玻璃粉

玻璃粉

末为无定型硬质颗粒，生产中使用原料为pbo、 sio2、tio2等电子级原料混匀后，在 高温进行固相反应，形成无序结构的玻璃均质体，化学性质稳定，其耐酸性已远远超过氧化铅，但在化学组成表达中按通常惯例折合成氧化物形成，如： pbo ， sio2 等表示。请注意区别.

　　物理指标：

　　外 观：白色粉末

　　白 度：≥93

　　ph 值：6-7

　　平均粒径：2.5±0.5um

　　比 重：2.7g/ml

　　吸 油 量：28±2.5g/100g

　　磨氏硬度：7.8

　　化学成分：硅酸盐类

特性及应用建议：

　　1、玻璃粉透明度好、硬度高、粒径分布均匀。

　　2、玻璃粉分散性好，与树脂和油漆体系中的其他成分相溶性佳。

　　3、玻璃粉经多次表面处理，在油漆体系中作填充，漆膜不带蓝光，重涂性好。

　　4、用在高档耐刮伤面漆中，可增加面漆的硬度、韧度，提高漆膜的抗刮伤性能，具有消光作用，可提高漆膜的耐候性。

　　5、同比滑石粉，玻璃粉在油漆开稀后较易沉淀，故防沉措施应适当加强。

应用说明玻璃粉是一种易打磨抗划高透明粉料，粒径小、分散性好、透明度高、防沉效果较好；经过多次表面改进，具有良好的亲和能力，并且有较强的位阻能力，能方便地分散于涂料中，成膜后可增加涂料丰满度，制成的水晶透明底漆类，既保持清漆的透明度，又提供良好的打磨性。主要用于生产高档家俱时作水晶底漆用。也广泛用作装修用底面两用漆。适用范围：聚脂漆、聚氨脂漆、硝基漆、醇酸漆、丙烯酸漆、乙烯酸漆等，pe透明底漆等。

玻璃粉在涂料中的应用　主要用于生产高档家具时作水晶底漆用，也广泛用作装修用底面两用漆。建议添加比例5%-10%。

化妆品级：用在眼影等方面

glass beads

for the amorphous hard particle, at the end of the production of raw materials for use of pbo, sio2, tio2 electronic grade raw materials blending, such as in the high temperature solid phase reaction, formation of disordered structure homogeneous body of glass, chemical stability, acid resistance has far more than lead oxide, but in chemical composition expression according to the practice usually converted into oxide formation, such as pbo, sio2, etc. please pay attention to the difference.

physical indicators:

outside view: white powder

whiteness: p. 93

ph: 6-7

the average particle size: 2.5 + / - 0.5 um

weight: 2.7 g/ml

oil absorption: 28 + / - 2.5 g / 100 g

abrasive hardness: 7.8

chemical composition: silicate class

characteristics and application advice:

1, glass powder, good transparency, high hardness, particle size distribution uniformity.

2, glass powder, good dispersibility, and other components in the resin and paint system good intermiscibility.

3, glass powder, the surface treatment for many times, in paint system for filling and coating film without blue light, good painting.

4, in the high-grade scratch resistant finish, can increase the hardness, toughness, and paint to improve the film scratch resistance, have extinction effect, can improve the weather resistance of paint film.

5, compared to the talcum powder, glass powder paint in the open after precipitation more easily, so the anti-settling measures should be appropriate to strengthen.

application shows that glass powder is a kind of easy grinding resistance to delimit high transparent powder, small particle size, good dispersion, high transparency, anti-settling effect is better; after multiple surface improvement, has the good affinity, and has strong resistance ability, can be easily dispersed in coating, fullness to paint after the film, made of crystal transparent primer class, both keep the transparency of varnish, and provide a good polishing. mainly for the production of high-grade crystal primer used in furniture. also widely used as decoration floor and paint. scope of application: get together fat lacquer, get together ammoniac fat lacquer paint, nitro paint, alkyd paint, acrylic acid, ethylene acid paint, pe transparent primer, etc.

glass powder during coating application mainly for the production of high-grade furniture for crystal primer, also widely used as decoration floor and paint. suggest to add 5% to 5%.
