Nanchang how much how much adhesive
nanchang authorized adhesive analysis of each peak, discuss its composition [
Characteristics of the construction is convenient, the equipment cover an area of an area small, save manpower, and can be sprayed, roller coating, coating, dots, lines, and so on.
Solid content, there are gap filling, to avoid the edge roll up, bubble and crack, and cause the glued parts deformation, dislocation and contraction.
Because there was no solvent, lumber moisture content is not change, no fire and poisoning.
2, can also be observed in appearance, if the hot melt adhesive glue type, do manual work is coarser, then the quality.
Adhesive, coating and adhesive between several seconds, however, saw the head and trimming can be finished in 24 seconds, do not need drying time, can be used for continuous, wood adhesive production line automation, improve the production efficiency, save the cost factory.
Object of adhesive, bonding and sealing, wide application range, paper, plastic, metal, ceramic and so on all have better stick relay;
1, can under the professional instrument for testing analyzing the composition of hot melt adhesive, so that we can get the accurate data.
Widely used for bonding a variety of materials.
Nanchang authorized adhesive how much 5, used the occasion of pur polyurethane hot melt adhesive machine should guarantee the rapid flow of air.
After a sticky refers to cementing, respectively by a certain external force have been destroyed by the continuous shear under the action of time.
Can be several times of adhesive, coating on the wood hot melt adhesive, do not meet the requirements for cooling solidification, can be reheated for secondary bonding.
Nanchang authorized adhesive (how much money
Ammonium persulfate 0.
Poly (vinyl alcohol) 1.
Take a small amount of lotion to pass 3 g methanol precipitation, filtration vacuum drying after washing, take a small amount of measure its infrared spectrum.
Because the viscosity test medium pressure sensitive adhesive is cohesive failure (
Will leave a residue glue)
, so the viscous mainly reflects the cohesion strength of rubber.
Textile nanchang authorized adhesive added how much is 6, pur hot melt glue, should check whether pur hot melt glue barrel distortion, deformation serious pur polyurethane hot melt adhesive glue barrel used should be abandoned, avoid damage to pur hot melt adhesive machine pressure plate.
Product has good initial adhesion, stick relay is strong, fast drying speed, adhesive film good toughness and resistance to acid and alkali, antifreeze, flame retardant, non-toxic tasteless, does not affect human body health, safe environmental protection considerations note package and store PET aluminum plating film adhesive editing machine good adaptability, high peel strength, at the beginning of stick with a viscous fluid supply technical indicators brush or roller coating glue can be used in the process of should be tightly cover at any time, to prevent liquid cement crust, do not entry, can not let the child contact pressure sensitive adhesive and pressure-sensitive adhesive products have ten many explanations, the meaning of the definition of common has the following statement: 3.
Hot melt adhesive are textiles, especially using much more of a kind of adhesive, garment processing is widely used for non-woven fabrics, carpet seams, cloth lining, zippers, etc. Of the adhesive.
Applied to the hot melt adhesive on the textile industry should have good bonding strength, excellent flexibility, resistance to water to wash/dry cleaning.
In addition, because of the fabric in the process of shape, mostly through steam treatment, therefore, requires adhesive has the characteristics of high temperature steam its softening point requirements higher than 115 ℃, the third must have the appropriate degree of crystallinity, in order to improve the thermal stability of the adhesive.
With polyamide as the substrate, for example, the minimum content of 45% (
The mass fraction)
For softness excellent fabrics, insist on hot melt adhesive has lower viscosity.
Sodium dodecyl sulfate)

The above results show that acrylic acid involved in the reaction.
1 no smell odour level 4 standard:;
2 smells perceptible, but can not accept;
3 the smell of hate, can not accept, very nasty smell, can't accept it.
How much nanchang authorized adhesive when pur hot melt adhesive machine use pur glue barrel and melt pressure plate exposure to fast circulation air, due to rapid cooling, will affect the pur flow of hot melt adhesive, hot melt adhesive machine and waste of energy.
