Provides a thin and resistant film with high affinity to the metallic surfaces. does not descale once applied on stainless steels, carbon steels, chromes bronze, titanium, aluminum etc
提供薄膜和抗高吸引力膜，保持金屬的光澤表面，當用在不? ? ? 、碳鋼、鉻銅、鈦、鋁時，不會結垢。 -
A solid - liquid fluidized bed has been designed and installed, which will be used in the heat exchanging and descale field. the experimental study for distributor design was carried out and the particles distribution in the tubes of the solid - liquid fluidized bed under different operating conditions was studied by using the ccd measure system. experimental results show that heterogeneous pores distributor which was arranged in the inlet chamber of the solid - liquid fluidized bed can improve the nonuniform distribution of particles in the pipe bundle under high flow rate. the nonuniform decreases by decreasing the mount of pore, but the solid holdup decreases too. the particles distribution is influenced by the position of the heterogeneous pores distributor
實驗結果表明：在液固循環流化床進口段安裝可調節高度的變孔徑分佈板，能在較高的流速下，較好的改善固體顆粒在管束中的不均勻分佈；開孔率越小固體顆粒在管束中的分佈越均勻，但管束中粒子的平均固含率也越小；分佈板的安裝高度對顆粒的分佈有很大的影響，在實驗范圍內分佈板的安裝距離管束入口處越遠，顆粒在管束中的分佈越均勻。
