Recently, the first session of the national medical robots and medical intelligent conference held in Chengdu, a series of exoskeleton robots developed independently by China debuted in Chengdu and made a stunning appearance. It is reported that this set of wearable exoskeleton robot equipment, according to the intention of human behavior to control the robot system, with the realization of walking, rehabilitation training and support functions. The robot can sense the intention of the human body through the exoskeleton sensor The robot uses a bio-mechanical and electrical integration system, the electric drive joint, mechanical connecting rod, smart shoes, waist support and tied accessories and other components. At work, the exoskeleton sensor first perceives the intent of the human body to transmit the information to the computer rapidly. Then, through the control module to convey commands to achieve electric drive joints, mechanical connecting rod, smart shoes, lumbar support and binding accessories efficient operation, to help users move freely. At the scene, the staff wear the exoskeleton robot equipment, press the button on the smart crutches in his hand, foot pedal will make the induction, and make forward action. It is reported that the exoskeleton robot similar to the metal exoskeleton armor, about 1 meter high, weighing about 38 pounds, from top to bottom with more than a dozen joints, dozens of sensors ... High paraplegia patients wear, not only to re-stand It can also walk like a normal person when going up and down the stairs.
Sodium Tripolyphosphate, also Food Grade Stpp, or Stpp Detergent Powder,is an inorganic compound with formula Na5P3O10. Stpp Sodium Tripolyphosphate is the sodium salt of the polyphosphate penta-anion, which is the conjugate base of triphosphoric acid. It is produced on a large scale as a component of many domestic and industrial products, especially detergents. Environmental problems associated with eutrophication are attributed to its widespread use in Water Treatment.
The majority of STPP is consumed as a component of commercial detergents. It serves as a "builder," industrial jargon for a water softener. In hard water (water that contains high concentrations Ethylene-Vinyl Acetate of Mg2+ and Ca2+), detergents are deactivated. Being a highly charged chelating agent, TPP5− binds to dications tightly and prevents them from interfering with the sulfonate detergent.
Because it is very water-soluble, STPP is not significantly Pvc Resin removed by waste water treatment. STPP hydrolyses to phosphate, which is assimilated into the natural phosphorus cycle. Detergents containing phosphorus contribute to the eutrophication of many fresh waters.
