Kuzindikira Kukhazikika kwa PVC: Udindo wa calcium-zinc ndi njira zotsogola

Polyvinyl chloride (pvc), amodzi mwa a thermoplastics kwambiri, ndi yosakhazikika ikaonekera kumoto, ma radiation a UV, kapena kupsinjika kwamakina pakukonzekera ndi kugwiritsa ntchito. Kutsutsa kuwonongeka, okhazikika ndi zowonjezera zotsutsa. Mwa izi, calcium-zinc (ca-zn) zokhazikika ndi zotsogola zomwe zikuyimira zikuyimira njira ziwiri zosiyana, iliyonse yomwe ili ndi zovuta zapadera komanso zovuta.

1.

Okhazikika otsogola, monga dibosic kutsogolera carbonate kapena kutsogolera osasunthika, adakondweretsedwa chifukwa cha mphamvu zawo komanso kukhazikika kwa kutentha. Iwo ali ndi vuto la hydrochloric acid (hcl) kumasulidwa mu PVC kuwonongeka kwa PVC, kupewa kuwonongeka kwa autocatalyc. Komabe, kuwopsa kwawo komanso zoopsa zachilengedwe zadzetsa malamulo owonetsera. Mwachitsanzo, kutsatira lamulo la European Union (EU) 2023/293 Kuletsa Zotsogolera ku PVC mpaka <0.1%, ndikuthamangitsa njira zotetezeka.

2. Kukhazikika kwa calcium-ZicKin: Njira Yochezera Eco

Kukhazikika kwa calcium-zinc, kopangidwa ndi mchere wa calcium ndi zicc ophatikizidwa ndi acids organic, kuthana ndi zovuta zachilengedwe komanso zaumoyo. Ndiwopanda kupweteka, kutsatira malamulo apadziko lonse lapansi (mwachitsanzo, kufikira ndi rohs), ndikugwirizanitsa zolinga zokhazikika. Ubwino wofunikira umaphatikizapo:

- Kukhazikika: Pewani kuwonongeka kwa mafuta pakusintha kwa kutentha kwambiri (mwachitsanzo, podutsa kapena kuwumba jekeseni).

-Uv kukana: Tetezani zinthu za PVC ngati masitepe a zenera ndi zingwe zakunja kuchokera ku Sungunuka ndi nyengo.

-Achinthu chambiri: Kupezeka m'masukulu apadera, monga chakudya cholumikizira chakudya, chotsika kwambiri, komanso chowoneka bwino, ndikuloza kwa mafakitale osiyanasiyana monga zomanga, ndikuyika.

3.. Magwiridwe antchito ndi zochitika pamsika

Ngakhale okhazikika otsogola kuwonetsa bwino kwambiri kutentha kwa matenthedwe, makina a calcium-zinc atseka magwiridwe antchito kudzera pakupanga maulendo apamwamba. Mwachitsanzo, ma syrnergies okhala ndi okhazikika a co-okhazikika ngati mchere wa acid. Msika Wapadziko Lonse Wokhazikika PVC, yamtengo wapatali pa $ 3.48 biliyoni mu 2023, ikuchitika kuti ifikire $ 433 biliyoni ndi 2030 biliyoni, zopangidwa ndi zopanga zokhala ndi mafuta a kanjedza.

4. Mapulogalamu ndi Maganizo Amtsogolo

Kupanga ma calcium-zinnn okhazikika poyendetsa ntchito zofuna chitetezo ndi kukhazikika:

-Kona kutengeza: Mapaipi, mafelemu a pawindo, ndi kufupikitsa.

-Autoomative: Mitundu ndi zisindikizo.

-Ngati yoyendetsa: mafilimu ogwirizana ndi zotengera. Zopitilira R & D imayang'ana pakukonza mtengo wopatsa mphamvu komanso kukulitsa milandu, monga njira yosinthira ya mawonda ndi zida zamankhwala.

Mapeto

Kusintha kuchokera ku liwongo la calcium-zinc kumatsimikizira kudzipereka kwa makampani a PVC kukhazikika. Ngakhale zovuta monga mtengo wokwera kwambiri zikupitilira, kukhazikika kwa chilengedwe, komanso magwiridwe antchito osiyanasiyana - khazikikeni njira za calcium-zinc monga tsogolo la PVC ngati tsogolo la PVC. Monga momwe materinono amasinthira, okhazikikawa amatenga mbali yofunika kwambiri popereka zinthu zobiriwira.
