介紹? Introduction

擴(kuò)散機(jī)型號(hào)250被設(shè)計(jì)為一個(gè)通用氣溶膠烘干機(jī)。烘干機(jī)的一個(gè)進(jìn)水陷阱在去除粗水滴。 The Diffusion Dryer Model 250 is designed as a general-purpose aerosol dryer. A water trap at the inlet of the dryer removes coarse water droplets. 氣霧劑，然后通過(guò)一個(gè)可移動(dòng)的磁帶含有硅凝膠。 The aerosol is then passed through a removable cartridge containing the silica gel. 墨盒是由兩個(gè)同心圓筒，一個(gè)內(nèi)細(xì)絲網(wǎng)屏幕和一個(gè)外網(wǎng)的屏幕。 The cartridge is formed by two concentric cylinders, an inner fine wire mesh screen and an outer wire mesh screen. ? ?由于氣溶膠墨盒穿過(guò)的內(nèi)管，水蒸汽擴(kuò)散通過(guò)篩網(wǎng)進(jìn)入硅膠。 As the aerosol goes through the inner cylinder of the cartridge, the water vapor diffuses into the silica gel through the mesh screen. 硅膠是一個(gè)不規(guī)則的珠子無(wú)定形二氧化硅，這是很難綜合或制作的不規(guī)則的形式硬顆粒。 Silica gel is an amorphous form of silicon dioxide, which is synthetically produced in the form of hard irregular granules or hard irregular beads. 阿聯(lián)鎖微腔多孔結(jié)構(gòu)提供了一個(gè)非常高的表面積（每克800平方米）。 A micro porous structure of interlocking cavities gives a very high surface area (800 square meters per gram). 正是這種結(jié)構(gòu)使得高容量的硅膠干燥劑。 It is this structure that makes silica gel a high capacity desiccant. 堅(jiān)持以水分子凝膠表面，因?yàn)樗憩F(xiàn)出了周圍的空氣低蒸氣壓比。 Water molecules adhere to the gels surface because it exhibits a lower vapor pressure than the surrounding air. 當(dāng)壓力達(dá)到平衡，不再發(fā)生吸附。 When pressure equilibrium is reached, no more adsorption occurs. 硅凝膠的美麗，是其內(nèi)部的物理吸附的水蒸汽進(jìn)入毛孔。沒(méi)有化學(xué)反應(yīng)，沒(méi)有按產(chǎn)品或副作用。即便飽和水蒸汽，硅膠仍具有形狀外觀干燥的產(chǎn)品，其不變。 The beauty of silica gel is the physical adsorption of water vapor into its internal pores. There is no chemical reaction, no by products or side effects. Even when saturated with water vapor, silica gel still has the appearance of a dry product, its shape unchanged. 硅膠是一種很容易再生的烤箱在250 ° F的3個(gè)小時(shí)。 The silica gel is easily regenerated in an oven at 250°F for three hours.
