(1) Optimise the production formula, choose easily dispersible additives to replace the existing additives, increase the application of dispersants, homogenizers and other processing aids to improve the dispersion performance of various additives.
(2) mixing rubber using a two-stage refiner production process, a mixing to increase the temperature, so that the moisture in the raw materials and volatile components of the full volatility of the rubber after parking and then two mixing, temperature control in the addition of sulphur and accelerator temperature range, to avoid scorching time is short or scorching occurs.
(3) Plasticising, one mixing, two mixing, out of each process to strictly control the parking time of semi-finished products. Allow a variety of additives to fully diffuse, improve the uniformity of the rubber, and at the same time is conducive to the recovery of stress and strain under mechanical action.
(4) The rubber should be evenly heated, through the cutter, falling disc, pounding rubber and other operations to make the rubber mixing uniform. Adopt the operation mode of separate hot melting rubber supply and moulding to improve the smoothness of the surface of the moulded rubber.
(5) Extrude the rubber material by extrusion process, and there is no more air hiding on the surface of the moulded rubber material.
