Abstract

Secara praktis material karet untuk produk barang teknik memerlukan sejumlah bahan lain sebagai bahan tambahan yang mampu meningkatkan kemampuan proses, nilai karakteristik teknis dan memperpanjang waktu pakai. Bahan filler digunakan untuk meningkatkan karateristik teknis terkait dengan karakteristik karet. Salah satu filler yang sering diaplikasikan adalah silika, namun dalam bentuk teraktivasi. Beberapa penelitian menunjukan bahwa filler silika mampu mempengaruhi karakteristik seperti tensile strength, abrasion and tear resistance. Penggunaan filler silika pada balon peluncur kapal juga meningkatkan kinerja wet traction, dan wear resistance serta mengurangi dampak rolling resitance. Untuk mengaplikasikan silika kuarsa sebagai filler karet maka perlu mengaktivasi permukaan silika kuarsa antara lain dengan cara nanosizing atau memodifikasi permukaan silika melapisi dengan silane-69 atau PEG-4000. Saat ini produk silika lokal yang dihasilkan belum memenuhi spesifikasi silika berukuran sub mikron seperti yang dibutuhkan oleh pasar, umumnya produksi silika lokal berukuran ≥ 30 μm. Oleh karena itu utilisasi kapasitas produksi industri silika lokal belum maksimal, baru 50%. Dengan adanya sentuhan teknologi diharapkan dapat memaksimalkan potensi silika lokal.

Abstract

Practically rubber material for engineering goods requires a number of other ingredients as additives that can improve the ability of the process, the value of the technical characteristics and extend the lifetime. Filler material is used to improve the technical characteristics related to the characteristics of the rubber. One of the frequently applied filler is silica, but in the activated form. Several studies have shown that the silica filler capable of affecting characteristics such as tensile strength, abrasion and tear resistance. The use of silica filler on the balloon launcher ships also improves wet traction performance and wear resistance and reduce the impact of rolling resitance. To apply as a quartz silica filler rubber it is necessary to activate the surface of silica quartz, among others, by the way nanosizing or modify the silica surface with silane coat-69 or PEG- 4000. Currently local silica products produced not meet the specifications of sub- micron sized silica as required by the market, local silica production generally sized ≥ 30 lm. Therefore, industrial production capacity utilization is not maximized local silica, 50% new. With the touch technology is expected to maximize the potential of local silica.
