Device product is treated, U.S. FDA need to be sampled inspection when import is entered the GATT to disposable medical gloves.China is disposable glove
Big producer's (especially disposable PVC glove).Currently, polymer/disposable glove sealing propertytest is generally used
Method are as follows: air will be filled with inside gloves, gloves is crimped towards finger orientation, and keep disposable glove be open envelope
It closes；When curling to a certain extent after, air inside gloves pressure due to compression increases, and promotes disposable glove to expand, then
The phenomenon that leaks air is detected whether by artificial observation.
This detection mode is widely used in polymer/disposable glove production field, and this mode to detect people
The heavy workload of member, needs to install, inflate, detects and win gloves, and entire process requires testing staff to complete, spends
Time is long and inefficiency, and accuracy is also low.Existing on market today about the device of medical gloves is all its health peace
It is also the with the naked eye rough inspection of staff for whether medical gloves has slit from the aspect of the selection of complete and material, this
Hidden danger just is brought to the disease for needing to perform an operation life security, thoroughly removing for this underproof medical gloves is to need at present
It solves the problems, such as.
Summary of the invention
In order to overcome the drawbacks of the prior art, the present invention provides a kind of device of polymer gloves detection, can be simply fast
Speed detects the gloves of larger loophole, and is able to detect the gloves of smaller loophole, and detection efficiency is high, and can be realized and seal to gloves
The detection of property.Polymer gloves in the present invention include natural emulsion gloves, butyronitrile gloves and PVC glove etc..
In order to solve the above technical problems, the technical scheme adopted by the invention is that:

(Na2SO4)=(15.4+1.20) g/L.
Preferably, the precision of the voltmeter is ± 3mV.
Compared with prior art, the present invention has the following technical effect that
1, a kind of gloves support frame for simulating true man's palm is devised, gloves can be made to the maximum extent tight in all directions
It is taut, it expands slit existing for script and electrolyte is allowed to pass through, be difficult to so as to avoid electrolyte under relaxed state through slit
Cause to be difficult to detect by the problem come；
2, it is capable of the gloves of the simple and quick larger loophole of detection, is able to detect the gloves of smaller loophole；It can not only realize
Detection to gloves leakproofness, and detection efficiency is high.
3, apparatus structure is simple, cheap, helps to control production cost.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of polymer gloves slit detection device of the invention；
In the accompanying drawings, list of designations represented by each label is as follows:
1 --- metal die；2 --- detected gloves；3 --- first electrode；
4 --- electrolytic bath；5 --- second electrode；6 --- resistance；
7 --- regulated power supply；8 --- voltmeter.
Specific embodiment
The principle and features of the present invention will be described below with reference to the accompanying drawings, and the given examples are served only to explain the present invention, and
It is non-to be used to limit the scope of the invention.
It please refers to shown in Fig. 1, is the structural schematic diagram of polymer gloves slit detection device of the invention.The polymerization
Object gloves slit detection device includes: metal die 1, first electrode 3, electrolytic bath 4, second electrode 5, resistance 6, regulated power supply
7 and voltmeter 8, wherein
The metal die 1 is the gloves support frame of simulation true man's palm, has palmar hand and the five fingers portion, detected
Gloves 2 are set in outside the metal die 1；
