Abstract

The invention discloses a kind of silica paper and screen pack thereof, silica paper is that raw material is made by powdered silica, polyster fibre, adhesive; Screen pack comprises platen surface, adhesion corrugation tooth in platen surface, and corrugation tooth both sides adhesion bound edge, described platen surface, corrugation tooth, bound edge all adopt silica paper to make.Inventive silica paper has the function of the pernicious gas such as formaldehyde adsorption, benzene, the removal efficiency of the pernicious gases such as corresponding filter paper and screen pack PARA FORMALDEHYDE PRILLS(91,95), benzene is remarkable, and be comparatively usually used in the active carbon of air purification field, except absorption property does not subtract, also have clean attractive in appearance, be easier to by advantages such as consumers in general accept.Can be used alone or support the use with active carbon goods.

Description

Silica paper and screen pack thereof

Technical field

The present invention relates to a kind of can the effective functional filter paper of the pernicious gas such as formaldehyde, benzene in absorbed air, and with the corrugated screen pack that this paper is made into, be applied to the main components of high efficiency particulate air filter.

Background technology

Silica is had many uses, and be exactly silica by the fibre-optic primary raw material of high-performance communication material used at present, it is the vitals manufacturing electronics industry, is also used for manufacturing resistant to elevated temperatures chemical apparatuses, frit and construction material etc.But, rarely have silica for air purification field.

Existing air cleaning unit screen pack, the general absorbent charcoal material that adopts is made.

Summary of the invention

The object of the present invention is to provide a kind of clean attractive in appearance, the silica paper of favorable working performance and screen pack thereof.

Technical solution of the present invention is:

A kind of silica paper, is characterized in that: be made up of the raw material of following weight percents:

Powdered silica 65 ~ 75%

Polyster fibre 15 ~ 25%

Adhesive 10 ~ 15%.

The screen pack that silica paper is made, comprises platen surface, adhesion corrugation tooth in platen surface, and corrugation tooth both sides adhesion bound edge, is characterized in that: described platen surface, corrugation tooth, bound edge all adopt silica paper to make.

Inventive silica paper has the function of the pernicious gas such as formaldehyde adsorption, benzene, the removal efficiency of the pernicious gases such as corresponding filter paper and screen pack PARA FORMALDEHYDE PRILLS(91,95), benzene is remarkable, and be comparatively usually used in the active carbon of air purification field, except absorption property does not subtract, also have clean attractive in appearance, be easier to by advantages such as consumers in general accept.Can be used alone or support the use with active carbon goods, having filled up use silica as the raw-material blank of purification of air.According to test result: silica paper screen pack 24 hours formaldehyde clearances reach 62%, and within 24 hours, benzene clearance reaches 53%.

Detailed description of the invention

Embodiment 1:

A kind of silica paper, be made up of the raw material of following weight percents:

Powdered silica 65 ~ 75%(example 65%, 70%, 75%)

Polyster fibre 15 ~ 25%(example 15%, 20%, 25%)

Adhesive (EVA glue) 10 ~ 15%.(example 10%, 12%, 15%)

Above-mentioned raw materials consumption sum is 100%.

After being mixed by above-mentioned raw materials, net sizing is once become to form silica paper on a papermaking machine.

Embodiment 2:

The corrugation tooth of band platen surface is made in silica paper pressure rolling embodiment 1 obtained, again by stacked for the corrugation tooth of multiple band platen surface, corrugation flank adhesion bound edge, makes screen pack, be installed in the air purifier of drive device, reach the object removing pernicious gas in air.

Claims (2)

1. a silica paper, is characterized in that: be made up of the raw material of following weight percents:
