Dil
Anlamı
İngilizcesi İngilizce
Component of the cell walls of plants, along with cellulose Lignin is largely responsible for the strength and rigidity of plants, but its presence in paper and board is believed to contribute to chemical degradation There can be large amounts of lignin present in pulp made from wood It is not removed in the production of mechanical pulp, but it can be removed almost completely in chemical papermaking processes.
İngilizcesi İngilizce
Lignin is a substance related to cellulose that provides rigidity and together with cellulose forms the woody cell walls of plants and the cementing material between them.
İngilizcesi İngilizce
Component of the cell walls of plants that occurs naturally, along with cellulose Lignin is largely responsible for the strength and rigidity of plants, but its presence in paper is believed to contribute to chemical degradation To a large extent, Lignin can be removed during manufacturing.
İngilizcesi İngilizce
An amorphous polymer related to cellulose that together with cellulose forms the cell walls of woody plants and acts as the bonding agent between cells.
İngilizcesi İngilizce
Component of the cell walls of plants that occurs naturally, along with cellulose Lignin is largely responsible for the strength and rigidity of plants, but its presence in paper and board is believed to contribute to chemical degradation It can be, to a large extent, removed during manufacture No standards exist for the term 'lignin-free' and additional research is needed to determine the precise role of lignin in the durability and permanence of paper.
İngilizcesi İngilizce
The noncarbohydrate portion of the cell wall of plants It is removed from wood fiber during the pulp manufacturing process, leaving cellulose for papermaking Lignin by-products have found important uses as dispersing agents, oil well drilling mud additives and as a commercial source of vanillin.
İngilizcesi İngilizce
Compound contained in the woody cell walls of trees which gives paper a brown color It is usually removed from wood pulp for fine or bleached paper products.
İngilizcesi İngilizce
Complex constituent of the wood that cement the cellulose fibers together.
İngilizcesi İngilizce
Compound that 'glues' cellulose fibers together in trees Lignin adds opacity to papers, but it also reduces brightness and whiteness.
İngilizcesi İngilizce
Substance in trees that holds cellulose fibers together Free sheet has most lignin removed; groundwood paper contains lignin.
İngilizcesi İngilizce
Natural adhesive which binds wood fibres together in the tree and imparts rigidity Pulp brightness depends on the amount of lignin remaining in the pulp.
İngilizcesi İngilizce
Phenolic compounds impregnating and strengthening cell walls Xylem cells and fibers are typically lignified but other cells in the stele or cortex can also be lignified.
İngilizcesi İngilizce
In wood anatomy, as distinguished from cellulose the second most abundant constituent of wood, located principally in the middle lamella, which is the thin, cementing layer between the wood cells.
İngilizcesi İngilizce
Complex woody polymers found in vascular plants.
İngilizcesi İngilizce
Substance characterizing wood cells and differing from cellulose in its conduct with certain chemical reagents.
İngilizcesi İngilizce
Complex polymer; the chief non-carbohydrate constituent of wood; binds to cellulose fibers to harden and strengthen cell walls of plants.
İngilizcesi İngilizce
Component of the cell walls of plants, along with cellulose Lignin is largely responsible for the strength and rigidity of plants, but its presence in paper and board is believed to contribute to chemical degradation There can be large amounts of lignin present in pulp made form wood It is not removed in the production of mechanical pulp, but using chemical processes, it can be optimally removed.
İngilizcesi İngilizce
Hard substance embedded in the cellulose of plant cell walls that provides support.
İngilizcesi İngilizce
Chemically complex substance found in many plants that bonds the cellulose fibers Lignin can be largely removed during pulping, but the cost of low-lignin papers is higher than than that of high-lignin or groundwood papers Lignin is believed to contribute to the degradation of both papers and photographs.
İngilizcesi İngilizce
Organic substances which act as binders for the cellulose fibers in wood and certain plants, and adds strength and stiffness to the cell walls Chemical structure of lignin is composed of a polymer of high carbon content but distinct from the carbonates Consists of C6,C3 units.
İngilizcesi İngilizce
Lignin is a major component of the cell wall of certain plant materials, such as wood, hulls, straws, and over-ripe hays This fraction is essentially indigestible by all animals and is the substance that limits the availability of cellulose carbohydrates in the plant cell wall to rumen bacteria.
İngilizcesi İngilizce
Stiffening substance that is the most abundant polymer in plant cell walls after CELLULOSE.
İngilizcesi İngilizce
An amorphous polymer related to cellulose that cements cell walls, helping them stay rigid Lignin is highly resistant to decomposition.
İngilizcesi İngilizce
Substance in trees that holds cellulose fibres together Free sheet has most lignin removed; groundwood paper contains lignin.
İngilizcesi İngilizce
The organic substance that holds together the individual fibers of wood.
İngilizcesi İngilizce
Hard material is cellulose plant cell walls used for support in terrestrial plants.
