消除原料樹脂、色母的影響
控制原材料是解決色差的關(guān)鍵。因此，尤其是生產(chǎn)淺色制品時(shí)，不能忽視原料樹脂的熱穩(wěn)定性不同對(duì)制品色澤波動(dòng)帶來的明顯影響。鑒于大多數(shù)注塑生產(chǎn)廠家本身并不生產(chǎn)塑料母料或色母，這樣，可將注意的焦點(diǎn)放在生產(chǎn)管理和原材料檢驗(yàn)上。即加強(qiáng)原材料入庫(kù)的檢驗(yàn)；生產(chǎn)中同一產(chǎn)品盡可能采用同一廠家、同一牌號(hào)母料、色母生產(chǎn)；對(duì)于色母，我們?cè)谂可a(chǎn)前要進(jìn)行抽檢試色，既要同上次校對(duì)，又要在本次中比較，如果顏色相差不大，可認(rèn)為合格，如同批次色母有輕微色差，可將色母重新混合后再使用，以減少色母本身混合不均造成的色差。同時(shí)，我們還需重點(diǎn)檢驗(yàn)原料樹脂、色母的熱穩(wěn)定性，對(duì)于熱穩(wěn)定性不佳的，我們建議廠家進(jìn)行調(diào)換。
