The processing step of making the said products comprises:
1, raw material is selected; 2, raw material process control; 3, check screening; 4, batching; 5, mix; 6, fusing; 7, calendering; 8, annealing; 9, check; 10, take up; 11, check; 12, packing; 13, warehouse-in.
In the aforesaid method step, 1, raw material is selected; 2, raw material process control; 3, check screening; 4, batching; 5, mix; 6, fusing; 7, calendering; 8, annealing; It is critical step.
In above-mentioned processing step:
(1) consider energy ultrawhite figured glass main raw material composition silica sand silicon content height and to the particular requirement of iron level composition, therefore when quality optimization was implemented in ore dressing, strict its machining process of control made lower the reaching of content of iron select requirement for use.
(2) fusing production technique: in each material combination process, pay attention to and control its chemical undulating quantity of variable in each raw material composition, strictly add the content of cerium oxide, make the ability that sees through that under reliable and stable state, realizes ultraviolet blocking-up light by this amount.Evenly mix the humiture that keeps certain after accurately disposing by automatic weighing system, melting under 1600 degree high temperature then, adjust temperature control again at the 1200-1250 degree, make the overflow port metal level reach 80-110mm. temperature 1180-1200 degree and enter the calendering operation.
