This apparently is the release of carbon dioxide as industrial pollutant, which creates a green house effect which causes the environment to overheat. There are two sides to this issue, each in vigorous disagreement with the other. Unfortunately, environmental concerns take center stage after a fashion.
Additives Clay, fillers, dyes, sizing and other chemicals added to pulp to give the paper greater smoothness, color, fibered appearance or other desirable attributes. A measure of the amount of chlorine that is chemically bound to the soluble organic matter in the effluent.
Aerated Lagoon A biological wastewater treatment method in which air oxygen fed into an aeration basin reduces the effluent load. Against the Grain Cutting, folding or feeding paper at right angles to the grain or machine direction of the paper. Agave An aloe plant sometimes used as a source of long papermaking fibers similar to sisal hemp.
Agglomeration A cluster of particles or fibers. Aging Irreversible alteration, generally deterioration, of the properties of paper in course of time. Aging also causes reduction in brightness and yellowing effect.
Aging Resistance The ability of pulp or paper to maintain certain physical properties, such as strength and brightness, over long periods of time. Sometimes referred to as stability or permanence. Aging Test An evaluation of products and raw materials in the pulp and papermaking process based on an accelerated artificial aging procedure to determine the extent that physical and chemical properties will change with time.
Agitator Equipment used to keep content of a tank or chest in motion and well mixed. Air Brush Coater A coater, which uses the pressurized air to atomize the coating mixture and spray it on the paper.
Air Drying Using Acid paper rain term air to dry pulp or paper sheets.
Air Filter Paper A type of paper used for filtration of air to remove suspended particles. Air Knife Coater A device that applies an excess coating to the paper and then removes the surplus by impinging a flat jet of air upon the fluid coating, leaving a smooth, metered film on the paper. Air Laying or Air Laid Process A nonwoven web forming process that disperses fibers into a fast moving air stream and condenses them onto a moving screen by means of pressure or vacuum.
Air Laid Nonwoven An air laid web that has been bonded by one or more techniques to provide fabric integrity. Air Laid Web A web of fiber produced by the air laid process. Air Laid Pulp An air laid nonwoven that is produced with fluff, wood pulp.
Air Permeability Commonly referred to as " porosity. Typically measure by the Gurley or the Sheffield porosity tests, which measure the volumetric flow of air through the paper thickness. Air Pollution The contamination of air around the plant due to the emission of gases, vapors and particulate material in the atmosphere.
Albumin Paper A coated paper used in photography; the coating is made of albumen egg whites and ammonium chloride. Algae Micro organic plant life that forms in paper mill water supplies. Algicides Chemicals added in to the paper mill water fresh, white, back etc.
Alkali Lignin Lignin obtained by acidification of an alkaline extract of wood. Alkfide Process A variation of the kraft process using hydrosulfide sulfide-type cooking chemical. It was developed for continuous cooking using a two-body digester for a two-stage cook.
Alkali Resistance Freedom of paper from a tendency to become stained or discolored or to undergo a color change when brought in contact with alkaline products such as soap and adhesives.
Alkaline Extraction Alkaline extraction, i. E stage, is used in lignin removal before or between bleaching stages; the stage is often enhanced with an oxidizing agent, oxygen Eo stagehydrogen peroxide Ep stage or both Eop stage.
Paper manufactured under alkaline conditions, using additives, basic fillers like calcium carbonate and neutral size. The anti-aging properties in alkaline paper make it a logical choice for documents where permanence is essential. Alkaline Pulping Pulping by alkaline solutions of sodium hydroxide, with or without sodium sulfide.
Without sodium sulfide it is called soda process and with sodium sulfide it is known as Kraft or sulfate process. Alkenyl Succinic Anhydride ASA ASA is a sizing agent designed to increase resistance to water penetration in the case of paper formed under neutral or alkaline conditions.
ASA is especially used in cases where full cure is desired before the size press and where it is important to maintain a high frictional coefficient in the paper product.
The portion of the pulp or other cellulosic material that will not dissolve in Alpha Pulp A specially processed, high alpha cellulose content, chemical pulp.
It is also called dissolving pulp.GIBBERELLIC ACID KITS and SUPPLIES. Kits and Supplies Gibberellic Acid-3 Information Sheet GA-3 Quick-Start Instructions Is GA-3 Natural and Organic? Acids in solution have a pH below , a sour taste, releases hydroxyl ions in water, and turn litmus paper red.
Acids are divided into two main classes: (1) Strong acids are very corrosive and cause severe skin burns, examples are hydrochloric acid, nitric acid, and sulfuric acid. Also called mineral or inorganic acids. (2) Weak acids are mildly . Acid Rain Research Paper.
By Lauren Bradshaw. April 10, You can also order a custom essay, term paper, research paper, thesis or dissertation on Acid Rain from our professional custom writing service which provides students with high-quality custom written papers.
Hydrochloric acid is a strong corrosive acid that is commonly used as a laboratory reagent. It is formed by dissolving hydrogen chloride in water. Acid soils and alkaline soils See diagram Nitrogen cycle Soil pH is a measure of the acidity of the soil, on a scale from 1 to 14, the pH scale.
A neutral substance such as pure water has a value of 7. Description. Sulfuric acid will exist as particles or droplets in the air if released to the atmosphere. It dissolves when mixed with water. It has moderate acute (short-term) toxicity on aquatic life.
