Ngā Whakapūmau PVC Konutea Pāriuma Waihe tāpiri motuhake e whakamahia ana i roto i te tukatuka polyvinyl chloride (PVC) hei whakarei ake i te pumau o te wera me te mārama, hei ārai i te pirau i te wā e hangaia ana, hei whakaroa hoki i te roa o te oranga o te rauemi. Anei tētahi whakamārama taipitopito o ō rātou hanganga, ngā tono, ngā whakaaro ture, me ngā au o te mākete:
Te Hanganga me te Tikanga
Ko ēnei mea whakaū he mea hanga mai i ngā tote barium (hei tauira, te alkylphenol barium, te 2-ethylhexanoate barium rānei) me ngā tote konutea (hei tauira, te 2-ethylhexanoate konutea), me ngā wāhanga mahi tahi pēnei i te phosphites (hei tauira, te tris(nonylphenyl) phosphite) mō te chelation me ngā whakarewa (hei tauira, ngā hinu kohuke) mō te marara. Ka whakaratohia e te barium te tiaki wera mō te wā poto, ko te konutea ia ka tukuna te pumau mō te wā roa. Mā te āhua wai ka whakarite kia ōrite te ranunga i roto i ngā whakatakotoranga PVC. Kei roto hoki i ngā whakatakotoranga hou ngā esters phosphate silicone polyether hei whakapai ake i te hinu me te mārama, ka whakaiti i te mimiti wai i te wā whakamatao.
Ngā Painga Matua
Kore-paitiniKāore he konganuku taumaha pērā i te cadmium, ā, e tutuki ana i ēnei ngā paerewa whakapā-kai me ngā paerewa hauora (hei tauira, ngā paerewa kua whakaaetia e te FDA i roto i ētahi hanganga).
Te Whai Hua o te TukatukaMā te āhua wai ka māmā te horapa ki roto i ngā matū PVC ngohengohe (hei tauira, ngā kiriata, ngā waea), ka whakaiti i te wā tukatuka me te whakapaunga pūngao.
Te Whai Hua o te UtuHe whakataetae ki ngā whakaū tine waro, me te karo i ngā āwangawanga paitini.
Ngā Pānga WhakakotahiIna honoa ki ngā whakaū konupūmā-konutea, ka whakatikahia ngā take "whakakorikori arero" i roto i te whakaputanga PVC mārō mā te whakataurite i te hinu whakahinuhinu me te pumau wera.
Ngā tono
Ngā Hua PVC NgāwariE whakamahia whānuitia ana i roto i ngā kiriata ngāwari, ngā taura, ngā hiako horihori, me ngā taputapu hauora nā te mea kāore e paitini, ā, he mārama hoki te mau.
PVC pakari: I te taha ongā kaiwhakaū konupūmā-konutea, ka whakapai ake i te ngāwari o te tukatuka i roto i ngā kiriata me ngā kōtaha, ka whakaiti i te "arero" (te paheke o te rauemi i te wā e tangohia ana).
Ngā Taupānga MotuhakeHe whakatakotoranga mārama-teitei mō ngā takai me ngā hua ātete-UV ina honoa ki ngā antioxidants pēnei i te 2,6-di-tert-butyl-p-cresol.
Ngā Whakaaroaro Ture me te Taiao
Te Whakatutukitanga o REACHKo ngā matū barium kei raro i te REACH, me ngā here mō te barium wairewa (hei tauira, ≤1000 ppm i roto i ngā hua kaihoko). Ko te nuinga o ngā whakaū konutea barium wai ka tutuki i ēnei here nā te iti o te wairewatanga.
Ngā Huarahi kē atuKei te piki haere te rongonui o ngā whakaū konupūmā-konutea nā runga i ngā ture taiao pakari ake, inā koa i Ūropi. Heoi anō, kei te pai tonu ngā whakaū konutea barium mō ngā tono wera nui (hei tauira, ngā wāhanga motuka) ina kore e ranea te konupūmā-konutea anake.
Ngā Raraunga Mahi me te Hangarau
Te Pūmautanga o te Wera: E whakaatu ana ngā whakamātautau wera pūmau i te pumau roa (hei tauira, 61.2 meneti i te 180°C mō ngā whakatakotoranga me ngā kaiwhakaū-tahi hydrotalcite). Ka whai hua te tukatuka hihiri (hei tauira, te extrusion takirua-whiu) mai i ōna āhuatanga whakahinuhinu, ka whakaiti i te pakaru kutikuti.
MāramatangaKo ngā whakatakotoranga matatau me ngā ester silicone polyether ka tutuki i te māramatanga whatu teitei (≥90% te whakawhiti), ā, he pai mō ngā kiriata takai.
Te Ātete ki te HekengaHe iti te hekenga o ngā mea whakau i hangaia tika, he mea nui mō ngā mahi pēnei i te takai kai ina he āwangawanga te hekenga o ngā tāpiringa.
Ngā Tohutohu Tukatuka
HototahitangaĀraia te whakamahi nui rawa i ngā hinu whakahinuhinu waikawa stearic, nā te mea ka tauhohe pea ēnei ki ngā tote konutea, ka tere ake te pirau o te PVC. Kōwhiriangā kaiwhakaū tahipērā i te hinu pīni soya kua whakapūkaratia hei whakarei ake i te hototahitanga.
InengaKo te whakamahinga noa kei waenga i te 1.5–3 phr (ngā wāhanga mō ia rau kapia) i roto i te PVC ngohengohe me te 0.5–2 phr i roto i ngā hanganga pakari ina honoa ki ngā whakau konupūmā-konutea.
Ngā Auahatanga o te Mākete
Ngā Ārahi TipuKo te hiahia mō ngā whakaū kore-paitini i Āhia-Moana-nui-a-Kiwa me Amerika Te Raki kei te akiaki i ngā auahatanga i roto i ngā hanganga konutea barium. Hei tauira, kei te piki haere te whakamahi a te umanga PVC o Haina i ngā whakaū konutea barium wai mō te hanga waea/taura.
Ngā WeroKo te pikinga ake o ngā whakaū konupūmā-konutea (e matapaetia ana he CAGR o te 5–7% i roto i ngā rāngai rauemi hu me ngā rāngai takai) he whakataetae, engari kei te mau tonu te konutea barium i tōna tūranga i roto i ngā tono mahi-teitei.
Ka tukuna e ngā Whakapūmau PVC Konutea Pīni Wai he taurite o te whai huatanga utu, te pumau wera, me te tutuki i ngā ture, ā, he mea nui rawa atu ēnei i roto i ngā hua PVC ngohengohe me ngā hua PVC pakari-haurua. Ahakoa te akiaki a ngā pēhanga taiao i te nekehanga ki ngā momo whakakapinga konupūmā-konutea, ka whakarite ō rātou āhuatanga ahurei kia mau tonu te hiranga i roto i ngā mākete motuhake. Me āta whakataurite e ngā kaihanga ngā whakaritenga mahi me ngā aratohu ture kia nui ake ai ō rātou painga.
