Description
Technical Field
The application relates to the technical field of cleaning agents, and particularly relates to a dredging cleaning agent and a preparation method thereof.
Background
Because China has a lot of terrains of mountains and hills, tunnels are the most common construction projects in order to save construction cost when traffic lines are constructed. Tunnels are generally constructed on mountains or underground, and water leakage of different degrees exists in many times. Particularly, in a karst area, the geological conditions are complex, and when tunnel engineering passes through the karst area, the construction safety and later-stage operation of the tunnel are seriously influenced by the existence of the karst. In order to avoid and reduce the damage of karst water to the tunnel engineering, Chinese tunnel workers use a molded concrete lining as a basic measure for water prevention and water blockage, and then manually set a drainage system to drain underground leaked water out of the tunnel, so that the safety of the tunnel is ensured to a great extent. Most of the existing water-proof and drainage facilities adopt a mode of longitudinally and annularly laying drainage blind pipes for drainage, and after a period of time, the drainage blind pipes are blocked by plugs to lose the drainage effect.
The reason that the tunnel drainage blind pipe is blocked is mainly that the soluble carbonate rock forms karst crystals through the actions of dissolution erosion, hydraulic transportation, crystallization deposition and the like, and the karst crystals can completely block the water permeable holes in the drainage blind pipe along with the accumulation and superposition of time. Underground accumulated water cannot be discharged through the drainage blind pipe in time, can be accumulated behind the tunnel lining, and can seep water and leak water in the tunnel when the water pressure accumulation is too large, so that the service life of the tunnel is greatly shortened, and serious threats are brought to the structural safety and long-term operation of tunnel engineering. Therefore, how to remove the karst crystals without affecting the tunnel drainage blind pipe and the peripheral concrete lining waterproof system is an urgent problem to be solved.

Aiming at tunnel diseases caused by blocking of tunnel drainage pipes, common solutions are as follows: arranging a drainage tunnel and an extension side ditch; detecting the reinforcing effect of the goaf of the karst tunnel by using an electrical sounding method and an electromagnetic wave tomography technology; the invention provides a water leakage minimally-invasive technology for a tunnel construction joint and the like by combining a limestone area tunnel defect diagnosis method. These methods belong to physical treatment methods, and are usually remedial measures performed after the tunnel structure has been damaged, and do not perform early prevention and treatment of damage.
As for the early prevention and treatment method, there is a chemical treatment method, namely, crystals which are difficult to dissolve in water are converted into soluble ions through chemical reaction by utilizing the principle of acid-base neutralization reaction. However, many acids inevitably come into contact with concrete linings, PVC plastic drainage plates and plastic drainage blind pipes during the process of dissolving the karst crystals, so that the material strength or durability of the tunnel drainage system is attenuated beyond a specified range, which inevitably poses a threat to the long-term safe operation of the tunnel. Meanwhile, many acids are directly discharged into the environment along with a drainage system after the use, and biological enrichment can be caused, so that underground water is seriously polluted.
In view of the above, the present application provides a dredging detergent which comprises, by mass%, the corrosion inhibitor comprises 18-30% of compound organic acid (the specific dosage can be any value between 18%, 19%, 20%, 21%, 22%, 23%, 24%, 25%, 26%, 27%, 28%, 29%, 30% or 18-30%), 2-3% of penetrating agent (the specific dosage can be any value between 2%, 2.3%, 2.5%, 2.7%, 3% or 2-3%), 2-3% of corrosion inhibitor (the specific dosage can be any value between 2%, 2.3%, 2.5%, 2.7%, 3% or 2-3%), 64-78% of water (the specific dosage can be any value between 64%, 65%, 66%, 67%, 68%, 69%, 70%, 71%, 72%, 73%, 74%, 75%, 76%, 77%, 78% or 64-78%) and scale inhibitor; wherein the dosage of the scale inhibitor is 10 mg-20 mg (the specific dosage can be 10mg, 11mg, 12.5mg, 13.5mg, 15mg, 16mg, 17mg, 18.5mg, 19mg, 20mg or any value between 10 mg-20 mg) added into each liter of water.
In one embodiment, the osmotic agent comprises any one of JFC, JFC-1, JFC-2, and JFC-E of the class of nonionic surfactants. When the nonionic surfactants play a role in osmosis, the molecular structure of the nonionic surfactants is mainly hydrophilic polyoxyethylene ether with hydrophilic groups, and oxygen in a large number of ether bonds forms hydrogen bonds for hydrophilicity.
In another embodiment, the corrosion inhibitor comprises at least one of hexamethylenetetramine, thiourea and derivatives thereof, imidazoline quaternary ammonium salt, and octylphenol polyoxyethylene ether OP-10.
Specifically, the corrosion inhibitor comprises, by mass, 20% to 30% of hexamethylenetetramine (the specific amount may be any value between 20%, 21%, 22%, 23%, 24%, 25%, 26%, 27%, 28%, 29%, 30% or 20% to 30%), 60% to 70% of imidazoline quaternary ammonium salt (the specific amount may be any value between 60%, 61%, 62%, 63%, 64%, 65%, 66%, 67%, 68%, 69%, 70% or 60% to 70%), and 10% to 20% of octylphenol polyoxyethylene ether OP-10 (the specific amount may be any value between 10%, 11%, 12%, 13%, 14%, 15%, 16%, 17%, 18%, 19%, 20% or 10% to 20%).
Among them, hexamethylenetetramine, also called urotropine, is a traditional pickling inhibitor, is non-toxic and odorless, is often used as a corrosion inhibitor in pickling solutions of boilers, steam furnaces and the like, and can slow down the corrosion of metal materials. Thiourea and its derivatives are also commonly used for pickling corrosion inhibitors, and its derivatives include methylthiourea, ethylthiourea, phenylthiourea, tolylthiourea, n-propylthiourea, and the like. The imidazoline quaternary ammonium salt has the advantages of low toxicity, high stability and the like, and has wide application prospect in the aspect of being used as a corrosion inhibitor. The corrosion inhibition effect is mainly that a N atom on an imidazoline ring in a molecular structure can generate a coordination bond with a d-empty orbit on a metal surface, and a nonpolar alkyl chain can form a hydrophobic layer to prevent a corrosion medium from entering the metal surface. The imidazoline quaternary ammonium salt can be used as a corrosion inhibitor, and can be compounded with other corrosion inhibitors to further improve the corrosion inhibition effect. The octyl phenol polyoxyethylene ether OP-10 has good chemical stability and excellent characteristics of level dyeing, emulsification, wax prevention, corrosion inhibition, wetting and the like.

Aminotrimethylene phosphonic acid, also known as ATMP, has good chelating, low-limit inhibition and lattice distortion effects, and can chelate with various metal ions such as iron, copper, aluminum, zinc, calcium, magnesium and the like to form a stable complex, so that scale formation of salts in water can be prevented, and particularly calcium carbonate scale can be prevented. ATMP is easily dissolved in water, has good stability in water and is not easy to hydrolyze, and is often compounded with other organic acids into a water treatment agent to be used in a circulating water system to inhibit the formation of scale.
Polyaspartic Acid (PASP) and derivatives thereof are used as biodegradable green environment-friendly scale inhibitors, have an inhibiting effect on the deposition of inorganic and biological calcium carbonate, can be adsorbed on active sites of scale crystals in the growth process of the scale crystals, enable crystal lattices to be distorted to form aragonite and vaterite with rough surfaces, and influence the normal growth of the crystals, so that the formation of the scale is effectively prevented, the formation of calcium carbonate scale and the like can be inhibited at normal temperature by using a small dose, the texture of the calcium carbonate scale and the like is soft, and the calcium carbonate scale and the like can flow along with circulating water.
Specifically, the polyaspartic acid derivative includes any one of serine-graft-modified polyaspartic acid (ser-PASP), tryptophan-graft-modified polyaspartic acid (T-PASP), and threonine-urea-graft-modified Polyaspartic Acid (PASPTU).
Furthermore, the polyaspartic acid and derivatives thereof have an average molecular weight of 3000-5000 (specific values can be 3000, 3500, 4000, 4500, 5000 or any value between 3000-5000), and a viscosity of 0.055 dL/g-0.90 dL/g.
In another embodiment, the complex organic acid comprises any two or more of glycolic acid, hydroxypropionic acid, citric acid, oxalic acid, sulfamic acid, malic acid, and tartaric acid.
Wherein, the glycolic acid is colorless crystal, is soluble in water, has low corrosivity, is nonflammable, has low toxicity, strong biodegradability and high water solubility, is a hardly volatile organic compound, and has double properties of carboxylic acid and alcohol. Hydroxypropionic acid, i.e., lactic acid, has wide applications in food, medicine, cosmetics, agricultural storage, and the like, and can be used as a descaling product by utilizing the acidity thereof. Citric acid is relatively weak in acidity compared with inorganic acid, but is a relatively common organic acid cleaning agent because it is easily degraded by microorganisms and heat, does not affect the environment when used, and is excellent in safety. Oxalic acid, also called oxalic acid, is a binary weak acid and also has the function of removing scale. An aqueous solution of sulfamic acid has strong acidity equivalent to that of hydrochloric acid, sulfuric acid, etc., and is nonvolatile, odorless, and less toxic to the human body, and therefore, is often used in detergents for removing scale. Malic acid and tartaric acid are commonly used in the food and pharmaceutical industries, but are also one of the organic acids, and are also useful as detergents for scale removal.
The application also provides a preparation method of the dredging cleaning agent, which comprises the following steps: and adding the composite organic acid, the penetrating agent, the corrosion inhibitor and the scale inhibitor into water, and mixing to obtain the dredging cleaning agent.
In one embodiment, the mixing of the preparation method specifically comprises: adding the scale inhibitor into water, mixing, adding the corrosion inhibitor, uniformly mixing the scale inhibitor and the corrosion inhibitor, sequentially adding the composite organic acid and the penetrating agent, mixing and stirring until the solid powder is completely dissolved, wherein the solution has no precipitate.
