PVC floor color difference problem

In the process of purchasing PVC flooring, many customers will pay attention to the color difference between the PVC floor sample and the actual received goods, because the floor is a building material for large-scale paving, and the color will affect the overall decoration effect. You may as well imagine that if the color difference between the PVC floor sample and the actual received goods is too large, it will undoubtedly bring a lot of unnecessary trouble to the decoration project. So, how to determine the color difference between the PVC floor sample and the actual received goods, let us take a look at the following content together.

Causes of color differences in PVC flooring production

At FARFLY, we have identified 3 core factors through ISO 9001 certified quality audits:

1. Raw material batch differences. According to ASTM D6868, PVC resin suppliers allow a ±5% deviation in pigment concentration between batches

2. Process parameter fluctuations: Temperature fluctuations exceeding 2°C during the calendering process will affect color presentation

3. Differences in lighting conditions: CIE standard light source D65 will produce a 15%-20% visual difference compared to typical warehouse lighting

Other methods to confirm the color difference

To accurately determine the color difference between the PVC floor sample and the actual received goods, we can use some scientific methods,

1. Compare under the same lighting conditions, put the sample and the actual received PVC floor together, preferably natural light, because different light colors will interfere with judgment.

2. Use a professional colorimeter to measure. A professional colorimeter can give a scientific and accurate color difference value between the sample and the actual goods, so that the degree of color difference can be seen more objectively.

3. Organize multiple people to conduct subjective evaluation. Different people observe from different angles. Combining everyone's opinions, it can also be judged whether there is a color difference.

Ensure the color consistency of PVC flooring

In order to avoid obvious color difference between PVC flooring samples and actual goods received, everyone should be cautious when choosing suppliers. For example, choose some reputable manufacturers with mature production technology. They have strict control over raw materials and production processes, and have rich experience, which can effectively reduce the probability of color difference. In addition to the above reasons, we must also store and install the goods in the correct way when we receive them, so as to reduce the impact of the external environment on the color of the floor, thereby ensuring the consistency of the color of the PVC floor and putting a perfect end to the decoration factory.
