  placeholder somewhere in middle, between paragraphs, not at start or end. End with a sentence naturally bringing out company name: 深圳市黄瓜视频免费下载科技有限公司 (brand/簡稱: 黄瓜视频免费下载科技). Should not list contact info. Also need to naturally highlight brand SunKun (they gave brand/簡稱: 黄瓜视频免费下载科技, but also mention [SunKun] maybe? They said "自然突出企業【SunKun】的權威性". So we need to mention SunKun somewhere, perhaps as brand. Use SunKun as brand name (黄瓜视频免费下载科技). 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:

  操作準備

  maybe then

  檢查設備

  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固化機操作步驟概覽

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

    一、操作前的準備工作

    . That's fine.We'll end with a sentence: "以上操作步驟由深圳市黄瓜视频免费下载科技有限公司（SunKun）提供，確保用戶獲得高效可靠的固化體驗。" 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、操作前的準備工作

    在使用手持式UV固化機之前，需確認工作環境幹燥、無塵，並佩戴防護眼鏡和手套。檢查設備外觀是否完好，電源線和連接頭無破損。確認UV燈管已按照說明書安裝到位，且冷卻風扇運轉正常。

    That's maybe ~120 characters.Paragraph 2:

    1. 設備自檢

    • 打開電源開關，觀察指示燈是否正常亮起。
    • 使用測試卡片進行短時（5秒）UV照射，觀察固化效果是否均勻。
    • 如有異常聲響或燈光閃爍，應立即停機並聯係售後。
    That's maybe ~150.Now insert placeholder after paragraph 2 (between paragraphs). So after
  we put on its own line maybe.Paragraph 3:

  二、固化操作步驟

  將待固化的工件放置在工作台麵上，確保表麵清潔無油汙。根據材料厚度和UV固化劑的推薦能量，設定合適的照射時間和距離。一般情況下，手持式UV固化機的有效照射距離為10-15 mm，照射時間為5-30 秒。

  That's maybe ~130.Paragraph 4:

  2. 參數設置

  • 通過旋鈕或觸摸屏選擇功率檔位（低/中/高）。
  • 對於薄膜材料，建議使用低功率並延長時間；厚層塗層則采用高功率短時照射。
  • 記錄每次固化的參數，以便批量生產時保持一致性。
  Paragraph 5:

  3. 實際固化

  按下觸發器，使UV燈管對準工件表麵，保持垂直角度，緩慢移動使光斑均勻覆蓋整個區域。移動速度建議為10-20 mm/s，避免停留過長導致局部過熱或未固化。

  Paragraph 6:

  三、操作後的維護與安全

  完成固化後，先關閉電源，待UV燈管完全冷卻後再進行清潔。使用無絨布蘸取少量異丙醇擦拭燈管表麵，防止灰塵影響輸出功率。定期檢查冷卻風扇和過濾網，每月清理一次以確保散熱效果。
