EVA hot melt adhesive and its use (below)

using EVA hot melt adhesive environment and conditions Information, using EVA hot melt mucilaginous environment and conditions

Nowadays, advantages and more reserve books on the usage of EVA hot- melt glues for wireless binding. Just about all large, medium, and small- scale processing plants near your vicinity are used, and still a rising trend in the foreseeable future . This really is scheduled to the usage of such adhesives to make books. Swift, short cycle, good book appearance, saves several steps. However, scheduled for the eagerness of manufacturing companies to launch, target more activities, plus more handling, they've neglected the technological nature of the surroundings and conditions of hot burn adhesives, and for that reason there has been many problems in handling. Here are a few points by using reference:

1. Influence of temperature and humidity in production vegetation

EVA hot burn adhesive is a kind of thermoplastic adhesive. The roomopen time after painting is relying on the temperature and humidity of the room. Generally, the temperature in the room ( ie the workshop) should be retained at a continuous temperature. The very best temperature is between 15° C and 26° C. Humidity ought to be maintained. Approximately half%. However , it's understood that inside the units involving hot burn adhesives through the, it is extremely rare to make this happen requirement. Therefore, when there are numerous areas involving hot burn adhesives, there are several summertimes of excessive utilization of plastic pockets, that are difficult to eradicate and cool. In the cold weather , adhesive curing, shortening in the cooling time, stickiness or period of time readers stay, and breaking of books after sticking occurred. Consist of locations, because of the high dampness, the book following the cover is indeterminate, plus it can't be cut. These phenomena are directly related to the temp and humidity of the working plant. So ask:

( 1) Conditional units, try to install continuous temperature equipment and humidity measurement equipment in our factory building with wireless stuff binding equipment so that the conventional temp and humidity.

( 2) Some wholehearted units must also try to create conditions for scientific and standardised management and production. Inside shortage of these conditions can in the short term grasp the following principles: When ever the summer temperature is high, the use of hot burn adhesive temperature should be reduced by about 10° C, so that the glue opening and curing time can basically meet the reasonable requirements.

( 3) Literature made by wireless glue holding shall be guaranteed to have a temperature of between one particular and 45° C in the storage place or workshop where they are stored, and are forbidden to be stacked against the wall membrane, by heating( in winter), by the windows and in the open air. Avoid moisture or excessive heat to deform the paper, leading to the glue to alter, leading to irreparable destruction.

Fourth, the employment of EVA hot melt adhesive should pay attention to matters

EVA hot burn adhesive, unlike ordinary cold stuff, according to its characteristics, must grasp and pay attention to the following points in use:

1. To comprehend and keep up with the various models and techie performance( including technical parameters) of EVA hot melt adhesives. Distinct kinds of hot- burn adhesives will vary opening times and curing times. Specifically, the use period of Xiajiao and Dongjiao must be strictly differentiated. If your temperature is significantly diffent, the opening and curing time may also change.

2. When working with EVA hot melt adhesive, avoid direct heating with open fire, be sure to use spacer oil solution heating( point at which water boils to 100° C), or use sealed electric heat plate.

3. The solid AVOI hot melt adhesive must certanly be preheated using a preheating device before it is employed, and released into an operating plastic benefits of the glue glue. The loosen up time is usually about two several hours. When glue is used, no solid glue block( that is, glue that has not also been preheated) can be directly blended into the plastic housing to prevent the fluidity of the glue from being poor and also the glue from being completely dissolved on the back of the book. Book appearance quality.

4. Preheat the amount of stuff in the plastic pot to grasp properly, after the amount of excessive colloidal melt, it will eventually deteriorate aging, viscosity, affect the adhesion.

5. During the beginning time of the melt glue, all the bonding processes must be completed. In case the machine prevents in the event of a fault, the books in the book holder must be removed in time. Special attention should be paid to the reality that the book block above the rubberizing wheel should never stay.

6. When fixing the wi- fi glue- binding equipment for some time , the pre- adhesive and the running glue pan ought to be power down to avoid the aging from the gel.

7. The temp from the molten colloid should be strictly managed inside the scope useful.

8. To brush your pre- glue pans and working plastic bins regularly, keep the insides in the glue pans clean preventing impurities within the glue solution from depositing and accumulating, impacting the accuracy in the temp control, and also resulting in the failure from the thermal to cause the colloid to burn. Generally, under normal development and procedure conditions, the preheated plastic pot should be cleaned out once every 3 months, the significant plastic box( for rubber coating) should be cleaned once every half month. Clean up the plastic pot to set a system to facilitate implementation.
