Budada Graphite waa dahabka ku jira beerta warshadaha waxayna ka ciyaartaa door weyn meelo badan. Waxaan marar badan maqlay kelmad ka hor in budada graphite ay tahay xalka ugu fiican si looga hortago daxalka qalabka. Macaamiil badan ayaan fahmin sababta. Maanta, tifaftiraha graphite Furuite waa qof walba. Si faahfaahsan u sharax sababta ay sidaas u leedahay:
Tilmaamaha tayada sare leh ee budada graphite waxay si dhakhso ah u noqdaan xalka ugu fiican si looga hortago daxalka qalabka.
1. U adkaysta heerkul sare oo cayiman. Heerkulka isticmaalka budada graphite waxay kuxirantahay noocyada kala duwan ee walxaha impregnation. Tusaale ahaan, graphite impregnated phenolic wuxuu u adkeysan karaa 170-200 ° C. Haddii qadar ku habboon oo xabagta silikoon lagu daro garaafka impregnate, waxay u adkeysan kartaa ilaa 350 ° C; marka phosphoric acid lagu shubo kaarboon iyo graphite, way u adkeysan kartaa Si loo hagaajiyo caabbinta oksaydhka ee kaarboon iyo graphite, heerkulka dhabta ah ee hawlgalka waa la kordhin karaa.
2. Heerarka kulaylka oo aad u fiican. Budada graphite sidoo kale waxay leedahay kulaylka wanaagsan. Waa shay aan bir ahayn oo xajintiisa kulaylkeedu uu ka sarreeyo kan birta, isagoo marka hore ka galay agabka aan birta ahayn. Dareenka kuleylku waa 2 jeer ka birta kaarboonka iyo 7 jeer ka birta aan-daawaalka ahayn. Sidaa darteed, waxay ku habboon tahay in loo isticmaalo qalabka wareejinta kulaylka.
3. Iska caabin daxalka oo aad u fiican. Noocyo kala duwan oo kaarboon ah iyo graphite waxay leeyihiin iska caabin aad u wanaagsan oo daxalka u ah dhammaan uruurinta hydrochloric acid, phosphoric acid iyo hydrofluoric acid, oo ay ku jiraan warbaahinta fluorine-ka ku jirta. .
4. Dusha sare ma fududa in la dhiso. "Affinity" ee u dhexeeya budada garaafka iyo inta badan warbaahinta waa mid aad u yar, sidaas darteed wasakhdu ma fududa in lagu dhejiyo dusha sare. Gaar ahaan loo isticmaalo qalabka uumiga iyo qalabka crystallization.
Sharaxaada sare waxay ku siin kartaa faham qoto dheer oo ku saabsan budada graphite. Qingdao Furuite Graphite waxay ku takhasustay habaynta iyo soo saarista budada garaafka, garaafka flake iyo alaabada kale. Waa lagugu soo dhawaynayaa inaad soo booqato warshada si aad hagis u hesho.
