Abstract
A method for processing a ceramic coating electric heating roller relates to the method for processing a heating ceramic material heating roller. A heating method of a product is very simple, and the heating is uniform and energy-saving. The method comprises the following main processing steps: 1) manufacturing a roller core; 2) coating a ceramic insulating layer; 3) coating a ceramic electric heating layer; and 4) surfacing, namely grinding an outside surface of the ceramic electric heating layer until roughness Ra is 0.80 to 0.025. The method is characterized in that: (1) the heating layer of the surface of the roller body is thinner, so the calorific capacity can be reduced, and the heating time can be shortened; (2) the heating layer is made of the ceramic material, the rigidity is proper and wearable, so the durability is excellent; and (3) uniform heating of the heating roller can be ensured only by strictly controlling a coating process and making the coated coating uniform. The method for heating the manufactured heating roller can effectively solve the problems of complex auxiliary equipment and nonuniform heating by the other heating methods, and has the characteristics of fast temperature rise, energy conservation, uniform temperature, environmental protection, safety, and the like.
Description
Technical field
The present invention relates to a kind of processing method that is mainly used in the warm-up mill of papermaking, printing, printing, duplicating, weaving, rubber, plastics, chemical fibre industry, relate in particular to a kind of processing method of the ceramic material warm-up mill that generates heat.
Background technology
The employing warm-up mill heats product and processes, be the means of generally taking in papermaking, printing, printing, duplicating, weaving, rubber, plastics, chemical fibre industry at present, particularly for the product of thin slice reel class dry, technology such as orientation, lamination, embossing, embossing, film are extruded, be more suitable for the application of heat roller and institute's product processed is heated and process.
The mode of heating of the warm-up mill that uses has Steam Heating, the liquid heating of profit, eddy-current heating and several modes of electrical heating at present.Wherein, Steam Heating is by boiler superheated steam to be sent in the warm-up mill, and warm-up mill is heated, this mode of heating needs pressure vessel, there is the carrier pipe line length, the problems such as periodic inspection of leakage and corrosion and pressure vessel take place easily, fewer and fewerily adopted by people.The oil heating then need be at the other oil station that a generation deep fat is set of equipment, by oil pump deep fat is pumped in the warm-up mill, warm-up mill is heated, though this mode of heating effect is better, but exist the oil pump noise big, energy consumption is big, and problem such as leakage takes place easily, also can throw into question to technological operation person's health; Electrical heating divides electrothermal tube directly heating and electromagnetic induction heating dual mode.Electrothermal tube directly heating is that electrothermal tube is directly inserted in the warm-up mill, generates heat to heating roller by electrothermal tube; Electromagnetic induction heating then is to utilize the principle of electromagnetic induction heating that warm-up mill is heated.Because electrical heating has totally, noise is little, the efficient advantages of higher, is subjected to increasing employing, becomes the mode that the heating of warm-up mill is mainly adopted.But the matter of utmost importance that exists in this mode of heating electrothermal tube that to be exactly needs extra and induction auxiliary equipment, cost is higher, and the roller surface heating-up temperature is wayward evenly influences product quality, is difficult to meet the demands for the very high product of ask for something.Second problem is that temperature checking method and test point are difficult to select, and causes temperature control precision low, also influences the quality of product.Therefore necessary this is improved.
Summary of the invention
The objective of the invention is at the existing problem of existing warm-up mill mode of heating, it is very easy to propose a kind of mode of heating, the processing method of homogeneous heating, energy-conservation ceramic coating electric heating roller.
Technical scheme of the present invention is to process according to the following steps:
1), system roller nuclear; Select steel, stainless steel, brass, aluminium, glass or the processing of fiberglass synthetic material in a tubular form, it is 6.3～3.2 that outer surface adopts blasting craft to be machined to roughness Ra;
2), coated with insulating ceramic layer; After roller nuclear cleaning cleaning, clamping adopts plasma spray apparatus on rotary disk, particle diameter 20～40 μ m, purity are at least 98% Al
