I-DPG kwi-Rubber Compounding
I-Diphenylguanidine yenye yezona zikhawulezisi zerabha zindala nezisetyenziswa kakhulu. Xa isetyenziswa kunye nezikhawulezisi ze-thiazole okanye i-sulfenamide eziphambili, i-DPG ivuselela inkqubo yonyango, iphucula ukusebenza kakuhle kwe-crosslink, kwaye yandisa ukhuseleko lokutsha kwiqondo lobushushu eliphezulu lokucubungula. Ikwasebenza njengesicoci se-asidi, inceda ukuzinzisa iikhompawundi eziqulethe i-carbon black okanye i-silica fillers ezine-acid surface chemistry. I-DPG ibaluleke kakhulu kwiikhompawundi zamatayara ezizaliswe yi-silica, apho idlala indima ephindwe kabini njenge-accelerator kunye ne-silanol neutralizer.
Inqaku loLawulo kunye noNikezelo
I-DPG ikhupha i-aniline ngexesha lokuxuba, into ejongwa ngumsebenzi. I-Terracore inika i-DPG kwiingxowa zephepha ezingama-25 kg okanye kwiingxowa zomgubo. Ifomu exutyiweyo iyafumaneka ukunciphisa ukuvezwa kothuli ngexesha lokuphathwa. I-COA epheleleyo kunye ne-SDS kunye neemfuno zococeko lomsebenzi ziyabonelelwa.
