Njengoko ishishini le-PVC likhawuleza ukuya ekuzinzeni nasekusebenzeni kakuhle, iziqinisi ze-PVC—izongezo ezibalulekileyo ezithintela ukuwohloka kobushushu ngexesha lokucubungula kunye nokwandisa ubomi bemveliso—ziye zaba yindawo ephambili yokuhlaziya kunye nokuhlolwa kwemithetho. Ngo-2025, imixholo emithathu ephambili ilawula iingxoxo: utshintsho olukhawulezileyo oluya kwiifomyula ezingenabungozi, ukuqhubela phambili kwiiteknoloji ezihambelana nokuphinda zisetyenziswe, kunye nempembelelo ekhulayo yemithetho yokusingqongileyo yehlabathi. Nantsi ingqwalasela enzulu kwezona zinto ziphambili ziphuhlisayo.
Uxinzelelo Olulawulayo Lubangela Ukuphela Kwezinto Ezigcina Isinyithi Sinzima
Iintsuku ze-lead kunye ne-cadmium-basedIziqinisi zePVCzibalwa, njengoko imithetho engqongqo kwihlabathi liphela inyanzela abavelisi ukuba basebenzise ezinye iindlela ezikhuselekileyo. Umgaqo we-REACH we-EU ube ngowona ubalulekileyo kolu tshintsho, kunye nophononongo oluqhubekayo lwe-Annex XVII olumiselwe ukuthintela ngakumbi i-lead kwi-PVC polymers ngaphaya kwexesha elimiselweyo lika-2023. Olu tshintsho luye lwanyanzela amashishini—ukusuka ekwakheni ukuya kwizixhobo zonyango—ukuba ayeke izinto ezizinzisa isinyithi esinzima, ezibeka umngcipheko wongcoliseko lomhlaba ngexesha lokulahla kunye nokukhutshwa kwetyhefu ngexesha lokutshiswa.
Kuyo yonke iAtlantiki, uvavanyo lomngcipheko lwe-US EPA luka-2025 kwi-phthalates (ngokukodwa i-Diisodecyl Phthalate, i-DIDP) luye lwandisa ingqwalasela kukhuseleko lokongeza, nokuba kumacandelo okuqinisa ngokungangqalanga. Ngelixa ii-phthalates zisebenza njengeeplastiki, ukuphononongwa kwazo ngokwemithetho kudale isiphumo esibi, okubangela ukuba abavelisi bamkele amaqhinga "okucoca apheleleyo" aquka iziqinisi ezingezizo iityhefu. Ezi ntshukumo zokulawula azizizo nje izithintelo zokuthobela imithetho—ziphinda zibumbe imixokelelwane yokubonelela, apho ama-50% emarike yokuqinisa i-PVC eqaphela imeko-bume ngoku inxulunyaniswa nezinye iindlela zesinyithi esingenzima.
IziQinisekiso zeCalcium-Zinc Zithatha Inqanaba Eliphakathi
Abona bantu bakhokelayo ekuthatheni indawo yezixhobo zesinyithi esinzima zeziiziqinisi zekhompawundi ze-calcium-zinc (Ca-Zn). Eli candelo, elixabisa i-$1.34 yezigidigidi kwihlabathi liphela ngo-2024, kulindeleke ukuba likhule kwi-CAGR ye-4.9%, lifikelele kwi-$1.89 yezigidigidi ngo-2032. Ukutsala kwabo kuxhomekeke kwibhalansi engaqhelekanga: ukungabi natyhefu, uzinzo oluhle kakhulu lobushushu, kunye nokuhambelana nezicelo ezahlukeneyo ze-PVC—ukusuka kwiiprofayili zefestile ukuya kwizixhobo zonyango.
I-Asia-Pacific ilawula olu hlumo, ibangela i-45% yemfuno yehlabathi ye-Ca-Zn, eqhutywa yimveliso enkulu ye-PVC yaseTshayina kunye necandelo lokwakha elikhulayo eIndiya. Okwangoku, eYurophu, uphuhliso lwetekhnoloji luvelise imixube ye-Ca-Zn esebenza kakuhle ehlangabezana nemigangatho engqongqo ye-REACH ngelixa iphucula ukusebenza kakuhle kokucubungula. Ezi fomyula ngoku zixhasa usetyenziso olubalulekileyo olufana nokupakisha ukutya kunye neentambo zombane, apho ukhuseleko kunye nokuqina kungaxoxiswana.
Okuphawulekayo kukuba,Iziqinisi zeCa-Znzikwahambelana neenjongo zoqoqosho olujikelezayo. Ngokungafaniyo nezinye iindlela ezisekelwe kwilothe, ezenza kube nzima ukuphinda kusetyenziswe i-PVC ngenxa yemingcipheko yongcoliseko, iindlela zanamhlanje ze-Ca-Zn zenza kube lula ukuphinda kusetyenziswe ngoomatshini, nto leyo evumela ukuba iimveliso ze-PVC ezisetyenziswa emva komthengi zisetyenziswe kwakhona zibe zizicelo ezintsha ezihlala ixesha elide ezifana nemibhobho kunye nee-membrane zophahla.
Utshintsho kwiNtsebenzo kunye nokuSebenza kwakhona
Ngaphandle kweengxaki zobungozi, eli shishini ligxile kakhulu ekuphuculeni ukusebenza kwe-stabilizer—ingakumbi kwizicelo ezifuna umgudu omkhulu. Iifomyula ezisebenzayo ezifana ne-GY-TM-182 zibeka imilinganiselo emitsha, zibonelela ngokucaca okuphezulu, ukumelana nemozulu, kunye nozinzo lobushushu xa kuthelekiswa neziqinisi ze-organic tin zemveli. Olu phuculo lubalulekile kwiimveliso ze-PVC ezifuna ukucaca, ezifana neefilimu zokuhombisa kunye nezixhobo zonyango, apho ubuhle kunye nokuqina kubalulekile.
Izithambisi zetin, nangona zijongene noxinzelelo lokusingqongileyo, zigcina ubukho obukhethekileyo kumacandelo akhethekileyo. Zixabisa i-$885 yezigidi ngo-2025, imakethi yezithambisi zetin ikhula ngokuphakathi (3.7% CAGR) ngenxa yokumelana nobushushu obungenakuthelekiswa nanto kwizicelo zeemoto nakwimizi-mveliso. Nangona kunjalo, abavelisi ngoku babeka phambili iintlobo zetin "eziluhlaza" ezinobuthi obuncitshisiweyo, nto leyo ebonisa igunya elibanzi lozinzo lweshishini.
Enye indlela efanayo kukuphuhliswa kweziqinisi ezilungele ukusetyenziswa kwakhona. Njengoko iinkqubo zokuphinda usebenzise i-PVC ezifana neVinyl 2010 kunye neVinyloop® zisanda, kukho imfuno ekhulayo yezongezo ezingonakalisiyo ngexesha lemijikelo emininzi yokuphinda usebenzise. Oku kukhokelele kwiindlela ezintsha kwikhemistri yokuqinisa ezigcina iipropati zoomatshini zePVC nasemva kokulungiswa ngokuphindaphindiweyo—isitshixo sokuvala loo mjikelo kwiindlela ezijikelezayo.
Izinto ezintsha ezisekelwe kwi-Bio kunye ne-ESG
Uzinzo alupheleli nje ekupheliseni iityhefu—lumalunga nokucinga ngokutsha ngokufunyanwa kwezinto eziluhlaza. Ii-Ca-Zn complexes ezisakhulayo ezisekelwe kwi-bio, ezisuka kwi-feedstocks ezivuselelekayo, ziya zithandwa, zibonelela nge-carbon footprint ephantsi kunezinye iindlela ezisekelwe kwi-petroleum. Nangona ziseyicandelo elincinci, ezi bio-stabilizers zihambelana neenjongo ze-ESG zeenkampani, ngakumbi eYurophu naseMntla Melika, apho abathengi kunye nabatyali-mali bafuna ngakumbi ukucaca kwiindlela zokubonelela.
Olu gxininiso ekuzinzeni lukwaguqula indlela ezisebenza ngayo iimarike. Icandelo lezonyango, umzekelo, ngoku lichaza izinto ezizinzisa izinto ezingenabungozi kwizixhobo zokuxilonga kunye nokupakisha, nto leyo eqhuba ukukhula konyaka kwe-18% kule ndawo. Ngokufanayo, ishishini lokwakha—elibangela ngaphezulu kwe-60% yemfuno ye-PVC—libeka phambili izinto ezizinzisa izinto eziphucula ukuqina kunye nokuphinda zisetyenziswe, zixhasa iziqinisekiso zezakhiwo eziluhlaza.
Imingeni kunye nendlela engaphambili
Nangona kukho inkqubela phambili, imingeni isaqhubeka. Amaxabiso eemveliso ze-zinc aguquguqukayo (aquka i-40-60% yeendleko zezinto ezikrwada ze-Ca-Zn) adala ukungaqiniseki kwekhonkco lokubonelela. Okwangoku, usetyenziso lobushushu obuphezulu lusavavanya imida yezibambisi ezinobuhlobo nokusingqongileyo, zifuna i-R&D eqhubekayo ukuvala izikhewu zokusebenza.
Sekunjalo indlela elandelwayo icacile: Iziqinisi zePVC ziyatshintsha ukusuka kwizinto eziluncedo ukuya kwizinto ezinika amandla iimveliso zePVC ezizinzileyo. Kubavelisi abakwicandelo elifana neefestile zaseVenetian—apho ukuqina, ubuhle, kunye neziqinisekiso zokusingqongileyo kudibana khona—ukwamkela ezi ziqinisi zesizukulwana esilandelayo akuyomfuneko nje yokulawula kodwa kunenzuzo yokukhuphisana. Njengoko u-2025 uqhubeka, amandla oshishino okulinganisela ukusebenza, ukhuseleko, kunye nokuphinda kusetyenziswe izinto kuya kuchaza indima yalo ekutyhaleleni izinto ezijikelezayo kwihlabathi liphela.
