大多數礦物樣品具有孔隙,空洞和裂縫,因此需要在真空下嵌入。 metkon冷安裝浸漬裝置VACUMET輕松有效地滿足了這一要求。 此外,它還可以用于將樣品膠合到載玻片上,以進行薄片制備的進一步處理。
真空浸漬系統KemVac主要用于多孔材料如陶瓷和噴涂,從而加強脆性材料。 對于這種類型的工作,由于其低粘度和低蒸氣壓,使用環氧樹脂。 當與熒光染料混合時,它們可用于孔檢測。 真空浸漬是通過將安裝座放入鐘罩中進行的,該鐘罩與管道和連接器連接到真空泵。 真空吸取封裝樣品的環氧樹脂的任何夾帶的空氣。 移動的空氣被環氧樹脂替代,提供完整的粘合和支撐。
真空浸漬裝置(無壓縮空氣供應)
真空浸漬系統KemVac設計用于嵌入和浸漬多孔材料。 它從安裝材料中除去被捕獲的空氣,并消除了樣品和樹脂之間的間隙。

metkon冷安裝浸漬裝置VACUMET
大多數礦物樣品具有孔隙,空洞和裂縫,因此需要在真空下嵌入。 metkon冷安裝浸漬裝置VACUMET輕松有效地滿足了這一要求。 此外,它還可以用于將樣品膠合到載玻片上,以進行薄片制備的進一步處理。
需要來自壓縮機的正氣壓
提供一套澆注環氧樹脂的用品。 可選的Vacumet消耗品套件(10杯,10個硅膠管,樹脂和固化劑)可用。
真空浸漬的使用優點
用樹脂包封和/或浸漬樣品,特別是柔軟,粉狀,破裂,脆性,易碎或破裂時,有助于:
(a)填充空隙,孔隙和裂紋;
(b)提高整體的完整性和易于處理;
(c)保留樣品中組分和邊緣的原始微觀結構和分布;
(d)保持粘附到樣品的其余部分上的分離的,脫粘合的碎片部分;
(e)制備用于切片,研磨,薄切或拋光的原始碎片或粉末樣品的固體塊。
封裝表明將樣品浸入模具中的樹脂內以改善脆性,易碎材料的外部完整性,并且用于隨后的取樣步驟的更好處理,而浸漬指示將液體樹脂注入或滲透到多孔樣品中以改善其內部作為外部完整性。環氧樹脂用于包封和浸漬。環氧樹脂的粘度越低,浸漬過程中樣品滲透深度越深,與組分的機械結合越好。
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.
安裝
切割標本后,下一步是安裝。安裝的目的是處理小或奇怪的標本,并保護脆弱的材料,薄層或涂層在準備過程中,以及提供良好的邊緣保留。安裝產生均勻大小的試樣,以便在自動保持器中更容易操作,以便進行進一步的準備。
基本上,有兩種方法可用:
•熱安裝
•冷安裝
在熱安裝時,試樣安裝在熱和壓力下用熱安裝壓力機。
冷安裝是*的樣品,是敏感的熱和壓力的損害(如涂料,PCB等)冷安裝樹脂易于使用,需要混合,然后倒入模具,并允許設置。
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是專為嵌入多孔材料,浸漬。它從安裝材料中除去被困的空氣,消除了試樣和樹脂之間的間隙。大多數礦物標本有氣孔、孔洞、裂縫,因此需要embedged真空。vacumet履行這一要求,容易和有效。此外,vacumet也可用于粘合標本玻片在薄片制備進一步處理。
