Antifreeze for hydraulic support It is used to prevent freezing of hydraulic equipment such as hydraulic supports, external injection single hydraulic props and other hydraulic equipment in severe cold seasons, such as ground storage, lifting well maintenance, and factory transportation.
▼Identification method of antifreeze liquid for hydraulic support: 1. Price: As far as the price is concerned, the reference freezing point -25℃ liquid price is below 5 yuan/kg, it will basically not be the real product; 2. Smell, all kinds of pungent and unpleasant odors must be fakes, the real ones do not have much odor; 3. Hand feeling: non-lubricating and volatile (note: it is strictly forbidden to taste it with your mouth! Antifreeze additives contain carcinogens) is easy to open fake antifreeze added with low boiling point alcohol; the hydraulic support antifreeze packaging barrel has a white mouth If the solid appears, it is heavier to lift by hand, feels very astringent, and has no special smell. It is a fake antifreeze processed with industrial salt or brine; 4. Turbidity: Regardless of the color of the product, the relevant transparency must be maintained. A turbid product is not a good product. 5. Looking at the fluidity, compared with pure water, a good antifreeze has a slightly higher viscosity. ▼Notes when using: 1. In order to ensure the freezing point of the antifreeze liquid of the hydraulic support, this product must be used directly with the original liquid, and shall not be diluted for use. 2. According to the local low temperature during use, it should not be lower than the minimum use temperature of this type of antifreeze, that is, it can be used directly within the range of not lower than -40℃. 3. When adding this product, ensure that the system is clean and does not contain incompatible liquids, and all remaining original liquids in the equipment should be drained. ▼Storage and daily maintenance: 1. The antifreeze fluid of the hydraulic support should be stored indoors to prevent sun and rain. The storage temperature should not be lower than -35℃, and it should not be mixed with other oils. 2. The shelf life of antifreeze fluid for hydraulic supports is 12 months (subject to the date of manufacture), and it can only be used after passing the inspection after the expiration date. 3. The antifreeze liquid used for hydraulic supports must use special containers and liquid dispensing tools, and keep the containers and tools clean to avoid mixing impurities and affecting the quality of the antifreeze liquid. Car antifreeze The full name should be called car antifreeze coolant, so that the car can continue to use it even at low temperatures in winter. Antifreeze coolant is also an indispensable heat dissipation medium for the operation of automobile engines. It is generally stored in a water tank and pumped to the engine water channel to circulate and cool the engine.
The role of car antifreeze 1. Antifreeze Antifreeze can prevent the coolant from freezing and cracking the radiator and freezing the engine cylinder block or cover when the vehicle is parked in the cold winter. 2. Cool down. The boiling point of high-boiling water is 100℃, and the boiling point of high-quality antifreeze coolant is usually above zero. 3. Anti-corrosion The anti-corrosion engine and its cooling system are made of metal, including copper, iron, aluminum, steel and solder. When these metals come into contact with water at high temperatures, they will corrode and rust over time. The antifreeze not only does not cause corrosion to the engine cooling system, but also has anti-corrosion and rust removal functions. 4. Anti-scaling The biggest headache for drivers when using water as a coolant is the problem of scale. Scale adheres to the metal surface of the water tank and water jacket, making the heat dissipation effect worse and worse, and it is also very difficult to remove. The high-quality antifreeze is made of distilled water and added with anti-scaling additives, which not only does not produce scale, but also has the function of descaling. Of course, if your water tank has a heavy scale, it is best to clean it thoroughly with water tank cleaner before adding antifreeze. How often does the car antifreeze change (how long does it take to change) Antifreeze is used not only in winter but throughout the year. In normal car maintenance projects, engine coolant also needs to be replaced. Generally, the high-quality antifreeze is replaced once a year, and the cars that are not used frequently can be replaced every two years or every 40,000 kilometers.
