1、PTC材料
1、PTC material
導(dǎo)電聚合物在發(fā)熱用途上由其具有的正溫度系數(shù)（簡稱PTC），這一非普遍的現(xiàn)象所決定。其主要特性是在細(xì)小的溫度范圍內(nèi)，電的阻抗會有相當(dāng)大的轉(zhuǎn)變。
PTC材料屬于導(dǎo)電高分子復(fù)合材料。將導(dǎo)電粒子如CB分散到高聚物產(chǎn)品中即可制成上述電聚合物。這一特點來于聚合物受熱膨脹的系數(shù)不同，聚合物在升溫或熔解時體積會膨脹，特別在溫度升至熔點的始點時，部分結(jié)晶體開始熔解引致體積明顯增大。這些改變導(dǎo)致了凝結(jié)的CB之間進(jìn)一步的分開。換言之，便切斷了部分導(dǎo)電通道；因而阻礙了電子在CB聚合物組織中的流通，使其阻抗率增大。由此可見，熱線的功率主要受控于傳熱過程，與被加熱體系的溫度有關(guān)；當(dāng)被加熱體系溫度接近于芯帶的溫度時，傳熱幾乎停止，功率趨近于零，實際上停止了加熱，反之亦然。
本所產(chǎn)品之一的電阻（功率）——溫度曲線（見圖一）
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?zé)峋€的工作原理將PTC材料均勻地擠塑在二根或多根平行金屬線芯之間即可得到芯帶。因PTC材料是導(dǎo)體的，所以在芯帶外面還需要包覆一層絕緣材料做為護(hù)套，便得到實用的基本型熱線（見結(jié)構(gòu)圖）。
熱線的金屬線芯接通電源后，電流由一根線芯經(jīng)過跨接于二線之間的發(fā)熱體（PTC材料），到另一線芯而形成回路，電能使發(fā)熱體升溫，其電阻隨即增加，當(dāng)芯帶溫度升到某值之后，電阻已大到幾乎阻斷電流的程度，發(fā)熱體的溫度便不再升高。與此同時，芯帶能過護(hù)套向溫度較低的被加熱體系傳熱，單位時間傳遞的執(zhí)度等于電功率。另一方面?zhèn)鹘y(tǒng)的恒功率加熱器不受被加熱體系溫度的影響，始終提供差不多恒定的功率，一直到被加熱體系散熱速率等于電功率時才停止升溫。
因此，控（限）溫加熱的方式是讓熱線適應(yīng)被加熱體系，而恒功率加熱方式是被加熱體系去適應(yīng)去適合加熱器，這是二者根本的區(qū)別。
這種熱線的實際優(yōu)點是：
（1）熱線絕不會給自身發(fā)出的熱量燒毀，即使體系隔熱十分良好。
（2）熱線相應(yīng)被伴熱體系具有自動調(diào)節(jié)功率的功能，所以在很多應(yīng)用上，其本身即為很好的恒溫加熱器。
（3）特殊的結(jié)構(gòu)已使熱線使用長度達(dá)1000米，故適應(yīng)長輸遠(yuǎn)距離控制及復(fù)雜特殊條件的應(yīng)用。（如石油熱采工藝配套）。
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?zé)峋€參數(shù)
3、Auto-control heating cable data
熱線具有低壓電纜所要求的基本特性。如：絕緣性，物理機械性，抗老化性等。此外，作為并聯(lián)式控（限）溫加熱器，還有它的參數(shù)。熱線的品種不同，參數(shù)也不同。
（1）功率——溫度特性
該特性是模擬管道伴熱保溫條件下測定的。由功率—溫度特性圖（見圖一）可見，隨機系溫度的增加，功率大致呈線性下降，其斜率為體系溫度每改變一度時熱線功率的減少量，它反映了功率隨溫度自動調(diào)節(jié)的能力。應(yīng)當(dāng)指出，熱線的功率是穩(wěn)定態(tài)參數(shù)，影響的因素較多，不能簡單地用電阻乘以電壓加以計算。
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）維持溫度
用熱線伴熱某一體系，若單位時間內(nèi)熱線向體系傳遞的熱量等于體系向環(huán)境傳遞的熱量，體系的溫度便得以維持不變。顯然用功率較大的熱線或體系隔熱較好時，維持溫度較高。能使體系得以維持的溫度稱為“維持溫度”。在使用中，如果設(shè)計得當(dāng)，可以使體系維持溫度到環(huán)境溫度之間的任何溫度。
（3）承受溫度
熱線能承受低于一定溫度的外部熱源的影響，高于此溫度后，功率會緩慢下降而且是積累性的。因此，使用中不要超過熱線的承受溫度。本參數(shù)是選擇熱線的主要參數(shù)之一。
（4）表面溫度
在隔熱良好的密閉容器內(nèi)放入足夠長度的熱線，在額定電壓下達(dá)到溫度為熱線的表面溫度。這一參數(shù)對有易燃物料或有的場合是重要的、
（5）使用長度
熱線可以任意剪短使用，但只能在一定長度范圍內(nèi)任意接長；換言之，不得超過使用長度。使用長度與定額電壓、功率規(guī)格及使用時環(huán)境溫度有關(guān)。如果要求使用的長度超過熱線的使用長度 、應(yīng)當(dāng)另接電源或使用特殊規(guī)格的特長型熱線。
(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、自控溫電伴熱技術(shù)的優(yōu)點 9、Advantage of auto-control temperature
heating technology
1、全自動控制的發(fā)熱功能：
自控：熱能根據(jù)環(huán)境（介質(zhì)）溫度，自調(diào)發(fā)熱量。
節(jié)能：只提供所需要的熱量；扁平外形能與管壁緊密貼合，導(dǎo)熱效率可達(dá)90%以上。
2、安裝靈活，安全可靠：
靈活：熱線具有柔軟性，適合用于復(fù)雜管路等，施工簡便，可靈活的纏繞或平行敷設(shè)在需要伴熱的管件上，自控溫特性使其可重疊使用而不會局部過熱或燒壞；并聯(lián)電阻原理，施工時可按現(xiàn)場需要剪截長度，或采用兩通，三通做接合。
安全可靠：檢測簡易，適用于危險區(qū)，防爆區(qū)和防腐區(qū)。
3、產(chǎn)品壽命特長：
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:
（產(chǎn)品采用高檔原材料，的制造工藝，成品經(jīng)加速成器輻照交聯(lián)處理嚴(yán)謹(jǐn)?shù)纳a(chǎn)規(guī)格要求和嚴(yán)格的質(zhì)量控制體系。）
試驗室加速老化測試推算，產(chǎn)品具有20年以上的壽命。
廣泛應(yīng)用于石油、化工、鋼鐵、煤氣、制冷等行業(yè)的眾多場合，有10年以上現(xiàn)場使用史。
4、自控溫電伴熱技術(shù)具有以下優(yōu)點：
達(dá)到相同的伴熱效果，其耗能量為蒸汽伴熱的1/5-1/4，為恒功率的1/3-1/2；
產(chǎn)品使用壽命特長，是恒功率電阻伴熱的5倍以上；
安裝簡單快捷，成功率高，安裝費是蒸汽伴熱的1/5；
管理容易，沒有日常維修或更換零件的需要，不污染環(huán)境。
低溫時有較高的發(fā)熱量，及時彌補較大的熱損失；高溫時能自動調(diào)低發(fā)熱量，達(dá)到節(jié)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.
