Present invention also offers a kind of nylon membrane, any of the above-described welding method prepare.
Invention further provides the application in nylon membrane welds of the ethylene acrylic acid co polymer film.
The welding method of the nylon membrane of the present invention, only needs during welding to be clipped in be welded two by welding auxiliary film
Between block nylon membrane, use existing film solder equipment to weld according to existing welding procedure, be a kind of
Simply, the welding method of nylon membrane practical, efficient.
Detailed description of the invention
Embodiment inventive features will describe the most in detail with the exemplary embodiments of advantage.It should be understood that
Be that the present invention can have various changes in different embodiments, it is all without departing from the model of the present invention
Enclose, and therein being described in substantially is treated as purposes of discussion, and be not used to limit the present invention.
An embodiment of the present invention provides the welding method of a kind of nylon membrane, is placed in including by auxiliary for welding film
The joint of two nylon membranes to be welded, welds.
In the present invention, weld auxiliary film and play the effect of " welding rod ", fold up welding auxiliary film to be welded
The joint of two nylon membranes, heats this joint with welding equipment and bestows pressure, making welding auxiliary
Film fusing forms weld seam, obtains the nylon membrane of welding after cooling.
Weld auxiliary film and be preferably ethylene acrylic acid co polymer film, such as, can be 41E687 by model
The blown film of Du Pont's raw material.The thickness welding auxiliary film can weld auxiliary film between 0.1～0.35mm
Width is advisable with the joint covering two nylon membranes to be welded, is preferably between 5～20mm, concrete
Size can select according to the width of joint.
The welding equipment used is not limited by the present invention, and existing welding equipment is used equally to the present invention.
Wherein, the weldingvoltage of welding equipment is preferably 60～80V；Welding current is preferably 16～19A.Right
The time that joint carries out heating can be 10～20s；Bestow the pressure of pressure can be 0.25～
0.35MPa, such as 0.3MPa；Cool time can be 60～70s.
The welding of the nylon membrane of an embodiment of the present invention can be achieved by the steps of:
1) with Du Pont 41E687 as raw material, made by small-sized inflation film manufacturing machine and weld auxiliary film: can be according to 41E687
Raw material technology requirement, the corresponding parameter adjusting inflation film manufacturing machine, and it is auxiliary to adjust welding with equipment situation as required
The thickness of film.
2) width of auxiliary film is welded in cutting as required, auxiliary film width more than two nylon films to be welded it
Between joint width.
3) preheating heat-sealing machine, set heating voltage, add pressure between thermocurrent, heating plate, heat time heating time and
Cool time.
4) put between two pieces of nylon membranes welding auxiliary film, put into the most together the upper and lower heating plate of heat-sealing machine it
