Answer: Yes. Very suitable for floor heating, heat dissipation faster than other floor materials.
2. Can it be laid directly on the floor tiles?
3. Can it be laid directly on the concrete floor?
Answer: Yes, as long as there is no sand on the concrete floor, it can be paved directly if the flatness is good.
4. Does the ground have to self-level before installation? Is it generally impossible to level?
Answer: The basic requirements of spc environmental protection floor are not too high. Generally, leveling can be done as long as possible. The fall within two square meters cannot be greater than 2-3mm.
5. Do you need moisture-proof pads? Use skirting for finishing? Should I use adhesive?
A: In principle, no moisture-proof pad is needed. The back of the spc floor has a sound-absorbing film. It is recommended to use baseboards for the edge.
6. Will water bulge, warp, shrink or deform?
7. Does the floor smell?
8. Will there be any water leakage at the handover of the lock?
A: There is no problem in normal care. The bathroom can be easily handled with glass glue on the seam.
9. Will there be indentation when the furniture is put on for a long time?
Answer: No, there is no problem with the compression test carrying 2 tons.
10. How do you feel about your feet? Will it be particularly hard?
Answer: The flexibility is good, not cold, and the foot feel is better than the general ground materials.
11. How about the sound insulation effect?
Answer: There is a sound insulation layer at the bottom, which is very good in sound absorption and sound insulation.
12. How to measure the number of square meters needed in the room?
Answer: The space needed for pavement is long X wide, and the net area plus 2-3% loss can be obtained.
13. What is the size and thickness of each piece of SPC floor?
Answer: 184mm * 1220mm * 5mm
14. Can the size be customized?
Answer: Fixed size, cannot be customized.
15. Can the kitchen, bathroom and balcony be used?
Answer: Yes. Waterproof, anti-stain and oil stain, easy to handle.
16. Can SPC floor be herringbone?
ground detection, use temperature and humidity meter to detect temperature and humidity, indoor temperature and surface temperature should be 15 ℃, should not be constructed below 5 ℃ and above 30 ℃. The relative air humidity suitable for construction should be between 20% -75%. Use the moisture content tester to detect the moisture content of the base layer. The moisture content of the base layer should be less than 3%. The strength of the base should not be lower than the requirement of concrete strength C-20, otherwise a suitable self-leveling should be used to strengthen the strength. The test result with the hardness tester should be that the surface hardness of the base layer is not less than 1.2 MPa. For the construction of stone-plastic floor materials, the unevenness of the base should be within 2 meters of the straightedge, and the height difference should be less than 2 mm, otherwise a suitable self-leveling should be used for leveling.
floor pretreatment, using a floor grinding machine with more than 1000 watts and appropriate grinding discs to polish the floor as a whole, removing paint, glue and other residues, raised and loose plots The plots with empty drums must also be removed. Use an industrial vacuum cleaner of not less than 2000 watts to clean the floor. For cracks on the floor, it can be repaired by using quartz sand on the surface of stainless steel reinforcement and polyurethane waterproof adhesive.
self-leveling construction-priming. Absorbing base layers such as concrete and cement mortar screed should be diluted with water at a ratio of 1: 1 using a multi-purpose interface treatment agent and then sealed and primed. For non-absorbent substrates such as tiles, terrazzo, marble, etc., it is recommended to use a dense interface treatment agent for primer. If the moisture content of the base layer is too high (> 3%) and it needs to be constructed immediately, the epoxy interface treatment agent can be used for primer treatment, but the premise is that the moisture content of the base layer should not be greater than 8%. The construction of the interface treatment agent should be uniform without obvious liquid accumulation. After the surface of the interface treatment agent is air-dried, the next step of self-leveling construction can be carried out.
4. The fourth step of SPC floor installation:
self-leveling construction-mixing, pour a packet of self-leveling into the mixing bucket filled with clean water according to the specified water-cement ratio, and stir while pouring. In order to ensure uniform self-leveling stirring, a high-power, low-speed electric drill with a special stirrer must be used for stirring. Stir until a homogeneous slurry without lumps, let it sit and cook for about 3 minutes, then stir briefly again. The amount of water added should strictly follow the water-cement ratio (please refer to the corresponding self-leveling instructions). Too little water will affect mobility. Too much will reduce the strength after curing.
5. The fifth step of SPC floor installation:
self-leveling construction-laying, pour the mixed self-leveling slurry on the construction floor, it will flow and level the ground by itself, if the design thickness is ≤ mm, you need to use a special The tooth scraper is slightly scraped. After that, the construction personnel should put on special spiked shoes and enter the construction ground. Use a special self-leveling deflation roller to gently roll on the self-leveling surface to release the air mixed in to avoid air bubbles and interface height differences. After the construction is completed, please close the site immediately. It is forbidden to walk within 5 hours, avoid heavy objects within 10 hours, and lay stone-plastic floors after 24 hours. In winter construction, the floor should be laid after 48 hours of self-leveling construction. If you need to polish and polish the self-leveling, it should be carried out after 12 o'clock.
1.The board is yellow. The extrusion temperature is too high or the stability is insufficient. The solution is to reduce the processing temperature. If the improvement does not improve, the formulation can be adjusted. The stabilizer and lubricant can be added appropriately. It can be changed one by one. It is easy to find out the problem quickly and solve the problem at the fastest speed.
2.The plate is yellow in the middle. The main reason is that the temperature of the core of the barrel is high and the temperature of the mold is also related to the amount of lubricant. Once again, it has a certain relationship with the white foaming agent.
3.The board is curved. Uneven material flow or inadequate cooling, the factors causing uneven material flow are generally large traction fluctuations or unbalanced internal and external lubrication in the formula. The factors of the machine are easy to eliminate. Formula adjustment generally adjusts internal lubrication under the premise of as little external lubrication as possible Very good results, while ensuring that cooling is evenly in place
4.Cells or layers of bubbles appear on the cross section. The reason can be attributed to one point, that is, the melt strength is not enough, the reasons for the insufficient melt strength are: 1. excessive foaming agent or insufficient foaming regulator or inconsistent ratio of the two, or quality problems of foaming regulator 2. plasticizing Bad, low processing temperature or excessive lubrication.
5.Uneven thickness of the board. Uneven material output, adjustable die lip opening, if the flow rate is too large, the choke bar can be adjusted, the formula is adjusted, generally the inner lubrication has more middle thickness, and the outer lubrication has more feeding on both sides.
6.Changes in the thickness and texture of plates that are likely to occur during the shift. The main reason is related to the mixing. After the last shift, the interval between mixing is long after the next shift. The mixing barrel is cooled well. The first pot is pre-plasticized, which is the same as before Differences are formed, and other conditions are unchanged, it is easy to produce fluctuations, which can be adjusted by adjusting traction, processing temperature or through management
