Abstract
The invention relates to a PTFE special filter material air filter, which comprises a rectangular outer frame body enclosed by aluminum profile. The aluminum profile consists of an upper profile, a lower profile and a connecting plate supporting the upper profile and the lower profile. A PTFE filter core wrapped by a steel screen plate is placed on the lower profile, polyurethane rubber fixing the PTFE filter core fills the blank between the upper profile and the lower profile, and ethylene-propylene-diene monomer sealing gaskets are disposed above and below the outer frame body. The structure of the PTFE special filter material air filter is compact, light and thin, is not flooded with water, can be applicable to high humidity environments, is resistant to acid-base and organic solvent corrosion, and is resistant to ultraviolet irradiation. And the filter paper strength is higher, thus having higher bearing capacity for collision in the process of transportation and installation.
Description
Technical field:
The present invention relates to air cleaning facility, especially a kind of PTFE special filter air filter.
Background technology:
Now, semiconductor chip factory is the most fastidious to production environment air cleaning degree, and the requirement to air filter is the harshest.
The dust being bonded on chip be likely to result in open circuit, short circuit and directly affect yield rate, therefore chip factory is taken notice of on filter especially
Possible trace volatile element.In order to be satisfied with the chip factory of semi-conductor industry, medelling toilet and microenvironment for air
The strict demand purified.
Summary of the invention:
For above technical problem, the present invention devises a kind of PTFE special filter air filter, surrounds including by aluminium section bar
Rectangular outer frame body, described aluminium section bar includes the connecting plate of upper sectional material, lower sectional material and support upper sectional material and lower sectional material, described mo(u)ld bottom half
Place the PTFE filter element wrapped up by steel net plate on material, between upper sectional material and lower sectional material, fill the polyurethane of fixing PTFE filter element
Glue, is both provided with EPT rubber packing pad above and below described outer frame body, for this air filter and FFU, peace
Sealing between keel.
For stable outer frame body structure, further: the outside of described upper sectional material and lower sectional material is all correspondingly arranged on for even
The elongated slot that fishplate bar inserts, and by screw, upper sectional material, lower sectional material are fixed with connecting plate.
In order to strengthen the bulk strength of the intensity of filter element, yet further: the most logical between the every discharging the retained water of filter paper of PTFE filter element
Cross PUR to fix.
In order to ensure to be located just in outer frame body, yet further by PTFE filter element: the length of described PTFE filter element and
Width is less than the length and width outside outer frame body.
Compared with prior art, usefulness of the present invention is: with PTFE overlay film be filtrate make high efficiency particulate air filter, this
Kind material, compared with glass fibre high efficiency particulate air filter, has extremely low chemical gas Disseminated (the most siliceous, boron)；Structure is tight
Gather, light, thin；Do not soak, it is adaptable to the environment that humidity is higher；Antiacid alkali and organic solvent corrosion, UV resistant irradiates；Filter paper is strong
Du Genggao, has higher holding capacity to the collision in transport and installation process；With same air quantity, the glass fiber filter of same specification
Comparing, its initial resistance greatly reduces the energy consumption of supply air system about being at half.
Accompanying drawing illustrates:
The present invention is further described below in conjunction with the accompanying drawings.

Detailed description of the invention:
A kind of PTFE special filter air filter as shown in Figure 1, Figure 2 and Figure 3, including the rectangle surrounded by aluminium section bar 2 outside
Framework 1, described aluminium section bar 2 includes upper sectional material 21, lower sectional material 22 and supports the connecting plate 23 of upper sectional material 21 and lower sectional material 22, described
Place the PTFE filter element 3 wrapped up by steel net plate 4 on lower sectional material 22, between upper sectional material 21 and lower sectional material 22, fill fixing PTFE filter
The polyurethane adhesive 5 of core 3, is both provided with EPT rubber packing pad 6 above and below described outer frame body 1, for this air
Sealing between filter and FFU, installation Os Draconis.
It addition, for stable outer frame body 1 structure, the outside of described upper sectional material 21 and lower sectional material 22 is all correspondingly arranged on for even
The elongated slot 24 that fishplate bar 23 inserts, and by screw, upper sectional material 21, lower sectional material 22 are fixed with connecting plate 23.
In order to ensure to be located just in outer frame body 1 by PTFE filter element 3, the length and width of described PTFE filter element 3 is less than
Length and width outside outer frame body 1.
In order to strengthen the bulk strength of the intensity of filter element, between the every discharging the retained water of filter paper of PTFE filter element 3, all pass through PUR 7 line
Fixing.Collision in transport and installation process there is higher holding capacity.
It is emphasized that: be the most only presently preferred embodiments of the present invention, not the present invention is made any in form
Restriction, any simple modification, equivalent variations and the modification that above example is made by every technical spirit according to the present invention,
All still fall within the range of technical solution of the present invention.
