Nneɛma Titiriw a Ɛwɔ Hɔ

1. Ultra-ahotew a ɛkorɔn

(1) Eyi ne ade titiriw a ɛsen biara. Carbon a ɛyɛ pintinn a ɛwɔ flake graphite a ɛho tew kɛse-mu no taa yɛ Kɛse sen anaasɛ ɛyɛ pɛ 99.9%, nneɛma a ɛkɔ soro-awiei betumi adu Kɛse anaasɛ ɛyɛ pɛ 99.95%, Kɛse sen anaasɛ ɛyɛ pɛ 99.99%, anaasɛ ɛboro saa mpo.

(2) Ultra-nsõ a ɛba fam: nea ɛne ahotew a ɛkorɔn hyia no yɛ efĩ a ɛba fam koraa, mpɛn pii no Ennu anaasɛ ɛne 0.1% yɛ pɛ, nsõ a ɛwɔ soro-grade betumi ayɛ<0.01%.

(2) The advantage of large flakes: The value of large flakes is often in retaining a larger sheet diameter size (usually>150 mesh / 100μm, anaa nea ɛsõ sen saa mpo te sɛ +80 mesh, +50 mesh). Flakes akɛse wɔ mfaso pii wɔ conductive network adansi, lubrication ne graphene ahosiesie denam ntrɛwmu so.
