1、Wear-resistant floor, cement floor, concrete floor why to use ChemTec ONE concrete sealant treatment?
The abrasion-resistant floor improves the surface hardness of the original concrete while reducing the dust, but in essence it is the product of mixing high-grade color cement with different grades of quartz sand, and in essence it is still a cement product, it certainly has the characteristics of a cement product: the Free State of Ca + Mg + ions from the pores, resulting in continuous precipitation of dust; as a result of hydration after the evaporation of excess water, resulting in the formation of many pores, and then caused non-compactness, so its strength, wear resistance in 28 days after the curing period to reach a greater value. And this value in the increasingly heavy use of forklifts, forklifts, steel wheels, under the rolling vehicle, this value is declining, so usually after six months of use of the floor, even if there is waxing maintenance, but also inevitably scratch and wear and tear, therefore, day-to-day wear and tear caused by floor defects. The use of ChemTec ONE, so that the pores become dense, dust precipitation, the dust below permanent closure, because of the dense relationship, so that its pores become dense, wear resistance and surface hardness increased by 2-3 times, resistant to any friction and therefore more hardened, wear-resistant and dust-free.
The epoxy is an acidic adhesive used to bond to the surface of the floor. As the concrete is alkaline, when there is moisture, more alkaline, so it is very easy to cause viscous failure and shelling. ASTMD3359 showed a 17% increase in the adhesion of ChemTec ONE-treated floors to epoxy, in part due to a chemical reaction between ChemTec ONE and the alkaline components in concrete, which caused the alkali to fold out and the surface to become neutral, chemTec ONE, on the other hand, compacts the concrete to a high-density substance that does not allow water molecules to pass through, thus preventing water capillaries from reaching the top and preventing epoxy shelling. At the same time, a solid structure itself can withstand crushing and thus increase the life of the epoxy. And because of the sealing effect, the new floor treated with ChemTec ONE can be painted or coated after 7 days, greatly shortening the construction period.
As a result of the atmospheric composition and ultraviolet, water, the chemical composition of the erosion of exposed concrete, usually 3 to 6 months after the start of weathering, dust, then sand, powder, flaky off. In a microbial environment, the pores will soon grow bacteria, and then corrosion of steel, leading to soft concrete necrosis. Due to the compactness of ChemTec ONE by chemical reaction, most of the chemical substances enter the concrete interior and the microorganisms can not survive. The anti-weathering experiment of ASTMG23 shows that 10 years of natural light, water mist and ultraviolet rays have no bad effect on it, it can prevent the weathering of concrete, so the life of concrete is prolonged.
2、CHEMTEC ONE concrete sealant and domestic production of penetrant, sealant what is the difference?
Different manufacturers have different designs for the formulation of hardeners for cement floors and concrete pavements, but they usually contain inorganic compound, the compound undergoes a complex series of chemical reactions with the calcium oxide contained in concrete. Chemtec ONE concrete sealant contains a special secret formula to make the treated ground more resistant to chemical corrosion and damage, and to make the polished surface look more beautiful. And domestic production of penetrant, sealant to solvent as the matrix, the formation of film-like sealing layer, often contains rosin and harmful solvents. ChemTec ONE concrete sealant, which contains water-soluble inorganic compound and complies with today's environmental, health and safety requirements, is effective in penetrating the pores in the lower layers of concrete, with the deepening of penetration, the concrete surface strengthening efficiency will become higher and higher, the depth of deepening is usually between 5-8mm.
Although domestic manufacturers of penetrants and sealants sometimes refer to their products as“Sealants”, in fact the liquid is a treatment of the surface of concrete, it is equivalent to adding a layer of organic protective layer such as film on the surface of concrete, instead of the protective layer formed by chemical reaction in the concrete. The disadvantage of using film on concrete is that it can easily be worn out in areas with high traffic flow. Not only does the fragile coating feel bad, but the unprotected concrete surface is also vulnerable to damage from chemicals and corrosion agents. ChemTec ONE concrete sealant not only protects the surface of the concrete, but also the depth of penetration of the concrete. So it will not be scratched, peeled off, will not be printed on the tire tracks, do not need to re-add protective film.
3、Does the CHEMTEC ONE have a shiny surface that causes slippage? Because people usually have this concept: the bright floor must be very slippery.
Under normal circumstances, the frequent use of traffic will wear, damage the concrete ground. Chemtec ONE treated concrete floors do not wear out from frequent use. This hardening effect, whether rough with a broom surface, or calendering surface can keep the original concrete surface roughness, uplift and depression of the state unchanged. So the CHEMTEC ONE will give you a nice gloss over time. The shiny effect does not mean that the ground will be very slippery. Before ChemTec ONE treatment, the same surface will be hardened, dustproof, and permanently shiny after ChemTec ONE treatment (except for the surface seal) .
Many experts (especially engineers) are concerned with the coefficient of friction. ASTM test results show that the test surface must be placed on the 50 pounds of new stone bottom device. Then the detector pulls the device until it moves. A dynamometer measures force in pounds sterling and requires the device to be moved across the test surface. The friction coefficient can be derived from the formulas derived from these data. The smaller the coefficient of friction, the more slippery the ground.
ASTM test report shows that the standard surface dry friction coefficient value is 71, wetland surface value is 47. The concrete using ChemTec ONE was 86 in the dry and 69 in the wet conditions. It is obvious that there is no slip from the standard surface under detection. From this you can see that the ground is not slippery with ChemTec ONE.
4、Can a lot of raw concrete be treated with ChemTec ONE?
Many concrete surfaces, especially parking lots and pavements, are formed primarily by hard-bristle brushes or corrugated rollers. Many industrial floors are polished with electric machines, and ChemTec ONE works well with any polishing method.
If the rough concrete floor of the parking lot is sealed and hardened and ChemTec ONE is used with low coverage, the usual 18 m2/gallon coverage should be reduced to 15 m2/gallon for rough ground. If the surface area is large and loose, the rough surface will have more and larger pores than the dense polished concrete. So more ChemTec ONE is needed to seal and Harden.
However, whether ChemTec ONE is used in smooth or rough concrete, its chemical properties are the same. When ChemTec ONE penetrates into concrete and reacts with it strongly, gel is formed in the pores of concrete, thus increasing the compactness of concrete. Rough floor needs more raw materials, as long as enough raw materials will be effective.
The CHEMTEC One is demonstrated by its performance in a zero square metre parking lot. ChemTec ONE has the same effect of hardening, dustproof and wear-resisting on rough floor as on industrial floor. The only difference is that a rough finish doesn't produce the same intense shine as a ChemTec ONE on an industrial floor.
5、Can New and old terrazzo floors be treated with ChemTec ONE?
The traditional terrazzo has the unique advantages of low cost, arbitrary color mixing and mosaic, convenient construction, etc. , however, the traditional construction technology of terrazzo floor after 3-5 years of use has become very rough, weathering, abrasion, stain spots, dim. New ground such as protection is not good in has not yet been delivered to use dirty, but also to daily hygiene and cleaning bring serious obstacles.
How to make the weathered and worn terrazzo restore its original beauty, the current commonly used method in China is to clean the stone surface of the dirt, hit a layer of wax. This method can delay the natural weathering and abrasion of the new terrazzo surface, but for the weathered and abrasion of the terrazzo surface, the effect is the same as a layer of varnish on the surface of decaying wood, simply can not reproduce the effect of bright as a mirror. And the wax film formed in this way is very poor durability, generally only to keep about a week to re-clean wax. Cleaning and waxing is the current cleaning companies can not deal with the customer's expedient method, can not treat the symptoms, not to mention the root cause.
The reason why cleaning and waxing is not a real stone floor treatment is that there is no real solution to the technical key terrazzo treatment. The reason why terrazzo is as bright as a mirror, crystal clear, is mainly because the surface of terrazzo after machining formed a layer of glassy film, this film not only has a mirror luster, and can transparently show the internal structure of stone levels that people observe patterns, beautiful sense of beauty here. To restore the beauty of weathered and worn terrazzo, the key is to re-form vitreous film on the Terrazzo surface.
The principle of treating terrazzo floor with ChemTec ONE is that the weathered and worn layer on the terrazzo surface is removed to expose the fresh layer, and then a new vitreous film is formed by CHEMTEC One during construction, so as to restore the natural terrazzo bright decorative effect. After treatment, the surface hardness of terrazzo changed from 4.0 to 8.0-9.0, becoming more wear-resistant. And after no longer need to wax, can maintain more than 20 years of smooth light.
6、Is the CHEMTEC ONE floor different from other traditional floors?
At present, there are many choices of common industrial ground, because different industries have different requirements for production conditions, so there is not an absolutely good building materials, common ground materials are:
一、Epoxy flooring
Epoxy floor technology refers to the cement floor has been good coating epoxy resin coating, coating thickness of 1 -5 mm, forming a sealed organic protective layer. As the epoxy is organic, this protective layer has good chemical properties such as water resistance, oil resistance, acid and alkali resistance, salt spray corrosion resistance, etc. , is widely used in modern industry, long-term floor materials, widely used in medicine, food (aseptic production) and electronics, chemical (anti-static) and other industries. But organic coatings have several Achilles' heel:
1、Hardness and wear resistance: organic materials in the physical properties can not be comparable to inorganic materials, hard resin Mohs hardness of 2-3. As heavy moving loads such as cars, forklifts and dollies are frequently used in production workshops, parking garages and manufacturing epoxy, the ground is often severely scratched, cause the phenomenon of shell, off.
2、Service life: organic materials are polymer, which means that in radiation, light, temperature and other normal conditions, polymer chain will break, which is often said that aging! Good epoxy can last for 5-8 years, while the average industrial epoxy floor lasts for about 3 years.
二、Wear-resistant floor
Hard floor technology refers to: in the use of cement or concrete casting process mixed with diamond or other aggregates, the whole from solidification. The thickness of hardened layer is about 3-10mm. Due to the extremely high hardness of aggregates such as emery, so the hardness of hard flooring Mohs 6-7, common substances in the basic nothing can scratch its surface, so hard flooring hard, wear-resistant, smooth and seamless, in addition to being used as industrial plant floor, but also can be used for warehouses, garages, squares and other ancillary facilities ground. However, the ground produced by this technique is made of bonded carborundum with cement as an adhesive, so it has the characteristics of a cement product-the surface is bound to form pores left over after a large amount of water evaporates, these micropores have two negative effects on the ground:
1、Diffuse reflection on the light, so that the gloss is greatly reduced, if not waxing maintenance, there is no good visual effect.
2、Absorption of sewage and dust, not conducive to creating a clean production environment, not suitable for pharmaceutical and other industries.
3、With the passage of time, cement products surface weathering phenomenon, dust, sand phenomenon, general service life in 5-8 years, short 2-3 years.
三、Terrazzo floor
Terrazzo is a kind of cement-based artificial stone, which is widely used as ground material in public buildings and workshops because of its low price, good overall performance and controllable shape and color. However, due to wear and stain infiltration and other reasons, its surface quickly weathering, stripping, pollution, loss of due architectural features. The main means of maintaining terrazzo floors is daily cleaning and waxing and polishing, which is complex and costly, resulting in rough and worn terrazzo surfaces that can only be used as low-end products, it is an obvious hazard to creating a clean work environment.
四、Concrete seal hardener hard floor
Concrete sealant curing agent is a kind of environment-friendly chemical building materials, it can make up the defects of cement products floor. Applied to concrete floor, cement floor, terrazzo floor, so that the surface of the formation of a 7-8mm protective layer, service life in more than 30 years.
The concrete sealant hardener floor has the following characteristics:
1、High brightness: up to 70 degree gloss units, exceeding epoxy, equivalent to marble.
2、High hardness: Mohs hardness of 8-9(Diamond Mohs hardness of 10) .
3、Anti-permeability: water and oil resistance, weak acid and alkali resistance, and flat seamless, easy to clean, easy maintenance.
4、Long Life: service life of more than 30 years, to provide 20 years of quality assurance. This guarantee is unattainable on other floors.
5、Wide Range: the old ground for renovation, which is epoxy floor and wear-resistant floor can not be compared.
