style="font-family: 微軟雅黑, "Microsoft YaHei"; font-size: 16px;">1.當(dāng)單頭<a href='http:///' target='_blank' class='key_tag'><font color=#2086ee><strong>加熱管</strong></font></a>用于加熱容易熔化金屬或固體的硝鹽、石蠟、瀝青等物質(zhì)時，應(yīng)先熔化加熱物質(zhì)，以降低單頭加熱管的外部電壓，熔化后恢復(fù)到額定電壓。此外，單頭加熱管加熱硝鹽等容易發(fā)生爆炸事故的物質(zhì)時，應(yīng)充分考慮安全措施。</span></p><p style="line-height: 2em; text-indent: 2em;"><span style="font-family: 微軟雅黑, "Microsoft YaHei"; font-size: 16px;">2.單頭加熱管用于空氣加熱時，應(yīng)注意單頭加熱管的均勻排列。這樣做的好處是保證單頭加熱管有充足均勻的散熱空間，盡可能保證空氣的流動性，提高單頭加熱管的加熱效率。</span></p><p style="line-height: 2em; text-indent: 2em;"><span style="font-family: 微軟雅黑, "Microsoft YaHei"; font-size: 16px;">3.氧化鎂填充在單頭加熱管內(nèi)部的間隙中，單頭加熱管出線端的氧化鎂砂容易因雜質(zhì)和水分的滲入而受到污染。因此，操作時應(yīng)注意單頭加熱管出線端的狀態(tài)，避免漏電事故。</span></p><p style="line-height: 2em; text-indent: 2em;"><span style="font-family:
