SAWDUST BRIQUETTES BRIQUETTES: Manufactured from wood, however, the compression process that forms the block and Japanese heating technology is the biggest difference compared to conventional black charcoal. Charcoal sawdust characteristics are not much different from binchotan white coal. Both types are high-grade clean smokeless coal with extremely high heat and carbon content. Humidity, ash, and sulfur content are extremely low. Sawdust charcoal and binchotan charcoal are considered the most advanced BBQ charcoal in the world today. Sawdust charcoal has many advantages compared to black charcoal, coconut shell charcoal with relative price. In the charcoal market in Vietnam today, sawdust coal is very popular and widely used. The biggest difference between coconut shell charcoal and sawdust charcoal is that the charcoal sawdust is produced by pressing the wood into a bar before firing and cooling. This process removes most impurities, volatile matter, tar in coal. As for coconut shell charcoal and briquettes, the materials used are coconut shell charcoal powder or ground coal powder pressed into charcoal. The natural material is carbonized into charcoal with a simpler technology, resulting in coal quality that is not comparable to sawdust or white coal. SPECIFICATIONS: Length: 10 - 20 cm Heat: 7650 KCal / kg. Ash: 5% Humidity: 3 - 4% Volatility: 10% Sulfur: 0.05% Moisture: 10% max Carbon: 70% min

1. Product Overview VHC spherical Bearings/ Bridge bearing manufactured by Vinh Hung Investment and Production Company Limited (Vinh Hung IP) are capable of withstanding the high loads and movements suitable for structures requiring the rotary angle equal or bigger than 0.015 rad in all directions. VHC spherical bearings are designed and manufactured according to current standards such as: TCVN 11823, AASHTO LRFD, ASTM D5977, EN 1337, 2. PRODUCT CHARACTERISTICS VHC spherical bearings/ bridge bearing possesses a bottom plate (6) which has a PTFE sliding plate (4) on it is upper curved surface. A convex calotte (5) is placed on top of this, which, thanks to it is polished hard-chromium plated surface, can slide within the lower part with low friction, thus facilitating rotations about every axis. A second sliding plate of PTFE (4) is recessed into the upper surface of the calotte. Together with the upper plate (2) above it, this accommodates longitudinal and/or transverse sliding movements of the superstructure, if required. To reduce sliding resistance to a minimum, the lower surface of the top plate features a polished stainless steel sheet. In the case of bearings which should allow movement along one axis only, the direction of movement is controlled by guiding bars (3). In the case of fixed bearings, the top plate does not have a stainless steel sheet. The bearing is connected to the superstructure and the substructure by means of anchor dowels (1) or threaded sleeves (depending on design), or alternatively by means of separate anchor plates with shear studs. To ensure the long-life durability, VHC spherical bearings are protected against corrosion by the following methods: coating with two-component epoxy, PU-based painting (Polyurethane), hot-dip galvanization according to ASTM A123 standards and especially the Al-Mg spray coating method (at the ratio of 5% Al and 95% Mg) which ensure the anti-corrosion durability of up to 100 years, this method is proved by the salt-spraying test in 6000 hours (8-hour dry-wet cycle) according to ASTM B117
