透明二氧化钛(TiO2)浆料是一种具有较大表面积体积比的可见透明浆料。浆料中TiO2纳米颗粒的平均直径为20nm,每一印刷层的透明烧结膜厚度大约为6-7μ米。
应用
TiO2浆料会形成丝网印刷膜,主要作为铟锡氧化物(ITO)或氟掺杂氧化锡(FTO)基衬底上的导电带,用于染料敏化太阳能电池和主要光伏应用。在需要具有较大表面积/体积比的透明烧结二氧化钛薄膜的应用中使用透明二氧化钛膏。当使用 43T 筛网印刷时,配制透明二氧化钛浆料,以获得厚度为 6-7 μm 的烧结薄膜。透明二氧化钛糊剂具有高度分散和稳定的锐钛矿纳米颗粒。它的优化丝网印刷使用一个合成的 43T 网状网(或类似的)。干燥后,该糊剂必须在 500°C 或 500°C 以上温度下烧结。当使用 43T 筛网时,得到透明烧结层;一个打印层膜厚度约为 6-7 μm,两个打印层膜厚度约为 12 μm。该糊剂表现出最佳的流变属性,提供了良好的表面均匀性,并含有特别配制的有机粘合剂,以提供适用于一系列染料/电解质系统的通用多孔性。保存:20°C 避光保存
Transparent titania (TiO2) paste is a visual range transparent paste that has a large surface area to volume ratio. The average diameter of the TiO2nanoparticle within the paste is 20nm and the transparent sintered films are around 6-7 μm thick per printed layer.Use Transparent Titania Paste in applications that require a transparent sintered titania film with a large surface/volume ratio.Transparent Titania Paste is formulated to yield sintered film thicknesses of 6-7μm when screen printed with a 43T mesh. Transparent Titania Paste has highly dispersed and stable anatase nanoparticles.It is optimised for screen printing using a synthetic 43T mesh screen (or similar). After drying; this paste must be fired at or above 500°C. This results in a transparent sintered layer; with a film thickness of approximately 6-7μm for one printed layer and ~12μm for two printed layers; when using a 43T mesh screen.The paste exhibits optimal rheological properties that provide good surface uniformity and contains organic binders specially formulated to provide versatile porosity suitable for a range of dye/electrolyte systems.Storage: Store in the dark at 20°CTiO2paste forms a screen printed film which is majorly used as a conduction band on indium tin oxide (ITO) or fluorine doped tin oxide (FTO) based substrates for dye sensitized solar cells and for major photovoltaic based applications.
