Reasons for SPC floor fracture and tile deformation And how to avoid it
SPC flooring experiences fracture and tile deformation (similar to tile shaped arch deformation) due to various reasons. The following are corresponding avoidance methods for different problems:
Reasons for fracture and avoidance methods
Reason
Poor quality
1)Low quality raw materials: Some manufacturers use inferior polyvinyl chloride (PVC) resin or a large amount of recycled materials to reduce costs, resulting in poor physical properties of the floor, such as strength and toughness. Meanwhile, poor quality or improper proportioning of fillers such as calcium carbonate can also affect the overall performance of the floor, making it prone to breakage during normal use.
2)Production process defects: During the production process, the process parameters of key links such as rolling and extrusion are not accurately controlled, such as inappropriate temperature and pressure, which can result in insufficient bonding between the layers of the floor or the presence of stress concentration areas inside, reducing the overall strength of the floor and increasing the risk of fracture.
Installation error
1)Improper handling of the base layer: uneven installation of the ground, presence of debris, or insufficient strength of the base layer can result in uneven stress on the SPC floor after installation. In daily use, excessive local pressure can easily lead to stress concentration, causing the floor to break at weak points.
2)Incorrect setting of expansion joints: SPC flooring may expand and contract due to temperature and humidity changes. If expansion joints are not reserved or the reserved width is insufficient during installation, when the expansion and contraction of the floor are limited, internal stress may accumulate, which may cause fracture.
Poor operating environment
1)External impact: Frequent heavy object impacts and sharp object scratches that exceed the load-bearing capacity of SPC flooring can directly damage the surface and internal structure of the flooring, forming cracks that expand over time and lead to fracture.
2)Large temperature and humidity changes: SPC flooring has a certain range of adaptability to environmental temperature and humidity. In environments with sudden temperature changes or significant humidity fluctuations, the flooring generates significant stress due to thermal expansion and contraction, and under repeated action, the structure is damaged and prone to fracture.
Avoiding methods
1)Strictly control product quality: choose well-known SPC flooring products with good reputation, check the quality inspection reports of the products, and ensure that their various performance indicators meet national standards. For example, the wear resistance and bending strength of the floor should meet the corresponding level requirements.
2)Standardize the installation process
Base pre-treatment: Thoroughly clean the ground before installation to ensure that the base is flat, dry, and free of debris. For uneven ground, it is necessary to polish or level it; If the grassroots is loose, reinforcement treatment should be carried out first.
Reasonably reserve expansion joints: Reserve expansion joints according to standard requirements based on the installation site area, usage environment, and floor specifications. Generally speaking, the width of expansion joints at the edges of walls, columns, and other locations should not be less than 8-10mm.
3)Optimize the usage environment
Reduce external damage: When moving furniture and equipment, take protective measures to avoid heavy objects directly hitting the floor; Carpets or floor mats can be laid in areas that are frequently moved or susceptible to friction.
Stable temperature and humidity: Install temperature and humidity control equipment to maintain indoor temperature between 18-28 ℃ and relative humidity between 40% -60%, reducing the impact of temperature and humidity changes on the floor.
Reasons for tile deformation and avoidance methods
reason
Damp influence
1)Lack of moisture-proof measures: The ground moisture-proof treatment is not in place, such as the absence of moisture-proof film or poor quality or damage of moisture-proof film. Underground water vapor is easy to penetrate below the floor, causing the floor to expand due to moisture and bulge upwards due to surrounding restrictions, resulting in tile deformation.
2)High environmental humidity: Prolonged exposure to high humidity environments, such as the rainy season in the south or poorly ventilated damp spaces, can cause SPC flooring to continuously absorb moisture from the air, resulting in uneven expansion of various parts and tile deformation.
Installation issues
1)Improper use of glue: When using glue for installation, uneven application, excessive or insufficient usage, and poor quality of glue can affect the bonding effect and stability of the floor, leading to inconsistent shrinkage or expansion and causing tile deformation.
2)Irregular splicing: The floor joints are not tightly aligned, leaving large gaps, and external moisture, dust, etc. are easy to enter, causing the edges of the floor to become damp and deformed, resulting in tile deformation.
Product inherent defects
1)Poor structural stability: The multi-layer structure design of the floor is unreasonable or the compatibility of materials in each layer is poor, resulting in the overall instability of the floor structure, which is prone to deformation when environmental factors change.
2)Poor material performance: The material that makes up SPC flooring has unstable properties, such as poor thermal stability of PVC material, which is prone to size changes when temperature changes, increasing the possibility of tile deformation.
Avoiding methods
Do a good job in moisture-proof work
1)Ground moisture-proof treatment: Before installation, lay high-quality and complete moisture-proof film on the ground to ensure good sealing at the overlap of the moisture-proof film, and flip up a certain height at the corner of the wall to prevent water vapor from entering.
2)Control environmental humidity: Install ventilation equipment such as exhaust fans and fresh air systems to enhance air circulation and reduce indoor humidity; During high humidity seasons, dehumidifiers can be used to control humidity.
Ensure installation quality
1)Correct use of glue: Choose high-quality glue that is compatible with SPC flooring, apply the glue evenly according to the product instructions, control the amount, and ensure that the flooring is firmly adhered and evenly stressed.
2)Standardized splicing operation: During the installation process, carefully align the floor joints to ensure tight and seamless splicing. Use specialized tools to assist in splicing and ensure the quality of splicing.
3)Select high-quality products: Choose SPC flooring with reasonable structural design and stable material properties. For example, the core layer of the floor is made of high-density and high-strength materials, and the surface wear-resistant layer and bottom layer have good flexibility and stability to improve the overall deformation resistance of the floor.
