Kei tua atu i te hiako me te PVC: Kitea he rauemi hou mō ngā taupoki wira me ngā taputapu kore-paheke, whakamarie hoki!

He aha ngā take e tūpono ai te haumaru me te whakamarie o ngā kōwhiringa hipoki tawhito?

Hiako tūturu,He mea tuku iho, he mea rongonui hoki te hiako kounga teitei, e kitea ana i roto i ngā waka katoa mai i te waka waenga ki ngā waka papai. Ahakoa he āhua tawhito, he āhua papai hoki, he ngoikoretanga anō hoki ōna.Ko te āwangawanga matua mō te haumaru ko tōna ngaronga nui o te pupuri ina mākū, ina haukū rānei i te werawera., ka pahekeheke te urungi, ā, ka raru pea te tika o te urungi, inā koa i ngā wā tino kino. I roto i te wā, ka pakaru te hiako i te wā e pāngia ana e te waku, te werawera, me te hinu, ka kanapa, ka pahekeheke, ka whakaiti i tōna āhua papai me ōna āhuatanga haumaru.

Polyurethane (PU) Polyvinyl Chloride (PVC) rāneiHe mea noa ngā hiako hangai hei whakakapi i te utu. Heoi, ko ngā kōwhiringa kounga iti, inā koa ko ērā e whakamahi ana i te PVC, tera pea kei roto ngā matū whakapūmau pērā i te phthalates. Ina wera te roto o te motuka, ka taea e ēnei matū te mimiti, ka puta te "kakara motuka hou" me te tuku pea i ngā kakara kino, whakarihariha rānei. Hei tāpiri, ko te nuinga o ngā rauemi PU/PVC kāore e taea te manawa. Mā tēnei korenga o te manawa ka hua ake he ringaringa mākūkū me te pahekeheke i te wā taraiwa raumati, ahakoa he hauhautanga, ka whakararu i te whakamarie me te wheako taraiwa kounga teitei.

Ngā Elastomers Thermoplastic (TPE)Ahakoa he ngāwari, he ngāwari hoki ētahi, he iti noa iho ō rātou herenga mō ngā mahi motuka. Ko tētahi ngoikoretanga matua ko te iti o te ātete ki te rakuraku me te ngoikore o te mahi tawhito i raro i ngā pāmahana teitei. Mā te roa o te wā e pāngia ana e te hihi UV kaha o te raumati me te ozone i roto i te kāpata ka piri, ka whakapakeke, ka memeha te tae, ka ngaro rānei te ngāwari o te rauemi. Ehara i te mea ka pā noa tēnei pirau ki te whakamarie o te pupuri engari ka tūpono hoki he mōrearea haumaru i roto i te wā.
