3.4.5 according to the actual needs of the construction of several requirements to achieve a flat hole-free, no batch of knife printing and sanding printing.
3.5-sided coating
3.5.1 Need to be kept clean before construction, if there is debris adhesion needs to be removed, the main agent and hardener proportionally mixed, fully stirred.
3.5.2 Using a rollerknife to evenly coat the material, the mixture takes 30 minutes to complete.
3.5.3 Construction junctions need to be handled.
3.5.4 construction completed 24h before the person, 72h before the pressure.
, the quality standard
4.1 ambient temperature is 25 degrees C, after construction 2-3d should reach the hard work, that is, the hardness reached about 80% of the completion of curing.
4.2 leveling is good,knife marks, large area interface is basically flat.
4.3 no floating hair flowers, uniform color, large area interface allows for a very non-obvious color difference.
4.4 is free of coarse impurities, but allows for minimal defects caused by dust falling in the air.
4.5 floor surface should be smooth, gloss should meet the design requirements (high gloss ≥90, light ≥70, half light 50 to 70), flat coating type for light, water for half light to no light.
4.6 orange peel, mortar non-slip surface effect should be obvious.

First, the introduction of gold sand flooring
Mainly composed of high-strength cement, inorgent wear-resistant bone, pigment powder (cement primary color no), additives and so on. The aggregate is sandy, with an average particle size of 1.5mm, accounting for about 60% of the total, and the glue is treated with high-label cement, which has a variety of colors to choose from, such as red, yellow, green and gray. Hardener bone composition is natural ore. Non-metallic bone that is not rusty and has a hardness of more than 8 degrees Mohs. In addition to natural ore materials, other cement, color materials and other weight does not exceed 25% of the total weight. This product is directly constructed on the concrete or cement mortar surface in the initial condensation stage, and after being flattened, a hard, hard-drying, dust-free and beautiful hardened floor is formed.
The essence of the gold sand floor is also cement products, it is a high-grade cement and different levels of quartz sand mixed products, it certainly has the characteristics of cement products: free state ca, Mg , from the pores non-stop predate the production of dust; By hydration cooperation with the loss of water at the end, resulting in a lot of capillary holes, and thus caused by non-dense, so its strength, wear resistance are greatly reduced, because the thickness of the diamond sand is generally 3 to 5 mm, very easy to fall off, if the time of the material is not well mastered. After the thickness of this layer is worn, the cement below begins to ash, so usually after one year of use of the floor, even if there is wax maintenance, it is inevitable scratching and wear.
II, the performance characteristics and scope of application
The color of the gold sand floor is optional, the surface is dense, not easy to dust, easy to clean, is a replacement for traditional industrial ground hydration grinding stone. Products are low cost-effective, cost-effective, long service life, wear resistance, impact resistance, pressure resistance performance is excellent. The construction is simple and is directly soused on the primary concrete, saving time and labor, eliminating the need for the construction of mortar surfaces, high wear resistance, reduced dusting, improved impact resistance, and improved oil and grease resistance.
The scope of application of the gold sand floor: because the performance of epoxy flooring and gold sand flooring is not the same, so in use must be based on the environment and needs to choose, epoxy flooring is applicable in no particularly frequent vehicle walking, no heavy objects often impact, no sharp hard objects often friction, no strong corrosive chemicals exist in a variety of industrial, civil, commercial flooring. And the sand wear-resistant flooring is suitable for all kinds of industrial, civil and commercial flooring that need to withstand frequent vehicle walking, frequent heavy impact, often sharp hardening friction, non-corrosive chemical presence, low requirements for cleanliness, and low aesthetic requirements.
, the construction process
bed concrete control→ the first stage of material scattering construction→ erasing→ lighting→ maintenance→ cutting seams, fillers.
1. Concrete substation to find a flat layer requires thickness of 30mm-50mmM or more, strength of C25 or more, minimum gel material content, site collapse degree of 75-100mm, the surface should be dense, flat, and no water.
2. When concrete first condenses, it is tested with finger pressure, leaving a 3-5MM imprint, and construction can begin.
3. Hand-cast ground hardening material, until its absorption of concrete moisture wet can be used to wipe the press to solidize, collect light.
4. Use a hand-smear knife to light up the mechanical construction area.
. During the construction process, do not throw water on the surface.
6. After the completion of the surface with special maintenance agents, with fine fog-like spray construction maintenance, do not cover with plastic cloth.
7. Cut the telescopic seam.
8. Use sealed coatings.
9. Sealing coatings: In some cases, there are high requirements for aesthetics and chemical corrosion resistance, at this time it is recommended to cover a layer with closed paint.
