Study On Bulking Composite Of The Plant Fiber And Inorganic Matter

The composite regards inorganic matter as the glue and congeals materials , compound with plant fiber, at the same time through is it foam pharmaceutical (aluminum powder ) bulk to the thick liquid material out to add, there can be certain intensity and light quality composite with smaller proportion to get one. This kind of composite regards plant fiber (wooden fiber) as the reinforced-fiber, namely disperse the looks; With the inorganic matter separately -cement and lime, as the matrix ( continuous looks), compounded in the form of pouring. Foam pharmaceutical aluminum powder produces the gas under sure terms , some gas is deposited and stayed in thick liquid material in the form of bubble among them, thus a large number of holes of composite, there is good sound absorption performance while reducing proportion like this. This thesis is focused on correctly the impact on main performance of material of consumption of raw materials carries on test analysis.First of all, the inorganic matter adopted is to rely mainly on lime, there is relatively little cement amount. Select four factors definitely as: the ratio of fiber and the lime,the ratio of aluminum powder and the lime, the ratio of the wooden sulfonic calcium and the lime, and the ratio of the cement and the lime. The consumption of the fiber has certain significance to its density and compression strength in four factors, the influence of other factors is not remarkable. The density of receiving material is in 1000g/cm3, intensity , 2 MPa, equal to intensity with angry concrete. Sound absorption performance is superior to the sound absorption performance of several kinds of timber .Whether in to regard cement as glue congeal complex of material , choose factor: the ratio of fiber and urea formaldehyde A , the ratio of fiber and the cement B, the ratio of aluminum powder and the cement C, 12 alkyl benzene sulfonic and the cement D. Hand in the test in impact on density , compression strength and sound absorption coefficient, and carry on variance and regression analysis. The result of the test shows , the power order of the impact on density and compression strength of the factor is unanimous: B>D>C>A. And when density is heavy,intensity is low. The regression equation received is:Regression equation of the density: M =1.426+0.767a-4.236b +0.005875c +7.663dcompression strength regression equation: N =0.659+3.983a-7.41b +1.25c +72.60d, through comparing with analysing that fetches the best matching, carry on the stability experiment, state the dependability of the conclusion further.
