Common Problems and Failure Analysis of Environmental Protection SPC Floor

FAQ of Eco-Friendly SPC Flooring

Q: Can it be used with floor heating?

A: Yes. It is very suitable for floor heating and has faster heat dissipation compared to other flooring materials.

Q: Can it be directly laid on top of tiles?

A: Yes, it can.

Q: Can it be directly laid on a cement surface?

A: Yes, as long as the cement surface is not sandy and has good flatness, it can be installed directly. If the ground is not flat, self-leveling is needed to even it out.

Q: Is self-leveling necessary before installation? Is it possible to simply level the ground?

Answer: SPC flooring does not require high requirements for the foundation. In general, leveling can be done as long as it is even. The differences in height cannot exceed 2-3mm within two square meters.

Q: Do we need a moisture barrier? Should we use skirting boards for finishing? Do we need to use adhesive?

A: In principle, a moisture barrier is not needed. SPC flooring has a sound-absorbing film on the back. Skirting boards are recommended for finishing. Locking flooring does not require adhesive.

Q: Will it warp, buckle, or shrink with water?

A: No, it will not.

Q: Does it produce an odor?

A: No, it does not.

Q: Will water leak at the locking intersection?

A: There won't be a problem with normal care. Use glass glue to seal the gap in the bathroom.

Q: Will it leave indentations if furniture is placed on it for a long time?

A: No, it won't. It can withstand a load of 2 tons in the compression test.

Q: How does it feel? Is it particularly hard?

A: It has good flexibility, is not cold, and has a better foot feel than typical floor materials.

Q: How about its soundproofing effect?

A: It has a sound insulation layer on the bottom and has very good sound absorption and insulation effects.

Q: How to measure the square meterage of the room?

A: Multiply the length and width of the space to be laid, add 2%-3% for wastage.

Q: Can it be used in the kitchen, bathroom, and balcony?

A: Yes. It is waterproof, stain-resistant, oil-resistant, and easy to maintain.

Q: Can it be laid in a herringbone pattern?

A: Usually not. SPC flooring is a locking type.

Analysis of Common Problems with SPC Flooring

The size of the SPC flooring is unstable, the shaping mold is incomplete, and the wall thickness is uneven

Cause: The internal and external lubricants in the formula are not reasonable, the feeding quantity and feeding speed are unstable, the screw and barrel are severely worn, and the clearance is not correct.

Solution: Improve the ratio of internal and external lubricants, correct the feeding errors, replace the barrel and screw, and adjust the clearance between the barrel and screw.

The appearance of the SPC flooring is not uniform in brightness, the color difference is significant, and irregular fish scales appear on the surface; the performance of the product is poor; the flexibility is poor, and the product is brittle, with poor resistance to impact

Cause: The formula structure is not reasonable, the inorganic filler is too high, the plasticization is poor, and the addition of impact-resistant materials is insufficient.

Solution: Adjust the formula structure, appropriately reduce the content of inorganic fillers, plasticize the material to about 65%, and add impact-resistant materials as appropriate.

The finished SPC flooring has bending, deformation, and local sinking

Cause: The head of the machine is not on the same plane as the shaping mold; the extrusion speed is too fast; the cooling water temperature is too high; the water pressure is too small, and the water flow is insufficient; the water and gas passages are not unobstructed, and the vacuum negative pressure is insufficient.

Solution: Correct the deviation of the head and mold of the machine to the same horizontal plane; reduce the extrusion speed and cooling water temperature; improve the water pressure and flow rate; adjust the vacuum negative pressure, and check that the water and gas passages are unobstructed.
