學名碳本酸丙烯乙酸，或稱烯丙基二甘醇酸脂（Dially?Glycol?Carbonates），是應用*****的生產普通樹脂鏡片的材料。它于四十年代被美國哥倫比亞公司的化學家發(fā)現(xiàn)，是美國空軍所研制的一系列聚合物中的第39號材料，因此，被稱為CR-39（哥倫比亞樹脂第39號）。CR-39被用于生產眼用矯正鏡片是在1955~1960年，是***代的超輕、抗沖擊的樹脂鏡片。CR-39作為一種熱固性材料，單體呈液態(tài)，在加熱和加入催化劑的條件下聚合固化。聚合是一個化學反應，即由幾個相同分子結構的單體組成的一個新的聚合體分子，具有不同的長度和性質。作為光學鏡片，CR-39材料性質的參數(shù)十分適宜：折射率為1.5（接近普通玻璃鏡片）、密度1.32（幾乎是玻璃的一半）、阿貝數(shù)為58~59（只有很少的色射）、抗沖擊、高透光率，龍崗pc油漆鏡片面板**膠，可以進行染色和鍍膜處理。?它主要的缺點是耐磨性不及玻璃，需要鍍抗磨損膜處理。樹脂鏡片可采用模式壓法加工鏡片表面的曲率，因此很適用于非球面鏡片的生產，龍崗pc油漆鏡片面板**膠。大家可能平常都會遇到，龍崗pc油漆鏡片面板**膠，玻璃做的杯子啊，什么的打碎了。龍崗pc油漆鏡片面板**膠</p><div

玻璃鏡片的主要原料是光學玻璃。其折射率比樹脂鏡片高，因此在同樣度數(shù)情況下，玻璃鏡片要比樹脂鏡片薄。玻璃鏡片的透光率和機械化學性能都比較好，有恒定的折射率、理化性能穩(wěn)定。沒有顏色的鏡片稱光學白托（白片），有**中的粉紅片稱克羅克賽鏡片（紅片）。克羅克賽鏡片能吸收紫外線、對強光略有吸收作用。 </p> <p>

對于玻璃鏡片來說，質量與硬度相對較大，容易摔碎，但是耐刮以及耐磨，很少出現(xiàn)有劃痕。 </p> <p> 但是如果出現(xiàn)劃痕的話，不容易修復，大多數(shù)只能更換鏡片，因為就算是修復好后，透光率以及折射率會降低，影響了鏡片的佩戴效果。 </p> <p> 樹脂鏡片 </p> <p> 樹脂鏡片相對來說質量較輕，不易摔碎，所以是目前**安全的鏡片之一。 </p> <p> 但是樹脂鏡片容易出現(xiàn)劃痕，這時可以用細純棉布沾上少量牙膏，在有劃痕的地方來回擦拭。 </p> <p> 記得力量不要過重，并且只能按一個方向來回擦拭，就像是做直線運動一樣的擦拭，因為就算是修復好的鏡片，可能還是會降低了鏡片的光學性能。 </p> <p> <br /> 透紅外亞克力板工作原理：各種紅外感應上，主要功能是濾除可見光能雜散光。</p><div

對該材料進行磨削和磨邊時必須小心，它與CR-39的工藝不同。以聚碳酸酯為例，熱塑性材料的制造工藝是將由透明顆粒組成的原材料加熱后注入鏡片模子。該技術是通過加熱液化原材料，再使用活塞將其注入金屬或玻璃模子。在整個制造過程中，螺桿不但起了活塞的作用，通過各通道將熱材料推入模腔，而且確保了注入模腔內的材料的可塑性。在注入和冷卻一段時間后，打開模子，取出鏡片。 </p> <p> 具體的制造步驟如下： </p> <p> （1）材料準備：用熱氣吹干顆粒，并將材料加入壓力機； </p> <p> （2）設置壓力機：取出模子，設置壓力、模子溫度、注射和冷卻的時間，并加熱材料（大約到300°C/570F）； </p> <p> （3）注射：通過壓力將熔化的材料注入模子； </p> <p> （4）冷卻：通過模子傳導使材料固化； </p> <p>
