Nanopoudre de graphite : au cours du processus de production, la taille des particules de la nanopoudre de graphite est contr\u00f4l\u00e9e dans la plage du nanom\u00e8tre par des moyens technologiques sp\u00e9cifiques. Afin de r\u00e9pondre \u00e0 vos exigences sp\u00e9cifiques, nous pouvons poursuivre le traitement de la nanopoudre de graphite. Nous ajustons avec pr\u00e9cision la taille des particules afin de garantir qu'elles r\u00e9pondent aux besoins d'une vari\u00e9t\u00e9 de sc\u00e9narios d'application. Jinsun peut fournir de la nanopoudre de graphite de haute puret\u00e9 avec un maillage de 50 \u00e0 5500 mesh.<\/p>\n

Avantages des nanopoudres de graphite<\/h2>\n

En g\u00e9n\u00e9ral, la nano-poudre de graphite se pr\u00e9sente sous forme de poudre. Elle pr\u00e9sente des avantages \u00e9vidents.<\/p>\n

Bonne stabilit\u00e9 thermique<\/strong><\/p>\n

Il r\u00e9siste \u00e0 l'oxydation \u00e0 haute temp\u00e9rature.<\/p>\n

Propri\u00e9t\u00e9s chimiques stables<\/strong><\/p>\n

Il r\u00e9siste \u00e0 la corrosion acide et alcaline.<\/p>\n

Activit\u00e9 de surface \u00e9lev\u00e9e<\/strong><\/p>\n

Vous pouvez l'utiliser dans la peinture, la r\u00e9sine, etc.<\/p>\n

Conductivit\u00e9, lubrification et adsorption \u00e9lev\u00e9es<\/strong><\/p>\n

Il peut former une liaison chimique sur la surface m\u00e9tallique du nano graphite r\u00e9sistant et presque non abrasif. En suspension dans l'huile lubrifiante, un grand nombre de nano graphites r\u00e9duisent la r\u00e9sistance et le frottement, scellent l'autolubrification. Il s'agit d'un mat\u00e9riau de lubrification solide id\u00e9al.<\/p>\n

La poudre de graphite peut notamment former un rev\u00eatement de nanoparticules, qui pr\u00e9sente de bonnes propri\u00e9t\u00e9s de barri\u00e8re, de r\u00e9sistance \u00e0 l'usure et de r\u00e9sistance \u00e0 la corrosion.<\/p>\n

Par ailleurs, la nano-poudre de graphite contient des nanoparticules de graphite dont la taille est de l'ordre du nanom\u00e8tre, ce qui lui conf\u00e8re des propri\u00e9t\u00e9s exceptionnelles en mati\u00e8re de lubrification, d'adsorption, etc.<\/p>\n

Types de nanopoudres de graphite<\/h2>\n

Nanopoudre de graphite, carbone<\/a> est g\u00e9n\u00e9ralement de l'ordre de 98%-99%, voire plus. Il existe principalement les types suivants de nanopoudre de graphite.<\/p>\n

Poudre g\u00e9n\u00e9rale de nano graphite<\/p>\n

Son D50<400nm, D100<1000nm, lui permet d'\u00eatre largement utilis\u00e9 dans l'industrie chimique, la lubrification de l'acier et d'autres domaines.<\/p>\n

Poudre de graphite nanom\u00e9trique de tr\u00e8s petite taille<\/p>\n

Le D50 est plus petit, a une surface sp\u00e9cifique plus \u00e9lev\u00e9e et de meilleures performances. Vous pouvez souvent l'utiliser dans des domaines sp\u00e9ciaux o\u00f9 les exigences en mati\u00e8re de performance des mat\u00e9riaux sont \u00e9lev\u00e9es. Par exemple, les mat\u00e9riaux nanocomposites haut de gamme, les batteries \u00e0 haute performance, etc.<\/p>\n

Utilisations de la nanopoudre de graphite<\/h2>\n

La nano-poudre de graphite est largement utilis\u00e9e. Voici quelques domaines d'application courants.<\/p>\n

Domaine \u00e9lectronique et \u00e9lectrique :<\/strong><\/p>\n

En tant qu'additif conducteur, il peut \u00eatre ajout\u00e9 aux composants \u00e9lectroniques et aux rev\u00eatements conducteurs, batterie<\/a> mat\u00e9riaux, etc. Pour am\u00e9liorer de mani\u00e8re significative leurs propri\u00e9t\u00e9s conductrices, contribuant ainsi \u00e0 am\u00e9liorer les performances et la stabilit\u00e9 des \u00e9quipements \u00e9lectroniques.<\/p>\n

Champ \u00e9nerg\u00e9tique :<\/strong><\/p>\n

Dans les batteries lithium-ion, les supercondensateurs, etc., il peut \u00eatre utilis\u00e9 comme mat\u00e9riau d'\u00e9lectrode ou comme additif conducteur. Pour am\u00e9liorer l'efficacit\u00e9 de la charge et de la d\u00e9charge des batteries et leur dur\u00e9e de vie. Dans les pile \u00e0 combustible<\/a>Vous pouvez l'utiliser pour pr\u00e9parer des catalyseurs de haute performance afin d'am\u00e9liorer l'efficacit\u00e9 et la stabilit\u00e9 de la pile \u00e0 combustible.<\/p>\n

Industrie des machines :<\/strong><\/p>\n

En tant que lubrifiant solide, vous pouvez l'ajouter \u00e0 l'huile lubrifiante, \u00e0 la graisse, et l'utiliser pour la lubrification des pi\u00e8ces m\u00e9caniques. Pour r\u00e9duire le frottement et l'usure, am\u00e9liorer l'efficacit\u00e9 m\u00e9canique.

Dans le rev\u00eatement anticorrosion, il permet d'am\u00e9liorer la propri\u00e9t\u00e9 anticorrosion et la r\u00e9sistance aux intemp\u00e9ries du rev\u00eatement.<\/p>\n

A\u00e9rospatiale :<\/strong><\/p>\n

En composites carbone-carbone<\/a>Il peut am\u00e9liorer la r\u00e9sistance \u00e0 l'ablation et la r\u00e9sistance \u00e0 la chaleur du composite. Le rev\u00eatement de nanoparticules peut \u00e9galement am\u00e9liorer les performances du mat\u00e9riau.<\/p>","protected":false},"excerpt":{"rendered":"
