Abstract
The invention provides a far infrared coating for a far infrared heater. The coating is prepared by mixing and stirring the following components in percentage by weight: 40 to 50 percent of chromium oxide, 20 to 30 percent of iron oxide red, 10 to 20 percent of sodium silicate and the balance of quartz sand. When the coating is used, the coating is sprayed on the application surface by a conventional spraying method, and the coating is vitrified by high-temperature baking after spraying, so that the coating enters the pores of the inner wall of the heater to form a radiation layer; the radiation layer formed by the coating has high efficiency of thermal radiation, and other chemical additives are not needed, so the coating has low cost and is environment-friendly and energy-saving; the coating has good adhesion; and during use, the coating can play a role in fixing the heating material inside the heater.
Description
Technical field
The present invention relates to a kind of coating, particularly a kind of far ultrared paint that is used for far infrared heater belongs to the technical field of coating.
Background technology
Far ultrared paint is the high-temperature coatings that generally uses on the present far infrared heater.Far ultrared paint of the prior art has: the ET-4 of Britain, the C-10A of the U.S., G-25, the CRC1000 of Japan, CRC1500 etc.They all are to be raw material with the oxidized metal, are aided with minor amounts of additives again, and are formulated through calcination.
Recently, disclose relevant coating in the Chinese patent literature, patent application CN1552779A discloses a kind of high temperature far ultrared paint, and this coating mainly consists of zirconium white, chromic oxide, ferric oxide, carborundum, clay, wilkinite, titanium dioxide, brown corundum; Patent application CN1631209A discloses a kind of far ultrared paint efficiently, and its main component is zirconium white, ferric oxide, silicon oxide, manganese oxide, Suzhou soil etc.; Patent CN1493626A discloses the far ultrared paint of a kind of SiC of containing, and its main component is carborundum, ferric oxide, cobalt oxide, manganese oxide, aluminum oxide, chromic oxide, nickel oxide etc.Patent application CN1044255C discloses a kind of coating of tobacco-roasting chamber, and its main component is carborundum and ferric oxide, and above-mentioned relevant far ultrared paint all is to be raw material with metal oxide or carborundum, and therefore, its cost is higher; And the emittance instability, particularly in the high-temperature zone, the emittance of coating is unstable especially.
Summary of the invention
The objective of the invention is to, the far ultrared paint that is used for far infrared heater of a kind of radiation efficiency height, with low cost and energy-saving and environmental protection is provided.
In order to solve the problems of the technologies described above, a kind of far ultrared paint that is used for far infrared heater of the present invention, wherein, mix together by chromic oxide, iron oxide red, sodium silicate and quartz sand, by weight percentage: chromic oxide is that 40%-50%, iron oxide red are that 20%-30%, sodium silicate are 10%-20%, and surplus is a quartz sand.
Above-mentioned a kind of far ultrared paint that is used for far infrared heater wherein, by weight percentage, is mixed together by chromic oxide 45%, iron oxide red 25%, sodium silicate 15% and surplus quartz sand.
When the present invention uses, the spraying method by routine with paint spay-coating in application surface, after the spraying through high bake, porcelainization can take place in coating, coating is entered in the pore of well heater inwall, form radiating layer, the thermal-radiating efficient height of radiating layer that this coating forms, and need not to add other chemical additives, therefore, the lower and environmental protection, energy-conservation of cost, and the cementability of this coating is better, during use, can play fixed action to well heater inside heating material.
Embodiment
The invention will be further described below in conjunction with embodiment.
Iron oxide red has another name called ferric oxide, calls magnetic oxygenated; The high permeability ferric oxide; Burn limonite; Burn reddish brown on; Colcother; Iron powder, rouge and powder; Venetian red (main component is a ferric oxide), ferric oxide.
Sodium silicate is being commonly called as of water glass, has another name called water glass (xNa2O.YSiO2), colourless, dark green or brown solid or thick liquid.Water glass is that cooling is pulverized and made by the congruent melting in the fusing kiln of silica (quartz sand), soda ash (or native alkali), and its fuel is that matchmaker, Sweet natural gas, coal gas all can.Sodium silicate production process can be divided into two kinds of dry method and wet methods, and employed usually is dry production solid bubble flower alkali, becomes the fluid bubble flower alkali of required specification again through dissolution transitions, and its turnover ratio is 1: 2.5.The raw material of producing bubble flower alkali is quartz sand, soda ash, the two is mixed by a certain percentage deliver in the reflecting kiln, and packing is solid bubble flower alkali after the shrend of high-temperature calcination melting furnace.Solid bubble flower alkali helps transportation, stores.Solid bubble flower alkali is dissolved into liquid with it be fluid bubble flower alkali under certain temperature, pressure.
Quartz sand is a kind of nonmetallic mineral, is a kind of silicate minerals of hard, wear-resisting, stable chemical performance, and its essential mineral composition is SiO2.
In order to solve the problems of the technologies described above, a kind of far ultrared paint that is used for far infrared heater of the present invention, mix together by chromic oxide, iron oxide red, sodium silicate and quartz sand, by weight percentage: chromic oxide is that 40%-50%, iron oxide red are that 20%-30%, sodium silicate are 10%-20%, and surplus is a quartz sand.The thermal-radiating efficient height of coating of the present invention, and need not to add other chemical additives, therefore, the lower and environmental protection, energy-conservation of cost.
