Abstract
The utility model discloses a kind of anti-static shielding bag, its drip irrigation device comprises bag, and described bag is sealed successively by antistatic polyester layer, antistatic polyvinyl chloride layer, Antistatic Nylon layer and anti-static polythene layer from outside to inside and forms.The better effects if of the utility model antistatic.
Description
Technical field
The utility model relates to a kind of antistatic packaging field, and more particularly, it relates to a kind of anti-static shielding bag.
Background technology
But electrostatic is a kind of physical phenomenon of common complexity, to be present in life everywhere.Along with the fast development of science and technology, the extensive use that electronic devices and components obtain, also makes the environment of electrostatic more and more worsen simultaneously, and components and parts such as metal-oxide-semiconductor, crystal oscillator, single-chip microcomputer, the integrated circuit etc. responsive to electricity cause serious threat.
Traditional anti-static shielding bag is only be composited by two-layer antistatic material, and the effect of antistatic is also bad, and cannot ensure that electronic devices and components in shielding bag and electrostatic field are thoroughly isolated, namely electronic devices and components still may be affected by electrostatic field.In addition, shielding bag is opaque mostly, cannot observe from the outside, recognize electronic devices and components, usually needs to take shielding bag apart to observe, recognize inner electronic devices and components, and this just seems very inconvenient.
Utility model content
For the deficiency that prior art exists, main purpose of the present utility model is to provide a kind of anti-static effect better shielding bag.
For realizing above-mentioned main purpose, the utility model adopts following technical scheme: a kind of anti-static shielding bag, comprise bag, described bag is formed by antistatic polyester layer, antistatic polyvinyl chloride layer, Antistatic Nylon layer and anti-static polythene layer successively hot melt from outside to inside.
As preferably, described antistatic polyester layer is PC layer, and described PC layer thickness is 10 μm.
As preferably, described antistatic polyvinyl chloride layer is layer of PVC, and described layer of PVC thickness is 8 μm.
As preferably, described Antistatic Nylon layer is transparent PA layer, and described PA layer thickness is 8 μm.
As preferably, described anti-static polythene layer is PE layer, and described PE layer thickness is 10 μm.
As preferably, described antistatic polyester layer is also coated with antistatic oxidant layer.
As preferably, described bag also has Self-enclosing structure.
The utility model hinge structure is compared to be had: can form inductive effect and isolate with electronic devices and components in protective bag and electrostatic field, the inside one deck is by the polyethylene layer can eliminating electrostatic, effectively prevent from producing electrostatic in bag, better the electric sensitive components of protection endangers from potential electrometer; And the sack after heat-sealing is translucent, just can know recognition interior items from the outside, not need dismounting even to destroy sack to observe, recognizes.

In figure: 1, PC layer; 2, layer of PVC; 3, PA layer; 4, PE layer; 5, antistatic oxidant layer; 6, bag; 7, Self-enclosing structure.
Detailed description of the invention
Referring to figs. 1 through Fig. 2, the utility model anti-static shielding bag embodiment is described further.
A kind of anti-static shielding bag, comprise bag 6, bag 6 is formed by antistatic polyester layer, antistatic polyvinyl chloride layer, Antistatic Nylon layer and anti-static polythene layer hot melt from outside to inside successively.
Antistatic polyester layer is PC layer 1, it is the amorphous polymer of water white glassy state, there is excellent heat resistance, within the scope of wider epidemic disaster, all there is good and constant electrical insulating property, ensure that peripheral electrostatic field cannot through bag 6, better make the components and parts in bag and electrostatic field isolation, avoid electrostatic field and the electronic devices and components in bag 6 are had an impact.Its thickness is preferably 10 μm.
Meanwhile, it also has good anti-flammability and stability, and this is for the important spare part aspect in higher electronic devices and components, the particularly computer etc. of element precision requirement, forms a well protection.
Certainly, the antistatic oxidant layer 5 in side can also be set up on PC layer 1, as vistanex etc., the effect of antistatic can be made so better.Can also a Self-enclosing structure 7 be set on PC layer 1, as Fig. 1, can also prevents the electronic devices and components in bag from skidding off from bag like this.
Antistatic polyvinyl chloride layer is layer of PVC 2; polyvinyl chloride have fire-retardant (fire-retardant value is more than 40), chemical proofing high (resistance to concentrated hydrochloric acid, concentration be 90% sulfuric acid, concentration be the nitric acid of 60% and the NaOH of concentration 20%), mechanical strength and the good advantage of electrical insulating property; the existence of layer of PVC 2, can play a very good protection to the electronic devices and components in bag.Its thickness is preferably 8 μm.
Antistatic Nylon layer is transparent PA layer 3, there is the performances such as good hot strength, impact strength, rigidity, wearability, chemical resistance, case hardness, light transmittance is high, while whole bag 6 intensity of enhancing, also can not affect and recognize the observation of electronic devices and components in bag.Its thickness is preferably 8 μm.
Anti-static polythene layer is PE layer 4, and it has the feature of quick acting, antistatic time length, and dielectric loss is low, dielectric strength large, both can do frequency modulation insulating materials, corona resistance plastics, and can do high voltage insulating materials again.Its thickness is preferably 10 μm.
The mode of above-mentioned heat-sealing all adopts EVA PUR to fit, EVA hot-melt adhesive cohesiveness is large, melt surface tension force is little, hot glue relay is all had to nearly all material, and there is excellent resistance to chemical reagents, heat endurance, weatherability and electric property, bonding rapidly, wide application, nonhazardous, the feature such as pollution-free.
The four-layer structure of this sack uniqueness can form inductive effect and isolate with electronic devices and components in protective bag and electrostatic field; and the inside one deck is by the polyethylene layer can eliminating electrostatic; effectively prevent from producing electrostatic in bag, can better protect electric sensitive components to endanger from potential electrometer.
In addition, the sack after this heat-sealing is translucent, just can know recognition interior items from the outside, does not need dismounting even to destroy sack to observe, recognizes, and sheet resistance value can reach 10 power Ω of 8 power Ω ~ 10 of 10.
The above is only preferred embodiment of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technical schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
