1、PTC材料

1、PTC material

导电聚合物在发热用途上由其具有的正温度系数（简称PTC），这一非普遍的现象所决定。其主要特性是在细小的温度范围内，电的阻抗会有相当大的转变。

PTC材料属于导电高分子复合材料。将导电粒子如CB分散到高聚物产品中即可制成上述电聚合物。这一特点来于聚合物受热膨胀的系数不同，聚合物在升温或熔解时体积会膨胀，特别在温度升至熔点的始点时，部分结晶体开始熔解引致体积明显增大。这些改变导致了凝结的CB之间进一步的分开。换言之，便切断了部分导电通道；因而阻碍了电子在CB聚合物组织中的流通，使其阻抗率增大。由此可见，热线的功率主要受控于传热过程，与被加热体系的温度有关；当被加热体系温度接近于芯带的温度时，传热几乎停止，功率趋近于零，实际上停止了加热，反之亦然。

本所产品之一的电阻（功率）——温度曲线（见图一）

Conducting polymer has the positive temperature coefficient when heating. The impedance of this material will change greatly within small temperature range.

PTC is a kind of conducting polymer material which is formed by scattering the particles CB to the polymer compound. When the polymer compound is heated, the expansion coefficient is different. Polymer will expanse when in melting or high temperature. Some molecule begins melting and its occupation is bigger which leads the longer distance among the CB particles. The electron flow is partially cut off so the impedance is bigger.

Resistance(watt)-temperature(see fig. 1) of one kind cable.

2、Working principle

自控热线的工作原理将PTC材料均匀地挤塑在二根或多根平行金属线芯之间即可得到芯带。因PTC材料是导体的，所以在芯带外面还需要包覆一层绝缘材料做为护套，便得到实用的基本型热线（见结构图）。

热线的金属线芯接通电源后，电流由一根线芯经过跨接于二线之间的发热体（PTC材料），到另一线芯而形成回路，电能使发热体升温，其电阻随即增加，当芯带温度升到某值之后，电阻已大到几乎阻断电流的程度，发热体的温度便不再升高。与此同时，芯带能过护套向温度较低的被加热体系传热，单位时间传递的执度等于电功率。另一方面传统的恒功率加热器不受被加热体系温度的影响，始终提供差不多恒定的功率，一直到被加热体系散热速率等于电功率时才停止升温。

因此，控（限）温加热的方式是让热线适应被加热体系，而恒功率加热方式是被加热体系去适应去适合加热器，这是二者根本的区别。

这种热线的实际优点是：

（1）热线绝不会给自身发出的热量烧毁，即使体系隔热十分良好。

（2）热线相应被伴热体系具有自动调节功率的功能，所以在很多应用上，其本身即为很好的恒温加热器。

（3）特殊的结构已使热线使用长度达1000米，故适应长输远距离控制及复杂特殊条件的应用。（如石油热采工艺配套）。

Working principle, extrude the PTC material evenly on the two or multi paralleled metal cores to make the core belt. Since PTC material is conductive, so the insulation material is applied outside the core belt.(see structure fig.)

When the power is applied to the cable, the current flows from one core through the PTC to another core. The electric energy heats up the PTC and its resistance increases following the temperature until it is big enough to cut off the current, and the temperature will not go up. In the meantime, the heat is transmitted from the core through the sheath to be object. The heat transmitted is equal to electric power. In this reference, the power of the heating cable is controlled by the transmission process, and related to the temperature of the object. When the object temperature is close to core belt temperature, there is no heat transmission and heating is stopped. On the other hand, the conventional heater provides the constant watt regardless of the temperature of the object, until the heat dissipation is equal to the electric power.

So the main difference of the limit temperature control heating and the constant watt heating is that in the former case, the cable meets the object temperature and in the latter case, the object temperature meets the heating cable.

The advantage of this cable:

(1) The cable will not burn by itself heat, good in heat isolation.

(2) The cable can regulate the output watt automatically as a good constant temperature heater.

(3)The max. usable length is up to 1000m due to its special structure. It is suitable for long-distance under complicated conditions.

3、自控热线参数

3、Auto-control heating cable data

热线具有低压电缆所要求的基本特性。如：绝缘性，物理机械性，抗老化性等。此外，作为并联式控（限）温加热器，还有它的参数。热线的品种不同，参数也不同。

（1）功率——温度特性

该特性是模拟管道伴热保温条件下测定的。由功率—温度特性图（见图一）可见，随机系温度的增加，功率大致呈线性下降，其斜率为体系温度每改变一度时热线功率的减少量，它反映了功率随温度自动调节的能力。应当指出，热线的功率是稳定态参数，影响的因素较多，不能简单地用电阻乘以电压加以计算。

Heating cable has the basic features of the low-voltage cables. Such as insulation, physical and mechanical property, aging features. In addition, as the paralleled limit temperature heater, it has special technical data and specification.

(1)watt-temperature feature

The feature is tested under the mimic pipeline heating conditions. In the watt-temperature feature The feature is tested under the mimic pipeline heating conditions. In the watt-temperature diagram(fig.1), the watt decreases in linear with the increase of the temperature. The vamp of the line is watt decrease per temperature degree, and it reflects the watt regulates with the temperature. The watt of the cable is a stable data, influenced by many factors ,not simple as resistor times voltage.

（2）维持温度

用热线伴热某一体系，若单位时间内热线向体系传递的热量等于体系向环境传递的热量，体系的温度便得以维持不变。显然用功率较大的热线或体系隔热较好时，维持温度较高。能使体系得以维持的温度称为“维持温度”。在使用中，如果设计得当，可以使体系维持温度到环境温度之间的任何温度。

（3）承受温度

热线能承受低于一定温度的外部热源的影响，高于此温度后，功率会缓慢下降而且是积累性的。因此，使用中不要超过热线的承受温度。本参数是选择热线的主要参数之一。

（4）表面温度

在隔热良好的密闭容器内放入足够长度的热线，在额定电压下达到温度为热线的表面温度。这一参数对有易燃物料或有的场合是重要的、

（5）使用长度

热线可以任意剪短使用，但只能在一定长度范围内任意接长；换言之，不得超过使用长度。使用长度与定额电压、功率规格及使用时环境温度有关。如果要求使用的长度超过热线的使用长度、应当另接电源或使用特殊规格的特长型热线。

(2)Max. holding temperature

When using the heating cable, if the heat transmitted to the object is equal to heat transmitted from the object to environment, the temperature of the object is kept constant. It is obviously good to use bigger heating cable or with good heat isolation, the temperature of the object is kept higher. This temperature is called“max. holding temperature” If design is fine, the temperature of the object is kept between the holding temperature and the ambient temperature.

(3) Max. endurance temperature

The heating cable can withstａnd the influence from the outside heat source. The output watt reduces down in accumulative mode. So do not exceed the max. endurance temperature of the cable. This the main data for ion of the cale

(4) Max. surface temperature

Put the enough length of the cable in the sealed container. The max. temperature is called max. surface temperature under the rated voltage. This data is essential in the case of flammable material of gas places.

(5) Max. usable length

The cable can be cut in any length and connected together to a certain length, that is, not exceeding the max. usable length. Max. usable length is related to rated voltage, watt and min. ambient temperature. If it necessary to exceed the max. usable length, additional power supply is applied or special long cable is used.

9、自控温电伴热技术的优点 9、Advantage of auto-control temperature

heating technology

1、全自动控制的发热功能：

自控：热能根据环境（介质）温度，自调发热量。

节能：只提供所需要的热量；扁平外形能与管壁紧密贴合，导热效率可达90%以上。

2、安装灵活，安全可靠：

灵活：热线具有柔软性，适合用于复杂管路等，施工简便，可灵活的缠绕或平行敷设在需要伴热的管件上，自控温特性使其可重叠使用而不会局部过热或烧坏；并联电阻原理，施工时可按现场需要剪截长度，或采用两通，三通做接合。

安全可靠：检测简易，适用于危险区，防爆区和防腐区。

3、产品寿命特长：

1、fully automatic control heating:

Auto-control: the heating is automatically adjusted according to the ambient(media)temperature.

Energy-saving: only provide the needed heat. The flat cable stick to the pipe wall and heating efficiency is up to 90%.

2、Flexible and safe in installation

Flexible: The heating cable is flexible and suitable in complicated pipelines and easy in laid-up.

The cable can wrap or lay out on the pipelines. The cable can be overlapped without burning due to its auto control of temperature. The cable can be cut in any length or connected together in two three stripes.

Safe: It is easy to test and suitable in dangerous, explosive and erosive areas.

3、Long lifetime:

（产品采用高档原材料，的制造工艺，成品经加速成器辐照交联处理严谨的生产规格要求和严格的质量控制体系。）

试验室加速老化测试推算，产品具有20年以上的寿命。

广泛应用于石油、化工、钢铁、煤气、制冷等行业的众多场合，有10年以上现场使用史。

4、自控温电伴热技术具有以下优点：

达到相同的伴热效果，其耗能量为蒸汽伴热的1/5-1/4，为恒功率的1/3-1/2；

产品使用寿命特长，是恒功率电阻伴热的5倍以上；

安装简单快捷，成功率高，安装费是蒸汽伴热的1/5；

管理容易，没有日常维修或更换零件的需要，不污染环境。

低温时有较高的发热量，及时弥补较大的热损失；高温时能自动调低发热量，达到节能的效果。

(The product is made of firt-class material under advanced workmanship, subject to radiation cross-link treatment, abiding the requirements and strict quality control system.)

The lifetime is more than 20 years by the accelerated aging in the lab.

The product is used in petrol-chemical, steel works, gas, cooler-making more than 10 years.

4、The auto-control temperature heating technology has the following advantages:

The energy consumption is 1/5-1/4 of the steam heating, 1/3-1/2 of the constant watt heating to reach the same heating effect.

The life-time is 5 times longer than constant resistor heating.

The installation cost is 1/5 of the steam heating.

Easy in maintenance without replacement of the parts, and not pollution to the environment.

At low temperature it can release more heat to compensate loss.

At high temperature it can reduce the heat release to save energy.
