“PVC floor” refers to the floor made of polyvinyl chloride materials. Specifically, it is made of polyvinyl chloride and its copolymer resin as the main raw materials, with fillers, plasticizers, stabilizers, colorants and other auxiliary materials added, and is produced on a sheet-like continuous substrate through a coating process or a calendering, extrusion or extrusion process.
Clean room PVC floor is a high-quality floor made of PVC material and wear-resistant sand and stone. It is light, wear-resistant, beautiful, and anti-bacterial. It is divided into homogeneous core-penetrating, composite, sports, anti-slip and anti-static and conductive series. It has a wide range of uses and specifications include blocks and rolls. It is a new type of building material and one of the modern environmentally friendly products. The scope of application: properly treated old marble surface, terrazzo surface, smooth tile surface, overhead wooden board surface, cement poured floor, and specific metal surface paving. It is widely used in hospitals, office buildings, industrial and mining enterprises, schools, hotels and other places.
ultra-light and ultra-thin, super wear-resistant, high elasticity and super resistance, super anti-slip, waterproof and moisture-proof, sound-absorbing and noise-proof, antibacterial performance, quick installation and construction.
In the early, middle and late stages of installation, the temperature of the floor material installation area should be maintained at at least 18℃ for 48 hours. Please note that low temperature of the base has a considerable impact on the opening time of the adhesive.

The base of the PVC floor should be flat, dry, solid, free of dust and dirt, etc. The construction steps are as follows
1. Scrape off the original paint, cement hardening and other protrusions on the ground, fill the potholes, and meet the ground flatness requirements.
2. Use a grinder to grind the undulating ground into a surface thickness difference of no more than 2.0 mm within two consecutive square meters.
3. Let the flattened ground dry naturally or use heating to quickly dry it, so that the moisture content of the entire ground does not exceed 6%.
4. Use a broom or dust mop to clean the ground and every corner.
5. Use a large vacuum cleaner to completely vacuum the construction ground and the ground where the material is cut several times, and be sure to remove the tiny particles on the ground. At this time, you should change to clean shoes to operate.
1. Before laying the floor, the PVC floor should be laid out in the construction site at an ambient temperature above 18℃ for at least 24 hours to remove the stress in the material.
2. First, the construction tools need to be prepared: check the operation and power consumption of the main mechanical equipment, and arrange the construction power supply and water source. Imported tools should not be mixed with other electric tools A wiring board must be equipped with a voltage stabilizer and power protection device. Avoid excessive current causing the machine to not operate normally and delay the construction period. Check the use of various types of manual tools such as: the use of floor material cutting knives, slotting knives, seam cutters, scraping boards and other tools, whether the surface of the glue roller is clean and smooth, and replace its wear parts in an emergency if it does not meet the use standards to ensure the construction quality.
3. Apply the interface agent; after the self-leveling construction is completed, there may still be tiny particles and floating dust on the surface. In these cases, a grinder is required for further fine leveling. After fine grinding, some dust will remain on the ground and is difficult to remove. It is necessary to apply the water-based interface agent again. The purpose is to close the tiny pores and dust on the self-leveling surface, make the surface smooth, improve the bonding effect of the adhesive, and avoid bulging and debonding of the floor after the construction is completed.
4. Check the construction environment: Before laying the floor, the temperature of the construction site should be checked. The indoor temperature of the construction room should not be less than 18°C, and the relative humidity of the air should not be greater than 75%. The work area should be fully ventilated, and pollutants should not be allowed to enter other parts of the building.
5. Place the material: Before construction, the PVC roll floor must be unfolded and laid flat on the flat ground. After it is restored to flatness and loses material stress, it is placed in the room where the adhesive is to be applied. Reasonably arrange the cutting area to ensure that the cutting area is dust-free and sand-free. Special transportation tools should be used for transporting and handling coils. The damaged floor produced during transportation and handling should be cut off with a plastic trimmer before cutting and cannot be used.
According to the laying design plan, the size error is measured by combining field measurements, the defense points are determined according to the laying design plan, and the outline of the flooring is popped out with an ink box. Cut the material according to the outline, properly arrange the layout of the welding line and the parquet, and minimize material loss. Operation points: Cutting materials must be done by a dedicated person: If the floor has directional patterns, the consistency of its direction must be paid attention to at all times; Each time cutting, accurate data must be obtained from the site; Each time cutting, pay attention to the 2-3 cm margin between the materials.
Use adhesives to evenly and firmly bond the PVC floor to the floor, and process the overlapping parts of the floor into a splicing with a slight gap, and the gap should be within 0.2-0.5mm.
The weld should be straight, smooth, without cracks, burnt spots, or broken welds, and should blend in with the entire floor in color and feel. Operation points: Use a grooving tool to open a 2.5mm wide U-shaped groove between two floors, which is equivalent to three-quarters of the floor thickness; the welding line should be a straight line; use a welding gun to remove the glue and dust in the groove; adjust the welding machine to a suitable temperature, wait for the hot air to stabilize, insert the welding line into the welding nozzle, and weld at a constant force and uniform speed; half an hour after welding is completed, use a butterfly blade combined with a shovel to remove the excess part of the welding line from the ground twice, one rough shovel and one fine shovel.
Clean the adhesives, dust, shoe prints, etc. brought by the construction process. In order to extend the service life of the floor and facilitate future maintenance, the floor should be waxed with base wax and surface wax. Operation specifications: Thoroughly sweep and vacuum, wet mop with neutral detergent or clean the entire floor with a machine at a low speed. Do not use a large amount of water to clean at least four to five days after construction to prevent water from penetrating and affecting the joints and glue adhesion. Use a 3M red cleaning pad to scrub the floor and then use a large water absorber to remove the residue, thoroughly clean and dry. Use a waxing machine with a speed of 175 to 1500 rpm and 3M super hard wax to evenly apply it on the floor. Finally, use a high-speed polishing machine to polish the wax water applied on the floor until the ideal gloss is obtained.
