2020年9月19日 One of the methods of producing coated sands is the hot coating. In this process granulated phenol–formaldehyde, novolak type resin of a melting temperature app. 80–100 °C, is applied. 2–3.5% of this resin (versus a mass of sand and in dependence on the application) is added to a sand heated up to a resin melting temperature (120–150 °C).

2020年11月19日 billions of grains can be consistently and uniformly coated with a resin film only 1/10 the thickness of a human hair. Because angular grains are rough and jagged, about 25% more resin is required for adequate coating than for rounded grains (see Fig. 2). More resin means more gas, more cost, and poorer coated sand flowability.
