Diatomite Powder CAS 68855‑54‑9 for Cutting Fluid and Metalworking Fluid Filtration
Diatomite Powder CAS 68855‑54‑9 is industrial‑grade flux‑calcined diatomite filter aid specially for metalworking fluid purification. Its developed porous structure efficiently captures metal chips, fine grinding debris, abrasive particles and oxidation sludge generated during machining. It reduces fluid turbidity, inhibits sediment accumulation and prolongs service cycle of cutting fluid. Good chemical inertness makes it compatible with most water‑based and oil‑based metalworking coolants.
Product Overview
Diatomite Powder CAS 68855‑54‑9 for Cutting Fluid and Metalworking Fluid FiltrationCutting fluid and grinding coolant will accumulate a large amount of metal fines, abrasive dust and sludge after long‑time circulation. These impurities accelerate fluid deterioration and cause scratch defects on workpiece surface. This diatomite powder forms rigid porous filter bed to separate solid contaminants, purifies circulating coolant and supports fluid recycling for mechanical processing workshops.
Key Features
- CAS Number: 68855‑54‑9, Industrial Diatomite Powder for Metalworking Fluid
- High chemical inertness, compatible with water‑soluble and oil‑based cutting fluids
- Excellent removal effect for metal chips, grinding debris, abrasive particles and sludge
- Reduce fluid turbidity, extend service life of cutting and grinding fluid
- Stable permeability, slow filter bed clogging under high solid‑load condition
- Low soluble impurities, will not destroy coolant additive system
- Stable particle‑size distribution, consistent filtration performance batch‑to‑batch
- Suitable for pressure filter, plate‑frame filter and coolant recycling equipment
Main Applications
‑ Solid‑liquid purification for various water‑based cutting fluid and grinding fluid‑ Filtration treatment of oil‑based metalworking coolant‑ Remove metal sludge in mechanical processing circulating fluid system‑ Pre‑filtration for regeneration and reuse of waste metalworking fluid
Usage Guidance
Suitable for pre‑coat filtration or body‑feed adding mode. Adjust dosage according to pollution degree of cutting fluid. Perform small compatibility test before mass application. Keep diatomite dry to prevent caking. Wear dust mask during powder handling.
Storage & Package
