填料用实心玻璃微珠

DH Brand Solid Glass Microspheres (Filler Grade)

产品概述 | Product Description

道弘（DH）牌填料用实心玻璃微珠由优质钠钙玻璃经高温熔融、精密球化工艺精制而成，外观为无色透明或白色圆球状颗粒，化学稳定性优异，耐酸碱腐蚀。本产品作为高性能无机功能性填料，广泛用于塑料、橡胶、涂料、密封胶、人造石材等复合材料体系，可有效降低制品收缩率，提高硬度、耐磨性、抗冲击性及表面光洁度。圆球状结构能显著改善材料流动性，便于注塑成型加工。

DaoHong (DH) Solid Glass Microspheres are made from high-quality soda-lime glass through advanced high-temperature melting and precision spheroidization. They appear as colorless, transparent spherical particles with excellent chemical stability and acid/alkali resistance. As a premium inorganic functional filler, they are widely used in plastics, rubber, coatings, sealants, and artificial stone to reduce shrinkage, enhance hardness, abrasion resistance, impact strength, and surface finish. The spherical structure significantly improves material flowability for better processing.

使用说明 | Usage Instructions

建议在与基体树脂混合时采用低速搅拌，以避免微珠破碎，确保分散均匀。添加量通常为总质量的5%~30%，具体比例需根据终端产品的性能要求进行调整。使用前请确保材料干燥，避免受潮结块影响分散效果。

Use low-speed mixing when blending with matrix resins to prevent bead breakage and ensure uniform dispersion. Recommended loading: 5%~30% by total weight, adjustable based on end-product performance requirements. Ensure material is dry before use to avoid caking.

包装与储存 | Packaging & Storage

包装：25kg/袋（防潮牛皮纸袋/编织袋/纸桶），支持定制包装规格。储存：存放于干燥、通风的库房内，防止受潮结块。运输：防止挤压、防雨淋。

Packaging: 25kg/bag (moisture-proof kraft bag/woven bag/fiber drum). Custom packaging available. Storage: Keep in dry, well-ventilated warehouse. Prevent moisture and caking. Transportation: Avoid compression and rain exposure.
