The above is a brief introduction of 615 Hot Glue. For detailed data, please go to the download window of jinshengwei official website. The following is the informal information of 615 Hot Glue for reference only.
The molecular weight (or polymerization degree) of 615 Hot Glue of polymer directly affects the intermolecular force of polymer, while the intermolecular force of 615 Hot Glue determines the melting point and boiling point of substance, and the glass transition temperature Tg and melting point Tm of polymer. Therefore, whether polymer is used as 615 Hot Glue or as adherend, its molecular weight affects the bonding strength. The relationship between molecular weight and bonding strength of 615 Hot Glue is limited to the case of unbranched linear polymer. Cohesive failure of 615 Hot Glue occurs in the whole range of molecular weight. At this time, bonding strength increases with the increase of molecular weight, but remains unchanged when molecular weight reaches a certain value.
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 615 Hot Glue 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 615 Hot Glue structure: Nitcoh+NCO ... NC (Conh) Onh (3), wherein the carbamate link (-NHCOO-), urea link (-N HCONH-) are highly polar, and 615 Hot Glue forms rigid link of polyurethane molecular structure. 615 Hot Glue uses polyester, diisocyanate, aliphatic molecular mass regulator containing 4-14 sulfur atoms, catalyst, polymerization inhibitor, etc. to prepare one-component moisture-curing polyurethane 615 Hot Glue for shoes with peel strength of 10kN/m, softening point of 40-70℃, and curing time of 2-20 min.
This is also the best platform for displaying innovative 615 Hot Glue products. We will invite many product managers, entrepreneurs, 615 Hot Glue experts and scholars in the industry to recommend 615 Hot Glue products with the most innovative spirit from different perspectives. According to the selection rules, we will finally issue the 2013 China 615 Hot Glue Innovation Enterprise List from ten dimensions including technology research and development, product function, commercial system, production design, appearance and image, dissemination and promotion, 615 Hot Glue product positioning, customer service, marketing channels, organization and management. At the same time, we will select the top three innovative products in China in 2013 from the three categories of science and technology, manufacturing and service.
