Description
Technical field
The invention belongs to fire resisting material field, relate to a kind of energy-saving heat-insulating lining material and preparation method thereof, be widely used in each thermal kiln furnace industry.
Background technology
Energy shortage is the reality of the world today, and save energy is the important tasks in various countries, and under this form, energy-saving lining is mathematical to the importance of modern industry kiln.Traditional Industrial Stoves are the purpose that reaches heat preservation energy-saving, usually in heavy refractory brick is built body or heavy unshape refractory construction body by laying bricks or stones or outside increase thermal insulation layer, but the heavy layer has strengthened bulky kiln to bear a heavy burden, and for batch furnace, the accumulation of heat loss is big especially.
Summary of the invention
The objective of the invention is concrete working condition, provide a kind of volume density at 700 ± 30kg/m at various thermal kiln furnaces
3In the scope, thermal conductivity is low, intensity is high, the insulated lining material of high insulating effect.
Energy-conservation lining is meant and does not readily conduct heat, hot-fluid is had the single-material or the matrix material of remarkable impedance behavior.The characteristics that energy-conservation lining possesses are: volume density is little; Thermal conductivity is low; Furnace lining intensity height increases than ceramic fiber material on resistance to compression and anti-airflow scouring ability; Constructional method can adopt and smear, pouring type, and is convenient and swift and pollution-free.Applicable Thermal Equipment of energy-conservation lining and occasion are:
*The various Fuel Furnace furnace linings (furnace wall and furnace roof) of working temperature≤1250 ℃;
*The backing thermal insulation layer (furnace wall and furnace roof) of various High-temp. kiln interface temperatures≤1050 ℃;
*Industrial Boiler furnace roof lining;
*The resistance furnace lining of working temperature≤1200 ℃;
A kind of 700kg class energy-saving heat insulation lining material and preparation method thereof, it is characterized in that at first carrying out the apolegamy of matrix starting material, the employing haydite is an aggregate, with perlite, big vast mountain soil and pure calcium aluminate cement is that matrix is formed, and is that tripoly phosphate sodium STPP, Sodium hexametaphosphate 99 are added in addition as water reducer and dispersion agent in the basis with the matrix material.
Its matrix material is pressed the preparation of column weight amount per-cent:
Crude pottery grain (particle diameter 3-5mm) 7-12%
Middle haydite (particle diameter 1-3mm) 4-8%
Thin haydite (particle diameter 0-1mm) 3-7%
Thick perlite (particle diameter 1-3mm) 7-11%
Middle perlite (particle diameter 0.3-0.6mm) 10-14%
Oyster pearl rock (particle diameter 0.125-0.18mm) 15-18%
Flood mountain soil 6-8%
Pure calcium aluminate cement 34-36%
The add-on weight percent of tripoly phosphate sodium STPP, Sodium hexametaphosphate 99 is
Tripoly phosphate sodium STPP 0.1-0.2%
Sodium hexametaphosphate 99 0.05-0.1%
After raw material was selected, its preparation technology was: earlier pure calcium aluminate cement and tripoly phosphate sodium STPP, Sodium hexametaphosphate 99 are put into the twin-shaft mixer pre-mixing and evenly make premix A, be packaged into pouch afterwards; After in mixer, haydite, perlite, big vast mountain soil being mixed then, the sack of packing into; At last pouch is put into and promptly finished after sack seals.In the job location, will put in order bag material, comprise the premix A in the pouch, all put into forced stirrer, pre-mixing once more adds water and stirred 3～5 minutes after mixing, and to pour mould into be position to be cast to the material that will stir afterwards, or directly smear construction.After the natural curing 48 hours, can carry out baking processing.
Energy-conservation lining by the inventive method preparation is compared with traditional lightweight heat-proof lining material, and its excellent performance mainly shows on thermal conductivity and the intensity.
1. the thermal conductivity of energy-conservation lining is lower, according to refractory materials thermal conductivity test method (discharge flat band method) YB/4130-2005, recording energy-conservation lining is 0.12W/ (mK) 350 ℃ thermal conductivity, and common lightweight heat-proof lining is 350 ℃ thermal conductivity (SH/T3115/2000 standard) more than 0.17W/ (mK).Energy-conservation like this lining just has better heat insulating effect, and more effective cutting down the consumption of energy saved a large amount of energy.
2. the intensity of energy-conservation lining is higher, according to density fireproof mould material strength at normal temperature and compressive strength test method YB/T 5201-1993, recording 110 ℃ of oven dry of energy-conservation lining compressive strength is 2.5MPa, and 2.2MPa increases with respect to the traditional lightweight insulated lining.Like this, use energy-conservation lining just can prolong work-ing life of thermal kiln furnace furnace lining material, for the user has reduced thermal kiln furnace running cost.
