Abstract

Fabrikasi penyangga membran lorong jamak dengan bahan alumina dan kaolin menggunakan metode ektrusi untuk proses mikrofiltrasi telah dilakukan. Potensi penggunaan membran di berbagai aspek industri mendorong dilakukannya penelitian ini mengingat belum adanya industri membran dalam negeri. Penggunaan bahan utama alumina dan kaolin denga menambahkan  bahan imbuhan seperti CMC, Metosel, corn starch dan aquadest untuk menghasilkan massa keramik plastis. Pengujian keplastisan dilakukan sebagai petunjuk awal dilakukannya proses ektrusi. Faktor yang menetukan keberhasilan penyangga membran telah dapat diidentifikasi dan diselesaikan yaitu faktor geometri pada sepanjang cetakan, diameter cetakan pada bagian pembentukan suport minimal sama. Diameter pori yang dibentuk oleh pembentuk pori bergantung  pada diameter dari poreformer. Starch yang digunakan sebagai pembentuk pori pada percobaan ini menghasilkan diameter pori dengan rata-rata 10 mikron

Abstract

The fabrication of complex-shaped dense ceramic has been done by gel casting method. Alumina was used as raw material in this study. Alumina was mixed with methacrylamide (MAM) dispersant and Methylenebisacrylamide (MBAM) monomer with a certain ratio until the suspension has a good ability to flow. Ammonium persulphate (APS) as an initiator and Tetra-methylethylene diamine (TEMED) as catalyst were added to accelerate the polymerization reaction. The suspension was then poured into wax mold, stayed until harden and burned at 1300 oC. The results showed the minimum viscosity of suspension is obtained with 80% alumina content and addition of dispersant at 0.15% weight of alumina. The addition of APS and TEMED at 0.2% weight of monomer solution and the addition of PEG at 1 µl per gram alumina provided the best mechanical strength of green body at 61.29 kg/cm2 . Addition of PEG was used to overcome the problem of lamination due to oxidation reactions by air
