The Study In Detection Of Raw Cement By Direct Current D-D Neutron Induced

In the cement production process, the control crude material ingredient reasonable and isstable is the main essential link. The weight crude material quality standard is 3 rate values:Lime saturation coefficient KH, silicic acid rate n, iron rate p. Accurately surveys these ratevalues, to produces the high grade cement to have the vital significance. Until now, the peopleused conventional chemistry sampling analysis method to obtain these 3 rate values. But thechemical analysis method speed is slow, cannot promptly instruct the production. But nucleartechnology method, because it has the radiation penetrability, may provide one new method torealize the cement at the right moment the analysis. The neutron induced instantaneousgamma beam analytic method (NIPGA) may fast carry on the cement crude material analysis.The quick thermal neutron shines to the cement sample in has [ n, γ] Responded, producesthe instantaneous gamma beta spectrum through the analysis, may obtain in the cement eachkind of oxide compound content, thus calculates the cement lime saturation coefficient KH,silicic acid rate n, iron rate p. The pulse neutron generator has fast opens -closes the ability,enhanced the survey signal to noise ratio greatly, therefore it suits this method extremely. Thisarticle introduced has the induced instantaneous gamma beam using the pulse neutrongenerator which quick, the thermal neutron and the cement function produces, to cement limesaturation coefficient KH, silicic acid rate n, iron rate p carries on the survey, obtains theeffective measuring technique and the suitable metering equipment.
