PVC: He kapia tūturu
Ko te PVC te whakarāpopototanga mō te polyvinyl chloride. He pūmua i hangaia mā te whakakotahitanga o te monomer vinyl chloride (VCM) me ngā mea whakaoho pērā i ngā peroxides me ngā matū azo, i raro rānei i te mahi a te mārama me te wera, e ai ki te tikanga o te whakakotahitanga o ngā rauropi kore utu. Ko te homopolymer vinyl chloride me te copolymer vinyl chloride e kiia ana ko te kapia vinyl chloride.
He tino ātete te PVC parakore ki te wera, ki te pumau, me te kukū; Engari i muri i te tāpiri i te tauira e rite ana, ka rerekē te mahi a te PVC. I roto i te whakamahinga o ngā kiriata huri tae, he maha ngā tae rerekē o te PVC, he maha ngā tae katoa, ā, he iti ngā utu. Ko ōna ngoikoretanga ko te ngāwari o te memeha, te tihore, te pakaru, me ētahi atu.
PFT: ātete ki te kakahu, ātete ki te pāmahana teitei, me te pumau pai
Ahakoa he kapia ngā kapia e rua, e mōhiotia whānuitia ana ko te PET (Polyethylene terephthalate), he painga tino onge kei a PET:
He pai ngā āhuatanga miihini, ā, e 3-5 ngā wā te kaha o te pānga atu i ērā atu kiriata, ā, he pai hoki te ātete piko. He ātete ki te hinu, te ngako, ngā waikawa waimeha, ngā kawakore, me te nuinga o ngā whakarewa. Ka taea te whakamahi mō te wā roa i roto i te awhe pāmahana o te 55-60 ℃, ka taea te tu atu i ngā pāmahana teitei o te 65 ℃ mō ngā wā poto, ā, ka taea te tu atu i ngā pāmahana iti o te -70 ℃, ā, he iti noa te pānga ki ōna āhuatanga miihini i ngā pāmahana teitei me te iti.
He iti te uruhanga o te hau me te mamaoa wai, ā, he tino ātete ki te hau, te wai, te hinu, me te haunga. He tino mārama, ka taea te aukati i ngā hihi ultraviolet, ā, he pai te kanapa. Kāore he paitini, kāore he haunga, he pai te akuaku me te haumaru, ka taea te whakamahi tika mō ngā takai kai.
Mō te whakamahinga o te kiriata whakarerekētanga tae, he pai te maeneene o te kiriata whakarerekētanga tae PET, he pai te pānga whakaatu ina piri ki te motuka, ā, kāore he tauira kiri karaka tuku iho ina piri. He paipa hau honikoma te kiriata whakarerekētanga tae PET, he watea mō te hanga, ā, he uaua ki te whakakore. I te wa ano, he tino pai te ātete ki te ngenge, te ātete ki te waku, me te pumau o te āhua.
TPU: Mahi teitei, tiaki uara nui ake
Ko te TPU (Thermoplastic polyurethanes), e mōhiotia ana ko te rapa elastomer polyurethane thermoplastic, he rauemi polymer i hangaia mā te hononga me te polymerization o ngā momo ngota iti. He tino pai ngā āhuatanga o te TPU o te kukū teitei, te kaha kukū teitei, te pakari, me te ātete ki te koroheketanga, e hanga ana hei rauemi pakari me te hoa taiao. Ko ngā painga: he pakari pai, he ātete ki te kakahu, he ātete ki te makariri, he ātete ki te hinu, he ātete ki te wai, he ātete ki te koroheketanga, he ātete ki te āhuarangi, me ētahi atu. I te wa ano, he maha ngā mahi tino pai pēnei i te ātete wai teitei, te uruhanga makuku, te ātete ki te hau, te ātete ki te makariri, te ārai huakita, te ātete ki te pokepokea ai, te tiaki i te mahana, te ātete ki te UV, me te tuku pūngao.
I ngā rā o mua, i hangaia te TPU mai i te rauemi kākahu motuka e kore e kitea, koinei te rauemi pai rawa atu mō te kiriata motuka. Kua whakamahia inaianei te TPU ki te ao o ngā kiriata whakarerekē tae. Nā te uaua o te tae, he nui ake te utu, ā, he iti ake ngā tae. I te nuinga o te wā, he āhua hoha noa iho ōna tae, pērā i te whero, te mangu, te hina, te kikorangi, me ētahi atu. Ka riro hoki i te kiriata whakarerekē tae o te TPU ngā mahi katoa o ngā koti motuka e kore e kitea, pērā i te whakatika i ngā karawarawa me te tiaki i te peita motuka taketake.
Ko te whakataurite i te mahi, te utu, me ngā rauemi o ngā kiriata whakarerekētanga tae i hangaia ki te PVC, PET, me ngā rauemi TPU e whai ake nei: Te whakataurite kounga: TPU>PET>PVC
Rahinga Tae: PVC>PET>TPU
Awhe utu: TPU>PET>PVC
Mahi hua: TPU>PET>PVC
Mai i te tirohanga o te roa o te ora, i raro i ngā āhuatanga me te taiao ōrite, ko te roa o te ora o te PVC he tata ki te 3 tau, ko te PET he tata ki te 5 tau, ā, ko te TPU he tata ki te 10 tau.
Mena kei te whai koe i te haumaru me te tumanako ki te tiaki i te peita o te motuka mēnā ka pā mai he aituā, ka taea e koe te whiriwhiri i te kiriata TPU huri tae, te pania rānei he paparanga kiriata PVC huri tae, kātahi ka pania he paparanga PPF.
