ʻO ka pauka Micro Graphite

1. Huahana Hua

ʻO ka Graphite Micro pauda he mea hoʻoheheʻe graphite ultrafine i hoʻomākaukau ʻia mai ka graphite kūlohelohe kiʻekiʻe a i ʻole ka graphite artificial ma o nā kaʻina hana pololei e like me ka ʻohi ʻana, ka paʻi ʻana, a me ka hoʻomaʻemaʻe. Aia kona waiwai nui i ka ho'onui 'ana i ka pono o ka graphite's layered crystal structure ma o ka micro particle size optimization, ka mea e hui ai i ka conductivity maikaʻi, lubricity, high temperature resistance, and chemical stability, a hiki ke hoʻokō i ke koi no ka "hoʻomaʻemaʻe a me ka hana" o nā mea pauka ma nā kahua ʻoihana kiʻekiʻe -hope.

3. Core Hiʻona o ka Huahana

(1) -Maikaʻi ʻAiʻi Nui a me ka Māhele Kaulike

Hiki ke hoʻomalu ʻia ka nui o ka ʻāpana (D50) i loko o 1-10 μm (hiki ke hoʻopili ʻia i ka 100nm-5 μm ultrafine kikoʻī), me kahi kikoʻī liʻiliʻi liʻiliʻi (Span ʻoi aʻe a i like paha me 0.8), ʻaʻohe mea agglomeration, a maʻalahi hoʻi e hoʻopuehu i ka matrix, e hōʻoia i ka hana mau o ka huahana hopena.

(2) Maʻemaʻe kiʻekiʻe a me nā haumia haʻahaʻa

Loaʻa i ka Graphite Micro pauda ka maʻiʻo kalapona paʻa o ʻoi aku ma mua a i ʻole like me 99.5% (me nā kikoʻī -hopena kiʻekiʻe e hōʻike ana i kahi maʻiʻo kalapona paʻa o ʻoi aʻe ma mua a i like paha me 99.95%) a me ka maʻiʻo lehu ʻoi aʻe ma mua a i ʻole like me 0.5% (me nā kikoʻī ultrafine e hōʻike ana i kahi maʻiʻo o ka lehu o lalo a i ʻole 0.1%). ʻAʻole ia i nā mea haumia ʻino e like me ka sulfur a me ka phosphorus, i mea e pale aku ai i ka haumia i nā hiʻohiʻona noi a i ʻole ke keʻakeʻa ʻana i ka hana me lākou.

(3) Nā Pono Kino a me Kemika maikaʻi loa

Conductivity: Volume resistivity ʻAʻole i like a i ʻole like me 10 Ω·cm, hiki ke hoʻohana ʻia ma ke ʻano he mea hoʻopihapiha hoʻopihapiha e hoʻonui ai i ka conductivity mea;

Lubrication: Mohs hardness 1-2, friction coefficient I lalo a like paha me 0.15, hiki ke pani i nā lubricants metala i nā hiʻohiʻona lubrication aila ʻole;

Kūleʻa wela kiʻekiʻe: Hiki ke kū i nā mahana ma luna o 3000 degere i ke kinoea inert, ʻaʻole heheʻe a oxidize, a he haʻahaʻa haʻahaʻa o ka hoʻonui wela (2-5 × 10⁻⁶/ degere);

Paʻa kemika: Kūʻē i ka waika, alkali, a me nā mea hoʻoheheʻe kūlohelohe, kūpaʻa i ka pH 2-12 kaiapuni, a ʻaʻole e pane me ka hapa nui o nā mea kemika.

(4) Hiki ke hoʻololi i ka hana maikaʻi

He maikaʻi ke kahe ʻana o ka pauka (angle o ka hoʻomaha ʻAʻole i like me ka 35 degere), maʻalahi e hui pū me nā substrate e like me resin, rubber, metala pauka, a me nā mea ʻē aʻe, ʻaʻole e hōʻino i ke ʻano kumu o ka substrate. Hiki ke hana like ʻole ʻia ma o nā kaʻina hana e like me ka compression molding, injection molding, and coating.

 

 

4. Nā Wahi noi nui

(1) ʻOihana Lubrication

Ma keʻano he lubricant maloʻo i hoʻohuiʻia i nā mea mechanical e like me nā bearings, gears, valves;

No ka hoʻomākaukau ʻana i nā uhi lubricating paʻa (e laʻa, lubrication no nā lako makani makani, nā ʻāpana aerospace);

Hoʻohana ʻia ma ke ʻano he ʻaila lubricating/grease additive e hoʻomaikaʻi i ke ola lubrication a me ka hoʻololi ʻana i nā kūlana hana koʻikoʻi.

(2) Mahele ʻEhuka Hou

ʻO ka mea hoʻoheheʻe electrode ʻinoʻino ʻo Lithium: Hoʻomaikaʻi i ka lawe ʻana o nā mea electrode ʻino (e laʻa, graphite, silicon{2}}mea hoʻokumu ʻia), hoʻemi i ka pale ʻana i loko, hoʻonui i ka hoʻoiho ʻana-pono a me ke ola pōʻai;

ʻO ka uhi ʻana o ka pā bipolar cell fuel: Hoʻonui i ka conductivity a me ke kūpaʻa ʻino o nā pā bipolar, e hōʻemi i ke kūpaʻa pili.

(3) ʻOihana Hoʻopaʻa a me ka Inika

ʻO nā pale hoʻoheheʻe: Hoʻohana ʻia no ka papahele anti{0}}static, nā pale pale electromagnetic, nā ʻāpana ʻāpana uila;

ʻO ka uhi pale wela kiʻekiʻe: Hoʻohana ʻia no ka uhi ʻana i nā paia o loko o nā paila a me nā kiln e hoʻonui ai i ke kūpaʻa wela kiʻekiʻe a me ke kūpaʻa ʻana;

Inika kūikawā: Hoʻomākaukau i ka ʻīnika conductive (e laʻa, nā kaapuni uila maʻalahi, nā inoa RFID) e hōʻoia i ka hoʻokele paʻa ma hope o ka paʻi ʻana.

(4) Metallurgy and Refractory Materials

Metallurgical pale slag: Hoʻokumu i kahi kiʻiʻoniʻoni wai i ka wā e hoʻolei mau ana, hoʻokaʻawale i ka ea, lubricates i ka billet, a hōʻemi i nā hemahema o ka ʻili;

Pilikia Refractory/pale pale pale: Hoʻomaikaʻi i ka pale wela kiʻekiʻe a me ke kūpaʻa haʻalulu wela o nā mea refractory, i hoʻohana ʻia i nā mea wela kiʻekiʻe e like me ke kila a me nā kiln aniani.

(5) Mea Hana Uila a me ka pololei

Mea hoʻopili uila: Hoʻohui ʻia e like me nā mea hoʻopiha wela/conductive i nā mea hoʻopihapiha epoxy resin e hoʻomaikaʻi i ka maikaʻi o ka hoʻopau ʻana i ka wela;

Hoʻomaʻamaʻa pololei: Hoʻohana ʻia no ka hoʻomaʻamaʻa maikaʻi ʻana i nā wafers silicon semiconductor a me ke aniani aniani, e hōʻemi ana i ka ʻili o ka ʻili (a hiki i ka Ra ʻoi aʻe ma mua o 0.01 μm).
