Foaming agent material Description:
       The so-called physical blowing agent is to make the object into the hole of the substance, which can be divided into chemical blowing agents and physical blowing agents and surfactants three categories. Chemical blowing agents are those compounds decompose upon heating to release carbon dioxide and nitrogen gas, and the formation of pores in the polymer composition; physical blowing agents is the pore foam through the physical form of a substance changes that by compressing the expanding gas, volatile liquid or dissolved solids formed; blowing agents have high surface activity, can effectively reduce the surface tension of the liquid, and the liquid film surface electric double layer arrangement and surrounded by air , the formation of bubbles, and then by a single bubble foam composition. 
Foaming agent material process parameters and process requirements:
1, the initial moisture content of 25%
2 required moisture content: 1%
3, the original state of the material: fluffy cake
4, product characteristics: Bulk Density 500kg / M3
5, material collection methods : cyclone, bag filter
6, the finished diameter; 10 ~ 20μm
foaming agent drying and pneumatic conveying process outlined:
       after junior high efficiency air filter ambient air after the steam is fed by a blower to heat radiators process set temperature, flash drying into the host, and through the screw feeder into the drying machine to be dried cake, complete the drying process of heat and mass transfer in drying machine, gas-solid mixture of a cyclone, baghouse separation, filtration, the material is separated from the gas out of the drying system, drying system exhaust, exhaust from the induced draft fan into the atmosphere. 
       Product discharged from the cyclone by pneumatic conveying suction draft fan staging hopper, to be packaged.
