C、透光率是視物清晰度的重要指標(biāo)，無(wú)色光學(xué)玻璃對(duì)可見光的透光率應(yīng)在92%以上。透光率越高，視物就越清晰。 </p> <p> （4）機(jī)械性能 </p> <p> 主要包括比重（密度）、硬度、表面張力和彈性系數(shù)等。 </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(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）開模：打開壓力和模子，取出鏡片龍崗pc鏡片面板哪家好</p></p><br /><p>文章來(lái)源地址: http://www.cdcfah.com/cp/2843228.html</p></div></div></div></div></div><div id="xpzl57t"
