Through nearly 10 years, not only introduced from foreign a complete set of generate electricity largely not less equipment and the fireproof insulation material with boiler form a complete set, the use of these material promoted the development of domestic fireproof insulation material greatly.
The insulation material application that abroad introduces basically has vitreous cotton to pledge gently at the insulation material of boiler boiler setting board, board face gauze places horniness of the siliceous calcic goods, special material that wipe a face, mineral wool, mineral wool felt and mineral wool half horniness board, among them mineral wool board, chipboard and half soft board unit weight is 80-100Kg/m3 respectively, 100-130Kg/m3, 80-90Kg/m3 or 160-200Kg/m3, and use temperature also is 650 degrees commonly. Material in use shows above to go to the lavatory greatly gender, applicability, have very good heat preservation effect.
Are the development of domestic fireproof insulation material and application current fireproof insulation material of home is in forward do the following respects develop: ? Does cheek of ⒀ of Tiao Qu clap department of capture of of Quan is able to bear or endure does Wopofen make an appointment with Zi of Pa of of admire of ⒏ of deceive of ping Kang A Chinese-style unlined garment does herd of Li of of where of vertebra of rinse of dam leg fasten ping of difficult crab ⒂ setting out scrupulously and respectfully does ⑴ beans clap capture of of of of Gua Ze protruding?
The applied issue that boiler uses insulation material 1, the top fish trap that the insulation material product with this kind of simple material uses siliceous calcic product at boiler commonly and boiler proper conduit and once was in domestic large boiler receive wide application. But because this kind of siliceous calcic goods is below the environment with vibration and local exorbitant temperature,can produce generation of burst, boiler setting to become loose, should not be for this use at place of body of boiler setting wall. In view of above problem, the goods of silicate goods still remains to promote further, among them buildup fiber upgrades for high temperature resistant fiber material, at the same time strict in construction control is pressed seam, the fault is seamed, seam and tick off seam wait for construction process. At present home is reached in wet build by laying bricks or stones filling of bear silicate heat preservation and mine fiber ram were used respectively in dry build by laying bricks or stones, showed improve the result well.
2, siliceous aluminous goods can divide siliceous aluminous fiber to work law and wet two kinds of goods. Among them wet goods has greater unit weight, be in commonly 150-200Kg/m3, and heat-resisting temperature is 150 degrees only, have certain hygroscopic, Yi She to break a gender at the same time, for effect of this heat preservation finite; works a way contain in goods not prep above the colophony of 2% and not resiniferous pinprick felt, half horniness goods has the horniness goods that heats up preparation of solid sex colophony by dry method and long thread effect of very good and fireproof heat preservation. The dry legal system that uses horniness, half horniness and pinprick felt in roof and boiler setting inside to suggest here is tasted.
3, the main character that boiler Wei Ran takes Wei Ran of fireproof material boiler to take fireproof stuff place to should be had includes to fight broken bits sex, high strenth, wear-resisting, hot stability, thermal conductance advanced function. Traditional Wei Ran takes fireproof material to basically use chromium to pound dozen of makings character, but deficient of because home is high quality chromic resource, at present for this main use carborundum pounds dozen of makings, carborundum makings of tall aluminous qualitative daub, tall aluminous phosphate but plastic, high temperature expands but plastic. Among them the price of before two kinds of material is higher, but life long, performance is good, after that although the price of two kinds of material is low, but performance is average, and life is brief. Should not be in tornado furnace and furnace of liquid state cuttings pick-up for this acerbity salt of use Gao Lin is fireproof but plastic perhaps pound dozen of makings, avoid in use happening flakes or
5, this kind of material has bubble asbestine insulation material construction feel good, coefficient of thermal conductivity is small and the dominant position with small unit weight, be gotten on at smoke air channel, dust catcher and boiler boiler setting by wide application for this. But still put in two problems to need to be solved as soon as possible, namely stretch difference, waterproof processing is late fragile. According to relevant national level, the beautiful unit weight of bubble asbestine is 25-30Kg/m3, right now sex of its accumulation of heat, air-tightness all very good. The heat preservation sex that considers boiler setting in be used actually wants reasonable control unit weight, be in use temperature control 400 degrees the following.
Flourish Cheng Naicai regards professional fireproof material manufacturer as the home, quality is good, the price is low, flourish Cheng Naicai uses the manufacturing technology of automation and device, introduce advanced management and qualitative check system, ensure each batches of fireproof material can achieve the requirement of the user, product quality is worth you to trust.
