(3) Abɔde ne Nnuru Su a Ɛkyɛn So

Conductivity: Volume resistivity Ennu anaasɛ ɛne 10 Ω·cm yɛ pɛ, wobetumi de adi dwuma sɛ conductive filler de ama nneɛma conductivity ayɛ kɛse;

Srade: Mohs hardness 1-2, friction coefficient Ennu anaasɛ ɛne 0.15 yɛ pɛ, betumi asi dade srade ananmu wɔ srade tebea horow a ngo nnim mu;

Ɔhyew a ɛkorɔn a ɛko tia: Etumi gyina ɔhyew a ɛboro digrii 3000 ano wɔ mframa a ɛnyɛ adwuma mu, ɛnnwene anaasɛ ɛnyɛ oxidize, na ɛwɔ ɔhyew ntrɛwmu nsusuwii a ɛba fam (2-5 × 10−6/℃);

Nnuru a ɛyɛ den: Ɛko tia acid, alkali, ne organic solvent corrosion, ɛyɛ den wɔ pH 2-12 tebea mu, na ɛne nnuru dodow no ara nyɛ adwuma.

(4) Nneɛma a Wɔde Di Dwuma a Wotumi Sesa

Powder no wɔ flowability pa (angle of repose<=35℃), ɛnyɛ den sɛ wɔde bɛfra substrates te sɛ resin, rɔba, dade powder, ne nea ɛkeka ho, na ɛnsɛe mfitiase nhyehyɛe a ɛwɔ substrate no mu. Wobetumi ayɛ ho adwuma wɔ akwan horow so denam akwan horow te sɛ compression molding, injection molding, ne coating so.

 

 

4. Mmeae Titiriw a Wɔde Di Dwuma

(1) Nnwuma a Wɔde Srade Yɛ

Sɛ́ srade a ɛyɛ dry a wɔde ka mfiridwuma mu nneɛma te sɛ bearings, gears, valves ho;

Sɛ wɔbɛsiesie sradeɛ a ɛyɛ den a wɔde kata so (sɛ nhwɛsoɔ no, sradeɛ a wɔde yɛ mframa ahoɔden mfiri, ahunmu nneɛma a wɔde kata so);

Wɔde di dwuma sɛ ngo/srade a wɔde ka ho na ama srade nkwa nna atu mpɔn na wɔatumi ayɛ nsakrae wɔ adwumayɛ tebea horow a emu yɛ den mu.

(2) Ahoɔden Dwumadibea Foforo

Lithium battery negative electrode conductive agent: Ɛma electrode nneɛma a ɛnyɛ papa (sɛ nhwɛso no, graphite, silicon-gyina nneɛma so), ɛtew battery mu ahoɔden a ɛko tia so, ɛma charge-discharge efficiency ne cycle nkwa nna yɛ kɛse

Fuel cell bipolar plate coating: Ɛma conductivity ne corrosion resistance a bipolar plates no yɛ kɛse, ɛtew contact resistance so.

(3) Nneɛma a Wɔde Kata Nneɛma So ne Ink Nnwuma

Conductive coatings: Wɔde di dwuma ma anti-static fam, electromagnetic shielding coatings, ɛlɛtrɔnik component shell coatings;

Nneɛma a wɔde kata so a ɛko tia ɔhyew a ɛkɔ soro: Wɔde kata nsuo a wɔde yɛ nsuo ne fononoo mu afasuo so na ama ɔhyew a ɛkɔ soro a ɛko tia ne nea ɛtumi nsɛe no yɛ kɛseɛ;

Ink soronko: Siesie ink a ɛma nsu fa mu (sɛ nhwɛso no, ɛlɛtrɔnik amansin a ɛyɛ mmerɛw, RFID tags) de hwɛ hu sɛ nsu a ɛkɔ mu no gyina pintinn bere a wɔatintim ink awie no.

(4) Dade ne Nneɛma a Ɛmma Ogya Ntumi Nhyew

Metallurgical protective slag: Ɛyɛ nsu slag film bere a ɛkɔ so tow, ɛtew mframa, sra billet no, na ɛtew sintɔ ahorow a ɛwɔ soro no so;
