發泡機設備:將發泡劑起發到鋼管與防腐層之間從而起到產品使用中保溫的作用。發泡機運行時將兩個料罐中的物料通過比例計量泵壓入發泡槍中,發泡槍中同時輸送高壓氣流將混合料打入防腐層與鋼管之間,變頻調節比例計量泵的速度可以滿足不同鋼管所需發泡層的密度。 Foaming machine: the foaming agent is sent between the steel pipe and the anti-corrosion layer to play the role of heat preservation in the use of the product. During the operation of the foaming machine, the materials in the two material tanks are pressed into the foaming gun
