In powder production methods, there are currently wet granulation, dry granulation, melting granulation, pre-dispersion granulation.The pre - dispersed masterbatch product has dispersibility and fluidity.The dispersibility of chemical additives in masterbatch directly affects the stability of mechanical properties of vulcanized products.At present, the rheological test instruments include rotary rheometer, torsi rheomerter, drop-ball viscometer lan rhheometer kopillary tong .}} {Saliyane tes kinerja karet kerajinan vulpliced
Miturut Shenyang sunnyjoint ,, sawetara negara maju sisih kulon duwe penting kanggo perlindungan lingkungan lan kontrol teknis sing paling awal, lan ing akhir taun 80-anake, ana ing taun-taun 80-anake, ana ing taun-taun 80 Sawetara, Kajaba iku, ing babagan produk produk manca industri yaiku komplek produk sing komplek, multi-fungsi ing riset industri, amarga sawetara perusahaan, amarga sawetara perusahaan, amarga ana masalah paling gedhe ing industri, nanging masalah paling gedhe ing industri iki yaiku produk kasebut Rega dhuwur, nanging kinerja biaya ora dhuwur, sing ana gandhengane karo perusahaan domestik kanggo promosi kinerja dhuwur masterbatch ing titik iki ora bisa ngerteni metode ilmiah masterbatch sing disusupi .}
Taun iki, masterbatch pre-besspersed Rubber duwe standar industri sing relevan, kanggo ndhukung pangembangan industri sing gegandhengan .
