<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><strong style="color: blue;"> <span style="color: black;">1、</span>胶带剥离法</strong></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">胶带剥离法是最直观、最简单的油墨附着牢度测试<span style="color: black;">办法</span>之一。其操作<span style="color: black;">过程</span>如下：</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">1. 准备<span style="color: black;">周期</span>：<span style="color: black;">首要</span>，<span style="color: black;">选取</span>一段与印刷品材质相近的标准胶带，<span style="color: black;">保证</span>其粘性适中，不会因过强而损坏印刷品表面，<span style="color: black;">亦</span>不会因过弱而<span style="color: black;">没法</span>有效剥离油墨层。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">2. 粘贴与剥离：将胶带平整地粘贴在待测油墨区域上，<span style="color: black;">保证</span>胶带与油墨表面充分接触，无气泡或褶皱。<span style="color: black;">而后</span>，以恒定且适中的速度将胶带从印刷品表面<span style="color: black;">快速</span>剥离。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">3. 观察与<span style="color: black;">评定</span>：剥离后，仔细观察油墨表面<span style="color: black;">是不是</span><span style="color: black;">显现</span>脱落、剥离或变色现象。若油墨层完好无损，则说明附着牢度良好；反之，则<span style="color: black;">显示</span>附着牢度不足。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><strong style="color: blue;"> <span style="color: black;">2、</span>百格刀切割法</strong></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">百格刀切割法<span style="color: black;">经过</span>模拟微小区域的<span style="color: black;">理学</span>破坏来<span style="color: black;">评定</span>油墨的附着牢度，适用于多种材质表面的测试。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">1. 切割网格：<span style="color: black;">运用</span>标准的百格刀在待测油墨区域上切割出纵横交错的网格，网格<span style="color: black;">体积</span><span style="color: black;">一般</span>为1mm×1mm或2mm×2mm，<span style="color: black;">保证</span>切割深度到达但不超过油墨层下的基材。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">2. 胶带测试：在切割好的网格上粘贴一段标准胶带，<span style="color: black;">根据</span>胶带剥离法的<span style="color: black;">过程</span>进行剥离。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">3. 评级：<span style="color: black;">按照</span>剥离后网格内油墨的脱落<span style="color: black;">状况</span>，进行评级。<span style="color: black;">一般</span>，评级标准分为0-5级，其中0级<span style="color: black;">暗示</span>油墨完全脱落，5级<span style="color: black;">暗示</span>油墨无脱落或仅边缘有轻微剥离。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><strong style="color: blue;"> <span style="color: black;">3、</span>摩擦<span style="color: black;">实验</span>法</strong></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">摩擦<span style="color: black;">实验</span>法<span style="color: black;">经过</span>模拟<span style="color: black;">平常</span><span style="color: black;">运用</span>中的摩擦磨损过程，<span style="color: black;">评定</span>油墨的耐摩擦性能。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">1. 设备准备：<span style="color: black;">运用</span>专业的摩擦<span style="color: black;">实验</span>机，设定合适的摩擦压力、速度和时间参数。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">2. 样品<span style="color: black;">安置</span>：将待测印刷品固定在<span style="color: black;">实验</span>机上，<span style="color: black;">保证</span>测试区域平整无褶皱。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">3. 进行摩擦：<span style="color: black;">起步</span><span style="color: black;">实验</span>机，让摩擦头在油墨表面进行往复摩擦。摩擦次数和力度可<span style="color: black;">按照</span><span style="color: black;">实质</span>需要进行<span style="color: black;">调节</span>。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">4. 观察结果：摩擦结束后，<span style="color: black;">检测</span>油墨表面<span style="color: black;">是不是</span><span style="color: black;">显现</span>磨损、褪色或剥离现象，以<span style="color: black;">评定</span>其附着牢度。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><strong style="color: blue;"> <span style="color: black;">4、</span>溶剂擦拭法</strong></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">溶剂擦拭法利用特定溶剂对油墨的溶解<span style="color: black;">功效</span>，<span style="color: black;">评定</span>油墨在特定溶剂环境下的附着牢度。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">1. 溶剂<span style="color: black;">选取</span>：<span style="color: black;">按照</span>油墨类型和基材特性，<span style="color: black;">选取</span>合适的溶剂。<span style="color: black;">平常</span>的溶剂有酒精、丙酮、甲苯等。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">2. 擦拭操作：<span style="color: black;">运用</span>浸有溶剂的棉球或纱布，在待测油墨区域轻轻擦拭数次。<span style="color: black;">重视</span><span style="color: black;">掌控</span>擦拭力度，避免过度施力<span style="color: black;">引起</span>基材<span style="color: black;">损害</span>。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">3. 观察<span style="color: black;">评定</span>：擦拭后，观察油墨表面<span style="color: black;">是不是</span><span style="color: black;">显现</span>溶解、褪色或剥离现象。若无<span style="color: black;">显著</span>变化，则说明油墨在该溶剂环境下的附着牢度较好。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><strong style="color: blue;"> <span style="color: black;">5、</span>气候老化<span style="color: black;">实验</span>法</strong></p>
