Flux Calcined Diatomite Type 577 CAS 68855‑54‑9 Extra Coarse for High Flow Rate
Flux Calcined Diatomite Type 577 CAS 68855‑54‑9 is extra‑coarse flux‑calcined diatomite designed for maximum flow capacity. Its oversized rigid porous skeleton builds highly permeable filter bed with minimal flow resistance. It can withstand heavy solid loads and maintain stable throughput in demanding industrial conditions. Chemically inert with low soluble extractables, it is widely used as pre‑coat support layer and primary filtration medium for high‑flow heavy‑duty processes.
Product Overview
Flux Calcined Diatomite Type 577 CAS 68855‑54‑9 Extra Coarse for High Flow Rate is heavy‑duty extra‑coarse filter aid. Compared with very‑coarse grades, Type 577 has further enlarged particle and pore size, delivering ultra‑high permeability. It is mainly applied for heavy‑load pre‑coat base layer and primary filtration for liquids containing large quantity coarse suspended solids, effectively reducing pressure build‑up and extending filter running cycle.
Key Features
- CAS Number: 68855‑54‑9, Flux Calcined Diatomite Type 577 Extra Coarse Grade
- Extra‑coarse controlled particle size, ultra‑high permeability for high flow rate
- Robust rigid skeleton, anti‑compression performance under heavy solid loading
- Greatly reduce initial filtration resistance, slow pressure rise tendency
- Excellent pre‑coat supporting layer, prevent penetration of other filter aid powders
- Chemically inert, low soluble leachables, compatible with most industrial liquids
- Reliable particle‑size consistency, stable filtration performance batch‑to‑batch
- Fit for leaf filter, pressure filter and plate‑frame filter for heavy‑duty production
Main Applications
‑ Extra‑high‑flow pre‑coat supporting base for large industrial filter equipment‑ Primary filtration of liquid with massive coarse suspended solids‑ Heavy‑duty pre‑coating for chemical processing and waste liquid treatment‑ Base layer before applying medium or fine filter aid for secondary filtration
Usage Guidance
Primarily used as pre‑coat base layer, calculate dosage based on filter area. Complete pre‑coating formation before feeding process liquid. This grade is good for coarse impurity interception; fine colloids require secondary filtration with finer diatomite. Control pre‑coating flow velocity properly. Pilot test is required before mass‑scale operation. Wear dust mask during powder handling.
Storage & Package
Seal packages tightly. Store in dry ventilated warehouse, protect from moisture. Standard package: 25kg woven bag with PE inner liner. Shelf life: 24 months under dry sealed storage.
Service Support
Filtration test samples available. COA and technical datasheet can be provided upon request. Stable bulk supply capacity. Welcome to inquire factory quotation.
