Berbasis alumina filter busa keramik<\/a> Pelat untuk penyaringan dan pemurnian aluminium cair mendominasi pasar. Pelat tersebut menggunakan fosfat sebagai pengikat suhu tinggi, yang dapat memenuhi persyaratan umum untuk pemurnian dan penyaringan aluminium cair. Namun, terdapat risiko tersembunyi berupa korosi dan pencemaran lingkungan. Unsur magnesium dalam paduan aluminium berkadar magnesium tinggi bereaksi dengan aluminium fosfat pada suhu 600\u2013800\u00b0C, sehingga merusak bahan pengikat suhu tinggi pada pelat filter keramik dan merusak struktur pelat filter keramik tersebut. Dalam kasus yang parah, pelat filter akan rusak. Potongan-potongan yang terlepas akan mencemari cairan aluminium, sekaligus menghasilkan magnesium fosfida dan aluminium fosfida, yang akan mengalami reaksi hidrolisis saat terpapar kelembapan atau air di udara, sehingga melepaskan gas fosfin yang beracun dan mudah terbakar, serta mencemari lingkungan. Karena koefisien ekspansi termal yang tinggi dan modulus elastisitas alumina yang besar, tegangan termal menjadi sangat besar selama pemanasan awal yang cepat, sehingga retakan mudah terjadi, yang mengakibatkan \u201ckeruntuhan lempengan\u201d selama penggunaan, sehingga menyebabkan terhentinya proses pengecoran atau masuknya terak ke dalam produk.<\/p>\n

Mengingat situasi di atas, setelah bertahun-tahun melakukan penelitian, Adtech telah berhasil mengembangkan jenis baru pelat filter keramik berbahan busa yang tahan korosi dan ramah lingkungan, yang tidak mengandung fosfor (Filter busa keramik bebas fosfor<\/strong><\/a>), dengan menggunakan garam boron sebagai pengikat suhu tinggi untuk mencegah korosi unsur magnesium dalam paduan, sekaligus menerapkan pelat saringan anti-korosi yang memiliki koefisien muai rendah. Secara keseluruhan, hal ini mencegah erosi aluminium dan magnesium, secara signifikan mengurangi tegangan termal yang timbul selama pemanasan awal yang cepat, serta memiliki ketahanan yang tinggi terhadap guncangan termal. Baru-baru ini, uji produksi skala kecil telah berhasil diselesaikan. Produk ini memiliki kekuatan tekan yang tinggi pada suhu kamar (1,2 MPa), kekuatan lentur yang tinggi pada suhu kamar (0,8 MPa), serta ketahanan terhadap guncangan termal yang baik, sehingga dapat memenuhi kebutuhan filtrasi dan pemurnian paduan aluminium dengan kandungan magnesium tinggi.<\/p>\n
