一、產品用途（Product Usage）

塑料拉西環具有異的耐酸耐熱性能，能耐除氫氟酸以外的各種無機酸、酸及溶劑腐蝕，可在各種高溫場合使用，應用范圍十分廣泛。

Lassi ring has different acid and heat resistance, can resist all kinds of inorganic acids, acids and solvent corrosion except hydrofluoric acid, and can be used in various high temperature occasions, and the application range is very wide.

塑料拉西環填料的發明使得填充塔有了穩定一致的可靠性能，拉西環顯著的提高了操作性能。塔的傳質分離效率很高。由于拉西環的成本低，拉西環被廣泛使用的一種化工填料。

The invention of the Lassie ring packing has enabled the filling tower to have stable and consistent reliable performance, and the Lassie ring has significantly improved the operating performance. The mass transfer separation efficiency of the tower is very high. Due to the low cost of lassi rings, rassie rings are widely used as a chemical filler.

二、適用范圍（Scope of application）

塑料拉西環可用于化工、冶金、煤氣、等行業的干燥塔、吸收塔、冷卻塔、洗滌塔、塔等。

Can be used in chemical, metallurgy, gas, and other industries of drying tower, absorption tower, cooling tower, scrubbing tower, tower, etc.

塑料拉西環外形簡單，高度與直徑的尺寸相等。大尺寸的拉西環（100MM以上）一般采用整砌方式規則填充，而75MM尺寸以下的拉西環一般采用亂堆方式裝填。

The shape is simple, and the height is equal to the size of the diameter. Large-sized Lassie rings (more than 100MM) are generally filled in a neat manner, while Rassy rings below 75MM are generally filled in a haphazard manner.
