Xiaogan production packaging glue direct xiaogan production packaging glue direct 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.
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.
Hot melt adhesive observe whether there is a powdery material after melting, if there is a powdery material specification packing, adhesive performance is poor.
With heat resistance performance, good quality hot melt adhesive, you 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.
So, over the past 20 years, this kind of pressure sensitive adhesive is developing very rapidly, and have replaced the dominance of natural rubber pressure-sensitive adhesive.
Because the effects of solvent is solvent resin or additives, additives, etc. , given to liquidity make the ink, glue easily distracted.
At present good quality hot melt adhesive can be used in the field of industrial manufacturing, heat resistance performance and flame retardant performance is guaranteed, the current can reach the quality requirements must be big brand products, such as ke, Moore, focus on the study of the hot melt adhesive, provide customized hot melt adhesive application solutions, wide range of USES, can be applied to new energy, military industry, aviation, shipbuilding, electronics, automobiles, instrument, power supply, high iron, and other areas of the industry.
In bonded abrasive products, the main purpose of the sticky material is used as structure adhesive.
Although some hot melt adhesive at the time of operation will be some smell, but is completely disappeared after curing, so the hot melt adhesive is safe, can be used in electrical parts of adhesive.
Xiaogan production packaging glue direct 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.
Hot melt adhesive film 1.
Non-toxic, no smell, high transparency, no yellowing;
Industrial glue adhesive is a kind of application classification, industry used for homogeneous or heterogeneous surfaces connected together with adhesives, adhesive has the stress distribution of continuous, light weight, or seal, most of the low temperature process.
And check the usage of the dryer.
Hot melt adhesive is a kind of plasticity strong adhesive, and the adhesive can be adhesive, and a variety of substances can changes with temperature changes in the nature, after curing adhesion
, adhesive strength is big, so many industries can use this kind of adhesive.
If the adhesive is for ordinary families, the quality is not important.
If it is used in the industrial field, requires attention to quality, so how to determine the quality of the hot-melt adhesive?
Compound modification to improve some properties of the waterborne polyurethane, and other water-based resin such as epoxy resin emulsion, urea-formaldehyde resin, such as blending, made the new water-based adhesive
, its performance is improved.
Xiaogan production packaging glue direct and then cooled to stir 60 ℃, adding 0.
10 and 1 gk12, after half an hour to make sufficient emulsification stir with a third mixed monomer and ammonium persulfate solution by one-third.
In general: industrial glue has high strength, large temperature range of applicable temperature, viscosity range, low price, easy production, and other characteristics.
