[Infrared spectroscopic studies of the effect of hydrotalcite on the capability of agricultural film].
Different kinds of hydrotalcite and their effects on the optic capability, transmittance, infrared anti-transmittance and heat preservation of agriculture film were studied by IR spectroscopy. It was found that the haze degree of the film decreased about 1.5% because the diameter of the hydrotalcite made in Dalian was bigger than those made in Japan. Compared to the french chalk, the hydrotalcite had much better capability of infrared anti-transmittance. But from the spectra of hydrotalcite, whichever made in Dalian or in Japan, there was no infrared absorption in the region of 1100-1200 cm(-1). Compared with the wavelength of 9-11 microm, the absorbance band at 1360 cm(-1) had a little shift. Hence, the capability of heat preservation of hydrotalcite-added agriculture film would be studied in the future work.
