Abstract
The utility model relates to an independent dehumidifying device used in the EVA (ethylene/vinyl acetate) adhesive film production, which is mainly applied to the dehumidification in the EVA adhesive film production. The device comprises a calender roll system (1) and an EVA adhesive film (2). The device is characterized in that the calender roll region where the calender roll system (1) is located is sealed to form a closed space (3), one or more dehumidifying and drying machines (4) are arranged inside the closed space (3). The one or more dehumidifying and drying machines are arranged inside the closed part or the closed space to be cooled to complete the local dehumidification and drying treatment, increase the dehumidification and drying efficiency and improve the work environment, thereby reducing the production cost and increasing the production efficiency.
Description
(1) technical field
The utility model relates to a kind of dehydrating unit, is specifically related to the independent humidity control device in a kind of EVA glued membrane production.Be mainly used in the dehumidifying in the production of EVA glued membrane.Belong to plastic sheeting and sheet production equipment technical field.
(2) background technology
The production of plastic sheeting and sheet material needs embossing cooling etc. after die head is extruded, therefore require to reduce the temperature of roller, cools off film or sheet material with this.For strong glued membranes of cementability such as EVA, TPU, PVB,, often realize by the temperature that reduces roller for improving its production efficiency.But if ambient humidity is too high, roller surface meeting dew influences surface quality of products and performance.So will control entire environment humidity usually, waste too greatly, not only dehumidification rate is low, and weak effect has also improved production cost virtually, and humidity and health matter a lot simultaneously, how to dehumidify, and become the problem of many people's concerns.
Production with EVA solar cell package film is that example is carried out some specific descriptions below:
EVA is the copolymer of ethene and vinyl acetate, be the most frequently used material in the present solar cell package technology, mainly be made by in the EVA base-material, adding various additives such as ultraviolet absorber, UV stabilizer, antioxidant and crosslinking agent.The EVA packaging adhesive film is general adopt extrude-press polish method or extrude-hydrostomia method produces.Production process comprises melt blending, extrudes, press polish (hydrostomia), draw, batch etc.Its physical and mechanical properties mainly contains transparency, hot strength, ageing-resistant performance, shrinkage factor etc.If in press polish (hydrostomia) process, film is bonded at roll surface, oriented film then, its shrinkage factor must increase, and simultaneously, its surface quality also can be affected.Therefore technological requirement reduces roll temperature, cools off film with this, reaches the requirement of production.But the temperature reduction will inevitably be caused the another one problem, tie water exactly.Roll surface knot water will make the surface of film water wave occur, and the suction of EVA packaging adhesive film, and for guaranteeing its stable performance, it stores the environment that needs a drying, also can not have water to drop on the film in its production process.Ambient humidity generally about 70%, is reduced to about 30% with humidity and just can meets the needs of production, but will in a whole workshop appropriateness be lowered, and its production cost will increase greatly, and the workshop turnover also will be brought moisture into, influences effect on moisture extraction.
(3) summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of dehumidification rate height is provided, and effect on moisture extraction is good, the independent humidity control device during the EVA glued membrane that the dehumidifying cost is low is produced.
The utility model solves the technical scheme that its technical barrier adopts: the independent humidity control device during a kind of EVA glued membrane is produced, comprise felt wrapped roll system and EVA glued membrane, with felt wrapped roll is the felt wrapped roll zone sealing at place, form seal cavity, and one or several dehumidifying heat pumps are set in described seal cavity.
The principle of air-treatment: dry air continuously is provided.Air-treatment is the high-performance dry type dehumidifier that adopts the honeycomb fashion desiccant wheel.The honeycomb fashion runner of air-treatment continues to repeat moisture absorption regeneration action when rotated, does not influence air and flows, and the dry air of ultralow dew point continuously is provided.
The beneficial effects of the utility model are:
The utility model is airtight by part or the space that will cool off, and one of internal configurations or several dehumidifying heat pumps carry out local removal moisture drying and handle, and have improved removal moisture drying efficient, have improved working environment, thereby have saved production cost, have improved production efficiency.
(4) description of drawings
Fig. 1 is the structural representation of the independent humidity control device during the utility model EVA glued membrane is produced.
Reference numeral among the figure:
Felt wrapped roll is 1, EVA glued membrane 2, seal cavity 3, dehumidifying heat pump 4.
(5) specific embodiment
Fig. 1 is the structural representation of the independent humidity control device during the utility model EVA glued membrane is produced.As seen from Figure 1, independent humidity control device during the utility model EVA glued membrane is produced, comprise that felt wrapped roll is 1 and EVA glued membrane 2, with felt wrapped roll is the felt wrapped roll zone sealing at 1 place, closed material uses the transparency and heat-proof plate, form seal cavity 3, and one or several dehumidifying heat pumps 4 are set in described seal cavity 3.
To produce the EVA glued membrane is example, and confined space is between felt wrapped roll, and big or small about 2 square metres, ambient humidity is 70%, requires to reach between 30%～35%, in this space, uses the dehumidifier of a power 600w just to be sufficient for sb.'s need.
After producing beginning, roll surface knot water, earlier the EVA packaging adhesive film is passed each roller system, after treating that every technological parameter adjustment finishes, open increase device dehumidifier begin dehumidifying, after 3～10 minutes, roll surface steam is got rid of, the EVA packaging adhesive film is also dry, and the humidity of confined space does not cause knot water, the beginning ordinary production.
Adopt after the technique scheme, vertical shrinkage factor of the EVA packaging adhesive film of making is between 0～5%; Linear velocity improves nearly more than one times.Simultaneously, the EVA packaging adhesive film is roll banding not, and surface detail is clear, and no water wave piece is more attractive in appearance, thereby can effectively improve the package quality of solar-energy photo-voltaic cell, improves yield rate, reduces the photovoltaic generation cost.
Above-mentioned closed material is not limited only to the transparency and heat-proof plate, and enclosed material has metal material (aluminium, lead, indium, stainless steel etc.), and nonmetallic materials (rubber, plastics, pottery, graphite etc.) and composite (as rubber-asbestos board) are also arranged.
Claims (1)
1. the independent humidity control device during an EVA glued membrane is produced, it is characterized in that described dehydrating unit comprises felt wrapped roll system (1) and EVA glued membrane (2), it is characterized in that: with the felt wrapped roll zone sealing at felt wrapped roll system (1) place, form seal cavity (3), and one or several dehumidifying heat pumps (4) are set in described seal cavity (3).
