Nanning henkel how hot melt adhesive
nanning henkel hot melt glue flavour is sensory perception, the equivalent of sensors, refers to the molecule in the senses (
After the surface produce the quantity change (
Physical quantities can be electric, magnetic, optical, length or volume, ion flow, molecular flow, etc. )
Through to the CPU (the signals produced by,
Packing books in (3) found plastic brush with agglomerate, gel, should immediately remove it with boiled water,
Acrylic pressure sensitive adhesive general is given priority to with solution type, there are few is water-based pressure-sensitive adhesive, hot melt pressure sensitive adhesive main composition of acrylic can serve as a soft monomer and hard monomer, functional monomer composition of the three.
Hot melt collagen material resin by subject, viscous tree, thinner, or with the softening agent of oil, add ingredients, such as inherent smell smell of hot melt adhesive is an important raw material sources, such as most of the EVA is a little hint of acetic acid taste, and synthetic rubber also has its own smell, just different shades, viscosity resin in the resin viscosity resin has the smell of turpentine, and C9C5 resin have their different tastes, even the whole hydrogenation resin, also has its own smell, it's just our sense of smell may be aware not to come out and many other raw materials also smell, tints, only the intensity difference.
Appearance white granular pale yellow flakes nanning henkel hot melt adhesive how late only early viscosity and viscosity, hot melt adhesive and the adhesive material can remain stable.
Too much instead of molten refers to its low melting temperature of the glue, liquidity is good but lower bond strength.
Melting point (
84, 65 -
78 nanning henkel how about hot melt glue smell is one of the types of people in foreign material object feeling, different people have different feeling to the same kind of material, is used to eating by people, work experience, education degree, personal preferences, the influence of such factors as the smell of a like another person may hate the smell of a people hate others can like it very much, really for all tastes.
Tackifier viscosifier is the main assistant EVA hot melt adhesive.
The viscosity of 2500 -
3500, 5500 -
6500 nanning henkel: how about hot melt glue shape to the points can be divided into hot melt colloidal particles, hot melt adhesive stick, hot melt adhesive, hot melt glue, hot melt glue powder, etc.
Sticky: hot melt adhesive sticky points late early viscosity and viscosity.
Viscosity regulator viscosity regulator is also the main auxiliary hot melt adhesive.
Hardness is 78 -
82, 65 -
44, hot melt adhesive, observe whether there is a powdery material after melting, if there are captions powdery material packing, adhesive performance is poor.
If only * with basic resin melt at certain temperatures have cohesive force, when the temperature drops, it will be difficult to wetting and penetration on paper, lose binding ability, cannot reach bonding effect;
Adding tackifier can improve the liquidity of colloid and wettability of glued objects, improve the bonding performance, to achieve the required bond strength.
