Jilin HENKEL sealing glue equipment jilin HENKEL sealing glue 2 test preparation.
In unit mixer, constant pressure drop funnel, reflux condenser and the 250 ml of the thermometer three flask, add 2.
Ethylene alcohol and deionized water 90 g 5 g.
1, can under the professional instrument for testing analyzing the composition of hot melt adhesive
, so that we can get the accurate data.
Five, ink, glue viscosity change with strong read relationships (
Grafting modification right amount of styrene monomer, are added into the polyurethane emulsion by in-situ polymerization of polyurethane grafted styrene emulsion, improves the adhesion
and water resistance.
2, can also be observed in appearance, if the hot melt adhesive glue type, do manual work is coarser, then the quality.
Application of construction industry on the adhesive assembly are: (1) day and night temperature difference is big, strong radiation, glue must withstand harsh environment.
3, can put the hot melt adhesive melts tested on tensile strength, tensile strength of hot melt adhesive is not qualified.
Civil engineering in the construction industry, adhesive is mainly used for structure and decoration, making many engineering components, such as cork plywood, laminated board, laminated board, and some of the same component, plastic floor, carpet, ceramic tiles, wallpaper paste.
4, hot melt adhesive, observe whether there is a powdery material after melting, if there are captions powdery material packing, adhesive performance is poor.
Jilin HENKEL sealing glue equipment both to be near the melting point of polyethylene.
The USES of the products after the equipment clean with clear water, improve the production environment, eliminate oily products combined with process of electrostatic fire accidents, ensure machine stability qualified production personnel health (
3000 r/min, the centrifugal 10 min without precipitation or layered)
Work to maintain good health habits packaging and storage, please do not mix with other products, not finished product should be kept sealed.
EVA hot melt adhesive by basic resin, tackifier and viscosity regulator and antioxidant components, etc.
5, good quality hot melt adhesive with heat resistance performance, can put the hot melt adhesive in zero or more than 40 degrees respectively environment for testing, if there are brittle, soft gelatin said quality is bad now.
Jilin HENKEL sealing glue equipment jilin HENKEL sealing glue mixing and heating, heating to (
℃, polyvinyl alcohol completely dissolved.
Has the very good performance, basic no curing volatiles release.
