according to Customized Woven belt According to the functional data learned by Xiao Bian, the temperature of the lit cigarette is about 700 ℃, and the continuous burning time of a cigarette is about 15 minutes, which is a long time. Gongzhuling Woven belt However, the spontaneous ignition point of common combustibles is very low, such as paper, cotton, linen and knitted fabrics, whose ignition point is mostly 200 ℃ to 300 ℃, so it is easy to cause fire. Turning to the statistics of major and catastrophic fires nationwide, there are many records of fires and casualty accidents caused by smoking after drinking, smoking in bed, littering cigarette butts and other reasons. The typical case is the Great Khingan Mountains forest fire in 1987, which caused a heavy loss of 6.913 billion yuan. It was later discovered that four of the first five fire spots of the fire were caused by human beings, and two of the fire spots were ignited by the cigarette butts of three "smokers".
Here are some examples of the production process of radio lanyard, toy lanyard, flashlight lanyard and camera lanyard. 1. Wholesale of webbing: nylon, pp, polyester and high elastic cotton are generally used to make lanyards, and the general specifications are 4mm, 5mm, 6mm, 7mm, 8mm, 10mm, 12mm, 16mm, 20mm and 25mm wide. 2. Accessories: general accessories include metal clasps, certificate clips, etc., and plastic ones include aircraft clasps, plug buckles, safety buckles, etc. 3. Assembly: first print, cut according to the specified size, add string, plastic buckle, glue or press metal sheet, and then package. After inspection, a lanyard can be shipped in this way.
The application of is already very common, and the technology is also new one by one. Let's talk about it briefly from the manufacturer's editor. I hope it can help. It is well known that it has been widely used. Now many bag webbing manufacturers are constantly upgrading their products to make our life more convenient. Knitting can not only weave belts, but also weave ropes. Tubular belt is a kind of braided rope. Rope or rope with a diameter of 1~4 cm is also called rope. Rope with a diameter of more than 4 cm is also called rope. Rope with a diameter of more than 40 cm is generally called cable or rope.
Under normal use, the general use time is about three years. After three years, because of natural wear, part of the pp webbing will be corroded and broken. But this is under normal use. If it is not used frequently, similar situations will not occur. The reason why most of them cannot be used for such a long time is because they are lost in advance rather than because of other external damage. Therefore, the advice of Xiaobian is not to worry too much about the service life of the PP webbing, but to pay attention to how to protect yourself from loss and trouble.
The tensile strength after light treatment, the natural light shines on the bag webbing through the window, causing aging and reducing its strength. According to the working conditions, a lighting equipment is designed, which is equipped with representative strong light and is exposed to the light for a specified time. After lighting, pp webbing needs to be subjected to standard temperature and humidity treatment, and then to tensile test to obtain the tensile strength after lighting treatment. After soaking, the tensile strength of the safety belt installed in the car will absorb the moisture in the air, and sometimes it will be soaked by some liquid, so the immersion test is required. At room temperature, fully immerse in distilled water with a small amount of wetting agent for a specified time, and then take out the soaked pp webbing from the water to complete the tensile test within 10 minutes. The tensile strength of soaked pp webbing was obtained.
Guess the pros and cons. It is difficult to identify the front and back sides of some cases and bags because of their special texture. The following is how the luggage and webbing factory teaches you to identify the front and back of the webbing. In fact, we can identify it according to the pattern of the webbing, the front of the pattern is clear and clean, the pattern lines are obvious, the layers are clear, and the color is bright. Generally, the patterns on the front are clearer and more beautiful than those on the back. The front pattern of plant and color matching patterned fabrics with striped appearance must be clear and pleasing. This pattern is especially obvious when weaving jacquard belts.
