First, the choice of pigment is crucial. High-quality pigments with strong light resistance and weather resistance should be selected, such as titanium dioxide and iron oxide series pigments in inorganic pigments. Compared with some organic pigments, they have better stability and can withstand long-term sunlight and erosion by various environmental factors. In the production process, strictly control the quality and addition ratio of pigments to ensure uniform and lasting color.
Secondly, the use of anti-ultraviolet additives is one of the key measures. Ultraviolet rays are one of the main factors causing the fading of track membranes. Adding ultraviolet absorbers and light stabilizers can effectively block the damage of ultraviolet rays to pigment molecules. These additives can absorb the energy of ultraviolet rays and convert them into harmless heat energy to dissipate, or prevent the occurrence of photooxidation reactions by capturing free radicals, thereby protecting the chemical structure of the pigment and maintaining the color brightness of the track membrane.
The surface treatment of the track membrane can also improve the color stability to a certain extent. Special surface coating technology, such as transparent weather-resistant coating, can form a protective film on the surface of the runway membrane, reduce the direct contact between ultraviolet rays, moisture and pollutants and pigments, and reduce the risk of fading. At the same time, this coating can also enhance the wear resistance and chemical corrosion resistance of the runway membrane, and further protect the overall performance of the runway membrane.
In terms of production technology, optimizing the vulcanization process has a positive effect on color stability. Reasonable control of vulcanization temperature, time and pressure to ensure that the rubber molecules are fully cross-linked to form a stable structure, so that the pigment can be better dispersed and fixed in the rubber matrix, reducing the migration and fading of pigments caused by molecular chain movement.
In addition, daily maintenance should not be ignored. Clean the runway regularly to remove dust, dirt and debris on the surface to prevent them from chemically reacting with the runway membrane under the action of ultraviolet rays and accelerating fading. At the same time, avoid using highly corrosive detergents to prevent damage to the surface of the runway membrane and pigments.
Control of environmental factors can also help improve color stability. For tracks installed in areas with strong direct sunlight, you can consider building shading facilities, such as awnings or planting tall trees, to reduce the time the track membrane is directly exposed to ultraviolet rays, reduce the fading rate, and extend the color retention period of the track membrane.
By selecting high-quality pigments, adding anti-ultraviolet agents, optimizing surface treatment and production processes, and strengthening daily maintenance and environmental control, the color stability of baimisheng prefabricated rubber track membrane can be effectively improved, fading can be prevented, and its appearance and performance can be maintained for a long time, providing users with high-quality sports venues.
