1. Geleneksel uygulamalar<\/strong><\/p>\n

1) Refrakter malzemeler: Grafit ve \u00fcr\u00fcnleri, y\u00fcksek s\u0131cakl\u0131k dayan\u0131m\u0131 ve y\u00fcksek mukavemet \u00f6zelliklerine sahiptir. Esas olarak metalurji end\u00fcstrisinde grafit potalar yapmak i\u00e7in kullan\u0131l\u0131r. \u00c7elik \u00fcretiminde, grafit genellikle \u00e7elik k\u00fcl\u00e7eler i\u00e7in koruyucu bir madde olarak ve metalurjik f\u0131r\u0131nlar i\u00e7in astar olarak kullan\u0131l\u0131r.<\/p>\n

2) \u0130letken malzemeler: elektrik end\u00fcstrisinde elektrotlar, f\u0131r\u00e7alar, karbon \u00e7ubuklar, karbon t\u00fcpler, c\u0131va pozitif ak\u0131m cihazlar\u0131n\u0131n pozitif elektrotlar\u0131, grafit y\u0131kay\u0131c\u0131lar, telefon par\u00e7alar\u0131, televizyon resim t\u00fcpleri i\u00e7in kaplamalar vb. yapmak i\u00e7in kullan\u0131l\u0131r.<\/p>\n

3) A\u015f\u0131nmaya dayan\u0131kl\u0131 ya\u011flama malzemesi: Grafit, makine end\u00fcstrisinde genellikle ya\u011flay\u0131c\u0131 olarak kullan\u0131l\u0131r. Ya\u011flama ya\u011f\u0131, y\u00fcksek h\u0131z, y\u00fcksek s\u0131cakl\u0131k ve y\u00fcksek bas\u0131n\u00e7 ko\u015fullar\u0131nda kullan\u0131lamazken, grafit a\u015f\u0131nmaya dayan\u0131kl\u0131 malzemeler, ya\u011flama ya\u011f\u0131 olmadan 200 ila 2000 \u2103 s\u0131cakl\u0131kta y\u00fcksek kayma h\u0131zlar\u0131nda \u00e7al\u0131\u015fabilir. A\u015f\u0131nd\u0131r\u0131c\u0131 ortamlar\u0131n ta\u015f\u0131nmas\u0131na y\u00f6nelik bir\u00e7ok ekipman, piston kaplar\u0131, s\u0131zd\u0131rmazl\u0131k halkalar\u0131 ve yataklar yapmak i\u00e7in yayg\u0131n olarak grafit malzemeleri kullan\u0131r ve \u00e7al\u0131\u015fma s\u0131ras\u0131nda ya\u011flama ya\u011f\u0131 eklemeleri gerekmez. Grafit em\u00fclsiyonu ayr\u0131ca bir\u00e7ok metal i\u015fleme (tel \u00e7ekme, boru \u00e7ekme) i\u00e7in iyi bir ya\u011flay\u0131c\u0131d\u0131r.<\/p>\n

4) Grafit iyi kimyasal stabiliteye sahiptir. \u00d6zel olarak i\u015flenmi\u015f grafit, korozyon direnci, iyi termal iletkenlik ve d\u00fc\u015f\u00fck ge\u00e7irgenlik \u00f6zelliklerine sahiptir. Is\u0131 e\u015fanj\u00f6rleri, reaksiyon tanklar\u0131, kondenserler, yanma kuleleri, absorpsiyon kuleleri, so\u011futucular, \u0131s\u0131t\u0131c\u0131lar, filtreler, Pompa ekipmanlar\u0131 \u00fcretiminde yayg\u0131n olarak kullan\u0131lmaktad\u0131r. Petrokimya end\u00fcstrisinde, hidrometalurjide, asit bazl\u0131 \u00fcretimde, sentetik elyafta, ka\u011f\u0131t yap\u0131m\u0131nda ve bir\u00e7ok metal malzemeden tasarruf edebilen di\u011fer end\u00fcstriyel sekt\u00f6rlerde yayg\u0131n olarak kullan\u0131lmaktad\u0131r.<\/p>\n

5) D\u00f6k\u00fcm, kum d\u00f6k\u00fcmhanesi, kal\u0131p ve y\u00fcksek s\u0131cakl\u0131kl\u0131 metalurjik malzemeler: Grafitin k\u00fc\u00e7\u00fck termal genle\u015fme katsay\u0131s\u0131 ve so\u011fuk ve \u0131s\u0131daki h\u0131zl\u0131 de\u011fi\u015fimlere dayanma kabiliyeti nedeniyle cam kal\u0131p olarak kullan\u0131labilir. Grafit kullan\u0131ld\u0131ktan sonra, hassas boyutlara ve y\u00fcksek y\u00fczey p\u00fcr\u00fczs\u00fcz ve bitmi\u015f \u00fcr\u00fcn oran\u0131na sahip d\u00f6k\u00fcmler elde etmek i\u00e7in demirli metaller kullan\u0131labilir. , \u0130\u015flenmeden veya az i\u015flenmeden kullan\u0131labilir, b\u00f6ylece \u00e7ok fazla metal tasarrufu sa\u011flan\u0131r. Semente karb\u00fcr \u00fcretimi ve di\u011fer toz metalurjisi prosesleri, s\u0131k\u0131\u015ft\u0131rma kal\u0131plar\u0131 ve sinterleme i\u00e7in porselen tekneler yapmak i\u00e7in genellikle grafit malzemeleri kullan\u0131r.

Ayr\u0131ca, grafit, grafit \u0131s\u0131 yal\u0131t\u0131m levhalar\u0131 ve tabanlar\u0131, y\u00fcksek s\u0131cakl\u0131\u011fa dayan\u0131kl\u0131 f\u0131r\u0131n borular\u0131, \u00e7ubuklar, levhalar, \u0131zgara \u0131zgaralar\u0131 ve di\u011fer bile\u015fenlerin vakumla eritilmesi i\u00e7in de kullan\u0131labilir.<\/p>\n

6) Atom enerjisi end\u00fcstrisinde ve ulusal savunma sanayinde kullan\u0131l\u0131r: Grafit, atom reakt\u00f6rlerinde kullan\u0131lan iyi bir n\u00f6tron moderat\u00f6r\u00fcne sahiptir. Uranyum-grafit reakt\u00f6r\u00fc, yayg\u0131n olarak kullan\u0131lan bir t\u00fcr atomik reakt\u00f6rd\u00fcr. G\u00fc\u00e7 olarak kullan\u0131lan n\u00fckleer reakt\u00f6rdeki yava\u015flama malzemesi y\u00fcksek erime noktas\u0131na, stabiliteye ve korozyon direncine sahip olmal\u0131d\u0131r. Grafit, yukar\u0131daki gereksinimleri tam olarak kar\u015f\u0131layabilir. Atomik reakt\u00f6rlerde kullan\u0131lan grafit olarak safl\u0131k gereksinimleri \u00e7ok y\u00fcksektir ve safs\u0131zl\u0131k i\u00e7eri\u011fi d\u00fczinelerce PPM’yi ge\u00e7memeli, \u00f6zellikle bor i\u00e7eri\u011fi 0,5 PPM’den az olmal\u0131d\u0131r.

7) Grafit ayr\u0131ca kazan\u0131n kirlenmesini de \u00f6nleyebilir. \u0130lgili birimler taraf\u0131ndan yap\u0131lan testler, belirli bir miktar grafit tozunun (ton su ba\u015f\u0131na yakla\u015f\u0131k 4 ila 5 gram) eklenmesinin kazan y\u00fczeyinin kirlenmesini \u00f6nleyebilece\u011fini g\u00f6stermi\u015ftir. Ayr\u0131ca metal bacalarda, \u00e7at\u0131larda, k\u00f6pr\u00fclerde ve borularda grafit kaplama korozyon ve paslanmay\u0131 \u00f6nleyebilir.<\/p>\n

8) Grafit kur\u015fun kalem, pigment<\/a> ve cila maddesi olarak kullan\u0131labilir. Grafit \u00f6zel olarak i\u015flendikten sonra ilgili end\u00fcstriyel sekt\u00f6rlerde kullan\u0131lmak \u00fczere \u00e7e\u015fitli \u00f6zel malzemeler yap\u0131labilmektedir.<\/p>\n

Do\u011fal grafitin \u00f6zelliklerine ek olarak, bu \u00fcr\u00fcn ayn\u0131 zamanda onu ideal bir s\u0131zd\u0131rmazl\u0131k malzemesi yapan \u00f6zel esneklik ve elastikiyete sahiptir. Petrokimya, atom enerjisi ve di\u011fer end\u00fcstriyel alanlarda yayg\u0131n olarak kullan\u0131lmaktad\u0131r.<\/p>\n

2) Grafit ayr\u0131ca hafif sanayide cam ve ka\u011f\u0131t yap\u0131m\u0131 i\u00e7in bir parlat\u0131c\u0131 ve pas \u00f6nleyici maddedir ve kur\u015fun kalem, m\u00fcrekkep, siyah boya, m\u00fcrekkep, sentetik elmas ve elmas \u00fcretimi i\u00e7in vazge\u00e7ilmez bir hammaddedir.<\/p>\n

Modern bilim ve teknolojinin ve end\u00fcstrinin geli\u015fmesiyle birlikte, grafitin uygulama alan\u0131 hala geni\u015flemektedir. Y\u00fcksek teknoloji alan\u0131nda yeni kompozit malzemeler i\u00e7in \u00f6nemli bir hammadde haline gelmi\u015f ve \u00fclke ekonomisinde \u00f6nemli bir rol oynamaktad\u0131r.<\/p>\n","protected":false},"excerpt":{"rendered":"
