Abstract

The equipment for preparing columned amalgam includes following parts: punching oil cylinder; up going oil cylinder and stand; up molding board installed on the punching oil cylinder; low molding board installed on the up going oil cylinder; punching needle being fixed on the up molding board; nose spike fixed on the low molding board; die hole set up on the bottom die. Top part of the nose spike is inside the die hole of the bottom die. Using press equipment and molding press method to produce columned amalgam, the invention guarantees consistent diameter and regular shape of amalgam so as to meet both requirements of technique and performance of fluorescent lamp.

Description

technical field [0001] The invention relates to an alloy material for fluorescent lamps, in particular to a device and method for preparing cylindrical amalgam for fluorescent lamps. Background technique [0002] The function of amalgam for fluorescent lamps in the lamp tube is to release mercury in the alloy at a certain temperature to form mercury vapor, and the electrons emitted by the cathode of the fluorescent lamp collide with mercury atoms, making the outer electrons of mercury atoms transition from the ground state to At a high energy level, because the electrons at the high energy level are unstable, when these electrons return to the ground state, they can release a wave with a wavelength of 183.4nm, and the fluorescent powder coated on the glass tube of the fluorescent lamp is activated by this wave to emit light. Mercury can be alloyed with many metals and made into different shapes, but strictly controlling the content of mercury in each amalgam and the shape of...
