克羅克斯鏡片（Crookes） </p> <p> 由英國(guó)人威廉.克羅克斯于1914年發(fā)明，故命名為克羅克斯鏡片，簡(jiǎn)稱克斯片。克斯片分為普通和光學(xué)克斯片兩種。普通克斯片簡(jiǎn)稱光克片，是在鋇冕玻璃成分中添加微量 </p> <p>

光致變色玻璃材料鏡片特點(diǎn)光致變色現(xiàn)象是通過(guò)改變材料光線吸收屬性，使材料對(duì)太陽(yáng)光強(qiáng)度作出反應(yīng)的一種性質(zhì)。它的基本原則是使普通的玻璃（包括塑料光致變色材料）在紫外線輻射的影響下顏色變深，以及在周圍高溫的影響下顏色變淡，這兩個(gè)過(guò)程是可逆的，而且可能一直存在。這一現(xiàn)象是通過(guò)***在材料中混合光致變色物質(zhì)的分子而完成。1962年出現(xiàn)了***代光致變色玻璃材料,此后性能不斷得到改良。其主要是在玻璃材料中加入了鹵化銀晶體。這些晶體在紫外線擊幅射下起化學(xué)反應(yīng)，鏡片的顏色變深。***代光致變色玻璃材料的變色原理是銀原子和氯原子之間的一種電子交換，通過(guò)氯化銀和周圍的環(huán)境表現(xiàn)。在沒(méi)有光線條件下，氯化銀呈離子態(tài)，因銀離子是透明的，所以鏡片也是透明的；而在紫外線輻射下，不穩(wěn)定電子離開(kāi)了氯離子，與銀離子結(jié)合為金屬銀并吸收光，鏡片則變深。當(dāng)紫外線輻射減弱，移動(dòng)電子離開(kāi)銀原子返回氯原子，鏡片逐漸恢復(fù)了原先的清澈狀態(tài)。對(duì)一般光致變色玻璃，變色同時(shí)也受到溫度控制，在光照度不變時(shí)，溫度越低則顏色越深。光致變色材料大多是灰色和棕色的，俗稱灰變和茶變，其它的顏色也可以通過(guò)專門的工藝達(dá)到。所有的眼鏡片。深圳cnc手機(jī)鏡片面板哪家好化學(xué)和物理特性:

鏡片材料采用透明的介質(zhì)，主要分為無(wú)機(jī)和有機(jī)二大類。在我們的日常生活還會(huì)碰到一種天然介質(zhì)水晶鏡片，這是用石英礦磨制成的鏡片。古代有水晶能養(yǎng)顏明目的說(shuō)法，但事實(shí)上水晶的主要成分是二氧化硅（sio2），比較大優(yōu)點(diǎn)是硬性度高且不易受潮，但紫外線及紅外線的透過(guò)率較高，而且水晶中密度不均勻，含雜質(zhì)，有條紋及氣泡等到產(chǎn)生，會(huì)形成雙折射現(xiàn)象，從而影響視力。無(wú)機(jī)材料--玻璃，玻璃是非常特殊的不定型材料，在常溫下呈現(xiàn)固體，堅(jiān)硬但易碎，在高溫下具有粘性。玻璃沒(méi)有固定的化學(xué)結(jié)構(gòu)，因而沒(méi)有確切的熔點(diǎn)。隨著溫度的上升，玻璃材料會(huì)變軟、粘性增加，并逐漸由固體變?yōu)橐后w，這種逐漸變化的特性我們稱之為"玻璃狀態(tài)"。這一特性意味著玻璃在高溫時(shí)可以被加工和鑄型。玻璃材料制成的鏡片具有良好的透光性、表面拋光后更加透明的優(yōu)點(diǎn) </p><p> 熱塑性材料鏡片的工藝 </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(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，取出鏡片結(jié)合了兩種材料的優(yōu)異特性，ABS材料的成型性和PC的機(jī)械性、沖擊強(qiáng)度和耐溫、抗紫外線（UV）等性質(zhì)。</p><div style="width:100%;text-align: center;"><img
