| Ngā Taupānga Matua | He whakakōkī urethane mō ngā pahuka polyurethane pakari/ngāwari;Whakateretere whakaora mō ngā paninga PU, ngā piripiri, me ngā hiri; Āwhina tukatuka i roto i te hanga kakahu me te tāonga whare |
Dimorpholinodiethyl Ether (DMDEE, CAS 6425-39-4)He whakakorikori amine tuatoru mahi-teitei te DMDEE, e mōhiotia ana e tōna tino whiriwhiringa, tōna iti o te hurihuri, me te hototahi kaha ki ngā pūnaha polyurethane (PU)—e whakanoho ana i a ia hei tāpiri matua mō te hanga ahumahi e arohia ana e te tika. He rerekē ki ngā whakakorikori amine whānui, ka tukuna e te DMDEE te whakaterenga arotahi o ngā tauhohenga hononga-urethane, e whakaiti ana i ngā tauhohenga taha me te whakarite kia rite te whakamaroke me te kore e whakararu i te hanganga o te hua, e piri pono ana ki ngā paerewa kounga me te taiao o te ao.
Ka kapi katoa ngā tono a DMDEE i ngā ahumahi uara nui: koinei te mea tino pai mō te whakaputa pahuka PU pakari me te ngāwari e whakamahia ana i roto i te whakamarumaru hanga me ngā nohoanga motuka, e whakanui ana i te ōritetanga o te pahuka me te kaha miihini; ka mahi hei whakatere whakaora tino pai mō ngā paninga PU, ngā piripiri, me ngā hiri, ka whakapoto i ngā huringa whakaputa me te whakarei ake i te roa o te here me te ātete matū; hei tāpiri, he āwhina tukatuka matua a DMDEE i roto i ngā elastomers PU motuhake mō te hanga kakahu me te hu.
Kei roto i tā mātou kohinga hua DMDEE ngā momo kua whakaritea (te momo ahumahi, te momo parakore teitei, me te momo haunga iti) kia rite ki ngā whakaritenga tono rerekē, me ngā tikanga whakahaere kounga tino pakari e whakamana ana i ngā taumata poke i raro i te 0.05% me ngā tawhā ā-tinana-matū ōrite mō ngā putanga hanganga pumau. Ka whakaratohia e mātou ngā otinga tuku ngāwari, mai i ngā kete tauira iti ki ngā tuku ipu IBC me te ipu tāke nui, me ngā tuhinga ture whānui (tae atu ki ngā MSDS reo maha, ngā tiwhikete kaipuke UN, me ngā kōnae rēhita REACH). Ka tukuna e tā mātou tīma hangarau whakatapua te tautoko takitahi—pēnei i te arotautanga hanganga PU, te whakamātautau inenga whakakorikori, me te aratohu rokiroki haumaru—hei āwhina i a koe ki te whakahaere i ngā tukanga whakaputa me te whakanui ake i te whakataetae hua.
