Description
Technical field
The present invention relates to a kind of manufacture method of carbon fibre regular corrugation filler, belong to the manufacturing technology of high-performance filler.
Background technology
In departments such as petrochemical industry, fine chemistry industry, light industry, food, pharmacy, environmental protection and atomic energy, packed tower is indispensable visual plant, is widely used in unit processes in chemical synthesis such as distillation, absorption, washing, cooling.Packed tower is compared with plate column has outstanding features such as flux is big, efficient is high, pressure is little.Use the old plate column of high efficiency packing technological transformation, generally can make output improve 30-100%, energy consumption reduces 20-50%, and properties of product are obviously improved.In recent years, the appearance of novel packed tower and the successful Application in main equipment have obtained huge economic benefit and social benefit in China.
Filler (being divided into dumped packing and structured packing) is the core component of packed tower, and it has determined the performance of packed tower with tower internals.Filler provides the surface of gas-liquid two-phase contact mass transfer and heat exchange.Because the progress of industrial technology, production scale maximizes, and requires tower to have big flux, and liquid is evenly distributed, and reduces the packing layer resistance, improves separative efficiency, reaches energy-saving effect.Structured packing can be satisfied the requirement of major diameter tower, and therefore the development of all kinds of structured packings is rapid.Compare with dumped packing, structured packing can be arranged more large tracts of land, does not almost have enlarge-effect, compound with regular structure, and the efficient height, energy-saving effect is remarkable.
By the material classification, structured packing comprises metal, plastics, pottery etc.
Above-mentioned various filler in strong corrosive medium, particularly hydrofluoric acid, chloric acid, formic acid, acetate, monoxone, etc. poor corrosion resistance, life cycle is short, causes the waste that causes resource, and the cost of producing product is improved.
Summary of the invention
The object of the present invention is to provide a kind of preparation method of carbon fibre regular corrugation filler.Regular corrugation filler with this method manufacturing has the strong corrosion resistant performance, can be suitable for working under various corrosive medium conditions.
The present invention is realized by following technical proposals.A kind of preparation method of carbon fibre regular corrugation filler is characterized in that comprising following process:
(1) with the diameter is 7-9 μ m, every bundle carbon fiber is 4000,6000 or 8000, polyacrylonitrile-based carbon fibre is a raw material, adopts through compiling multi-axial fabric technology or woven technology, and it is the carbon cloth of 0.1-0.35mm that carbon fiber knit is become 20-40 purpose carbon fibre web or thickness.
(2) step (1) is knitted carbon fibre web or carbon cloth carry out surface clean, decontamination with acetone and deionized water; Then in 400-500 ℃ of gaseous oxidation, drying; Dried carbon fibre web or carbon cloth are immersed among epoxy resin, BMI or the caprolactam resin that viscosity is 300-600cP, 10-30 minute; The carbon fibre web or the carbon cloth that are impregnated with resin are placed in the mould with ripple bar, solidify between 60-200 ℃, be 0.5-2 hour hardening time, forms carbon fiber ripple net or carbon fiber corrugated plating behind the holder mould.
(3) carbon fiber ripple net or the carbon fiber corrugated plating that step (2) is made places vacuum furnace, under 1-3KPa vacuum and nitrogen protection condition, with 5-10 ℃/min heating rate, rises to 950-1200 ℃ and gives carbonization, is incubated 2-5 hour, comes out of the stove after the cooling.
(4) ripple carbon fibre web or the ripple carbon fiber board that step (3) is made axially is mutually the rule of 90 ° of angles by the ripple of adjacent two ripple carbon fibre webs or ripple carbon fiber board, and ripple carbon fibre web or ripple carbon fiber board are assembled into the filler block.
The invention has the advantages that process conditions are easy to accurate control, carrier performance is easy to adjust.The specific area of modified carbon fiber structured packing is 350-1500m
2/ m
3, and mechanical property is not less than stainless steel and the netted porous aggregate of titanium alloy.Particularly outstanding is, the modified carbon fiber structured packing has free from corrosion substantially characteristic, can realize the high purity material manufacturing feasibility, thereby it is short to have overcome active time in the deep-etching tower such as titanium material, stainless steel, and shut-down (breakdown) mainteance is frequent, the shortcoming that resource consumption is high.
