🦺Как делают

Арамид · Ароматический полиамид: бронепакеты, горячая фильтрация, замена асбеста.

Making Арамид is a chain: feedstock, conversion (DuPont 1965 Kwolek), forming, heat, finish, install.

Skip a step and the properties chapter is describing a different object.

Шаги процесса

01 Feedstock

Ore, monomer, fibre, mineral or scrap that can legally become Арамид.

02 Conversion

DuPont 1965 Kwolek

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.

Маршруты

Primary

Virgin route around United States.

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.

Жёсткие пределы

Envelope

Melting/softening does not melt; decomposes ~500 °C; conductivity low radial; fibre anisotropic.

Environment

Moisture, UV, chlorides, alkalis or oxygen — pick the one that actually kills Арамид.

Code

Fire class inherently FR vs commodity PA is a starting letter, not a wall rating.

Process energy and scrap quality belong in the carbon passport, not in a footnote.
