The role of cold light pipes in the disaster area guides in coal mines

In the firefighting and coal mine ambulance teams, the stricken area guides are commonly used. The commonly used stricken area guides are divided into the cold light type and the battery, among which the cold light type is necessary on the coal mine. The stricken area guides are suitable for the mine ambulance team to handle the afflicted area and use it as road signs for unfamiliar mine roadways and complex environments. The effective use time is about 24 hours.
The cold light type fluorescent stick consists of two parts: a plastic tube and a glass tube filled with different liquids. When used, the fluorescent finger is gently bent, the glass tube in the plastic tube is broken, and the two liquids are thoroughly mixed by gently shaking. In order to achieve a good glow. Fluorescent light guides are widely used luminous articles, can be used as a guide for mine lifesaving, sea lifesaving, night sign signals, etc. Fluorescent typed light guides (light sticks) are used in transportation and preservation of fluorescent type guides in transportation and During the preservation process, high temperature exposure and gravity impact or drop should be avoided. In order not to affect the lighting time and brightness of the fluorescent device, and to avoid breaking the glass tube in the fluorescent device, the fluorescent device emits light in advance so that the fluorescent device fails.
Fluorescent light guides (light sticks) Precautions The liquid in the fluorescent guides is not edible. Never use a knife or scissors to break the fluorescent guide's plastic tube. Do not twist the fluorescent guides to prevent fluorescence. Leak in liquid in the diverter.
Fluorescent light guides (light sticks) Light-emitting principle Fluorescent light guides are mainly composed of three substances: peroxides, esters and fluorescent dyes. Simply put, the principle of the fluorescence-type light emitting device is that the peroxide reacts with the ester compound to transfer the reacted energy to the fluorescent dye and then the fluorescent light is emitted from the dye. In fluorescent devices, a sandwich is usually placed. The peroxide and the ester compound are isolated inside and outside the sandwich. After rubbing, the two compounds react to make the fluorescent dye glow.
The main technical indicators of the energy disaster locator are: continuous use time<24h
Supply voltage 3V (two AA batteries)
Working current <70mA
Short circuit current <5A
Effective use distance >100m

Stainless Steel Pillow Bearing

Stainless Steel Pillow Blocks mounted units are made of corrosion resistant stainless steel and are ideal for the food handling industry, water treatment plants, and salt water desalinization plants. Balls & Rings are made out of 440 Stainless Steel, Set Screws 410 Stainless Steel, slinger & Seal Frame 302 Stainless Steel, Retainer 302 Stainless Steel, Set Screw locking Collar (SNA only) 304 Stainless Steel, Seal Silicone Rubber Lubrication H-1 Food Grade Grease Operating Temp.
