提高流动性能

Improve flow properties

空心玻璃微珠是微小的球体,球型率大,具有滚珠轴承效应,能提高流动性,能降低树脂混

合物的黏度和内应力。因此,在加工过程中复合材料动态生热少,能防止润滑不足和局部热

分解,注塑时更容易挤出,不仅减少制品的缺陷,而且使生产效率提高 15%-20%。

Hollow glass microsphere is a tiny sphere with high ball-type rate. Its ball-bearing

effect can improve its mobility and reduce the viscosity and internal stress of resin

mixture. Therefore, during processing, less heat is produced in composite materials

so as to prevent inadequate lubrication and partial thermal decomposition. It is more

likely to extrude when molding, which can not only reduce defects in products, but

also improve the production efficiency by 15% -20%.

较高的树脂替代率

A superior substitute of resin

空心玻璃微珠具有最小的比表面积及低吸油率,它在混合物中能够具有良好的分散性,很容

易被压紧和融合,因此它具有很高的填充性能,可大大减少树脂的使用量,增加填料的用量,

有效减小 VOC 指标,同时降低了成本。

Hollow glass microspheres occupy less surface area, low oil-absorption rate, and

evenly disperse in mixture. Its easy compression and integration permit high filler

loadings. It significantly reduces the consumption of resins, increases the amount of

filler, and effectively reduces VOC indicators, and costs as well. 降低制品的收缩和曲翘

Low shrinkage and warpage

空心玻璃微珠各向同性和高填充量的特性,使制品尺寸的稳定性非常高,能够减少收缩和翘

曲;若填充比例适当时,制品的韧性明显改善,抗冲击性显著提高,表面硬度增强。

Hollow glass microspheres have the feature of isotropism and high-filling, hence the

dimensional stability of the product will be very high and it will reduce the shrinkage

and warpage. With an appropriate filling ratio, the toughness of the products,

impact-resistance and surface hardness can be significantly improved.

体积成本更经济

More economical

高性能空心玻璃微珠的密度仅是树脂密度的几分之一,只需使用少量的空心玻璃微珠就能替

换较重的材料。当考量单位体积成本,而非单位重量成本时,高性能空心玻璃微珠能显著降

低成本。

The density of high-performance hollow glass microspheres is only a fraction of that

of the resin. A small amount of hollow glass microspheres will be able to replace

heavier materials. When considering the cost per unit volume, rather than cost per

unit weight, high-performance hollow glass microspheres can significantly reduce

costs.

调节产品密度

Adjusting product density

空心玻璃微珠的密度通常在 0.20~0.60g/cm3,而矿物填料密度一般都在 2.7~4.4 g/cm3 左右

(我们使用的数据必须是微粒的真实密度)。为了得到相等的体积,必须使用 14 千克或更

多的滑石粉才能得到使用 1 千克的空心玻璃微珠的效果。因此添加不同比例的空心玻璃微珠

就能够得到你所想要的理想密度。

The density of hollow glass microspheres is usually 0.20 ~ 0.60g/cm3, and the

density of mineral filler is generally around 2.7 ~ 4.4 g/cm3 (The data adopted is the

true particle density). In order to obtain the equal size, 14 kilograms or more of talc

must be used to obtain the same effect of 1 kg of hollow glass microsphere. Hence

the desired ideal density can be obtained by adding appropriate proportions of

hollow glass microspheres
