style="font-size:14px"><strong>自限温<strong>电伴热带</strong></strong></span>是（国外称为：自控温<span style="font-size:14px"><strong><strong>电伴热带</strong></strong></span>）新一代一种恒温带状电加热器，其发热原件的电阻率具有很高正温系数，在生产过程中，以两根低电阻率、高导电系数、耐腐抗氧化材料为导电母线，在两根电母线之间均匀放置以导电碳粒为发热基材的具有正温度系数的纳米发热聚和物，在每根伴内，母线之间的电路数温度的变化而变化，当<span style="font-size:14px"><strong><strong>电伴热带</strong></strong></span>周围环境温度变低时，发热聚和物微分子收缩而使碳粒连接形成电路，电流通过此电路做功，使<span style="font-size:14px"><strong><strong>电伴热带</strong></strong></span>发热，当温度升高时，发热聚和物微分子膨胀而使碳粒连接渐渐分开，形成的电路数减少，<span style="font-size:14px"><strong><strong>电伴热带</strong></strong></span>自动降低功率输出，当<span style="font-size:14px"><strong><strong>电伴热带</strong></strong></span>周围环境温度变低时，发热聚和物微分子收缩而使碳粒连接又形成电路，这样周而复始控制的温度不会过高亦不会过低，形成温度自动控制。</p><p>二、DBR<strong>-</strong><strong>30-</strong><strong>220-</strong>PJ防护型(低温)<span
