Flame processor works and application: Processor is used in most of the flame PP, PET, PE plastic. We often give a number of electronic hardware manufacturers to produce some special flame processor, such as Guangzhou Toyota IBC flame plane processor, a famous brand of sound The processor also bumper horn flame flame treatment. PP, PE plastic is non-polar polymer materials, chemical stability, low surface tension, when added together with the opening of synthetic resin agents, antistatic agents, anti-aging agent of influence is difficult to bond with the solid ink. To improve the PP, PE plastic, printability, must deal with to the surface tension of not less than 3.8 × 10-2N / m.

(1) The flame treatment

Flame treatment for surface treatment of small plastic containers, the principle is to heat the plastic surface decontamination and melting the surface coating to improve the surface adhesion of the ink.

Specific operation is: will the container to be processed into gas flame, the flame length control in the inner core 6 ~ 19mm, the flame away from the core to the top surface of the container 6 ~ 25mm, contact time 0.1 ~ 1.0s, rotation speed of 100 to 150 r / min.

Flame in the excited state contains and-NH-OH and other free radicals, with the combination of polymer plastic surface hydrogen, and the introduction of a number of polar functional groups, the occurrence of chain scission reaction, the wettability of the plastic surface , Adhesion can be improved.

Detection of treatment effect

The easiest way is to use the surface tension of the test document for testing. Use 3.8 × 10-2N / m surface tension of the test specification document, if the test solution marks the places where strokes evenly spread, not contraction, then the treatment is better; if liquid contraction marks, or marks part of the contraction solution, not part of contraction, then the treatment is not sufficient.
