Qingdao industrial adhesive industry complaints

Qingdao industry industrial rubber industry of Qingdao industrial glue of complaint environmental protection, high efficiency, low cost, simple process of the development of the reactive flame retardant has great prospects for development. Use hot melt adhesive sealing speed, the bonding process only need 1 ~ 3 seconds to complete, suitable for mass production, less energy consumption, low cost. Standard corrugated carton sealing of hot melt adhesive costs about 32 1000 yuan/box, this is the middle of the hot melt adhesive price, and tape seal in the middle of the price is about 120 yuan / 1000 cases. At the same time, under the certain condition of constant temperature heating for a period of time, the chromaticity and salary increase a certain range. Other applications are rectifying device and honeycomb sandwich plate edge from the pressure seal joint. If use hot melt adhesive, highly processed adhesive will not cause downtime; While replacing tape need downtime. And, in the box is not installed clapboard, sealing strength is greater than that of using tape sealing with diaphragm sealing intensity, can reduce the cost of diaphragm. 2, polyurethane hot melt adhesive machine, when to take off the bucket, filling the air pressure should be from small to large pressure slowly, under no circumstances do not allow direct use of high pressure gas directly to take off the barrel, avoid the accident. In addition to using conventional adhesive parts structure adhesive, due to the ship sailing in the special environment, lake and sea, also use large amounts of adhesive/sealant to seal, liquid polysulfide sealant used for filled structure joint, so as to solve the joints airtight problem by wood swelling. The choice of the hot melt adhesive: Qingdao industry industrial gel complaints which polyacrylate is used much, its production has more than natural rubber pressure-sensitive adhesive. At present, the domestic do adhesive manufacturers have thousands of home, in front of the interests of many businesses shoddy, and hot melt adhesive with different affinity of different adhesive materials. In order to make better play to the 'sticky' hot melt adhesive, adhesive industry experts warm reminder, when choosing hot melt adhesive should carefully consider the following factors: the characteristic with chemical resistance and easy repair. 1) Healthy environmental protection: inferior hot melt adhesive often USES recycled materials or inferior raw material, or in the process of the system of plastic formation pollution, or process defect cause gum is not pure, hot melt adhesive containing solvents prone to make finished products or impurity moisture or easy to volatile substances. For the food industry, are lethal damage. Qingdao industry industrial glue complaint hot melt adhesive machine of softening degree requirements at 80 ~ 90 ℃. In the process of heating for a long time, do not produce adhesive solution change color, in use process surface crust. ( 1) Adjust the structure under the premise that guarantees the stability of the emulsion, the content of hydrophilic group as low as possible, can improve the water resistance of the film; These series of products used in automobile electronic components, fixed component adhesive, filling and sealing, which can effectively improve the seismic resistance of products. Note product features appearance milky white or light yellow latex adjust the indicators, this product according to the laminating process when using, do not add water or other solvents work to maintain good health habits 20 kg, 50 kg bottled product features look milky emulsion (2) resin pressure-sensitive adhesive used this kind of pressure sensitive adhesive resin of polyacrylic acid ester, pu, PVC, polyvinyl ether, etc. 2) Color: by the color of the adhesive material is different, color requirements for hot melt adhesive should differ. If it be adhesive content itself to the color no special requirements, it is recommended to use yellow hot melt adhesive, generally speaking, yellow hot melt adhesive is better than white sticky. Qingdao industrial adhesive industry complaints [ 2] Performance measurement requirements type editor CS501 super constant temperature trough, D25 - Type electric mixer, speed controller, oven, balance, three flask, drip tube, thermometer, beaker, measuring cylinder, pipette, washing ears ball, Fourier infrared spectrometer in spite of the existing reactive flame retardant effect is limited, but the reactive acrylate pressure-sensitive adhesive performance still has a lot of advantages in various aspects, flame retardant pressure sensitive adhesive huge market for its research and development also brings a lot of power. Thus directly affect the printing, composite cost.
