ʻO ka graphite he allotrope o carbon, he aniani hoʻololi ma waena o nā kristal atomika, nā kristal metala a me nā kristal mole. organic acids.Used like antiwear agent and lubricating material, making crucible, electrode, dry battery, pencil lead.The scope of graphite detection: natural graphite, dense crystalline graphite, flake graphite, cryptocrystalline graphite, graphite powder, graphite pepa, expanded graphite, graphite emulsion, hoʻonui graphite, pālolo graphite a conductive graphite pauka, etc.
1. kiʻekiʻe wela kū'ē: ka hehee ai o ka graphite he 3850 ± 50 ℃,ʻoiai ma hope o ka ultra-kiʻekiʻe wela wela arc, he uuku loa ka poho kaumaha, thermal hoonui coefficient he uuku loa. . Ma 2000 ℃, pālua ka ikaika o ka graphite.
2. conductive, thermal conductivity: ka conductivity o ka graphite he hoʻokahi haneli mau manawa kiʻekiʻe ma mua o ka maʻamau non-metallic ore.The thermal conductivity o ke kila, hao, kēpau a me nā mea metala. kiʻekiʻe wela, graphite i loko o ka insulation;
3. lubricity: ka lubrication hana o ka graphite e pili ana i ka nui o ka graphite flake, flake, friction coefficient ka mea uuku, ka lubrication hana maikai;
4. kemika paʻa: graphite i ka lumi wela i maikai kemika paʻa, kaʻakika kū'ē, alkali kū'ē a me ka organik solvent corrosion kū'ē;
5. plasticity: maikaʻi ka graphite toughness, hiki ke ʻoki ʻia i loko o kahi ʻāpana lahilahi;
6. thermal ha'alulu kū'ē: graphite i ka lumi wela ke hoʻohana 'ia hiki ke ku drastic hoʻololi i ka wela me ka poino ole, wela mutation, ka leo o ka graphite loli iki, aole e poha.
1. haku mele 'ana: carbon carbon, moisture, haumia, etc.;
2. Ka ho'āʻo hana kino: paʻakikī, lehu, viscosity, fineness, particle size, volatilization, specific gravity, specific surface area, melting point, etc.
3. ʻO ka hoʻāʻo ʻana i nā waiwai mechanical: ikaika tensile, brittleness, hoʻāʻo kulou, hoʻāʻo tensile;
4. ka ho'āʻo hoʻokō kemika: ka pale wai, ka lōʻihi, ka ʻakika a me ke kūpaʻa alkali, ka pale ʻana i ka corrosion, ka pale ʻana i ka wā, ka pale wela, etc.
5. Nā mea ho'āʻo ʻē aʻe: conductivity uila, thermal conductivity, lubrication, kemika kūpaʻa, thermal shock resistance
