Graphite powder parad saray materyales ya panag-seal

Say micronized graphite et mabetbet ya uusaren ed panag-seal, ya uusaren to ray kablian to a singa say atagey ya resistensya ed petang, self-lubrication, chemical stability tan compressibility. Bilang manunan materyales, say graphite powder parad saray materyales ya panag-seal et mabetbet ya iyaaplika ed dinamiko odino ag-onkikiwas ya panag-seal ed atagey-temperatura, atagey-pressure odino makapasinagem iran kaliberliber.

Saray manunan bentaha ed panagselyo

(1) Atagey ya resistensya ed petang: Nayarin mankimey ed -200℃~3000℃(diad ag-oxidizing ya atmospera), ya mas maong nen saray materyales ya pang-seal ya goma o plastik.

(2) Self-lubrication: Say layered structure et mamapaabeba ed friction coefficient (0.1~0.3) tan mamapaabeba ed pakasulong na saray sealing parts.

(3) Chemical inertness: Resisti ed saray asido, alkali tan organikon solvent (likud ed mabiskeg ya oxidizing media a singa say concentrated nitric acid).

(4) Plasticity: Say micronized powder et mainomay ya panoen iray ag-regular ya tapew tan manporma na makapal ya sealing layer.

(5) Electrical/thermal conductivity: Matukoy parad saray senaryo na panag-seal ya mankaukolan na heat dissipation odino anti-static.

Saray kaslakan a porma na panagtatak tan saray senaryo na aplikasyon

(1) Graphite powder parad panag-seal na packing Komposisyon: Micronized graphite ya inlaok ed metal ya alambre tan lanot (singa say carbon fibers) tan in-press. Aplikasyon: Dinamikon panagselyo na saray balbula, pump shaft tan agitator (alimbawa, chemical pump, high-temperature reaction kettles). Features: Pressure resistance ya anggad 20MPa, kaukolan ya usaren ed grasa pian nabawasan so starting torque.

(2) Flexible graphite seals (expanded graphite) Proseso: Say micronized graphite et na-acidify, napalaknab insan i-press ed saray gasket, plato odino spiral wound gaskets. Aplikasyon: Ag-onkikiwas ya panagselyo na saray flange na tubo, saray heat exchanger tan saray ulo na silindro na makina. Features: Atagey ya rebound rate (Mas baleg o mipara ed 40%), ya makabawi ed agpantatalosan na flange surfaces.

(3) Composite sealing materials Graphite + metal: Singa say graphite-copper composite materials, ya uusaren parad high-speed bearing sealing. Graphite + polymer: Singa say PTFE-graphite composite materials, ya walaan na resistensya ed corrosion tan abeban friction.

(4) Proseso na Dry sealing coating: Ipalapag so micronized graphite ed sakey a binder insan i-spray o i-brush ed tapew na sealing.

Aplikasyon: Anti-seize na high-temperature bolts tan threaded joints.

Say kabaleg na partikulo et nayarin i-adjust pian nasumpal so pankaukolan na dispersion ed saray coating, composite, tan arum nira.

• Say atagey a carbon, abeban dapol so mamaseguro na kalinisan parad saray elektroniko, balon enerhiya, tan mamapaabeba ed saray dutak.

• Say kaslakan ya espisipikon surface area tan tap density et manbalanse ed dispersibility tan formability, ya matukoy parad panagparaan na slurry, compression molding, tan arum nira.

• Say abeban resistivity et mamapawala na ekselentin konduktibidad, ya maabig parad saray konduktibon additives tan electrode. Saray Estandarte tan Parametro na Pansukimat ed Panag-seal.
