4. 3对电气石作同频同源红外电磁波共振活化处理的结果, 可以 同批次烘千干燥的电气石活化前 ε 值和负离子发生 Q值与活化后的 粉体同条件实测值作比较对比。当全波段法向积分幅射率后者 e值提 高不低于一个百分点, Q值提高不低于 10个百分点时。 将视为达标, 否则可适当提高热处理温度, 但不能超过 800°C。 ε 值是指负离子发 射率; Q值是指全发射法向发射率。 4. 4活化后的电气石粉作表面改性, 方法为用偶联剂与粉体雾化 混搅, 在高速剪切分散机或高速搅拌机中完成。偶联剂类别与品种的 选择以后来配伍的有机树脂的性质与成份,以及膜理化性质的选择性 需要而定。 在电气石颗粒较大、 径级比小、 均匀度较高时, 彼如 5— 8微米的混级粉体也可以用硅油代替, 如氨基硅油、 二甲基硅油等。 偶联剂与硅油的投放量在 0. 5- 2%之间, 以电气石颗粒表面浸润包裹 充分, 不同径粒及相同径粒的互粘自聚现象消失, 而呈现出高度自由 分散状态为准。
4. 5 设计为无机 /有机线性光学 (塑料) 系统的电气石有机膜, 为充分满足人体 2. 5-16微米的红外线需要, 为进一步提高 "膜"的 生态多功能性,我们将电气石为主的与无机功能矿物沸石作有红外光 谱迭加性的双组份组合外,又引入同样有红外辐射特征且具有半导体 光能媒体的 Ti02 (金红石型)。 沸石在前述的电气石为涂料的炉中经 受了 400Ό的红外活化, Ti02则是为焙烧料。 黑色电气石的微纳米粒 子因光干涉而表面色泽变浅, 无机组合料是灰白色的,将它们搅拌投 入到浅黄色的液状热固型复配脲醛树内将上述预混料混合搅拌,即成 预混料。 配方配比如下: 电气石 14g, 丝光沸石 6. 0g, 金红石型 Ti026. 0g, 丁醚化树脂 (固形物 50%) 21g, 蓖麻油醇酸树脂 38g, 二 甲苯 llg, 正丁醇 4g。
4. 6 将上述预混料放在石英坩埚中用电磁搅拌继续加热在呈现 粘胶状时, 取其热液在不锈钢板上(可加脱膜剂)分别做无应力的漫 溢自流平成膜和有预应力的石辊碾压或平板铅垂正压力下的有限剪 切展延性成膜, 将二相近厚度的膜一并放在烘箱中, 在 120°C— 130 Ό经 20— 30分钟后固化。用刀片刮取同厚度膜, 选在偏光显微镜下, 粒度分布相似且面积相同的二片,分别做静态和动态的负离子 Q值测 试, 结果为预应力型是自流平型的 1. 3倍。
5、 活化后的电气石, 其内能增加, 表面能增加, 电气石无机 / 有机预应力膜,其复合成功的意义在于刚性与柔性的结合使它们两者 弹性膜量的巨大差异成为压敏电气石工作的良好信号发生与传递体 的优势所在。不论电气石放在热塑性树脂, 热固性树脂还是紫外光固 化的光敏树脂中, 固化后的弹性膜量不过 10Ll0:iMpa, 在这个范围 内人的体重和足下的蹬踏压力可以向电气石发出有效的工作信号,从 而促进功能反应,同时因电气石又是热膨胀系数很大的热敏一热释电 晶体, 在薄如蝉翼的透明光学系统里, 可见光的能量就可以使电气石 又产生相应的功能性提高, 而树脂的红外活性, 红外吸收及其对其它 电磁波吸收的特性, 就随时可将这些非可见光的光压信号、温度信号 传递给它。有机树脂不是消极的电气石的载体, 在热力学的方向规定 下,有机树脂参预了电气石的红外发射传输, 高分子材料的众多化合 键的红外活性振动又都处在不停歇的电气石红外能量无阻尼供给中, 从而复合体变成功能的加和体, 倍增体, 这也是实测数值显示膜的红 外性能均超过有机膜和电气石的自身的红外数值的理由所在,负离子 发生数的增加亦如此。
电气石无机 /有机膜是微纳米量子效应的 "永动机"型的生态功 能膜。 6、 许多金属的氧化物、 硫化物、 硒化物、 氟化物在低温时都有 红外发射特征, 每种化合物都有对应的红外波段和主峰位置, 线性光 学系统的可迭加性, 树脂的红外亲和性, 红外活性以及和无机粒子的 相容性, 使电气石在可独自担纲红外发射外, 也可以与其它金属氧化 物组合复配, 既提高红外性又可增加另外所需的附加功能, 使复合材 料膜多功能化, 使膜的红外能谱曲线更完美、 实用。这些金属氧化物 有 A120:!、 Ti02、 Zn0、 Mg0、 Mn02、 Li0、 CuO等, 其中前三个金属氧 化物是半导体性的可用作光触媒抗菌材料的。 前 4. 5 的设计用 Ti02 就基于此。
7、 深度活化和表面改性的电气石能与热塑性树脂如聚乙烯、 聚 丙烯、聚氯乙烯等拉伸成膜,虽然之前有挤压过程但最后是在"张力" 而非"压力"的预应力态下成形的, 因此更适宜生产可降解的功能热 塑膜, 使宝贵的电气石, 沸石最终自动用于土壤的土质改良、 水土保 持。
8、 热固性树脂成膜要有温度、 有压力, 适宜和电气石组合成预 应力型挤压态膜并适于粘附在其它凝聚态材料表面或独立成材。如三 聚氰胺甲醛树脂(MF)与电气石的热固膜, 除生态功能外, 膜的表面 硬度, 耐磨性适宜在木质材料表面作耐磨装饰层用, 此外的热固性树 脂(聚合物)还有聚酯树脂, 呋喃树脂, 聚硅氧垸, 烯丙基酯, 聚氨 酯。这些树脂成膜中的自身内应力不论是体积的、 分子取向的都对电 气石的压敏激发态势有利, 长效、 长寿。
9、 电气石门第高贵, 古作 "碧玺", 回归自然的价值观使电气石 与天然树脂、 天然油漆的结合受人青睐。 因为它们可以更贴近人、 贴 近生活。 如按下述配方, 刷除、 擦涂、 喷涂于木制品如木梳, 丝制品 如 "荷包"则将电气石光量子场、 负离子场带入人身固有的温度场, 电磁场, 表现为天籁的人文关爱可深至皮肤内层, 利于养生保健。
漂白虫胶 55g 松节油 2g
蓖麻油 0. 6g 酒精 7g
红丹 55g 备用酒精 50g
先将虫胶用酒精慢溶几小时后,使用前加其它组份快搅, 使用中 胶稠则用酒精稀释, 膜, 透明, 有弹韧性。
10、 微纳米电气石组 8微米一 4微米; 4微米一 1微米; 亚微米 一纳米; 纳米 1一 100nm。 都能使膜表面在显微意义上成为凹凸不平、 岛屿遍布的"放大"表面,有利于膜表面上红外辐射、有利各种物理、 化学反应的进行,在希望膜的厚度位于细胞尺度的下限而更有益于人 体时(人体对 2. 5— 16微米红外波都有辐射、 吸收, 在 4'微米处皮肤 有强吸收峰, 以这个波长为膜的基本厚度也恰为长波红外 16微米的 1/4, 这是光学增透的最佳尺度。)实用价值的 4微米电气石膜则依赖 各类别功能高分子材料, 功能高分子材料的生物材料的合成开发, 如 电气石口腔牙釉膜, 电气石富氧分离膜。 (直接生产负氧离子)。 但 4 微米膜用紫外光固化的光敏树脂来实现是比较理想和现实的。
不论是粘液态的还是粉末态的光敏树脂加工出来的膜比热塑型 的热固型的相应膜都有更多的优点, 彼如用: 电气石为无机物主料, 光敏树脂用聚氨酯丙烯酸酯为有机物主料,加有机主料必须的稀释单 体, 用 TPGDA、 HDDA或 TMPTA都可以, 紫外光引发剂彼如用 1一羟基 环已基苯乙酮, 各适量混搅碾压成膜。 紫外光辐射源用 2KW水银灯, 辐射距 7cm, 固化时间 15— 30秒, 膜厚光学测量达 3. 8微米。 实测 负离子发生量 Q值为 2. 5万个 /cm:i。 这个膜可以自持, 也可两面夹持 其它功能薄体材料如电热膜, 也可直接粘附在玻璃、木材、 塑料表面 上。
光敏树脂的预应力碾压成膜, 接之紫外光固化的优点有: a膜表 面比表面积大, 粗糙有度, 利于红外辐射。 b、 包括紫外光固化的粉 末光敏树脂能生产出超薄的均匀膜 (2— 4微米) 和异形膜这是其它 如热塑性的热固性的树脂难以作到的。 c、 它是绿色技术产品, 对环 境友好, 成膜的组份完全反应, 无溶剂, 有利于环境保护。 d、 只需 热固化树脂固化能量的 1/3, 压力的 1/10— 100时间的 1%— 1%。就可 以成膜。 e、 各种功能化的单体、 聚合物(低聚物), 光引发剂在国内 已工业化配套生产, 便于组织实施。 f、 紫外光固化的碾压膜, 电气 石和高分子长链、支链、技链是在滚动缠绕中完成物理化学复合的较 之热塑膜的拉伸张力膜更有利电气石功能的发挥,也比热固化的膜硬 度更大, 更耐磨且阻燃并可以对膜的性能需要有再塑造的可能。
在电气石应用的庞大领域中, 电气石无机 /有机超薄膜是改善人 类生存质量, 有比较优势的节约而又高效的一种应用物质形态。
