| With the development of the steel industry,steel production as the main by product steel slag production also increased rapidly.In recent years,domestic steel slag emissions of about 19 million tons,while the effective utilization rate is very low.Steel slag as a waste,not only will take up a lot of land,but also pollute the environment.Because the types of steel slag,coupled with complex processing technology,involving a wide range,so the treatment and use has not been the actual development and development.The effective use of steel slag and its secondary resources has become a hot research at home and abroad.How to use the existing steel slag as a resource,the development of high value-added products,has become China's economic sustainable development of the event.This topic is based on fuzzy cluster theory in the study of steel slag base study on properties of rubber,Includes:collection of steel and rubber research information,check out the fuzzy cluster methods of literature and learning to use a statistical software SPSS and Origin,Applying fuzzy cluster theory Origin and methods using SPSS software to analyze the results,Clearly after joining of steel slag,properties of natural rubber and styrene-butadiene rubber under different curing conditions change.The following conclusions can be drawn:?1?the larger the r1/r2 of the natural rubber of 20 min,the better the tensile performance.In 1400,the greater the r1/r2,the worse the tensile performance;The larger the r1/r2 of natural rubber,the better the tensile performance.The greater the r1/r2 of natural rubber,the worse the tensile performance.The variation of tensile strength of natural rubber was the same as that of r1/r2.The change of tensile strength of 45min styrene butadiene rubber was opposite to that of r1/r2.The change of elongation of45min styrene butadiene rubber was opposite to that of r1/r2.?2?the larger the r1/r2 of natural rubber is,the larger the elongation is.The greater the r1/r2 of the natural rubber,the smaller the elongation rate,and the larger the r1/r2 in1400,the larger the elongation.The greater the r1/r2 of natural rubber,the greater the elongation.The change of elongation of 45min styrene butadiene rubber was opposite to that of r1/r2.?3?changes of 300%fixed strength of rubber material with different particle size of iron water desulfurization slag:the greater the r1/r2 of natural rubber of 20 min vulcanization,the greater the stretching intensity of 300%;The greater the r1/r2 of the natural rubber,the greater the 300%fixed elongation intensity;The greater the r1/r2 of the natural rubber,the greater the strength of 300%.?4?under different Numbers of natural rubber for 20 min vulcanization,the greater the r1/r2,the greater the hardness;The greater the r1/r2 of natural rubber,the greater the hardness;The greater the r1/r2 of natural rubber,the greater the hardness;In the case of600 eyes,the hardness remains the same,with no relation to r1/r2.In 1000 eyes,in 1400,r1/r2 is bigger and harder.?5?the tear change of natural rubber for 20 min was not related to the change of r1/r2,but the larger the number,the smaller the tear strength.The tear change of natural rubber is not related to the change of r1/r2,but with the same number and size,the larger the number,the larger the tear strength.The r1/r2 change is the same as that of r1/r2.The larger the r1/r2,the greater the tear strength.The change of r1/r2 was the same as that of r1/r2.The change of abrasion consumption of 45min butadiene rubber was opposite to that of r1/r2.?6?the iron water desulfurization slag powder with a fineness of 600-1000 is of certain reinforcement and improved wear resistance;The processing properties of the adhesive were improved and the flame retardant properties were improved.The wear-resisting property of adding iron water desulfurization slag covering rubber is excellent. |
