JIUNN WEI can provide mixing formulations for many popular RAL& Pantone colors. However, due to application and glass variables thorough tests should be made under local manufacturing conditions before commencing full production.
圳偉可按RAL 和PANTONE 色號調色, 但是因為測試條件和玻璃本身的不同, 在大量使用前請以當地制造條件為準.
Firing 燒結
The LF23000 series can be fired through most conventional tempering and heat strengthening cycles.可以適合于大部分的鋼化, 熱硬化爐
Furnace Temperature: 640-720℃ (1180-1330℉)加熱溫度640~720度
Firing Time: 100-300 seconds (Depending on glass thickness)加熱時間100~300秒,根據玻璃厚度不同.
Peak Glass Temperature: 630-650℃(1160-1200℉) 高峰溫度630~650度.
The gloss level can vary slightly depending on firing time and temperature.油墨的色澤可通過調節燒結溫度,時間來做稍微的調整.
Higher Temperature: More Gloss溫度高一點可以使色澤亮一點
Longer Firing: More Gloss時間長一點也可使色澤亮一點

While the colors are stable across a wide firing range the burn-out of organic media can create a destabilizing chemical environment. This can be prevented by providing adequate ventilation to ensure an oxygen rich environment is maintained within the furnace.
有機溶劑在燃燒時可能會使爐內化學環境不穩定, 為避免污染可以通過對加熱爐通風,送氧來改善.
Application使用

Heavy Metal Free
All industries, including those that the glass industry supplies, are moving towards the elimination of heavy metals from products and processes.
The demand for heavy metal free is being generated from a number of sources for a variety of reasons.所有工業包括玻璃工業都在朝袪除重金屬的方向努力. 很多領域已經要求無重金屬
��*Improve Health and Safety in the workplace.改善工作環境的健康與衛生
��*Reduce the cost of heavy metal waste disposal for glass decorators.減少對有重金屬的玻璃裝飾品的廢棄物的處理費用
��*Create consumer satisfaction with I green’ glass products. 制造客戶滿意的 “綠色”玻璃產品
��*Remove heavy metals from waste streams when glass is eventually disposed of.當玻璃較終被處理時, 減少的廢物中的重金屬

The heavy metals lead and cadmium have traditionally been used for ceramic and glass decoration. Lead oxide has always been a major component in the frit that the major constituent of a glass enamels. These frits are manufactured by the smelting of lead oxide with silica, boron and other minerals and alkali metals.
The presence of lead in the frit imparts many desirable properties on the glass enamel. 鉛, 鎘傳統上一直被用來做玻璃的裝飾, 氧化鉛一直都是玻璃粉內較主要的成分, ( 而玻璃粉也是玻璃釉料的主要的成分) 玻璃粉是由氧化鉛, 硅, 硼以及其它金屬和堿金屬熔溶而成. 鉛在玻璃粉力起著非常重要的角色.
��*Low softening temperature降低熔點
��*High gloss增加亮度
��*Good strength and chemical resistance 提高耐化學性耐機械性能
��*Low cost 降低成本
