Introduction
1. Background and significance of standard formulation
With the rapid development of photovoltaic power generation technology, high-purity quartz sand is a key basic material in the photovoltaic industry, and its quality directly affects the performance and life of solar cells. In order to meet the needs of the industry and standardize production and application, the GB/T 32649-2016 "High-purity Quartz Sand for Photovoltaic" standard came into being.
2. Comparative analysis of standard frameworks
| Technical indicators | Requirement range | Detection method |
|---|---|---|
| Silicon dioxide content | ≥99.99% | GB / T3 2 8 4 |
| Impurity element content | Total content≤25μg/g | S J3 2 2 8.7 |
| Particle size range | 70μm~350μm, cumulative mass fraction≥90% | SJ/T1 0 3 8 0 |
3. Technical requirements and practical applications
Case study: In the actual production of high-purity quartz sand for photovoltaics, a company successfully controlled the content of impurity elements below 15μg/g by optimizing the raw material screening and purification process, and achieved precise control of the particle size range, meeting the technical requirements of GB/T 32649-2016.
