Control Diesel engine form pollution diesel particulate collector generally comprise: shell, collect the fragility particulate filter of the particle in diesel emissions or collector and mounting mat, between the outer surface that mounting mat is configured in filter or collector and the inner surface of shell, thus fragility filter or collector structure are flexiblely contained in shell.
Fragility catalyst support structures generally comprises the overall structure be made up of crisp metal material or brittle ceramic materials (such as aluminium oxide, silica, magnesia, zirconia, cordierite, carborundum etc.).These materials provide the framework structure type with many gas channels.These overall structures are highly brittle, even if to such an extent as to small vibration loads or stressed being usually enough to makes it break or fragmentation.Avoid the thermal shock pointed out and mechanical shock and other pressure in order to protect friable structure above, and in order to provide heat insulation and sealing gland, within the gap between friable structure and shell, configure mounting mat.
The mounting mat material used should be able to meet any amount of design or desired physical considerations that friable structure manufacturer or emission-control equipment manufacturer list.Such as, mounting mat material should be able to produce effective residual maintenance pressure to friable structure, even if when emission-control equipment stands the temperature fluctuation of wide region time, this situation causes metal-back to occur significantly expanding and shrinking relative to friable structure, within certain period, also cause the remarkable compression to mounting mat and relaxation cycle.
The pottery used in emission-control equipment and metal matrix (substrates) are arranged within the metal-back with inorfil base mounting mat the most usually.This mounting mat material can only containing inorfil.But mounting mat material also can containing the fiber of other type, organic bond, inorganic bond and expanding material.
Mounting mat must play and effectively keep carrier effect in position under wide-range operating temperature conditions.Due to vibration, matrix (substrate) is subject to the axial force acting on matrix.Because metal-back to have the fact of the different expansion of degree than matrix itself, mounting mat also plays the effect compensating this expansion.Various emission-control equipment operates to the temperature range of about 1200 DEG C the environmental condition of about 20 DEG C.Therefore, mounting mat must provide firm maintenance pressure functional in the temperature range of this wide region.
The non-expansibility mounting mat that some is purchased typically uses the non-of high diameter can respirable fibres (non-respirablefibers), to conform to adjustment.But, only comprise that high diameter is non-the mounting mat of respirable fibres can have undesirable high thermal conductivity.
The biosoluble inorganic fibers be purchased has relatively little diameter, and it demonstrates relatively low thermal conductivity.
It is desirable that for the mounting mat of emission-control equipment, require that it can use under High Operating Temperature, and demonstrate low heat conductivity in industry.
