    Currently wear-resistant flooring commonly used material characteristics
    Epoxy flooring has beautiful, dust-proof, chemical corrosion resistance and other characteristics, is widely used, but raw materials and construction costs are high, poor hardness, easy to be damaged by vehicle machinery and equipment, generally 3 to 5 years need maintenance, high comprehensive cost, and poor weather resistance, not suitable for coating in the underground humid environment, also not suitable for outdoor applications. King Kong sand wear-resistant flooring is based on gold sand or quartz sand and high-label cement as the main body of wear-resistant floor, with low materials and construction costs, can withstand a variety of vehicles, machinery and equipment wear and other advantages, but its own strong alkalinity and porousness caused it to be oil-resistant substances (will leave spots), can not resist chemical corrosion, easy to be acid, alkali corrosion, clean brightness and aesthetics is not high, in the harsh environment will not always sand.

    Sealing curing agent wear-resistant flooring operation process
    concrete sealing curing agent wear-resistant floor construction operation process is: ground concrete pouring - leveling - scattering wear-resistant bone and polishing - water conservation 7 to 14 days - ground shrink seam cutting - concrete sealing curing agent immersion - floor maintenance.
    Sealing curing agent construction points
    1 material requirements
    different sealing curing agents on the construction temperature, time, dosage, operation, etc. have different requirements, before construction must be familiar with the sealing curing agent product instructions, and in accordance with the requirements of the instructions for operation. All types of sealing curing agents should have non-toxic, tasteless, simple to use, penetration, sealing, improve concrete performance and other quality requirements.
    2 Concrete base requirements
    first, concrete grass should be level. Because the sealing curing agent is a liquid, does not have the function of finding flat, therefore, the flatness of the concrete base is the flatness of the wear-resistant floor after completion. Moreover, the unevenness of the grass-roots easily leads to sealing curing agent difficult to be clothed on the ground surface, after painting the sealing curing agent, it is easy to appear a large number of "small puddles" in the ground recess, and the ground protruding can not effectively "absorb" the sealing curing agent. The grass-roots flatness should reach the 4mm level.
    , grass-roots clean-up should be carried out. Cement slag, dust, oil, garbage and other comprehensive clean-up on the concrete base, in order to open the grass surface with the capillary holes, in order to help the concrete sealing curing agent more and better seep into the ground; Seal curing agent construction can be carried out after 80% dry (no clear water) on the ground.
    third, grass-roots conservation should be strengthened. Improper grass-roots conservation is prone to cracking and is susceptible to contamination. Should be on the ground grass-roots construction after about 5 hours, that is, began sprinkler conservation, water conservation should last more than 7 days, to ensure that the concrete surface is in a continuous wet state. After the completion of the grass-roots construction, except for water conservation agent cutting seam personnel, the rest of the personnel may not move back and forth. Special attention should be paid to the use of clean water conservation, dirty water or water containing impurities easy to pollute the grass, impurities embedded in the base capillary holes will lead to sealing curing agent can not penetrate.
    , the strength of the grass-roots concrete should reach C25, the old ground should be fully polished first, and the painted ground should be completely polished and scraped.
    3 Sealing Curing Agent Operation
    first, soak the entire base surface with a sealing curing agent. The sealing curing agent is evenly sprayed on the base surface, and the spraying amount should be increased at the base bulge or at a faster penetration to ensure that the entire base surface is moistened by the sealing curing agent for 30 minutes.
    After 30 to 40 minutes, most of the sealing curing agent has been absorbed by the concrete base surface, in order to allow the remaining sealing curing agent to be fully absorbed into the surface, constantly sweep away from the low-altitude and puddles or wipe away any excess material to other bulges; When the feet are slippery and thickened, rinse the entire surface thoroughly with water and wipe them completely to remove any residue from the sealing curing agent.
    construction time is 1 to 3 hours, after the construction of the dry ground can walk normally. The ground should be kept clean for 48 hours and no water or grease should be lowered to the ground.
    , attention should be paid to the sealing curing agent wear-resistant floor maintenance. Sealing curing agents and concrete will continue to chemical reactions, and one to two times a week with the washing machine mechanical cleaning will accelerate their reaction, so that the surface gloss as early as possible, and can be as early as possible road impermeable effect. In addition, because the acidic solution will corrode the ground, so that the surface of the floor dim, therefore, must be used weak alkaline detergent to clean the ground, and timely cleaning of the surface of the floor dirty;
    4 Wear-resistant flooring performance verification
    due to chemical reasons, in dust, hardening, wear resistance and other aspects within a few hours after the completion of construction began to appear, but its luster, sealing, impermeability with the deepening of the chemical reaction took several months to gradually appear. According to the engineering characteristics and actual situation, the following easy-to-operate and feasible detection methods are used for performance verification.
    4.1 Check hardness
    seven days after the completion of the concrete seal curing agent construction, 28 days with copper and iron sheet and plane and sharp angle two ways of friction of the ground, compared with the untreated ground, the hardness of the treated ground significantly increased, basically no scratches, untreated ground with obvious scratches, and accompanied by dust generation;
    4.2 Dustless detection
    visual inspection, wipe with paper towels, no dust on the treated ground,
    4.3 intensity detection
    28 days later with a rebounder to detect
    4.4 surface quality
    no significant color difference, smooth surface, smooth, no waxing.
