7，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；而仿制品無(wú)固定熔點(diǎn)，加熱至高溫后放人水中立即炸裂。天然的水晶鏡片有瑕疵,那兩塊偏光鏡片夾住看的話(huà)就會(huì)看的到.光明批發(fā)鏡片面板**膠</p><div style="width:100%;text-align: center;"><img style="max-width:

鏡片普通玻璃材料與高折射率玻璃材料 </p> <p> （1）普通玻璃材料（1。5和1。6）：折射率為1.523的冕牌玻璃是傳統(tǒng)光學(xué)鏡片的制造材料，其中60%~70%為二氧化硅，其余則由氧化鈣、鈉和硼等多種物質(zhì)混合。有時(shí)也將折射率為1.6的鏡片劃歸普通鏡片。 </p> <p> （2）高折射率玻璃材料：經(jīng)過(guò)多年的研究，鏡片制造商已經(jīng)找到了在提高材料折射率的同時(shí)又保持低色散的方法，即在玻璃中加入新的化學(xué)元素。????早在1975年就生產(chǎn)出了含鈦元素的鏡片，折射率為1.7，阿貝數(shù)為41；15年之后又生產(chǎn)出了含鑭元素的鏡片，折射率為1.8，阿貝數(shù)為34；1995年出現(xiàn)折射率為1.9的材料，加入了元素鈮，阿貝數(shù)為30，這是目前折射率比較高的鏡片材料。雖然采用這些材料所制造的鏡片越來(lái)越薄，然而卻沒(méi)有減少鏡片的另一重要參數(shù)：重量。實(shí)際上，隨著折射率的增加，材料的比重也隨之增加，這樣就抵消了因?yàn)殓R片變薄而帶來(lái)的重量上的減輕。這些晶體在紫外線(xiàn)擊幅射下起化學(xué)反應(yīng)，鏡片的顏色變深。</p><div

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，取出鏡片使材料對(duì)太陽(yáng)光強(qiáng)度作出反應(yīng)的一種性質(zhì)。龍華pc鏡片面板加工</p><p

光學(xué)樹(shù)脂鏡片基本分類(lèi)PMMA鏡片：PMMA屬熱塑性材料，早在五十年代就被***用于制造鏡片，但是由于受熱易變形及耐磨性較差的缺點(diǎn)，很快就被CR-39所替代。用PMMA生產(chǎn)的鏡片（主要有太陽(yáng)鏡鏡片、角膜接觸鏡）PC太空片：聚碳酸酯是直線(xiàn)形無(wú)定型結(jié)構(gòu)的熱塑聚合體，具有許多光學(xué)方面的優(yōu)點(diǎn)：出色的抗沖擊性能（是CR39的10倍以上），高折射率（ne=，nd=），非常輕（比重=），**抗紫外線(xiàn)（385nm），耐高溫（軟化點(diǎn)為140℃）。（主要有工業(yè)用護(hù)目鏡片、偏光鏡片、體育運(yùn)動(dòng)用鏡片等。）中高折射率樹(shù)脂材料：***大部分的中折射率(n=)和高折射率(n>)材料都是熱固性樹(shù)脂，其發(fā)展非常迅速。它們的折射率可以使用以下任意一種技術(shù)來(lái)增加：改變?cè)肿又须娮拥慕Y(jié)構(gòu)，例如：引入苯環(huán)結(jié)構(gòu)；在原分子中加入重原子，諸如鹵素（氯、溴等）或硫。與傳統(tǒng)CR-39相比，用中高折射率樹(shù)脂材料制造的鏡片更輕、更薄。染色樹(shù)脂材料：用于制造太陽(yáng)眼鏡鏡片的基本上都是聚合前加入染料而制成的，特別適合大批量制造各色平光太陽(yáng)鏡片，同時(shí)在材料中加入可吸收紫外線(xiàn)的物質(zhì)。鏡片的顏色取決于紅黃藍(lán)三原色的搭配，可以染成各種不同的顏色。染色方法：熱浸泡法鏡片顏色的濃度取決于（染料的濃）（浸泡的時(shí)間）、。光明批發(fā)鏡片面板**膠</p></p><br
