Awhe Tono

He pai te whakamahi a HP-669 i roto i te umanga rapa hei maataki honohono poly sulfur silane rua.
Ka taea te whakamahi HP-669 i roto i te punaha rapa puia me nga whakakii penei i te silica, fiberglass, talc paura, mica paura me te uku hei kaihoko whakakaha.Ka taea e ia te whakapai ake i nga ahuatanga whakakaha o nga whakakii me nga taonga aukati abrasive.
He mea pai ki te whakamahi hei taapiri rapa—maamaa whakapuru me te kaiwhakaoho i roto i nga polymers penei i te NR, IR, SBR, BR, NBR me EPDM.
I roto i te tukanga o te vulcanization, ko te reiti crosslinking o te poly-sulfur alkyl he rite tonu ki te deoxidizing rate o te whanariki, na reira ka mahi ki te aukati i te deoxidization o te vulcanization, katahi ka whakapai ake i nga ahuatanga whakapiko hihiri penei i te wera me te kapiti roha .Ko te wha whanariki. Ka taea e nga ngota te mahi hei kaiwhakaoho mo te whakangao.
I roto i nga ahuatanga hihiri me te pateko, Ka whakamahia mo te whakaputa i enei hua rapa: potae, ngongo, roera roera, whitiki, taura, hu me nga hua hanga miihini.Ka taea e ia te whakapai ake i te aukati abrasive, te tapahi aukati me te aukati pehanga, te whakaheke i te mate hysteresis me te hygroscopicity, te whakapai ake i nga taonga miihini me te whakapiri, me te whakanui ake i nga mahi tawhito waiariki, modulus me te oranga ngawari.
Taapirihia he kaihoko hononga whanariki-silane i roto i te umanga potae rapa, ehara i te mea ka whakaiti noa i te tupono o te werohanga na te mea he nui rawa te wera o te rere i runga i te huarahi tere, he roa ranei te waa, engari ka whakaitihia ano te aukati o te roera, katahi ka whakaitihia te kai o te penehini, te nui o te tukunga o te CO2 hei whakarite i te whakamarumaru taiao mo te whakaheke waro.
