Description
Technical Field
The utility model belongs to the technical field of chemical experiment equipment or device, concretely relates to gas permeability detection device of waterborne polymer film.
Background
The water-based paint, also called water-based paint, is a water-containing paint which takes water-soluble or water-dispersible polymer resin as a main component, and compared with oil-soluble paint, the water-based paint is more energy-saving and environment-friendly, thereby having larger market space. The polymer film material prepared by using the water-based paint as a base material is widely applied to the aspects of preservation of vegetables, fruits, foods and the like, heat preservation of crops, packaging and storage of medicines and the like. The air permeability of the water-based polymer film material is one of the most important physical properties of the water-based paint, and the possible application fields of the water-based polymer film material are directly determined by the air permeability, so that the water-based polymer film material has important practical value for measuring the air permeability of the polymer film. At present, the air permeability of the polymer film is usually completed by adopting an air permeability tester, and the test result is usually expressed by the amount of air permeating per unit area of the polymer film under a certain pressure and within a certain time, but the tester is expensive, a professional testing organization can buy and use the tester, and the problems of long test period, high test cost and the like exist.
Disclosure of Invention
The utility model aims to solve the technical problem that overcome above-mentioned prior art's shortcoming, provide a gas permeability detection device of water-based polymer film of simple structure, with low costs, test cycle weak point.
The technical scheme for solving the technical problems is as follows: the outer barrel with scale marks on the outer surface is arranged on a support of the iron support, the bottom of the outer barrel is provided with a water-based polymer film in a sealing manner, a push rod is arranged in the outer barrel to push a rubber plug which moves up and down, and the upper part of the push rod is provided with a weight placed on a weight base.
The utility model discloses a weight of different weight is placed on the weight base, implements constant pressure to the push rod, and the push rod promotes the plug and down moves, exerts constant pressure according to the weight, and the quantitative is gaseous through the used time of waterborne polymer film in the test urceolus, and then calculates the gas permeability of waterborne polymer film, the utility model has the advantages of testing arrangement is with low costs, test period is short, the utility model discloses satisfy the needs of the preliminary test of all kinds of polymer film gas permeability of laboratory or enterprise.

It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
As shown in fig. 1, the air permeability detection device of the aqueous polymer film of the present embodiment is composed of a weight 1, a weight base 2, a push rod 3, an outer cylinder 4, a rubber plug 5, a scale mark 6, an aqueous polymer film 7, and an iron support 8 connected in series.
Install urceolus 4 with the fixation clamp on the support of iron stand platform 8, be marked with scale mark 6 on the surface of urceolus 4, sealed membrane winding water-based polymer film 7 is used to urceolus 4 bottom, install push rod 3 in the urceolus 4, plug 5 is installed to 3 bottoms of push rod in the urceolus 4, plug 5's diameter equals with the internal diameter of urceolus 4, push rod 3 can promote plug 5 in the urceolus 4 and be up-and-down motion, weight base 2 is installed on 3 upper portions of push rod, place weight 1 on the weight base 2.
The operation steps of this embodiment are as follows:
(1) manually pulling the push rod 3 and the rubber plug 5, and extracting quantitative air according to the scale marks 6 on the outer cylinder 4;
(2) selecting three weights 1 of 50g, 100g and 200g and placing the weights on a weight base 2, applying constant pressure to a push rod 3, pushing a rubber plug 5 by the push rod 3 to move downwards, applying constant pressure P according to the weights 1, testing the time t for a fixed amount of gas V in an outer cylinder 4 to pass through a water-based polymer film 7, and further calculating the air permeability of the water-based polymer film 7 according to the following formula
Wherein K is air permeability and the unit is cm3/KPa·m2·s；
V is the amount of gas permeated in cm3；
P is the applied pressure in kPa;
s is the air permeable area in m2；
t is the time taken for the gas to pass through, and is given in units of s.
(3) And calculating the average value of the air permeability of the water-based polymer film 7 according to the three film air permeability test experiments, thereby obtaining the air permeability of the water-based polymer film.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention.
