Ekintu kino kya 'accelerator' ku CR ez'enjawulo, chlorosulfonated polyethylene rubber, CHR, polyacrylate rubber. Esaanira okufuuka vulcanization eya vulcanized okuyita mu metallic oxide. Ekintu kino kisobola okulongoosa situleesi y’okusika n’okukendeeza ku kukyukakyuka wansi w’okunyigirizibwa, naddala nga kisaanira 54-1(w) ne GN CR ne cable eya bulijjo, kyangu okusaasaana era tekikyuse langi.

Mu nkola ya ETU promoter for neoprene, oluvannyuma lw’okugattako TT, obudde bwa coking bwali buwanvuye, density ya crosslinking yakendeezebwa, amazzi galongoosebwa, era eby’obutonde n’ebyuma byakyusibwa bwe biti:

1.Okukyukakyuka kw’okunyigirizibwa okw’olubeerera kweyongera.

2.Obuzito bwakendeera, amaanyi gaakyusa kitono, okuwanvuwa kweyongera.

3.Eky’obugagga eky’okukaddiwa kyeyongera, okuwanvuwa kukendeera nnyo era obukaluba bweyongera mu ngeri ey’olwatu.

4.Oluvannyuma lw’okukyusa ETU ne HVA-2, crosslinking density ne vulcanization rate y’ekyesiiga yakendeera, omulimu gw’okukaddiwa gwalongoosebwa, era okunyigirizibwa okw’olubeerera okukyukakyuka kwakendeera, nga kino kyali nga kitundu kya ETU adhesive.

5.Mu nkola ya HVA-2, amazzi agaasooka gaali wansi okusinga aga ETU. DM ne TT zaali zisobola okukozesebwa okulongoosa okwokya kwa coke n’amazzi.TT yali esinga DM (amazzi), naye eky’obugagga eky’okukaddiwa ekya DM kyali kisinga TT.

6.When DM was used as the promoter of hva-2, the crosslinking density decreased, the permanent compression deformation was slightly lower than that of hva-2 alone, and the elongation and tear were improved.After the addition of TT, the elongation rate was significantly reduced, mainly because TT did not participate in the crosslinking at the initial stage and improved the scorchability, but at the later vulcanization stage, TT participated in the crosslinking and increased the Crosslinking density, kale omulimu gw’okukaddiwa ogwa TT gwali mubi okusinga DM.ne bwe guba, HVA-2 +TT erina omulimu omulungi ogw’okukaddiwa n’okunyigirizibwa okw’olubeerera okusinga ETU yokka.
