Our front-line sales partners often encounter some new contacts, with customer friends of the hot shrink tube consultation, with what shrink heat shrink tube? How about the heat shrink tube heater? Can my hair dryer be used as a heat shrink tube heater? Which tool is suitable for single-wall heat shrink tubes, double-wall heat shrink tubes, medium-thick wall heat shrink tubes, or special heat shrink tubes, such as silicone rubber heat shrink tubes, teflon heat shrink tubes, PVDF heat shrink tubes and other special heat shrink tubes? Next, I'll give a brief introduction to how to popularize heating knowledge of heat shrink tubes.

First of all, the mechanical drive hot air furnace heating tube heating method.

This type of heating is often used in some harness enterprises to process heat shrink tubes in large quantities. After all, the heating tool for this heat shrink tube is also expensive and is not suitable when using the heat shrink tube in small batches. Mechanical drive-type hot air drying tube heat shrink tube heat shrink tube heating characteristics: generally used for small single-wall heat shrink tube or double-wall heat shrink tube, composed of fans and heat exchangers, suitable for large-scale production.

Second, the use of hot air gun heating tube heating

The characteristics of the heating and shrinking tube of the hot air gun: manual heat shrink tool, simple operation, suitable for low demand for heat shrinkage, low yield, high experimental situation, high-end hot air gun products have a controlled temperature model.

3. Heat the shrink tube in the oven or oven.

It is common practice to use the above two ovens to heat the bus heat shrink tube and medium thick wall heat shrink tube, and it is also a heating method more suitable for small and medium-sized large-size heat shrink tubes.

Four, flame (torch) oven gun heating

The use of flame guns is generally common in outdoor work, such as outdoor pipe anti-corrosion heat shrink sleeve installation is the most common use of this flame gun heating industry. For example, small partners in our production department also use flame guns to heat the hot shrink tubes of the female row when processing and manufacturing the female row connector boxes.

V. Other heating tools

In addition to the above heat shrink tube heating tools, there are alternative heat shrink tube heating tools such as lighters, electric heating wire, heated boiling water, home hair dryers, alcohol spray lamps, iron and other alternative heat shrink tube heating tools.

Heating method of heat shrink tube

The heat shrink tube is a polymer alloy made from a mixture of high-quality polymers and made by scientific formulations and machinery. The product is formed by the electronic accelerator irradiation crosslinking and continuous expansion. Products with soft, flame retardant, rapid shrinkage, widely used in wire connections, welding spot protection, wire end, harness and electronic components protection and insulation treatment, wire pole identification and other products.

We usually have three ways to heat the shrink tube: a lighter, a hot air gun, and an oven. The lighter is a convenient and commonly used tool for heating the shrink tube, but its temperature is as high as 1000 degrees, which is much higher than the shrinkage temperature of the heat shrink tube. Therefore, when we use the lighter, we must pay attention to move back and forth so that the heat shrink tube can be heated evenly as a whole. To prevent the heat shrink tube from burning out, it does not make the shape of the heat shrink tube very ugly. However, in reality, we tend not to control the temperature of the lighter easily burn the heat shrink tube, so we recommend the use of professional heating tools.

1. Hot air gun heating is a professional tool, heating gun heating method: open the heating gun, warm up the entire section of the copper rod requiring a retractable sleeve. The heating should be uniform so that the temperature of the copper rod is higher than the ambient temperature, which is about 60 degrees C.

2. Place the proper lying sleeve on the copper row and wear protective gloves when operating to avoid scaling the copper chops. The heating gun is applied to heat the copper drain heat shrink tube and is heated slowly and evenly from one end to the other or from the middle to the end. Heating from both ends to the middle is strictly prohibited to avoid the appearance and expansion of bubbles. When there is a bend when heating, the inner bend should be heated first, and then the outer bend should be heated to avoid the folding of the copper drain heat shrink tube at the bend. When heating, the heating gun should be moved evenly, so that the casing heating uniform, but the local temperature can not be too high, resulting in the heat shrink tube burning or sticky cold phenomenon. At the end of the heating, after cooling the copper rod, according to the "bus manufacturing and assembly process specifications" requirements, the use of electric knives to pull out the copper drain heat shrink tube mating position, pull the sleeve, the force should not be too large, so as not to damage the copper row. After processing, if there are stains on the surface of the heat shrink tube, apply an alcohol cloth to wipe.

3. Heat shrink tube heating, in the heating oven, pay attention to the layout is uniform, do not pile together, so as to avoid the above problems.

Turn on the oven, set the temperature at around 60 c to 70 degrees C, preheat the whole object with a heat shrink tube for 5 minutes, remove the heated object from the oven, cover the proper length of the heat shrink tube, and wear protective gloves during operation to avoid burns. According to the copper-drained heat shrink tube manufacturer, after selecting the right temperature and heating time, heat the copper drain heat shrink tube in the oven, be careful not to squeeze too much copper in the oven. In order to avoid the pressure generated by the copper drain heat shrink tube when the heat shrink effect is not good, at the end of the heating, after cooling the copper rod with an electric knife, the copper drain heat shrink tube is pulled out of the mating place in accordance with the "bus manufacturing and assembly process procedure". When pulling out the casing, the force should not be too large, so as not to damage the copper rod, after processing, if the copper pipe surface stains, apply a cloth cleaning (impregnated solvent, if necessary, does not affect the insulation performance of the casing).

热缩管加热工具推荐

我们的一线销售伙伴经常会遇到一些新的接触，与客户朋友的热收缩管咨询，用什么收缩热缩管？热缩管加热器怎么样？我的吹风机能用作热收缩管加热器吗？哪种工具适用于单壁热收缩管、双壁热收缩管、中厚壁热收缩管、或者特种热收缩管，如硅橡胶热收缩管、铁氟热收缩管、PVDF热收缩管等特殊热收缩管？接下来，我将简单介绍一下如何普及热收缩管的加热知识。

一、首先，机械驱动热风炉加热管的加热方式。

这种加热方式在一些线束企业中经常被用来大量加工热收缩管。毕竟，这种热收缩管的加热工具也是昂贵的，在小批量使用热收缩管时也不太合适。机械传动式热风干燥管热收缩管的加热方式特点：一般用于小型单壁热收缩管或双壁热收缩管，由风机和换热器组成，适用于大型生产。

二、使用热风枪进行热缩管加热

热风枪加热收缩管的特点：手动热收缩工具，操作简单；适用于热收缩需求低、产量低、实验性强的场合；高端热风枪产品有数控温度模型。

三、使用烤箱或烤箱加热收缩管。

采用上述两种烘箱对母线热收缩管和中厚壁热收缩管进行加热是比较普遍的做法，也是一种更适用于中小批量大尺寸热收缩管的加热方法。

四、火焰（炬）烘枪进行热缩管加热

火焰枪的使用一般在户外工作中较为常见，如室外管道防腐蚀热收缩套筒的安装是使用这种火焰枪加热行业中最常见的。例如，我们生产部门的小伙伴在加工制造母排接头盒时，也使用火焰枪加热母排的热缩管。

五、其它加热工具

除了上述热收缩管加热工具外，还存在诸如打火机、电加热丝、加热开水、家用吹风机、酒精喷灯、烙铁等可替代的热收缩管加热工具。

热缩管的加热方法

热缩管是以优质聚合物为原料，经科学配方和机械共混而成的聚合物合金。该产品是通过电子加速器辐照交联和连续膨胀形成的。产品具有柔软,阻燃,迅速萎缩,广泛应用于电线连接、焊点保护、线端、线束及电子元器件的保护和绝缘处理、电线杆的标识等产品。

我们通常有三种加热收缩管的方法：打火机、热气枪和烤箱。打火机是加热收缩管的一种方便和常用的工具，但其温度高达1000度，远高于热收缩管的收缩温度。因此，当我们使用打火机时，我们必须注意来回移动，这样热收缩管就可以作为一个整体均匀加热。为了防止热收缩管燃烧出来，也不会使热收缩管的形状变得很难看。然而，在现实中，我们往往无法控制打火机的温度容易烧毁热收缩管，所以我们推荐使用专业的加热工具。

1。热风枪加热是一家专业工具，加热枪加热方法：打开加热枪，预热整段需要热缩套的铜棒。加热应均匀，使铜棒的温度高于环境温度，约为60 ℃。

2。将适当长度的套管放在铜排上，操作时戴好防护手套，以免烫伤铜排。加热枪应用于加热铜排热收缩管，从一端到另一端或从中间到两端缓慢而均匀地加热。严禁从两端加热至中间，以避免气泡的出现和膨胀。当加热时有弯曲处时，应先加热内弯，然后再加热外弯，以避免弯曲处铜排热缩管的折叠。加热时应均匀移动加热枪，使套管加热均匀，但局部温度不能过高，造成热缩管烧焦或粘冷现象。在加热结束时，冷却铜棒后，根据“母线制造及装配工艺规范”的要求，使用电刀拉出铜排热收缩管的搭接位置，拉拔套管时，受力不宜过大，以免损坏铜排。加工后，如果热收缩管表面有污渍，应用酒精布擦拭。

3.热收缩管加热，在加热烤箱时，要注意布局均匀，不要堆放在一起，以免出现上述问题。

打开烤箱，将温度设定在60℃~70℃左右，用热收缩管预热整个物体5分钟；将加热物体从烤箱中取出，盖上适当长度的热收缩管，在操作过程中戴上防护手套，以避免烫伤。根据铜排热收缩管制造商提供的信息，在选择合适的温度和加热时间后，用烤箱加热铜排热收缩管，注意烘箱中的铜排不要挤压过大。为了避免铜排热缩管在热收缩效果不好时产生的压力，在加热结束时，用电刀将铜棒冷却后，按照“母线制造和装配工艺规程”，将铜排热收缩管拔出搭接处。拔出套管时，力不应过大，以免损坏铜棒；加工后，如果铜管表面有污渍，应用抹布清洗(浸渍溶剂，必要时不影响套管绝缘性能)。
