To identify the quality of the heat shrinkable casing must know 3 elements
set research and development, production, sales in a body, providing cable terminal head custom, cable connector, cable terminal head, shrinkage cable accessories, cable head, heat shrinkable cable accessories, cable accessories and other products, by AnWei power below small make up to introduce you to distinguish the quality of the heat shrinkable casing must know 3 elements:
to distinguish the quality of the heat shrinkable casing must know of 3 points, the first thing to do - — Definition. Heat shrinkable casing to identify first you have to know what is the heat shrinkable casing. Heat shrinkable casing is usually made from polyolefin heat shrinkage of new composite tubular materials. Segment if there are many kinds of heat shrinkable casing, my company production PE heat shrinkable tube only other manufacturers may also produce PVC casing or iron fluoride walk-on tube and so on. Heat shrinkable casing wall thickness varies with the diameter of the. Then, because of the expansion process of heat shrinkable casing contraction ratio also have different ( Regular is contraction twice) , our heat shrinkable sleeve is generally two times the adhesive heat shrinkable tube of contraction ratio can reach three times four times.
to understand what the heat shrinkable tube, the next step is to identify the quality of the heat shrinkable casing must be know the second of three elements: - — Material characteristics. It has introduced the main raw material is polyolefin heat shrinkable casing, polyolefin heat shrinkable casing is also one of the very common, using temperature Min da 55 Max 125, so a wide range of temperature conditions in combination with heat shrinkage characteristics make it widely used in military rail and air, and many other industries. And heat shrinkable casing has all sorts of color, the color of the standard are red, green, yellow and black white yellow green double color and transparent, so many colors to make heat shrinkable tube can be applied to all sorts of color of wires and wire connection.
the next step is to identify the quality of the heat shrinkable casing must know the three elements of the third point - — Scope of application. Because of the above two factors, and the characteristics of the soft environmental protection performance is stable, PE heat shrinkable casing is widely applied in electrical wire connection, protection of the solder joint, and electronic components anticorrosive protective insulation treatment and related products, etc. If you were to be used outdoors suggest using black heat shrinkable casing, because generally other color uv resistance of the heat shrinkable casing will be slightly a little bit weak black last much longer.
as a good procurement staff must master this distinguish of three elements: the quality of the heat shrinkable casing must be know, such ability in the present good and evil people mixed up of cable accessories in the market to buy good heat shrinkable tube.
