塑(su)料(liao)(liao)作為一種(zhong)新型材料(liao)(liao)，在人類(lei)的生活中(zhong)得(de)到(dao)了廣泛利用(yong)，已涉(she)及(ji)生活各個領(ling)域。然而，人們使(shi)用(yong)過的塑(su)料(liao)(liao)制(zhi)品等廢(fei)棄之后，會變成(cheng)危害人類(lei)健康的“白色垃圾”。僅以塑(su)料(liao)(liao)農地(di)膜(mo)為例:由(you)于地(di)膜(mo)是一種(zhong)高分子的碳氫化合物，外墻保溫板再生造粒(li)機生產廠家，在自然條件下難以降解，當土壤(rang)中(zhong)殘留地(di)膜(mo)達到(dao)一定數量時(shi)，形成(cheng)阻隔層。造粒(li)主(zhu)機也稱造粒(li)主(zhu)機（母機），其(qi)特點是，不(bu)同(tong)(tong)塑(su)料(liao)(liao)的造粒(li)機其(qi)主(zhu)要區別體(ti)現(xian)在主(zhu)機上，通過其(qi)螺桿設計與變化，配(pei)置參數變化，以達到(dao)生產不(bu)同(tong)(tong)塑(su)料(liao)(liao)顆(ke)粒(li)的要求。

   造(zao)粒(li)機(ji)的加熱(re)溫(wen)(wen)(wen)(wen)(wen)度(du)(du)(du)(du)取決于(yu)載(zai)體(ti)樹(shu)脂(zhi)的軟(ruan)(ruan)化點或(huo)熔(rong)(rong)融溫(wen)(wen)(wen)(wen)(wen)度(du)(du)(du)(du)，外墻保(bao)溫(wen)(wen)(wen)(wen)(wen)板(ban)再生造(zao)粒(li)機(ji)報(bao)價，載(zai)體(ti)樹(shu)脂(zhi)軟(ruan)(ruan)化點或(huo)熔(rong)(rong)融溫(wen)(wen)(wen)(wen)(wen)度(du)(du)(du)(du)越高，加熱(re)溫(wen)(wen)(wen)(wen)(wen)度(du)(du)(du)(du)也就越高，一般應(ying)高出樹(shu)脂(zhi)的熔(rong)(rong)融溫(wen)(wen)(wen)(wen)(wen)度(du)(du)(du)(du)5℃左右。加熱(re)溫(wen)(wen)(wen)(wen)(wen)度(du)(du)(du)(du)過低(di)樹(shu)脂(zhi)不能充分熔(rong)(rong)化，有限的載(zai)體(ti)樹(shu)脂(zhi)也就無(wu)法將無(wu)機(ji)粉(fen)完全包覆，母(mu)粒(li)的表面(mian)粗糙(cao)粒(li)子(zi)中(zhong)間(jian)出現空洞，蘇(su)州(zhou)外墻保(bao)溫(wen)(wen)(wen)(wen)(wen)板(ban)再生造(zao)粒(li)機(ji)，樹(shu)脂(zhi)和無(wu)機(ji)粉(fen)體(ti)無(wu)法成(cheng)均勻(yun)體(ti)系。加熱(re)溫(wen)(wen)(wen)(wen)(wen)度(du)(du)(du)(du)過高，助劑易揮(hui)發(fa)樣，螺桿(gan)剪切力降(jiang)低(di)不宜塑化，同樣影響母(mu)粒(li)的質(zhi)量。一般情況下，二區(qu)(qu)溫(wen)(wen)(wen)(wen)(wen)度(du)(du)(du)(du)應(ying)是造(zao)粒(li)溫(wen)(wen)(wen)(wen)(wen)度(du)(du)(du)(du)，一區(qu)(qu)比二區(qu)(qu)溫(wen)(wen)(wen)(wen)(wen)度(du)(du)(du)(du)低(di)10℃左右，三(san)區(qu)(qu)、四區(qu)(qu)溫(wen)(wen)(wen)(wen)(wen)度(du)(du)(du)(du)與二區(qu)(qu)基本(ben)相同，外墻保(bao)溫(wen)(wen)(wen)(wen)(wen)板(ban)再生造(zao)粒(li)機(ji)廠家，從(cong)五區(qu)(qu)開始直(zhi)至(zhi)機(ji)頭按5~10℃的梯度(du)(du)(du)(du)逐漸降(jiang)低(di)。

高(gao)頻(pin)(pin)感應加熱裝置主要用于(yu)塑料制造業。在成熟的(de)”交-直-交”變(bian)頻(pin)(pin)技術(shu)基礎上，結合工(gong)業自動化(hua)儀表(biao)與(yu)控制技術(shu)以及優化(hua)PID算(suan)法(fa)，實現(xian)了變(bian)電感量(liang)和(he)變(bian)風(feng)量(liang)、諧波抑制、電磁屏蔽、循環水均勻(yun)冷卻自動控制等技術(shu)目標。該裝置采用了的(de)工(gong)藝設計，安裝穩(wen)定，確保(bao)了設備和(he)生產的(de)安全、穩(wen)定、環保(bao)、節(jie)能(neng)，滿足了塑料加工(gong)生產線(xian)節(jie)能(neng)減排及環保(bao)的(de)要求(qiu)。
