SJSZ series cone-shaped twin screw plastic profile extrusion lines/ Wood plastic profile extrusion line Product Introduction: This line is mainly used to produce kinds of door and window profile, clapboards, ceilings, etc.with PVC, PP, etc as materials.
Alumina-spinel castanles(QGBJ-90 and QGBJ-85) mainly comsist of fused white corundum,sintered tabular corundum and pure synthesized spinel.The castables are highly resistant to slag corrosion and penetration when employed as lining in con-cast ladles.High alumina-spinel castables (QGBJ-80 and QGBJ-75) are composed of sintered special grade bauxide and synthesized spinel from natural raw materials.The castables have strong resistance to corrosion,erosion and thermal shock.The service life of high alumina-spinel castables is 1~3 times higher than that of sodium silicate bonded alumine-magnesia c

The ZN Oil regeneration system (Model ZYD-I) has been specially designed for on site use to completely regenerate insulating oils in energized or de-energized transformers especially for the power, which is over 110KV. The ZYD-I system provides regular oil purification such as degassing, drying and particulate removal but also can remove acidity, sludge, other soluble oil decay products and discoloration. This is accomplished by the use of high vacuum degasification technology and particulate filters combined with our special brand of earth. After treating, the oil can be used as new.
By using advanced technology,the clay insulating refractory bricks is featured with homogeneous structure,high mechanical strength,precise size,low thermal conductivity and long service life.The brick is widely used in the insulating layers and linings of various heat engineering equipments such as hot blast stove,coke oven,heating furnace,boiler,tunnel kiln and so on,which saves over 30% energy.It is one of ideal insulating materials for energy saving.
