Process is particularly important.
《The preparation and its performance study of expansible fire retardant low-density polyethylene》One literary author is poly- for current low-density
There is the technical barrier of poor water resistance during vinyl material halogen-free flameproof, using macromolecular carbon forming technology and encapsulation skill
The mode that art combines, development of new is water-fast halogen-free expanded flame-retardant LDPE Composite, wherein carbon forming agent select three
The APP of piperazine analog derivative CFA, dehydrant and foaming agent from Silica hydrogel parcel, this new Low Density Polyethylene material
Material not only has higher thermal stability and fire resistance, while also overcoming the difficulty of poor water resistance.Although present invention solution
Low density polyethylene fire retardant of having determined is poor, the problem of poor water resistance, improves polyethylene safety coefficient in use, but
Be Low Density Polyethylene however for high pressure field direct current cables in running, the low conductivity characteristic of polyethylene is caused
The space charge of accumulated inside is difficult to spread, and causes the Severe distortion of local field strength, especially when there is temperature in oepration at full load
During Gradient Effect, this phenomenon is even more serious, when surface of insulating layer local field strength reaches certain value, will cause shelf depreciation,
The insulation ag(e)ing phenomenon such as resinification, substantially reduces the service life of cable, to this improve polyethylene anti-flaming, water resistance it is same
When, improve its insulating properties and particularly seem urgent.
