Waituhi tā waituhiKo te whiriwhiri i ngā rauemi, te taiao, me ngā whakaritenga ture te mea nui. Mā te whiriwhiri i te mangumangu hē ka puta he raruraru pēnei i te memeha me te pakarukaru o ngā waehere tae atu ki ngā whakahokinga hua, ā, he nui ake ngā utu i ngā penapena i ngā taonga pau.
Ko te haumaru me te tutuki i ngā whakaritenga te kaupapa matua o te umanga kai me te inu.
Ko te GB 4806.14-2023, i tukuna i te tau 2023, koia te paerewa ā-motu tuatahi o tōku whenua mō ngā waituhi e whakamahia ana i roto i ngā rauemi e pā ana ki te kai. Me whakarite te whiriwhiri waituhi kia tutuki i tēnei paerewa. He maha ngā wā ka tūpono ngā raina whakaputa inu ki te haukū i runga i ngā pounamu, e hiahiatia ana he "waituhi pounamu mākū" ka taea te uru ki roto i ngā kiriata wai me te piri, ka āwhina i te horoi i te wā hangarua. Me whakamahi ngā waituhi ātete pāmahana iti mō ngā kai tio hei ārai i te wehenga i te wā o te mekameka makariri.
te paerewa ā-motu tuatahi o tōku whenua mō ngā waituhi e whakamahia ana i roto i ngā rauemi e pā ana ki te kai
He tino tiketike ngā whakaritenga a ngā umanga rongoā me ngā ahumahi whakapaipai mō te pakari o ngā tapanga.
Ko ngā waituhi kanapa kore e kitea e whakamahia whānuitia ana hei ārai i te tinihanga me te whai i ngā mea e hiahiatia ana; kāore e kitea i raro i ngā āhuatanga noa engari ka puta te tae i raro i te mārama ultraviolet. Hei tāpiri, nā te mea he maha ngā wā ka pāngia e te waipiro hei patu huakita, me whiriwhiri ngā waituhi ātete-ethanol kia kore ai e horoia te waituhi.
te paerewa ā-motu tuatahi o tōku whenua mō ngā waituhi e whakamahia ana i roto i ngā rauemi e pā ana ki te kai
Ko te hanga o ngā wāhanga hiko me ngā wāhanga motuka ka pāngia e te pāmahana tiketike, te waikura matū rānei.
Ko te hanga papa ara iahiko me whakamahi i ngā waituhi motuhake e ātete ana ki te UV, ka tere te whakamaroke mā te hihi ultraviolet, ā, ka taea te tu atu ki roto i ngā waituhi whakairo. Ko ngā wāhanga uku me ngā wāhanga whakarewa e whakamahi ana i ngā waituhi ātete pāmahana teitei ka taea te tu atu i ngā pāmahana neke atu i te 1300°C me te kore e memeha te tae.
Waituhi motuhake ātete-UV
He maha ngā momo rauemi e whakamahia ana i roto i te umanga tākai me ngā rauemi hanga.
He iti te kaha o te mata o ngā mata pēnei i ngā waea me ngā taura, me ngā paipa kirihou, ā, he uaua ki te piri, me whakamahi waituhi whakarewa piri-teitei. Ka kaha te piri o ēnei waituhi ki ngā rauemi pēnei i te PE me te PP. Mō ngā rauemi pūwero pēnei i ngā pouaka kātene, he rawaka ngā waituhi wai, hinu rānei, he iti te utu, ā, he pai hoki mō te taiao.
Kāore e taea te whakawhiti i ngā tawhā waituhi (pēnei i te matotoru me te kawe hiko) mō ngā waitohu rerekē o ngā pūreretā waituhi; mā te whakaranu i ēnei ka kino pea te taputapu. I te wā e whiriwhiri ana i te waituhi, me whakarite tonu te tauira i tūtohutia e te kaihanga taputapu, me te tono i ngā pūrongo MSDS me ngā whakamātautau tutuki.
Pūreretā waituhi OBOOCKa whakamahia e ngā kātere ngā rauemi mata tae kawemai, hei whakarite i te pumau o te waituhi, ā, he tere te maroke me te piri pai. He pai mō ngā rauemi kore-ā-roto pērā i ngā konganuku, ngā kirihou, me ngā putea PE, ka tautoko i te tānga whakamāramatanga teitei i te 600x600 DPI, he roa te wā whakatuwheratanga o te taupoki, ā, he iti ake te tūponotanga ki te aukati, ka whakaiti i ngā utu tiaki mō te wā kore mahi.
