2.2. FTIR. The FTIR spectra in Figure 1 shows the typical bands of kaolinite. In the region between 3700 and 3600 cm −1, the stretching frequency of OH bands showed four stretching bands at 3620, 3653, 3670, 3695 cm −1 [28,29,30,31,32].The peaks at 3435 cm −1 in the Wenchang kaolin and 3443 cm −1 in the Maoming kaolin signify the …
As kaolin binds to polymers during processing, it naturally enhances mechanical properties, including strength, impact and flexibility. Kaolin gives plastics and rubbers desirable properties, like better resistance to tears and abrasions. It also improves these products' tensile strength and prevents warping.
Zirkon sangat tahan terhadap perubahan kimia dan abrasi. Ketika unit batuan yang mengandung zirkon mengalami pelapukan dan sedimennya terkikis, sejumlah besar kristal zirkon kecil tersebar. Ini dapat bertahan di tanah, sedimen, dan batuan sedimen selama jutaan - bahkan milyaran - tahun. Mereka dapat bertahan dalam beberapa siklus …
