Q:Chemical materials and additives needed for the production of glass

Production process of 1.3.1 glass1. Raw material pretreatment. The bulk raw materials (quartz sand, soda ash, limestone, feldspar, etc.) grinding, so that dry wet raw materialsDry, iron containing raw materials for iron removal, in order to ensure the quality of glass.2, batch preparation. According to the product, the composition of the mixture is slightly different. For example, ordinary float glass batch (calculated in accordance with 1 weight boxes of 50 kilograms), need to consume 33.55 kg of quartz sand, limestone, dolomite, 2.96 kg 8.57 kg 11.39 kg of soda, Glauber's salt 0.55 kg, 3.45 kg, 0.03 kg of feldspar powder etc..3, melting. The glass mixture is heated in a bath or crucible furnace at a high temperature (1550-1600 degrees) to form a liquid glass that is uniform, free of bubbles and conforms to the molding requirements.
