Preparation and Mechanical Properties of Polypropylene

Polypropylene (PP)−clay hybrids (PPCH) have been prepared by simple melt-mixing of three components, i.e., PP, maleic anhydride modified polypropylene oligomers (PP-MA), and clays intercalated with stearylammonium. The dispersibility of 10--thick silicate layers of the clays in the hybrids was investigated by using a transmission electron microscope and X-ray diffractometer. It is Get price

However, because CaCl 2 is a nonsymmetrical electrolyte (Ca and Cl possess different valencies), 1 mol L -1 CaCl2 would give 1 mol L -1 Ca, 2 eq L -1 Ca and 2 mol L-1 Cl, or 2 eq L-1 Cl. It follows that if one needs to convert moles per liter to grams per liter, one needs to multiply the moles per liter with the molecular weight of the salt or Get price

Similarly, acid leaching of natural and heated vermiculite samples at 20C resulted only small changes in the X-ray diffraction patterns and infrared spectra, but with the increase of leaching temperature to 90C, significant changes, i.e. the dissolution of vermiculite structures and the formation of hydrous amorphous silica phase, were observed.

Biosorption : Techniques and Mechanisms

Clay materials possess a layered structure and are considered as host materials. They are classified by the differences in their layered structures. There are several classes of clays such as smectites (montmorillonite, saponite), mica (illite), kaolinite, serpentine, pylophyllite (talc), vermiculite and sepiolite (Shichi and Takagi, 2000).
