Possible reason |
Solutions |
|
All glue membrane move towards instep. (sole separating from glue)
|
1. Ruber sole not full roughing.
2. Sole not treating or using wrong primer.
3. Primer not stoving or stoving temperature of primer too low.
4. In the middle of glue, hardener is not enough.
|
1. Ruber sole roughing as far as possible until smooth surface disappearing.
2. Exactly distinguish sole material type, using proper primer.
3. Treatment agents stoving as far as possible and raising stoving temperature.
4. In the middle of glue RF hardener is enough.
5. After treating EVA sole, it would be best that you irradiate EVA sole with ultraviolet
ray. |

All glue membrane move towards sole. (instep separating from glue)
|
1. Cowhide, PU covering leather roughing not enough.
2. Fur roughing not uniformly.
3. Leather not treating or using wrong primer.
4. Primer not stoving |
1. To cowhide, PU covering leather roughing deeply. It would be best that everywhere
have white hair.
2. Fur roughing uniformly.
3. Leather cover using proper treatment agents.
4. Treatment agents stoving as far as possible and raising stoving temperature.
5. After leather cover drying, it would be best that you treat leather cover. |
|
Sole and instep having glue, but not bonding or bonding bad. |
1. Pressuring not arriving location. 2. Pressuring not timely.
3. Unevenness. |
1. Try one's best to pressure location, particularly shoe around pressured with
hammer or wheel rolling.
2. Gluing a time again.
3. Oven which is close to pressure machine move one half distance toward pressure
machine. |
|
Sole and instep having glue but viscose long or bonding bad. |
1. Hardener is not enough.
2. Not dry enough in glue meimbrane. 3. The temperature of oven is too high. |
1. Increase amount of hardener.
2. Increase the temperature of oven or decelerating assembly line.
3. Adjust temperature of oven to 60℃ - 65℃. |
|
Some bonding well, some desquamate from glue. |
1. Roughing not uniformly.
2. Pressuring not uniformly.
3. Gluing not uniformly. |
1. Roughing uniformly as far as possible.
2. Do one's best to pressure everywhere.
3. Gluing uniformly as fas as possible. |
|
Shoe-head or heel getting up silk or leaping. |
1. Glue resisting to wiredrawing not enough.
2. Shoes coming from oven cold time not enough. |
1. Changing resistance wiredrawing.
2. Increasing the distance between oven and pressure machine. |
