Warqada garaafka waxa ay ka samaysan tahay garaafka kaarboonka kaarboonka sareeyo iyada oo loo marayo daawaynta kiimikaad iyo balaadhinta heerkulka sare. Muuqaalkeedu waa siman yahay, iyada oo aan lahayn xumbo cad, dildilaac, laalaab, xoqin, wasakh iyo cillado kale. Waa maaddada aasaasiga ah ee soo saarista shaabadaha graphite ee kala duwan. Waxaa si weyn loo isticmaalaa in shaabadeynta firfircoon iyo mashiinnada, tuubooyinka, bambooyin iyo valves ee awoodda korontada, batroolka, kiimikaad, qalabaynta, mashiinada, dheeman iyo warshadaha kale. Waa qalab cusub oo lagu xidho oo lagu beddelo shaabadihii dhaqanka sida caag, fluoroplastics iyo asbestos. .
Tilmaamaha waraaqaha graphite waxay inta badan ku xiran yihiin dhumucdeeda. Waraaqaha graphite oo leh tilmaamo iyo dhumucyo kala duwan ayaa leh adeegsiyaal kala duwan. Waraaqaha graphite waxa loo qaybiyaa waraaqo garaafeed dabacsan, warqad graphite ah oo khafiif ah, warqad garaafeed shaabadaysan, warqad heerkulbeeg leh, warqad garaafeed, iwm. Noocyada kala duwan ee waraaqaha garaafiga ah Waxay ka ciyaari kartaa doorkeeda saxda ah ee dhinacyada warshadaha kala duwan.
6 sifada warqada garaafka:
1. Fududeynta habaynta: Waraaqaha Graphite-ka waxa loo kala qaybin karaa cabbiro kala duwan, qaabab iyo dhumucyo kala duwan, waxaana la bixin karaa looxyo fidsan oo la jarjaray, dhumucduna waxay u dhaxaysaa 0.05 ilaa 1.5m.
2. Heerkulka sare ee caabbinta: heerkulka ugu badan ee xaashida graphite wuxuu gaari karaa 400 ℃, ugu yaraanna wuxuu ka hoosayn karaa -40 ℃.
3. Heerarka kulaylka sare: Xakamaynta kuleylka ugu badan ee diyaaradda ee warqad graphite waxay gaari kartaa 1500W / mK, caabbinta kulaylkuna waa 40% ka hooseeya kan aluminium iyo 20% ka hooseeya kan naxaasta.
4. Dabacsanaanta: Waraaqaha garaafka si fudud ayaa loogu samayn karaa laminates leh birta, lakabka daboolan ama cajalad laba dhinac ah, taas oo kordhisa dabacsanaanta naqshadeynta waxayna yeelan kartaa koollo xagga dambe ah.
5. Iftiinka iyo dhumucnaanta: Waraaqaha garaafka 30% way ka fudud yihiin aluminium isku cabbir iyo 80% ka fudud naxaasta.
6. Fududeynta isticmaalka: Weelka kulaylka garaafka garaafka ayaa si habsami leh loogu dhejin karaa meel kasta oo siman oo qalloocan.
Markaad kaydinayso warqad graphite, u fiirso labadan arimood ee soo socda:
1. Bey'adda Kaydinta: Waraaqaha garaafyada ayaa aad ugu habboon in la dhigo meel qalalan oo siman, mana soo bandhigto qorraxda si looga hortago in la tuujiyo. Inta lagu jiro habka wax soo saarka, waxay yareyn kartaa isku dhaca; waxa ay leedahay heer go'an oo conductivity ah, markaa marka loo baahdo in la kaydiyo, waa in laga fogeeyaa isha tamarta. silig koronto.
2. Ka hortagga jebinta: Waraaqda graphite waa mid aad u jilicsan qaab ahaan, waxaan u gooyn karnaa si waafaqsan shuruudaha, si looga hortago in ay jabaan inta lagu jiro kaydinta, kuma habboona laalaab ama foorarsi iyo isku laabasho xagal yar. Alaabooyinka waraaqaha graphite ee guud waxay ku habboon yihiin goynta go'yaal.
