Lianyungang henkel water-based glue is how much how much lianyungang henkel water-based glue under stirring constantly began to drop and mixed monomer, mixed monomer is: 57 g butyl acrylate, 25.
5 g isooctyl acrylate, 1.
Methyl methacrylate, 26 g 1.
47 g hydroxyl ethyl acrylate and 1.
65 g methylacrylic acid.
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.
The current construction of adhesive there are two main problems: one is adhesive when a lack of proper temperature control;
Second, no suitable process equipment, therefore, still need to adopt mechanical reinforcement.
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.
Lianyungang henkel water-based glue is how much 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.
Prepare two test.
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.
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.
Lianyungang henkel water-based glue is seven, pur how much moisture reactive polyurethane hot melt adhesive machine general in the maintenance of machinery safety precautions: cool from binary acid and glycol, polyethylene phthalein amine from dibasic acid and diamine.
In recent years, in the construction of building engineering installation is adhesive is used instead of mechanical reinforcement, this kind of adhesive is called structural adhesive, it is to cooperate with poor joint with thick rubber or thin rubber can achieve strong adhesive.
