看到PP，想必大家都猜到了实验室通风橱的材质了，pp它是我国常用的聚丙烯材料，具有耐酸碱、耐腐蚀、耐高温、高精度、易清洗、组合灵活、安装方便、美观耐用等特点5mm厚PP聚丙烯板焊接生产， 具有很强的耐酸碱性和耐腐蚀性，安装在工作空间的后部和上部，由两块板组成，在工作空间与排气管道的连接处形成气室，均匀排放污染气体，使用导流板PP固定底座与柜体结合。塘树科技公司制作的台面一般采用（国产）实心理化板（12.7mm厚）抗冲击、耐腐蚀、甲醛E1或使用等级标准8mm厚优质纯料PP（聚丙烯）板。
关于实验(yan)(yan)室(shi)通(tong)(tong)风(feng)(feng)橱的(de)(de)原(yuan)理(li)-在(zai)(zai)实验(yan)(yan)室(shi)工作过程(cheng)中，大量(liang)有害气(qi)(qi)(qi)(qi)体通(tong)(tong)过实验(yan)(yan)室(shi)通(tong)(tong)风(feng)(feng)橱柜排(pai)(pai)出，也带走了大量(liang)的(de)(de)室(shi)内能(neng)(neng)量(liang)。为了减(jian)少能(neng)(neng)量(liang)损失，通(tong)(tong)风(feng)(feng)系统的(de)(de)设计应(ying)考虑排(pai)(pai)气(qi)(qi)(qi)(qi)能(neng)(neng)量(liang)回(hui)收(shou)。聚丙烯通(tong)(tong)风(feng)(feng)柜的(de)(de)能(neng)(neng)量(liang)回(hui)收(shou)方(fang)法有几(ji)种：1。板(ban)(ban)式空气(qi)(qi)(qi)(qi)热交(jiao)(jiao)换(huan)器(qi)用(yong)于交(jiao)(jiao)换(huan)板(ban)(ban)式交(jiao)(jiao)换(huan)器(qi)中废(fei)气(qi)(qi)(qi)(qi)和(he)(he)新鲜空气(qi)(qi)(qi)(qi)之间(jian)的(de)(de)能(neng)(neng)量(liang)。该系统相对(dui)简单，但(dan)设备(bei)体积大，占用(yong)房间(jian)面积大。2.一(yi)些实验(yan)(yan)设备(bei)在(zai)(zai)工作过程(cheng)中产生废(fei)气(qi)(qi)(qi)(qi)，设备(bei)本身配备(bei)了排(pai)(pai)气(qi)(qi)(qi)(qi)装置(zhi)(zhi)(zhi)。在(zai)(zai)通(tong)(tong)风(feng)(feng)设计中，应(ying)根据工艺要求在(zai)(zai)室(shi)内适(shi)当位置(zhi)(zhi)(zhi)设置(zhi)(zhi)(zhi)通(tong)(tong)向室(shi)外的(de)(de)垂(chui)直排(pai)(pai)气(qi)(qi)(qi)(qi)管(guan)。管(guan)道(dao)一(yi)般(ban)采(cai)用(yong)塑料管(guan)，可(ke)与排(pai)(pai)气(qi)(qi)(qi)(qi)装置(zhi)(zhi)(zhi)连(lian)接(jie)的(de)(de)接(jie)口和(he)(he)阀门设置(zhi)(zhi)(zhi)在(zai)(zai)排(pai)(pai)气(qi)(qi)(qi)(qi)立管(guan)的(de)(de)适(shi)当高(gao)度。3.中间(jian)介(jie)质(zhi)用(yong)于能(neng)(neng)源(yuan)回(hui)收(shou)。排(pai)(pai)气(qi)(qi)(qi)(qi)单元设置(zhi)(zhi)(zhi)线圈(quan)(quan)废(fei)热回(hui)收(shou)部分(fen)，空气(qi)(qi)(qi)(qi)供应(ying)单元设置(zhi)(zhi)(zhi)线圈(quan)(quan)新鲜空气(qi)(qi)(qi)(qi)预热部分(fen)。循环系统通(tong)(tong)过管(guan)道(dao)和(he)(he)水泵形成，废(fei)气(qi)(qi)(qi)(qi)中的(de)(de)能(neng)(neng)量(liang)通(tong)(tong)过中间(jian)介(jie)质(zhi)传(chuan)递给(ji)气(qi)(qi)(qi)(qi)源(yuan)。
