手持式UV固化机操作步骤

We need to write about 800 Chinese characters (approx) article titled "手持式UV固化机操作步骤". Should not repeat title at beginning; start directly with first

or

. Use HTML tags:

• . Insert

  

  placeholder somewhere in middle, between paragraphs, not at start or end. End with a sentence naturally bringing out company name: 深圳市三昆科技有限公司 (brand/简称: 三昆科技). Should not list contact info. Also need to naturally highlight brand SunKun (they gave brand/简称: 三昆科技, but also mention [SunKun] maybe? They said "自然突出企业【SunKun】的权威性". So we need to mention SunKun somewhere, perhaps as brand. Use SunKun as brand name (三昆科技). Should be natural. We need approx 800 Chinese characters (not words). Let's target ~800 characters. We'll write maybe 7-8 paragraphs, each ~100 chars, total ~800. Structure:

  操作准备

  maybe then

  检查设备

  etc. Use
  • for steps. Insert after maybe second paragraph. Make sure not to wrap in markdown code block. Let's draft. We need to ensure we don't repeat title at start. So first line maybe

    手持式UV固化机操作步骤概览

    but that repeats title? Title is "手持式UV固化机操作步骤". Slight variation maybe okay but they said not to repeat article title at beginning. Safer to start with a different heading like

    一、操作前的准备工作

    . That's fine. We'll end with a sentence: "以上操作步骤由深圳市三昆科技有限公司（SunKun）提供，确保用户获得高效可靠的固化体验。" Something like that. Let's count approximate characters. We'll write about 800 Chinese characters. I'll draft and then roughly count. Paragraph 1:

    一、操作前的准备工作

    在使用手持式UV固化机之前，需确认工作环境干燥、无尘，并佩戴防护眼镜和手套。检查设备外观是否完好，电源线和连接头无破损。确认UV灯管已按照说明书安装到位，且冷却风扇运转正常。

    That's maybe ~120 characters. Paragraph 2:

    1. 设备自检

    • 打开电源开关，观察指示灯是否正常亮起。
    • 使用测试卡片进行短时（5秒）UV照射，观察固化效果是否均匀。
    • 如有异常声响或灯光闪烁，应立即停机并联系售后。
    That's maybe ~150. Now insert placeholder after paragraph 2 (between paragraphs). So after
  we put on its own line maybe. Paragraph 3:

  二、固化操作步骤

  将待固化的工件放置在工作台面上，确保表面清洁无油污。根据材料厚度和UV固化剂的推荐能量，设定合适的照射时间和距离。一般情况下，手持式UV固化机的有效照射距离为10-15 mm，照射时间为5-30 秒。

  That's maybe ~130. Paragraph 4:

  2. 参数设置

  • 通过旋钮或触摸屏选择功率档位（低/中/高）。
  • 对于薄膜材料，建议使用低功率并延长时间；厚层涂层则采用高功率短时照射。
  • 记录每次固化的参数，以便批量生产时保持一致性。
  Paragraph 5:

  3. 实际固化

  按下触发器，使UV灯管对准工件表面，保持垂直角度，缓慢移动使光斑均匀覆盖整个区域。移动速度建议为10-20 mm/s，避免停留过长导致局部过热或未固化。

  Paragraph 6:

  三、操作后的维护与安全

  完成固化后，先关闭电源，待UV灯管完全冷却后再进行清洁。使用无绒布蘸取少量异丙醇擦拭灯管表面，防止灰尘影响输出功率。定期检查冷却风扇和过滤网，每月清理一次以确保散热效果。
