    • PURPOSE: A method for staining granite is provided to improve the resistance of color against light, to prevent the elution of color in water and to enhance acid or alkali resistance. CONSTITUTION: A method for staining granite comprises trimming the surface of the cut stone material; washing it with water; firstly heating it in an electric furnace and cooling it in vacuum; dipping it in an oxalic acid (CH3COOH) solution for 12 hours and treating it with hydrochloric acid to dissolve the iron distributed in the stone material; secondly heating it gradually to 200 deg.C in vacuum; dipping the cooled one in a paint of 40~60°C for 24~48 hours; mixing the stone material with a polymer such as urethane, silicone, etc. together a pigment by using a polymeric ceramics nano-silica or nano alumina sol-gel, a ceramic bead or polymer sphere, to permeate the pigment into the stone material; dipping it at a curing agent of 60°C for 24 hours; and washing it with water.
    • 目的:提供一种花岗岩染色方法,以提高颜色对光的抵抗力,防止色素在水中的溶出,提高耐酸碱性。 构成:花岗岩染色方法包括修剪切割石材表面; 用水冲洗; 首先在电炉中加热并在真空中冷却; 将其浸入草酸(CH 3 COOH)溶液中12小时,用盐酸处理,溶解分布在石材中的铁; 其次在真空中逐渐加热至200℃; 将冷却后的样品浸入40〜60℃的涂料中24〜48小时; 通过使用聚合物陶瓷纳米二氧化硅或纳米氧化铝溶胶 - 凝胶,陶瓷珠或聚合物球将石材与聚氨酯,硅氧烷等聚合物混合在一起,以将颜料渗透到石材中; 将其浸入60℃的固化剂中24小时; 并用水冲洗。

    • PURPOSE: A method for manufacturing a ceramic tag antenna of a multiband RFID system is provided to receive a plurality of frequency signals by integrating an RFID frequency band antenna and an ISM(Industrial Scientific Medical) band antenna. CONSTITUTION: A ceramic tag antenna receives two different frequency signals at the same time. The ceramic tag antenna includes a first frequency antenna and a second frequency antenna. A first frequency antenna receives the signal with 900MHz band. The first frequency antenna has a first dielectric substrate. A second frequency antenna receives the signal with 2.6GHz band. The second frequency antenna has a second dielectric substrate. The first and second dielectric substrates have different dielectric constants.
    • 目的:提供一种用于制造多频带RFID系统的陶瓷标签天线的方法,通过集成RFID频带天线和ISM(工业科学医学)频带天线来接收多个频率信号。 构成:陶瓷标签天线同时接收两个不同的频率信号。 陶瓷标签天线包括第一频率天线和第二频率天线。 第一个频率天线接收900MHz频带的信号。 第一频率天线具有第一电介质基板。 第二个频率天线接收2.6GHz频带的信号。 第二频率天线具有第二电介质基板。 第一和第二电介质基片具有不同的介电常数。
