Graphite poda yekuisa chisimbiso zvinhu

Micronized graphite inoshandiswa zvakanyanya mundima yekuisa chisimbiso, kunyanya kushandisa zvimiro zvayo seyepamusoro tembiricha kuramba, self-kuzora, kugadzikana kwemakemikari uye kusimba. Sechinhu chakakosha, Graphite poda yezvinamiso inowanzoiswa kune simba kana static sealing munzvimbo yakakwirira-yetembiricha, yakakwirira-kudzvanywa kana kuita ngura.

Technical Parameters

Parameter	Typical Value/Chinodiwa	Test Standard
Particle Size	1–50 μm (Iyo yakatsetseka, ndiyo iri nani kuita chisimbiso)	ISO 13320
Density	1.0–1.8 g/cm³	ASTM D3800
Compressibility	15–30%	GB/T 5409
Leakage Rate	Zvisingasviki kana kuenzana ne 1×10⁻⁴ mbar·L/s (Gasi - inosunga)	ISO 15848

Ongorora: Zvigadzirwa zvinotsigira zvakasarudzika.

Core zvakanakira kuiswa chisimbiso

(1) Kudzivirirwa kwekushisa kwepamusoro: Inogona kushanda pa-200℃~3000℃(in non-oxidizing atmosphere), iyo iri nani kudarika rabha kana mapurasitiki ekuvharisa zvinhu.

(2) Self-kuzora: Iyo yakaturikidzana inoderedza friction coefficient (0.1~0.3) uye inoderedza kusapfeka kwezvikamu zvekunamira.

(3) Kemikari inertness: Inopikisa kune acids, alkalis uye organic solvents (kunze kwekusimba oxidizing media yakadai se concentrated nitric acid).

(4) Plasticity: Micronized poda iri nyore kuzadza nzvimbo dzisina kujairika uye kugadzira dense yekuisa chisimbiso.

(5) Electrical/thermal conductivity: Inokodzera kuvharisa zviitiko zvinoda kupera kupisa kana anti-static.

Mafomu ekuisa chisimbiso akajairika uye mamiriro ekushandisa

(1) Graphite poda yekuisa chisimbiso kurongedza Kuumbwa: Micronized graphite yakasanganiswa nesimbi waya uye fibers (yakadai secarbon fibers) uye yakatsikirirwa. Kuvharisa mavharuvhu, pombi shafts uye zvinokuchidzira (semuenzaniso, pombi dzemakemikari, maketani akakwirira-anoita tembiricha). Zvimiro: Kudzvinyirira kuramba kusvika ku20MPa, inoda kushandiswa negirizi kuderedza kutanga torque.

(2) Flexible graphite seals (yakawedzerwa graphite) Maitiro: Micronized graphite inoiswa acidified, inowedzerwa uye yobva yatsikwa mumagaskets, mahwendefa kana spiral maronda gaskets. Chishandiso: Static chisimbiso chepombi flanges, kupisa kunopisa uye injini silinda misoro. Zvimiro: Yakakwira rebound mwero (Kupfuura kana kuenzana ne40%), iyo inogona kubhadhara kusaenzana kwenzvimbo dzeflange.

(3) Zvinhu zvakaumbwa zvekuvharisa Graphite + simbi: Senge graphite-copper composite zvinhu, zvinoshandiswa pakukwirira{3}}kuspeed bearing chisimbiso. Graphite + polymer: Zvakadai sePTFE-graphite composite zvinhu, zvine zvese zvinoramba corrosion uye kuderera kwakaderera.

Kushandisa: Anti-kubata kwepamusoro-mabhaudhi ekupisa nemajoini ane thread.

Particle saizi inogadziriswa kuti isangane nekuparadzira zvinodiwa mumajasi, macomposites, nezvimwe.

• High carbon, yakaderera madota inovimbisa kuchena kwemagetsi, simba idzva, kuderedza kusvibiswa.

• Pakati penzvimbo chaiyo uye tap density balance dispersibility uye formability, yakakodzera kugadzirira slurry, compression molding, nezvimwewo.

• Low resistivity inogonesa yakanakisa conductivity, yakanaka kune conductive additives uye electrodes. Chisimbiso Performance Test Standards uye Parameters.
