摘要:
A conductive material for use in interior coating of a cathode ray tube (CRT), which includes an aqueous dispersion medium containing potassium silicate and a dispersing agent; and graphite particles. The potassium silicate of the aqueous dispersion medium has a silicon dioxide (SiO 2 ) to potassium oxide (K 2 O) mole ratio in the range of 4.5:1 to 6:1, and is prepared by adding hydrosilica gel to a potassium silicate aqueous solution having a SiO 2 to K 2 O mole ratio less than 4.5:1. When the conductive material, which uses potassium silicate dispersed in an aqueous dispersion medium with a SiO 2 :K 2 O mole ratio in the range of 4.5:1 to 6:1, as a binder, is applied to form a conductive layer on the funnel of a CRT, adheviseness of the conductive layer markedly increases. Use of the potassium silicate as a binder decreases the amount of gas released during a hot-evacuation process, and thus shortens evacuation time.

一种用于阴极射线管(CRT)的内部涂层的导电材料,其包括含有硅酸钾和分散剂的水性分散介质; 和石墨颗粒。 水性分散介质中的硅酸钾具有4.5:1至6:1范围内的二氧化硅(SiO 2>氧化钾(K> 2 K 2 O摩尔比的硅酸钾水溶液。 当以4.5:1至6:1的SiO 2> K 2 O摩尔比分散在水分散介质中的硅酸钾作为粘合剂的导电材料被施加以形成 CRT的漏斗上的导电层,导电层的粘附性显着增加。 使用硅酸钾作为粘合剂减少了在热抽空过程中释放的气体的量,从而缩短了排空时间。
