous solution, and the phosphoric acid adopts 85% concentrated phosphoric acid;

[0043] (3) Mixing and stirring the semi-finished aqueous solution in step (1) in turn, then adding the phosphoric acid diluted aqueous solution in step (2), and finally adding polyethylene glycol, polymer composite synergistic active agent, and fatty alcohol polyoxyethylene ether, add enough water in the stated proportion, and stir evenly to make a multi-purpose descaling liquid.

[0044] In the present invention, the consumption of each raw material is obtained through a lot of groping and summarization by...

Abstract

The invention discloses environment-friendly multi-purpose descaling liquid. The environment-friendly multi-purpose descaling liquid is used for removing water scales, oil scales, dirt and urine scales, and the key is that the environment-friendly multi-purpose descaling liquid is prepared from the following raw materials in percentage by weight: 2-7% of trisodium phosphate, 8-15% of phosphoric acid, 2-7% of polyethylene glycol, 3-8% of urea, 2-7% of industrial salt, 7-13% of a polymer composite synergistic active agent, 1-5% of ethylene diamine tetraacetic acid, 3-8% of fatty alcohol polyoxyethylene ether and the balance of water. The multi-purpose descaling liquid can rapidly remove the scales and has the advantages of good descaling effect, no irritation and no harm to human bodies, safety, no toxicity and no environmental pollution.

Description

technical field [0001] The invention belongs to the technical field of chemical descaling, and in particular relates to an environment-friendly multipurpose descaling liquid for removing scale, grease, dirt and urine scale. Background technique [0002] After long-term operation of heating and heat exchange equipment such as boilers and tea stoves, scale and rust will inevitably occur, resulting in fuel waste and even accidents; and oil scale, dirt, and urine scale are often encountered in daily life facilities and are difficult to remove. stains. In order to remove these scale layers, the traditional method is to use hydrochloric acid or nitric acid for descaling. Although it can play a role in descaling, strong acid is strongly corrosive to metals, and it is easy to destroy the molecular structure of the metal surface. Metal surfaces can quickly rust and scale again. In addition, since hydrochloric acid or nitric acid is harmful to the human body, care must be taken wh...
