Luminous glow in the dark pebbles spraying operations Safety Measures

A spraying operations personnel must undergo safety training, are not allowed to work without training.photoluminescent pigment suppliers Must conduct a comprehensive inspection of all equipment and tools before painting 2 paint job, confirmed before work, no problem.3 paint workplace ventilation cleaning should conform GB 6415 requirements.tions, enterprise security technology sector should set up special timed in the air in a confined space measuring oxygen content and concentration of combustible gas, oxygen content should be more than 18%, combustible gas concentration should be less than 10 percent of the lower explosive limit.5 paint job cabin equipped with at least two or more co-operation, if the workplace is too small, can only accommodate one-man operation, the other person should be responsible for monitoring.6 high paint job should follow the "ship construction high operating safety regulations."Support simultaneous operation over seven guns must be opened spacing (about 5m), according to a certain, in the same direction for spraying.8 special coating operations, its spray equipment and hoses should be set up by professionals, if the equipment fails or there are unusual circumstances, the withdrawal of
extravehicular first notify the cabin staff by service personnel.
9 airless spray high-pressure jets and leaks can cause serious injury, the job should be done:. a gun nozzles are not allowed at any time against others and their own;.Photoluminescent Tumbled Gravel b must not touch the nozzle with a finger, or peep muzzle; c when cleaning the gun, to drive off the pump source, let go of stress, and safety devices are sold guns to be cleaned;d. When the gun is stopped, you must live in the safety latch.10 After work is completed, the gun must promptly withdraw extravehicular, ventilation and continue until the film is completely cured.After 11 paint job, the workplace should be clean, paint and solvents remaining promptly returned to the warehouse, are not allowed to misplacing.12 The operator must wear protective masks, rubber gloves, protective goggles, and other related products.Problems and Solutions

Note of phosphor

ure and high friction (luminous powder will change the existing structure). With radioactive luminous, is the incorporation of radioactive substances in the phosphor, the use of radiation emitted by radioactive substances continue to excite phosphors, these luminous luminous very long time, but little environmental pollution and toxic and hazardous applications. Edit this section apply in life applications people use in real life long luminous light-emitting properties, made weak lighting, the military has a special use, this material is applied to the aviation instruments, watches and clocks, windows, various switches on the machine sign, door handles, etc., can also be used together with a variety of translucent plastic pressed into a variety of symbols, parts, supplies (such as power switches, sockets, fishing hooks, etc.). These light-emitting components after light irradiation, or unexpected power outages at night, getting up after lightning and so it continues to emit light, so that people around discernible direction, bring convenience to work and life. The ultra-fine particles of luminous materials incorporated in textiles, to make the color more vivid,
luminous textile kids wear, can reduce traffic accidents.
powdered paint pigments Application in industry as luminous in the handicraft industry and the toy industry applications, more and more customers began to change the use of luminous performance of their products, but many of the features luminous powder itself is not the majority of customers know, for example, there are now a variety of luminous powder on the market, there is a difference not only the quality, the price is also very different, a lot of customers is difficult to buy their favorite luminous. Mainly because there is no industry standard luminous yet, but it is not our traditional understanding of the consumer in the high price of the product, there must be a relatively good performance, especially crafts and toy industry, less demanding on the luminescence time for the body color and absorbance speed requirements to be higher, if some users choose luminous, without knowing the luminous performance of some time, it will take some detours in the selection and use of luminous in the final analysis, we must first understand after some simple properties of luminous choose luminous process and requirements for their best, do not blindly pursue energy light how long, all luminous in two hours after the light is very weak, said LED 10 hours, 20 hours is only the detection result by theory, in practice the effect is not obvious. Previous articles have said the problem absorbance response time, which is the point of application of crafts and toy industry is particularly important, but the duration of luminescence has not very important, signs and other luminous time indicates the industry was important, so I hope customers Select luminous time, to the rational choice for their company's products luminous, luminous willing to give you a broader application of the product

Photoluminescent Tumbled Gravel production process

I. Features: This is different from the luminous phosphors, which non-radioactive, light long short but luminous efficiency, low cost, colorful.
Second, the device: furnace, crucible, ball mill, drying equipment.
Third, the formula:
Red luminous powder: barium sulfate 55 g, 40 g of magnesium sulfate, lithium phosphate, 2 g of copper nitrate 3 g
Blue luminous: 63 g calcium sulfide, sodium 5 g, 5 g of potassium sulfate, strontium sulfate 10 g, 6 g of sodium chloride, 1 g of silver nitrate, magnesium sulfate 10 g.
Purple luminous: 63 g calcium sulfide, magnesium sulfide 26 grams, 10 grams of sodium sulfide, strontium nitrate 1 g.
Green luminous: 55 g calcium sulfide, potassium sulfide 1 g, 10 g of sodium sulfide, barium nitrate, 12 grams, 13 grams of indium nitrate.

Glow in the dark materials

Glow in the dark materialsThe law mainly Al2O3, SrCO3, Eu2O3, Dy2O3 as raw material , adding a certain amount of flux ( such as boric acid ) , Photoluminescent Tumbled    Gravel, generally the first high temperature (1350 ℃ or so ) calcined , and then restored at a slightly lower temperature that Eu3 + becomes Eu2 +, reducing atmosphere can be 2% H2 +98% N2 to create , we can use a confined space to place active carbon . Finally, after cooling , fine grinding and sieving to obtain the product . This method is very obvious advantages of simple process , microcrystalline crystals of good quality, suitable for industrial production .Phosphorescent sand

phosphorescent pigment

phosphorescent pigment paint , oil, black, plastic , decorative gravels glass , ceramics, chemical materials , to achieve self-luminous function media should exhibit good low lighting instructions and decorative landscaping effect.
Luminous crystal structure of a stable luminescent materials , luminescent properties under the premise of the crystal structure can ornamental masterbatch permanently absorption - Storage - light, performance in general service life of up to 20 years.
Luminescent pigment in the range of -20 ℃ -1080 ℃. Luminescent properties of fundamental change.Glow in the dark pebbles
