Increase moisture resistance

在容易分解、潮解的粉末或颗粒外包一 层稳定包衣层，防止粉末或颗粒因含水量或水分而变质。

To coat easily decomposing or deliquescent powders or granules with a stable coating layer to prevent deterioration caused by moisture content or humidity.

改善外观

Improve appearance

湿法离心制粒之后颗粒成球形状，颗粒牢 固性增强，可以与其他组分粒径保持一致， 易于后期混合，美观性提高。

After wet centrifugal granulation, the particles form a spherical shape, their robustness is enhanced, and they can maintain a consistent particle size with other components, making subsequent mixing easier and improving the overall appearance.

提高流动性 

Improve flowability

粉末流动性差，粘附性、凝集性强，在粉末表面包覆一层薄膜后，流动性提高，内聚力降低，便于运输储存。

For powders with poor flowability and strong adhesion or agglomeration, coating their surface with a thin film improves flowability, reduces cohesion, and facilitates transportation and storage.

增加遮光性

Increase light-shielding properties

具有极强光敏性药物，暴露在日光和紫外线下可降解为许多光分解产物，包覆例如二氧化钛薄膜后，可以显著降低药物的光降解水平。

For highly photosensitive drugs that can degrade into numerous photolysis products when exposed to sunlight and ultraviolet rays, coating them with a film such as titanium dioxide can significantly reduce the level of photodegradation.

cohesion, and facilitates transportation and storage.

调解释放速度

Regulate the release rate

制备缓释肠溶药物，在粉末或颗粒表面包覆一层隔离层，避免药物对胃的刺激，防止胃酸和胃酶对药物的破坏，并能减少服药的次数，降低不良反应。

To prepare sustained-release enteric-coated drugs, an isolation layer is coated onto the surface of the powder or granules. This prevents gastric irritation caused by the drug, protects it from being destroyed by gastric acid and enzymes, reduces the frequency of administration, and minimizes adverse reactions.

掩盖不良气味

Mask unpleasant odors

在颗粒外层包覆一层稳定的高分子聚合物薄膜（保护衣），提升药物适口性增加颗粒稳定性，且衣层牢固光滑、轻薄。

A stable polymer film (protective coating) is applied to the outer layer of the granules to enhance palatability, increase granule stability, and ensure the coating is strong, smooth, and thin.
