Papermaking is a complex process in which paper is produced from pulp (wood), water, filler, and chemicals. The goal in papermaking is to produce paper having the specified quality while minimizing the costs. The process consists of several subprocesses in which raw materials are prepared, mixed and diluted with water, the paper web is formed and
papermaking, formation of a matted or felted sheet, usually of cellulose fibres, from water suspension on a wire screen. Paper is the basic material used for written communication and the dissemination of information. In
Publisher Summary. The papermaking process consists of several major steps: stock preparation, sheet forming, pressing, drying, and surface finishing. Starch is an important component of many paper grades. Starch consumption by weight in papermaking and paper conversion processes ranks third after cellulose fiber and mineral pigments.

All About 7075 Aluminum (Properties, Strength and Uses)
2 · Physical Properties of 7075 Aluminum. 7075 aluminum is composed of 90.0% Al, 5.6% Zn, 2.5%Mg, 0.23%Cr, and 1.6% Cu, though these numbers nominally fluctuate depending upon manufacturing factors. Its density is 2.81 g/cm3 (0.102 lb/in³), which is relatively light for a metal. 7075 aluminum alloy is one of the strongest aluminum alloys
