| Nano calcium carbonate slurry for drilling fluid is a commonly used high-quality additive in drilling fluid. This product uses high-quality nano-calcium carbonate resources and uses a unique low-temperature wet dispersion method to improve the physical properties of the product, effectively prevent plate precipitation, and make the product After being left for a period of time, it can still be stirred evenly and there is no hardening on the bottom, so it can be used continuously without affecting the effectiveness of the product. This product has strong anti-leakage and sealing effects, can increase lubrication, and plays the role of wall and rod protection. The product is acid-soluble and does not harm the reservoir. It is suitable for all types of drilling fluid systems. 1.Technical indicators： TECHNICAL DATA SHEET NPCC-902 | Index | Appearance | White suspended paste | Average particle size um | ≤0.95 | Particle shape | Cube | pH (10g dissolved in 90ml water) | 8.0-10.0 | Solid content % | 65±2 | Main content (calculated as CaCO3) (dry basis) % | ≥98 | Loss on ignition (dry basis) % | ≥45.8 | Fe % | 0.05 | Mn % | 0.006 | Package | Ton barrel |
