Me pēhea te whakapai ake i ngā āhuatanga ā-pūkaha o te kirihou kua whakakīia#Te kirikiri kirihou#Te extruder kirihou#Te whakakōkī i te pelleti Elastomer

Tērā pea ka puta he panoni pai ki ngā āhuatanga ā-pūkaha o te kapia matrix mā te tāpiri i ngā whakakī, engari tērā pea ka pā kino anō hoki. Ko ngā āhuatanga ā-pūkaha o ngā kirihou kua whakakīia ko te modulus elastic, te kaha kume, te roa i te wā whati, te kaha pānga, te kaha piko, me ētahi atu.

Tuhinga Motuhake

I te nuinga o te wā, he iti te modulus elastic o te kapia. Ahakoa te polyester me te polyamide he nui ake te modulus elastic, he 2.5% ki te 10% noa iho o te modulus elastic o te konganuku. He maha ngā wā ka nui ake te modulus elastic o ngā whakakī i te modulus elastic o te polymers, nō reira, mā te tāpiri o ngā whakakī ka whakanui ake i te rerekētanga pīngore o ngā kirihou kua whakakīia.

I te nuinga o te wā, ka iti ake te whakanui ake o te kaha o te pūnaha whakakī mā te whakamahi i ngā whakakī matūriki nunui. Heoi, ina he nui ngā āhuatanga poutū me ngā āhuatanga whakapae o ngā matūriki whakakī, pērā i ngā whakakī papatahi me ngā whakakī muka, ka tino piki ake te kaha o te pūnaha whakakī.

Te kaha o te wera

I roto i ngā kirihou kua whakakīia, ko te whakakī he wāhanga marara kua wehea hei wāhanga tonu i hangaia mai i te kapia matrix. Me iti ake te horahanga o te kapia matrix i te wāhanga kaha i tērā o te rauemi i hangaia mai i te kapia parakore. I raro i te mahi a te kaha o waho, ka ngāwari te tango i te kapia matrix mai i te mata o ngā matūriki whakakī. Ka kumea wehea, kia iti ake te kaha kume o te kirihou kua whakakīia i tērā o te pūnaha kapia parakore.

I raro i te mahi a te ahotea kume, ka kumea te matihiko mai i te mata o ngā matūriki whakakī, ka hangaia he kōhao ririki. He rerekē te taupū whakaata o te hau i roto i ngā kōhao mai i te rauemi e karapoti ana, ā, ka puta te tae o te rauemi he mā ake i te rauemi taketake, koinei te āhuatanga o te mā i te ahotea. Ko te nui ake o te rahi o te matūriki whakakī, ko te iti ake o te tūponotanga ka huri ngā matūriki me te kapia matihiko, ā, ka kitea nuitia te āhuatanga mā i te ahotea.

Heoi, kāore i te iti ake te kaha kume o ngā pūnaha whakakī katoa i te kapia matrix. Mā te whakakī tino pai kua tukatukahia ki te mata ka whakanui ake i te horahanga whakapā i waenga i te whakakī me te kapia, ā, ka whakapai ake i te piri i waenga i te whakakī me te kapia matrix. I raro i te mahi a te ahotea kume, ka taea e te whakakī te neke me te whakapēhanga o ngā matūriki me te kapia matrix, ka whakanui ake i te whakawhiti-wāhanga whai hua hei tu atu i ngā kawenga o waho, ā, ka whakapai ake i te kaha kume o te pūnaha whakakī, he teitei ake i te kaha kume o te matrix. He ngoikore te piri i waenga i te polyethylene me ngā whakakī, engari ina totorohia te matrix, ka taea te whakatakoto ki te taha o ngā matūriki whakakī, nō reira ka taea e te nuinga o ngā whakakī te whakanui ake i te kaha kume o te polyethylene. Hei tāpiri, ka taea hoki e ngā whakakī papatahi mata teitei, ngā whakakī muka rānei te whakapai ake i te kaha kume o te pūnaha kua whakakīia.

Elongation i te waahi

Nā te mea he pakari te nuinga o ngā whakakī, inā koa ko ngā whakakī kohuke kore-ora, ā, e kore e rerekē te āhua i raro i te mahi a ngā kaha o waho, kua heke te roa o te whakakī i te wā e whati ana ngā kirihou kua whakakīia. Heoi, i kitea i roto i te whakamātautau ina iti iho i te 5% te horopeta o te whakakī, ā, he iti te rahi o te matūriki o te whakakī, he nui ake te roa o te whakakī i te wā e whati ana te kirihou kua whakakīia i te roa o te kapia matrix tonu. Tērā pea nā te iti o te kukū. Nā te mea ka taea e ngā matūriki angiangi o te whakakī te neke tahi me te matrix. He rite tonu te nui o te whakakī, ko te iti o te rahi o te matūriki o te whakakī, ko te teitei ake o te roa o te wā e whati ana.

Ko te kaha haere

Ka heke te kaha piko o ngā kirihou kua whakakīia i te pikinga ake o te ihirangi whakakī. Ka taea e ngā whakakī pereti, ngā whakakī rānei kua whakarerekētia e ngā kaihoko hononga te whakapai ake i te kaha piko o ngā kirihou kua whakakīia.

Ka pā te rerekētanga tuturu ki te pumau o ngā āhua o ngā hua kirihou. Mā te noho mai o ngā whakakī ka whakaitihia te rerekētanga tuturu o te kirihou kua whakakīia.

Te kaha o te kaha

He tohu nui te kaha o te pānga o te taputapu kirihouI roto i te anga whakakī, ka ngāwari ngā matūriki whakakī ki te kukū o te ahotea. I taua wā anō, kāore te whakakī pakari e huri i te āhua ina ahotea, arā, kāore e taea te whakamutu i ngā kapiti, te whakaputa rānei i ngā kapiti hiriwa hei mimiti i te kaha pānga. Nō reira, ka piki ake te pakarukaru o te kirihou kua whakakīia, ā, ka heke te ātete pānga. He mea nui anō hoki tēnei. He mea nui te whakarerekētanga whakakī ki te whiwhi i ngā painga maha, me te whakaiti i ngā āhuatanga o te rauemi.

I te nuinga o te wā, ina nui te rahinga whakakī, ka pā ki te haere tonu o te matihiko, ā, ka hangaia he maha ngā pūwāhi kukū ahotea, ka whakaiti i te mahi pānga o te kirihou kua whakakīia; he teitei te kaha here i waenga i te whakakī me te matihiko, ka taea te whakapai ake i te kaha pānga; nā te mea ka taea e te whakakī muka te tohatoha i te ahotea pānga ki runga i te wāhi nui ake e poutū ana ki te ahotea pānga, nō reira ka taea te whakapai ake i te kaha pānga o ngā kirihou kua whakapakarihia ki te muka; mā te tāpiri i te rapa, te elastomer thermoplastic rānei ki te kirihou hei whakanui ake i te pakari o te kirihou mā te whakaranu ka taea te whakapai ake i te ātete pānga. Ko te ariā whakapakari matūriki pakari i whakawhanakehia i ngā tau tata nei e whakapono ana ko te whakamahinga o ngā matūriki kore-elastomeric ka taea te whakapai ake i te kaha pānga o te rauemi me te kore e whakaiti i te modulus elastic o te rauemi.

Te kaha haehae me te kaha pēhanga

Ko te kaha o te haehae e pā ana ki ngā kiriata me ngā rau. Ka whakatauhia e te whānui o ngā kapiti. Me rongoa te mata o ngā whakakī hei whakapai ake i te mahi piri i waenga i ngā whakakī me ngā polymer.

Ka taea hoki e te maimoatanga mata o ngā whakakī te āwhina i te whakapai ake i te kaha pēhi o te rauemi. Mā te whakakī ki ngā whakakī ngāwari pērā i te paura rakau ka heke te kaha pēhi o te rauemi. I roto i ngā kirihou wera, mā te tāpiri i ngā whakakī he iti te ōwehenga āhua ka taea te whakanui ake i te kaha pēhi.
