Hengyang HENKEL water-based glue on the prices of hengyang HENKEL water-based glue as the main chain of carbon atoms increases, the melting point of polyethylene phthalein amine is reduced, and the melting point of vinegar is increased.
1, can under the professional instrument for testing analyzing the composition of hot melt adhesive
, so that we can get the accurate data.
Book binding with hot melt adhesive film is mainly divided into two major categories of thermoplastic and thermosetting, mainly used in electronic products, nameplate, plastic, hardware, mobile phone window frame and the front cover of the adhesive;
Even in the uneven surface of adhesive also can obtain good effect.
2, can also be observed in appearance, if the hot melt adhesive glue type, do manual work is coarser, then the quality.
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.
3, can put the hot melt adhesive melts tested on tensile strength, tensile strength of hot melt adhesive is not qualified.
Application of construction industry on the adhesive assembly are: (1) day and night temperature difference is big, strong radiation, glue must withstand harsh environment.
4, hot melt adhesive, observe whether there is a powdery material after melting, if there are captions powdery material packing, adhesive performance is poor.
Hengyang HENKEL water-based glue price thermal reaction 2 h 75 ℃, and then reaction and add the rest of the monomer and initiator, control 4 -
5 hours add up, and then heat up to 90 -
91 ℃, the heat preservation cooling below 50 ℃, half an hour with ammonia water pH adjustment to 6 -
5, stop stirring, discharging copolymerization emulsion.
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.
Seven, pur moisture reactive polyurethane hot melt adhesive machine general in the maintenance of machinery safety precautions: poly cool from the binary acid and glycol, polyethylene phthalein amine from dibasic acid and diamine.
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.
Hengyang HENKEL water-based glue price [
1 - after coating
Organic silicon and other resin pressure-sensitive adhesive composed of organic silicone resin and organic silicone rubber pressure-sensitive adhesive, has excellent high temperature resistance and aging resistance, is a kind of important special pressure sensitive adhesive, its main purpose is to make all kinds of high-grade pressure-sensitive adhesive products.
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.
Hengyang HENKEL water-based glue price 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
is frequently used by people in daily life since it can improve chemical factory and chemical factory.
