表面改性
经表面改质
forming a slurry of a surface-modified particulate inorganic material in an aqueous medium
在水性介质中形成表面改性粒子无机材料之浆液;
Moy does not contemplate the use of surface-modified particles, not the use of cross-linkers to form the capsule wall.
Moy未考虑使用表面改性粒子,亦未使用交联剂来形成胶囊壁。
Cross-linkers are compounds that have at least two reactive groups that will react with the reactive groups on the surface-modified particles.
交联剂係具有至少两种反应性基团之化合物,该等反应性基团将与位于经表面改质粒子上之反应性基团反应。
Meanwhile, extra water was added to a surface-modified Kaolin dispersion prepared according to Example 1 and then to this dispersion, the SolvessoTM 200ND plus SuprasecTM 5025 solution was added dropwise with mixing by a YstralTM high shear mixer operated at about 5000rpm.
The results showed that (1) appropriately acid-treated and surface-modified honeycomb cordierite can be used as support for monolithic catalysts
研究结果表明,蜂窝状堇青石经酸适当处理及表面改性后,可用作整体式催化剂的栽体;
Tungsten trioxide thick film surface modification: Acid decomposition; adding a binder to obtain a tungsten trioxide sensitive material slurry; print slurry on the interdigital electrode and a silver electrode silver wire alumina substrate, air heat sintering; carry out a thermal insulation of the gas sensor respectively under H2 and air atmosphere to produce a surface-modified WO 3 thick film gas sensors.
dispersing the solution into the slurry to form a Pickering emulsion and causing or allowing the cross-linker to react with the surface-modified particulate inorganic material so as to form a cross-linked microcapsule wall.
The surface-modified particles were then added to water and dispersed with an Ultrasonic Probe (Sonics and Materials, Vibra CellTM, with microtip - hereinafter referred to as an Ultrasonic Probe) operated under the following conditions: 50% Duty cycle; Output Control 4; for 6 minutes.
随后将该等经表面改质粒子添加至水中并使用超音波探针(Sonics and Materials, Vibra CellTM,具有微尖端-下文称作超音波探针)于下述条件下作业来实施分散处理:50%工作循环;输出控制4;持续6分钟。
The present invention relates to a new process for making microcapsules which does not require surfactant and which provides microcapsules having an increased, relatively high level of protection from u.v. light for the contents; the present invention involves the use of surface-modified particulate inorganic material to form microcapsule walls where a cross-linker is used to react with the surface-modified material such that each microcapsule wall is a cross-linked wall.
The present invention discloses a surface-modified europium photoelectrode and the preparation method.
本发明公开了一种表面修饰铕的三氧化钨光电极及制备方法。
A microcapsule comprising an encapsulated material surrounded by a wall, characterised in that the wall comprises a particulate inorganic material that has been surface-modified and cross-linked.
一种微胶囊,其包含藉由壁包围之囊封材料,其特征在于该壁包含已经表面改质及交联之粒子无机材料。
Typically, when the particulate inorganic material is surface-modified so as to have amine groups on its surface and the cross-linker is a polyisocyanate, stirring the dispersion at between 15 and 25oC for an hour is sufficient to complete the reaction.
This Example illustrates the preparation of a surface-modified clay dispersion.
该实例阐释表面改质黏土分散液之制备。
