Application Range

HP-669 inoshandiswa zvinobudirira muindasitiri yerabha seyakaviri inoshanda organic poly sulfur silane coupling agent.
HP-669 inogona kushandiswa mune vulcanized rabha system ine mafirita akadai silica, fiberglass, talc poda, mica poda uye ivhu seanosimbisa agent.Inogona kuvandudza zvimiro zvekusimbisa zvemafiller uye rubber abrasive resistance properties.
Yakakodzera kushandiswa seyakawedzera rubber-vulcanizing agent uye activator mumapolymers akadai seNR, IR, SBR, BR, NBR uye EPDM.
Mukati mekuita vulcanization, the crosslinking rate yepoly-sarufa alkyl yakafanana nedeoxidizing rate yesarufa, saka inoita kuti irambe deoxidization ye vulcanization, yobva yanatsiridza dynamic bending properties senge heat build up and cracks expansion .Iyo ina sulfur maatomu anogona kuita se activator ye vulcanization.
Mune simba uye static mamiriro, Inoshandiswa kugadzira izvi zvigadzirwa zverabha: tire, hose, rabha roll, bhandi, tambo, shangu uye michina yekuvamba zvigadzirwa.Inogona kuvandudza abrasive kuramba, kucheka kuramba uye kudzvinyirira kuramba, kuderedza hysteresis kurasikirwa uye hygroscopicity, kunatsiridza mechanical uye adhesive zvinhu, uye kuwedzera kupisa kuchembera kuita, modulus uye flex life.
Wedzera sulfur-silane coupling agent muindasitiri yerabha tire, haisi kungodzikisira njodzi yekubaya sezvo tembiricha yakakwira zvakanyanya mumugwagwa wekumhanya kana nguva refu, asi zvakare kuderedza roll kuramba kwevhiri, wobva waderedza kushandiswa kwepeturu. huwandu hwekuburitswa kwe CO2 sekuenderana nekuchengetedzwa kwezvakatipoteredza kwekuderedza kabhoni.
