通(tong)風柜(ju)在實驗(yan)室中的使用注意(yi)事(shi)項

通風柜是實驗室常用的局部排風設施，是實驗室環境中重要的裝置。功能強、種類多、適用范圍廣、通風作用好。目前比較常用的通風柜有臺式和落地式兩種，實驗室根據需要配備。南寧凈化工程

通(tong)(tong)(tong)(tong)(tong)風(feng)(feng)(feng)(feng)(feng)柜(ju)(ju)只有(you)在(zai)(zai)使用得當的(de)情況下(xia)才能提(ti)供(gong)有(you)效(xiao)的(de)保(bao)護，所以(yi)(yi)正確的(de)使用很重要。通(tong)(tong)(tong)(tong)(tong)風(feng)(feng)(feng)(feng)(feng)柜(ju)(ju)具有(you)高度(du)可變的(de)通(tong)(tong)(tong)(tong)(tong)風(feng)(feng)(feng)(feng)(feng)量，并配備輕空氣(qi)(qi)、中空氣(qi)(qi)和(he)重空氣(qi)(qi)通(tong)(tong)(tong)(tong)(tong)風(feng)(feng)(feng)(feng)(feng)口(kou)和(he)擋板(ban)(ban)。輕型通(tong)(tong)(tong)(tong)(tong)風(feng)(feng)(feng)(feng)(feng)口(kou)位(wei)于(yu)(yu)(yu)通(tong)(tong)(tong)(tong)(tong)風(feng)(feng)(feng)(feng)(feng)柜(ju)(ju)頂部，中型通(tong)(tong)(tong)(tong)(tong)風(feng)(feng)(feng)(feng)(feng)口(kou)位(wei)于(yu)(yu)(yu)導(dao)(dao)流(liu)(liu)板(ban)(ban)中間(jian)，重型通(tong)(tong)(tong)(tong)(tong)風(feng)(feng)(feng)(feng)(feng)口(kou)位(wei)于(yu)(yu)(yu)導(dao)(dao)流(liu)(liu)板(ban)(ban)下(xia)部與工(gong)(gong)作(zuo)臺面之間(jian)，由來自進口(kou)的(de)氣(qi)(qi)流(liu)(liu)驅動(dong)。移動(dong)玻(bo)璃(li)門功能，有(you)害氣(qi)(qi)體(ti)在(zai)(zai)導(dao)(dao)流(liu)(liu)板(ban)(ban)內強制(zhi)排(pai)出，在(zai)(zai)導(dao)(dao)流(liu)(liu)板(ban)(ban)內進行(xing)加(jia)速排(pai)放(fang)。通(tong)(tong)(tong)(tong)(tong)風(feng)(feng)(feng)(feng)(feng)柜(ju)(ju)送(song)風(feng)(feng)(feng)(feng)(feng)口(kou)位(wei)于(yu)(yu)(yu)前擋板(ban)(ban)上(shang)，可在(zai)(zai)活動(dong)門全關時提(ti)供(gong)送(song)風(feng)(feng)(feng)(feng)(feng)。導(dao)(dao)槽(cao)設置在(zai)(zai)背板(ban)(ban)與導(dao)(dao)板(ban)(ban)中間(jian)層之間(jian)，通(tong)(tong)(tong)(tong)(tong)風(feng)(feng)(feng)(feng)(feng)柜(ju)(ju)內的(de)有(you)毒氣(qi)(qi)體(ti)排(pai)入導(dao)(dao)槽(cao)后(hou)，提(ti)高風(feng)(feng)(feng)(feng)(feng)速。通(tong)(tong)(tong)(tong)(tong)風(feng)(feng)(feng)(feng)(feng)柜(ju)(ju)頂部、底部和(he)擋板(ban)(ban)后(hou)面的(de)槽(cao)用于(yu)(yu)(yu)排(pai)放(fang)污(wu)染(ran)氣(qi)(qi)體(ti)。這些狹縫通(tong)(tong)(tong)(tong)(tong)道必須時刻保(bao)持一定的(de)屏障(zhang)，以(yi)(yi)利(li)于(yu)(yu)(yu)污(wu)染(ran)氣(qi)(qi)體(ti)的(de)排(pai)放(fang)。工(gong)(gong)作(zuo)時，盡量關閉通(tong)(tong)(tong)(tong)(tong)風(feng)(feng)(feng)(feng)(feng)柜(ju)(ju)并移動(dong)玻(bo)璃(li)窗，以(yi)(yi)防止柜(ju)(ju)內的(de)污(wu)染(ran)空氣(qi)(qi)流(liu)(liu)出通(tong)(tong)(tong)(tong)(tong)風(feng)(feng)(feng)(feng)(feng)柜(ju)(ju)，污(wu)染(ran)實驗室空氣(qi)(qi)。通(tong)(tong)(tong)(tong)(tong)風(feng)(feng)(feng)(feng)(feng)柜(ju)(ju)的(de)表面風(feng)(feng)(feng)(feng)(feng)速一般為(wei)0.5～1.0m/s。如果風(feng)(feng)(feng)(feng)(feng)速太低，作(zuo)用就不好。風(feng)(feng)(feng)(feng)(feng)速過大會(hui)擾亂氣(qi)(qi)流(liu)(liu)，影響正常通(tong)(tong)(tong)(tong)(tong)風(feng)(feng)(feng)(feng)(feng)作(zuo)用。

預防(fang)措施：

1、不要(yao)將化學反(fan)應(ying)長期留(liu)在通風柜(ju)中無人看管(guan)，所有有害物質建議用標簽清晰準(zhun)確(que)的標識。

2、不要(yao)在通風柜內同(tong)時(shi)放置儀器和可引起電火花的易燃(ran)化學品，插(cha)座(zuo)應安裝在滑(hua)動玻(bo)璃門外。

3、通(tong)風(feng)(feng)柜(ju)(ju)(ju)不(bu)是(shi)儲物柜(ju)(ju)(ju)。堆放(fang)物品(pin)會減(jian)少空氣流通(tong)，通(tong)風(feng)(feng)柜(ju)(ju)(ju)排(pai)風(feng)(feng)效率下(xia)降。通(tong)風(feng)(feng)柜(ju)(ju)(ju)內(nei)的工(gong)作區域(yu)應保持清潔，危險化學品(pin)不(bu)應長期存放(fang)在通(tong)風(feng)(feng)柜(ju)(ju)(ju)內(nei)。揮發(fa)性(xing)試劑應存放(fang)在專門通(tong)風(feng)(feng)的儲存柜(ju)(ju)(ju)中(zhong)，危險化學品(pin)建議存放(fang)在經批準(zhun)的保護柜(ju)(ju)(ju)中(zhong)。

4、工作過程(cheng)中不要(yao)把頭放在通風柜里。對于有爆(bao)炸(zha)或爆(bao)炸(zha)可能性(xing)的(de)實驗，必須在柜門上安裝合適(shi)的(de)屏蔽(bi)。在實驗過程(cheng)中，研究人(ren)員必須始終佩(pei)戴合適(shi)的(de)個(ge)人(ren)防護裝備。
