磁力加熱攪拌器是(shi)用于(yu)液(ye)(ye)體(ti)混合的(de)(de)實驗室儀器(qi)，主(zhu)要用于(yu)攪(jiao)(jiao)拌(ban)或同時(shi)加熱攪(jiao)(jiao)拌(ban)低粘稠度(du)的(de)(de)液(ye)(ye)體(ti)或固液(ye)(ye)混合物。其(qi)基本原理是(shi)利用磁(ci)場的(de)(de)同性相斥(chi)、異性相吸的(de)(de)原理，使(shi)用磁(ci)場推動放置在(zai)容(rong)器(qi)中帶(dai)磁(ci)性的(de)(de)攪(jiao)(jiao)拌(ban)子進行圓(yuan)周(zhou)運(yun)轉，從而達到攪(jiao)(jiao)拌(ban)液(ye)(ye)體(ti)的(de)(de)目的(de)(de)。下面我們聊(liao)聊(liao)磁(ci)力加熱攪(jiao)(jiao)拌(ban)器(qi)的(de)(de)溫度(du)控制方式(shi)和溫度(du)控制措施。
磁力攪拌器溫度控制方式通常(chang)有兩種:
1、一(yi)種是(shi)電(dian)(dian)接觸汞(gong)JiKong溫(wen)(wen)(wen)(wen)(wen)(wen)度(du)(du)，另一(yi)種是(shi)通(tong)過控(kong)制溫(wen)(wen)(wen)(wen)(wen)(wen)度(du)(du)傳感(gan)器(電(dian)(dian)動),接觸汞(gong)和電(dian)(dian)力在使用過程(cheng)中傳感(gan)器的(de)一(yi)端進(jin)入測量液體(ti),另一(yi)端連接到(dao)機器上,在這個過程(cheng)中當液體(ti)溫(wen)(wen)(wen)(wen)(wen)(wen)度(du)(du)低(di)于(yu)設(she)置溫(wen)(wen)(wen)(wen)(wen)(wen)度(du)(du),加(jia)(jia)溫(wen)(wen)(wen)(wen)(wen)(wen)板(ban)會加(jia)(jia)熱(re),當溫(wen)(wen)(wen)(wen)(wen)(wen)度(du)(du)達到(dao)設(she)置溫(wen)(wen)(wen)(wen)(wen)(wen)度(du)(du)的(de)液體(ti),然后由(you)電(dian)(dian)點水(shui)銀溫(wen)(wen)(wen)(wen)(wen)(wen)度(du)(du)計或(huo)傳感(gan)器信號到(dao)主機磁攪拌器，加(jia)(jia)溫(wen)(wen)(wen)(wen)(wen)(wen)板(ban)會停止加(jia)(jia)熱(re),再當溫(wen)(wen)(wen)(wen)(wen)(wen)度(du)(du)低(di)于(yu)設(she)置溫(wen)(wen)(wen)(wen)(wen)(wen)度(du)(du),加(jia)(jia)溫(wen)(wen)(wen)(wen)(wen)(wen)板(ban)的(de)繼續加(jia)(jia)溫(wen)(wen)(wen)(wen)(wen)(wen),這是(shi)磁性(xing)的(de)原理，混合器溫(wen)(wen)(wen)(wen)(wen)(wen)度(du)(du)控(kong)制。
2、磁力攪拌器(qi)溫(wen)(wen)(wen)(wen)(wen)(wen)度(du)(du)控(kong)(kong)制措施(shi): 先，加(jia)溫(wen)(wen)(wen)(wen)(wen)(wen)板(ban)有一(yi)個(ge)熱慣性,溫(wen)(wen)(wen)(wen)(wen)(wen)度(du)(du)控(kong)(kong)制可能高于(yu)設(she)置溫(wen)(wen)(wen)(wen)(wen)(wen)度(du)(du),若要求較(jiao)高,要注意(yi)控(kong)(kong)制溫(wen)(wen)(wen)(wen)(wen)(wen)度(du)(du)的加(jia)溫(wen)(wen)(wen)(wen)(wen)(wen)板(ban)(即加(jia)溫(wen)(wen)(wen)(wen)(wen)(wen)電壓)。 第二,使用電接觸汞溫(wen)(wen)(wen)(wen)(wen)(wen)度(du)(du),當溫(wen)(wen)(wen)(wen)(wen)(wen)度(du)(du)高于(yu)電點水銀溫(wen)(wen)(wen)(wen)(wen)(wen)度(du)(du)計設(she)置溫(wen)(wen)(wen)(wen)(wen)(wen)度(du)(du),傳(chuan)感(gan)器(qi)溫(wen)(wen)(wen)(wen)(wen)(wen)度(du)(du)控(kong)(kong)制方法是在主機上設(she)置溫(wen)(wen)(wen)(wen)(wen)(wen)度(du)(du)，因此(ci),溫(wen)(wen)(wen)(wen)(wen)(wen)度(du)(du)控(kong)(kong)制傳(chuan)感(gan)器(qi)更方便。但(dan)傳(chuan)感(gan)器(qi)采用金(jin)屬材(cai)料，要注意(yi)防腐蝕。
磁力攪(jiao)拌器使(shi)用注(zhu)意(yi)事項(xiang)：
1、磁力攪(jiao)拌(ban)器使用前地線要妥善接地。
2、磁力攪拌(ban)器在運轉(zhuan)(zhuan)時要把(ba)轉(zhuan)(zhuan)速(su)旋鈕(niu)調(diao)到小，連接電源(yuan)并逐(zhu)漸調(diao)到合適的速(su)度，加(jia)速(su)太快會使攪拌(ban)轉(zhuan)(zhuan)子不停(ting)跳躍，此時要立刻把(ba)轉(zhuan)(zhuan)速(su)調(diao)回(hui)“低位(wei)”，待轉(zhuan)(zhuan)子停(ting)止(zhi)跳動后再緩慢(man)加(jia)速(su)。
3、間歇使(shi)用(yong)磁力攪拌器(qi)(qi)能夠延長儀器(qi)(qi)的使(shi)用(yong)壽命。
4、連(lian)續(xu)工(gong)作(zuo)時(shi)間若超過2小時(shi)，請用低速(su)攪拌，這樣(yang)可連(lian)續(xu)工(gong)作(zuo)4-8h以上。
5、工作時請(qing)把容器放(fang)置在(zai)金屬托盤上(shang)合適位置，以便攪拌(ban)槳在(zai)旋(xuan)轉時不會碰到容器壁，否則攪拌(ban)會忽(hu)快忽(hu)慢影(ying)響(xiang)到攪拌(ban)效果。當液(ye)體灑在(zai)托盤上(shang)時，要立即斷電清除，防止(zhi)腐蝕或影(ying)響(xiang)電熱元(yuan)件，阻礙(ai)電機正常(chang)工作。
6、測定(ding)時應使電(dian)對在攪(jiao)拌(ban)轉子上方一定(ding)距(ju)離(li)處(chu)，避免(mian)二(er)者發生碰撞(zhuang)而損壞電(dian)。
7、請保持容器外壁干燥。
8、磁力攪拌器停止工(gong)作時請及時切斷電源。
