Is it better to seal the curing agent lithium or sodium?

Lithium-based good. Sodium-based, sealant curing agent: The chemical reaction speed with concrete is slow, and sometimes produced after physical reaction.

swelling and the appearance of small cracks; There will even be local or large-scale serious resurgence of moisture.

The desired effect is not achieved.

Lithium-based sealing curing agent is a kind of main inorganic silicate and functional.

and other additives, fused to make an inorganic aqueous solution, a material that is the best for regenerating the ground. Environmentally friendly materials, odorless, non-toxic, non-flammable, no volatile compounds (VOCs). This agent can effectively change the constitution of the concrete floor, through.

Powerful penetration, with the chemical composition in the concrete to produce a secondary chemical reaction, in the multidimensional space to form one.

network structure, so as to improve the overall densification effect, to achieve a concrete floor as solid as marble, both.

It is dustproof, prevents moisture return, has high wear resistance, smooth surface, long-term mirror effect, does not run sand, and is easy to rectify.

and other economic values.

1) Lithium-based grease, especially the grease thickened with lithium 12-hydroxystearate, has only two intersection temperatures, the first intersection temperature (i.e., from pseudo-gel state to gel state) is generally above 170, and the second phase transition temperature (i.e., from gel state to sol state) is generally above 200, therefore, when the suitable mineral oil is selected, it can be used for a long time at 120 or short-term use to 150.

2) Lithium-based greases, especially those thickened with lithium 12-hydroxystearate, can be seen by electron microscopy that their soap fibers form double-stranded, tangled twisted bands, so they have good mechanical stability.

3) The adsorption heat of alkanes by 12-hydroxystearate and lithium stearate was determined by gas chromatography, and it was found that the binding strength of lithium 12-hydroxyapyarate and lithium stearate to the liquid phase on the surface of soap fibers and the binding strength to the liquid in the crystal lattice were larger, so the lithium-based grease had good colloidal stability.

4) The degree of hydrolysis of water in alkali metals is small, so lithium-based grease has good water resistance and can be used in wet and water-contact mechanical parts.

Definitely lithium is good.

Don't be fooled, many use sodium to fill lithium.

Lithium-based good welcome to communicate.

I heard that there is a good house in Guangdong! Lithium-based concrete sealing curing agent is worth convincing!

Hello, I'm glad to answer for you: 1. The hardness of lithium-based potatoes and concrete sealing curing agent is n times that of general concrete sealing curing agent, and sometimes it can even be distinguished by hand. Second, the gloss of the general concrete sealing curing agent is cloudy and dumb, and the ground made of lithium-based concrete sealing curing agent is clear and transparent, and the clearer the bottom, the better the lithium-based concrete sealing curing agent.

In addition, the gloss of lithium-based sealant curing agent is easy to improve, for example, it is not difficult to achieve a gloss of 100, but it is the limit of a general sealant to achieve 60. 3. The better the compactness, the better the ground compactness made by the concrete sealing curing agent, and the resistance to oil pollution is also very good. It can be detected by drip experiment, I hope mine is helpful to you.

Hello dear! I'm glad to answer for you. The difference between the composition of the curing agent lithium and nano A: Hello, <>

The main difference between nano and lithium is the composition of the additives contained in the hardener. The traditional concrete curing agent is mostly nanobase. In fact, the former is a treatment of the surface layer of the concrete floor, and the penetration depth is usually between 3 6mm, and the effect of hardening treatment will be better and better with the deepening of the penetration of the sealing curing agent. ”

Summary. Hello lithium curing agent and reactive cement-based curing agent are the same The main differences between lithium-based concrete sealing curing agent and general curing agent:

One is the hardness, the hardness of lithium-based concrete sealing curing agent is n times that of general concrete sealing curing agent, and this hardness can be clearly felt even when touched by hand. On the other hand, in terms of gloss, the gloss of the general concrete sealing curing agent is misty and dumb, while the ground made of lithium-based concrete sealing curing agent will be clear to the bottom; The clearer the bottom, the better this lithium-based sealing hardener is. In addition, the gloss of lithium-based sealing curing agent is easy to improve, for example, it is not difficult to achieve a gloss of 100, but it is quite difficult to achieve 60 of general sealing curing agent.

Thirdly, the better the concrete sealing curing agent, the better the compactness of the ground made, and the oil resistance is also very good. And the Nalut ultra-nano lithium-based concrete sealant curing agent we used is very good. I hope mine is helpful to you and I wish you a happy life.

Are lithium curing agents the same as reactive cementitious curing agents?

Hello, lithium curing agent and reactive cement-based curing agent are the same, the main difference between lithium-based concrete sealing curing agent and general curing chain ant: one is hardness, the hardness of lithium-based concrete sealing curing agent is n times that of general concrete sealing curing agent, and this hardness can be clearly felt even when touched by hand.

Water-based hardeners are hardeners that can be applied to a variety of epoxy resins and provide different hardening speeds. Low viscosity, low color, not easy to burn, easy to clean, easy to use. Especially under wet concrete conditions, it has good bonding force and wear resistance.

Concrete sealing curing agents are divided into nano, potassium-based, and lithium-based concrete sealing curing agents. The main difference between lithium-based concrete sealing curing agent and sodium-based and potassium-based concrete sealing curing agent is manifested in the following five aspects: First, lithium-based concrete sealing curing agent will not turn white. Second, the hardness of lithium-based concrete sealing curing agent is much higher.

Third, lithium-based concrete sealing curing agent has good gloss. Fourth, the compactness of lithium-based concrete sealing and curing agent is much better, so the anti-oil performance is good. Fifth, the construction is simple.

Sodium-based and potassium-based are easy to produce, while lithium-based concrete sealant curing agents are highly technical. At present, there are five main companies on the market that have done a good job of lithium-based concrete sealing and curing agents: one is Nalut, the second is Ansaffre Miaole's Lishi Bole, the third is Sealsource, the fourth is Shibei, and the fifth is Mekansor's Merith or Shuerlac.

Here we mainly mention the Nalut lithium-based concrete sealing curing agent, which is the world's first to use ultra-nano lithium-based technology!

In terms of the current domestic concrete sealing curing agent market, in addition to nano-scale silica products, the main curing agent products are mainly lithium-based concrete sealing curing agents and sodium-based concrete sealing curing agents. So, which concrete sealant curing agent is better?

Beijing Kaifu specializes in the production of floor curing materials, has rich industry experience, the following will be a detailed introduction for you, compare the difference between lithium and sodium in the curing agent.

Comparison of the reaction speed of the lithium sodium group of curing agents.

The reason why concrete sealant curing agents can make the ground hard is because through the associated chemical reaction, a miracle substance is produced - C-S-H gel. The faster the c-s-h gel solidifies and compacts, the smaller the penetration depth of the curing agent, and the penetration depth is insufficient, resulting in the limitation of the overall sealing performance of the concrete, thus affecting the waterproof and impermeable ability.

Returning to the periodic table, we can see that sodium and lithium are homogeneous, both belong to alkali metals, and the larger the number of nuclear charges, the stronger their metallicity, and the stronger the metallicity, the stronger the hydration of its higher oxides. The pH range of lithium-based curing agents is 11-12, and the pH range of sodium-based curing agents is 13-14.

Affected by the alkaline environment, the stronger the alkalinity, the faster the reaction rate, and the alkalinity of Na+ is significantly stronger than that of Li+, so the reaction speed mask has a faster survival rate. The reaction of Na+-based silicate is more violent, which will make the C-S-H gel dense the capillary pores on the concrete surface too quickly, and hinder the purity of the curing agent in the direction of depth. In terms of the reaction speed of concrete curing agent, "fast" does not seem to be something we want.

Comparison of the ratio of lithium sodium group of curing agent.

The molecular weight of Li+ or lithium silicate is smaller than that of sodium group, and from the ratio of Na+, Li+ and SiO32-, compared with the same amount of Na+, Li+ can bring in more SiO32- ions, and the amount of C-S-H generated is larger, and the strength of concrete is higher.

Comparison of the ability of curing agents to inhibit adverse reactions of lithium sodium ASR.

Comparing the hydrophilicity of the two generations of curing agent products, the sodium-based hydrophilicity is stronger, which is easier to absorb water from the air and concrete, and expands the system where Na+ is located, which in turn leads to cracks in the concrete.

The lithium base is relatively stable, has low hydrophilicity, does not absorb water, and does not expand even in a high humidity environment, thus fundamentally curbing the problem of cracks from the limbs.

The right one is the best, like the Deligu concrete sealing curing agent we have been using in construction, the effect is good.

Compared with ordinary concrete floor sealing curing agent, Sino has many advantages, one is hardness, the second is permeability, the third is gloss, the fourth is clarity, the fifth is the simplicity of construction, and the sixth is compactness and oil resistance. Specifically, the German Sino lithium-based concrete floor sealing curing agent can improve the hardness, strength, wear resistance and density of the concrete surface, thereby reducing the damage to the ground by heavy machinery; It can prevent plastic thermal shrinkage, cracking, curling, peeling and partitioning of concrete; Resistant to up to 98% of water and water vapor pressure and UV rays; It can prevent the penetration of water, oil, chemicals, and the growth of moss and mold.

What are the specific advantages of lithium-based concrete sealant curing agent, the following will be analyzed from multiple dimensions:

a.Performance.

Manufacturers usually position lithium-based concrete sealing curing agents as high-grade and medium-grade, which are significantly better than ordinary curing materials (such as sodium-based and potassium-based) in terms of performance, which we can see in the evaluation of hardness, wear resistance, sealing and other attributes.

b.Shine effect.

Lithium-based concrete sealing curing agent has a relatively good light effect, and with the use of concrete polishing liquid, we can construct a cured floor with mirror light sensitivity. At present, many new and old aggregate floors on the market have gradually phased out the old waxing process and replaced with concrete sealing and curing agents for crystal surface layering.

c.Weakly alkaline.

Compared with ordinary curing materials, lithium-based concrete sealant curing agent has weak alkali characteristics, which is more stable and has low hydrophilicity, which can effectively inhibit the adverse reaction (ASR) of alkali aggregates and the whitening of alkali return.

d.Green and environmentally friendly.

Lithium-based concrete sealant curing agents can achieve a zero-VOC environmental protection level, combine water-based safety, environmental protection and durability, and thanks to the high level of environmental performance, it can be used in home decoration without the slightest problem.

e.Silica sol is abundant.

Compared with basic materials such as sodium and potassium, lithium-based materials can bring in more silicate ions, the amount of hydrated calcium silicate (c-s-h) generated will be greater, and the concrete will be stronger and longer. In a sense, to create a cured floor of the same quality, the amount of material applied to the lithium-based concrete sealing curing agent material will be relatively small.
