使用木飾墻面裝飾板機器代加工
安(an)徽(hui)嘉好機械制造有限公司,深(shen)耕(geng)于塑料擠出行業,對(dui)塑料制品的生產工藝有確定(ding)的標準。那么PVC木飾(shi)面板在塑料擠出機內(nei)塑化效果的評定(ding)應遵循(xun)什么樣的標準呢:
擠出生產后與和模(mo)前,牽(qian)引板(ban)(ban)坯塊定型(xing)板(ban)(ban)出來后用手(shou)彈壓(ya)板(ban)(ban)面,如果壓(ya)坑能立即(ji)反彈,壓(ya)坑消失快,說(shuo)明(ming)板(ban)(ban)坯塑化良好,板(ban)(ban)體強度高。
如果板(ban)坯經彈壓(ya)后,壓(ya)坑長時間不消失或消失緩(huan)慢,說明板(ban)坯塑化較差(cha),強度較低。
操作者(zhe)可以根據生產中的(de)實際情況,決定是否需要延長恒溫(wen)時間,還是降低(di)設(she)定溫(wen)度(du),待熔體溫(wen)度(du)下降后,在實施牽引。保證物料在良(liang)好是塑(su)化狀態下開機(ji)。微發泡的(de)木飾面(mian)板,具有(you)成本低(di),密度(du)小,對設(she)備磨(mo)損小,無污染和可降解等特點。使用(yong)木飾墻面(mian)裝飾板機(ji)器(qi)代加工
木飾面板生產(chan)需(xu)要的(de)塑料擠出機(ji),需(xu)要專業的(de)技(ji)能(neng)操作,而機(ji)筒(tong)螺桿是塑料擠出機(ji)中的(de)重要組成(cheng)部分,也是很容易被磨(mo)損(sun)的(de)部分。
接下來(lai)我們(men)從原料(liao)中含有雜質,擠出(chu)機空載運行,非計劃停電等方面來(lai)討(tao)論對(dui)機筒螺桿(gan)的影響。
1.原(yuan)料(liao)中(zhong)(zhong)含有(you)雜(za)質若(ruo)原(yuan)料(liao)中(zhong)(zhong)混(hun)雜(za)有(you)下腳料(liao),金屬(shu)微粒等(deng)雜(za)質,或(huo)是在(zai)(zai)停產期間(jian)不進行有(you)效防護或(huo)操(cao)作(zuo),檢修人(ren)員不慎導(dao)致鐵釘(ding)等(deng)異物(wu)墜入料(liao)斗中(zhong)(zhong),直(zhi)接(jie)進入擠(ji)(ji)出(chu)機(ji)(ji),會(hui)(hui)對機(ji)(ji)筒(tong)螺(luo)(luo)(luo)桿(gan)造成損傷。2.擠(ji)(ji)出(chu)機(ji)(ji)空(kong)載(zai)(zai)運(yun)行錐(zhui)形雙螺(luo)(luo)(luo)桿(gan)在(zai)(zai)擠(ji)(ji)出(chu)機(ji)(ji)內,大頭(tou)在(zai)(zai)機(ji)(ji)筒(tong)中(zhong)(zhong)是依靠扭矩(ju)分配器(qi)軸(zhou)承(cheng)支撐的,而小(xiao)頭(tou)在(zai)(zai)機(ji)(ji)筒(tong)內則處(chu)于懸臂狀態。在(zai)(zai)擠(ji)(ji)出(chu)時(shi)(shi)通過物(wu)料(liao)充盈其間(jian),避免螺(luo)(luo)(luo)桿(gan)和機(ji)(ji)筒(tong)直(zhi)接(jie)接(jie)觸,摩擦。如果在(zai)(zai)擠(ji)(ji)出(chu)機(ji)(ji)開(kai)機(ji)(ji)時(shi)(shi),機(ji)(ji)筒(tong)內沒有(you)添加混(hun)合料(liao)或(huo)者清洗料(liao)空(kong)載(zai)(zai)運(yun)行,螺(luo)(luo)(luo)桿(gan)就會(hui)(hui)直(zhi)接(jie)和機(ji)(ji)筒(tong)接(jie)觸,摩擦,會(hui)(hui)導(dao)致機(ji)(ji)筒(tong)螺(luo)(luo)(luo)桿(gan)的磨(mo)損。3.非計劃停電若(ruo)擠(ji)(ji)出(chu)機(ji)(ji)在(zai)(zai)正常(chang)運(yun)行中(zhong)(zhong)突然(ran)停電,機(ji)(ji)筒(tong)內物(wu)料(liao)不能(neng)及時(shi)(shi)擠(ji)(ji)出(chu),較長時(shi)(shi)間(jian)停留在(zai)(zai)擠(ji)(ji)出(chu)機(ji)(ji)內。不僅會(hui)(hui)對機(ji)(ji)筒(tong)螺(luo)(luo)(luo)桿(gan)造成銹(xiu)蝕(shi),屋里哦啊也極可能(neng)在(zai)(zai)長時(shi)(shi)間(jian)高溫情(qing)況下發(fa)生(sheng)局部(bu)分解,當擠(ji)(ji)出(chu)機(ji)(ji)再次(ci)升溫時(shi)(shi),形成積碳(tan),影響制品質量。遼寧木飾(shi)墻(qiang)面裝飾(shi)板(ban)機(ji)(ji)器(qi)功率木飾(shi)墻(qiang)面裝飾(shi)板(ban),墻(qiang)面快裝板(ban)。

木(mu)飾(shi)面板生產需(xu)要(yao)的(de)塑(su)料(liao)擠出機(ji),需(xu)要(yao)專業(ye)的(de)技能操作,而機(ji)筒螺桿是塑(su)料(liao)擠出機(ji)中的(de)重要(yao)組成部分,也是很容(rong)易(yi)被磨損的(de)部分。
接下(xia)來(lai)我們從低溫或高溫工作(zuo),開(kai)機(ji)頻(pin)率(lv)來(lai)討論對(dui)機(ji)筒螺桿的(de)影響。
低溫(wen)(wen)或(huo)高溫(wen)(wen)工作擠(ji)(ji)(ji)出(chu)(chu)機(ji)(ji)開機(ji)(ji)前應(ying)進行升溫(wen)(wen)和(he)恒溫(wen)(wen)。如果(guo)升溫(wen)(wen),恒溫(wen)(wen)溫(wen)(wen)度(du)及(ji)時間達不(bu)到技術規范要求,或(huo)者在低溫(wen)(wen)條件下開機(ji)(ji),不(bu)僅因(yin)物(wu)流塑化(hua)不(bu)好(hao)影響(xiang)制品質(zhi)量(liang),也(ye)會(hui)因(yin)為物(wu)料過生,扭矩跑(pao)高,導致擠(ji)(ji)(ji)出(chu)(chu)機(ji)(ji)機(ji)(ji)械損(sun)(sun)壞與(yu)磨損(sun)(sun),反之(zhi)如果(guo)擠(ji)(ji)(ji)出(chu)(chu)機(ji)(ji)物(wu)料溫(wen)(wen)度(du),熔壓偏高不(bu)及(ji)時處理,擠(ji)(ji)(ji)出(chu)(chu)機(ji)(ji)螺桿與(yu)機(ji)(ji)筒(tong)材質(zhi)會(hui)因(yin)溫(wen)(wen)度(du)與(yu)承(cheng)壓過高發生蠕(ru)變,抗摩擦性(xing)能降低,加劇擠(ji)(ji)(ji)出(chu)(chu)機(ji)(ji)磨損(sun)(sun),物(wu)料局(ju)部分解,形成積碳,影響(xiang)制品質(zhi)量(liang)。5.開機(ji)(ji)頻率由(you)于每次(ci)開機(ji)(ji)都(dou)不(bu)能保證擠(ji)(ji)(ji)出(chu)(chu)機(ji)(ji)螺桿和(he)機(ji)(ji)筒(tong)間充滿物(wu)料,尤其是長(chang)期停運的(de)擠(ji)(ji)(ji)出(chu)(chu)機(ji)(ji)。每開一(yi)次(ci)擠(ji)(ji)(ji)出(chu)(chu)機(ji)(ji)都(dou)有可能加劇擠(ji)(ji)(ji)出(chu)(chu)機(ji)(ji)螺桿和(he)機(ji)(ji)筒(tong)之(zhi)前的(de)磨損(sun)(sun)。間斷開停機(ji)(ji)與(yu)長(chang)周期運行擠(ji)(ji)(ji)出(chu)(chu)機(ji)(ji)相比,使(shi)用壽命會(hui)減少很多(duo)。木飾面(mian)板不(bu)易(yi)開裂,不(bu)怕蟲蛀,很耐用。
木飾面板(ban)生產,首(shou)先應有良好(hao)塑(su)化,穩定劑加量是(shi)否(fou)能(neng)滿足塑(su)化要(yao)求,不發(fa)生降(jiang)(jiang)(jiang)解(jie),并將(jiang)發(fa)泡(pao)溫(wen)度(du)(du)降(jiang)(jiang)(jiang)至比較好(hao)發(fa)泡(pao)領(ling)域。鑒于塑(su)料具(ju)有塑(su)化溫(wen)度(du)(du)和降(jiang)(jiang)(jiang)解(jie)溫(wen)度(du)(du)比較接近的特點,在實際(ji)操(cao)作中(zhong),一方面如(ru)何給制品提供足夠的溫(wen)度(du)(du),保證其良好(hao)塑(su)化,一方面還(huan)應通過擠出(chu)機設置的幾個冷(leng)卻措施來抑(yi)制其降(jiang)(jiang)(jiang)解(jie)。
熔(rong)體(ti)過(guo)塑化或欠塑化不僅影(ying)響(xiang)熔(rong)體(ti)強度(du),也會影(ying)響(xiang)發泡(pao)率(lv)(lv),在擠(ji)出(chu)過(guo)程中各段溫(wen)度(du)設(she)定應(ying)按前高后(hou)低排序,合(he)流(liu)芯溫(wen)度(du)設(she)定至比較低。隨擠(ji)出(chu)壓(ya)力穩步增加,發泡(pao)點(dian)移向模唇,有利于提高發泡(pao)率(lv)(lv)。
若(ruo)擠出機(ji)5區(qu)熔體溫(wen)度過高(gao),遠離口模,不僅會(hui)使(shi)氣體提前發泡,也會(hui)使(shi)熔體溫(wen)度高(gao)而發生(sheng)降解。木(mu)飾面板擠出生(sheng)產線制造商。山西木(mu)飾墻面裝飾板機(ji)器(qi)是什么
