Waterproof double-wall heat shrinkable tube outer coating made of high quality cross-linked polyolefin material, the inner layer of hot melt adhesive composite processing. The outer layer with insulation, corrosion, wear, etc., inner layer has a low melting point, waterproof sealing and mechanical strain cushioning performance advantages. Waterproof glue double-wall heat shrink tubing is widely used in electronic equipment wiring waterproof seal leak gas, at a fixed wire branch, corrosion protection, metal wire and cable repair pipelines in the wiring of the pump and submersible pumps can also be used to waterproof glue double-wall heat shrink tubing.
Recently more and more customers to inquire case waterproof double-wall heat shrinkable tube, there are a lot of these customers are shipbuilding or ship parts manufacturers, of which there are a number of shipyards specialist had come to visit our company. Through conversations with these customers, probably understand some cases they actually use, such as a military ship repair factory to visit our company, they buy back the main heat-shrink tubing is used for marine cable repair. Today browse an on-site problem analysis shipbuilding article, occasionally seen some use waterproof double-wall heat shrink tube handle instances of the actual situation, to share with you here.
Shipbuilding in the presence of such a problem: marine navigation lights lighting system, lights system prone insulation is low, the article's author is a very experienced shipbuilding engineer, he analyzed the main reasons for this situation, where references about his analysis of the original words "cap at the end due to the cable wiring handle the lighting is not good (such as the difference between the inlet and finally with fiberglass pipe quality) caused by moisture in the rain; countermeasures as long as the terminals insulated handle (as with thermoplastic pipe or high-quality insulation sleeves), improve lighting tightness. "here as a professional manufacturer of heat shrinkable tube, it is necessary for him to make a correction, or a so-called high-quality thermoplastic pipe insulation sleeves should be heat shrinkable tube, marine shrink tube, there is a name in the waterproof glue or double-wall heat shrink tubing heat shrink tubing. This is mainly because the internal tube coated with a layer of hot melt adhesive process, when the heat shrink tubing heat shrink, hot melt adhesive also be melted, so the packing seal the culvert, etc. have a role.
There is a problem later also added author mentions, navigation lights and other lights except low lighting insulation construction technology is not in place, some manufacturers of a product defect can not be ignored. For example: the lamp lead insulation is not good (good insulation performance when vacant, the touch lamp outlet ¿×ʱÃ÷ significantly reduced); fixture junction box or the smaller space, terminal and junction box cover too close causing the insulation is reduced. The double-wall heat shrink tubing through the water treatment can be solved, but virtually to the installation and commissioning of the unit adds a lot of extra work. Of course, waterproof double-wall heat shrink tubing to the author of this word is my goodwill replaced.
Today we are Seeing through these two very simple small example can be seen: waterproof double-wall heat shrink tubing is mainly used for insulation protection. Of course, the role of the ordinary to achieve the same heat shrinkable tube, choose waterproof double-wall heat shrink tubing is mainly caused due to environmental requirements insulation, heat shrink tube, hot melt adhesive excellent waterproof sealing effect in marine equipment to get the perfect expression.
Finally, I hope there is an expert in ship manufacturing wing after seeing this article, we interact, discuss waterproof double-wall heat shrink tubing and other shipbuilding industry shrinkable materials application status and application prospects.
