In the construction of kiln furnace, fireproof material expands seamed stuff stuff is very serious, they are used at absorbing material to expand in the heat below high temperature, prevent lining structure to suffer because of expanding be restricted and produce crackle or damage. It is below a few expand commonly usedly seam stuff stuff:
1.Blanket of fiber of pottery and porcelain: Blanket of fiber of pottery and porcelain is had good high temperature resistant function and thermal stability, commonly used expand at fill seam. Their softness is easy bend, can get used to aperture change well, and can absorb heat effectively expand.
2.Expand pearlite: Expand pearlite is a kind of stuff stuff that pledges gently, have good heat proof quality. It is commonly used at fill bigger expand aperture, can avoid loss of quantity of heat effectively, the heat that absorbs material expands.
3.Paper of tall aluminous fiber: Paper of tall aluminous fiber is what by tall aluminium fiber makes one kind is flexible material, apply to what high temperature environment falls to expand seam fill. It is had tall fireproof spend and low thermal conductivity, can bear the severe exacting condition of furnace of high temperature kiln.
4.Asbestine board (already was replaced gradually) : On the tradition, asbestine board is used extensively at kiln furnace to expand seamed stuff stuff, yinjinai high temperature and good heat proof quality. But because asbestine is right healthy harm, already was replaced by other data place stage by stage.
5.Module of siliceous aluminous fiber: Module of siliceous aluminous fiber is compressed by siliceous aluminous fiber shape make, have good thermal stability and high temperature resistant function, commonly used at furnace of high temperature kiln expand seam fill.
6.Fireproof fiber spacer: Fireproof fiber spacer is made by siliceous aluminium or fiber of tall aluminous oxide normally, have good flexible and high temperature resistant function, can use at fill expands lesserly to seam.
7.Expand vermiculite: Expand vermiculite is a kind natural and mineral, the bulk after be being handled through high temperature expands, have good heat insulation gender and absorb heat to expand ability, commonly used at kiln furnace expand seam fill.
Condition of the specific work temperature of furnace of these material basis kiln, operation and expand seamed size and position undertake choosing, ensure the security that issues lining in high temperature and stability.
