粗心大意的代价

王昌京

一日维修格力1.5匹不制冷机(启动电容变质),当外机检修完成运行正常后,见外机有一支架固定螺丝与墙面有1厘米的空隙,就顺手拿了一把活动板手,固紧一下,由于该机装了两年可不是那么好紧的,只好加劲呗!后果是板手滑脱,手腕碰上角钢划一道血口子,80元辛苦钱送给大夫.
还有一次装分体新机是远郊区,在联结配管与内机时也是随手拿起两把活动板手,天气很热、人感觉很累,紧固力度没掌握好将丝弄坏(滑丝),在用户许可情况下,只好切下接头胀管焊接.劳神费力不讨好啊!
我告戒大家:在使用板手时,最好是开口呆板手根据大小合理选用,制冷大多为铜质螺丝力度掌握要合适,活动板手虽方便但间隙游动太大,今年夏天又快来了,为了操作方便、您的安全,请选用开口呆板手.

不一定要用呆坂手，粗管用300MM的，细管用200MM的活扳手。很容易掌握力度。

Barium Titanate Nanoparticles , nanopowder, nanodots or nanocrystals are spherical or faceted high surface area nanocrystalline alloy particles with magnetic properties. Nanoscale Barium Titanate Particles are typically 20-40 nanometers (nm) with specific surface area (SSA) in the 30 - 50 m 2 /g range and also available in with an average particle size of 100 nm range with a specific surface area of approximately 7 m 2 /g. Nano Barium Titanate Particles are also available in ultra high purity and high purity and coated and dispersed forms. They are also available as a nanofluid through the AE Nanofluid production group. Nanofluids are generally defined as suspended nanoparticles in solution either using surfactant or surface charge technology. Nanofluid dispersion and coating selection technical guidance is also available. Surface functionalized nanoparticles allow for the particles to be preferentially adsorbed at the surface interface using chemically bound polymers. Development research is underway in Nano Electronics and Photonics materials, such as MEMS and NEMS, Bio Nano Materials, such as Biomarkers, Bio Diagnostics & Bio Sensors, and Related Nano Materials, for use in Polymers, Textiles, Fuel Cell Layers, Composites and Solar Energy materials. Nanopowders are analyzed for chemical composition by ICP, particle size distribution (PSD) by laser diffraction, and for Specific Surface Area (SSA) by BET multi-point correlation techniques. Novel nanotechnology applications also include Quantum Dots. High surface areas can also be achieved using solutions and using thin film by Sputtering Targets and evaporation technology using pellets, rod and foil. Applications for Barium Titanate Nanocrystals include for their dielectric properities and in the capacitors for microelectronics and future nano-electronics. Additional technical, research and safety (MSDS) information is available.
Barium is a Block S, Group 2, Period 6 element. The electronic configuration is [Xe] 6s2. In its elemental form barium's CAS number is 7440-39-3. The barium atom has a radius of 217.4.pm and it's Van der Waals radius is 200.pm. Barium is a member of the alkaline-earth metals. It has technical applications in glass, electronics and medicine. It is also used in paints and colorants. Electronic coatings based on barium titanate are essential to cell phones and other microelectronics. It has long been used in medical diagnostic techniques because it makes a good x-ray contrast medium. Barium is a dopant in various fluorescent lamp coating formulas.
