What is a cement sealant and what are the components of a liquid cement sealant curing agent?

Cement sealant, also known as cement penetrating sealing curing agent, is a simple colored or colorless liquid, which can chemically react with calcium and magnesium ions in concrete to form a wear-resistant and dust-proof dense entity.

Cement sealant In the case of reasonable use, the concrete becomes wear-resistant and resistant to chemical penetration, and by penetrating deeply into the concrete, the residue after the reaction forms a silicate condensate, effectively filling the concrete capillary and becoming a dense entity. In addition to hardening and wear-resistant, it is another new feature of dustproof and smoothing the surface of concrete, so that the function of cement sealant can be fully effective.

Extension of knowledge points:

Characteristics of cement sealants:

1. Wear-resistant: cement sealant can solidify various components in concrete into a hard entity, increasing hardness and compactness. After use and maturation, the wear resistance is increased to more than 6.

2. Hardening: After being treated with cement sealant, the Mohs hardness is 8, and the Mohs hardness is increased by 3Impermeability:

The floor penetrant effectively penetrates into the concrete, and reacts with it chemically, locks the pores inside, and has a permanent sealing effect on the concrete surface, which can effectively inhibit water, oil and other surface dirt from entering the concrete.

4. Environmental protection: cement sealant is a kind of concrete sealing, dustproof, wear-resistant hardener, colorless, non-toxic, can make concrete strong and dustproof, can prevent water, oil penetration, alkalization, weathering, etc.

5. Dustproof: The cement sealant reacts with the salt in the concrete to form a dust-free and dense whole on the surface of the concrete, which permanently avoids the precipitation of concrete dust from the surface voids.

6. Compressive strength: The compressive strength of the treated sample is stronger than that of the untreated sample. The compressive strength is more than 3 times higher.

7. Curing: The cement sealant can penetrate into the surface of the concrete to form an impermeable sealant that can reduce the loss of surface water to ensure full and uniform curing.

Dustproof, pressure-resistant, oil-proof, waterproof, easy to clean, can increase the strength of ordinary cement flooring by more than two times in a short time.

1. The film layer of floor sanding treatment agent can effectively prevent the penetration of pollutants such as acid, alkali, solvent, gasoline, etc., making the surface easier to wash and clean.

2. The film layer of the floor sanding treatment agent penetrates into the gaps of the material and can play a long-term sealing role.

3. It has a high anti-fouling and dust-removing effect and excellent water resistance.

4. Improve the brightness of the surface.

5. Reduce surface resistance and improve wear resistance.

The basic raw material for sealing and curing agents.

In terms of acidity and alkalinity, it can be divided into two categories, acidic and alkaline.

If you use acid to make hard, then this can be said not to be a technology, several simple materials, can directly sand cement, ordinary polishing cement is quite strong, grinding can appear higher gloss, the defect of this material is that whitening, construction needs a lot of water cleaning, short service life. However, the cost is moderate, and it is not suitable for the development of a company in terms of profit reputation. Acidic materials are two main components, one is a weak acid reacts with cement to speed up the curing of cement, one is a strong acid to increase the speed, and the other is a catalyst, a brightener and a grinding aid.

Alkaline, commonly used sodium-based raw materials, hardness is slow, this is a basic principle, we have no way to change. If a company can make the floor hard and highly scratch-resistant with alkaline, then it can be said that this technique is professional.

Alkaline basic materials, can make the floor dense enough, the hardness is slowly growing, this technology is immature, first of all, this material, poor water resistance, if washed with water, most of the material will be washed away by water, do a good floor, because of poor water and weather resistance, life is also limited. This floor hardness is never as good as it can be. In fact, the service life of alkaline materials is very long, and most of the imported materials are alkaline.

As a military-quality Deligu cement sealing and curing agent, its composition is alkaline.

The quality of the concrete sealing curing agent can be obtained by proofing a small piece of floor, and then testing some properties of the proofed floor, as follows:

First, test the hardness.

The ground that has been sealed with curing agent and the ground that has not been done are cut with a key or steel knife, and the curing agent is effective if the scratch is generally not injured or has a significant improvement. On the contrary, if there is no significant improvement, it is necessary to consider whether it is effective.

Second, test the tightness.

Because the tightness determines whether the concrete continues to be alkalized and weathered, dusted, anti-fouling and seepage-proof, and whether it is easy to clean. After the construction, the direct dripping water is tested on the surface, and the more round and full the water is into beads, the better the sealing, and the less easy to form beads, easy to disperse, and not full, it means that the sealing is poor.

Thirdly, the brightness and transparent crystalline layer are tested.

In the case of no polishing agent, the more crystals formed by the chemical reaction, the tighter, the more evenly it reflects the light, the more, and the brightness will be better with the eyes. Good materials have many crystals, and a thin transparent crystal layer can be seen after construction, while there is little or no bad one, so brightness and transparent crystal layer are also one of the indicators of the quality of the material.

Concrete sealing curing agent is a colorless, odorless, non-toxic water-based liquid sealing curing agent, through effective penetration (3-8mm), chemical reaction with concrete, to generate non-expansion and non-shrinkage of stable chemical product calcium hydrated silicate, filling the capillary pores in the concrete, making the whole concrete a dense and solid and dense whole, to achieve hardening, strengthening, anti-wear, dustproof, waterproof, anti-chemical erosion, anti-salt, anti-oil, safe and environmentally friendly solid sealing effect. It also increases the service life of the floor by up to 30 years.

** It depends on whether it is a new ground or an old ground, if it is an old ground, it also depends on the damage of the ground, as well as the type of concrete sealing curing agent, brand and manufacturer.

Acceptance criteria after the construction of concrete sealing curing agent:

First, the acceptance of tightness.

The tightness is mainly reflected in the resistance to external stains, water, oil and other contaminants. Normal concrete sealing hardener flooring can effectively prevent the ingress of contaminants, but not absolutely.

The floor after construction should be better than the original ground in terms of antifouling performance, including stain penetration time and infiltration capacity.

Second, the acceptance intensity.

The optimal strength of concrete sealing curing agent flooring can reach 8-9 degrees on the Mohs scale, but not all floors are accepted as acceptance criteria after construction.

Generally speaking, the strength of the floor after construction should be greatly improved compared with the original ground, and the minimum standard is that there will be no ash and sand, and there will be no scars when scratched with non-sharp metal objects.

3. Acceptance and dustproof.

Preventing dust generation is the minimum standard for concrete sealant floors, and this applies to all floors that have been subjected to concrete sealant hardeners.

Fourth, the acceptance of gloss.

To achieve a high gloss, such as a mirror effect, mechanical grinding is required. This is mainly determined by the requirements of the customer, and there is no uniform standard.

5. Acceptance of anti-skid performance.

Whether it is a high-gloss or matte concrete sealing curing agent floor, it can not be slipped, otherwise it is suspected of waxing during the construction process, unless Party A permits, otherwise it is a cut corners.

Concrete sealing curing agent is a water-based liquid penetrant, which plays a role by effectively penetrating into the ground 3-8mm and reacting with the ground to fill the pores of the ground, which can greatly enhance the strength, hardness, wear resistance, permeability resistance and corrosion resistance of the ground. Because of its strong performance, concrete sealing curing agent is widely used in large factories, logistics warehouses, production workshops, large supermarkets, exhibition centers, airports, underground garages, sports centers, hospitals and other places.

The outstanding aspects of concrete sealing curing agent are in terms of penetration, hardness, and gloss. The hardness of the floor made of Zhongsinuo lithium-based concrete sealing curing agent is harder than that of the general concrete sealing curing agent floor, and it can be felt intuitively by touching it. In terms of the service life of the finished product, the service life of Zhongsinuo lithium-based concrete sealing curing agent will be relatively high, and at the same time, because of the high hardness and strong sealing, the floor will be more wear-resistant, and the ability to resist oil pollution is also very prominent.

In terms of gloss, the luster of Sino lithium concrete sealing curing agent is very bright, with a marble-like luster, while ordinary concrete is a bit gray and misty, which belongs to the matte category.

There are six main functions of concrete sealing curing agent:

1. Permanently improve strength and hardness;

2. Permanent sealing and impermeability;

3. Permanent curing of concrete;

4. Permanent no dust;

5. Super binding ability;

6. Save a lot of repair and maintenance costs.

In addition, there are some subdivision characteristics such as fire resistance, anti-slip, etc., which can be adapted to the use needs of the corresponding places.

Concrete sealant curing agent can be a new floor treatment product that can seal and cure the floor. As a new generation of water-based products, Sino concrete sealing curing agent has colorless, odorless, non-toxic, non-flammable and other chemical properties. It can penetrate into the ground 3-5mm, and then have a series of complex chemical reactions with the free calcium and magnesium ions in the concrete, and then form a network structure, which blocks the pores in the concrete, and solidifies the various components in the concrete into a solid whole, so as to obtain a dust-free and dense overall floor, which avoids the precipitation of dust in the concrete ground and makes the ground no longer accumulate dust.

Reaction principle of concrete sealing curing agent:

The strength of concrete is mainly the silicic acid compound (c-s-h) generated by silicon and calcium in the cement composition of concrete under the action of hydration, and c-s-h is the substance that plays the main strength role in concrete. The inside of the concrete is still undergoing a slow c-s-h hydration reaction after the initial setting of the concrete, which cannot be completely carried out under natural conditions, there are always a large number of free calcium ions that do not react to form c-s-h, and there is still a lot of potential to be tapped for the improvement of hardness. The active silicate ions contained in the liquid hardener microreact with the free calcium ions in the concrete to form calcium silicate compounds (C-S-H), so that the calcium ions in the concrete can further participate in the reaction and improve the strength and hardness of the concrete more significantly.

Concrete sealing curing agent, also known as penetrating ground hardener, is an odorless, environmentally friendly water-based liquid. Because many cement concrete floors are not wear-resistant, pressure-resistant, not durable, and for a long time, the cement floor is easy to dust and sand, and this ground can not undertake overloaded forklifts, goods, etc., which is easy to cause ground deformation, cracking and other phenomena, and can not meet the condition requirements of the use environment. After the use of concrete sealing curing agent, the performance of the ground has been greatly improved, the sealing curing agent will seal the concrete into a three-dimensional three-pile structure, a closed chamber, a solid whole, fill the capillary pores of concrete, effectively inhibit the entry of external pollutants, thereby improving the hardness of concrete, prolonging the life of concrete.

There may be several misunderstandings in the concrete sealing curing agent floor, I hope you will pay more attention when choosing to avoid stepping on thunder.

Clause. First, the curing agent floor material is not only determined by the unit price of concrete sealing curing agent;

Clause. Second, the cost of cured floor materials is not only the cost of concrete sealing curing agent products;

Clause. Third, not just one concrete sealing curing agent product can solve all the sealing curing agent ground problems.

Clause. Fourth, the concrete sealing curing agent products belong to fine chemicals, which are composed of a variety of chemical materials in strict proportions, and their components are stable and not composed of a single component, so they can identify the quality of the concrete sealing curing agent floor not through the eyes and other senses.

Concrete sealant curing agent has the following five functions.

1. Sturdy and wear-resistant, durable.

Needless to say, epoxy flooring, as long as you are engaged in the flooring industry, everyone must be very clear. It is simply the conscience of the industry to use 1 year without peeling, and it is considered a normal level to use it for 3-5 months. The concrete sealing curing agent can change the chemical composition of the concrete surface, improve the ability of concrete to resist weathering and ultraviolet erosion, so as to greatly extend the service life of concrete.

Real concrete sealant curing agent flooring can promise 30 years of large-scale machinery walking without dust and sand, bright as new.

2. Safe and environmentally friendly, non-toxic and harmless.

Sealing curing agent floor is an inorganic material that reacts with concrete to improve the strength of concrete, non-toxic and harmless, without any harm to the human body and the environment, and epoxy floor coating will add a large number of volatile organic solvents in the production, and the volatile gas of the solvent will cause great harm to the human body once inhaled.

3. The strength and hardness have increased significantly.

Mohs hardness is a unified standard used in the industry to judge the hardness of the ground, and the concrete sealing and curing agent can increase the Mohs hardness of ordinary concrete floors to more than 7, while the hardness of epoxy floors is about 5. The results are clear: sealing hardener floors on the factory floor with large machinery vehicles in and out offers unmatched advantages.

4. The process is simple, efficient and convenient.

The epoxy floor construction process is complex, the base layer needs to be waterproof, and the use environment is high, so the epoxy follow-up construction can only be carried out about 28 days after the concrete floor construction is completed; The construction process of Zhongsinuo concrete sealing curing agent floor is simple, and the material construction can be carried out on the second day after the completion of the concrete floor, which greatly shortens the construction period, and the whole construction period is about 45 days shorter than that of epoxy floor.

5. Good weather resistance and simple maintenance.

Epoxy flooring has extremely high requirements for temperature, humidity, light, and floor cleanliness. In the workshop where there are vehicles walking, once the vehicle brakes or makes a sharp turn, the epoxy floor coating will be softened due to the short-term high temperature generated by sharp friction, and the dust on the vehicle tires will penetrate into the inside of the epoxy floor coating, causing the coating to be bruised and discolored, which is extremely difficult to repair. The sealing curing agent floor has almost no requirements for the use environment, and only simple maintenance is required in the later stage, and the ground becomes brighter and brighter the more it is used.
