Flux Butiran Aluminium<\/strong> digunakan untuk penghilangan terak pada aluminium dan paduan aluminium. Komponen utamanya adalah natrium klorida, kalium klorida, dan magnesium klorida. Komponen klorida menyumbang lebih dari 80%.
\nBerkat kepadatan optiknya, bahan ini dapat tersebar dengan baik di permukaan aluminium cair, namun fluks yang mengandung garam klorin hanya memiliki kemampuan terbatas dalam menyerap dan melarutkan terak. Bahan pemurnian ini bebas asap dan tidak beracun, sehingga dapat mengurangi polusi di bengkel pengecoran aluminium. Mengurangi dampak buruk terhadap kesehatan para pekerja.<\/strong><\/p>\n

Apabila kadar terak dan gas dalam lelehan aluminium dan paduan aluminium terlalu tinggi, hal itu akan sangat meningkatkan kemungkinan terjadinya cacat metalurgi seperti pori-pori dan inklusi pada slab.
\nHal ini pada gilirannya akan mengurangi kekuatan dan plastisitas bahan serta memengaruhi kualitas permukaan produk.
\nApabila kandungan natrium dalam paduan aluminium terlalu tinggi, lapisan adsorpsi cairan mudah terbentuk pada permukaan atau batas butir dendrit selama proses pengerjaan panas, yang mengakibatkan patahan getas pada paduan aluminium berkadar magnesium tinggi.
\nOleh karena itu, dalam proses peleburan aluminium dan paduan aluminium, terak, gas, serta logam alkali dalam cairan peleburan harus dihilangkan sebanyak mungkin. AdTech menyediakan bahan pengolah aluminium<\/a> untuk menghilangkan terak.<\/p>\n

\"Flux<\/p>\n

Menambahkan sedikit garam fluorida ke Alu Granulated Flux<\/strong> dapat meningkatkan penyerapan dan pelarutan fluks ke dalam terak, mempercepat pemisahan antara terak dan cairan aluminium, serta meningkatkan efektivitas proses pemurnian.
\nSediaan olahan bebas natrium yang terdiri dari fluoroaluminat kalium, fluorida kalsium, karbonat kalium, sulfat kalium, sulfat barium, klorida kalium, dan klorida aluminium anhidrat.
\nNamun, kepadatan barium sulfat cukup tinggi (4,50 g\/cm\u00b3), sehingga zat ini tidak mudah mengapung saat digunakan. Selain itu, barium sulfat dan kalsium fluorida juga mudah membawa unsur-unsur pengotor ke dalam logam cair paduan aluminium.<\/p>\n

Selain itu<\/strong>, sebagian besar komponen garam klorida yang terkandung dalam Alu Granulated Flux mudah menyerap kelembapan di udara, dan beberapa garam klorida (seperti magnesium klorida) biasanya terdapat dalam bentuk hidrat kristalin.
\nJika bagian air ini tidak dapat dihilangkan sepenuhnya, maka ketika fluks masuk ke dalam lelehan paduan aluminium, hal itu akan meningkatkan kadar hidrogen dalam lelehan paduan aluminium tersebut.
\nSaat ini, sebagian besar fluks paduan aluminium diproduksi melalui proses pencampuran mekanis sederhana dari berbagai komponen. Metode ini tidak dapat menghilangkan kelembapan sepenuhnya dari fluks tersebut.<\/p>\n

Untuk lelehan paduan aluminium yang memerlukan pengendalian ketat<\/strong> kadar gas dan kadar logam alkali; selain menggunakan nitrogen atau argon sebagai gas pemurnian, biasanya klorin yang lebih reaktif dan heksakloroetana juga diperlukan untuk pengolahan logam cair.
\nMeskipun klorin dan heksakloroetana memiliki efek pemurnian yang baik, keduanya berbahaya bagi kesehatan pekerja, peralatan, dan lingkungan, serta dapat mengancam nyawa dalam kasus-kasus yang parah.<\/p>\n

Penambahan fluks butiran aluminium ke dalam pabrik peleburan aluminium dapat meningkatkan kualitas hasil coran. Fluks ini dicampurkan sesuai dengan proses dan aplikasi tertentu. Fluks berfungsi untuk melindungi permukaan, mengolah endapan, membersihkan dinding tungku, membersihkan logam, menghidrogenasi, dan memurnikan kristal.<\/p>","protected":false},"excerpt":{"rendered":"
