Antistatic heat-insulating aluminum film bag

Abstract

The invention discloses an antistatic heat-insulating aluminum film bag. The antistatic heat-insulating aluminum film bag comprises a bag body; from outside to inside, the bag body comprises a sunscreen shell fabric layer, a thermal dispersing thermal insulating shell fabric layer, an aluminum film layer, and a supporting layer successively; the sunscreen shell fabric layer is prepared via blending and knitting of polyester fiber and mulberry silk fiber; the thermal dispersing thermal insulating shell fabric layer is prepared via blending and knitting of tencel fiber and flax fiber; the support layer comprises a metal layer and a textile fabric used for covering the surface of the metal layer; the textile fabric is prepared via sewing of an antistatic knitted cloth; the antistatic knitted cloth is prepared via weaving of monofilament spandex and anti-static fiber. According to a preparation method, the shielding bag possesses excellent thermal insulating effect via adopting of sunscreen shell fabric and the thermal dispersing thermal insulating shell fabric; and the supporting layer is used for effectively solving problems that static is generated in storage and transportation processes, and structural strength of the shielding bag is low. Environmental adaptive capacity of the antistatic heat-insulating aluminum film bag is excellent; application range is wide; and the antistatic heat-insulating aluminum film bag is capable of adapting different processing environment preferably.

Description

technical field [0001] The invention specifically relates to an antistatic heat-insulating aluminum film bag. Background technique [0002] At present, there are more and more applications of electronic products. Due to the complex structure of electronic components, they are easily damaged by static electricity and water vapor molecules in the process of circulation and use. The lighter ones will cause the electrical parameters of electronic components to drift and shorten the life. In severe cases, the components will fail completely, the circuit of integrated circuit components will be reduced, the withstand voltage will be reduced, and the circuit area will be reduced, which will weaken the device's ability to withstand electrostatic shocks. Electrostatic electric fields and electrostatic currents will become the fatal killers of these high-density components. The widespread application of a large number of plastic products and other high-insulation materials has greatly...

Problems solved by technology

[0004] 1. Static electricity absorbs dust, changes the impedance of line parts, and affects the function and life of the product;

[0005] 2. The insulation or conductor of the component is damaged due to the electric field or current, so that the component cannot work;

[0006] 3. Due to the heat generated by the instantaneous electric field or current, the component is injured, but it can still work and the life span is damaged

[0008] 1. Concealment, the human body cannot directly perceive static electricity unless electrostatic discharge occurs, but the human body may not feel an electric shock when electrostatic discharge occurs, because the electrostatic discharge voltage perceived by the human body is 2-3KV;

[0009] 2. Latency, the performance of some electronic components does not decline significantly after being damaged by static electricity, but multiple cumulative discharges will cause internal damage to the device and form hidden dangers, and increase the sensitivity of the device to static electricity. Any method can be solved;

[0010] 3. Randomness, under what circumstances will electronic components be damaged by static electricity? It can be said that from the time a component is produced until it is damaged, all processes will be threatened by static electricity, and the generation of these static electricity is also random. Sex, because the generation and discharge of static electricity occur instantaneously, and it is difficult to predict and protect;

[0011] 4. Complexity, electrostatic discharge damage, sub-board work, time-consuming, time-consuming, and expensive due to the fine and small structural characteristics of electronic products, requiring more complex technologies often require the use of precision instruments such as scanning electron microscopes, even so there are some electrostatic damage phenomena It is also difficult to distinguish from the damage caused by other reasons, which makes people mistakenly regard the failure of electrostatic damage as other failure. real cause of failure

[0012] In response to the above problems, there has been an antistatic aluminum film bag, which includes a main body layer, an antistatic outer layer fixedly connected to the outside of the main body layer, and an antistatic inner layer fixedly connected to the inside of the main body layer, wherein the main body layer is usually two The outer layer is a polyester metal layer, and the second layer is a PE polyethylene layer. Due to the existence of the inner and outer anti-static layers, the packaging bag can effectively prevent static damage and has the function of anti-static, but the above-mentioned anti-static There are still big defects in other properties of anti-static bags made of electrostatic film
