Abstract
The utility model relates to a tester for a dripless character and an antifogging properties of a plastic film. The tester is composed of a shed frame, a constant temperature water bath box, a water drop collecting device, a temperature controlling device, etc. The utility model is characterized in that the shed frame at the upper part uses a metal frame provided with glass; the constant temperature water bath box is controlled by using an electronic temperature controlling device. The utility model has the advantages that the structure is compact, the operation is convenient, the visual property is strong, the simulating property and the reproducibility are good, the tester can test the dripless character and the antifogging properties of the film at the water bath temperature of 35 DEG to 75DEG, and the utility model can quantitatively test the dripless character and the antifogging properties of the film under the condition that the water bath temperature is 10DEG to 20DEG and the environment temperature is 30DEG to 0DEG.
Description
A kind of plastic sheeting anti-fogging property and antifog property testing instrument are applicable to accelerated test plastic sheeting anti-fogging property, antifog property, and do not have the persistence of droplet.
In recent years, because to the polyfunctional requirements such as antifog, longevity of agricultural canopy film, several big-and-middle-sized plastic sheeting for farm use manufacturing planies and part R﹠D institution began to attempt detecting in the laboratory anti-fogging property of plastic sheeting for farm use.Some unit adopts beaker, the water of packing into, and rim of a cup covers plastic film sample, puts into water bath with thermostatic control, observes film and the water droplet situation occurs.The unit that also has adopts syringe to press close to the plastic sheeting of being fixed by adhesive tape according to wetting theory, releases close big droplet number droplet, final wetting areas (mm behind the record certain hour
2).Some units adopts water bath with thermostatic control button shed device, testing film at a certain temperature, 50% loses the time of anti-droplet effect, but can't the antifog property of quantitative response.
The utility model purpose provides the tester of a kind of accelerated test plastic sheeting anti-fogging property and antifog property, drips antifog property with nothing quick, the quantitative evaluation film.
This tester is divided into following several sections, and top is the frame of being made up of an inclined-plane and a plane test face, and constant water bath box is equipped with in the bottom, and water bath one end (low side on frame inclined-plane) has an inclined-plane water droplet gathering-device, and the other end is equipped with temperature controller.Frame adopts metal, and for example aluminium alloy, stainless steel etc., and the band bezel is housed have corrosion-resistant, good, the easy observation of the transparency, puts film, to get film convenient and swift.The control system of constant water bath box adopts the electronic temperature control device, and safety, accurate can be used for a long time.The water droplet gathering-device comprises a skewed slot and a collecting bowl, is contained in water bath one end, and rim of a cup and the water leg outlet of catchmenting is joined, and is compact to design, easy to use.
The utility model device can effectively be simulated practical booth environment, and experimental period is short, intuitively accurate, easy to operate, economical and practical etc.
Accompanying drawing 1 is the utility model device synoptic diagram.In the accompanying drawing 1: 1-frame 2-side glass 3-temperature controller 4-water bath 5-collecting bowl 6-water leg
Embodiment 1: the utility model manufactures and designs with reference to accompanying drawing 1, during testing film, plastic sheeting to be measured has been cut out standby, and its length and width should be than the big 10cm of frame upper surface.Add clear water in constant water bath box, the water yield should keep container 2/3 height.Connect the temperature controller power supply, the temperature indication is transferred to 45 ℃.When traffic lights were alternately beated, expression entered temperature constant state.At this moment, detain canopy immediately, computing time.In the plane, water droplet begins earlier to drip on which kind of film, this film initial stage do not have drip effective.Treat that film inclined-plane and plane do not have the globule fully, when all forming moisture film, for the initial stage does not have the time of dripping.As a kind of nothing of testing certain factory is dripped the film initial stage, and not have the time of dripping be 45 minutes.Make device keep constant temperature, uninterruptedly carry out 24 hours every days.Should often observe water level during this period, make it to remain on 2/3 height.When the area of the white globule reached 50% in flakes on the film, being judged to be to lose did not fully have the effect of dripping.The used time is not for effectively there being the time (in fate) of dripping.For example a kind of nothing of certain factory is dripped film, and it does not effectively have the time of dripping is 50 days.
Embodiment 2: this example needs the refrigerator-freezer that can keep flat anti-fogging property and antifog property testing instrument, and 5 ℃～-30 ℃ of its freezing scopes are preferably 0 ℃～-20 ℃.With the refrigerator-freezer temperature stabilization at-10 ℃.The utility model tester is steadily put into refrigerator-freezer, add clear water in water bath with thermostatic control, the water yield remains container 2/3 height.Energized, it is 20 ℃ that the temperature indication is transferred to.Detain canopy this moment immediately.When traffic lights were alternately beated, expression entered temperature constant state, computing time.Make device keep constant temperature, uninterruptedly carry out 24 hours every days.If necessary, from the water droplet collecting bowl, draw water, metering, record.Fog and water droplet situation in the viewing film.The water droplet amount of collecting with continuous 120 hours (5 days), as initial antifog property quality criterion.The water yield is many more, and the film initial stage, antifog property was good more.When all being that the uniform small globule and film have mist, when smudgy, promptly judge it is that antifog property completely loses on the film; The used time is effective antifog time of this film.For example, certain does not have the common PE film of antifog property, and the water yield of collecting in 120 hours is 269ml; Test a kind of antifog drop films of certain factory, the water yield of collecting in 120 hours is 485ml.The antifog property of initial stage that can judge this antifog drop films of factory thus is good.
Claims (4)
