Izembozo ezithwala amanzi: Ukugeleza okuqhubekayo kwentuthuko

Sinjani isimo emakethe yezimbozo ezithwala amanzi?

Izibikezelo zemakethe zihlala zinhle njengoba kungalindelwa emkhakheni oqiniswa ukuhambisana kwawo nemvelo. Kodwa iziqinisekiso zemvelo aziyona into ebaluleke kakhulu, kanti izindleko kanye nokulula kokusetshenziswa kusabalulekile.

Izinkampani zocwaningo ziyavumelana ngokukhula okuqhubekayo kwemakethe yomhlaba wonke yezingubo ezithwala amanzi. I-Vantage Market Research ibika inani lama-euro ayizigidigidi ezingama-90.6 emakethe yomhlaba wonke ngo-2021 futhi ibikezela ukuthi izofinyelela inani lama-euro ayizigidigidi eziyi-110 ngo-2028, ku-CAGR engu-3.3% esikhathini esibikezelwe.

I-Markets and Markets inikeza inani elifanayo lomkhakha othwala amanzi ngo-2021, ku-EUR 91.5 billion, nge-CAGR enethemba kakhulu engu-3.8% kusukela ngo-2022 kuya ku-2027 ukuze ifinyelele ku-EUR 114.7 billion. Le nkampani ilindele ukuthi imakethe ifinyelele ku-EUR 129.8 billion ngo-2030 kanye ne-CAGR ekhuphukela ku-4.2% kusukela ngo-2028 kuya ku-2030.

Idatha ye-IRL isekela lo mbono, nge-CAGR iyonke engu-4% emakethe ethwala amanzi, kulokhu esikhathini esisukela ku-2021 kuya ku-2026. Amanani ezigaba ngazinye anikezwe ngezansi futhi anikeza ukuqonda okukhulu.

Ububanzi besabelo esikhulu semakethe

Izembozo zokwakha zibusa ukuthengiswa okuphelele komhlaba wonke kanye nomthamo obala ngaphezu kwama-80% wesabelo semakethe ngokusho kwe-IRL, ebike inani lamathani ayizigidi ezingama-27.5 kulesi sigaba somkhiqizo ngo-2021. Lokhu kulindeleke ukuthi kufinyelele cishe amathani ayizigidi ezingama-33.2 ngo-2026, kukhule kancane kancane ku-CAGR engu-3.8%. Lokhu kukhula kungenxa yesidingo esikhulu ngenxa yemisebenzi yokwakha kunokuba kube ushintsho olukhulu kwezinye izinhlobo zezembozo njengoba lokhu kuyindlela yokusebenza lapho izembozo ezithwala amanzi sezivele zinesisekelo esiqinile.

Izimoto zimelela ingxenye yesibili ngobukhulu ngokukhula kwaminyaka yonke okungu-3.6%. Lokhu kusekelwa kakhulu ukwanda kokukhiqizwa kwezimoto e-Asia, ikakhulukazi eShayina naseNdiya, ngenxa yesidingo sabathengi.

Izicelo ezithakazelisayo ezinendawo yokubeka izinto ezithwala amanzi ukuze zithole isabelo esikhulu eminyakeni embalwa ezayo zifaka phakathi ukubekwa kwezinkuni zezimboni. Intuthuko yezobuchwepheshe izosiza ekukhuphukeni okunempilo kwesabelo semakethe esingaphansi kuka-5% kulo mkhakha - kusuka ku-26.1% ngo-2021 kuya ku-30.9% obikezelwe ngo-2026 ngokusho kwe-IRL. Ngenkathi izicelo zasolwandle zimelela umkhakha omncane kakhulu wokufaka izicelo obekwe ku-0.2% wemakethe iyonke ethwala amanzi, lokhu kusamelela ukukhuphuka kwamathani angu-21,000 eminyakeni emi-5, ku-CAGR engu-8.3%.

Abashayeli besifunda

Cishe u-22% wazo zonke izimbozo eYurophu ezithwala amanzi [Akkeman, 2021]. Kodwa-ke, esifundeni lapho ucwaningo nentuthuko kuqhutshwa khona yimithethonqubo yokwehlisa ama-VOC, njengoba kunjalo naseNyakatho Melika, izimbozo ezithwala amanzi ezithatha indawo yalezo eziqukethe izinyibilikisi sezibe yindawo yokucwaninga. Izicelo zezimoto, zokuvikela kanye nezimbozo zokhuni ziyizindawo eziyinhloko zokukhula.

E-Asia-Pacific, ikakhulukazi eShayina naseNdiya, abashayeli abakhulu bemakethe bahlobene nomsebenzi wokwakha osheshayo, ukufuduka kwabantu emadolobheni kanye nokwanda kokukhiqizwa kwezimoto futhi kuzoqhubeka nokuhola isidingo. Kusekhona ithuba elikhulu le-Asia-Pacific ngale kwezakhiwo nezimoto, isibonelo, ngenxa yokwanda kwesidingo sefenisha yokhuni kanye nezinto zikagesi ezizuza kakhulu ekumbozweni okusekelwe emanzini.

Emhlabeni wonke, ukucindezeleka okuqhubekayo kwesidingo sezimboni kanye nabathengi sokuzinza okukhulu kuqinisekisa ukuthi umkhakha othwala amanzi uhlala ugxile kakhulu ekusunguleni izinto ezintsha kanye nokutshalwa kwezimali.

Ukusetshenziswa kabanzi kwama-resin e-acrylic

Ama-resin e-Acrylic ayiklasi elikhula ngokushesha lama-resin okumboza asetshenziswa ezinhlobonhlobo zezicelo zawo zamakhemikhali nezomshini kanye nezakhiwo zobuhle. Ama-resin e-acrylic athwala amanzi athola amaphuzu aphezulu ekuhlolweni komjikelezo wokuphila futhi abona isidingo esikhulu kakhulu ezinhlelweni zezicelo zezimoto, izakhiwo kanye nezokwakha. I-Vantage ibikezela ukuthi ikhemistri ye-acrylic izobala ngaphezu kwe-15% yokuthengiswa okuphelele ngo-2028.

Ama-resin e-epoxy athwala amanzi kanye ne-polyurethane coating nawo amelela izingxenye ezikhula kakhulu.

Izinzuzo ezinkulu emkhakheni othwala amanzi yize kusenezinselelo ezinkulu

Intuthuko eluhlaza neqhubekayo ngokwemvelo igxila ekugqokeni okuthwalwa ngamanzi ukuze kuhambisane kakhulu nemvelo uma kuqhathaniswa nezinye izindlela ezithwalwa yi-solvent. Njengoba kunezakhi eziphilayo eziguquguqukayo noma ezingcolisayo zomoya ezincane noma ezingenazo, imithethonqubo eqinile ikhuthaza ukusetshenziswa kwamakhemikhali athwalwa ngamanzi njengendlela yokunciphisa ukukhishwa kwegesi nokusabela esidingweni semikhiqizo enobungani nemvelo. Izinto ezintsha zobuchwepheshe zifuna ukwenza kube lula ukwamukela ubuchwepheshe obuthwalwa ngamanzi ezigabeni zemakethe ezingafuni ukushintsha ngenxa yezindleko kanye nokukhathazeka kokusebenza.

Akukho ukubalekela izindleko eziphakeme ezihilelekile ezinhlelweni ezithwala amanzi, kungakhathaliseki ukuthi lokho kuhlobene nokutshalwa kwezimali ku-R&D, imigqa yokukhiqiza noma ukusetshenziswa kwangempela, okuvame ukudinga izinga eliphezulu lobuchwepheshe. Ukwenyuka kwamanani kwakamuva ezintweni zokusetshenziswa, ukuhlinzekwa kanye nokusebenza kwenza lokhu kube yinto ebalulekile.

Ngaphezu kwalokho, ukuba khona kwamanzi ezimbozweni kudala inkinga ezimweni lapho umswakama kanye nokushisa okuhlobene kuthinta ukoma. Lokhu kuthinta ukwamukelwa kobuchwepheshe obuthwalwa ngamanzi ukuze kusetshenziswe ezimbonini ezifundeni ezifana neMpumalanga Ephakathi kanye ne-Asia-Pacific ngaphandle kokuthi izimo zingalawulwa kalula - njengoba kungenzeka ngezinhlelo zokusebenza zezimoto ezisebenzisa ukupholisa okuphezulu.

Ukulandela imali

Ukutshalwa kwezimali kwakamuva kwabadlali abakhulu kusekela ukuthambekela kwemakethe okubikezelwe:

• I-PPG itshale imali engaphezu kwezigidi eziyi-9 zama-euro ukuze yandise umkhiqizo wayo waseYurophu wezingubo ze-OEM zezimoto ukuze ikhiqize ama-basecoat athwala amanzi.
• EShayina, i-Akzo Nobel itshale imali emugqeni omusha wokukhiqiza izembozo ezithwala amanzi. Lokhu kukhulisa umthamo ngokuhambisana nesidingo esikhulayo esilindelekile sopende oluphansi lwe-VOC, olusekelwe emanzini ezweni. Abanye abadlali bemakethe abasebenzisa amathuba akulesi sifunda bahlanganisa i-Axalta, eyakha isitshalo esisha ukuhlinzeka ngemakethe yezimoto echumayo yaseShayina.

Ithiphu lomcimbi

Izinhlelo ezisekelwe emanzini nazo zigxile kwi-EC Conference Bio-based kanye ne-Water-based Coatings ngoNovemba 14 no-15 eBerlin, eJalimane.Engqungqutheleni uzofunda ngentuthuko yakamuva ekumbozweni okusekelwe ku-bio kanye nokusekelwe emanzini.
