\"agen<\/p>\n

Bahan penutup yang juga disebut fluks penutup<\/a>, digunakan sebagai lapisan permukaan selama proses pemurnian dan pemeliharaan suhu aluminium serta paduan aluminium. Bahan ini dapat mengisolasi aluminium cair dari udara guna mengurangi kerugian akibat pembakaran dalam proses peleburan serta mencegah penguapan dan oksidasi selama proses pemeliharaan suhu. Selain itu, bahan ini juga memiliki efek pembersihan terhadap oksida berminyak pada permukaan bahan aluminium yang masuk ke dalam aluminium cair, sehingga mengurangi tingkat pencemaran pada aluminium cair.<\/p>\n

Mengapa menggunakan fluks penutup?<\/h3>\n

Aluminium adalah unsur logam yang sangat reaktif. Dalam proses elektrolisis, peleburan, dan pemindahan, aluminium cair atau paduan aluminium dengan mudah menyerap gas sehingga membentuk inklusi terak, lapisan oksida, pori-pori, kerongongan, dan cacat lainnya (terutama hidrogen dan oksigen), yang pada akhirnya menurunkan kemurnian aluminium cair atau paduan aluminium. Kualitas produk seperti kemurnian produk dan ketahanan korosi juga memengaruhi kinerja pemrosesan aluminium dan paduan aluminium. Oleh karena itu, dalam proses peleburan aluminium dan paduan aluminium, diperlukan penggunaan agen penutup untuk mencegah pembakaran oksidatif dan penguapan logam cair, serta untuk meningkatkan kemurnian dan kualitas produk aluminium atau paduan aluminium.<\/p>\n

Saat ini, masih sedikit penelitian mengenai aliran penutup<\/a>, dan berikut ini adalah masalah-masalah utamanya:
\n1. Fluks pelapis tidak dapat menghasilkan gas pelindung untuk secara aktif melindungi logam aluminium cair (yaitu, aluminium cair atau paduan aluminium cair).
\n2. Fluks penutup tidak dapat membentuk lapisan pelindung yang sangat padat pada permukaan cairan aluminium atau cairan paduan aluminium, sehingga efek pelindungnya kurang baik.
\n3. Penguapan air pada bahan penutup belum sepenuhnya selesai, dan kelembapan dalam fluks penutup mudah bereaksi dengan aluminium, sehingga menyebabkan peningkatan kadar gas dalam cairan aluminium.
\n4. Saat ini, bahan penutup umumnya tidak memiliki kemampuan untuk menghilangkan terak.<\/p>\n

Fitur-fitur agen penutup:<\/h2>\n

Bubuk putih dengan titik leleh rendah yang terdiri dari garam klorida dan garam fluorida ini memiliki kelancaran aliran yang baik dan dapat dengan cepat meleleh untuk membentuk lapisan pelapis saat ditaburkan pada permukaan aluminium cair.<\/p>\n

Dosis fluks pelapis untuk aluminium<\/a>:<\/h2>\n

Gunakan 0,5\u20131,0 kg per meter persegi permukaan aluminium cair.<\/p>\n

Petunjuk:
\nSetelah aluminium dilebur hingga membentuk permukaan cair, fluks penutup ditaburkan di atas permukaan aluminium cair sesuai dengan takarannya, dan permukaan aluminium cair setelah penghilangan terak juga harus ditutupi dengan jumlah fluks yang sama.<\/p>","protected":false},"excerpt":{"rendered":"
