Football shin guard board is an effective protective device that must be worn in the formal competition, which can protect the players to reduce the injury. Moreover, the history of shinguard board has a long history. Today’s Baibai safety net introduces how the football shinguard board is classified. Generally speaking, according to the type of

In order to support the development of football, our company recently reached a cooperation agreement with the football club. We were provided a number of football skin guards for the girls’ football team, which was highly praised by the coaches and athletes.

Compared with chemical foaming, the foaming degree of physicalfoaming can be improved obviously. Taking PE as an example, thehighest foaming degree reached by chemical foaming is 50%, andthe maximum foaming degree reached by physical foaming is 80%. In the production of cable products different, generallyreached the foaming degree is different, for example: the .chemical foaming,

As a mature and rel iable process, physical foaming has beenfully accepted by the cable market and has been widely used inactual production instead of chemical foaming process. Generally used foam insulation materials, inc luding polyethylene (PE) and fluorine plastic (FEP), can be used forcommunications cables, data cables, coaxial cables and radiofrequency cables. Because of

The primary raw material used for the synthesis of commercially important polymers has been petroleum for the last 50 years. The synthesis of polymers from renewable resources such as plant and animal prod- ucts is attractive because of diminishing reserves and the increasing price of petroleum. Social acceptance of polymers from renewable, agricultural raw materials

A process for purifying Maleic Anhydride Modified graft polyolefin comprises adding an aqueous solution of alkali metal hydrox­ ide to a solution of a maleic anhydride graft polyolefin contain­ ing unreacted maleic anhydride and dissolved in an organic solvent at a temperature from 80°C to 160°C. Thereby precipi­ tating Maleic Anhydride Modified graft polyolefin particles

The whiteboard must be written with a special whiteboard pen. Because of Point 3, it is sometimes deliberately called non-blackboard in Taiwan. Whiteboard pens contain chemical ingredients, and they smell good.The service life of whiteboard depends entirely on the protection degree of the board surface! 1.When using Dry Erase Board for the first time, be

Dry Erase Board is a writing plane made of usually white metal board material. The function of Dry Erase Board is similar to that of blackboard. It is a writing tool that can be erased repeatedly. Usually used in teaching, conference discussions, or personal and family notes. This erasable Dry Erase Board produced by our

The aim of this study was to compare the protective effectiveness of polypropylene based shin guards with custom-made carbon fiber ones. In football, injuries from opponent contact occur commonly in the lower extremities. FIFA the world’s governing body for football requires players to wear shin guards. Three commercial polypropylene soccer shin guards and two custom-made

The theoretical and experimental data on the breakup of droplets are reviewed. Several factors influence development of droplets: flow type and its intensity, viscosity ratio, elasticity of polymers, composition, thermodynamic interactions, time, etc. For Newtonian systems undergoing small, linear deformation, both the viscosity ratio and the capillary number control deformability of drops. On the other
