如果采用的是無PC鏡片工藝設定的手動或半自動磨邊機，則要在粗磨階段人工斷水，東莞pcpc鏡片茶色，進行干磨。但在細磨進行至***1至2轉可開啟水源加水細磨，可使鏡片邊緣較光亮，東莞pcpc鏡片茶色。 </p> <p> 現(xiàn)在有些***的全自動磨邊機配有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膠紙。它可以起到防刮花的預防措施，還有助于防止鏡片在磨邊時滑動和減少在磨邊時吸盤給減反膜鏡片帶來過多的壓力。如果吸盤的壓力過高，鏡片會在磨邊時彎曲，從而引起鏡片的膜層龜裂。在貼保護膠紙之前，要確定鏡片的表面是干凈的。?盡可能用現(xiàn)代的全自動磨邊機，因為這些磨邊系統(tǒng)都帶有轉為PC鏡片及AR或超防水膜鏡片設計的磨邊程序。

PC是無色透明，光潔美觀的塑料。由于PC***、無異味，阻止紫外線透過性能及防潮保香性能好，耐溫范圍廣，在－180℃下不脆裂，在130℃環(huán)境下可長期使用，所以是一種理想的食品包裝材料。利用PC耐沖擊性能佳、易成型的特點，可制造成瓶、罐及各種形態(tài)的容器，用于包裝飲料、酒類、牛奶等流體物質。 PC比較大缺點即是產(chǎn)生應力開裂。生產(chǎn)中除了選用高純度原料，嚴格控制各種加工條件外，采用內應力小的樹脂改性，如少量的聚烯烴、尼龍、聚酯等熔融共混，可***改進抗應力開裂性、抗水性。 </p><p> 根據(jù)PC鏡片還具有比重輕，抗沖擊強度大，韌性高等物理性能，PC鏡片相對其他樹脂鏡片具備更輕、更韌、更環(huán)保等優(yōu)點。 </p> <p> 而PC鏡片的缺點也是顯而易見的。比如PC鏡片的加工難度大，加硬需要特定的技術，多數(shù)廠商制造的PC鏡片在耐磨性上達不到要求，容易刮花；此外還需要**的磨邊設備來磨制。 </p> <p> 平板鏡片燙金工藝：燙金的實質是轉印，是把燙金紙上面的圖案通過熱和壓力的作用轉移到承印物上面的工藝過程。燙印時，燙金紙的粘結層熔化，與承印物表面形成附著力，同時燙金紙的離型劑的硅樹脂流動，與載體薄膜發(fā)生分離，載體薄膜上面的圖文就被轉移到承印物上面。燙金可以燙金色、銀色、鐳射及拉絲等許多效果，可**豐富鏡片裝飾效果。 </p> <p> 平板鏡片燙金工藝：可適用于:IML鏡片，平板鏡片，注塑鏡片。 </p> <p> <br /> </p> <p> <br /> 深圳PMMA.PC手機鏡片生產(chǎn)廠家哪家好?</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;"

樹脂鏡片是一種以樹脂為原材料經(jīng)過精密的化學工藝進行加工合成和打磨后制作而成的一種光學鏡片。同時樹脂又可分為天然樹脂和合成樹脂兩種。 </p> <p> 樹脂鏡片的優(yōu)點：抗沖擊強，不易碎，透光性好，折射率高、質量輕，成本低廉。 </p> <p> pc鏡片是用聚碳酸酯(熱塑性材料)經(jīng)過加熱后塑形而成的一種鏡片。這種材料它是源于太空探險而研制成的，故又被稱為宇宙片或太空片。由于PC樹脂是一種性能優(yōu)良的熱塑性材料，所以特別適宜制作眼鏡片。 </p> <p> PC鏡片的優(yōu)點：**紫外線，3-5年之內不會發(fā)黃，***的抗沖擊能力，折射率高、比重輕(重量比普通樹脂片輕37%，抗沖擊力更是高達普通樹脂的12倍) PC鏡片在美國市場的份額為35%。光明高清pc鏡片原料</p><p style="text-indent:25px">目前，PC鏡片主要包括PC常規(guī)鏡片、PC漸進鏡片、PC變色鏡片、PC偏光鏡片、PC抗藍光鏡片等。東莞pcpc鏡片茶色</p><p> PC鏡片上打吸盤磨邊 </p> <p> PC鏡片上打吸盤準備磨邊，與對待其它材料沒什么不一樣。避免吸盤在鏡片上超過一小時，因為一些吸盤與鏡片表面膜層接觸時間過長就會粘在一起，會對膜層有所傷害。 </p> <p> 一般人習慣把小吸盤打在鏡片的光學中心。當所要加工的PC鏡片的寬度（A值）比高度（B值）大許多，例如長方形或扁橢圓形，而瞳距又要求移光心時，建議將吸盤打在鏡片的幾何中心。這樣可以避免因過度不對稱而導致磨邊過程中鏡片變形，給裝鏡帶來麻煩. </p> <p> 如果磨邊輪（或刀）保持鋒利的話，大多數(shù)典型的磨邊設備都可以切出滿意的PC鏡片。磨邊的粗磨階段要干磨，避免用冷卻液（水），而在精磨或拋光階段可以濕磨。因為產(chǎn)生的熱量**小，刀式干切法比較適合PC鏡片的磨邊。但市面上的大部分磨邊機是輪式的。這種輪式磨邊機配上為PC鏡片設計的粗磨輪也完全滿足要求，只是濕磨階段的磨削速度一定不能過快。磨邊腔室要保持干凈。若發(fā)現(xiàn)鉆石輪上有殘屑，可用玻璃片或竹筷子***。磨片過程中若鏡片周圍有較大塊之殘屑，可以手輔助取下以方便磨片之進行，避免對鏡片造成傷害。磨邊機需定期清洗，保持清潔。東莞pcpc鏡片茶色</p><p
