在塑(su)料(liao)制(zhi)品過程(cheng)中，電(dian)(dian)磁(ci)加(jia)(jia)(jia)熱器(qi)隨(sui)著功(gong)率(lv)(lv)調節(jie)旋轉開(kai)關，可以調節(jie)電(dian)(dian)磁(ci)感應加(jia)(jia)(jia)熱器(qi)的功(gong)率(lv)(lv)大小，當料(liao)簡溫度達到居(ju)里點時，電(dian)(dian)磁(ci)加(jia)(jia)(jia)熱控制(zhi)板自(zi)動(dong)斷(duan)電(dian)(dian)，可程(cheng)度減少能(neng)源(yuan)浪費。所以是不需要客戶自(zi)行(xing)去調節(jie)功(gong)率(lv)(lv)的，電(dian)(dian)磁(ci)加(jia)(jia)(jia)熱器(qi)系列產(chan)品，采用電(dian)(dian)磁(ci)加(jia)(jia)(jia)熱原理，具(ju)有安全、、節(jie)能(neng)、環保、省時、快捷、操作簡便等特點；是塑(su)料(liao)加(jia)(jia)(jia)熱行(xing)業的理想選擇。其(qi)特點如下：

電(dian)(dian)磁(ci)感(gan)應加(jia)(jia)(jia)(jia)熱(re)(re)(re)器(qi)與電(dian)(dian)磁(ci)加(jia)(jia)(jia)(jia)熱(re)(re)(re)器(qi)的(de)(de)區(qu)別？簡單(dan)的(de)(de)說，他們(men)實(shi)質上沒什么區(qu)別，都是(shi)(shi)(shi)電(dian)(dian)磁(ci)線圈(quan)發(fa)熱(re)(re)(re)盤而(er)已，并且加(jia)(jia)(jia)(jia)熱(re)(re)(re)的(de)(de)物質是(shi)(shi)(shi)有含鐵的(de)(de)物質。但是(shi)(shi)(shi)電(dian)(dian)磁(ci)感(gan)應加(jia)(jia)(jia)(jia)熱(re)(re)(re)器(qi)的(de)(de)加(jia)(jia)(jia)(jia)熱(re)(re)(re)原(yuan)理(li)是(shi)(shi)(shi)感(gan)應加(jia)(jia)(jia)(jia)熱(re)(re)(re)電(dian)(dian)源產生(sheng)的(de)(de)交變電(dian)(dian)流(liu)通(tong)過(guo)線圈(quan)而(er)產生(sheng)磁(ci)場(chang)，原(yuan)子相(xiang)互(hu)碰撞(zhuang)、摩擦而(er)產生(sheng)熱(re)(re)(re)能(neng)(neng)(neng)而(er)電(dian)(dian)磁(ci)加(jia)(jia)(jia)(jia)熱(re)(re)(re)器(qi)則(ze)是(shi)(shi)(shi)利用(yong)電(dian)(dian)磁(ci)感(gan)應加(jia)(jia)(jia)(jia)熱(re)(re)(re)器(qi)的(de)(de)原(yuan)理(li)將電(dian)(dian)能(neng)(neng)(neng)轉(zhuan)換為熱(re)(re)(re)能(neng)(neng)(neng)，將交流(liu)電(dian)(dian)壓轉(zhuan)換成直(zhi)流(liu)電(dian)(dian)壓，再經過(guo)控(kong)制電(dian)(dian)路將直(zhi)流(liu)電(dian)(dian)壓轉(zhuan)換為高頻電(dian)(dian)壓等系列轉(zhuan)換轉(zhuan)成磁(ci)場(chang)而(er)加(jia)(jia)(jia)(jia)熱(re)(re)(re)的(de)(de)方式。由于(yu)加(jia)(jia)(jia)(jia)熱(re)(re)(re)方式不樣，因此，操作(zuo)的(de)(de)方式也(ye)是(shi)(shi)(shi)不樣的(de)(de)。節(jie)能(neng)(neng)(neng)的(de)(de)效果電(dian)(dian)磁(ci)感(gan)應加(jia)(jia)(jia)(jia)熱(re)(re)(re)器(qi)會更好。

使用電(dian)磁加熱器時這幾點不(bu)可(ke)忽(hu)視：

1、電磁加熱器主機的安頓環(huan)境(jing)不能在-20℃以(yi)下(xia)，高也不能超過50℃，且要(yao)枯(ku)燥、通風(feng)。

2、接(jie)入電(dian)源前(qian)：清楚(chu)電(dian)器(qi)作業需要(yao)(yao)的(de)(de)(de)總(zong)電(dian)量和(he)供(gong)電(dian)變(bian)壓器(qi)的(de)(de)(de)總(zong)容量，不(bu)能(neng)超過供(gong)電(dian)的(de)(de)(de)總(zong)容量，也盡可能(neng)不(bu)要(yao)(yao)去糟(zao)蹋。別的(de)(de)(de)要(yao)(yao)辨明(ming)單相220v、三(san)相380v電(dian)壓，不(bu)能(neng)接(jie)錯(cuo)。終要(yao)(yao)留意的(de)(de)(de)就是，當(dang)電(dian)網的(de)(de)(de)電(dian)壓在規則電(dian)壓規模的(de)(de)(de)上下10%起(qi)浮時(shi)，制止運用大功率電(dian)磁(ci)加熱設備。

3、變(bian)頻(pin)電(dian)磁加(jia)熱器(qi)是怕水(shui)的，因(yin)而、總歸，電(dian)磁加(jia)熱器(qi)不能有水(shui)進(jin)入，任何狀況下(xia)都要防止這狀況，水(shui)蒸汽、濕氣過重(zhong)也不可，電(dian)磁加(jia)熱線(xian)也相同怕水(shui)，切忌用濕潤的手去(qu)觸摸或是在電(dian)磁加(jia)熱線(xian)上搭曬濕潤的衣(yi)物等等。

4、電(dian)(dian)(dian)磁(ci)加(jia)熱器生產(chan)廠家印刷電(dian)(dian)(dian)路板周圍(wei)不(bu)(bu)能(neng)有塑料、乙烯基和聚苯(ben)乙烯泡沫塑料(抗靜(jing)電(dian)(dian)(dian)類(lei)型在外(wai))，靜(jing)電(dian)(dian)(dian)很可能(neng)會(hui)損壞這些(xie)電(dian)(dian)(dian)路。不(bu)(bu)要觸摸操控接口板或(huo)操控板的IC電(dian)(dian)(dian)路。

5、電(dian)磁(ci)加熱線外表是石棉原料，怕磨，因而電(dian)磁(ci)加熱線應(ying)防止轟動兇猛的(de)設(she)備，防止磨損的(de)電(dian)磁(ci)加熱線呈現(xian)漏(lou)電(dian)現(xian)象，觸(chu)摸(mo)(mo)接地的(de)金屬物(wu)體，用手觸(chu)摸(mo)(mo)這(zhe)些操控(kong)器之前消除身體上的(de)靜電(dian)(封閉操控(kong)器的(de)電(dian)源。并且在(zai)觸(chu)摸(mo)(mo)操控(kong)器時(shi)堅持(chi)接地)。

6、任(ren)何替換設備、檢修設備環節定要斷(duan)電今后才干進行(xing)，不(bu)要用手或導體(ti)(ti)觸摸印刷電路(lu)板上(shang)的元件或導體(ti)(ti)。

7、任何(he)替(ti)換設備、檢修設備環節(jie)定要(yao)斷電今后才干進行。

電(dian)磁式加(jia)熱(re)方(fang)式與電(dian)阻(zu)絲加(jia)熱(re)方(fang)式對比：

1、節能(neng)效(xiao)果(guo)好：相(xiang)(xiang)比(bi)原電(dian)阻絲加熱圈(quan)節電(dian)效(xiao)果(guo)都在30%以上，相(xiang)(xiang)對不同(tong)的原料、生產(chan)不同(tong)的產(chan)品(pin)，節電(dian)效(xiao)果(guo)有所變(bian)化(hua)。但在已使用的產(chan)品(pin)中節電(dian)效(xiao)率大(da)可達75%。

2、環(huan)保(bao)效果好：可顯(xian)著降(jiang)低(di)環(huan)境溫度(du)。

3、使用壽命長：加(jia)熱圈連(lian)續運行(xing)溫度只有100℃左(zuo)右，不存在加(jia)熱圈更換問題。相對于(yu)電阻絲(si)加(jia)熱減少了二次投入。

4、可提高產(chan)(chan)品(pin)產(chan)(chan)量(liang)：由于該產(chan)(chan)品(pin)的(de)發熱(re)效率(lv)高，能顯著減少升(sheng)溫時間(jian)，提高產(chan)(chan)品(pin)產(chan)(chan)量(liang)。

5、性能(neng)安(an)全可靠：品質(zhi)優良、高度(du)自動化、無須人工調節。

電磁加(jia)熱技術(shu)原理(li)：

1、電(dian)(dian)(dian)(dian)磁加(jia)熱(re)器(qi)：電(dian)(dian)(dian)(dian)磁加(jia)熱(re)器(qi)是(shi)種利用電(dian)(dian)(dian)(dian)磁感應原理將電(dian)(dian)(dian)(dian)能轉化(hua)成(cheng)熱(re)能的(de)裝置，電(dian)(dian)(dian)(dian)磁加(jia)熱(re)控制器(qi)將220V，50/60HZ的(de)交(jiao)(jiao)流(liu)電(dian)(dian)(dian)(dian)整流(liu)變成(cheng)直流(liu)電(dian)(dian)(dian)(dian)，再(zai)將直流(liu)電(dian)(dian)(dian)(dian)轉成(cheng)頻率為20-40KHZ的(de)高(gao)頻高(gao)壓(ya)電(dian)(dian)(dian)(dian)，或者是(shi)380v 50/60HZ的(de)三相交(jiao)(jiao)流(liu)電(dian)(dian)(dian)(dian)轉換成(cheng)直流(liu)電(dian)(dian)(dian)(dian)再(zai)將直流(liu)電(dian)(dian)(dian)(dian)轉換成(cheng)10~30KHZ的(de)高(gao)頻低壓(ya)大電(dian)(dian)(dian)(dian)流(liu)電(dian)(dian)(dian)(dian)，用來工業產(chan)品(pin)加(jia)熱(re)。

2、電(dian)磁(ci)加(jia)(jia)熱(re)(re)圈(quan)：高(gao)速變(bian)化(hua)的高(gao)頻(pin)高(gao)壓電(dian)流(liu)流(liu)過線圈(quan)會產生(sheng)(sheng)高(gao)速變(bian)化(hua)的交變(bian)磁(ci)場，當(dang)用(yong)含鐵質(zhi)容器(qi)放置上面(mian)時，容器(qi)表(biao)面(mian)即(ji)具切割(ge)交變(bian)磁(ci)力線而在容器(qi)底部(bu)(bu)金(jin)屬部(bu)(bu)分產生(sheng)(sheng)交變(bian)的電(dian)流(liu)（即(ji)渦(wo)流(liu)），渦(wo)流(liu)使(shi)容器(qi)底部(bu)(bu)的載流(liu)子高(gao)速無規則運動，載流(liu)子互(hu)相(xiang)碰撞(zhuang)、摩擦而產生(sheng)(sheng)熱(re)(re)能(neng)(neng)。從而起到(dao)加(jia)(jia)熱(re)(re)物(wu)品的效果。即(ji)是通(tong)過把(ba)電(dian)能(neng)(neng)轉(zhuan)化(hua)為磁(ci)能(neng)(neng)，使(shi)被加(jia)(jia)熱(re)(re)鋼體(ti)表(biao)面(mian)產生(sheng)(sheng)感應渦(wo)流(liu)種(zhong)加(jia)(jia)熱(re)(re)方(fang)式(shi)(shi)(shi)。這種(zhong)方(fang)式(shi)(shi)(shi)從根本上解決了電(dian)熱(re)(re)片、電(dian)熱(re)(re)圈(quan)等(deng)電(dian)阻式(shi)(shi)(shi)的，通(tong)過熱(re)(re)傳(chuan)導方(fang)式(shi)(shi)(shi)加(jia)(jia)熱(re)(re)產生(sheng)(sheng)的熱(re)(re)效率低下的問題。

如何選擇電(dian)磁加熱器保(bao)溫(wen)材料？

1、根據材料的耐溫(wen)(wen)等，選(xuan)擇耐溫(wen)(wen)比(bi)發熱(re)體表(biao)面的加(jia)熱(re)溫(wen)(wen)度(du)高至少300度(du)的保溫(wen)(wen)材料。

2、根(gen)據電磁加(jia)熱控制器線(xian)圈(quan)布置的面(mian)積以及線(xian)圈(quan)與發熱體(ti)的距離，選擇合(he)適(shi)導熱系數的保(bao)溫(wen)材(cai)料(liao)。

3、根據線(xian)圈(quan)成型要求，選擇(ze)不同致密性和(he)硬度的保(bao)溫材料。

4、根(gen)據現(xian)場的施工條件，選擇適合(he)的保溫材料。

5、重要的條原則，就(jiu)是要保(bao)證(zheng)經(jing)過上述選擇后，保(bao)溫(wen)棉表面(mian)的溫(wen)度在工作過程中，盡可(ke)能低(di)。高(gao)溫(wen)場合至少要保(bao)持在100度以下。
