Overview of Liquid Lithium Silicate
Lithium silicate, also known as lithium water glass, is a colorless to slightly yellow, odorless, transparent or translucent weakly alkaline liquid with a pH value of 11~12. The relative density and viscosity of the product varies with the product model, with a relative density between 1.16 and 1.20 (20°C). Liquid lithium silicate can be dissolved in water and alkaline solution, insoluble in alcohol and organic solvents, and acid action free gel. It has self-drying, solution water evaporation, can generate a dry film insoluble in water, with water irreversibility.

Performance of Liquid Lithium Silicate
Vanadium is a silver-gray metal with a melting point of 1890±10 °C, which is one of the rare metals with high melting point. Pure vanadium is hard, non-magnetic and ductile, but if it contains a small amount of impurities, especially nitrogen, oxygen, hydrogen, etc., its plasticity can be significantly reduced.

FAQ
Q1
What are the advantages of liquid lithium silicate in lithium batteries?
Answer: As the electrolyte of lithium batteries, liquid lithium silicate has the following advantages: First, it has high ionic conductivity, which can improve the charge and discharge performance of lithium batteries; second, liquid lithium silicate has a wide electrochemical window and High chemical stability can adapt to the needs of lithium batteries in different working environments; finally, liquid lithium silicate also has good wettability and compatibility with positive and negative electrode materials, which can improve the cycle life and performance of lithium batteries safety.
Q2
What should we pay attention to when using liquid lithium silicate
Answer: When using liquid lithium silicate, you need to pay attention to the following points: first, avoid contact with acids to avoid neutralization reactions that may affect the use effect; second, control the use temperature to avoid too high or too low temperatures It will have an impact on the performance of liquid lithium silicate; finally, pay attention to storage conditions, maintain a dry, clean, and sealed environment to prevent moisture absorption and contamination.
Q3
What are the applications of lithium silicate in concrete?
Answer: Lithium silicate can be used as a lithium concrete densifier. It can penetrate the concrete surface and react with free hydroxides in the concrete to form a silicate gel, thereby sealing and curing the concrete. This sealing and curing effect improves the strength, durability and wear resistance of concrete floors.
Lithium silicate can also be used as a hardener on concrete surfaces. Through a secondary chemical reaction with the free lime in the cement slurry, lithium silicate can harden the concrete base surface within a certain period of time, thereby enhancing the strength of the concrete floor.
Lithium silicate densifier is also effective in reducing concrete floor dust generated by regular traffic or low-quality construction. This dust not only affects the aesthetics of the floor, but may also cause harm to people and property. The hardening effect of lithium silicate can effectively lock in dust and make the floor tidier.
Q4
What should we pay attention to when using lithium silicate as a lithium silicate concrete densifier?
Answer: It is important to note that lithium silicate is not an ideal sealing curing agent for all concrete surfaces. Lithium silicate treatment may not be effective if the concrete surface is already contaminated or damaged. In this case, surface repair may be required before sealing and curing with lithium silicate. Additionally, when using lithium silicate to seal and cure concrete, be sure to follow the manufacturer's instructions to ensure optimal results.
Q5
What substances can liquid lithium silicate react with?
Answer: Liquid lithium silicate can react with acids to form a gel. In addition, it can react with substances with hydrophilic surfaces (such as glass, steel, aluminum and fibers, etc.) to form a film layer.
Q6
How safe is liquid lithium silicate?
Answer: Liquid lithium silicate itself is non-toxic and non-flammable, but care must be taken to avoid contact with acids during use to prevent accidents. In addition, personal protective measures should also be paid attention to during operation, such as wearing protective glasses, gloves, etc.
Q7
What is the difference between liquid lithium silicate, sodium silicate and potassium silicate?
Answer: The main difference between liquid lithium silicate, sodium silicate, and potassium silicate is that the radius of lithium ions is smaller, which makes liquid lithium silicate have some unique properties, such as good stability under high modulus, self-drying and generation Water-insoluble dry film, etc.
