The utility model belongs to realia technical field, is specifically related to a kind of low-light quantum environmental protection teaching magnetic film.A kind of low-light quantum environmental protection teaching magnetic film, comprises rubber magnet lamella and ecru dumb light layer of PVC; Rubber magnet lamella and ecru dumb light pvc layer are bonded together by adhesive.The visual effect of ecru that what low-light quantum environmental protection of the present utility model teaching magnetic film presented is, has namely highlighted the brightness in classroom, also there will not be reflective phenomenon, and supporting hydrolysis writing on blackboard it also avoid writes the shortcomings such as effort, wiping be not clean.
Description
Technical field
The utility model belongs to realia technical field, is specifically related to a kind of low-light quantum environmental protection teaching magnetic film.
Background technology
In educational equipment industry, school instruction generally adds chalk teaching with blackboard, green plate.After this time limit, the surface of blackboard and green plate will be worn and torn very serious, occur not writing word substantially at about 4 years in the service life of blackboard and green plate, and reflective serious phenomenon, very large harm is caused to the eyesight of student.
Nowadays, the blackboard of domestic use mainly contains cement plate, glass plate, iron sheet plate etc., and its surface is black or blackish green.It also exists the easy graying in plate face, write effort, wipe the shortcomings such as unclean, and after being erased, plate face can turn greyish white to blackboard, diminishes, be unfavorable for differentiating, increase visual fatigue, thus cause the decline of student eyesight with chalk institute book writing contrast.The intensity of reflected light of blackboard is the most weak, is unfavorable for student viewing, especially when outdoor optical is photoed badly, the light at blackboard place can be darker, the basic assurance not requirement of classroom illumination degree.Find in the coherent detection of most schools's blackboard, the ability of blackboard reverberation is low, detects qualification rate and does not generally reach 30%, and some classroom blackboard illumination qualification rate ability tens percent, can produce serious harm to the eyes of student.
Utility model content
The purpose of this utility model is the reflective phenomenon solving the existence of existing blackboard, writes effort, wipes the shortcomings such as unclean, provides a kind of low-light quantum environmental protection teaching magnetic film.
To achieve these goals, the technical solution adopted in the utility model is: a kind of low-light quantum environmental protection teaching magnetic film, comprises rubber magnet lamella and ecru dumb light layer of PVC; Rubber magnet lamella and ecru dumb light pvc layer are bonded together by adhesive.
Rubber magnet lamella is made up of ferromagnetic oxide powder, CPE and trace element, bendable, can twist with the fingers, can roll up.It can use without the need to more machining, according to required size finishing shape, and the multiple ecru PVC of rubber magnetic sheet, gum, upper UV oil.
The visual effect of ecru that what low-light quantum environmental protection of the present utility model teaching magnetic film presented is, has namely highlighted the brightness in classroom, also there will not be reflective phenomenon, and supporting hydrolysis writing on blackboard it also avoid writes the shortcomings such as effort, wiping be not clean.
Accompanying drawing explanation
Fig. 1 is the section structure schematic diagram of low-light quantum environmental protection of the present utility model teaching magnetic film.
Detailed description of the invention
As shown in Figure 1, a kind of low-light quantum environmental protection teaching magnetic film, comprises rubber magnet lamella 1 and ecru dumb light layer of PVC 2; Rubber magnet lamella 1 and ecru dumb light layer of PVC 2 are bonded together by adhesive.
Adopt low-light quantum environmental protection of the present utility model teaching magnetic film to transform existing iron sheet blackboard or green plate, magnetic pad pasting working procedure is as follows:
One, the size of blackboard or green plate has been measured with a yardstick, by required size cutting low-light quantum environmental protection teaching of the present utility model magnetic film;
Two, for 4m*1.2m plank, the blackboard that will transform or green plate rag surface wipes is clean;
Three, rag wiped clean is used in the magnetic face of magnetic pad pasting equally;
Four, magnetic pad pasting is launched, with 4 to 5 people, (number can according to size random arrangement, but two ends must arrange two people) mentioned the upper end aiming at blackboard or green plate, be adsorbed onto behind plate face until upper end and (will ensure very entirely to be adsorbed onto plate face, at the beginning of out-of-flatness, make sure to keep in mind not rigid pullling, with anti-tamper, should take off, again aim at), smooth with hand plate face of postponing, plate face can be adsorbed onto completely;
Five, by plate face rag wiped clean.In whole transformation process, can not fold.
