A concrete pump is a machine used for transferring liquid concrete by pumping. There are two types of concrete pumps. The first type of concrete pump is attached to a truck or longer units are on semi-trailers.
A cylinder or tank is a pressure vessel for storage and containment of gases at above atmospheric pressure. High-pressure gas cylinders are also called bottles. Inside the cylinder the stored contents may be in a state of compressed gas, vapor over liquid, supercritical fluid, or dissolved in a substrate material, depending on the physical characteristics of the contents. A typical gas cylinder design is elongated, standing upright on a flattened bottom end, with the valve and fitting at the top for connecting to the receiving apparatus.
Translucent ceilings are a general term for new decorative interior roofing materials. The appearance can be Clouds, Vertical and 3 Dimensional.
People have been working to make all the devices on the desktop wireless, from wireless networks to screencasting, from wireless mice to Bluetooth speakers, but wireless technology only solves the problem of data signal transmission between devices. These devices still need a wire. To provide power. Until the popularity of wireless charging technology, we can finally get rid of the constraints of the wire.
The thermal print head consists of a row of heating elements, all of which have the same resistance. These components are densely packed, ranging from 200 dpi to 600 dpi. These components will quickly generate high temperatures when passing a certain current. When these components are applied, the temperature rises in a very short period of time, and the dielectric coating reacts chemically to give color.
Phycocyanin is a pigment-protein complex from the light-harvesting phycobiliprotein family, along with allophycocyanin and phycoerythrin. It is an accessory pigment to chlorophyll. All phycobiliproteins are water-soluble, so they cannot exist within the membrane like carotenoids can. Instead, phycobiliproteins aggregate to form clusters that adhere to the membrane called phycobilisomes. Phycocyanin is a characteristic light blue color, absorbing orange and red light, particularly near 620 nm (depending on which specific type it is), and emits fluorescence at about 650 nm (also depending on which type it is). Allophycocyanin absorbs and emits at longer wavelengths than phycocyanin C or phycocyanin R. Phycocyanins are found...
Diamond is a solid form of the element carbon with its atoms arranged in a crystal structure called diamond cubic. At room temperature and pressure, another solid form of carbon known as graphite is the chemically stable form, but diamond almost never converts to it.
DLC classification, it organized DLC types on a pseudo ternary phase diagram and clarified the relationship with deposition methods. DLC films formed with the sputter vapor deposition method and arc PVD method do not contain hydrogen as long as only solid graphite is used as the raw material and no hydrocarbon gas is used. They are characterized by the differences in the amount of sp3-bonded carbon and the structure of the cluster within the range from graphite-like carbon (GLC) that does not contain hydrogen and amorphous carbon (a-C) to tetrahedral amorphous carbon (ta-C).
Nonionic surfactants have covalently bonded oxygen-containing hydrophilic groups, which are bonded to hydrophobic parent structures. The water-solubility of the oxygen groups is the result of hydrogen bonding. Hydrogen bonding decreases with increasing temperature, and the water solubility of nonionic surfactants therefore decreases with increasing temperature.
Soldering Tin an important industrial raw material for connecting electronic components in welding lines. It is a kind of solder with low melting point, mainly referring to solder made of tin-based alloy.
