Awhe Taupānga

E whakamahia angitu ana te HP-669 i roto i te umanga rapa hei kaihoko hononga polywhara silane waro mahi rua.
Ka taea te whakamahi i te HP-669 i roto i te pūnaha rapa whakamomona me ngā whakakī pēnei i te silica, te muka karāhe, te paura talc, te paura mika me te uku hei kaihoko whakapakari. Ka taea e ia te whakapai ake i ngā āhuatanga whakapakari o ngā whakakī me ngā āhuatanga ātete rapa ki te karawarawa.
He pai hei whakamahi hei tāpiri rapa—hei kaiwhakapūkara me hei whakahohe i roto i ngā pūmua pērā i te NR, IR, SBR, BR, NBR me te EPDM.
I roto i te tukanga whakamomona, he rite tonu te tere honohono o te poly-sulfur alkyl ki te tere tango-haukini o te whanariki, nō reira ka mahi hei ātete i te tango-haukini o te whakamomona, kātahi ka whakapai ake i ngā āhuatanga piko hihiri pēnei i te hanga wera me te whakawhānui o ngā kapiti. Ka taea e ngā ngota whanariki e whā te mahi hei whakahohe mō te whakamomona.
I roto i ngā āhuatanga hihiri me ngā āhuatanga pūmau, ka whakamahia hei whakaputa i ēnei hua rapa: potae, ngongo, roera rapa, whitiki, taura, hu me ngā hua whakatū mīhini. Ka taea e ia te whakapai ake i te ātete ki te haehae, te ātete tapahi me te ātete pēhanga, te whakaiti i te ngaronga hysteresis me te hygroscopicity, te whakapai ake i ngā āhuatanga mīhini me te piri, me te whakanui ake i te mahi koroheketanga wera, te modulus me te roa o te ora piko.
Mā te tāpiri i te ākena hononga whanariki-silane ki te umanga potae rapa, ehara i te mea ka whakaiti noa i te tūponotanga o te poka i te pāmahana teitei rawa i runga i te rori tere, i te wā roa rānei, engari ka whakaitihia hoki te ātete hurihuri o te potae, ka whakaitihia te whakapaunga penehīni, ka whakaitihia te nui o ngā tukunga CO2 kia pai ai te tiaki taiao mā te whakaiti i te waro.
