Processing and manufacturing.The two-sided hydrophilic film produced can greatly improve the blood diffusion of blood sugar test paper hydrophilic film, in favor of into
The detection accuracy of one step raising blood glucose target.
To achieve the above object, the present invention adopts the following technical scheme:
A kind of manufacturing method of two-sided hydrophilic film, the two-sided hydrophilic film, including substrate are coated with upper layer in the upper surface of substrate
Hydrophilic film is coated with lower layer's hydrophilic film in the lower surface of substrate, upper layer PE film is compounded in the upper layer hydrophilic film, described
Lower layer's PE film is compounded in lower layer's hydrophilic film, the manufacturing method of the two-sided hydrophilic film includes the following steps:
Step 1: first it is coated with lower layer's hydrophilic film
Substrate is released from substrate coiled strip emptying roller, becomes horizontal transmission through guide roller guiding and its following table is face-up, lower layer
Hydrophilic film coating die head is above coated the lower surface of substrate；
Step 2: compound lower layer PE film after drying
The substrate for being coated with lower layer's hydrophilic film enters dry baking tunnel and is dried, after lower layer's hydrophilic film is dried, lower layer's PE film from
It is released on lower layer's hydrophilic film coiled strip emptying roller, it is compound to the substrate taken turns be coated with lower layer's hydrophilic film by the first compound rolling；
Step 3: it is coated upper layer hydrophilic film
It is coated with lower layer's hydrophilic film and the substrate for being compounded with lower layer's hydrophilic film is oriented to wheel through the first compound rolling, become horizontal biography
Give and its upper surface upward, upper layer hydrophilic film coating die head is above coated the upper surface of substrate；
Step 4: compound upper layer PE film after low temperature drying
The substrate for being coated with upper layer hydrophilic film enters low temperature drying channel and carries out low temperature drying, after upper layer hydrophilic film is dried, on
Layer PE film is released from the PE film roll material emptying roller of upper layer, by the second compound rolling to wheel and the substrate for being coated with upper layer hydrophilic film
It is compound；
Step 5: it cuts
The two-sided hydrophilic film of finished product is sent to cutter to wheel by the second compound rolling and cuts.
Compared with prior art the beneficial effects of the present invention are: the manufacturing method of the two-sided hydrophilic film of the present invention, it is ensured that on
Lower hydrophilic film, towards above, and avoids coating and is destroyed not with other component contacts before it is dried in coating.It is existing
Blood sugar test paper, be to be coated with hydrophilic substance in a surface (i.e. single side) of substrate, it is dry to pass through coating drying tunnel, hydrophilic substance
It adheres to substrate surface and constitutes hydrophilic film, then the compound PE film in hydrophilic film.Two-sided hydrophilic film of the invention, works as substrate
After coating and compound PE film are completed in upper surface, when in substrate lower surface, coating hydrophilic film enters drying tunnel drying, because of the dry temperature of drying tunnel
Degree is higher, can deform, blister, delamination after the PE film of upper surface is heated, in order to solve this problem, hydrophilic coating of the invention is molten
The agent spirit solvent easily dry using low temperature avoids the destruction to PE film this makes it possible to using cold drying drying.
