La chambre d'essai de résistance aux intempéries aux UV joue un rôle important dans l'application de chapeaux de protection solaire. En tant que produit d'extérieur, sunscreen hats are often exposed to sunlight, and long-term UV irradiation will have an impact on their materials, comme la décoloration, material aging, strength reduction and so on. The UV aging test chamber can simulate the real UV radiation environment to evaluate the weather resistance and durability of the sunscreen cap.

In the UV aging test of sunscreen hats, the UV aging test chamber is usually used in the following aspects:

Evaluate color retention: The color stability of a sunscreen cap is an important indicator of its appearance quality. Through the UV aging test box, it can simulate the UV radiation under the sun, observe and evaluate the color retention of the sunscreen cap, and judge its fade resistance performance.

Durability assessment: The durability of sunscreen hats is crucial to their service life. Uv aging test chamber can simulate long time UV radiation exposure, evaluate the aging degree of sunscreen cap material, strength loss, judge its durability.

Material performance test: sunscreen hat material requirements have a certain degree of softness, tensile resistance and wear resistance and other properties. Uv aging test chambers can evaluate changes in physical properties of sunscreen cap materials, such as tensile strength, allongement à la rupture, and wear resistance.

Méthode de test
Use UV aging test chamber to test the aging resistance of sunscreen cap, peut généralement être réalisé selon les étapes suivantes:

La préparation des échantillons: Select the sunscreen cap sample that meets the requirements and ensure that the size and material of the sample are consistent with the actual product.

Définir les conditions de test: selon les exigences des tests ou les normes applicables, régler l'intensité du rayonnement UV, température, humidité et autres conditions de test.

Emplacement de l'échantillon: Place the sample of the sunscreen cap on the sample table in the UV aging test chamber to ensure that the sample is exposed to the light source of UV radiation.

Exécuter un test: Permettre à l'échantillon d'être exposé en continu au rayonnement UV et à d'autres conditions de test pendant une certaine période de temps selon les conditions de test définies.

Observation et évaluation: Observer et évaluer régulièrement les changements d’échantillons, y compris les changements de couleur, état de surface, material properties changes, etc., et enregistrer et enregistrer les données pertinentes.

Analyse des résultats: The aging resistance and expected life of the sunscreen cap were evaluated based on the sample changes and performance losses observed during the test.

Normes de l'industrie
Commonly used industry standards and guidelines for UV aging testing of sunscreen hats include:

ASTM D4329: Standard Test Method for outdoor UV Radiation aging of plastic materials and coatings.

OIN 4892-3: This standard specifies methods and procedures for UV radiation aging testing of plastic materials under laboratory conditions and is applicable to the testing of sunscreen hats.

Cas d'application spécifiques
Sports sunscreen cap: Sports sunscreen cap is often exposed to outdoor environment, Le test de vieillissement UV peut évaluer sa résistance aux intempéries et sa stabilité de couleur.

Casual sunscreen hats: Casual sunscreen hats are often exposed to UV radiation in daily use, and UV aging tests can evaluate their durability and appearance quality.

Children’s sunscreen caps: For children’s sunscreen caps, UV aging tests can evaluate the durability and safety properties of their materials.

Conseil: Specific application cases and applicable standards may vary depending on the type, material and target market of sunscreen hats. When performing UV aging tests, it is recommended to refer to applicable industry standards and relevant guidelines to ensure the accuracy and reliability of the tests.
