吹塑加工過程中,在模具成型(xing)的時(shi)分需求進步熱(re)量的運用(yong)(yong)率,而(er)在成型(xing)冷(leng)(leng)(leng)(leng)卻(que)的時(shi)分,則(ze)需求較快的下(xia)降(jiang)溫度,一般冷(leng)(leng)(leng)(leng)卻(que)選用(yong)(yong)的介質(zhi)是水(shui)(shui)(shui),水(shui)(shui)(shui)價格低(di),成本自然(ran)也就低(di),冷(leng)(leng)(leng)(leng)卻(que)往后的水(shui)(shui)(shui)源(yuan)能夠循環運用(yong)(yong)。低(di)價格與(yu)可循選使得(de)其(qi)只能作(zuo)為初級(ji)冷(leng)(leng)(leng)(leng)卻(que)劑來運用(yong)(yong),如果想(xiang)要達(da)到冷(leng)(leng)(leng)(leng)卻(que)作(zuo)用(yong)(yong)仍(reng)是需求運用(yong)(yong)冷(leng)(leng)(leng)(leng)模,并且(qie)冷(leng)(leng)(leng)(leng)卻(que)劑并不是越(yue)冷(leng)(leng)(leng)(leng)越(yue)好,物極必反(fan)(fan),過冷(leng)(leng)(leng)(leng)可能會(hui)呈(cheng)現反(fan)(fan)作(zuo)用(yong)(yong)。
