To solve the above problems, quasi- use such a PET transfer membranes utilization process, in turn include the following steps：
Basement membrane coating is aluminized and is shifted, and scraper type coating, dry glue amount are carried out by carved intaglio gluing or gravure anilox roll
Control is in 4~6g/m2, coating weight is uniform, after the backsizing of basement membrane, first passes through baking oven drying, and basement membrane is run with paper synchronous,
Basement membrane goes out after baking oven using deep fat roller transient heating, and keeps basement membrane compound with paper by the effect of pressure roll in time, cooling
After remove, shift gel coating peel strength control between 0.5-1.2 N/in, can by adjusting apply glue formula realize stripping
The control of intensity；
Basement membrane recycles and rewinding processing, and rewinding processing includes basement membrane dedusting, destatics, rewinding and connector splicing
And arrangement；
Reuse film is coated with, and to treated, recycling basement membrane is coated, and by carved intaglio gluing, dry glue amount is controlled 4
~6g/m2；
Reuse aluminium coated film and reuse film transfer；
Basement membrane is recycled again after reuse film transfer, and repeat above-mentioned rewinding processing and subsequent step and so on to make base
Film recycles 3-5 times.
The described technique carries out printing using Sai Ludi gravures equipment and line transfer is compound.Make full use of company Sai Ludi
Gravure equipment has both the advantage of printing and line transfer complex function.
Deep fat roll temperature is controlled at 120 DEG C.
Using dry type transfer, complex method.
Compared with prior art, the present invention major advantage is as follows：
1. the present invention breaks through the control of transfer gel coating and the old basement membrane dedustings of PET, destatics the key technologies such as processing, realize
It can be used for the vacuum aluminum-coated transfer PET basement membrane reuse technologies of actual production, PET basement membranes reuse 3-5 times, technology reaches domestically leading
Level, it is resource-effective in realization production process by improving raw material reclamation rate, white pollution is reduced, has been pushed to green
Printing, the transition of environmental printing.
2, present invention process is in " your cigarette（Hard sealwort product）Capsule ", " white sand（Fine work）It is obtained on the products such as capsule "
It is practical to promote and apply.It is consumed by basement membrane reuse with glue is reduced, makes the average unit cost of existing production main raw material(s) aluminized paper
11000 yuan/ton are reduced on the basis of from 17000 yuan/ton of outsourcing, decreases by 30% or more, drop more per ton than outsourcing PET basement membranes
Low 2060 yuan/ton, great application value.
Specific implementation mode
To make the object, technical solutions and advantages of the present invention clearer, present invention work is further retouched in detail below
It states,
Embodiment：
The present embodiment provides a kind of PET transfer membranes utilization process, in turn include the following steps：
Basement membrane coating is aluminized and is shifted, and transfer adhesive coating characteristic has this project basement membrane reuse effect vital
It influences, is mainly reflected in coating stripping intensity and is with the control of thickness, the influence of wherein peel strength is applied：Intensity is excessive,
It is removed not exclusively when transfer, film surface of aluminizing has remnants, influences printing effect and again reuse effect；Intensity is too small, coating performance
Difference influences aluminium coated affinity, causes compound rear aluminium plating membrane easily to migrate, is unevenly coated, the residual solvent in glue
Ink layer can be infiltrated, product is made spot phenomenon occur.
For this purpose, using dry type transfer, complex method, scraper type painting is carried out by carved intaglio gluing or gravure anilox roll
Cloth, dry glue amount are controlled in 4~6g/m2, coating weight is uniform, after the backsizing of basement membrane, first passes through baking oven drying, basement membrane and paper
Synchronous operation, after basement membrane goes out baking oven（Film is not completely dried when going out baking oven）Using 120 DEG C of deep fat roller transient heatings, and in time
By the effect of pressure roll, keep basement membrane compound with paper, removed after cooling, the peel strength for shifting gel coating is controlled in 0.5-
Between 1.2 N/in, the control of peel strength can be realized by adjusting painting glue formula；
Basement membrane recycles and rewinding processing, and rewinding processing includes basement membrane dedusting, destatics, rewinding and connector splicing
And arrangement；
PET basement membranes are in composite transferring since the thickness deviation of transfer paper, equipment roller platen pressure at two ends are less than centre
With the transfer factors such as roller platen Concentricity tolerance, it is imperfect to there is a degree of stripping always.And basement membrane is rolled up in rewinding
It can rub and generate a large amount of electrostatic charges, adsorb the dust and aluminium powder floated in air.When being shifted with untreated recycled PET basement membrane
Aluminium layer fastness is poor, and transfer face spottiness has incompleteness, and crack phenomenon fine crushing is will appear when serious.In order to ensure final product quality and printing
Adaptability, it is necessary to the PET basement membranes of reuse is dusted and destatic processing.General papermaking enterprise comes by special dust-free workshop
Purification, production and storage vacuum aluminium-plated paper, and printing enterprise does not have such condition generally.For the PET bases that avoid that treated
Film regenerates dust and electrostatic, needs to be combined with equipment and technology by technique, synchronously completes device development and transfer coated
The technological transformation of equipment realizes that printed on line, stripping, dedusting destatic processing, rewinding, connector, puts into the continuous of printing again
Formula production procedure.
Basement membrane dedusting destatics the patent applied in the early time using the applicant：One kind removing electrostatic dust absorption device（ZL 2013
2 0579169.8）.PET reuses film has the stainless steel of a large amount of high conductivity diameter 12u fine by two electrostatic banister brush in brush
Dimension, fiber finer tip have concentrated electrostatic field charge and have ionized surrounding air, brush point contact film surface, make opposite polarity ion towards electrostatic
Lotus fast moves, and neutralizes it, eliminates electrostatic to the front and back of film so that suction of the film to fine impurities that treated
Attached reduced capability.
The dust impurity that outside is adhered in film is removed from film surface by the combined pressure of two Roller for sticking dust again.Two binding dusts
The both sides of roller respectively fill a cleaning roller for posting double faced adhesive tape, and cleaning roller is clean by the removing of binding dust roller surface again.Adhesive tape is general
It replaces when shutting down or is replaced regarding effect of sticking dust not timing.The diameter setting of cleaning roller is twice of Roller for sticking dust, therefore adhesive tape pastes
The number for replacing adhesive tape can be reduced by closing area bigger, improve efficiency.
The winding of film requires end face neat, and side requires ± 1 millimeter of deviation, and winding tension is uniform, not tension pine corrugation excessively.
Monovolume film connector uses two-sided overlapping technology, makes the connector no more than 3 of a wound membrane, does not influence to produce and use again.Repeat profit
The aluminium coated that transfer membrane both sides are not shifted down completely should ensure that within 3 millimeters, be used in order to avoid influencing next time.
Reuse film is coated with, and to treated, recycling basement membrane is coated, and by carved intaglio gluing, dry glue amount is controlled 4
~6g/m2；
Reuse aluminium coated film and reuse film transfer again recycle basement membrane after reuse film transfer, and repeat above-mentioned rewinding processing
And subsequent step and so on makes basement membrane recycle 3-5 times.
