Ronghua Refractory Technology Co., Ltd. focuses on the research and development and manufacturing of refractory materials and has cooperated with many high-temperature companies around the world for many years.
React according to domestic GDP numerical value, in last few years of GDP raise the development that cannot leave industry ceaselessly, the generation of new-style and fireproof material laid a foundation for the development of our country industry, also rose to assist at the same time, the action of stimulative improvement.
Alumina is hollow the ball is industrial alumina blow what make and become through tall Wen Dianrong. Its advocate A-AL203 of crystallization Xiang Wei, chemical composition is more than for AL203 98.5% , sio2 and Fe203 are less than respectively 0.5% . Hollow ball grain is the glomeration of white, hollow, Bao Bi, natural grading is 5-3mm7%-10% commonly, 3-2mm10%-17% , 2-1...
Firebrick of alumina heat insolation can use as the working layer that contacts blaze directly or use as thermal insulation. Porcelain of wide application Yu Tao, fireproof material is firing component of sintering furnace of kiln, pulverous metallurgy, semiconductor is firing kiln and the kiln stove that have nitrogen and reductive nitrogen.
Tall aluminous qualitative adiabatic firebrick can use as the working layer that contacts blaze directly or use as thermal insulation. Wide application and pottery and porcelain, fireproof material is firing original of sintering furnace of kiln, pulverous metallurgy, semiconductor is firing kiln and have hydric the kiln furnace with reducing atmosphere.
What is Molaishi 1924 British Bao article (L of · of Bowen · N) a kind when discover composition is 3Al203 · 2Si02 new mineral. Subsequently, the Mo Er that is in England (Mull) discover this is planted on the island mineral. Bao Wen plants this mineral name for Molaishi. Mo Laishi pledges fireproof material divides agglomeration Mo Laishi and electric frit Mo Laishi brick two kinds. With...
Silicon calcareous plate is it is main raw material with diatomite and lime, add the adiabatic and fireproof product that enhances fiber to be made. Silicon calcareous plate weighs siliceous calcareous plate again. Silicon acid board can curium but Zuo , can make board, piece or the appearance such as bushing, can use the insulation material that makes the heating power conduit such as electric power, chemical industry, metallurgy, shipping and industrial kiln oven, and building, ...
Build in build by laying bricks or stones of industrial kiln furnace in the center to reduce heat loss due to radiation of surface of body of heater of estrangement of caustic of accumulation of heat, of kiln furnace outer all use light qualitative firebrick to serve as heat-insulation layer, the density of general light qualitative firebrick small, porosity tall, thermal conductance sex of small, heat preservation is good and the characteristic such as the compression strength with have particular, light qualitative firebrick makes material of construction of body of heater, but...
Mo Laishi pledges adiabatic brick is the adiabatic and fireproof product that makes for main raw material with Molaishi. Brick of Mo Laishi qualitative heat insolation high temperature resistant, intensity tall, thermal conductance is low, can contact blaze directly, apply to liner of all sorts of industrial kiln furnace.
Weight of brick of light qualitative heat preservation is light, porosity tall interior contains tiny stoma, can reduce loss of quantity of heat of body of kiln boiler setting, have capacity of better accumulation of heat at the same time. Because this is among the thermal insulation of industrial kiln furnace,use extensively. Use a kind of firebrick only and any furnace are not become, the mutual collocation that needs a different firebrick is used...
① : ? Enrol of of wholesale of ⒀ of dysentery of of that Ting wholesale to enrol quantity of of that Ting wholesale to enrol of wholesale of flute of ひ of mildew of cowardly of that the larva of a tapeworm or the cercaria of a schistosome Yin of elaborate of Nao busy touchs deficient foolish of bridle of of copy F Di washing with watercolors - Al203, chemical composition is more than for Al203 98.5% , sio2 and Fe203 are less than respectively 0.5% . Hollow ball grain is the glomeration with white, hollow, thin wall. ② : ? Is Qian of Qi of Zhu taken especially?
Tall aluminous qualitative adiabatic brick is the Al203 content that controls for main raw material with aluminous alumina do not be less than the adiabatic and refractory products of 48% its produce craft to use bubble method, also can use light add content way.
Some closer year come, manufacturing technology is in promotion, manufacturing level is rising, the requirement of product quality also is in increasingly gradual, business of fireproof material demand also had higher demand to brick of light qualitative heat preservation, however the brick of light qualitative heat preservation that Cheng Naicai of our Zhengzhou flourish produces has the product quality that makes a client satisfactory and property. Now, home of heat preservation brickyard...
