polyethylene (LDPE), biorefinery performance should be improved further by more efficient utilization of sodium hypochlorite during PHA extraction, minimization of methane leakage in biogas facilities, upgrading of biogas to biomethane, and more effective handling of the liquid fraction from digestate ...
Electronic configuration is defined as the distribution of electrons into the orbitals of an atom. Every neutral atom consists of a fixed number of electrons which is equal to the number of protons and is called the atomic number. Apart from electrons and protons, an atom also has neutrons whi...
The intention of the work was to develop easy to use technical design methods which are helpful for the daily work of the process engineer, and which also ... Schuler,Werner - 《Swansea University》 被引量: 1发表: 1996年 Method to Evaluate the Homogenization of Bimodal Polyethylene in a Co...
Migration of antimony from PET bottles into beverages: determination of the activation energy of diffusion and migration modelling compared with literature... Plastics bottles made from polyethylene terephthalate (PET) are increasingly used for soft drinks, mineral water, juices and beer. In this study...
The invention comprises a textured plastics film of material, in particular thermoplastic material, which can be rendered harder by stretching, for example of polyethylene, polypropylene, polyamide, polyvinylchloride or the like. The said film has, with one another, preferably alternating over the ...
polyethylenesolid fillersThe high potential of layered silicate improving material properties of plastics has been discussed in a significant number of publications. However, homogeneously dispersing it with twin screw extruders is demanding. Available information on optimum screw configuration...
[Also in Group VIII] Plastics, e.g. polyethylene, polyvinylchloride, polystyrene and cellulose esters, are compressed e.g. longitudinally with the aid of a thick apron or belt 28, e.g. of soft rubber which is flexed between a roll 29 and rolls 26, 27 so that the plastic is thickened...
The tube which may be made of polyethylene, polypropylene, polyvinyl chloride or polystyrene, may be softened by heating, e.g. in oil, and pressed into the slot and after cooling it is secured by the retained shape. An adhesive may be applied to the joint surfaces and a resilient sealing...
In this work, the feasibility of using recycled agricultural plastics in the manufacture of tube shelters for plant seedlings, which can be used in forest restoration and other plantations, has been investigated. The recycled plastics and their blends with a virgin polyethylene were characterized ...
The invention relates to a method and an apparatus for inspecting and ensuring the usability of plastics containers with grip handles, e.g. bottle grates made of polyethylene or the like. A simple and reliable elimination of plastics grates with a broken or cracked grip handle is distinguished ...
