注塑鏡片注塑成型鏡片是由PMMA和PC顆粒經(jīng)注塑、硬化、印刷、修剪獲得的鏡片，其材料主要有PC和PMMA。PC：PC的透光率在88%以上，鏡片韌性好，耐沖擊。但其表面硬度低，注塑完后表面硬度一般為4B左右，經(jīng)過(guò)硬化處理后，硬度也*為HB左右。鏡片在使用過(guò)程中易被劃傷。PMMA：和PC相比，PMMA的透光率高，可達(dá)93%。耐候性好，不易氧化、開裂。表面硬度未經(jīng)過(guò)硬化也可以達(dá)到H以上，經(jīng)過(guò)硬化后，硬度可以達(dá)到3H以上。注塑成型后PMMA的硬度超過(guò)硬化后的PC，如果對(duì)鏡片鏡片表面的硬度及沖擊性能要求不高，鳳崗pc鏡片硬度，鳳崗pc鏡片硬度，甚至可以不用強(qiáng)化，直接制作鏡片，鳳崗pc鏡片硬度，達(dá)到降低成本的目的。

.PC鏡片不會(huì)像樹脂鏡片那樣產(chǎn)生大量粉塵。如果在磨片機(jī)下水管末端加裝一般能粗濾網(wǎng)或蚊帳布以過(guò)濾磨片時(shí)所產(chǎn)生的粉屑，可采用循環(huán)水的方式，可以節(jié)約水費(fèi)。 </p> <p> 如果采用的是無(wú)PC鏡片工藝設(shè)定的手動(dòng)或半自動(dòng)磨邊機(jī)，則要在粗磨階段人工斷水，進(jìn)行干磨。但在細(xì)磨進(jìn)行至***1至2轉(zhuǎn)可開啟水源加水細(xì)磨，可使鏡片邊緣較光亮。 </p> <p> 現(xiàn)在有些***的全自動(dòng)磨邊機(jī)配有CR-39/Poly皆可使用之鉆石輪。?建議在AR尤其是超防水膜鏡片上吸盤磨邊前使用表面保護(hù)膠紙。它可以起到防刮花的預(yù)防措施，還有助于防止鏡片在磨邊時(shí)滑動(dòng)和減少在磨邊時(shí)吸盤給減反膜鏡片帶來(lái)過(guò)多的壓力。如果吸盤的壓力過(guò)高，鏡片會(huì)在磨邊時(shí)彎曲，從而引起鏡片的膜層龜裂。在貼保護(hù)膠紙之前，要確定鏡片的表面是干凈的。?盡可能用現(xiàn)代的全自動(dòng)磨邊機(jī)，因?yàn)檫@些磨邊系統(tǒng)都帶有轉(zhuǎn)為PC鏡片及AR或超防水膜鏡片設(shè)計(jì)的磨邊程序。

常見的鏡片材料包括玻璃鏡片及樹脂鏡片兩類。1960年，美國(guó)PPG公司將原***CR-39(樹脂)材料轉(zhuǎn)為民用，開始用于制造鏡片;1979年，在發(fā)達(dá)國(guó)家中，鏡片材料由玻璃向CR-39(樹脂)轉(zhuǎn)型，結(jié)束了玻璃鏡片接近600年的統(tǒng)治地位;1985年，美國(guó)Vision-Ease鏡片公司率先推出PC***鏡片;1991年，美國(guó)Transitions(全視線)公司，推出***代變色樹脂鏡片;1995年，偏光PC鏡片誕生。 </p> <p> PC中文名為聚碳酸酯，英文名為Polycarbonate，是一種強(qiáng)韌的熱塑性樹脂，在五大工程塑料中屬增長(zhǎng)速度**快的通用工程塑料。由于PC具有強(qiáng)抗撞擊性、耐磨、防眩光、不易發(fā)黃變色等特點(diǎn)，目前***應(yīng)用于眼鏡產(chǎn)品上，屬于第三代鏡片。PC鏡片比樹脂鏡片輕30%，比玻璃鏡片輕50%左右，而且具有**防紫外線的效果，目前已在歐美等發(fā)達(dá)國(guó)家被***推廣應(yīng)用。 </p> <p> <br /> 通過(guò)引進(jìn)美國(guó)先進(jìn)技術(shù)，PC變色鏡片1分鐘內(nèi)變色可超過(guò)88%。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="鳳崗pc鏡片硬度,pc鏡片"
