Description
The present invention relates to a kind of infrared radiation heater prescription and technology of low-firing.
At present domestic and international ceramic-like infrared radiation heater, no matter be with aluminosilicate, quartzy, still to take the photograph English sand, silicon carbide is done the infrared radiation heater of base material, no matter how and producing apparatus and means its prescription, the making principle that does not all surmount pottery, utilize the plasticity-of clay when being moulding, various raw materials in the prescription are combined, make required different shape, carry out drying, enter in the high temperature kiln again and burn till, promptly allow these raw materials in high temperature kiln, carry out various physicochemical change, carry out the transformation and the regeneration of various crystal formations, make the raw material of moulding become grog, have certain machine,, thermal characteristics.Thus, just stipulated the formulation principle and the manufacturing process thereof of ceramic-like infrared radiation heater, product structure.Its maximum characteristics are, complex forming technology, and firing process is just more complicated, is difficult for grasping and control.
Prior art processes utilizes clay that other raw material is combined, and the clay drying shrinkage deformation is big, causes making relatively difficulty of complex product and big area product.The prior art products structure is also more single, can only make electrical heating element and matrix separated structures.Because of the firing temperature of matrix more than 1200 ℃, and the highest withstand temp of electrical heating element is about 1000 ℃.There is following defective in this structure: 1) installation of well heater is restricted, can not install with the setting of moving towards of electrical heating element, otherwise electrical heating element falls to burning well heater downwards after being heated.2) the well heater heating and cooling are slow, and this is because the well heater volume is big, heaviness, and it is many self to absorb heat, and electrical heating element contacts also not so good with matrix.3) electrical heating element is exposed in the air and heats, and is easily oxidized, and the life-span is not long, not too suitable to continuous heating target, because the electrical heating element life-span is too short, must not on-line maintenance, and be a kind of loss to the user.
Adopt prior art, the equipment one-time investment is bigger, high temperature kiln particularly, and cost is very high, and only 30 meters high chimneys just need more than 50,000 yuan.If the burning coal, the coal smoke that is discharged is a kind of serious pollution to atmosphere.
First purpose of the present invention provides a kind of prescription of infrared radiation heater of low-firing.
Second purpose of the present invention provides a kind of infrared radiation heater manufacture craft of low-firing.
Compared with prior art, advantage of the present invention and positively effect are significant, 1) moulding process of the present invention becomes very simple, does not need complicated machine and mould just plastic, and labor strength is low.For nonstandard product and big area product, it is very difficult finishing with existing technology, and processing method provided by the present invention makes products production much simple easily, and product percent of pass is also than prior art height.2) firing process of the present invention becomes simpler, does not need complicated calcining system, firing atmosphere, and sintering curve after product is sent into electric furnace, only needs one man operation, just can by the temperature rise curve controlled temperature of setting.The product scrap rate is extremely low in the sintering process.3) the production cycle shortens greatly.Fabrication cycle shortens greatly, makes same a collection of product, and prior art needs about eight days at least, and processing method provided by the invention at most only needs about 2 days.4) energy waste reduces greatly, and the firing time of method provided by the present invention had only about seven hours, comprises the coating time, and maximum sintering temperature has only 500 ℃, and the prior art firing time is 16～24 hours, and maximum sintering temperature reaches 1000 ℃～1300 ℃.And the energy consumption of 500 ℃～1300 ℃ of sections is more than three times of 20 ℃～500 ℃ of sections at least, and therefore using method provided by the present invention can save energy consumption about 3/4.5) form the equipment of producing in batches and simplify greatly, facility investment can significantly reduce, and uses method provided by the present invention, reach industrial scale same as the prior art, can reduce investment outlay more than 1/2.6) use the present invention, the structure of product becomes versatile and flexible, can make separate type according to user's needs product, also can make monoblock type, and this monoblock type infrared radiation heater has following advantage: a) quick heating, the time that arrives stabilized operating temperature is short.Because electrical heating element is implanted as one, electrical heating element has played the effect that strengthens product strength, makes matrix can do gentlier, and is thinner because of monoblock type, self absorb heat and just can reduce, and electrical heating element and matrix combined closely, and it is also faster to conduct heat.B) electrical heating element can prolong more than 5 times disposable work-ing life, because of the heating of electrical heating element secluding air.The prolongation in disposable work-ing life can reduce the number of times of maintenance of equipment, is very important for the continuous heating product of need.C) flames of anger is exposed, be suitable for inflammable, the use of explosive occasion.D) mounting means is unrestricted.7) abundant raw materials in the prescription provided by the present invention is easy to get, and low price can reduce product cost, enhances one's market competitiveness.8) through measuring, the infrared emittance of product is ε=0.91 in the time of 300 ℃, in the time of 400 ℃, and ε=0.86, the cold and hot insulation is measured through 1000VM Ω table, all more than 5M Ω.Product is put into electric furnace and is burnt to 1000 ℃ of furnace cooling, and cooling is again taken out again, does not ftracture for 5 times repeatedly.9) prescription provided by the present invention and processing method not only can be produced infrared radiation heater of high quality and at a reasonable price, also can produce other goods such as general purpose well heater and high temperature insulation.These products can be widely used in the heating, drying in the dry field of each heated baking, medical physiotherapeutic therapeutic device, electric-heating cooking utensil, electric heating apparatus, family, the hotel of industrial and agricultural production etc., or become heat-resisting, the insulating element of electromechanical equipment.
