Abstract
The invention discloses a ceramic filter material and a preparation method thereof. The preparation method comprises the following steps of: pretreating ceramic fibers; modifying the pretreated ceramic fibers; lapping the modified ceramic fibers on a lapping machine to form a ceramic fiber mesh; spraying high-silica fibers into a high-silica melt-blown fiber mesh by virtue of a melt-blowing device; then spinning at least one ceramic fiber mesh on a conveyor belt, melt-blowing multiple high-silica melt-blown fiber layers with the crystallinity of 30-50% on the ceramic fiber mesh by adopting the high-silica melt-blown fiber mesh, and then carrying out hot pressing on the used ceramic fiber mesh to form multiple layers until diameter of the ceramic filter material is more than 0.5mm; and finally pressing and connecting for carrying out integrated forming by adopting a plain roller.
Description
Technical field
The present invention relates to a kind of Environmental-protecting dust-removing filtering material and preparation method thereof, particularly relate to a kind of ceramic filter material and system thereof
Preparation Method.
Background technology
Ceramic fibre is a kind of fibrous light refractory material, has lightweight, high temperature resistant, Heat stability is good, thermal conductivity
Low, specific heat is little and the advantage such as mechanical resistant vibrations, thus in the industry such as machinery, metallurgy, chemical industry, oil, pottery, glass, electronics all
Being widely used, its light weight, heat-insulating property are good, Heat stability is good, chemical stability are good, handling ease, construction party
Just.The most wear-resisting the most not impact resistant, it is impossible to washing away of opposing high velocity air, it is impossible to the erosion of opposing slag.
It is higher that resurrection glass fibre layer includes silicon dioxide, and silicon dioxide at high temperature has higher viscosity, melted
Liquid film have opposing high temperature gas flow impact capacity.
Summary of the invention
The purpose of the present invention is that to provide to solve the problems referred to above and a kind of can resist the washing away of high velocity air, supports
The ceramic fibre filtrate of the erosion of slag-resistant.
To achieve these goals, the present invention is achieved by the following technical solutions: a kind of ceramic filter material and preparation thereof
Method, it includes:
1) ceramic fibre is carried out pretreatment；
2) it is modified pretreated ceramic fibre processing；
3) lapping on lapping machine of the ceramic fibre after modification is become ceramic fibre net；
4) high silica fiber is sprayed into high silica meltblown fiber web through device for melt blowing；
5) then least one layer of ceramic fibre net is spinned on a moving belt, use high silica meltblown fibers Netcom thereon
Cross meltblown by after the high melt-blown multilamellar of silica meltblown fibers of degree of crystallinity 30%-50%, after by the ceramic fibre net hot pressing that uses extremely
Multilamellar, until the diameter of ceramic filter material is more than 0.5mm；Plain-barreled roll crimping is finally used to carry out integrally-formed.
Further, described resurrection glass fibre layer processes through invading stain phenol resin solution.
Further, in described step 1), pretreatment includes that warm wash processes and sanding processes.
Further, the fibre diameter of described high silica meltblown fiber web is 5-10 μm；The fibre of described ceramic fibre net
Tie up a diameter of 30-50 μm.
Particularly, described step 2) in modification be that ceramic fibre is invaded stain and processed in mixed ethanol solution, described mixing
Ethanol solution be mol ratio be the solution that cyclodextrin and the carbimide of 1:7-8 is dissolved in ethanol.
The method have the advantages that the present invention passes through ceramic fibre and the long and slender dimension of vagcor in sum
Strengthening, light weight in the ceramic fibre filter structure obtained, heat-insulating property is good, Heat stability is good, chemical stability are good, processing is held
Easily, easy construction, make ceramic fibre have the erosion washing away, resisting slag that can resist high velocity air simultaneously.
