luminescent sheets when heated process

Luminous plastic luminescent material when heated process , they often turn black , affecting play its luminescent properties .realglow luminous masterbatch by equipment selection and process conditions to control both . Choose one with improved processing equipment. By adjusting the screw configuration , so that the processing of reducing the shear and friction material , to reduce the degree of blackening of the material. (I) reduce the aspect ratio of the screw to screw the best selection of aspect ratio 20 / 1 , can reduce powdered paint pigments time in the barrel , reducing the likelihood of products blackened . (Ii) Reduction of the form of adjustment screw engaging a screw block module , remove the five pairs of engagement blocks , the block into the thread and re- combining element arranged to reduce friction on the luminescent material .
