Description
Technical field
The present invention relates to a kind of method of utilizing of basalt fibre, relate generally to a kind of preparation method of basalt fiber furnace lining module.
Background technology
In the liner of waste heat boiler, still use the aluminum silicate fiber module at present, its corrosion resistance nature is general.And the thermal source of waste heat boiler is industrial gaseous waste, contains a large amount of carbonic acid gas and sulfurous gas, and these materials have stronger acid attack ability, so its life-span only had about 6 months.
Aluminum silicate fiber module commonly used contains the slag ball about 20%, and its fiber is different in size, its structure absent-mindedness, and needling density is little, causes greatly reduce work-ing life.
Basalt fibre, be the basalt building stones after 1450 ℃～1500 ℃ meltings, the continuous fibre that forms by platinum rhodium bushing high speed pulling.Be similar to glass fibre, its performance is between high strength S glass fibre and alkali-free E glass fibre, and the color of pure natural basalt fibre is generally brown, and some is like golden.
The hi-tech Fiber Phase ratios such as basalt fibre and carbon fiber, aramid fiber, superhigh molecular weight polyethylene fibers (UHMWPE), except the characteristics with hi-tech fiber high-strength degree, high-modulus, the excellent properties such as basalt fibre has also that high thermal resistance is good, anti-oxidant, radioprotective, adiabatic sound insulation, good, the incompressible intensity of filterableness and shearing resistance are high, be adapted to use under the various environment, and cost performance is good, being a kind of ceramic of pure natural, also is a kind of new base mateiral and hi-tech fiber that can satisfy the infrastructural industry for the national economy growth requirement.
Basalt fibre and matrix material thereof can satisfy the demand of the field structure materials such as national defense construction, communications and transportation, building, petrochemical complex, environmental protection, electronics, Aeronautics and Astronautics preferably, and national defense construction, Important Project and industrial structure upgrading are had important pushing effect.It is the green material that meets the ecotope requirement 21 century, is again the competitive new material industry of a Sustainable development in the World High Technology fiber industry.Especially China has had basalt fibre manufacturing technology and the technique of independent intellectual property right, and the rear advantages for development with " catching up from behind " have reached the leading level in the world, therefore, greatly develop basalt fibre and the matrix material industry has great importance undoubtedly.
Basalt fibre adopts natural volcanic rock raw material fully, and its chemical stability is very superior, and very strong acid-proof alkaline is arranged.Compare with the module of other fibre products such as glass fibre, aluminum silicate fiber, its acidity quotient is greater than 2, and contain basic flux such as Wingdale, rhombspar etc. in glass fibre and the aluminum silicate fiber, its acidity quotient is less than 1.7, therefore, the acid-alkali-corrosive-resisting performance of basalt fibre is better than other fibrous modules.(acidity quotient is the important indicator of weighing the goods corrosion resistance:
Acidity quotient
Summary of the invention
The object of the invention is to overcome above-mentioned weak point, a kind of preparation method of basalt fiber furnace lining module is provided, its product has good heat-resisting effect as industrial furnace and waste heat boiler liner.
According to technical scheme provided by the invention, a kind of preparation method of basalt fiber furnace lining module, step is as follows:
(1) chopped: as to get basalt fibre chopped on fibre chopping machine; The cutter edge width is 400～800mm, charging thickness 30～80mm;
(2) shredding: get the basalt fibre shredding on teaser after chopped, to basalt fibre density be 2.6～3.05kg/m
3
(3) combing lapping: take away the basalt fibre carding assembly single-fiber state on carding machine behind the pine, assemble again the basalt fibre net;
(4) acupuncture: get the basalt fibre net and send into and carry out acupuncture in the needle loom, sneak into the high-shrinkage fibre of ratio 10%～20%, then under 100～120 ℃ water vapour, process 20～30min;
(5) cutting: the basalt fibre net of getting after the acupuncture cuts into desired shape;
(6) WATER REPELLENT: the waterproof paint after the basalt fibre of cutting gained is coated with one deck 1～5mm on the net; Air drying folded afterwards bulk in 1～2 day and namely gets the product basalt fiber furnace lining module.
Described waterproof paint is polyurethane water-proof paint or ACRYLIC EMULSION waterproof paint.
The present invention has following advantage: the basalt fibre liner block of the present invention's preparation is a kind of novel industrial furnace furnace lining goods, traditional industrial furnace furnace binding and constructional method have been broken through, its insulating refractory effect is 5～8 times of traditional firebrick structure, greatly save energy consumption.The furnace wall structure weight of being built by laying bricks or stones by the basalt liner block only is 1/5 of traditional firebrick structure, has greatly alleviated the weight of industrial furnace.Especially heat conductivility is outstanding, has greatly shortened the time of industrial furnace intensification operation.
