The full name of antifreeze should be called antifreeze coolant, which means coolant with antifreeze function. Antifreeze can prevent the coolant from freezing and cracking the radiator and freezing the engine cylinder block or head during cold winter parking. Many people think that antifreeze is only used in winter, but in fact, antifreeze is used all year round. Antifreeze is a kind of coolant containing special additives. It is mainly used in liquid-cooled engine cooling systems. Antifreeze has excellent properties such as antifreeze in winter, antiboiling in summer, antiscale and anticorrosion all year round. At present, more than 95% of water-based antifreeze using ethylene glycol at home and abroad uses ethylene glycol. Compared with tap water, the most significant feature of ethylene glycol is antifreeze, while water cannot prevent freezing. Secondly, ethylene glycol has a high boiling point, low volatility, moderate viscosity, small change with temperature, and good thermal stability. Therefore, glycol-based antifreeze is an ideal coolant.

Neutralizers are substances that interact with acids (acid salts) and bases (basic salts) to adjust the pH of the medium. It has a great impact on emulsion polymerization, acetalization reaction, resin curing, latex storage, etc. Any organic or inorganic alkaline/acidic substance that can form a salt with a COOH or an OH group can be used as a neutralizing agent, but the neutralizing effects of different alkaline/acidic substances vary greatly. Commonly used neutralizing agents include sodium hydroxide, potassium hydroxide, sodium bicarbonate, sodium acetate, sodium pyrophosphate, sodium carbonate, ammonia, hydrochloric acid, phosphoric acid, formic acid, acetic acid, AMP-95, diethanolamine, triethanolamine, and aminoacetic acid. wait. In anionic water-based polyurethane emulsions, when potassium hydroxide is used as the neutralizing agent, the emulsion has a better appearance, is less likely to yellow during storage and high-temperature use, and has better water resistance of the emulsion coating. The degree of neutralization should be controlled at 90% to 100%, and the neutralization temperature should be 30 to 40°C.

Antistatic agents are a type of additive that are added to plastics or applied to the surface of molded products to reduce the accumulation of static electricity. Generally, according to different usage methods, antistatic agents can be divided into two categories: internally applied type and externally applied type. Internally applied antistatic agents are mainly used for plastics. Antistatic agents can also be divided into two categories: temporary and permanent according to their performance.

Metal deactivators are additives in gasoline, jet fuel, etc. Often used together with antioxidant and anti-adhesive agents. It is used to inhibit the catalytic effect of metals, especially copper, on oil oxidation, so as to give full play to the role of antioxidant anti-adhesive agents and reduce the dosage of antioxidant anti-adhesive agents. [1] Commonly used are the carbonyl condensates of amines, such as N, N′-disaliylidene-1,2-propanediamine. Metal passivators can react with metal ions to form chelates, leaving the metal in a passivated state that loses its oxidation-promoting effect. The added amount is about 0.0003-0.001% (weight).

Chemical substances or compounds that can prevent or slow down the corrosion of materials when present in the environment (medium) in appropriate concentrations and forms, so corrosion inhibitors can also be called corrosion inhibitors. Its dosage is very small (0.1% ~ 1%), but the effect is significant. This method of protecting metal is called corrosion inhibitor protection. Corrosion inhibitors are used in neutral media (boiler water, circulating cooling water), acidic media (hydrochloric acid to remove scale, acid leaching solutions for rust removal of plated parts before electroplating) and gaseous media (vapor phase corrosion inhibitors).

Desulfurizers generally refer to agents that remove free sulfur or sulfur compounds from fuels, raw materials or other materials; in the control and treatment of pollutants, they mainly refer to agents that can remove sulfur oxides (including SO2 and SO3) in exhaust gases. Various alkaline compounds can be used as desulfurizers. This mixed solution desulfurizer has surface activity and catalytic oxidation, which can effectively promote the direct reaction of SO2, accelerate the dissolution of CaCO3, promote the rapid oxidation of CaSO3 into CaSO4, strengthen the precipitation of CaSO4, reduce the liquid-gas ratio, reduce the calcium-sulfur ratio, and reduce moisture. of evaporation. When the SO2 concentration at the flue gas inlet increases and is higher than the design value, the PH value in the absorption tower reaction pool decreases, and when a larger Ca/S ratio is required, CaCO3 can be quickly dissolved without expanding the volume of the absorption tower reaction pool. Increase the concentration of calcium ions, keep the pH value of the slurry in the normal range, and have a certain buffering effect on the pH value. Extending the running time of the slurry in the working section and reducing the number of times of slurry mixing can significantly reduce the scaling of the equipment and make the scale layer thinner. After the machine is shut down, rinse it with water and the scale layer will fall off easily. It can disperse and mobilize the scaling of the desulfurization system, reduce the siltation of scaling, reduce the content of chloride ions in the slurry, and reduce the corrosion and scaling rates of various materials in the desulfurization equipment to varying degrees. Among them, the reduction of carbon steel At most, the corrosion and scaling rates can be reduced by 74% and 79% respectively, and PVC can be reduced by 48% and 55%. The addition of desulfurizer can inhibit scale, corrosion, and corrosion, reduce clogging, scaling, corrosion, and wear of the desulfurization nozzle, reduce scaling, corrosion, and wear of the slurry circulation pump and impeller, and reduce spare parts maintenance in the desulfurization system. and replacement. Broaden the selection of desulfurization materials and improve the reliability of the system. The slurry circulation pump and oxidation fan can be reduced and deactivated under different working conditions to improve desulfurization efficiency and reduce operating costs. It is suitable for changes in sulfur content in coal and is suitable for high-sulfur coal. In the application of flue gas desulfurization, it has broad marketing advantages and can produce considerable economic and social benefits.
