Plastic Crates

The quantity of these materials is relatively small compared with the amount of waste high-density poly(ethylene) produced each year. Containers made from HDPE are widely used for detergents, oil, and antifreeze, and enormous amounts of material are used in disposable applications aimually. In principle recycled poly(ethylene) could be used for drain pipes, flower pots, dustbins, and plastic crates. The problem remains, however, that economics do not favour recycling of these polymers and in the absence of Government intervention little or nothing can be done to alter commercial attitudes towards recycling.

The samples should be secured upright in a plastic crate or box and transported carefully to the next location or to the Survey base for further drying. 

Plastic crates and boxes are usually injection molded from HDPE or PR They are available in a variety of sizes and designs. Most of these are designed to be reusable, and often will either collapse or nest to minimize space requirements when they are not in use. 

Until a few years ago, the red pigment for coloring containers, toys, household wares, plastic crates, etc. was Cadmium Red. This is Cadmium sulfoselenide red, C9Hi3CdN204SSe (CAS 58339-34-7), also known as Pigment Red 108 (see Chemnet 2015). The cadmium compound is now considered environmentally undesirable, so it is being replaced by the non-toxic Cerium(III) sulphide (Cc2S3 CAS 12014-93-6). This compound gives a rich red color and is stable up to 350 °C (Emsley 2001).

Tlie indi ddual cells are assembled into batteries after a leakage test to check for faulty welding joints in steel containers or cracks and improper seals in the plastic encased cells. Cells that are to be delivered without electroltye are emptied after the fomiation cycles. Tlie steel-cased cells hav e to be separated by mechanical means to prevent intercell shorts and are often assembled into wooden crates. Tlie cells in plastic cases can be cemented together or strapped with tape.

Worm bins can be purchased, or you can make your own—or adapt existing containers such as wooden crates or boxes, or a plastic storage bin. As worms like to feed near the surface, the most effective bins have a relatively large surface area. There is no need for the container to be "wormproof" the worms will stay put if the conditions are right for them. Good drainage is vital, as kitchen waste can produce... 

Plastic fuse is routinely used as a fuse extension to quickmatch or piped match, especially when firing rockets, mines or shells. In the latter case, the piped match fuses from a crate of, say, ten shells connected via a single length of plastic fuse which will burn progressively to ignite each of the ten shells in turn. 

It can be found as a substitute for natural materials in plastic bags, sandwich boxes, washing-up bowls, wrapping film, milk-bottle crates and washing-up liquid bottles (Figure 14.15). 

General rules for the occurrence of stress corrosion cannot be given, since the phenomenon is very specific for certain combinations of polymer and environment, and is also dependent on the processing conditions in manufacturing the article (such as the occurrence of cooling stresses and orientations). When plastics are used in articles which are subjected to mechanical stress, such as pipes, crates, bottles, screw-caps, etc., the risk of stress corrosion in the presence of fat, soap or organic liquids, should always be taken into account. Proper choice of material and dimensions can minimize the occurrence of crack formation.

Except for the expensive cobalt green, chromium oxide is the only green pigment that meets the high color stability requirements for building materials based on lime and cement [3.80]. In plastics, however, chromium oxide green is only of minor importance because of its dull tint, but is widely used in coloring beer crates. 

If the hole is in the bottom of the bucket rather than the side, the bucket will have to be supported so that the hose can connect to the fitting. For bottom drain reservoirs of this size, at most discount stores you can find a plastic cube crate (like milk crates). The hose can fit through any of the spaces in the crate wall, and the crate provides solid support for the reservoir. If the outlet is on the side, and high enough for the hose and fitting to clear the ground/floor, you don t need to elevate the reservoir. 

Secondary- packaging, or collection packaging such as cardboard boxes, wooden crates, or plastic containers used to carry quantities of primary packaged goods. 

The prime containers in warehousing and distribution could be protected with plastic boxes or in wooden crates, which could be made returnable and therefore reusable. This would entail the problem of retrieving the containers, cleaning (thereby creating effluent), re-marking them and putting them into the cycle. 

Drums, crates and trays are designed in such a way that when stacked in multi-tiered layers each interlocks with the one below. Trays, for example, can have plastic inserts or integral designs at each comer to support the tray above. 

Plastics make up only about 8 percent of the volume in the average landfill but represent a huge investment of energy and raw materials. Most plastics produced from petroleum materials by polymerization of monomers such as ethylene or vinyl chloride are thermoplastic materials and can be cleaned, melted, and re-formed. Thermosetting plastics can also be cut into pieces that are mixed with other plastics or used as fillers. High-density polyethylene (HDPE) and polyethylene terephthalate (PETE) are the most widely reused plastic materials, but polyvinyl chloride (PVC), polypropylene, and polystyrene account for 5 percent of the recycled plastics. In 2001 80 million pounds (36 milfion kilograms) of plastics were recycled in the United States. Recycled plastic materials are used in the production of bottles, fabrics, flowerpots, furniture, plastic lumber, injection molded crates, and automobile parts.
