Ngā Whakaaro Haumaru me ngā Ture mō te DOP me te DOTP
Ko te DEHP, te matū e hokona ana hei DOP, kei runga i te Rārangi Kaitono me te Rārangi Whakamanatanga a te Tari Matū Pākehā nā te paitini uri me ngā āhuatanga whakararuraru endocrine. Kei raro hoki i ngā here i roto i ngā kāwai hua motuhake o te EU. Ko te EU RoHS Directive e whakawhāiti ana i te DEHP i roto i ngā rauemi ōrite e whakamahia ana i roto i ngā taputapu hiko me te hikohiko, kei raro i te whānuitanga me ngā whakawāteatanga.
I te Hononga o Amerika, ka aukatia e te Komihana Haumaru Hua Kaihoko ngā taonga takaro a ngā tamariki me ngā taonga tiaki tamariki kei roto i te neke atu i te 0.1% DEHP i roto i tētahi wāhanga kirihou e wātea ana. He rerekē ngā here, ngā whakawāteatanga, ngā ture tuhinga me ngā ture whakamātautau a ētahi atu whenua me ngā kāwai hua.
He rerekē te tuakiri matū me te āhua ture o te DOTP, engari mā te whakamahi i te DOTP, kāore e 'haumaru' aunoa te hua kua oti, 'kai', 'haumaru hauora', 'haumaru taonga takaro', 'kore phthalate', 'tutuki REACH' 'tutuki RoHS' rānei.

Ngā Tohutoro Mana
Ngā Pātai Auau mō te DOP me te DOTP
He aha te rerekētanga i waenga i te DOP me te DOTP?
Ko te DOP he DEHP, he mea hanga kirihou orthophthalate. Ko te DOTP he DEHT, he mea hanga kirihou terephthalate. E whai uara ana te DOP mō te whai huatanga me te utu o te hanga kirihou kua whakapumautia, ko te DOTP ia e tīpakohia ana mō te iti o te piki me te heke, te pumau ake, te ātete ki te heke, ngā āhuatanga hiko me te tūnga kore-orthophthalate.
He rite tonu te rauemi o te DOP me te DEHP?
I te whakamahinga arumoni noa, ko te DOP e pā ana ki te DEHP, ki te bis(2-ethylhexyl) phthalate rānei, CAS 117-81-7. Nā te mea he rerekē ngā whakarāpopototanga, me whakaū te ingoa matū katoa me te tau CAS i mua i te hoko.
He rite tonu te mea whakapūkara o te DOTP me te DEHT?
Āe. Ko te DOTP me te DEHT ngā ingoa noa mō te bis(2-ethylhexyl) terephthalate, CAS 6422-86-2. Mā te DEHT ka tautuhia te hanganga 2-ethylhexyl terephthalate kia tika ake.
He mea hanga kirihou kore-phthalate te DOTP?
Ko te DOTP e hokohokohia whānuitia ana hei non-phthalate nā te mea ehara i te orthophthalate pērā i te DEHP. Ko te 'Non-orthophthalate plasticizer' te whakaahuatanga matū tika ake. Ko tētahi kereme kore-phthalate mō tētahi hua kua oti me tautoko e tētahi whakatakotoranga kua tautuhia me te tikanga whakamātautau.
He haumaru ake te DOTP i te DOP?
He whānuitia te whiriwhiri i te DOTP hei huarahi kē atu nā te mea kei raro i ngā here ture nui a te ture te DEHP. Heoi, ko te haumaru e whakawhirinaki ana ki te tūponotanga, te pānga, te parakore, te horopeta me te whakamahinga e whakaarohia ana. Kāore he mea hanga kirihou e tika ana kia kiia he haumaru whānui me te kore he taunakitanga mō te whakamahinga motuhake.
Ka taea e te DOTP te whakakapi tika i te DOP?
Ka taea e te DOTP te whakakapi i te DOP i roto i ngā momo PVC ngāwari maha, engari kāore e taea te kī taurangi he whakakapinga takitahi. Me whakarerekē pea te inenga, ngā mea whakaū, ngā whakakī, te pāmahana tukatuka me te wā hanumi. Whakaotia ngā whakamātautau taiwhanga me te whakaputa i mua i te whakakapinga tauine katoa.
He pai ake te ātete wera o te DOTP i te DOP?
He maha ngā wā ka tīpakohia te DOTP mō te iti o te piki me te pai ake o te mahi whakatōtō wera, engari ko te matū PVC katoa te mea e whakatau ana i te hua whakamutunga. Whakaūtia te mahi mā te whakaiti taumaha, te pupuri-kume, te pupuri-toronga me ngā whakamātautau whakatōtō motuhake ki te tono.
He pai te DOTP mō te whakamahana waea me te taura?
He mea whakamahi noa te DOTP i roto i ngā hononga waea me ngā taura PVC ngāwari nā te mea ka taea e ia te whakarato i te ārai hiko whai hua, te ngāwari me te pumau. Me tutuki tonu te hononga kua oti i ngā paerewa taura e hiahiatia ana, te whakatauranga pāmahana, ngā whakamātautau hiko, ngā whakamātautau tawhito me ngā whakaritenga mura.
He pai te DOTP mō te PVC e pā ana ki ngā kai?
Kāore te pai o te kai e puta aunoa. Me tutuki i te tohu DOTP motuhake me te taonga kua oti te hanga ngā rārangi pai e tika ana, ngā herenga hanganga, ngā herenga hekenga, ngā momo kai, te wā pa atu me ngā āhuatanga pāmahana i te mākete ūnga.
Ka taea te whakamahi i te DOP i roto i ngā hua hauora?
He whakamahinga hauora tawhito tō te PVC kua whakakikoruatia ki te DEHP, engari ko aua whakamahinga ka uru pea ki te aromatawai mōrearea, te tapanga, te whakaaturanga me ngā whakaritenga ture. Kaua rawa te DOP whānui e hokohokohia hei tohu hauora me te kore he tuhinga mō te rauemi, te taputapu me te mākete tuturu.
He aha ngā tuhinga e tika ana kia tonoa e ngā kaihoko mai i tētahi kaiwhakarato kirihou?
Tonoa te SDS, TDS, COA, te ingoa matū, te tau CAS, ngā whakatakotoranga parakore me ngā whakapuakitanga ture e tika ana. Mō ngā whakamahinga tairongo, tonoa ngā pūrongo whakamātautau matū here, hekenga, hua oti rānei a te hunga tuatoru e ōrite ana ki te mākete ūnga.
Whakatau: Ko tēhea Plasticizer hei Kōwhiri māu?
Ka taea e te DOP me te DOTP te whakakirikiri i te PVC ngāwari, engari he rerekē ngā kaupapa matua mō te hoko me te mahi. Tērā pea ka whai hua tonu te DOP mō ngā hua ahumahi kua whakaaetia, he iti te utu. Ko te DOTP te kaitono tīmatanga kaha ake ina he mea nui te pumau, te mahi hiko, te ātete hekenga, te roa o te ratonga, te whakatakotoranga kore-orthophthalate rānei.
Ko te kōwhiringa pai rawa atu e whakawhirinaki ana ki te pakeke o te ūnga, te tukanga, te pāmahana ratonga, te taiao tango, te roanga o te ora, te mākete ūnga me te whakamātautau e hiahiatia ana. Arotakehia ngā tuhinga hangarau me te whakamana i te matū PVC katoa i mua i te hanga arumoni.
Mō te āwhina i te whiriwhiri i te pepa PVC, i te kiriata PVC ngāwari rānei, Whakapā atu ki a HSQY Plastic me te momo hua, te matotoru, ngā ine, te ngāwari, te tikanga tukatuka, te pāmahana ratonga, te mākete ūnga me ngā whakaritenga tutuki i ngā whakaritenga.
