玻璃鏡片的主要原料是光學(xué)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(jī)械化學(xué)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(xué)白托（白片），有**中的粉紅片稱克羅克賽鏡片（紅片）?？肆_克賽鏡片能吸收紫外線、對(duì)強(qiáng)光略有吸收作用。 </p> <p>

對(duì)該材料進(jìn)行磨削和磨邊時(shí)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(shù)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(gè)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(nèi)的材料的可塑性。在注入和冷卻一段時(shí)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(zhǔn)備：用熱氣吹干顆粒，并將材料加入壓力機(jī)； </p> <p> （2）設(shè)置壓力機(jī)：取出模子，設(shè)置壓力、模子溫度、注射和冷卻的時(shí)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(dǎo)使材料固化； </p> <p> （5）開模：打開壓力和模子，取出鏡片而在紫外線輻射下，不穩(wěn)定電子離開了氯離子，與銀離子結(jié)合為金屬銀并吸收光，鏡片則變深。松崗批發(fā)彩鍍鏡片面板哪家好</p><p
