Description
The composite ice-melting and snow-removing agent has the advantages of obvious ice-melting and snow-removing effect, wide application range, simple and convenient use method and environmental protection.
One, the technical field
Belongs to the chemical category and belongs to the technical field of compound salt.
Second, background Art
Understanding of the invention
The composite ice and snow melting agent and the snow melting agent used at present are both in a solid state or a liquid state and are used for reducing the freezing point of water. The ice and snow melting mechanism belongs to the chemical category and belongs to the technical field of compound salt. The composite ice and snow melting agent utilizes the water absorption of the composite ice and snow melting agent and a large amount of heat released during melting to cause dislocation of structural lattices in snow, so that the ice and the snow are melted. When the ice and snow melt, the heat is absorbed to reduce the ambient temperature, and the vapor pressure of the solution is smaller than that of the ice and snow, so that the ice and snow are promoted to melt continuously to form the solution in order to achieve a new balance, and the freezing point of water is reduced. Under the condition of low temperature, the repeated complex motion balance process is the working mechanism of the composite ice and snow melting agent for melting ice and melting snow. In the process of development, the compound ice-melting and snow-removing agent not only focuses on the application range and effect of ice melting and snow removing, but also mainly solves the problems that the existing domestic ice-melting agent corrodes metal and cement concrete and harms plant growth.
As is well known, the problem of corrosion of metals is mainly solved by using a corrosion inhibitor. The corrosion inhibition mechanism of the corrosion inhibitor is to form a metal protective film on the surface of metal contacted with water to isolate the metal from the water so as to achieve the purpose of corrosion inhibition. There are many kinds of corrosion inhibitors. Classifying according to chemical components: can be divided into inorganic corrosion inhibitor, organic corrosion inhibitor and polymer corrosion inhibitor. The inorganic corrosion inhibitor mainly comprises: chromate, nitrite, molybdate, tungstate, polyphosphate, zinc salt, etc.; the organic corrosion inhibitor mainly comprises: some heterocyclic compounds containing nitrogen oxide compounds such as phosphonate, phosphonic carboxylic acid, sulfenyl benzothiazole, benzotriazole, sulfonated lignin and the like; the polymer corrosion inhibitor mainly comprises: polyethylene, POCA, polyaspartic acid, and other oligomers. The category of the control site of the corrosion inhibitor on the electrochemical corrosion can be classified into an anodic corrosion inhibitor, a cathodic corrosion inhibitor and a mixed corrosion inhibitor. Anode type corrosion inhibitor: most of the inorganic strong oxidants include chromate, molybdate, tungstate, vanadate, nitrite, borate, silicate and the like, and the functions of the inorganic strong oxidants are that the inorganic strong oxidants react with metal ions in the metal surface anode area to generate oxide or hydroxide oxide films to form a protective film on the anode. This inhibits the dissolution of metal into water, the anodic reaction is controlled and the anode is passivated. Cathode type corrosion inhibitor: chemical agents that inhibit the electrochemical cathode reaction. Carbonates, phosphates and hydroxides of zinc and carbonates and phosphates of calcium are cathode type corrosion inhibitors. The cathode type corrosion inhibitor can react with the cathode region on the metal surface in water, the reaction product is deposited to form a film on the cathode, and the reaction of the cathode releasing electrons is blocked along with the thickening of the film. Mixed corrosion inhibitor: the organic corrosion inhibitors with surface activity, such as mercaptobenzothiazole, benzotriazole, hexadecylamine and the like, have two polar groups with opposite properties in molecules, can be adsorbed on a clean metal surface to form a monomolecular film, and can form a film on an anode and a film on a cathode. Prevent the diffusion of water and dissolved oxygen in water to the metal surface, and play a role in corrosion inhibition. The corrosion inhibitor is classified into an oxide film type corrosion inhibitor and a deposited film type corrosion inhibitor according to the type of a protective film formed of the corrosion inhibitor. Oxide film type corrosion inhibitor: chromate, nitrite, molybdate, tungstate, vanadate, orthophosphate, borate, etc. are all considered as the oxide film type corrosion inhibitors. Chromate and nitrite are strong oxidizers and can react with metal without the help of dissolved oxygen in water to form a compact oxide film on the surface of the metal in an anode region. Precipitation film type corrosion inhibitor: carbonates, phosphates and hydroxides of zinc, carbonates and phosphates of calcium are the most common precipitated film type corrosion inhibitors. The corrosion inhibition performance of the tungstate is that the corrosion inhibition rate of the single tungstate to the carbon steel in the seawater is increased along with the increase of the concentration of the tungstate, the corrosion inhibition rate is low when the concentration is low, and the carbon steel corrosion can be accelerated below 40 mg/L. When the concentrations of tungstate, citric acid, HEDP and zinc salt in the quaternary compound corrosion inhibitor are respectively 30, 40, 10 and 3mg/L, the corrosion inhibition rate on A3 steel exceeds 93 percent. The single tungstate and the environment-friendly corrosion inhibitor are both anode type corrosion inhibitors, iron oxide is used as a main component on the surface of A3 steel after the corrosion inhibitor is added, and tungsten and phosphorus also participate in the formation of insoluble precipitation films. The corrosion inhibitor is used scientifically and reasonably, and can effectively inhibit the corrosion of the composite ice-melting snow-removing agent to carbon steel.
In order to effectively solve the problem that the composite ice melting and snow removing agent corrodes cement concrete, the results of practices and laboratory tests show that: the corrosion of the composite ice-melting and snow-removing agent to cement concrete can be effectively solved only by strictly controlling or removing the content of sulfate in the composite ice-melting and snow-removing agent.
The following table represents sulfate concentration in water versus: portland cement, pozzolana portland cement, fly ash portland cement, portland slag cement, composite portland cement, and portland cement.
The following table shows the effect of sulfate concentration in water on the corrosivity of portland and portland cements:
| SO4 2—mg/L | degree of corrosion |
| ﹤300 | Low in micro |
| 300-600 | Is low in |
| 600-1500 | Medium and high grade |
| 1500-5000 | Severe severity of disease |
| ﹥5000 | Is very serious |
As can be seen from the table: only sulfate ions SO in water4 2—When the concentration of the carbon black is less than 300 mg/L, the corrosion is low. It should be noted that: sulfate corrosion products, because of their low solubility, produce precipitation products that cause stresses that can exacerbate the failure of cement concrete. Only strictly controlling or removing composite ice meltingSulfate ion SO in snow removing agent4 2—The corrosion of the composite ice melting and snow removing agent to cement concrete can be effectively solved. The above table does not mention the introduction that the chloride ions transform the reinforcing steel bars in the concrete from the passive state to the active state to form corrosion products to expand, so that the cement concrete cracks and peels off, thereby losing the mechanical properties and causing damage. But through experimental analysis: the chloride ions are required to change the steel bar from the passivated state to the activated state until a certain critical value is reached. The academics consider that: CL-/OH-≧ 0.61, corresponding to: 0.3-0.6 kg of CL-/m3The size of (2). When solving the problems, firstly, the percentage content of chloride ions in the composite ice-melting and snow-removing agent needs to be controlled; secondly, the content of sulfate is reduced as much as possible, and the corrosion problem of cement concrete and steel bars can be effectively solved only by simultaneously meeting the two requirements.
The composite ice-melting and snow-removing agent aims at solving the problem of damage to plants when the composite ice-melting and snow-removing agent is used. The research shows that: due to the long-term use of a large amount of the chlorine salt snow-melting agent, soil hardening and salt content increase can be caused, and the trees can grow pathologically and even die. The control indexes of the plant on the chloride are as follows: when the ratio of the salt content of the soil to the weight of the soil is less than 0.15%, the plants grow normally; when the ratio is 0.15% -0.25%, the plants are slightly injured; severe damage occurs in 0.25% -0.4% of plants; the plants are deeply damaged when the percentage of the plants is 0.4 to 0.6 percent; above 0.6%, the plant will die. As known, 16 kinds of nutrient elements are supplied to plant growth, namely nitrogen, phosphorus, potassium, sulfur, calcium, magnesium, carbon, hydrogen, oxygen, boron, iron, molybdenum, copper, zinc, manganese and chlorine. The nitrogen, the phosphorus and the potassium are major elements, and the balance are medium and trace elements, although the required amount of the elements by the plant is small, the elements play an equally important role in the growth and development of the plant and cannot be mutually replaced. Therefore, the plants in the implementation area are detected, and the composite ice-melting and snow-removing agent is changed into the compound fertilizer while melting ice and removing snow according to the principle of supplementing what is lacking in the growth of the plants, so that the growth of plants such as flowers, grass and trees is promoted, and the ecological environment is protected.
