FAQ: Professional FAQ on Dry Ground Muscovite Mica Powder
Q1: What distinguishes “dry ground” muscovite from wet ground in terms of structure?
A: Dry Ground Muscovite Mica Powder retains a higher aspect ratio and natural platelet morphology due to absence of water-based abrasion, resulting in superior electrical insulation and reinforcement abilities.
Q2: What is the typical particle size distribution and how does it affect performance?
A: D90 sizes range from 20–150 μm. Finer particles yield denser films and smooth interfaces in coatings, while coarser particles are optimal for polymer compounding (lower percolation, increased dimensional stability).
Q3: What purity assurances are provided?
A: KeHui guarantees muscovite content >96%, verified by XRD/EDX and LOI <1.0%, compliant with ISO 3262-20 and ASTM D351-87 standards.
Q4: Are there flame retardant or chemical inertness advantages?
A: Yes. Limiting Oxygen Index (LOI) is substantially higher (≥45), which means improved non-combustibility in plastics. Mica is also inert to most acids, alkalis, and solvents.
Q5: How is quality assurance managed for each batch?
A: Each lot is digitally barcoded and tracked throughout production. Multi-stage QC includes particle sizing (laser analyzer), iron/alkali content, moisture, and dielectric tests, with data sent to the client.
Q6: What standards does the product comply with for export?
A: Strict adherence to ISO 9001:2015, ISO 3262-20, ASTM D351-87. Full REACH, RoHS, SGS, FDA (non-food contact) compliance available on request. Documentation and MSDS supplied per shipment.
Q7: Does the mica contribute to longevity of final industrial assets?
A: Absolutely. Pipes, tanks, equipment using Dry Ground Muscovite Mica Powder demonstrate up to 40% longer replacement intervals in corrosive and high-voltage environments per customer maintenance logs.
Q8: Can you provide custom surface modifications, such as silane treatment?
A: Yes. Options include silane, titanate, or acrylic modification to enhance interface bonding for plastics/rubbers, tailored to client’s compounding needs.
