普通樹(shù)脂材料的鏡片特點(diǎn) </p> <p> 普通樹(shù)脂材料：（CR-39） </p> <p> 學(xué)名碳本酸丙烯乙酸，或稱烯丙基二甘醇酸脂（Dially?Glycol?Carbonates），是應(yīng)用*****的生產(chǎn)普通樹(shù)脂鏡片的材料。它于四十年代被美國(guó)哥倫比亞公司的化學(xué)家發(fā)現(xiàn)，是美國(guó)空軍所研制的一系列聚合物中的第39號(hào)材料，因此，被稱為CR-39（哥倫比亞樹(shù)脂第39號(hào)）。CR-39被用于生產(chǎn)眼用矯正鏡片是在1955~1960年，是***代的超輕、抗沖擊的樹(shù)脂鏡片。CR-39作為一種熱固性材料，單體呈液態(tài)，在加熱和加入催化劑的條件下聚合固化。聚合是一個(gè)化學(xué)反應(yīng)，即由幾個(gè)相同分子結(jié)構(gòu)的單體組成的一個(gè)新的聚合體分子，具有不同的長(zhǎng)度和性質(zhì)。作為光學(xué)鏡片，CR-39材料性質(zhì)的參數(shù)十分適宜：折射率為1.5（接近普通玻璃鏡片）、密度1.32（幾乎是玻璃的一半）、阿貝數(shù)為58~59（只有很少的色射）、抗沖擊、高透光率，可以進(jìn)行染色和鍍膜處理。?它主要的缺點(diǎn)是耐磨性不及玻璃，需要鍍抗磨損膜處理。樹(shù)脂鏡片可采用模式壓法加工鏡片表面的曲率，因此很適用于非球面鏡片的生產(chǎn)。龍崗批發(fā)彩鍍鏡片面板批發(fā)比重高（密度大）：即單位體積所含分子數(shù)量多，因此在配戴時(shí)感覺(jué)沉重。</p><div

機(jī)械性質(zhì)通常反映塊狀固體材料的特性，它規(guī)定了材料的質(zhì)量、體積和尺寸，以及材料對(duì)變形和沖擊的抵抗力。我們常見(jiàn)的反映鏡片機(jī)械性質(zhì)的特性有：1、比重；2、硬度；3、彈性系數(shù)E（或楊氏系數(shù)）：壓力和在排除壓力后恢復(fù)**初形狀時(shí)產(chǎn)生的相應(yīng)變形之間的比率。4、抗沖擊性：常采用由美國(guó)食品和***管理局（FDA）規(guī)定的一項(xiàng)落球試驗(yàn)表示。落球試驗(yàn)即使用一個(gè)16克的鋼球從1.27M高處對(duì)準(zhǔn)鏡片中心落下的測(cè)試。5、抗斷開(kāi)點(diǎn)：采用由歐洲標(biāo)準(zhǔn)化**會(huì)制定的"100牛頓"CEN靜態(tài)變形測(cè)試。該測(cè)試是在一個(gè)恒定速度下增加壓力直到100牛頓。

</p> <p> 茶色玻璃鏡片 </p> <p> 添加氧化錳、氧化鐵或氧化鎳等著色。具有吸收紫外線和防眩光的作用，視物層次分明、清晰，可做太陽(yáng)鏡。 </p> <p> 蘭色玻璃鏡片 </p> <p> 添加氧化鈷、氧化鐵、氧化銅和氧化錳等著色。具有防眩光的作用，適合高溫爐前人員的護(hù)目鏡 </p> <p> 黃色玻璃鏡片 </p> <p> 添加硫化鎘、氧化鈰及氧化鈦著色。具有吸收紫外線的作用，且視物清晰、明亮，可適合司機(jī)在陰雨、霧天配戴在沒(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；</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;"

亞克力表面硬化這種板能常用在手機(jī)、顯示屏、儀表面板等各類常被接觸到的顯示面板上。亞克力又叫有機(jī)玻璃，也叫壓克力，是一種高分子聚酯化合物，由于硬度不是很高，也容易產(chǎn)生劃痕，因此表面必須加硬，這個(gè)過(guò)程叫亞克力表面硬化處理，也有的人叫表面鍍膜。????因?yàn)椴挥薪?jīng)過(guò)硬化過(guò)的亞克力板不納劃傷，而通過(guò)表面硬化處理的亞克力板硬度從H能增加到4H以上，所以它的作用是防止劃傷。加上現(xiàn)有工藝和設(shè)備的處理，能夠使防刮花亞克力鏡片大量生產(chǎn)應(yīng)用于手機(jī)屏鏡片

</p> <p> <br /> </p> <p> 光學(xué)性質(zhì)是材料的基本性質(zhì)，與鏡片在日常生活中所見(jiàn)到的各種光學(xué)現(xiàn)象相符合，主要為光線在鏡片表面的折射和反射、材料本身的吸收，以及散射和衍射現(xiàn)象。 </p> <p> （1）光線折射：通過(guò)鏡片的光線會(huì)在鏡片的前后表面發(fā)生折射或偏離現(xiàn)象，光線的偏離幅度由材料的折射率和入射光線在鏡片表面的入射角度決定。??1）折射率：透明媒質(zhì)的折射率是光線在真空中的速度c與在媒質(zhì)中的速度v的比值， </p> <p> n=c/v。該比值沒(méi)有單位并且總是大于1。折射率反映媒質(zhì)的折射能力，折射率越高，從空氣進(jìn)入該媒介的光束偏離得越多。從空氣到折射率為n的透明媒質(zhì)所發(fā)生的偏離或折射可以根據(jù)斯涅耳-笛卡爾定律(Snell-Descartes?Law)進(jìn)行計(jì)算，規(guī)定如下：折射光線與入射光線和法線位于同一平面入射角i和折射角r分別由法線與入射光線、折射光線構(gòu)成。計(jì)算公式：?sin?i=n?sin?r????由于透明媒質(zhì)的光速隨著波長(zhǎng)而變化，所以折射率的值總是參考某一特定波長(zhǎng) </p> <p> 表示：在歐洲和日本，參考波長(zhǎng)為e線546.07nm(汞--綠光譜線)，但是在美國(guó)等其它 </p> <p> 國(guó)家則是d線587.56nm(氦--黃光譜線)。但這個(gè)區(qū)別并沒(méi)有造成實(shí)際影響，因?yàn)樗?</p> <p>
