Okutegeeza:

Guanidine accelerator is the largest basic accelerator.It is a medium speed accelerator for natural rubber and synthetic rubber.When using guanidine accelerator alone, the vulcanization starts late, the operation safety is great, the storage stability of the mixed rubber is good, but the vulcanization speed is slow (it is 1 times slower than sulfonamide accelerator).Guanidine Accelerator vulcanizate ye mpisa esinga obunene ey’obugumu obw’ekika ekya waggulu, ekivaamu obukaluba obw’amaanyi, okunyigirizibwa okw’okusika okw’amaanyi.[1]

However, due to the existence of a large number of polysulfide bonds and more cyclic compounds in the vulcanizates, the vulcanizates have poor heat resistance, cracking and compression deformation.In addition, this kind of accelerator has discoloration and pollution, not suitable for white products.Because vulcanization speed is slow, heat resisting ageing is poor, so guanidine kind stimulant is not used alone commonly, and the 2nd stimulant that serves as thiazole kind, second sulfonamide kind.When used together, the activation effect is particularly strong, used in the production of rubber board, sole, bicycle tyre, industrial products, thick products and hard rubber products, the glue material with guanidine as the second promoter is suitable for all vulcanization methods.However, when used as a first accelerator, it is so late Mu vulcanization nti okutwalira awamu tekisaanira mpewo eyokya vulcanization.
