Abstract

The present invention is HEPA filters with exempting from discounting tree lace formula filter structure and its manufacture method, its structure includes filter screen skeleton and electrostatic electret airstrainer, wherein filter screen skeleton is in " W " shape, and electrostatic electret airstrainer is compounded in filter screen skeleton surface by ultrasonic wave point and shaped by glue.Its manufacture method includes：1) skeleton raw material manufacture filter screen skeleton is chosen；2) filter screen skeleton is given a discount as " W " shape and carries out heating pre-setting；3) ultrasonic wave point Combined Electrostatic electret airstrainer is passed through on " W " shape filter screen skeleton surface；4) gluing sizing is carried out to " W " the shape filter screen skeleton for being compounded with electrostatic electret airstrainer, obtains HEPA filters with exempting from discounting tree lace formula filter structure.Advantages of the present invention：Without core filtering material being given a discount and being heated pre-setting, avoid and the filter efficiency and windage of electrostatic filter material are impacted, ensure that overall filter effect, realize high-efficiency low-resistance.

Description

HEPA filters are with exempting from discounting tree lace formula filter structure and its manufacture method
Technical field
The present invention relates to HEPA filters with exempting from discounting tree lace formula filter structure and its manufacture method.
Background technology
HEPA (High efficiency particulate air Filter), i.e. high efficiency particle air filter, reach The filter screen of HEPA standards, reach 99.998%, HEPA filter screens for the filtering effective percentage of 0.1 μm and 0.3 μm of particulate pollutant The characteristics of be that air can be by, but tiny particulate can not be by being that the pollutants such as smog, dust and bacterium are most effective Filtering medium.HEPA is internationally recognized most efficient filtering material, and it is real to be widely used in operating room, Animal Lab., crystal Test with the air conditioning terminal air-supply in the high-cleanness place such as aviation.
Prior art during HEPA filters are produced, be required for screen material carry out give a discount heating pre-setting and Upper tree lace is shaped twice core process, wherein the heating pre-setting that gives a discount to the filter efficiency and windage effect of electrostatic filter material very Greatly, and then the overall filter effect of HEPA filters can be influenceed.
The content of the invention
Proposed by the present invention is that HEPA filters are intended to discounting tree lace formula filter structure and its manufacture method, its purpose is exempted from Overcome deficiencies of the prior art, exempt discounting and the heating pre-setting of core filtering material, realize HEPA filterings The high-efficiency low-resistance of device.
The technical solution of the present invention：HEPA filters include filter screen with discounting tree lace formula filter structure, its structure is exempted from Skeleton and electrostatic electret airstrainer, wherein filter screen skeleton are in " W " shape, and electrostatic electret airstrainer is answered by ultrasonic wave point Close on filter screen skeleton surface and shaped by glue.
Preferably, described filter screen skeleton is PP skeletons, ABS skeletons, PE skeletons, PVC skeletons or acrylic skeleton.
Preferably, the cell structure that described filter screen skeleton is formed in one.
The HEPA filters manufacture method for exempting from discounting tree lace formula filter structure, this method comprise the following steps that：
1) skeleton raw material manufacture filter screen skeleton is chosen；
2) filter screen skeleton is given a discount as " W " shape and carries out heating pre-setting；
3) ultrasonic wave point Combined Electrostatic electret airstrainer is passed through on " W " shape filter screen skeleton surface；
4) gluing sizing is carried out to " W " the shape filter screen skeleton for being compounded with electrostatic electret airstrainer, obtains HEPA filterings Device is with exempting from discounting tree lace formula filter structure.
Preferably, described skeleton raw material is PP, ABS, PE, PVC or acrylic.
Preferably, the cell structure that described filter screen skeleton is formed in one.
Advantages of the present invention：Production technology has been innovated, without core filtering material being given a discount and being heated pre-setting, has been kept away Exempt to impact the filter efficiency and windage of electrostatic filter material, ensure that the overall filter effect of HEPA filters, realize The high-efficiency low-resistances of HEPA filters.
