, huaian, huaian boss laminating adhesive contact boss laminating adhesive contact stirring edge heating, heating to (
℃, polyvinyl alcohol completely dissolved.
1, can under the professional instrument for testing analyzing the composition of hot melt adhesive, so that we can get the accurate data.
EVA hot melt adhesive by basic resin, tackifier and viscosity regulator and antioxidant components, etc.
2, can also be observed in appearance, if the hot melt adhesive glue type, do manual work is coarser, then the quality.
3, can put the hot melt adhesive melts tested on tensile strength, tensile strength of hot melt adhesive is not qualified.
EVA hot melt adhesive is a kind of without solvent, excluding water solid meltability polymer;
It is solid at room temperature, heat can melt to a certain temperature to flow, and has a certain viscosity liquid.
4, hot melt adhesive, observe whether there is a powdery material after melting, if there are captions powdery material packing, adhesive performance is poor.
Huaian boss laminating adhesive contact with the increase of the main chain of carbon atoms, the melting point of polyethylene phthalein amine is reduced, and the melting point of vinegar is increased.
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.
Both are 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.
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.
Huaian boss laminating adhesive contact 5, pur hot melt adhesive machine, when to take off the bucket, the way is to five gallons of hot melt adhesive in barrel filling the dry nitrogen, avoid using not dry compressed air directly, if you need filling the compressed air, it is necessary to thoroughly dry compressed air.
Color: brown 2.
Soft, good elasticity, resistance to kink deformation;
Product category editing epoxy resin type: single-component or bi-component, for the majority of base material has good bonding properties, resistance to chemicals.
Huaian boss laminating adhesive contact adhesive assembly building industry applications are: (1) day and night temperature difference is big, strong radiation, glue must withstand harsh environment.
There is a strong need for more research on , in order to be able to provide strong and conclusive evidence of their chemical factory effects. However, recent studies have provided valuable insights into how the intake of may result in improved chemical factory.
