Sifat bubuk grafit dengan kemurnian tinggi<\/h2>\n

Ketahanan suhu tinggi dan konduktivitas termal<\/strong><\/p>\n

Titik leleh grafit adalah 3850 \u00b1 50\u00b0C, dan titik didih 4250\u00b0C. Koefisien ekspansi termal sangat kecil, yaitu 1,4\u00d710^-6\/K. Hal ini membuatnya mampu mengurangi kehilangan material pada suhu tinggi. Selain itu, konduktivitas termal bubuk grafit dengan kemurnian tinggi pada suhu kamar dapat mencapai 2,17\u00d710^6 W\/(cm-K), nilai ini dapat bervariasi karena metode pengukuran dan konversi satuan. Tetapi masih dapat menunjukkan konduktivitas termal bubuk grafit yang secara umum lebih unggul pada suhu kamar. Karena konduktivitas termal yang tinggi dan ketahanan suhu tinggi dari bubuk grafit, ia dapat dengan cepat mentransfer panas dan mengurangi akumulasi panas. Sementara itu bisa tetap stabil pada suhu tinggi.<\/p>\n

Listrik:<\/strong> Karena struktur kristalnya yang istimewa, grafit memiliki konduktivitas listrik yang baik. Semakin tinggi kemurnian grafit, semakin kecil ukuran partikelnya, semakin kuat konduktivitasnya. Dengan demikian, bubuk grafit dengan kemurnian tinggi kami mampu memberikan konduktivitas listrik yang sangat baik.<\/p>\n

Pelumasan:<\/strong> Serbuk grafit dengan kemurnian tinggi mengandung lebih sedikit pengotor, memberikan pelumasan yang lebih baik serta mengurangi gesekan dan keausan. Partikel grafit dengan kemurnian tinggi lebih cenderung membentuk lapisan pelumas yang seragam, sehingga mengurangi kontak antara permukaan mekanis. Semakin besar serpihannya, semakin kecil koefisien gesekannya, semakin baik performa pelumasannya.<\/p>\n

Stabilitas kimiawi:<\/strong> grafit<\/a> memiliki stabilitas kimia yang baik pada suhu kamar. Dan dapat menahan korosi asam, alkali dan pelarut organik.<\/p>\n

 <\/p>\n

Aplikasi bubuk grafit dengan kemurnian tinggi<\/h2>\n

Pelumas:<\/strong> Karena koefisien gesekan dan struktur lembarannya yang rendah, serbuk grafit sering digunakan sebagai pelumas kering, terutama di lingkungan bersuhu tinggi atau vakum tinggi. Orang menggunakannya secara luas dalam pelumasan komponen mekanis, seperti bantalan dan roda gigi.<\/p>\n

Industri metalurgi:<\/strong> Bubuk grafit<\/a> juga merupakan agen pereduksi yang umum digunakan dalam industri metalurgi. Ini membantu menghilangkan kotoran dalam logam dan meningkatkan kemurnian, kekerasan, dan kekuatan logam. Selain itu, ini juga merupakan aditif paduan untuk pembuatan baja<\/a> dan logam non-besi.<\/p>\n

Bahan tahan api:<\/strong> Beberapa jenis bubuk grafit dapat ditambahkan ke bahan tahan api untuk meningkatkan ketahanan terhadap api.<\/p>\n

Bahan pelepas cetakan dan cetakan:<\/strong> Selama pengecoran<\/a> proses, bubuk grafit bertindak sebagai lapisan isolasi. Ini mencegah logam menempel pada cetakan dan memastikan pelepasan yang mulus. Dalam pembuatan cetakan, ini juga bertindak sebagai agen pelepas yang umum.<\/p>\n

Bahan yang tahan korosi dan menyegel:<\/strong> Serbuk grafit juga umum digunakan dalam bahan penyegel. Seperti bubuk gran (menyegel minyak anti lengket). Orang banyak menggunakannya di kapal, pesawat terbang, lokomotif, dan permukaan pengikat logam mesin besar lainnya, bagian sambungan flensa segel dan anti lengket. Ketahanan korosi yang sangat baik memungkinkan grafit mempertahankan kinerja penyegelan yang efisien di lingkungan yang keras untuk waktu yang lama. Jadi mereka juga umum di industri kimia dan perminyakan.<\/p>\n

Industri ringan:<\/strong> Serbuk grafit adalah bahan pemoles dan bahan anti karat untuk pembuatan kaca dan kertas dalam industri ringan. Ini juga merupakan bahan baku yang sangat diperlukan untuk pembuatan pensil, tinta, cat hitam, tinta dan berlian sintetis, dll.<\/p>\n

Industri kimia:<\/strong> Orang-orang menggunakan bubuk grafit untuk membuat peralatan kimia seperti penukar panas dan tangki reaksi. Selain itu, grafit juga dapat digunakan sebagai pelumas pelepas untuk produksi katalis dalam industri pupuk.<\/p>\n

 <\/p>\n

Selain itu, serbuk grafit juga dapat digunakan sebagai bahan pigmen dan pelapis, pelumas dalam produksi kabel, dan untuk produksi ketahanan film karbon, cetakan kering konduktif. Secara umum, penggunaan serbuk grafit sangat luas, mencakup hampir semua bidang produksi industri.<\/p>","protected":false},"excerpt":{"rendered":"

Serbuk grafit dengan kemurnian tinggi adalah serbuk grafit dengan kemurnian (kandungan karbon) lebih dari 99,9%. Di bawah kondisi isolasi oksigen, titik leleh bubuk grafit berada di atas 3000\u00b0C, yang menjadikannya salah satu mineral yang paling tahan suhu. Terlebih lagi, bubuk grafit memiliki sifat kimia yang relatif stabil di bawah suhu kamar.<\/p>\n

Serbuk grafit dengan kemurnian tinggi dapat digunakan sebagai pelumas, elektroda, bahan tahan api, dan bahan komposit.<\/p>","protected":false},"featured_media":7200,"template":"","meta":[],"product_brand":[],"product_cat":[67],"product_tag":[],"class_list":{"0":"post-7199","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-graphite-material","8":"first","9":"instock","10":"shipping-taxable","11":"product-type-simple"},"yoast_head":"\nHigh
