真空浸渍系统KemVac主要用于多孔材料如陶瓷和喷涂,从而加强脆性材料。 对于这种类型的工作,由于其低粘度和低蒸气压,使用环氧树脂。 当与荧光染料混合时,它们可用于孔检测。 真空浸渍是通过将安装座放入钟罩中进行的,该钟罩与管道和连接器连接到真空泵。 真空吸取封装样品的环氧树脂的任何夹带的空气。 移动的空气被环氧树脂替代,提供完整的粘合和支撑。
真空浸渍装置(无压缩空气供应)
真空浸渍系统KemVac设计用于嵌入和浸渍多孔材料。 它从安装材料中除去被捕获的空气,并消除了样品和树脂之间的间隙。

KemVac配备一套用于铸造环氧树脂的用品。
metkon冷安装浸渍装置VACUMET
大多数矿物样品具有孔隙,空洞和裂缝,因此需要在真空下嵌入。 metkon冷安装浸渍装置VACUMET轻松有效地满足了这一要求。 此外,它还可以用于将样品胶合到载玻片上,以进行薄片制备的进一步处理。
需要来自压缩机的正气压
提供一套浇注环氧树脂的用品。 可选的Vacumet消耗品套件(10杯,10个硅胶管,树脂和固化剂)可用。
真空浸渍的使用优点
用树脂包封和/或浸渍样品,特别是柔软,粉状,破裂,脆性,易碎或破裂时,有助于:
(a)填充空隙,孔隙和裂纹;
(b)提高整体的完整性和易于处理;
(c)保留样品中组分和边缘的原始微观结构和分布;
(d)保持粘附到样品的其余部分上的分离的,脱粘合的碎片部分;
(e)制备用于切片,研磨,薄切或抛光的原始碎片或粉末样品的固体块。
封装表明将样品浸入模具中的树脂内以改善脆性,易碎材料的外部完整性,并且用于随后的取样步骤的更好处理,而浸渍指示将液体树脂注入或渗透到多孔样品中以改善其内部作为外部完整性。环氧树脂用于包封和浸渍。环氧树脂的粘度越低,浸渍过程中样品渗透深度越深,与组分的机械结合越好。
Mounting
After cutting the specimen, the next step is mounting. The aim of mounting is to handle small or odd shaped specimens and to protect fragile materials, thin layers or coating during preparation as well as to provide good edge retention. Mounting produces specimens with uniform size so that it is easier to handle in automatic holders for further preparation steps.
Basically, two methods are available:
Hot Mounting
Cold Mounting
In hot mounting, the specimen is mounted under heat and pressure with a hot mounting press.
Cold mounting is preferred for samples which are sensitive to damage from heat and pressure (like coatings, PCB, etc.) Cold mounting resins are easy to use and require mixing which is then poured into a mould and allowed to set.
安装
切割标本后,下一步是安装。安装的目的是处理小或奇怪的标本,并保护脆弱的材料,薄层或涂层在准备过程中,以及提供良好的边缘保留。安装产生均匀大小的试样,以便在自动保持器中更容易操作,以便进行进一步的准备。
基本上,有两种方法可用:
•热安装
•冷安装
在热安装时,试样安装在热和压力下用热安装压力机。
冷安装是*的样品,是敏感的热和压力的损害(如涂料,PCB等)冷安装树脂易于使用,需要混合,然后倒入模具,并允许设置。
VACUMET is designed for embedding and impregnation of porous materials. It removes the trapped air from the mounting material and eliminates the gaps between the specimen and the resin. Most mineralogical specimens have porosities, cavities and cracks and ther fore need to be embedged under vacuum. VACUMET fulfills this requir ment easily and efficiently. In addition, VACUMET can also be used for glueing the specimens on the glass slides for further processing in thin section preparation.
vacumet是专为嵌入多孔材料,浸渍。它从安装材料中除去被困的空气,消除了试样和树脂之间的间隙。大多数矿物标本有气孔、孔洞、裂缝,因此需要embedged真空。vacumet履行这一要求,容易和有效。此外,vacumet也可用于粘合标本玻片在薄片制备进一步处理。
