Custom Fabrication of Frosted Lines Quartz Plate

Custom Fabrication of Frosted Lines Quartz Plate

Frosted Lines quartz plate (also known as frosted stripe quartz plate) is a special type of quartz glass plate with frosted stripes on its surface, commonly used in fields such as optics, semiconductors, photovoltaics, etc. It plays a role in diffuse reflection, anti glare, or light guidance.
Customized parameters:
Dimensions: length, width, thickness (common thickness 1-20mm, ultra-thin or thickened requires special processes).
Frosted Lines parameters: line width, spacing, depth (usually line width 0.1-2mm, spacing 1-10mm, adjustable).
Quartz material: high-purity quartz (SiO ₂ ≥ 99.99%), ultraviolet grade quartz (low hydroxyl) or ordinary quartz.
Light transmittance/haze: Adjust the surface roughness according to the degree of sanding (such as Ra 0.1-1.5 μ m).
Other requirements: temperature resistance (-50 ℃~1200 ℃), corrosion resistance, edge treatment (chamfering, drilling), etc.
Frosted Lines process:
Sandblasting process: By high-pressure spraying diamond sand to form frosted lines, the cost is low but the accuracy is poor (suitable for rough lines).
Laser engraving: High precision (up to ± 0.05mm), capable of complex patterns, but high equipment cost.
Chemical etching: Corrosion with hydrofluoric acid solution, uniform surface, suitable for fine lines (line width<0.5mm).

Fused Quartz Glass Features:

Fused quartz glass is a special industrial glass made of silicon dioxide. It is a very good basic material. Quartz glass has a series of excellent physical and chemical properties.

1. High temperature resistance. The softening point of fused quartz glass is about 1730℃ and can be used for long time working under 1100℃~1250℃.  And working at 1450℃ in a short time.

2. Corrosion resistance. In addition to hydrofluoric acid, fused quartz glass is inert to other acids. Its acid resistance is 30 times as ceramic, 150 times as stainless steel. Especially, any other material cannot make a comparison with chemical stability of fused quartz at high temperature

3. The thermal stability is good. Thermal expansion coefficient is extremely small. And it can withstand severe temperature changes such that heating up to 1100℃ and putting it in normal temperature water will not crack.

4. The light transmittance is good. Quartz glass has good transmittance in the whole spectral band from ultraviolet to infrared. The transmittance of the visible light is above 95%. Especially in the ultraviolet spectrum band and the maximum transmittance is over 85%.

5. The electrical insulation performance is good. Resistance value of quartz glass equaling to 10000 times of ordinary glass. It is an excellent electrical insulating material and has good electrical properties even under high temperature.
