Results 11–20 of 64 for prirodne smole

carbon fibre → ugljično vlakno

Carbon fibres are threadlike strands of pure carbon that are strong and flexible. Carbon fibres can be bound in a plastic resin matrix to form a strong composite. It is light-weight and stronger than steel.

carbonization → karbonizacija

Carbonization begins when you heat organic substances like wood, sugar or meat with no presence of air; they go black because of secreted carbon.

carotenoids → karotenoidi

Carotenoids are a group of natural pigments in plants responsible for yellow and orange colours, meltable in fats.

cation exchange → kationski izmjenjivač

Cation exchange is a cationic resin has positive ions built into its structure and therefore exchanges negative ions. In the cation exchange, the side groups are ionised acidic groups, such as (-SO₃H, -COOH, -OH) to which cations H⁺ are attached. The exchange reaction is one in which different cations in the solution displace the H⁺ from the solid.

dye → bojilo

Dyes are substances used to impart colour to textiles, leather, paper, etc. Compounds used for dyeing are generally organic compounds containing conjugated double bonds. In practice dyes are classified according to the way in which the dye is applied or is held on the substrate.

elastomer → elastomer

Elastomer is a natural or synthetic rubber or rubberoid material, which has the ability to undergo deformation under the influence of a force and regain its original shape once the force has been removed.

environment protection → zaštita okoliša

From Environment protection law of the Republic of Croatia: By protection of the environment, the following is ensured: complete preservation of environment quality, natural community preservation, rational usage of natural resources and energy in the most favourable way concerning the environment as a basic condition of healthy and sustainable development.

cement → cement

Cement is any various substances used for bonding or setting to a hard material. Portland cement is a mixture of calcium silicates and aluminates made by heating limestone (CaCO₃) with clay (containing aluminosilicates) in a kiln. The product is ground to a fine powder. When mixed with water it settles in a few hours and then hardens over a longer period of time due to the formation of hydrated aluminates and silicates.

cerium → cerij

Cerium was discovered by Martin Heinrich Klaproth (Germany) and by Jöns Jacob Berzelius (Sweden) in 1803 and Wilhelm von Hisinger (Germany) in 1814. Named after the asteroid Ceres this discovered two years before the element. It is malleable, ductile, iron-grey metal. Tarnishes in air; reacts easily with water. Dissolves in acids; ignites when heated. Metal ignites and burns readily. Strong reductant. Cerium is most abundant rare earth metal. Found in many minerals like monazite sand [Ce(PO₄)]. Its oxides are used in the optics and glass-making industries. Its salts are used in the photography and textile industry. Used in high-intensity carbon lamps and as alloying agents in special metals.

coenzyme q → koenzim q

Coenzyme Q (CoQ) or ubiquinone is any of a group of related quinone-derived compounds that serve as electron carriers in the electron transport chain reactions of cellular respiration. There are some differences in the length of the isoprene unit (in bracket on left) side chain in various species. All the natural forms of CoQ are insoluble in water, but soluble in membrane lipids.
