Fireproof fiber falls in different ambient conditions, fall in high temperature circumstance especially, the physical character that has to itself and the chemical reaction to the environment have change, want to had used their good character in using fireproof fiber, prevent adverse ingredient.
1, chemistry and erode
1) chemistry is eroded
Have a few kinds of chemical material that erode action to include to fireproof fiber: Heavy metal of etc of fluorine, fluoride, vanadium, phosphoric acid, alkali.
2) of the dust inside furnace erode
Fireproof fiber is a kind of stable material on chemical composition, because of its porosity the big, area that compare a list is eroded very easily greatly. Contain alkaline He Fan normally in the furnace of burning heavy oil these two kinds of material, above had introduced. Inside the furnace of steely smelt, contain many oxidation calcium (CaO) , oxidation calcium can produce the compound of low melting point, can eat fireproof fiber and promote its to contract. Material has the metal such as iron, nickel, copper to promote fireproof fiber crystallization to change rate significantly, accelerate fireproof fibrous pulverization.
2, electricity and electrostatic property
Fireproof fiber itself not only it is a very good heat insulating materials, also be a very good dielectric at the same time. Because interstitial rate is great, be controlled characteristicly by air, below high temperature resistor rate is reduced.
3, amortization property
Fireproof fibrous is sound-absorbing the gender is very admirable, if also had used fireproof fiber cotton box of air-blower muffle, sound insulation,make amortization material. Particularly right high frequency sound wave is effective, the eject burner to industrial kiln furnace but effectively bring down noise. Graph 2-11 is the scale that passes through reduced rate of volume of fireproof fiber sound.
4, breathe freely characteristic
Fireproof fiber serves as sealed material, have the function that prevents transgression of heat vital energy. It also can serve as the utility that aerate with it as porous material. Of the sort as a result of fireproof fiber and bulk density different, aerate the limits selection of rate is very wide.
5, condensability can
Fireproof fibrous is constrictive and recover from an illness the gender is very admirable, use this one character, can make up the amortize slop that place of furnace kiln key uses, also can use method of vacuum-packed type construction.
6, but function of pliable but strong (heatproof shake sex)
Fireproof fiber base composite material relatively the brittleness quality that the earth improved data of original pottery and porcelain, increased its tenacity and thermal stability. Fireproof fiber serves as be in dispersedly the bases of radical of pottery and porcelain, its performance characteristics that ruptures to will affect composite material directly with differentiation. Fireproof fiber (alumina fiber) as add wild phase or call strengthen put oneself in another's position, improve and raise metallic radical and pottery and porcelain base composite material function.
Zhengzhou flourish fills factitive Central Plains to be able to bear or endure material character, pay attention to the amplification of oneself dimensions not only, more important is to stand in long-term development point of view from beginning to end, ceaseless development gives new-style fireproof data, satisfy more firm market demand ceaselessly thereby, comply with the development of tendency of the day. Major of flourish Cheng Naicai produces all sorts of tall aluminous bricks, firebrick, argillaceous brick, pouring the product such as makings, welcome broad client to come to a factory make an on-the-spot investigation on the spot, establish long cooperative relationship.
