Musi wa4 Nyamavhuvhu 2020, mutemo mutsva wekudzivirira ma diisocyanates pasi pe REACH wakagamuchirwa nevakuru vekuEurope, uchitarisa kukanganiswa kwekufema neganda kunogona kukonzerwa nema diisocyanates.

Chidzidzo chitsva chine chinangwa chekugadzira nzira dzekuyedza dzekuyera kubvumidzwa kwemvura kubva pamufananidzo: quimono - Pixabay (mufananidzo wechiratidzo).
REACH (Kunyoresa, Kuongorora, Kubvumidza uye Kudzora Makemikoro) mutemo weEuropean Union, wakagamuchirwa kuvandudza dziviriro yehutano hwevanhu nenharaunda kubva panjodzi dzinogona kukonzerwa nemakemikari, ukuwo uchisimudzira kukwikwidzana kweindasitiri yemakemikari yeEU.
Zvinonamira zvePolyurethane (PU) uye zvinonamira zvakachengeteka kushandiswa muzvigadzirwa zvakawanda mumaindasitiri akasiyana-siyana, akadai semotokari, fenicha, kuvaka, uye kurongedza. Kugadzirwa kwepolyurethanes kunoda aromatic kana aliphatic diisocyanates. Izvi zvakachengeteka kana zvikashandiswa zvichienderana nematanho ekuchengetedza akatarwa. Mukugadzirwa kwePU, ma diisocyanates, achisangana nepolyols, anotoshandiswa zvekuti haapo muzvigadzirwa zvepolyurethane zvakapedzwa. Muganho uyu haurambidze kushandiswa kwezvinonamira zvepolyurethane uye zvinonamira, asi unoratidza zvinodiwa zvekudzidziswa kuti zvishandiswe zvakachengeteka. Zvinonamira zvePU uye zvinonamira zvicharamba zvichishandiswa zvakanyanya nekuda kwekushanda kwadzo kwakasiyana-siyana uye sezvo pasina mamwe matekinoroji aripo anogona kugadzira zvigadzirwa zvine hunhu hwese hwePU.
Mutemo weREACH EC/1907/2006 unotarisa kugadzirwa nekushandiswa kwezvinhu zvemakemikari, pamwe nemhedzisiro yazvo pahutano hwevanhu nenharaunda. Muganho weREACH we4 Nyamavhuvhu 2020 unotsanangura kudiwa kwekudzidziswa uye kunyorwa mazita kune vashandisi vemaindasitiri kana vehunyanzvi ve diisocyanates (munhu mumwe nemumwe kana musanganiswa) vane huwandu hwe monomeric hunopfuura 0.1% nehuremu. Muganho uyu unoshanda kune chero chiitiko apo kusangana ne diisocyanates kunogona kuitika. Hazvishande kune zvigadzirwa zvePU zvinoshandiswa nevatengi. Muganho wakasiyana maererano nezvigadzirwa zvevatengi watoitwa.
Zvinodiwa zvekudzidziswa zvinosungirwa
Vashandisi vema diisocyanate vane hunyanzvi uye maindasitiri ndivo vachava nebasa rekuona kuti kudzidziswa kwacho kwapera ivo nevashandi vavo. Vatungamiriri, zvakare, vachada kudzidziswa. Kunyange zvazvo vatengesi vane basa rekuzivisa vashandisi nezvekudiwa kwekudzidziswa, havasi ivo vane basa rekudzidzisa vashandi. Hapana humbowo hunodiwa kubva kuvashandisi kuenda kuvatengesi maererano nekugamuchira ruzivo. Vatengesi vanofanira kuzivisa vatengi vavo ruzivo rwavanogamuchira kubva kuvatengesi.
Kudzidziswa uye chitupa, zvinosanganisira kupasa bvunzo, zvinofanira kunge zvapera musi wa24 Nyamavhuvhu 2023. Zvinyorwa zvekudzidziswa kunopiwa vashandi zvinofanirwa kuchengetwa nevashandirwi. Makore mashanu ega ega, kuvandudzwa kwekudzidziswa kuchave kwakakosha. Kune matanho matatu ekudzidziswa anoenderana nemazinga akasiyana enjodzi. Saka, zviri mukudzidziswa kunodiwa nemunhu wese zvinoenderana nemazinga enjodzi yaanosangana nayo.
Puratifomu itsva yekudzidzira yePU
FEICA, pamwe chete neEuropean Diisocyanate & Polyol Producers Association (ISOPA), European Aliphatic Isocyanates Producer Association (ALIPA), nedzimwe nzvimbo dzakawanda dziri muindasitiri yepolyurethane, vanga vachishanda nesimba kuronga chirongwa chekudzidzisa chakazara kuti vave nechokwadi chekuti ma diisocyanates anoshandiswa zvakachengeteka kune vagadziri nevashandisi vane hunyanzvi muEurope yese. Nenzira iyi, FEICA inovimbisawo kuti vese vanoshandisa ma PU ane manamatisi nezvisimbiso muEurope yese vanoramba vachibata ma diisocyanates zvakachengeteka. Puratifomu yekudzidzisa yakatangwa muChirungu muna Mbudzi 2021. Kubva 1 Zvita ichave iripo muchiGerman.
Puratifomu iyi ichave inowanikwa muEU yese, uye zvese zvekudzidzisa zvichave zviripo mumitauro yese yeEU pakati pegore ra2022. Vhoucha yekudzidziswa mahara kune vese vanoshandisa maadhesives eEuropean PU uye ma sealant inowanikwa pa www.feica.eu. Pamusoro pezvo, zvekudzidzisa zvichave zviripo pakudzidziswa kwemunhu mumwe nemumwe mukirasi.
Zvisungo zveKunyora Mazita
Kubva musi wa24 Kukadzi 2022, mutongo/chinyorwa chinofanira kuoneka pazvigadzirwa kuti zvishandiswe mumaindasitiri kana mumabasa ane huwandu hwe monomeric hunopfuura 0.1% nehuremu. Mutongo wacho unogona kuverengwa seizvi: “Kubva musi wa24 Nyamavhuvhu 2023, kudzidziswa kwakakwana kunodiwa usati washandisa chigadzirwa ichi mumaindasitiri kana nehunyanzvi.” Muganho weREACH wa4 Nyamavhuvhu 2020 haupe rumwe ruzivo nezvezvinhu zviri muchinyorwa ichi (semuenzaniso saizi, nzvimbo, kana mutauro). Tinokurudzira zvikuru mapato ese ane chekuita nazvo kuti atange kugadzira hurongwa hwekunyorwa kwechinyorwa nekukurumidza uye kutarisa webhusaiti yeFEICA nguva nenguva kuti vagadzirise.
