EVA膠片在玻璃深加工中容易出現什么問題?

2019-10-10 741

  溫(wen)度過高:①熔膠(jiao)易流(liu)出,形成邊部膠(jiao)量少及(ji)脫膠(jiao)問題;②制品簡(jian)單呈現雞爪痕等

  溫度過低:膠(jiao)片(pian)中的粘結劑(ji)不能(neng)跟玻璃充沛產生(sheng)粘結反響,簡單產生(sheng)脫膠(jiao)現象。由于各家爐子升溫快慢不同,空間大小不同,所用(yong)玻璃、飾材(cai)、膠(jiao)片(pian)厚(hou)度不同,測溫點不同,所以加(jia)工溫度不能(neng)太呆板,溫度以膠(jiao)片(pian)消融后(hou)流出一點,但又不能(neng)太多(溢出膠(jiao)厚(hou)2mm左右最好)。

  保(bao)(bao)溫時(shi)刻(ke):保(bao)(bao)溫時(shi)刻(ke)短(duan),膠(jiao)片(pian)里(li)的粘結成分與玻璃反響不充沛,簡(jian)單產生(sheng)脫膠(jiao)現(xian)象;保(bao)(bao)溫時(shi)刻(ke)越長(chang),粘接(jie)力越強(qiang);保(bao)(bao)溫時(shi)刻(ke)的長(chang)短(duan)應根據設備的特性來定。單層(ceng)(ceng)爐保(bao)(bao)溫時(shi)刻(ke)短(duan),雙(shuang)層(ceng)(ceng)和多層(ceng)(ceng)爐保(bao)(bao)溫時(shi)刻(ke)長(chang),對玻璃厚、飾材厚、膠(jiao)片(pian)厚及五顏六色(se)膠(jiao)片(pian)要恰當延伸保(bao)(bao)溫時(shi)刻(ke)。

  升高加(jia)工(gong)溫(wen)度(du):對玻璃厚(hou)、飾材厚(hou)、膠片厚(hou)、五顏六色(se)膠片、多層爐要(yao)恰(qia)當進(jin)步加(jia)工(gong)溫(wen)度(du)。

  延伸(shen)保(bao)溫時刻(ke):當溫度(du)到達(da)加工要(yao)求(qiu)后,對玻璃厚、飾(shi)材厚、膠(jiao)片厚、五顏六(liu)色膠(jiao)片要(yao)恰(qia)當延伸(shen)保(bao)溫時刻(ke),目的便是讓膠(jiao)片里的粘結(jie)劑充沛與玻璃發作粘結(jie)反響。

  濕度過(guo)大:影響膠片(pian)粘結力脫膠或產生氣泡。

  爐內溫度不均勻(yun):玻璃(li)受(shou)熱(re)不均勻(yun),影響粘結力產生脫膠、起霧現象。

  玻(bo)璃表(biao)面(mian)溫(wen)(wen)(wen)(wen)(wen)(wen)(wen)度(du)(du)(du)與熱空(kong)氣溫(wen)(wen)(wen)(wen)(wen)(wen)(wen)度(du)(du)(du)(測(ce)溫(wen)(wen)(wen)(wen)(wen)(wen)(wen)點):測(ce)溫(wen)(wen)(wen)(wen)(wen)(wen)(wen)點在硅膠(jiao)(jiao)袋(dai)外的溫(wen)(wen)(wen)(wen)(wen)(wen)(wen)度(du)(du)(du)稱(cheng)熱空(kong)氣溫(wen)(wen)(wen)(wen)(wen)(wen)(wen)度(du)(du)(du),盡管爐內溫(wen)(wen)(wen)(wen)(wen)(wen)(wen)度(du)(du)(du)到(dao)達了要求,但袋(dai)內溫(wen)(wen)(wen)(wen)(wen)(wen)(wen)度(du)(du)(du)還很(hen)低,達不到(dao)加工(gong)要求,需求盡量延(yan)伸保(bao)溫(wen)(wen)(wen)(wen)(wen)(wen)(wen)時(shi)刻(ke)(ke),讓袋(dai)內溫(wen)(wen)(wen)(wen)(wen)(wen)(wen)度(du)(du)(du)到(dao)達工(gong)藝要求并(bing)充沛發(fa)作粘結反響,避免產生脫膠(jiao)(jiao)現(xian)象;假如測(ce)溫(wen)(wen)(wen)(wen)(wen)(wen)(wen)點在硅膠(jiao)(jiao)膠(jiao)(jiao)袋(dai)內稱(cheng)玻(bo)璃表(biao)面(mian)溫(wen)(wen)(wen)(wen)(wen)(wen)(wen)度(du)(du)(du),很(hen)簡單(dan)控制溫(wen)(wen)(wen)(wen)(wen)(wen)(wen)度(du)(du)(du)和保(bao)溫(wen)(wen)(wen)(wen)(wen)(wen)(wen)時(shi)刻(ke)(ke)。

  單層(ceng)加(jia)工(gong)爐(lu)(lu)與多層(ceng)加(jia)工(gong)爐(lu)(lu):單層(ceng)爐(lu)(lu)升溫快(kuai),保溫時刻(ke)短;多層(ceng)爐(lu)(lu)升溫慢,保溫時刻(ke)長(chang),在生產時,應根據自身設(she)備(bei)的特色探索、調整(zheng)加(jia)工(gong)工(gong)藝。
