Ngā tono mō te polypropylene
E mōhiotia ana te PP mō tōna kaha, tōna ngāwari, me tōna ātete ki ngā matū. He maha ngā wā ka whakamahia te PP i roto i te hanga takai kai, ipu rokiroki, wāhanga motuka pēnei i ngā parepare, me ngā kiriata kirihou uku mō ngā pākahiko.
3. PVC (Polyvinyl Chloride)
Ngā momo PVC
– PVC mārō
– PVC ngāwari
Ngā Taupānga PVC Pakari
E whakamahia ana te PVC pakari i roto i te hanga paipa, anga matapihi, me ngā kōtaha whare. Nā tōna kaha me tōna ātete ki te ahi, he mea pai rawa atu tēnei mō te hanga whare.
Ngā tono PVC ngāwari
E whakamahia ana te PVC ngāwari i roto i ngā taura hiko, ngā uhi papa, me ngā whakapaipai whare. Nā tōna ngāwari me tōna ngāwari ki te whakakorikori, he tino whai hua ki ngā momo mahi maha.
4. Porotireini (PS)
Ngā tono mō te polystyrene
Ka kitea te polystyrene i roto i te pahuka (pērā i te Styrofoam) me ngā kirihou mārō. Ko ngā whakamahinga noa ko ngā ipu kai tere, te whakamahana wera, me ngā takai tiaki. Ko ōna painga ko te iti o te utu me te ngāwari o te hanga.
5. Polyethylene Terephthalate (PET, PETE rānei)
Ngā tono PET
He whānuitia te whakamahinga o te PET i roto i ngā pounamu inu me ngā takai kai. Nā tōna māramatanga whatu, tōna kaha, me tōna pumau matū, he mea pai tēnei mō ngā tono e hiahiatia ana te māramatanga me te ārai i ngā hau me te makuku.
6. Acrylonitrile Butadiene Styrene (ABS)
Taupānga ABS
He maha ngā wā ka whakamahia te ABS mō ngā hua hikohiko kaihoko pērā i ngā pouaka rorohiko, ngā taputapu whare, me ngā wāhanga motuka. Nā tōna ātete ki te pānga me tōna ngāwari ki te pokepokea ai, he mea rongonui ai i roto i ngā momo ahumahi.
7. Nairona (Polyamide)
Ngā Taupānga Nairona
E whakamahia ana te nairona i roto i ngā kakahu hei hanga papanga, tae atu ki ngā wāhanga mīhini pērā i ngā taputapu me ngā peera. Nā tōna kaha miihini me tōna ātete ki te kakahu, he mea rongonui i roto i ngā mahi hangarau.
8. Polycarbonate (PC)
Ngā tono Polycarbonate
E mōhiotia ana te PC mō tōna ātete pai ki ngā pānga me te mārama o te tirohanga. E whakamahia ana i roto i te hanga karāhe haumaru, ngā karāhe tirohanga, me ngā taputapu hauora. Nā ēnei āhuatanga anō hoki i whakamahia pinepine ai i roto i ngā tono hanganga kaha-teitei.
9. Polyurethane (PU)
Ngā tono Polyurethane
He maha ngā momo whakamahinga o te PU, tae atu ki te pahuka ngāwari me te pahuka pakari. Kei roto i ōna whakamahinga ngā moenga, ngā urunga, me te whakamahana wera. Nā tōna kaha ki te hanga ki ngā momo pakeke me te ngāwari, he tino whai hua te PU i roto i ngā momo mahi ahumahi.
10. Polytetrafluoroethylene (PTFE)
Ngā tono PTFE
E mōhiotia whānuitia ana te PTFE e te ingoa waitohu Teflon, ā, e whakamahia ana i roto i ngā mahi e hiahia ana ki te ātete matū me te pāmahana teitei, pērā i ngā gaskets, ngā hiri, me te whakamahana hiko. Nā ōna āhuatanga kore-piri, he mea pai hoki mō ngā taputapu tunu kai pērā i ngā kohua me ngā paraharaha.
Whakamutunga
He āhuatanga ahurei tō ia momo kirihou, ā, he mea tino pai mō ngā tono motuhake. Mai i te ngāwari o te LDPE ki te kaha ā-pūkaha o te nairona, mai i te mārama o te PET ki te ātete matū o te PTFE—he mea nui te mahi a ngā kirihou ki te whakatairanga i te ahumahi hou. Mā te mārama ki ngā momo kirihou me ā rātou tono noa ka taea e ngā ahumahi te whiriwhiri i te rauemi tika hei whakatutuki i ā rātou hiahia. Ehara i te mea ka whakapai ake i te pai me te kounga o te whakaputanga anake, engari ka tautoko hoki i te auahatanga me te pumau. Nō reira, he mea nui te mōhio ki ngā momo kirihou me ā rātou tono mō ngā tohunga ahumahi katoa.
