Qinghai qinghai henkel sealing glue equipment of the German henkel sealing glue equipment main equipment and instrument, but most of the existing reactive flame retardants are unable to greatly improve the flame retardancy of pressure sensitive adhesive, also need to be appropriate to add some additive flame retardant, two or more than two kinds of flame retardant association effect, can maintain the pressure sensitive adhesive pressure sensitive resistance and flame retardant balance at the same time, improve the flame retardancy.
Physical and chemical bonding effect, the overall strength of adhesion
after carton, carton is not easy to deformation and cracking.
In addition, hot melt adhesive coating system can be to press the rubber coated in different shape of key parts, such as: cartons cover fold.
Most of one-component polyurethane coating in the application need to be careful, strict control of coating and curing environment.
Second, poor adhesive with good low temperature resistance, cold climate in the north, does easy to glue;
Hot melt adhesive, good low temperature resistance, resistant to -
40 ℃ low temperature.
And the storage life of hot-melt adhesive for 2 years, store covers an area of small, no special storage requirements;
And tape storage is valid only for half a year, also requires a certain storage conditions, otherwise easy to spoil.
And the successful application of adhesive can promote advanced heat resistant, high strength composite materials, such as carbon fiber, boron fiber could be used in the aviation industry, the aircraft structure was further improved.
In addition, hot melt adhesive also provides a good anti-theft function, due to the adhesive penetration into the corrugated any attempt to open the carton will tear fiber.
Tape available knife cut, in imperceptible in take contents and sealing again.
Qinghai henkel sealing glue equipment but high dosage of emulsifier and will reduce the resistance to water of pressure sensitive adhesive and sizing the bubble too much, influence the construction performance.
Since it is a kind of colloid structure, so lots of pores and large specific surface area.
Appearance: qinghai henkel note editor polyurethane sealing glue equipment type: have good wet resistance, chemical resistance, excellent electric properties.
Epoxy resin epoxy resin with low shrinkage rate, resistance to mildew, properties, such as stable point.
Goods packaging in transmission nowadays, businesses at the same time, through the packaging pattern design can also communicate product and company image.
Therefore, appearance factors hindering the research on the role as little as possible.
Packing tape often block image, interference information transfer;
And hot melt adhesive bonding between folding wing, can provide larger display space.
In addition, emulsifier dosage has a great influence on the stability of the emulsion, in early when the dosage of emulsifier emulsion polymerization stability is poor, prone to demulsification phenomenon, with the increase of emulsifying use, gradually tends to a stable emulsion.
In the 21st century, the development direction of industrial glue is embodied in the following nine aspects.
Qinghai henkel sealing glue device 1, when cleaning pur polyurethane hot-melt adhesive machine, you must first make the hot melt adhesive plate away from the pur hot melt glue barrel and pur polyurethane hot melt adhesive glue barrel with pur hot-melt adhesive machine, after the hot dish out should be in keeping the lift cylinder under the condition of internal pressure, cut off all the power.
Three, printing ink, glue viscosity change brings to the purchasing question modification: four, automotive electronic melting point: 105 -
115 ℃ : melt index: 18
Size: 80 -
120 mesh food with silica gel is made from silicate polycondensation of inorganic polymer gel material, ingredient is SiO2 · nH2O, its content is over 98%, avirulent insipidity, stable chemical performance, under the normal except hydrofluoric acid and caustic, not any response from the acid and alkali salt.
