Description
Technical Field
The invention belongs to the technical field of glass processing, and particularly relates to a preparation method of lead-free and barium-free environment-friendly crystal glass.
Background
Lead oxide (PbO) and barium oxide (BaO) are common components in traditional crystals, and can improve the refractive index and the dispersion rate of glass. In the existing glass formula, the content of PbO and BaO in the glass component is increased in order to improve the refractive index and the dispersion ratio. When the lead crystal glass product is used, lead dissolved out in the process of using the product as a water utensil, a wine utensil and a tableware is very toxic and harmful to human health. The barium oxide introduced into the barium crystal which is widely developed at present also belongs to the high-toxicity oxides. The Europe and developed countries have limits on harmful elements such As Pb, Ba, As, Be, Cd, Hg, Sb, Se and Cr, and the development of a formula of lead-free barium-free environment-friendly crystal glass is imperative. Similar research reports exist in China, but the refractive index of the high-lead crystal is difficult to achieve under the condition of not adding lead and barium.
In the processing process of the crystal glass, large individual bodies in the raw materials of the glass need to be crushed and ground, the particles of the raw materials are smaller, the melting speed is higher in the subsequent melting step process, the melting effect is better, if the ground particles are too small, the particles are easy to scatter in the air and are easy to be inhaled into the lung by workers frequently when being collected, so that the lung is greatly damaged, meanwhile, strip-shaped or sheet-shaped blocks cannot smoothly pass through a conventional grinding machine and cannot enter a grinding area due to different sizes and shapes of the individual bodies of the raw materials, so that the materials cannot be processed in time, the waste of the materials is caused, or the raw material ratio is different to a certain degree due to the fact that part of large materials cannot be ground, so that the quality of a final product is poor, furthermore, generally, the equipment in the aspect has a larger individual structure and a larger occupied area, so that the walking range of workers is greatly reduced, and the workers are easily injured.
