Chiyambi cha njira zopangira mafakitale ndi kugwiritsa ntchito graphite yowonjezereka

Graphite yowonjezereka, yomwe imadziwikanso kuti vermicular graphite, ndi crystalline compound yomwe imagwiritsa ntchito njira zakuthupi kapena zamakemikolo kuti iphatikize ma reactants osakhala ndi kaboni kukhala zinthu zachilengedwe za nanocarbon zophatikizika ndi graphite komanso kuphatikiza ndi ma network a carbon hexagonal network pamene ikusunga kapangidwe ka Graphite. Sikuti imangosunga zinthu zakuthupi ndi zamakemikolo za graphite, monga kukana kutentha kwambiri, kukana dzimbiri, kutuluka kwa neutron, X-ray ndi gamma-ray kwa nthawi yayitali. Ilinso ndi zinthu zabwino kwambiri zakuthupi ndi zamakemikolo, monga friction coefficient yochepa, kudzipaka mafuta bwino, kuyendetsa magetsi ndi kutentha, komanso anisotropy. Kuphatikiza apo, chifukwa cha kuyanjana pakati pa zinthu zophatikizika ndi graphite, graphite yowonjezereka imawonetsa zinthu zatsopano zomwe graphite yoyera ndi zinthu zophatikizika zilibe, ndipo imagonjetsa kufooka ndi kukana mphamvu kwa graphite yachilengedwe. Okonza graphite otsatirawa a Furuite akugawana njira zoyambira zopangira mafakitale ndi kugwiritsa ntchito graphite yowonjezereka:

1. Njira zopangira zomwe zimagwiritsidwa ntchito kwambiri m'makampani

①Kusungunuka kwa mankhwala

Ubwino: Kuthira mankhwala ophera tizilombo ndi njira yomwe imagwiritsidwa ntchito kwambiri komanso yodziwika bwino m'mafakitale. Chifukwa chake, ili ndi ubwino woonekeratu, ukadaulo wokhwima komanso mtengo wotsika.

Kuipa: Cholumikizira nthawi zambiri chimakhala ndi sulfuric acid yambiri, yomwe imadya asidi wambiri. Pali kuipitsidwa kwa mpweya woipa wa Sox pakupanga, ndipo zotsalira mu chinthucho zimawononganso zida zopangira.

②Kusungunuka kwa ma elekitiroma

Monga mankhwala okosijeni, ndi njira imodzi yodziwika bwino yopangira graphite yowonjezereka.

Ubwino: Palibe chifukwa chowonjezera ma oxidant amphamvu, monga ma asidi amphamvu, ndipo zomwe zimachitika zimatha kuyendetsedwa posintha magawo monga mphamvu yamagetsi ndi magetsi. Zipangizo zopangira ndi zosavuta, kuchuluka kwa kapangidwe kake ndi kwakukulu, electrolyte siiipitsidwa, ndipo ikhoza kugwiritsidwanso ntchito.

Zoyipa: Kukhazikika kwa chinthu chopangidwa ndi zinthu zopangidwa ...

2. Makampani akuluakulu opanga zinthu ndi mphamvu zopangira zinthu

Kupanga zinthu zopangidwa ndi graphite m'dziko langa kwakula kuyambira pachiyambi mpaka kufika pa opanga oposa 100, ndipo kupanga kwake pachaka ndi pafupifupi matani 30,000, ndipo kuchuluka kwa msika kuli kochepa. Komanso, opanga ambiri makamaka ndi odzaza zisindikizo zotsika mtengo, zomwe sizigwiritsidwa ntchito kawirikawiri m'magalimoto ndi magetsi a ndege za nyukiliya. Komabe, ndi chitukuko cha ukadaulo wapakhomo, chiwerengero cha zinthu zapamwamba chidzawonjezeka pang'onopang'ono.

3. Kufunika kwa msika ndi kulosera kwa zipangizo zotsekera

Pakadali pano, grafiti yowonjezereka imagwiritsidwa ntchito makamaka ngati zipangizo zotsekera magalimoto, monga ma gasket a silinda, ma gasket olowera ndi otulutsa mpweya, ndi zina zotero. Zipangizo zotsekera grafiti yowonjezereka m'dziko langa zimagwiritsidwa ntchito kwambiri ngati zodzaza zotsekera. Pakadali pano, grafiti yowonjezereka yokhala ndi mpweya wochepa yapangidwa, zomwe zingathandize kuchepetsa kwambiri mtengo wopanga grafiti yowonjezereka, motero m'malo mwa asbestos pamlingo waukulu ndikuwonjezera kufunikira. Kumbali inayi, ngati zipangizo zotsekera za pulasitiki, mphira ndi zitsulo zitha kusinthidwa pang'ono, kufunikira kwa pachaka kwa zipangizo zotsekera grafiti yowonjezereka kudzakhala kwakukulu.

Mu makampani opanga magalimoto, gasket iliyonse ya silinda ya mutu wa galimoto, gasket yolowetsa mpweya ndi gasket yotulutsa utsi imafunikira pafupifupi 2 ~ 10kg ya grafiti yowonjezera, ndipo magalimoto 10,000 aliwonse amafunikira matani 20 ~ 100 a grafiti yowonjezera. Makampani opanga magalimoto ku China alowa munthawi ya chitukuko chofulumira. Chifukwa chake, kufunikira kwa chaka chilichonse kwa zinthu zotsekera grafiti yowonjezera kudziko langa kudakali kopanda tsankho.
