该问题的解决办法之一,就是一点也不使用铅,甚至在餐具的熔块釉中也不使用,我通常推荐这一做法。
滤杯,玻璃烧结滤头,铝制夹,硅胶塞,罩杯,四氟抽气盘。
结果表明,含NO.2玻璃料的烧渗铝电极试样显现出低的接触电阻和良好的抗老化特性。
1·The glass is coated with a solid white fritted finish with some degree of transparency.
玻璃表面有一层白色烧结的涂层并有一定的透明度。
2·The end of the injection tube is provided with a dispersion device such as a porous plug or fritted glass.
注射管的末端提供有分散装置例如多孔塞或烧结玻璃。
3·Similarly the cantilevered canopies of metal clad steel structure and fritted pattern glass merge the wave forms into a series of repeating flowing elements.
同样,悬臂式檐金属包钢结构和烧结多孔玻璃汇合而成的波浪也呈现着层层流动要素。
