Pamene makampani opanga PVC akufulumira kupita ku kukhazikika ndi kuchita bwino, zinthu zokhazikika za PVC—zowonjezera zofunika kwambiri zomwe zimaletsa kuwonongeka kwa kutentha panthawi yokonza ndikuwonjezera moyo wa zinthu—zakhala malo ofunikira kwambiri pakupanga zinthu zatsopano komanso kuyang'anira malamulo. Mu 2025, mitu itatu yayikulu ikutsogolera zokambirana: kusintha mwachangu kupita ku zinthu zopanda poizoni, kupita patsogolo kwa ukadaulo wogwirizana ndi kubwezeretsanso, komanso kukula kwa malamulo okhudza chilengedwe padziko lonse lapansi. Nayi kuwunika kwakuya kwa zomwe zikuchitika mwachangu kwambiri.
Mavuto Olamulira Amatsogolera Kuwonongeka kwa Zolimbitsa Zitsulo Zolemera
Masiku a lead ndi cadmiumZokhazikika za PVCakuwerengedwa, pamene malamulo okhwima padziko lonse lapansi akukakamiza opanga njira zina zotetezeka. Malamulo a REACH a EU akhala ofunikira kwambiri pakusinthaku, ndi ndemanga zomwe zikupitilira za Annex XVII zomwe zikukonzekera kuchepetsa kwambiri lead mu ma polima a PVC kupitirira nthawi yomaliza ya 2023. Kusinthaku kwakakamiza mafakitale—kuyambira zomangamanga mpaka zida zamankhwala—kusiya zolimbitsa zitsulo zolemera, zomwe zimayambitsa chiopsezo cha kuipitsidwa kwa nthaka panthawi yotaya ndi utsi wa poizoni panthawi yowotcha.
Kudutsa nyanja ya Atlantic, kuwunika kwa US EPA mu 2025 pa zoopsa za phthalates (makamaka Diisodecyl Phthalate, DIDP) kwawonjezera chidwi pa chitetezo chowonjezera, ngakhale pazinthu zosakhazikika mosalunjika. Ngakhale kuti phthalates imagwira ntchito makamaka ngati mapulasitiki, kuwunika kwawo malamulo kwapanga zotsatira zoyipa, zomwe zapangitsa opanga kugwiritsa ntchito njira zonse "zoyera" zomwe zimaphatikizapo zokhazikika zopanda poizoni. Machitidwe olamulira awa si zopinga zokha zotsatizana - akukonzanso maunyolo ogulitsa, ndipo 50% ya msika wokhazikika wa PVC woganizira zachilengedwe tsopano umadziwika kuti ndi njira zina zosagwiritsa ntchito zitsulo zolemera.
Zolimbitsa Thupi la Calcium-Zinc Zimatenga Gawo Lalikulu
Otsogolera m'malo mwa mankhwala a heavy metal ndi awa:zokhazikika za calcium-zinc (Ca-Zn). Popeza mtengo wake ndi $1.34 biliyoni padziko lonse lapansi mu 2024, gawoli likuyembekezeka kukula pa CAGR ya 4.9%, kufika $1.89 biliyoni pofika chaka cha 2032. Kukongola kwawo kuli mu kulinganiza kosowa: kusawononga poizoni, kukhazikika kwa kutentha kwabwino, komanso kugwirizana ndi mitundu yosiyanasiyana ya PVC—kuyambira ma profiles a zenera mpaka zida zamankhwala.
Asia-Pacific ikulamulira kukula kumeneku, komwe kumabweretsa 45% ya kufunikira kwa Ca-Zn padziko lonse lapansi, chifukwa cha kupanga kwakukulu kwa PVC ku China komanso kukula kwa gawo la zomangamanga ku India. Pakadali pano, kupita patsogolo kwaukadaulo kwapereka mitundu ya Ca-Zn yogwira ntchito bwino yomwe imakwaniritsa miyezo yokhwima ya REACH pomwe ikuwonjezera magwiridwe antchito opangira. Mitundu iyi tsopano imathandizira ntchito zofunika kwambiri monga kulongedza chakudya ndi zingwe zamagetsi, komwe chitetezo ndi kulimba sizingakambirane.
Chodziwika bwino,Zokhazikika za Ca-Znzikugwirizananso ndi zolinga zachuma zozungulira. Mosiyana ndi njira zina zogwiritsira ntchito lead, zomwe zimavuta kubwezeretsanso PVC chifukwa cha zoopsa za kuipitsidwa, mitundu yamakono ya Ca-Zn imathandiza kubwezeretsanso mosavuta kwa makina, zomwe zimathandiza kuti zinthu za PVC zomwe zimagwiritsidwa ntchito pambuyo pa ogula zigwiritsidwenso ntchito kukhala ntchito zatsopano zokhalitsa monga mapaipi ndi ma nembanemba a denga.
Zatsopano mu Magwiridwe Antchito ndi Kubwezeretsanso Zinthu
Kupatula nkhawa za poizoni, makampaniwa akuyang'ana kwambiri pakukonza magwiridwe antchito a zinthu zokhazikika—makamaka pa ntchito zovuta. Mapangidwe apamwamba monga GY-TM-182 akukhazikitsa miyezo yatsopano, kupereka mawonekedwe owonekera bwino, kukana nyengo, komanso kukhazikika kwa kutentha poyerekeza ndi zinthu zokhazikika za organic tin. Kupita patsogolo kumeneku ndikofunikira kwambiri pazinthu za PVC zomwe zimafuna kumveka bwino, monga mafilimu okongoletsera ndi zida zamankhwala, komwe kukongola ndi kulimba ndikofunikira.
Zolimbitsa tin, ngakhale zikukumana ndi mavuto azachilengedwe, zimasungabe malo ake m'magawo apadera. Pokhala ndi mtengo wa $885 miliyoni mu 2025, msika wa zolimbitsa tin ukukula pang'ono (3.7% CAGR) chifukwa cha kukana kutentha kosayerekezeka m'magalimoto ndi mafakitale. Komabe, opanga tsopano akuika patsogolo mitundu ya tin "yobiriwira" yokhala ndi poizoni wochepa, zomwe zikuwonetsa udindo waukulu wokhazikika wa makampaniwa.
Chinthu china chomwe chikuchitika ndi chitukuko cha zinthu zokhazikika zomwe zimakonzedwanso kuti zigwiritsidwenso ntchito. Pamene njira zobwezeretsanso zinthu za PVC monga Vinyl 2010 ndi Vinyloop® zikuchulukirachulukira, pakufunika zinthu zowonjezera zomwe sizimawonongeka nthawi zambiri zobwezeretsanso zinthu. Izi zapangitsa kuti pakhale zatsopano mu chemistry yokhazikika yomwe imasunga mphamvu za PVC ngakhale zitakonzedwa mobwerezabwereza—chinsinsi chotseka kuzungulira kwa zinthu zozungulira.
Zatsopano Zochokera ku Bio ndi ESG
Kukhazikika sikungokhudza kuchotsa poizoni—komanso kuganiziranso za kupeza zinthu zopangira. Ma complexes atsopano a Ca-Zn ochokera ku bio-based, ochokera ku feedstocks zongowonjezwdwa, akupeza mphamvu, zomwe zimapereka mpweya wochepa kuposa njira zina zochokera ku mafuta. Ngakhale kuti ndi gawo laling'ono, ma bio-stabilizers awa akugwirizana ndi zolinga za ESG zamakampani, makamaka ku Europe ndi North America, komwe ogula ndi osunga ndalama amafunikira kwambiri kuwonekera poyera mu unyolo wopereka.
Kuyang'ana kwambiri pa kukhazikika kwa zinthu kukukonzanso momwe msika ukugwirira ntchito. Mwachitsanzo, gawo la zamankhwala tsopano limafotokoza zinthu zokhazikika zopanda poizoni pazida zodziwira matenda ndi ma phukusi, zomwe zikuyendetsa kukula kwa 18% pachaka m'gawoli. Mofananamo, makampani omanga nyumba—omwe amawerengera kufunikira kwa PVC kopitilira 60%—akuika patsogolo zinthu zokhazikika zomwe zimathandizira kulimba komanso kubwezeretsanso zinthu, kuthandizira ziphaso zobiriwira za nyumba.
Mavuto ndi Njira Yomwe Ikubwera
Ngakhale kuti zinthu zapita patsogolo, mavuto akupitirirabe. Mitengo ya zinthu zopangidwa ndi zinc yosakhazikika (yomwe imapanga 40–60% ya ndalama zopangira Ca-Zn) imapangitsa kuti pakhale kusatsimikizika kwa unyolo woperekera zinthu. Pakadali pano, kugwiritsa ntchito kutentha kwambiri kumayesabe malire a zinthu zokhazikika zomwe siziwononga chilengedwe, zomwe zimafuna kuti kafukufuku ndi chitukuko zipitirire kuti zithetse mipata yogwirira ntchito.
Komabe njira yake ndi yodziwikiratu: Zolimbitsa PVC zikusintha kuchoka pa zowonjezera zogwira ntchito kupita ku zolimbikitsa kupanga zinthu za PVC zokhazikika. Kwa opanga m'magawo monga Venetian blinds—komwe kulimba, kukongola, ndi ziyeneretso zachilengedwe zimakumana—kugwiritsa ntchito zolimbitsa izi za m'badwo wotsatira sikuti ndi chinthu chofunikira pa malamulo okha komanso mwayi wopikisana. Pamene chaka cha 2025 chikuyamba, kuthekera kwa makampaniwa kugwirizanitsa magwiridwe antchito, chitetezo, ndi kubwezeretsanso kudzatanthauzira udindo wawo pakukakamiza padziko lonse lapansi kuti zinthu zozungulira zikhale zozungulira.
