A, the vulcanization process
Conveyor belt on the plate vulcanizing machine with constant section sulfide (single or double). Sulfide check well before of semi-finished products specifications, with the corresponding thickness of the pad iron and iron, with embryo into a flat space in accordance with the provisions after stretching, using low pressure plate jacking, then switch to high pressure tight, and vulcanization process specified in the standard terms and conditions.
Second, take embryo sulfide spin rules
(a) polyester/cotton canvas conveyor belt
4 layer and 4 layer under stretch 3-4%
Above 5 layer and five layer stretch 3.5-4.5%
Rubber polyester-cotton canvas conveyor belt stretching amount reduced 0.5%.
Decorative pattern conveyor belt spin:
The fishbone pattern conveyor belt stretched three or four patterns
Cylindrical pattern (dip) 1-1.25 a pattern conveyor belt stretching.
(2), EP conveyor belt, nylon: 0.5-1%
A, finished tape sizing rules
(a) terylene belt 2-3%
Nylon conveyor belt is 4.5-5%
EP conveyor belt 2-3%
(2) the sizing stretching method: after finished tape out of the pot, pot sulfide end of a long, should immediately with pull out machine will tape straight, and then to start the cold stretch plywood according to the regulation of cold quantity for sizing the reach, and to start the fan cooling, the interval shall not be more than 1 minute. Falling pot closed 5 minutes before the fan, cold and plywood.
(3) the two tape adapter or the first pot, and finally a pot and traction with joint tc conveyor belt and EP conveyor belt cold stretching amount can reduce to 1-2%, nylon conveyor belt cold quantity can reduce to 2-3%.
Second, vulcanizing compression ratio
Polyester/cotton canvas conveyor belt: 8-18% (including cold resistant, heat resistant, acid and alkali resistant, oil)
Nylon, EP conveyor belt: 8-15%
Note: should press with embryo actual equipped with shim thickness calculation.
