Bottle Crate
A bottle crate or beverage crate is a container used for transport of beverage containers. In the present day they are usually made of plastic, but before the widespread use of plastic they tended to be made of wood or metal. Beverage crates began to be made of HDPE in the 1950s. Such crates can be long-lasting. In the 1980s in Sweden, a take-back campaign was organized, when 25-bottle crates were replaced by the more ergonomic 20-bottle crates. Some of the crates returned for recycling had been in use since the 1960s. Because manufacturers avoid lead-based and cadmium-based pigmentations, in response to legislation and public opinion, they have had to resort to other methods of colouring HDPE crates. In Japan, since the early 1970s, HDPE bottle crates have been pigmented with a variety of perylene, quinacridone, azo condensation, and Isoindoline pigments. Japanese manufacturers have modified these in order to control nucleating behaviour, and have improved weathering perf ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shipping Container
A shipping container is a container with strength suitable to withstand shipment, storage, and handling. Shipping containers range from large reusable steel boxes used for intermodal shipments to the ubiquitous corrugated box design, corrugated boxes. In the context of international shipping trade, "container" or "shipping container" is virtually synonymous with "#Intermodal freight containers, intermodal freight container" (sometimes informally called a "sea can"), a container designed to be moved from one mode of transport to another without unloading and reloading. Intermodal freight containers Freight containers are a reuse, reusable transport and storage unit for moving products and raw materials between locations or countries. There are about seventeen million intermodal containers in the world, and a large proportion of the world's long-distance freight generated by international trade is transported in shipping containers. In addition, it is estimated that several mil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bottle
A bottle is a narrow-necked container made of an impermeable material (such as glass, plastic or aluminium) in various shapes and sizes that stores and transports liquids. Its mouth, at the bottling line, can be sealed with an internal stopper, an external bottle cap, a closure, or induction sealing. Etymology First attested in 14th century. From the English word ''bottle'' derives from an Old French word ''boteille'', from vulgar Latin">-4; we might wonder whether there's a point at which it's appropriate to talk of the beginnings of French, that is, when it wa ... word ''boteille'', from vulgar Latin ''butticula'', from late Latin ''buttis'' ("cask"), a Latinisation (literature), latinisation of the Greek language, Greek βοῦττις (''bouttis'') ("vessel"). Types Glass Wine The glass bottle represented an important development in the history of wine, because, when combined with a high-quality stopper such as a cork, it allowed long-term aging of wine. ...

Plastic
Plastics are a wide range of synthetic polymers, synthetic or Semisynthesis, semisynthetic materials composed primarily of Polymer, polymers. Their defining characteristic, Plasticity (physics), plasticity, allows them to be Injection moulding, molded, Extrusion, extruded, or Compression molding, pressed into a diverse range of solid forms. This adaptability, combined with a wide range of other properties such as low weight, durability, flexibility, chemical resistance, low toxicity, and low-cost production, has led to their widespread use around the world. While most plastics are produced from natural gas and petroleum, a growing minority are produced from renewable resources like polylactic acid. Between 1950 and 2017, 9.2 billion metric tons of plastic are estimated to have been made, with more than half of this amount being produced since 2004. In 2023 alone, preliminary figures indicate that over 400 million metric tons of plastic were produced worldwide. If global trends ...

HDPE
High-density polyethylene (HDPE) or polyethylene high-density (PEHD) is a thermoplastic polymer produced from the monomer ethylene. It is sometimes called "alkathene" or " polythene" when used for HDPE pipes. With a high strength-to-density ratio, HDPE is used in the production of plastic bottles, corrosion-resistant piping, geomembranes and plastic lumber. HDPE is commonly recycled, and has the number "2" as its resin identification code. In 2008, the global HDPE market reached a volume of more than 30 million tons. Properties HDPE is known for its high strength-to-density ratio. The density of HDPE ranges from 930 to 970 kg/m3. Although the density of HDPE is only marginally higher than that of low-density polyethylene, HDPE has little branching, giving it stronger intermolecular forces and tensile strength (38 MPa versus 21 MPa) than LDPE. The difference in strength exceeds the difference in density, giving HDPE a higher specific strength. It is also harder and mo ...

Perylene
Perylene or perilene is a polycyclic aromatic hydrocarbon with the chemical formula C20H12, occurring as a brown solid. It or its derivatives may be carcinogenic, and it is considered to be a hazardous pollutant. In cell membrane cytochemistry, perylene is used as a fluorescent lipid probe. It is the parent compound of a class of rylene dyes. Reactions Like other polycyclic aromatic compounds, perylene is reduced by alkali metals to give a deeply colored radical anion and a dianion. The diglyme solvates of these salts have been characterized by X-ray crystallography. Emission Perylene displays blue fluorescence. It is used as a blue-emitting dopant material in OLEDs, either pure or substituted. Perylene can also be used as an organic photoconductor. It has an absorption maximum at 434 nm, and as with all polycyclic aromatic compounds, low water solubility (1.2 x 10−5 mmol/L). Perylene has a molar absorptivity of 38,500 M−1cm−1 at 435.7 nm.

Quinacridone
Quinacridone is an organic compound used as a pigment. Numerous derivatives constitute the quinacridone pigment family, which finds extensive use in industrial colorant applications such as robust outdoor paints, inkjet printer ink, tattoo inks, artists' watercolor paints, and color laser printer toner. As pigments, the quinacridones are insoluble. The development of this family of pigments supplanted the alizarin dyes. Synthesis The name indicates that the compounds are a fusion of acridone and quinoline, although they are not made that way. Classically the parent is prepared from the 2,5-dianilide of terephthalic acid (C6H2(NHPh)2(CO2H)2). Condensation of succinosuccinate esters with aniline followed by cyclization affords dihydroquinacridone, which are readily dehydrogenated. The latter is oxidized to quinacridone. Derivatives of quinacridone can be readily obtained by employing substituted anilines. Linear ''cis''-Quinacridones can be prepared from isophthalic aci ...

Azo Compound
Azo compounds are organic compounds bearing the functional group diazenyl (, in which R and R′ can be either aryl or alkyl groups). IUPAC defines azo compounds as: "Derivatives of diazene (diimide), , wherein both hydrogens are substituted by hydrocarbyl groups, e.g. azobenzene or diphenyldiazene.", where Ph stands for phenyl group. The more stable derivatives contain two aryl groups. The group is called an ''azo group'' (, ). Many textile and leather articles are dyed with azo dyes and pigments. Aryl azo compounds urinary tract infections">Phenazopyridine, an aryl azo compound, is used to treat urinary tract infections">150px Aryl azo compounds are usually stable, crystalline species. Azobenzene is the prototypical aromatic azo compound. It exists mainly as the Cis-trans isomerism, ''trans'' isomer, but upon illumination, converts to the Cis-trans isomerism, ''cis'' isomer. Aromatic azo compounds can be synthesized by azo coupling, which entails an electrophilic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Isoindoline
Isoindoline is a heterocyclic organic compound with the molecular formula C8H9N. The parent compound has a bicyclic structure, consisting of a six-membered benzene ring fused to a five-membered nitrogen-containing ring. The compound's structure is similar to indoline except that the nitrogen atom is in the 2 position instead of the 1 position of the five-membered ring. Isoindoline itself is not commonly encountered, but several derivatives are found in nature and some synthetic derivatives are commercially valuable drugs, e.g. lenalidomide and pazinaclone. Substituted isoindolines 1-Substituted isoindolines and isoindolinones are chiral. Isoindolylcarboxylic acid and 1,3-disubstituted isoindolines are constituents of some pharmaceuticals and natural products. Isoindolines can be prepared by 1,2-addition of a nucleophile onto a bifunctional ε-benzoiminoenoates followed by intramolecular aza-Michael reaction. Another route involves +2cycloaddition of the azomethine ylides (e.g. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nucleation
In thermodynamics, nucleation is the first step in the formation of either a new Phase (matter), thermodynamic phase or Crystal structure, structure via self-assembly or self-organization within a substance or mixture. Nucleation is typically defined to be the process that determines how long an observer has to wait before the new phase or self-organized structure appears. For example, if a volume of water is cooled (at atmospheric pressure) significantly below 0°C, it will tend to Freezing, freeze into ice, but volumes of water cooled only a few degrees below 0°C often stay completely free of ice for long periods (supercooling). At these conditions, nucleation of ice is either slow or does not occur at all. However, at lower temperatures nucleation is fast, and ice crystals appear after little or no delay. Nucleation is a common mechanism which generates first-order phase transitions, and it is the start of the process of forming a new thermodynamic phase. In contrast, new phas ...

Milk Crate
Milk crates are square or rectangular interlocking boxes that are used to transport milk and other products from dairies to retail establishments. In English-speaking parts of Europe the term " bottle crate" is more common but in the United States the term "milk crate" is applied even when the transported beverage is not milk. History The dimensions of the milk crate may have been influenced by the dimensions of the tea chest. For all practical purposes, both hold similar internal volumes, but tea chests are designed for shipping over the open ocean. The bottle crate emerged after the tea chest was a de facto shipping method. The plastic milk crate is an Australian invention, produced through a period of trial and error in design by the Dairy Farmers Cooperative Milk Company in the 1950s and 60s. Design Middle 20th century bottle crates were made of wood, later ones were stainless steel, and those made in the latter part of the century were of heavy-duty polyethylene. ...

Reusable Packaging
Reusable packaging is manufactured of durable materials and is specifically designed for multiple trips and extended life. A ''reusable package'' or container is "designed for reuse without impairment of its protective function." The term returnable is sometimes used interchangeably but it can also include returning packages or components for other than reuse: recycling, disposal, incineration, etc. Typically, the materials used to make returnable packaging include steel, wood, polypropylene sheets or other plastic materials. Reusability of packaging is an important consideration of the environmental credo of "reduce, reuse, and recycle". It is also important to the movement toward more sustainable packaging. Returnable packaging is encouraged by regulators. Shipping containers For many years, several types of shipping containers have been returnable and reusable. These have made most sense when a reverse logistics system is available or can be readily developed. A return, recondi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
