Commercial PVC flooring
Rubber flooring is the dialect of Guangdong people on PVC flooring. PVC flooring was first transmitted from Hong Kong. Guangdong is the closest language to Hong Kong and has a common language. With the climate, PVC flooring was first recognized and popular in Guangdong. It also gave birth to a large number of powerful material suppliers and construction teams. The so-called 'rubber floor' refers to the floor made of polyvinyl chloride material. Specifically, polyvinyl chloride and its copolymer resin are used as main raw materials, and fillers, plasticizers, stabilizers, colorants and the like are added to the continuous continuous substrate, coated or calendered, extruded or extruded. Process production.
1, rubber floor - safety
The rubber floor absorbs shocks and relieves knee fatigue and provides a comfortable foot feel. Due to the suspended structure design of the rubber floor, it can reduce the load of the human body by nearly 40% compared with the solid wood floor and the laminate floor, and can cushion the impact foot comfortably.
2, rubber floor - environmental protection
The rubber floor is an environmentally friendly floor that is harmless to people and the environment. The surface UV treatment layer is added with natural silver design, so that the rubber floor has a double antibacterial structure. When other floors are produced, the glue is inevitably contained in a certain amount of formaldehyde, and the glue The formaldehyde content of the floor is 0.
3, rubber floor - dimensional stability
The base layer of the rubber floor is added with a glass fiber layer, which is bonded by a special treatment process. The dimensional stability of the product is excellent, and it is suitable for the surface of the thermal expansion and contraction, even if it is used on the floor with a large moisture floor. Deformation, can maintain the original state for a long time.
4, rubber floor - silencer
The rubber floor has good sound insulation and noise reduction effect, creating a peaceful indoor environment, reducing and alleviating the noise generated by the natural impact of indoor objects falling on the floor.
5, rubber floor - thermal conductivity
The rubber floor has excellent thermal conductivity and is suitable for use in geothermal heating floors. The rubber floor has excellent thermal insulation properties and can create a comfortable indoor environment.
6, rubber floor - wear resistance
The rubber floor has a special wear-resistant treatment layer and has a long service life. High-strength wear resistance guarantees the service life of the floor.
7, rubber floor - durability
The rubber floor has the ability to withstand impact and is not subject to damage or dent by external impact.

Defects of PVC floor: 1. High construction requirements. 2, afraid of cigarette burns. 3. Non-natural materials.
Basic requirements: cement floor, marble floor, tile floor, terrazzo floor, pressure plate
First of all, there is a corresponding requirement for the ground flatness, hardness, strength, humidity and environmental humidity of the construction site to be constructed.
1. Ground flatness: The flatness of the 2m ruler should be less than 2mm-3mm.
2. Hardness: The surface hardness of the base layer is not less than 1.2 MPa.
3, strength: not below the concrete strength standard C-20 requirements.
4. Humidity: The moisture content of the base layer is less than 3%.
Installation method: (1) movable type (2) hot melt fixed type (3) fully fixed type
(1) Construction process
1. Process links in the preparation stage before construction:
1.1 Requirements before plastic floor covering
1, the moisture protection of the base layer must be thorough.
2, cement leveling layer:
A. The ground level shall meet the requirements of the national construction code (ie: <±2mm). The ceiling project has been completed, including fire lighting.
The ground must be hard, free of grease, sand, etc., and there is no floor shelling, pitting cracks and so on.
Fill or level the uneven surface of the platform; and the ground must be very smooth and smooth.
B. Before the construction of the rubber floor, the cement screed must be thoroughly dried.
C. The indoor temperature and the ground temperature are preferably 15-22 °C. It is not recommended to work below 5 °C or above 30 °C. Relative air humidity should be maintained at 20-75%. The cement solidification maintenance period has passed two weeks, and the ground should not be wet and have accumulated water. The moisture content of the base layer should be less than 5%.
6, the strength of the screed is not lower than the concrete
Standard ≥ 20 requirements.
7, the surface hardness of the base layer is not less than 1.2 MPa.
8. Before handing over the site, the site must be cleaned in time (such as garbage generated due to interior decoration), and other types of work must be evacuated from the site.
D. The door, window and lock project have been completed.
Prevent the groundwater gas from rising and penetrate into the ground, which will affect the bonding fastness of the glue.
A, because the board is closely attached to the ground, if there is any unevenness on the ground, it will be directly reflected on the floor surface. If the floor cement is not marked enough, sanding or grease, it will affect the bonding degree of the glue and the quality of the paving, which will cause the floor to foam; if the floor has sand, shell or crack, the paved floor will be topped one by one. Bumps, white and broken after local stress.
B. If the floor is too moist, the floor and the floor cannot be tightly bonded together, and the glue will lose its effect.
Not only for A. avoiding wallpaper glue, paint dripping on the floor to stain the floor; and materials and installers' soles staining and scratching the floor
B. Avoid construction quality problems and construction progress that may be caused by cross-construction.
If the mechanical and electrical engineering of the underground has not been completed, the mechanical and electrical engineering contractors will pick up the paved floors, which will affect the quality of the entire project when carrying out their work.
Insufficient temperature will cause the glue to dry out and will not bond the floor to the floor.
Other types of work put dust and debris on the ground, soiling the glue and damaging the floor.
After completion, the doors and windows are closed and locked to prevent people from entering and leaving.
1.2 Floor cleaning:
When constructing the rubber floor material, no matter how excellent the construction technology is, the corresponding decision is not made according to the conditions of the construction site, which not only can not get good results, but also cause future problems.
※ Construction process points:
1. Finish the floor with a floor polisher of more than 1000 watts to remove contaminated, raised and loose plots and knock out the empty surface.
2. Clean the floor with an industrial vacuum cleaner of not less than 2000 watts.
3, the crack on the floor is repaired with interface treatment agent or rubber floor glue mixed with quartz sand
1.2 Self-leveling construction
l Construction process points:
A. Grassroots treatment
The surface layer of the ground prior to self-leveling cement should be smooth, dry, strong, free of dust and dirt.
Construction steps and points:
First use a special blade to remove the original gypsum, paint, cement lumps and other protrusions on the ground, use high-grade cement to mix the special glue pad to level the pits and cracks of the ground surface to achieve the ground leveling requirements; then use the grinding machine to the entire ground Grind it all the way to ensure that there are no protruding and loose ground on the ground; then the aired surface is naturally air-dried or heated to dry quickly so that the moisture content of the entire surface does not exceed 6%; then the floor and all corners are cleaned with a broom Use a level measuring instrument to combine the surface of the surface with a particularly high point of chalk, and then use a sander to finish the grinding at this high part, so that the thickness difference between the place and the side is not more than 2 mm; The vacuum cleaner will completely absorb the ground of the construction, and it is necessary to remove tiny particles from the ground.
B. Upper interface agent (base oil)
The purpose of the base oil is to separate the surface base from the self-leveling cement and have a certain degree of moisture-proof function. According to the requirements of different manufacturers, some water can be added to the base oil. The proportion of water can be adjusted according to the manufacturer's recommendations. . After adding water, be sure to stir it thoroughly. Then apply the bottom oil to the surface evenly according to the amount supplied by the manufacturer. The special dry floor can be used to apply the base oil twice. The amount of application and one time of painting Again, the interval is determined by the discoloration of the base oil.
The preparation work before mixing must be sufficient. It is best for a group of construction personnel to reserve multiple buckets, three of which are used for mixing, one for measuring water and one for water. Water buckets must be accurate, and the ratio of self-leveling water of each manufacturer is not the same. It should be strictly in accordance with the water ratio recommended by the manufacturer. The agitator must choose a high-powered agitator, and it can be adjusted. It can be placed on the low-speed gear at first, and then stirred for 2-3 minutes. The mixing head is preferably a self-leveling agitating head because the agitating head not only has rotational force. Moreover, there is shearing force, which can fully mix self-leveling cement, and there will be no self-leveling cement block left on the barrel wall. After mixing 4-6 barrels, the mixing bucket and mixing head should be cleaned to prevent self-leveling from condensing on the barrel wall and the mixing head. The diameter of the mixing head is selected according to the inner diameter of the barrel. In general, the inner diameter of the barrel is 2.5 times the diameter of the mixing head.
D. Self-leveling and defoaming
Self-leveling construction must be carried out continuously and any cross-construction is prohibited within 24 hours. After the self-leveling cement is mixed, the cement in the barrel should be poured into the construction site as soon as possible. If the ground traffic is too large, you can use the self-leveling raft.
