</p> <p> 偏光片的生產(chǎn)流程 </p> <p> 染色，延伸，貼合，干燥為**主要的步驟，其中染色材料配方是重要的技術(shù)關(guān)鍵。另外PVA的延伸定向控制也會(huì)影響偏光膜的光學(xué)特性。高分子膜在經(jīng)過延伸之后，通常機(jī)械性質(zhì)會(huì)降低，變得易碎裂;且PVA膜具有親水性，在濕熱的環(huán)境下很快會(huì)變形、收縮，江蘇綜合配向角測(cè)試儀、衰退，所以在偏光基體PVA延伸完后，要在兩側(cè)貼上三醋酸纖維(TAC)所組成的透明基板，一方面可做保護(hù)，江蘇綜合配向角測(cè)試儀，一方面則可防止膜的回縮。波長(zhǎng)分散性測(cè)試定義：在波長(zhǎng)400nm-800nm下相位延遲量的曲線。江蘇綜合配向角測(cè)試儀</p><div
