Description Marble Chips are metamorphic rocks formed by the alteration of limestone by heat and pressure. In its pure form, marble is a white stone with a crystalline and sugary appearance, consisting of calcium carbonate CaCO3. Usually, marble contains other minerals, including quartz, graphite, pyrite, and iron oxides. It is used for its chemical properties in pharmaceuticals and agriculture. It is used for its optical properties in cosmetics, paint, and paper. They are used as Industrial Raw Materials with other industrial raw material products such as Silica Flour, Limestone, Aggregate, Quicklime, Talc, Volcanic Rock and Abrasives. Marble is usually a light-colored rock. It is one of the most effective acid-neutralization materials. Being composed of calcite, marble has a hardness of three on the Mohs hardness scale. As a result, marble is easy to carve, and that makes it useful for producing sculptures and ornamental objects. After being sanded with progressively finer abrasives, marble can be polished to a high luster. This allows attractive pieces of marble to be cut, polished, and used as floor tiles, architectural panels, facing stone, window sills, stair treads, columns, and many other pieces of decorative stone. Marble chips work best when used in paths and patios as a substitute for gravel. Although gravel often is used as inorganic mulch around plants, marble chip mulch's reflected sunlight can be too intense for plants in full-sun locations. Today, marble is quarried all around the world and is used to create giant monuments, it is used in building, even down to applications as simple as kitchen counter tops. Itâ??s classified as a metamorphic stone, which means that it has changed composition over time from one type of rock to another.

Description Marble Powder Calcium Carbonate is considered the second purest source of calcium carbonate in nature, where the percentage of calcium carbonate reaches 97% CaCo3. After the stage of mining and extracting raw marble from our quarries in the Kingdom, it is crushed in our crushers to get marble chips. Then sorting it from impurities, sifting it, and grinding it to get marble powder called calcium carbonate. It is used in many industries after being sifted and classified in our factories. It can also be used to equalize the pH to reach PH7 in water treatment projects. It contains more than 19.5% of magnesium oxide and more than 29% of calcium oxide. It is less than 0.3% of silicon oxide, less than 0.7% of alumina oxide, and less than 0.1% of iron oxide, (or less than 0.03-0.04% of iron oxide for unpainted glass). Dolomite marble powder is added in sizes from 100-250 microns. In the coating industry (paints), marble powder calcium carbonate is an essential material, as it forms from 30 - 40% of the paint components and is preferred over calcium carbonate powder due to its crystalline nature. The powder is included in the process of manufacturing paint as a filler to improve some of the paint's natural properties such as thermal resistance, thermal conductivity, density, controlling viscosity, preventing flow, reducing oil absorption, and increasing hardness, by combining it with particles of colored or adhesive materials to form a cohesive and stable material with a high flow. The granular size of the powder should not exceed 20 microns. Some of the paints used in exterior wall cladding require marble powder in sizes 0.3 to 1.2 mm. In the plastics industry, marble powder is used as a basic material in the manufacture of many plastic products such as water and drainage pipes, electrical cables, some parts of electrical equipment, some auto parts, children toys, plastic bags, tableware food preservatives and dishes, decorations, and others. It improves the physical properties of the plastic product, it makes it resistant to deformation as it increases its hardness and resistance by increasing the modulus of elasticity. It reduces the thermal expansion coefficient, makes it have a good external appearance and soft touch, and keeps it from sloughing. In addition, it makes it easy to form by increasing its fluidity and dispersion and reducing production costs.
Sand blasting sand Materials which can be Sandblasted: Sandblasting Process Glass Stone Metals Wood Plastics Steel Brass Aluminum Silver Materials Required for Sandblasting Process: Abrasive Media grit size 80 grit around 0.007 Sand Produces free silica: cause of silicosis, a lung disease Aluminum OxideLasts 30-40 X over sand. Silicon Carbide Lasts at least 40-50X over sand. Garnet Glass Beads Black Magic Walnut Shells Plastic Pellets Description Sandblasting is also known as abrasive blasting. Basically, it is the operation of forcibly propelling a stream of abrasive material against a surface. The sandblasting operation is done under high pressure to smooth a rough surface, roughen a smooth/Shape the surface to remove its contaminants. There are several variants of sandblasting process like bead blasting, Soda blasting and shot blasting. Before sandblasting, it is mandatory to know about its materials and the pros and cons. If your job profile is related to sandblasting or you owned a company that involved in the same process, you need to stay with us. In this article, we will discuss sand blasting machines materials and its pros and corns. But before it, let me also clear some of the details of its operation. There are Two Types of Sandblasting Processes: Water-Driven It is applied for reducing surface deterioration, most commonly water driven process is used for brick or concrete surfaces preparation. Air-Driven This process is best suited for metal surfaces, to prevent moisture buildup and avoid water intrusion in the surface. Sandblasting is the process of propelling abrasive by using the pressurized liquid or compressed gas as propellant. There are many generic terms for this process that is generally related to the sandblasting abrasive media used for this process. Here are the details of abrasive materials.
