Glass Industry
Industrial mineral solutions — PT Wira Energi Utama, North Sulawesi
Glass Industry Overview
Limestone is the third-largest component in soda-lime glass manufacturing, providing chemical stability.
Products Used
Stabilizer utama dalam campuran batch kaca
Role of Limestone / CaCO3 in Glass Industry
CaO acts as a stabilizer, making glass resistant to water and chemical dissolution.
Technical Requirements
| Parameter | Value / Standard |
|---|---|
| CaO Minimum | > 54% |
| Fe2O3 Maksimum | < 0.05% |
| SiO2 | < 0.5% |
| Ukuran Butir | Mesh 40 – Mesh 100 |
Process Integration
- 1
Batching
Batu kapur digiling halus dan dicampur dengan pasir silika dan soda ash.
- 2
Melting
Campuran dilelehkan dalam furnace pada suhu 1.500°C.
- 3
Refining
Gelembung gas dihilangkan untuk menghasilkan kaca bening sempurna.
- 4
Forming
Kaca cair dibentuk menjadi lembaran (float) atau botol.
Industry Pain Points
Kandungan besi (Fe2O3) tinggi menyebabkan kaca berwarna hijau atau gelap
Ukuran butir tidak seragam memicu titik-titik tidak meleleh (stones) pada kaca
