And albite feldspar (microcline or orthoclase feldspar) is an important part of the feldspar in the ore. They usually contain about 3% to 5% Na2O and K2O. Although the crystal structure and physicochemical properties of albite and K-feldspar are very similar, it seems that the still angle of flotation is the only feasible way to separate them. In this study, using dynamic potential measurement, mineral solubility determination, surface tension measurement, adsorption measurement and flotation test, the effective separation range of albite and potassium feldspar amine flotation was investigated under the action of monovalent salt. The results show that NaCl and KCl have the best flotation separation effect of albite and potassium feldspar at a certain concentration. The mechanism of selective flotation separation of potassium feldspar and albite is the same ion (ie added salt). The medium ions are the same as the mineral lattice ions. The adsorption and exchange of different kinds of ions (ie, the ions in the added salts are different from the mineral lattice ions).
Chlorinated polyethylene is a saturated polymer material with a white powder appearance. It is non-toxic and tasteless. It has excellent weather resistance, ozone resistance, chemical resistance and aging resistance. It has good oil resistance, flame retardancy and coloring properties. It is an excellent impact modifier for PVC plastics and a synthetic rubber with good comprehensive performance. It has a very wide range of applications and has been widely used in cables, wires, hoses, tapes, rubber and plastic products, sealing materials, flame retardant transport belt , Waterproof coiled material, film and various profiles and other products.
As a PVC impact modifier, CPE135A has many advantages such as low price, excellent performance, and excellent aging resistance, but it has certain disadvantages in the use of high impact and high hardness products and low temperature resistant products CPE135A. For example, in the formulation of rigid PVC, a large amount of CPE will reduce the hardness and rigidity, which reduces the physical properties of the product; in addition, when the low temperature resistance requirement of PVC products exceeds minus 30°C, CPE135A cannot meet the requirements. Under normal circumstances, modified CPE, such as ACM, RGC135A, etc., can be selected for rigidity and hardness improvement; for low-temperature resistance modification, impact-resistant ACR or other impact modifiers with lower glass transition temperature can be selected.
