As photoluminescent pigment powder in the handicraft industry and the application of the toy industry, more and more customers start using photoluminescent pigment powder to alter the performance of their products, but most of the customers do not know most characteristics of photoluminescent pigment powder . Now there are many kinds of luminous powder on the market, not only the quality , but also the price has the very big difference. Mainly because the luminous powder do not have the industry standard, but it is not our traditional understanding in the consumption of the product that high price will have a relatively good performance, especially in the arts and crafts and the toy industry, the light of the time required is not so high, had higher requirements of the body color and light absorption speed . If some users don't understand some of noctilucent powder can onetime when choosing photoluminescent pigment powder, will detour in in the selection and use ofphotoluminescent pigment powder .At the end of the day is after knowing some simple properties of luminous powder, choose the luminous powder which suit oneself’s process and requirements. It is not neccessary how long can not blindly pursue bright, because all noctilucent powder in the two hours after light is very weak, and light emitting 10 hours, the test results of 20 hours is just a theory, means little in practice.
Previous articles have said the problem of the response time of the suction light, this is particularly important to the application of the toy industry in arts and crafts. The length of time are not important, instead the sign indicating industry such as light-emitting time is more important.So I hope our customers when selecting a luminous powder, should be rational to choice the luminous powder suits your company's products . Hope photoluminescent pigment powder can make people’s products application more widely.
Recently ,luminous materials domestic and abroad mainly make of ZnS, administered SrS and CaS, glow as green and yellow. SrS, CaS material easy deliquescence, brings difficultiesto the wide application . So the market mainly ZnS is administered matrix of luminescent materials. But its afterglow time only have 1 ~ 3 hours, at the same time in the bright light such as sunlight, ultraviolet light and moist air spoils easily metamorphic, so the application is restricted in many fields. Add drill, copper activation of ZnS luminescent powder administered, although there is a long afterglow time, but it has the infrared quenching phenomenon, in fluorescent lamb light(contains more red light), afterglow run out soon.
