According to the conventional practice, concrete transportation during high-rise construction relies on tower cranes to transport concrete up and down. If this method is applied to the construction of Shanghai World Financial Center, it takes at least half an hour to transport concrete back and forth, and the construction period will be greatly constrained. For this purpose, the builder uses a super-pumping method to place concrete into a pipe with a diameter of 125 mm and a height of 600 m, which is pumped upwards.
Power is an important core technology to transport concrete to 492 meters. The pump designed specifically for the World Financial Center project provides extremely strong pressure, which is equivalent to pressing 350 kilograms of weight on the size of the fingernail.
PE blowing agent is yellow powder, it is non toxic, odorless and flammable.
Azodicarbonamide is a universal high temperature foaming agent and has good compatibility and dispersity.
Blowing agent yellow powder can be stored in normal temperature for long time. It will decompose, when the temperature is over 120.
Applications
Azodicarbonamide powder is widely used in EVA,PVC,PS,PP,PE,Rubber,XPE etc.
Blowing Agent is particularly applicable for hot-press small mold & big mould of PE and free style of rubber& plastic compound; commonly applied in MD pelleting injection of EVA, compression molding of PE&PVC, extrusion&coating of PVC, and compression molding & extrusion of rubber& plastic compound. Widely applied in high density EVA PE MD sole, NBR+PVC insulation materials, and handle of sports equipment.
