615 Bonding Film
jsw-615 bondingfilm instructions: please empty a small section of glue before dispensing.heat melt the jsw3542615 bonding film at a constant temperature of 110 ℃, apply the adhesive to the part to be bonded with thedispensing equipment, complete the bonding within 2 minutes, and maintain thepressure in the fixed tool for 10-20 minutes before moving to the nextposition. it is not recommended to heat each 615 bonding film continuously for more than three hours. the same 615 bonding film cannot be heated threetimes. heating for a long time will make the rear part of the rubber tube touchthe air temperature and form a crust, which can be pierced to reduce the gluepressure.
the above is a brief introduction of 615 bonding film. for detailed data, please go to the downloadwindow of jinshengwei official website. the following is the informalinformation of 615 bonding film forreference only.
thermal aging mechanism of 615 bonding film: two changes occur when the adhesive meets heat:1. physical changes are reversible reactions. linear thermoplastic rubbersoftens and melts, while cross-linked thermosetting rubber produces largedeformation. 2. the chemical changes of 615bonding film are irreversible reactions, mainly thermal decomposition andoxidative decomposition. this is the main reason for the thermal aging of theadhesive. the main temperature parameters characterizing these changes areconstant temperature, thermal deformation temperature, melting point,decomposition temperature, etc. when 615bonding film is heated over, the mechanical strength decreasessignificantly. when the heating temperature reaches the peak, the adhesive willbe permanently damaged and cannot be used. experiments show that moisture isfar more serious than thermal decomposition in curing 615 bonding film. because the moisture is the chemical bondsolidified by 615 bonding film first, the products generated by the solidification reaction will bepermanently invalid and should not be dissolved for use.
to trulyunderstand the brand competitiveness of enterprise 615 bonding film, we must clearly, profoundly and comprehensivelyunderstand the connotation of brand competitiveness at all levels from thetable to the inside. brand marketing capability of 615 bonding film enterprise refers to the brand's over-valueprofit-making capability, which is the external and explicit performance of 615 bonding film enterprise's brandcompetitiveness, compared with competitive brands in the market. enterprisebrand management capability refers to the capability system formed by an enterprisein a series of specific 615 bonding film enterprise brand management activities, including a number of capabilities fromenterprise brand positioning, enterprise brand communication to 615 bonding film enterprise brandoperation.
determination of test environment conditions manyexperiments show that moisture content and temperature of 615 bonding film sample have little influence on its climate aging. 615 bonding film has little changein adhesive strength after aging under high humidity for a certain period oftime, and aging is slower when high temperature and high humidity existsimultaneously. however, the humidity control system of most 615 bonding film test equipment is notperfect or at all. therefore, when the lamp is turned on, the lamp source emitsa large amount of heat energy, causing the ambient temperature to rise, thuscausing the humidity to drop, thus the 615bonding film sample cannot maintain the moisture content in the atmosphereunder normal conditions. if spraying water periodically, the moistureabsorption of 615 bonding film sample does not change much, but the surface temperature decreases. therefore,it is an urgent task to improve the on-site humidity and temperature regulatingdevices. when the temperature cannot be maintained after turning on the light,alternating test method can be adopted to keep the temperature as high aspossible.
