Abstract
本实用新型是一种内壁涂层的荧光灯管，涉及荧光灯领域，为了解决现有技术中黑色钠汞齐产生较多，灯的流明输出减小，流明维持率差的问题，我们用纳米二氧化钛的水稀释液材料对灯管内壁进行涂层，与灯管内壁形成内为灯管内壁玻璃，外为二氧化钛涂层的膜层结构，涂层厚度一般为0.8－1.3μm，选用的纳米二氧化钛材料的粒为10－80nm，由于纳米二氧化钛具有化学性质稳定，与基料相容性好，全面屏蔽等特点，与现有技术中用氧化铝涂层比较，钠原子难以通过热扩散而跑到荧光粉颗粒的表面和汞原子反应，黑色钠汞齐大大减少，从而流明维持率比普通的氧化铝涂层增加了6－8％，大大提高的灯的寿命。
Description
技术领域
本发明涉及荧光灯管领域，特别涉及一种内壁涂层的荧光灯管。
背景技术
限于目前我国的经济技术水平，我国制造紧凑型荧光灯管用的玻管材料的价格虽然较低，但品质较差品质较差主要表现在两个方面：一是含钠量较高，二是玻管的光致黑化严重，随着荧光灯的紧凑化，灯管的管壁负载进一步提高，灯管的工作温度也不断提高，玻管温度的提高加速了玻璃中钠离子的热扩散。这些钠离子将从玻璃内部扩散到玻管的内表面，并和那里的电子复合，形成中性的钠原子。在玻管内壁形成的钠原子又将通过热扩散而跑到荧光粉颗粒的表面，并在荧光粉颗粒的表面处和汞原子反应，生成黑色的钠汞齐。在荧光粉颗粒表面生成的黑色钠汞齐一方面将吸收辐照到荧光粉颗粒表面波长为253.7nm的激发紫外线、从而使荧光粉颗粒不能受到充分的激发；另一方面，在荧光粉颗粒表面的黑色钠汞齐将使灯的流明输出减小。由上面的分析可知，玻璃中的钠元素是使灯的流明维持率下降的主要因素之一，但现在普遍使用的氧化铝内壁涂层的效果并不很理想。
发明内容
为了解决现有技术中用氧化铝涂层，黑色钠汞齐产生较多，使灯的流明输出减小，流明维持率差的问题，我们提供的技术方案是用纳米二氧化钛水稀释液材料对灯管内壁进行涂层，使二氧化钛涂层[1]与灯管内壁玻璃[2]形成的膜层结构。二氧化钛涂层厚度为一般为0.8-1.3μm，纳米二氧化钛材料的粒径为10-80nm，最好10-50nm。由于纳米二氧化钛具有化学性质稳定，无刺激性，无致敏，与基料相容性好，作用时间长，全面屏蔽、粒子超细均匀，分散性优良等特点，与现有技术中用氧化铝涂层比较，钠原子难以通过热扩散而跑到荧光粉颗粒的表面，在荧光粉颗粒的表面处和汞原子反应，黑色钠汞齐大大减少，因此用纳米二氧化钛材料涂层的荧光灯管的流明维持率比普通的氧化铝涂层增加了6-8％，从而大大提高的灯的寿命。其中二氧化钛材料的粒径为10-80nm，最好是10-50nm，用纯水稀到4-9％，如需要悬浮液中可加入一定量的分散剂和粘接剂。均匀涂后烘干并可重复涂，涂层厚度L为0.8-1.3μm。测量方法可用容易操作的如下方法，虽不太精确，但很实用。选灯管不同位置的可被测量的灯管碎片5-10片，测出各块表面积S、弄下纳米二氧化钛材料测重量W、比重F(不考虑当加入一些助剂时引起比重的稍微变化)、据此测出涂层厚度L，即Ln＝Wn/Sn*F(n为1-10)，最终L＝L1+L2+…L10/10。当然也可用已知的先进的光学或电子或化学方法.(如请国家有色金属质量监督检验中心测试)
附图说明：
图1为最一般的荧光灯示意图；图2为灯管上最普通的一点A处放大示意图，其中1为二氧化钛涂层，2为灯管内壁玻璃，3为荧光粉。

实施例二：选50nm二氧化钛用纯水稀到5％对灯管内壁涂层(如图2)，烘烤固化，重复涂一次，形成内为灯管内壁玻璃2，外为二氧化钛涂层1的膜层结构，其它工艺照旧如上粉等。与常用的氧化铝涂层比较2000h的流明维持率增加了7.4％，涂层厚度经测为1.0μm。
实施例三：选80nm二氧化钛用纯水稀到6％对灯管内壁涂层(如图2)，固化，形成内为灯管内壁玻璃2，外为二氧化钛涂层1的膜层结构，其它工艺照旧如上粉等。与常用的氧化铝涂层比较2000h的流明维持率增加了7％，涂层厚度经测为0.8μm。
