White fused aluminum oxide for floor wear layer White Fused Aluminum Oxide is a premium, synthetic abrasive grit that is broadcast (sprinkled) into the surface coating of resinous floors (like epoxy or polyurethane) to create an extremely durable, slip-resistant, and long-lasting wear layer. It is the industry standard for enhancing the performance of industrial and commercial floors.
什么类型的白色刚玉微粉适合汽车涂料？ 1. 什么是白刚玉？为什么适用于汽车涂料？ 白刚玉的主要化学成分是α-Al₂O₃，其纯度极高（通常为≥99%）。 其适用于汽车涂料的主要特性包括： 高硬度（莫氏硬度9.0，仅次于金刚石和碳化硅）：有效切割和平滑油漆表面。 纯度高、白度纯净：可避免二次污染。这对于具有严格颜色要求的汽车涂料至关重要。 优异的韧性：颗粒在压力下不易断裂，保持均匀的切削力。 优异的化学稳定性：不与酸或碱发生反应，不影响涂层的化学性能。 粒度分布均匀：可加工成各种规格，从粗到细（微米甚至纳米级），满足不同的精度要求。 二、白刚玉微粉在汽车涂料中的应用 1. 预处理：基材预处理 在涂上新油漆之前，车身底部（通常是金属或塑料）需要进行预处理以增强涂层的附着力。 目的：对基材进行微打磨以去除氧化层和杂质，形成粗糙的“锚”表面，以便更好地附着后续底漆。 应用：常用于喷砂。粗粒白刚玉（如F80-F220）因其硬度高、杂质含量低而更常用于喷砂，从而获得干净、均匀粗糙的表面。 2. 中涂层：涂层打磨 这是白刚玉微粉最传统和最主要的应用，用于打磨底漆和清漆。 底漆（中漆）打磨： 应用：白色刚玉可防止颜色渗透到浅色底漆中。 透明油漆抛光： 目的： Restoration: Removes oxide layers, minor scratches, orange peel, and dust specks from clear paint. Finishing: Achieve a mirror-like finish on new cars or high-end detailing. Summary: White corundum powder is crucial for
What is the purpose of pickling white corundum powder? Removing metal impurities During the pulverization process (e.g., roller grinding), metal impurities such as iron, nickel, and chromium may be introduced due to equipment wear, or small amounts of metal oxides (such as Fe₂O₃) may remain in the raw material. Pickling typically uses acidic solutions such
