Njengoba imboni ye-PVC ishesha kakhulu ekuzinzeni nasekusebenzeni kahle, iziqinisi ze-PVC—izithasiselo ezibalulekile ezivimbela ukuwohloka kokushisa ngesikhathi sokucubungula nokwandisa isikhathi sokuphila komkhiqizo—zibe yindawo ebalulekile yokusungula izinto ezintsha kanye nokuhlolwa kwemithetho. Ngo-2025, izindikimba ezintathu eziyinhloko zibusa izingxoxo: ushintsho oluphuthumayo oluya ekwakhiweni okungenabo ubuthi, intuthuko kwezobuchwepheshe obuhambisana nokusetshenziswa kabusha, kanye nethonya elikhulayo lemithethonqubo yemvelo yomhlaba wonke. Nasi ukubuka okujulile kwentuthuko ephuthumayo kakhulu.
Izingcindezi Ezilawulayo Zibangela Ukuphela Kwezinzisi Zensimbi Enamandla
Izinsuku zokuhola kanye ne-cadmium ezisekelweIziqinisi ze-PVCzibaliwe, njengoba imithetho eqinile emhlabeni wonke isunduza abakhiqizi ezindleleni eziphephile. Umthethonqubo we-REACH we-EU ube semqoka kulolu shintsho, njengoba ukubuyekezwa okuqhubekayo kwe-Annex XVII kuhloselwe ukukhawulela kakhulu ukuhola kuma-polymer e-PVC ngale kwezinsuku zokugcina zika-2023. Lolu shintsho luye lwaphoqa izimboni—kusukela ekwakheni kuya kumadivayisi ezokwelapha—ukuba zishiye iziqinisi zensimbi esindayo zendabuko, ezibeka izingozi zokungcoliswa kwenhlabathi ngesikhathi sokulahlwa kanye nokukhishwa okunobuthi ngesikhathi sokushiswa.
Ngaphesheya kwe-Atlantic, ukuhlolwa kwengozi kwe-US EPA ka-2025 kuma-phthalates (ikakhulukazi i-Diisodecyl Phthalate, i-DIDP) kukhulise ukugxila ekuphepheni okungeziwe, ngisho nasezingxenyeni zokuzinzisa ezingaqondile. Ngenkathi ama-phthalates esebenza kakhulu njengezinto zokupholisa, ukuhlolwa kwawo kokulawula kudale umphumela ovunguzayo, okwenza abakhiqizi basebenzise amasu "okwakheka okuhlanzekile" ahlanganisa izinto zokupholisa ezingezona ezinobuthi. Lezi zinyathelo zokulawula azizona nje izithiyo zokuthobela imithetho - zishintsha amaketanga okuhlinzeka, kanti ama-50% emakethe yokuzinzisa i-PVC eqaphela imvelo manje ahlotshaniswa nezindlela ezingezona ezensimbi esindayo.
Izithambisi zeCalcium-Zinc Zithatha Isigaba Esiphakathi
Abaholayo ekuthatheni indawo yezakhiwo zensimbi esindayo yilabaiziqinisi ze-calcium-zinc (Ca-Zn). Njengoba inenani lika-$1.34 billion emhlabeni jikelele ngo-2024, le ngxenye kulindeleke ukuthi ikhule ku-CAGR engu-4.9%, ifinyelele ku-$1.89 billion ngo-2032. Ukukhanga kwayo kusesilinganisweni esingavamile: ukungabi nobuthi, ukuzinza okuhle kakhulu kokushisa, kanye nokuhambisana nezinhlelo zokusebenza ze-PVC ezahlukahlukene—kusukela kumaphrofayili efasitela kuya kumadivayisi ezokwelapha.
I-Asia-Pacific ibusa lokhu kukhula, ibangela u-45% wesidingo se-Ca-Zn emhlabeni wonke, okubangelwa ukukhiqizwa okukhulu kwe-PVC eShayina kanye nomkhakha wokwakha okhulayo eNdiya. EYurophu, okwamanje, intuthuko yezobuchwepheshe iveze izingxube ze-Ca-Zn ezisebenza kahle kakhulu ezihlangabezana nezindinganiso eziqinile ze-REACH ngenkathi zithuthukisa ukusebenza kahle kokucubungula. Lezi zindlela manje zisekela izinhlelo zokusebenza ezibalulekile njengokupakisha ukudla kanye nezintambo zikagesi, lapho ukuphepha nokuqina kungaxoxiswana khona.
Okuphawulekayo,Iziqinisi ze-Ca-Znnazo ziyavumelana nemigomo yezomnotho ojikelezayo. Ngokungafani nezinye izindlela ezisekelwe kumthofu, ezenza kube nzima ukuphinda kusetshenziswe i-PVC ngenxa yezingozi zokungcola, ukwakheka kwe-Ca-Zn kwesimanje kwenza kube lula ukuphinda kusetshenziswe ngomshini, okuvumela imikhiqizo ye-PVC yangemva komthengi ukuthi isetshenziswe kabusha ibe izinhlelo zokusebenza ezintsha ezihlala isikhathi eside njengamapayipi kanye nolwelwesi lokuphahla.
Ukuqamba Okusha Kokusebenza Nokusetshenziswa Kabusha
Ngaphandle kokukhathazeka ngobuthi, imboni igxile kakhulu ekuthuthukiseni ukusebenza kwe-stabilizer—ikakhulukazi ezinhlelweni ezidinga amandla amaningi. Izakhiwo ezisebenza kahle njenge-GY-TM-182 zibeka amazinga amasha, zinikeza ukucaca okuphezulu, ukumelana nesimo sezulu, kanye nokuqina kokushisa uma kuqhathaniswa neziqinisi ze-tin zendabuko. Lokhu kuthuthuka kubalulekile emikhiqizweni ye-PVC edinga ukucaca, njengefilimu zokuhlobisa namadivayisi ezokwelapha, lapho kokubili ubuhle nokuqina kubalulekile.
Izithambisi ze-tin, yize zibhekene nezingcindezi zemvelo, zigcina ubukhona obukhethekile emikhakheni ekhethekile. Njengoba zibiza u-$885 million ngo-2025, imakethe yezithambisi ze-tin ikhula ngokulinganisela (3.7% CAGR) ngenxa yokumelana nokushisa okungenakuqhathaniswa ezisetshenziswayo zezimoto nezimboni. Kodwa-ke, abakhiqizi manje sebebeka phambili izinhlobo ze-tin "eziluhlaza" ezinobuthi obuncishisiwe, okubonisa igunya elibanzi lokuqina kwemboni.
Umkhuba ofanayo ukuthuthukiswa kweziqinisi ezilungiselelwa ukuphinda zisetshenziswe. Njengoba izinhlelo zokuphinda zisetshenziswe ze-PVC ezifana ne-Vinyl 2010 kanye ne-Vinyloop® zikhula, kunesidingo esikhulayo sezithasiselo ezingawohloki phakathi kwemijikelezo eminingi yokuphinda zisetshenziswe. Lokhu kuholele ekusungulweni okusha kwe-chemistry yokuqinisa okugcina izakhiwo ze-PVC zemishini ngisho nangemva kokucutshungulwa okuphindaphindiwe—okuyisihluthulelo sokuvala umjikelezo kwezomnotho ojikelezayo.
Ukusungula Okusekelwe Ku-Bio kanye Nokuqhutshwa Yi-ESG
Ukuzinza akukhona nje ukuqeda ubuthi—kumayelana nokucabanga kabusha ngokuthola izinto zokusetshenziswa. Ama-Ca-Zn complexes asafufusa asekelwe ku-bio, atholakala ezitshalweni zokudla ezivuselelekayo, ayathola ukuthandwa, enikeza indawo ephansi yekhabhoni kunezinye izindlela ezisekelwe ku-petroleum. Nakuba kuseyingxenyana encane, lawa ma-bio-stabilizer ahambisana nemigomo ye-ESG yezinkampani, ikakhulukazi eYurophu naseNyakatho Melika, lapho abathengi kanye nabatshalizimali befuna khona ukucaca ezindleleni zokuhlinzeka.
Lokhu kugxila ekusimeni okuzinzile nakho kuguqula ukuguquguquka kwemakethe. Umkhakha wezokwelapha, isibonelo, manje ucacisa iziqinisi ezingezona ezinobuthi zamadivayisi okuxilonga kanye nokupakisha, okuqhuba ukukhula kwaminyaka yonke okungu-18% kule ndawo. Ngokufanayo, imboni yokwakha—ebangela ngaphezu kuka-60% wesidingo se-PVC—ibeka phambili iziqinisi ezithuthukisa ukuqina kanye nokusetshenziswa kabusha, zisekela izitifiketi zesakhiwo esiluhlaza.
Izinselele kanye Nomgwaqo Ongaphambili
Naphezu kwentuthuko, izinselelo ziyaqhubeka. Amanani entengo ye-zinc aguquguqukayo (ahlanganisa u-40-60% wezindleko zezinto zokusetshenziswa ze-Ca-Zn) adala ukungaqiniseki kochungechunge lokuhlinzekwa. Okwamanje, ukusetshenziswa kwezinga lokushisa eliphezulu kusahlola imikhawulo yeziqinisi ezinobungani nemvelo, okudinga i-R&D eqhubekayo ukuvala izikhala zokusebenza.
Kodwa-ke indlela icacile: Izithambisi ze-PVC ziyashintsha kusukela ezithambisweni ezisebenzayo kuya ezinika amandla amasu emikhiqizo ye-PVC eqhubekayo. Kubakhiqizi emikhakheni efana nama-blinds aseVenetian—lapho ukuqina, ubuhle, kanye neziqinisekiso zemvelo kuhlangana khona—ukwamukela lezi zithambisi zesizukulwane esilandelayo akuyona nje into edingekayo yokulawula kodwa kuyinzuzo yokuncintisana. Njengoba u-2025 uqhubeka, ikhono lemboni lokulinganisela ukusebenza, ukuphepha, kanye nokusetshenziswa kabusha lizochaza indima yalo ekucindezelweni komhlaba wonke kwezinto eziyindilinga.
