1、 Whakamāramahia ngā āhuatanga tono me ngā whakaritenga mahi
1. Ngā Hua Kai/Rongoā
Whakatairangahia te whakamahinga o ngā whakaū organotin (mercaptan methyl tin), e tutuki ana i ngā paerewa FDA, ā, he mārama teitei, e tika ana mō ngā hua PVC mārama, ngā kiriata takai kai, me ētahi atu; Ko ētahi atu kōwhiringa ko ngā whakaū hiato konupūmā konutea, me whai tiwhikete e REACH, LFGB, me ētahi atu paerewa hei whakatutuki i ngā whakaritenga hekenga kore-paitini.
2. Ngā Rauemi Hanga/Ahumahi
Ngā paipa me ngā pereti mārō: E taunakihia ana kia whakamahia ngā whakau matū tote mata (he iti te utu, he teitei te pumau o te wera), engari me aro ki ngā herenga taiao.
2. Arotakehia ngā ture taiao me te haumaru
1. Te tutuki i ngā whakaritenga taiao:
E hiahiatia ana ngā kaiwhakaū kore-mata me kore-cadmium pērā i te konupūmā konutea hiato, ngā kaiwhakaū organotin rānei, hei kaweake ki te Kotahitanga o Ūropi, ki ngā mara hauora rānei.
Āta karohia ngā rongoā whakau tote mata (he nui te paitini) me te whiriwhiri i ngā hua e tutuki ana i ngā paerewa ROHS me REACH.
2. Haumaru whakapā: Me manatoko te tere hekenga o ngā whakau mō ngā rauemi takai kai, ā, me pai ake ngā tātai hiato taumaha-ngota teitei.
3, Te whakataurite i te hangarau tukatuka me te pūnaha whakahinuhinu
1. Te whakarerekētanga o ngā tikanga tukatuka
Te whakarewa/werohanga: Me whakakotahi ngā whakaū tine waro ki te pūnaha whakahinuhinu ware piro + konupūmā stearate, ā, me whakahaere te nui o te whakahinuhinu o waho e tāpirihia ana i te 0.1-0.5 wāhanga hei karo i te marara kore taurite;
Te hurihuri/te pupuhi i te pokepoke: Me whakakotahi ngā whakaū konupūmā konutea me ngā hinu whakahinuhinu pāmahana teitei pērā i te ware pi polyethylene hei ārai i te matotoru rewa nui;
Te arotau i ngā tawhā tukanga: Ko te tukatuka i te pāmahana teitei (neke atu i te 200 ℃) me whakamahi i ngā whakaū ātete-wera (pēnei i te organotin, me ētahi atu) hei whakaiti i te taipana tihi o te rewa mā te neke atu i te 15%. Me whakahaere e ngā hua mārama te hototahitanga i waenga i ngā whakaū me ngā kapia kia kore ai e puta te ua me te pikinga o te kohu mā te 37.
4, Ngā tikanga manatoko me te whakamātautau
Whakamātautau pumau wera: Whakanohoia te tauira PVC kei roto he whakau ki te 80 ℃ mō ngā hāora 48, ka mātakitaki i te panonitanga o te tae.
Whakatauira ātete huarere: Arotakehia te pānga parenga UV mā te whakamātautau pakeketanga QUV, me te pupuri i te kaha kume neke atu i te 85% i muri i te 5000 hāora.
Manatoko mahi tukatuka: Whakamahia he rheometer taipana hei aroturuki i te rere o te rewa me te arotau i te ōwehenga o te hinu whakahinuhinu me te whakau.
