Izindwangu ezithwala amanzi: Intuthuko eqhubekayo

Sinjani isimo emakethe ye-coatings ehamba ngamanzi?

Izibikezelo zemakethe zihle ngokungaguquki njengoba kungalindeleka emkhakheni oqiniswe ukuhambisana kwawo kwemvelo. Kodwa imininingwane ye-eco ayiyona yonke into, ngezindleko nokusebenziseka kalula kusacatshangelwa ezibalulekile.

Izinkampani zocwaningo ziyavumelana ngokukhula okuqhubekayo kwemakethe yezingubo ezithwala amanzi emhlabeni jikelele. I-Vantage Market Research ibika inani lama-EUR 90.6 billion emakethe yomhlaba wonke ngo-2021 futhi iphrojekthi izofinyelela inani lama-EUR 110 billion ngo-2028, ku-CAGR ka-3.3 % esikhathini sokubikezela.

Izimakethe Nezimakethe zinikeza inani elifanayo lomkhakha othwala amanzi ngo-2021, kuma-EUR ayizigidi eziyizinkulungwane ezingama-91.5, nge-CAGR enethemba elikhulu lika-3.8 % ukusuka ngo-2022 kuya ku-2027 ukuze ifinyelele ku-EUR 114.7 billion. Inkampani ilindele ukuthi imakethe ifinyelele ku-EUR 129.8 billion ngo-2030 kanti i-CAGR ikhuphukela ku-4.2 % ukusuka ngo-2028 kuya ku-2030.

Idatha ye-IRL isekela lo mbono, nge-CAGR isiyonke engu-4 % yemakethe ethwala amanzi, kulokhu isikhathi sika-2021 kuya ku-2026. Amanani ezigaba ngazinye anikezwe ngezansi futhi anikeza ukuqonda okukhulu.

Ububanzi besabelo semakethe esikhulu

Izembatho zezakhiwo zibusa inani eliphelele lokuthengiswa komhlaba wonke nokubalwa kwevolumu engaphezu kuka-80 % wesabelo semakethe ngokusho kwe-IRL, eyabika umthamo wamathani ayizigidi ezingu-27.5 kulesi sigaba somkhiqizo ngo-2021. Lokhu kulindeleke ukuthi kufinyelele cishe kumathani ayizigidi ezingu-33.2 ngo-2026, kancane kancane. ikhula ku-CAGR ka-3.8%. Lokhu kukhula ngokuyinhloko kubangelwa ukwanda kwesidingo ngenxa yemisebenzi yokwakha esikhundleni sokushintshwa okukhulu okuvela kwezinye izinhlobo zokumboza uma kubhekwa ukuthi lokhu kuwuhlelo lapho izimbotshana ezithwala amanzi sezivele zinendawo eqinile.

Owezimoto umele ingxenye yesibili ngobukhulu ngokukhula okuhlanganisiwe konyaka ngo-3.6%. Lokhu kusekelwa ngokwezinga elikhulu ngokwanda kokukhiqizwa kwezimoto e-Asia, ikakhulukazi i-China ne-India, ukuphendula isidingo sabathengi.

Izinhlelo zokusebenza ezithokozisayo ezinobubanzi bezinto zokumboza ezithwala amanzi ukuze zithwebule isabelo esikhulu eminyakeni embalwa ezayo zifaka okokumbozwa ngokhuni lwezimboni. Intuthuko yezobuchwepheshe izosiza ukwenyuka okunempilo kwesabelo semakethe esingaphansi kuka-5 % kulo mkhakha - sisuka ku-26.1 % ngo-2021 siye ku-30.9 % ebikezelwe ngo-2026 ngokusho kwe-IRL. Yize izicelo zasolwandle zimele umkhakha wezicelo omncane kunayo yonke oshadiwe ku-0.2 % wesamba semakethe etholakala emanzini, lokhu kusamele ukukhuphuka kwamathani angama-21,000 metric eminyakeni emi-5, ku-CAGR ka-8.3%.

Abashayeli bezifunda

Cishe amaphesenti angama-22 kuphela awo wonke ama-coatings eYurophu aphuma emanzini [Akkeman, 2021]. Kodwa-ke, endaweni lapho ucwaningo nentuthuko iqhutshwa khona yimithethonqubo yokwehlisa ama-VOC, njengoba kwenzeka futhi eNyakatho Melika, izimbotshana ezithwala amanzi ezithatha indawo yalezo eziqukethe izincibilikisi seziphenduke isizinda socwaningo. Izicelo zezimoto, zokuzivikela nezokhuni ziyizindawo zokukhula eziyinhloko

E-Asia-Pacific, ikakhulukazi e-China nase-India, abashayeli bemakethe ababalulekile bahlobene nomsebenzi wokwakha osheshayo, ukuthuthela emadolobheni kanye nokwanda kokukhiqizwa kwezimoto futhi bazoqhubeka nokuhola isidingo. Kusene-scope enkulu ye-Asia-Pacific ngale kwezakhiwo nezimoto, isibonelo, ngenxa yesidingo esikhulayo sefenisha yokhuni nezinto zikagesi ezihlomula ngokwandayo ngokumbozwa ngamanzi.

Embulungeni yonke, ingcindezi eqhubekayo embonini kanye nesidingo sabathengi sokusimama okukhulu siqinisekisa ukuthi umkhakha ophethwe ngamanzi uhlala ugxile ekugxileni ekusungulweni nasekutshalweni kwezimali.

Ukusetshenziswa okubanzi kwama-resin acrylic

Izinhlayiya ze-Acrylic ziyikilasi elikhula ngokushesha lezinhlayiya zokuhlanganisa ezisetshenziswa ezinhlobonhlobo zezicelo zezici zabo zamakhemikhali nezomshini kanye nezakhiwo zobuhle. Ama-acrylic athwala amanzi athola amaphuzu aphezulu ekuhlolweni komjikelezo wempilo futhi abone isidingo esiqine kakhulu kumasistimu wezinhlelo zokusebenza zezimoto, zezakhiwo nezokwakha. I-Vantage ibikezela ukuthi i-acrylic chemistry izobalelwa ngaphezu kwe-15% yokuthengiswa okuphelele ngo-2028.

Ama-resin e-epoxy aphethwe ngamanzi kanye ne-polyurethane nawo amele izingxenye zokukhula okuphezulu.

Izinzuzo ezinkulu emkhakheni ohamba ngamanzi nakuba izinselelo eziyinhloko zisekhona

Ukuthuthuka okuluhlaza nokusimeme ngokwemvelo kubeka ukugxila ezingxenyeni ezithwala amanzi ngokuhambisana kwazo okukhulu kwemvelo uma kuqhathaniswa nezinye izinto ezithwala i-solvent. Njengoba kunezinhlanganisela zezinto eziphilayo ezingaguquki noma ezingaguquki noma izinto ezingcolisa umoya, imithetho eqhubeka iqina kakhulu ikhuthaza ukusetshenziswa kwezindawo zamakhemikhali ezithwala amanzi njengendlela yokunciphisa ukungcola kanye nokusabela esidingweni semikhiqizo evumelana nemvelo eyengeziwe. Izindlela ezintsha zobuchwepheshe zifuna ukwenza kube lula ukusebenzisa ubuchwepheshe obuthwala amanzi ezigabeni zemakethe ezinqena kakhulu ukushintsha ngenxa yezindleko nokusebenza kokukhathazeka.

Akukho ukubalekela izindleko eziphakeme ezihilelekile ezinhlelweni ezithwala amanzi, noma ngabe lokho kuhlobene nokutshalwa kwezimali ku-R&D, imigqa yokukhiqiza noma isicelo sangempela, esivame ukudinga izinga eliphezulu lobuchwepheshe. Izintengo zakamuva zikhuphuka ezintweni ezingavuthiwe, ukuhlinzekwa kanye nokusebenza kwenza lokhu kucatshangelwe okubalulekile.

Ngaphezu kwalokho, ukuba khona kwamanzi ezimbotsheni kubangela inkinga ezimweni lapho umswakama ohlobene nokushisa kuthinta ukomisa. Lokhu kunomthelela ekwamukelweni kobuchwepheshe obuthwala amanzi ezimbonini ezisebenza ezindaweni ezifana neMpumalanga Ephakathi ne-Asia-Pacific ngaphandle uma izimo zingalawuleka kalula - njengoba kungenzeka ngezinhlelo zezimoto ezisebenzisa ukwelapha izinga lokushisa eliphezulu.

Ukulandela imali

Ukutshalwa kwezimali kwakamuva kwabadlali abakhulu kusekela amathrendi emakethe abikezelwe:

• I-PPG itshale imali engaphezu kwezigidi ezingu-EUR ukuze yandise ukukhiqizwa kwayo kwase-Europe kwezingubo ze-OEM zezimoto ukuze kukhiqizwe ama-basecoat athwala amanzi.
• E-China, u-Akzo Nobel utshale imali emgqeni omusha wokukhiqiza wezingubo ezithwala amanzi. Lokhu kukhulisa umthamo ngokuhambisana nesidingo esikhulayo esilindelekile se-VOC ephansi, opende abasekelwe emanzini bezwe. Abanye abadlali bemakethe abasebenzisa amathuba kulesi sifunda bahlanganisa i-Axalta, eyakha imboni entsha yokuhlinzeka ngemakethe yezimoto echumayo yaseChina.

Ithiphu yomcimbi

Amasistimu asekelwe emanzini nawo agxile ku-EC Conference Bio-based and Water-based Coatings ngoNovemba 14 no-15 eBerlin, eJalimane.. Engqungqutheleni uzofunda mayelana nentuthuko yakamuva ye-bio-based kanye ne-water-based coatings.
