Row vulcanization；
(2) curing temperature is adjusted to 180~200 DEG C, and controls plate temperature to be 110~120 DEG C, be allowed to constant；
(3) mould is placed on closure flat board and be preheated within the scope of defined curing temperature ± 1 DEG C, and at such a temperature
Keep 20~30min；
(4) when vulcanizer works, sulfide stress is provided by pump, pressure is adjusted to 25MPa by pressure-regulating valve；
(5) compound blank is quickly put into preheated mould, immediately matched moulds, is placed in flat board center, up and down each layer vulcanizing mold
Type is aligned with the after-applied pressure in same orientation, flat board is increased, when pressure gauge indicates to arrive 15MPa, appropriate release exhaust 3~4
It is secondary, then pressure is reached 25MPa, start to calculate cure time, reaching scheduled time pressure release immediately in vulcanization opens mould, takes out examination
Sample；
(6) sample shear after vulcanizing is removed photoresist side, and performance test is carried out after placing 10~13h at room temperature.
Further, elastomeric compound is examined：Test is sampled to the elastomeric compound after mixing, method and test value are according to as follows
Procedure and numerical value are carried out, and choose the qualified elastomeric compound of whole test values：
