FAQs: Expert Answers on 40 mesh Dry Ground Muscovite Mica Powder factory

Q1. What is the core material composition of 40 mesh Dry Ground Muscovite Mica Powder factory products?

A1. The powder is composed primarily of muscovite mica: KAl₂(AlSi₃O₁₀)(F,OH)₂. This mineral's layered lattice imparts excellent electrical insulation, thermal stability, and chemical inertness. Trace contents (

Q2. How does "dry ground" process differ from "wet ground" mica powder?

A2. Dry ground grinding involves mechanical crushing of dried mica lumps using roller or hammer mills, preserving larger platelets and the native crystalline structure—ideal for high-sheen and barrier effect. Wet ground utilizes water-based mills, yielding fine and flexible particles but typically with lower brightness and aspect ratio, mostly for ultrafine cosmetic/paint use.

Q3. Which industry standards apply to 40 mesh Dry Ground Muscovite Mica Powder factory?

A3. KeHuiMica's powder complies with ISO 6131 (Mica specification), ASTM E11-17 (sieve), ISO 9001:2015 (QMS), SGS/Intertek for heavy metals, and RoHS directives for EU electronics and coating exports.

Q4. What packaging and transportation precautions are observed?

A4. Packaging employs 3-layer moisture-proof PP/paper bags (25/50kg) with PE linings, or 500–1000kg jumbo bags for bulk. All pallets are shrink-wrapped and can be shipped by container111 or air freight. Each lot is coded for traceability in supply chain management systems.

Q5. What mesh size distribution tolerance can be guaranteed?

A5. Mesh tolerance is ±3% (measured ISO 3310), with ≥98% of particles passing the 40 mesh sieve. Laser diffraction and image analysis verify PSD for each shipment.

Q6. What are recommended storage and shelf-life guidelines?

A6. Store in a dry, ventilated environment at room temperature. Sealed, undisturbed bags maintain stable parameters for 2+ years (verified by periodic accelerated aging tests; see industry study).

Q7. Can I request custom surface treatment or particle size adjustment?

A7. Absolutely—hydrophobic, silane, or titanate treatments are available, as well as custom mesh (10–800) and color/whiteness modifications. Please provide intended application and target specs for best fit-offer (MOQ may apply for specialty grades).
