Abstract

The invention discloses an electret plastic food preservation box which is characterized in that fluoroplastic is processed into microporous material, food preservation boxes with different styles and different specifications are obtained by the injection molding technology, and electret technologies such as a corona method, a breakdown method and the like are adopted for treatment. The electret food preservation box is antibacterial, dustproof and waterproof, nontoxic and harmless, safe and reliable and low-carbon, environment-friendly and energy-saving, and has good air permeability, long preservation time and high preservation degree, thereby being a brand new food preservation box; and the electret food preservation box can be widely used for preserving food in families, hotels, shopping malls, and industries of travel, fast food and the like.

Description

Electret plastic-food crisper

Technical field

The present invention discloses a kind of food preserving box, is specifically related to a kind of food preserving box of being made by the fluoroplastic electret.

Background technology

Food a large amount of in the daily life need fresh-keeping depositing, though the food preserving box that uses at present has high-seal, the no leakage body, vapor tight function, but the environment of sealing makes food spoilage, spoiled also for bacterial reproduction provides condition, its fresh keeping time far is shorter than and is placed in the open container, because used food preserving box do not have fresh-keeping function, generally all adopts to be placed in the refrigerator fresh-keepingly, there is the problem that takies refrigerator space and the consumption energy.

Summary of the invention

The present invention discloses a kind of electret plastic-food crisper, has that permeability is good, dustproof and waterproof, sterilization bacteriostasis efficacy and fresh keeping time be long, the performance that freshness is high.

The technical scheme that technical solution problem of the present invention is taked is, fluoroplastic are processed into poromerics, and the food prepared therefrom crisper carries out electret and processes.

The fresh-keeping mechanism of electret plastic-food crisper is, the fluoroplastic electret is processed, the strong electrostatic field that exists on the fluoroplastic and little electric current, the cell membrane of damage bacterium, destroy the surface texture of bacterium, stimulate the bacterioprotein variation, cause bacterium dead, and the breeding of each bacterioid is had obvious inhibit function; Strong electrostatic field also ionized air produces ion-atmosphere and ozone, and negative ion has the metabolism of the food of inhibition, slows down the active function of enzyme, and ozone is a kind of strong oxidizer, has the effect of sterilization sterilization ability and fresh air, elimination peculiar smell.

Fluoroplastic are polarization and energy longer-term storage electric charge under the effect of the factors such as strong external electric field, has electrostatic field and little electric current in the electret plastics.Arrange from many micropores at the electret plastics, the similar numerous passive collecting electrode of micropore, when airborne charged corpuscle especially submicron particle passes through these holes, be blocked or catch under the effect of electric field force and little electric current, airborne neutral corpuscle becomes dipole and is also stopped by actv. because of induction or polarization.Bacterium and germ have natural electret state (electronegative) and usually are attached on the airborne dust, scatter and propagate with Air Flow, be attached to the surface of food, when they in the environment of negative ion that the strong electrostatic field that the electret plastics produce, little electric current and ionized air produce, ozone, cause bacterium death and can't breed, negative ion and ozone also suppress the metabolism of food, slow down the active function of enzyme, make the freshness of food higher, fresh keeping time is longer.

Described electret food preserving box is that fluoroplastic are processed into poromerics, adopts Shooting Technique to be processed into food preserving box, adopts electret to process.The micropore quantity of electret plastics is that every square millimeter is more than 1,000 ten thousand, micro-pore diameter is at 0.1-0.5 μ m, this diameter is the 1/2000-1/5000 of drop diameter, 700 times of water vapour molecule, the moisture of outside can not infiltrate, the aqueous vapor of the generation of food and heat can appear by micropore, be not gathered in the food box, when being 3000V-4000V, stabile current can reach 98.5% to colibacillary eradicative rate, eradicative rate to bacteriums such as salmonellas reaches 88.7%, strong electrostatic field, the air that little electric current also ionizes in the food preserving box produces negative ion, ozone, eliminate the peculiar smell that food produces in depositing process, the electret plastics also have acidproof, alkaline-resisting, high temperature resistant, do not corroded, nontoxic, safe and reliable characteristic.

These described fluoroplastic comprise perfluoro second propylene, polytetrafluoroethylene, ethylene-tetrafluoroethylene copolymer etc., or the composite processing of polytetrafluoroethylene and perfluoro second propylene is made the electret plastics.

Described electret is processed electret technology such as adopting corona method or Breakdown Method.

The invention has the beneficial effects as follows, the electret food preserving box has antibacterial bacteriostatic, dustproof and waterproof, good permeability, fresh keeping time is long, freshness is high effect, fresh-keeping effect to food is much better than present food preserving box, the electret plastic preserving box has nontoxic, safe and reliable characteristic, low-carbon environment-friendly is energy-conservation, is a kind of brand-new food preserving box, also is the regeneration product of present food preserving box.

Description of drawings

Accompanying drawing is electret food preserving box schematic diagram of the present invention.

The specific embodiment

The present invention is further described below in conjunction with drawings and Examples.

As shown in drawings, fluoroplastic are processed into cellular plastic, the thickness of food preserving box wall, lid is at 2mm-5mm, micropore quantity is that every square millimeter is more than 1,000 ten thousand, micro-pore diameter is at 0.1-0.5 μ m, adopt Shooting Technique to be processed into different styles, the food preserving box of different size adopts the electret technical finesses such as corona method or Breakdown Method.

Electret food preserving box of the present invention, has antibacterial bacteriostatic, dustproof and waterproof, the characteristic of good permeability, the bacteriums such as the Escherichia coli that cause food spoilage, salmonella had very strong killing and the inhibition performance, prolong fresh keeping time and the freshness of food, can be widely used in the industry food fresh keepings such as family, hotel, market and tourism, fast food and use.
