Preferably, described pre-treatment comprises dust-removing → bath dedusting → degreasing → pickling degreasing → first time washing → second time washing → washing → chromium-free deactivation for the third time.
Preferably, described low-temperature setting and coming out of the stove also comprises Lacquer finish and hot setting two processing technology steps between detecting.
Preferably, what adopt in described Lacquer finish is that UV surpasses weatherable powder.
Preferably, the end powder of powder electrostatic spraying of the described end is PU powder.
Preferably, the flour of described first time flour electrostatic spraying is PU powder; The flour of second time flour electrostatic spraying is that UV surpasses weatherable powder.
Preferably, the described transfer printing stove high-temperature baking that enters is the baking carried out in 180 ° of furnace temperature 25 minutes.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages: the wooden wood grain processing technology of the weather-proof Gu of 4D of the present invention, it is by once end powder electrostatic spraying and two red dog flour electrostatic sprayings, and twice low temperature semi-solid preparation and a low temperature all solidstate ensure that the outer field wood grain surfaces of aluminium section bar is without particle, coating uniform, simultaneously end powder and flour have employed PU powder and UV surpasses weatherable powder, enhance weatherability, ancient wood grain is made to can be used in more than 10 to 15 years, open air colour-fast, do not fall light, not matting, while ensureing its weatherability, there is certain landscaping effect.
Detailed description of the invention
Below the preferred embodiments of the present invention are described, should be appreciated that preferred embodiment described herein is only for instruction and explanation of the present invention, is not intended to limit the present invention.
A kind of 4D of the present invention weather-proof Gu wood grain processing technology, comprise the steps: the added punching of stock inspection → material → by model sub-material → pre-treatment → low temperature drying → end powder electrostatic spraying → low temperature semi-solid preparation → come out of the stove coating film thickness head inspection → first time flour electrostatic spraying → upper microgroove → low temperature semi-solid preparation → coating film thickness second time of coming out of the stove detect → second time flour electrostatic spraying → upper large line → low-temperature setting → detections → blanking → secondary detection → packing of coming out of the stove frame up → turn wood grain workshop → test plate (panel) → color confirmations → furnace temperature debug → open paper → bag paper → dress temperature bag → above machine → vacuumize → enter transfer printing bake oven lower machine → unpacking → paper-tear picture → melt down bright dipping → product inspection → pad pasting of coming out of the stove → cover shrink film → mistake thermal shrinkage film machine of bake → coming out of the stove by model to tighten up → paste the quality certification → finished product and put in storage; Described pre-treatment comprises dust-removing → bath dedusting → degreasing → pickling degreasing → first time washing → second time washing → washing → chromium-free deactivation for the third time; Lacquer finish and hot setting two processing technology steps are also comprised between described low-temperature setting and coming out of the stove detects; What adopt in described Lacquer finish is that UV surpasses weatherable powder; The end powder of powder electrostatic spraying of the described end is PU powder; The flour of described first time flour electrostatic spraying is PU powder; The flour of second time flour electrostatic spraying is that UV surpasses weatherable powder; The described transfer printing stove high-temperature baking that enters is the baking carried out in 180 ° of furnace temperature 25 minutes.
The object of pre-treatment is because base material and sheet material have a lot of greasy dirt and impurity before spraying, so surface of the work will through decontamination and the chemical treatment of deoiling, the greasy dirt of removing surface of the work and impurity, chromium-free deactivation wherein can produce chromaking film, improves oxygen-proof property and increases the adhesive force of coating and section bar.
Lacquer finish is that painting one or several roads varnish increase or improves the process of painting face gloss on ancient outer surface of wood layer, and the powder wherein adopted is that UV surpasses weatherable powder, can increase the brightness on surface like this; protection texture; make surperficial more beautiful bright-coloured after Lacquer finish, texture is more clear, and lines are also more smooth.
Entering transfer printing stove high-temperature baking is the baking carried out in 180 ° of furnace temperature 25 minutes, and the ink penetration of woodgrained paper can be allowed like this to the 50-60 micron of coating.
The function of melting down bright dipping mainly increases the brightness on surface, allow the ink of woodgrained paper can penetrate into coating 60-70 micron place better thus can reach 15 years colour-fast.
4D of the present invention weather-proof Gu wood grain processing technology, it is by once end powder electrostatic spraying and two red dog flour electrostatic sprayings, and twice low temperature semi-solid preparation and a low temperature all solidstate ensure that the outer field wood grain surfaces of aluminium section bar is without particle, coating uniform, simultaneously end powder and flour have employed PU powder and UV surpasses weatherable powder, enhance weatherability, make ancient wood grain can be used in outdoor more than 10 to 15 years colour-fast, do not fall light, not matting, while ensureing its weatherability, there is certain landscaping effect.
Above-described embodiment is only for illustrating technical conceive of the present invention and feature; its object is to person skilled in the art can be understood content of the present invention and be implemented; can not limit the scope of the invention with this; all equivalences done according to Spirit Essence of the present invention change or modify, and all should be encompassed in protection scope of the present invention.
