Hot melt adhesive for navigator

详情描述：

The modified solid-state jsw-Hot melt adhesive for navigator is a kind of cross-linked structural adhesive with high adhesive strength. It has good fluidity when heated and is easy to coating It has the characteristics of fast melting by heating and high strength adhesive force by curing with moisture in the air. It can meet the bonding requirements of structural parts of mobile electronic products Hot melt adhesive for navigator is suitable for bonding base materials: ABS, PMMA, polycarbonate (PC), PS, glass products, acrylic, UV coating, polyester (including DCPD modification), aluminum alloy (better anode treatment), nickel chromium coating (rough surface) and other materials or mutual bonding Jsw-Hot melt adhesive for navigator is one component, 100% solidified, solvent-free, pollution-free and toxic. Resistant to water, oil and acid Fast curing, easy to wet, high adhesion and high strength. It has stable performance, excellent toughness and filling property after curing.
The above is a brief introduction of Hot melt adhesive for navigator. For detailed data, please go to the download window of jinshengwei official website. The following is the informal information of Hot melt adhesive for navigator for reference only.
It is best to make standard test pieces by using Hot melt adhesive for navigator bonding, and go through the same technological process as the adhered parts. The standard test piece shall be designed for the test method that can represent the loading requirements of the main structure. For example, if the main parts are subjected to tensile shear under normal conditions, the test piece shall be designed as lap shear. After Hot melt adhesive for navigator is cured, cracks or defects can be found through inspection of joint parts. This inspection method can be destructive or non-destructive. Destructive tests are generally conducted by subjecting Hot melt adhesive for navigator test pieces in the production process to simulated accelerated application conditions, and determining whether Hot melt adhesive for navigator has the same performance as the test pieces with known bonding performance and good application performance. Reasons for some defects found in mechanical tests (failure tests) and elimination methods.
The -NCO group in isocyanate is easy to react with compounds containing active hydrogen. The main chemical reaction formula is as follows: 615 -NCO group in hot melt adhesive and water or other active hydrogen compounds. The main reaction formula is as follows: OCN-OCN 2 HOHOOCHN R NH-COOH (1). The isocyanate group in Hot melt adhesive for navigator continues to react with the carbamate generated in the formula (1) to generate allophanate: -NCO -NHCO (Bu-N (C0NH) COO (2) The allophanate group generated in the formula (2) continues to react with the isocyanate group to generate biuret Hot melt adhesive for navigator structure: Nitcoh NCO ... NC (Conh) Onh (3), wherein the carbamate link (-NHCOO-), urea link (-N HCONH-) are highly polar, and Hot melt adhesive for navigator forms rigid link of polyurethane molecular structure. Hot melt adhesive for navigator uses polyester, diisocyanate, aliphatic molecular mass regulator containing 4-14 sulfur atoms, catalyst, polymerization inhibitor, etc. to prepare one-component moisture-curing polyurethane Hot melt adhesive for navigator for shoes with peel strength of 10kN/m, softening point of 40-70℃, and curing time of 2-20 min.
However, there are many enterprises struggling in Hot melt adhesive for navigator. After more than ten years of development in this industry, everyone thinks that we are all in Hot melt adhesive for navigator high-tech industry. However, for us, there are also traditional industries and emerging industries in this small industry. We think that hot melt adhesive is a traditional industry, and wet curing Hot melt adhesive for navigator belongs to the new generation, so today I focus on researching and developing Hot melt adhesive for navigator product innovation. Because today's mobile phones and tablets are more and more integrated with Hot melt adhesive for navigator. Four years ago, in order to emphasize the changes brought about by our smart phones, everyone has accepted their own smart phones today. Is there anyone else using traditional phones now? Therefore, four years ago, I thought that 80% of digital products would be applied to Hot melt adhesive for navigator. JSW not only developed products, but actually made products for the market.
