阿科瑪PMMA亞克力透明
阿科瑪PMMA亞克力透明
PMMA樹脂是無毒環(huán)保的材料,可用于生產(chǎn)衛(wèi)生潔具等,具有良好的化學(xué)穩(wěn)定性、和耐候性。PMMA樹脂在破碎時不易產(chǎn)生尖銳的碎片,美國,日本等國家和地區(qū)已在法律中作出強制性規(guī)定,中小學(xué)及幼兒園建筑用玻璃必須采用PMMA樹脂。目前,全國各地加快了城市建設(shè)步伐,街頭標志、廣告燈箱和電話亭等大量出現(xiàn),其中所用材料中有相當(dāng)一部分是PMMA樹脂。北京奧運工程的戶外彩建材也大量使用了綠環(huán)保的PMMA樹脂。

注塑模工藝條件:
干燥處理:PMMA具有吸濕性因此加工前的干燥處理是必須的。建議干燥條件為90C、2-4小時。
熔化溫度:240-270C。 模具溫度:35-70C。
注射速度:中等
化學(xué)和物理特性PMMA具有優(yōu)良的光學(xué)特性及耐氣侯變化特性。白光的穿透性高達92%。PMMA制品具有很低的雙折射,特別適合制作影碟等。PMMA具有室溫蠕變特性。隨著負荷加大、時間增長,可導(dǎo)致應(yīng)力開裂現(xiàn)象。PMMA具有較好的抗沖擊特性。
由于PMMA表面硬度不高、易擦毛、抗沖擊性能低、成型流動性能差等缺點,PMMA的改性相繼出現(xiàn)。如甲基丙烯酸甲酯與苯乙烯、丁二烯的共聚,PMMA與PC的共混等。 超級透明PMMA材料主要用于手機保護屏,該產(chǎn)品分為有硬化涂層,沒有硬化涂層兩種.其特點是透光率極好,沒有雜質(zhì),靜電保護膜,表面硬化厚后硬度可達5-6H以上. 目前特別推薦用于硬化處理的PMMA材料,國內(nèi)稱為生板。
