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(guò)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(guò)程中，螺桿不但起了活塞的作用，通過(guò)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(kāi)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(guò)壓力將熔化的材料注入模子； </p> <p> （4）冷卻：通過(guò)模子傳導(dǎo)使材料固化； </p> <p> （5）開(kāi)模：打開(kāi)壓力和模子，取出鏡片 </p><p> 鏡片的光線散射和衍射 </p> <p> 光線散射和衍射 </p> <p> (1)散射：散射是光線在各個(gè)方向上被散播的一種現(xiàn)象，它一般在固體的表面以及透 </p> <p>

作為光學(xué)材料，水晶的比較大優(yōu)點(diǎn)是硬度大，制成的鏡片不易磨損。在本世紀(jì)20－30年代曾流行一時(shí)。因其制成的鏡片經(jīng)久耐用，又因其價(jià)格十分昂貴，常常留傳給下一代。 </p> <p> 在民間有：“水晶養(yǎng)目”之說(shuō)。 </p> <p> 水晶的主要成分是SiO2，是一種天然透明礦物質(zhì)。 </p> <p> （1）水晶對(duì)紅外線、紫外線的吸收率差。 </p> <p> 對(duì)紫外線的吸收率*為14.5％，而玻璃對(duì)紫外線的吸收率是52％，目前加入U(xiǎn)V材料的樹(shù)脂鏡片對(duì)紫外線的吸收率已高達(dá)到90％以上. </p> <p> （2）天然水晶常含有雜質(zhì)，密度不均勻，會(huì)出現(xiàn)氣泡和條紋而產(chǎn)生雙折射現(xiàn)象，從而影響視力。 </p> <p> 由此可見(jiàn)，水晶不但不具有養(yǎng)目的作用，其對(duì)紫外線的高透過(guò)率是對(duì)眼睛有害的。在科學(xué)技術(shù)飛速發(fā)展的***，新的光學(xué)材料樹(shù)脂制作的眼鏡片，無(wú)論其光學(xué)性能、安全性能、防止有害射線保護(hù)眼睛的性能都遠(yuǎn)遠(yuǎn)優(yōu)于水晶水晶石熔點(diǎn)為1713攝氏度，放在火爐中鍛燒后再放人冷水中仍不炸裂；光明定制鏡片面板**膠</p><p
