The —NCO content is 10% in the prepolymer, the calcium carbonate and petroleum resin content is 15% and 30%, use MOCA/N-330 (function group) is 0.75/0.25 as the mixed curing agent, prepared the normal room temperature cure oily two component polyurethane waterproof coating.
The phase transformation of Cu-Ni-Si alloy was reflected by its change of electric conductivity during aging, so,through which the dynamic equation of the alloy's phase transformation can be gained and, furthermore,on the basis of which two component equation of electric conductivity can be also attained.
Cu Ni Si合金在时效过程中的导电率变化反映了合金中时效析出相的相变过程,因而通过测量时效过程中导电率的变化就可反映该合金时效析出转变的相变动力学方程,在此基础上,还可进一步求得时效时间和温度两个参数下的二元导电率方程。
According to the demands for analyzing two component successive decay curve with constraints in parameter region,a nonlinear programmingdirect search method FLEXIPLEX was adopted to solve optimization object function.
CONCLUSION This study provided a simple and reliable assay which can be used to simultaneously determine two component concentrations of complex chlorzoxazone tablets in human serum and to reseach their pharmacokinetics and bioavailability.
This paper introduces the synthetical method and properties of the two component polyurethane adhesive for lamination, describes the application to dry lamination and finally discusses the influence of some principal factors on the coextruded film quality.
The results show that Ag+ and Cu~(2+)、Zn~(2+)、TiO_(2)have coordinate antibacterial effect. Compaed with to the samples of single component, the samples of two component antibacterial rectorite have lower cost, good stability and highter antibacterial power.
By mixing the rectorite powder carrying Ag+ and rectorite powder carrying Cu~(2+)、Zn~(2+)、TiO_(2 )in different ratio, samples of two component antibacterial rectorite powder are obtained. The coordinate antibacterial effect of these samples are studied.
