Description
The composite quick-acting ice and snow melting agent has obvious ice and snow melting effect, wide application range and simple and convenient use method, and meets the requirement of 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 of the composite quick-acting ice and snow fast melting agent
The composite quick-acting ice and snow melting agent and the snow melting agent used at present are both used for lowering the freezing point of water, whether solid or liquid. The ice melting and snow removing mechanism belongs to the chemical category and belongs to the technical field of compound salt. The composite quick-acting ice and snow fast melting agent utilizes the water absorption of the composite quick-acting ice and snow fast melting agent and a large amount of heat released during melting to cause dislocation of structural lattices in snow, so that ice and 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 principle of the composite quick-acting ice and snow melting agent for melting ice and snow. In the process of development, the composite quick-acting ice and snow fast melting agent not only focuses on the application range and effect of ice and snow melting, but also mainly solves the problems that the existing domestic snow 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. 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 them are inorganic strong oxidizers, such as chromate, molybdate, tungstate, vanadate, nitrite, borate, silicate, etc., which act with metal ions in the anode region of the metal surface to form oxide or hydroxide oxide film to cover the anode and form a protective film. 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 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. 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 3 mg/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. Therefore, the corrosion inhibitor is used scientifically and reasonably, and can effectively inhibit the corrosion of the composite quick-acting ice and snow fast melting agent to carbon steel.
In order to effectively solve the problem that the composite quick-acting ice and snow fast melting agent corrodes cement concrete, the results of practice and laboratory tests show that: the corrosion of the composite quick-acting ice and snow fast melting agent to cement concrete can be effectively solved only by strictly controlling or removing the content of sulfate in the composite quick-acting ice and snow fast melting agent.
The following table shows the degree of corrosion of the sulfate concentration in water on 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, formCan exacerbate the failure of cement concrete. Only strictly controlling or removing sulfate ions SO in the composite quick-acting ice and snow fast melting agent4 2—The corrosion of the composite quick-acting ice and snow fast melting agent to the 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 quick-acting ice and snow fast melting agent is 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 quick-acting ice and snow fast melting agent aims at solving the problem of damage to plants when in use. The research shows that: due to the long-term use of a large amount of the chlorine salt snow-melting agent, soil is hardened, the salt content of the soil is increased, and the trees grow ill 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 plant in the implementation place is detected, and the composite quick-acting ice and snow fast melting agent is used for melting ice and removing snow according to the principle that what is needed for plant growth is supplementedMeanwhile, the fertilizer is changed into a compound fertilizer and soil hardening is inhibited, so that the growth of plants such as flowers, grass and trees is promoted, and the ecological environment is protected. Nevertheless, the environmental damage of the chlorine salt snow-melting agent, especially the pollution of the ground water, is highly regarded. Therefore, when melting ice and removing snow in winter, the use of the chlorine salt snow melting agent needs to be controlled, and the relatively environment-friendly ice and snow melting agent is adopted. Potassium carbonate does not react with water and is dissolved. The potassium carbonate reacts with an acid stronger than carbonic acid to produce carbon dioxide. The potassium carbonate reacts with citric acid to produce potassium citrate (potassium hydrogen citrate, potassium dihydrogen citrate), carbon dioxide and water. Reaction formula for generating potassium citrate: 3K2CO3 + 2H3C6H5O7 = 2K3C6H5O7 +3H2O+3CO2 . Citric acid is a triprotic acid which cannot react completely if it is in excess or deficiency, producing an acid or base salt. Therefore, the technical key points of the method are scientifically and reasonably mastered, and after the potassium carbonate and the citric acid are subjected to neutralization reaction, the pH value is about 7 and is neutral. Realizes the compound quick-acting ice and snow fast melting agent which is relatively environment-friendly and takes potassium carbonate as a main raw material. Sodium gluconate can not chemically react with potassium formate, calcium formate, sodium formate, potassium acetate, sodium acetate, calcium chloride, sodium chloride and the like, but potassium, calcium, sodium and the like react with water and release heat to promote ice and snow to melt, so that the aims of melting ice and snow are fulfilled. The sodium gluconate is organically combined with the sodium gluconate, plays a good synergistic effect in the ice and snow melting process, accelerates the ice and snow melting, and has a good corrosion inhibition effect on carbon steel. The pH value is about 7, and the method is relatively friendly to the environment.
