01 Feedstock
Ore, monomer, fibre, mineral or scrap that can legally become 矿物棉.
Making 矿物棉 is a chain: feedstock, conversion (Slag wool 19th c.; glass wool 1930s), forming, heat, finish, install.
Skip a step and the properties chapter is describing a different object.
工艺步骤
02 Conversion
Slag wool 19th c.; glass wool 1930s
03 Forming
Cast, spin, weave, sinter, foam, laminate or coat — the step that sets anisotropy.
04 Heat / cure
Temper, vulcanise, calcine or dry: skip it and the datasheet is fiction.
05 Finish
Coatings, sizings, facers, galvanizing, anodising, painting.
06 Install
Fasteners, adhesives, DFT, compression, dryness — site quality is a material property.
路径
Primary
Virgin route around US / Germany / Denmark.
Recycled / secondary
Recycling exists but quality or energy often disappoints.
Specialty
High-spec grades leave the commodity mill.
Site-applied
Coatings, sprays, casts — the factory is sometimes a jobsite.

极限
Envelope
Melting/softening softens ~1000 °C class (stone); conductivity λ ~0.032–0.040 W/m·K typical batts.
Environment
Moisture, UV, chlorides, alkalis or oxygen — pick the one that actually kills 矿物棉.
Code
Fire class A1 is a starting letter, not a wall rating.
Process energy and scrap quality belong in the carbon passport, not in a footnote.
