Guilin industry contact pressure sensitive adhesive industry contact pressure sensitive adhesive)
, also should have appropriate toughness.
By bonding surface treatment: hot melt adhesive for bonding material surface treatment no other adhesive is so strict, but be dust on the surface of the adhesive material, oil should also do the appropriate processing, their best to make the hot melt adhesive glue.
Listed above the product performance and application of information to the long-term practical experience and gained by the certain experimental conditions, reference for users when choosing products and operations.
Four, the stand or fall of printing ink, glue move mainly related to viscosity, viscosity, the greater the transfer efficiency of the poor (
Improve process using performance excellent emulsifying equipment for heat treatment, can improve the strength and water resistance of film.
Homework time: homework quickly is an important characteristic of hot melt adhesive.
Hot melt adhesive homework time generally in 15 seconds, with modern production mode -
The widely application of the assembly line for hot melt adhesive and shorter operation time.
Adhesive coating mold nitrile - two phase
The emergence of phenolic resin/epoxy film and nylon
Epoxy and nitrile -
The use of epoxy glue, helps overcome nitrile -
Some shortcomings of the phenolic glue film, can make the single adhesive on the edge and skin with honeycomb structure adhesive.
Resistant temperature: hot melt adhesive are more sensitive to temperature.
The temperature reached a certain degree, hot melt adhesive began to soften;
Below a certain temperature, hot melt adhesive will become fragile, so choose hot melt adhesive must give full consideration to the environment temperature change.
General models: OSD main features editor stored in a cool, ventilated place, environment temperature 5 ~ 40 ℃, 6 months shelf life.
Sticky: hot melt adhesive sticky points late early viscosity and viscosity.
Only late early viscosity and viscosity is consistent, can make the hot melt adhesive and the adhesive stability.
In the process of production of hot melt adhesive, shall guarantee that the oxygen resistance, brine resistance, resistance to acid, alkali and a plastic.
Guilin industry pressure sensitive adhesive contact but with in the process of actual operation, there are many factors is not the company's control, such as: work environment, climate conditions, operations management, the moisture content of wood and tree species selection, glued material quality, pressure and time pressure conditions, sizing method, sizing and mix proportion, etc will affect the bonding effect.
In addition to acrylic, polyurethane, silicone type of UV curable Conformal Coating, epoxy and acrylic modified polyurethane UV curing the Conformal Coating.
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?
Guilin industry contact pressure sensitive adhesive used tools before drying of glue can be used warm water to clean.
Life activity of adhesive adhesive development activity includes two categories: soft woven adhesive and hard tissue adhesive.
But the basic performance can be roughly divided into two categories: the emulsion performance and mechanical properties of the pressure-sensitive adhesive.
1, can under the professional instrument for testing analyzing the composition of hot melt adhesive, so that we can get the accurate data.
UV type: the most chemical types can be UV curing methods.
Guilin industry pressure sensitive adhesive contact civil jet flying machine adopts adhesive for bonding the horizontal and vertical wing board, brush ji, tapered tail and head of radome assembly.
