Furniture surface paint film cold liquid resistance test

The cold liquid resistance test of the paint film on the furniture surface mainly simulates the liquid spilled on the furniture surface in real life to evaluate the corrosion resistance of the furniture surface against the liquid. It provides technical support for improving the quality of the furniture surface, standardizing the order of the furniture market, and providing technical guarantee for protecting the legitimate rights and interests of consumers.
Zhongke Testing Reliability Experiment Center has the capability to test the reliability of various furniture surface paint films, and provides professional reliability testing services such as cold liquid resistance testing for furniture surface paint film products.

The cured surface of all painted furniture, not suitable for leather furniture and textile furniture surfaces.

Place the round paper soaked in the test liquid on the test surface and cover the round paper with a glass petri dish. After the specified test time is reached, remove the round paper piece and leave it on the test surface for 16 h~24 h.
Dry the test surface and check the damage, such as fading, luster and discoloration, bubbling, and swelling under the specified lighting conditions. Test results are evaluated using numerical grades.

Level 1: No changes
Test area is indistinguishable from adjacent areas
Level 2: Minor changes
Only when the light source is projected onto the test surface and reflected into the observer's eyes, the test area can be distinguished from adjacent areas, such as fading, tarnishing, and discoloration; there is no change in the structure of the test surface, such as swelling, fiber protrusions, cracking, and bubbling
Level 3: Moderate changes
Visible in several directions, the test area can be distinguished from adjacent areas, such as fading, tarnishing, and discoloration; there is no change in the test surface structure, such as swelling, fiber protrusions, cracking, and bubbling
Level 4: Significant changes
Visible in all viewing directions, the test area is clearly distinguishable from adjacent areas, such as fading, tarnishing, and discoloration; and/or there are slight changes in the structure of the test surface, such as swelling, fiber protrusions, cracking, and bubbling
Level 5: Severe changes
The structure of the test surface is significantly changed, and/or it fades, tarnishes, and discolors, and/or the surface material is completely or partially removed, and/or the filter paper sticks to the surface.
