Eminyakeni yamuva nje, kuye kwaba nokugxila okwandayo ekuzinzeni nasekuzibophezeleni kwemvelo, okuholela ekudingeni okuphezulu kwezingubo ezisekelwe emanzini. Lo mkhuba usekelwa futhi izinhlelo zokulawula ezihloselwe ukunciphisa ukukhishwa kwe-VOC kanye nokukhuthaza ezinye izindlela ezilungele imvelo.
Imakethe yokumboza amanzi kulindeleke ukuthi ikhule isuka ku-EUR 92.0 billion ngo-2022 iye ku-EUR 125.0 billion ngo-2030, okukhombisa izinga lokukhula lonyaka lika-3.9%. Imboni yokumboza esekelwe emanzini iyaqhubeka nokusungula izinto ezintsha, ithuthukisa ukwakheka nobuchwepheshe obusha ukuze kuthuthukiswe ukusebenza, ukuqina, nokusebenza kahle kwesicelo. Njengoba ukusimama kuzuza ukubaluleka kokuthandwa ngabathengi kanye nezidingo zokulawula, imakethe yezingubo ezisekelwe emanzini kulindeleke ukuthi iqhubeke nokukhula.
Ezimakethe ezisafufusa zesifunda sase-Asia-Pacific (APAC), kunesidingo esikhulu sezingubo ezisekelwe emanzini ngenxa yezigaba ezihlukene zokuthuthuka komnotho kanye nohlu olubanzi lwezimboni. Ukukhula komnotho kuqhutshwa ngokuyinhloko amazinga okukhula aphezulu kanye nokutshalwa kwezimali okubalulekile ezimbonini ezifana nezezimoto, izimpahla zabathengi nezinto zikagesi, ezokwakha, nefenisha. Lesi sifunda singesinye sezindawo ezikhula ngokushesha kukho kokubili ukukhiqizwa kanye nesidingo samapende aphuma emanzini. Ukukhethwa kobuchwepheshe be-polymer kungahluka ngokuya ngesigaba semakethe sokusetshenziswa kokuphela futhi, ngokwezinga elithile, izwe lokusetshenziswa. Kodwa-ke, kusobala ukuthi isifunda sase-Asia-Pacific siyashintsha kancane kancane sisuka embotsheni yendabuko esekwe kuncibilikisiwe siye kweziqinile, ezisekelwe emanzini, ezimbozwe ngempushana, nezinhlelo ezilapheka ngamandla.
Izakhiwo ezisimeme kanye nesidingo esikhulayo ezimakethe ezintsha kudala amathuba
Izakhiwo ezilungele imvelo, ukuqina, nobuhle obuthuthukisiwe kuthuthukisa ukusetshenziswa kuzo zonke izinhlelo zokusebenza. Imisebenzi emisha yokwakha, ukupenda kabusha, kanye nokutshalwa kwezimali okukhulayo ezimakethe ezisafufusa yizinto ezibalulekile ezihlinzeka ngamathuba okukhula kwabahlanganyeli bemakethe. Nokho, ukwethulwa kobuchwepheshe obusha kanye nokuntengantenga kwamanani entengo ye-titanium dioxide kuletha izinselele ezinkulu.
I-Acrylic resin coatings (AR) iphakathi kwezingubo ezisetshenziswa kakhulu endaweni yanamuhla. Lezi zinhlobonhlobo ziyizinto ezinengxenye eyodwa, ikakhulukazi ama-polymer e-acrylic akhiwe kusengaphambili ancibilika kuzincibilikisi ukuze asetshenziswe phezulu. Izinhlayiya ze-acrylic ezisekelwe emanzini zinikeza ezinye izindlela ezivumelana nemvelo, ukunciphisa iphunga nokusetshenziswa kwe-solvent ngesikhathi sokudweba. Nakuba ama-binder asekelwe emanzini evame ukusetshenziswa emihlobiso yokuhlobisa, abakhiqizi baphinde bahlakulela i-emulsion yamanzi kanye ne-dispersion resins ngokuyinhloko ehloselwe izimboni ezifana ne-electronics yabathengi, izimoto, nemishini yokwakha. I-Acrylic iyinhlaka esetshenziswa kakhulu ngenxa yamandla ayo, ukuqina, ukumelana ne-solvent enhle kakhulu, ukuguquguquka, ukumelana nomthelela, nobulukhuni. Ithuthukisa izindawo ezingaphezulu njengokubukeka, ukunamathela, nokumanzisa futhi inikeza ukugqwala nokumelana nokuklwebheka. Izinhlayiya ze-Acrylic zisebenzise ukuhlanganiswa kwazo kwe-monomer ukuze zikhiqize izibophezelo ze-acrylic ezitholakala emanzini ezifanele kokubili ukusetshenziswa kwangaphakathi nangaphandle. Lezi zibophezelo zisekelwe kubuchwepheshe obuhlukahlukene, okuhlanganisa ama-polymers ahlakazekayo, ama-polymers esixazululo, nama-polymer angemuva kwe-emulsified.
Ama-Acrylic Resins Aguquka Ngokushesha
Ngokukhula kwemithetho neziqondiso zemvelo, inhlaka ye-acrylic esekwe emanzini isiwumkhiqizo othuthukayo osebenza ngokuvuthwa kuzo zonke izimbotshana ezisekelwe emanzini ngenxa yokusebenza kwayo okuhle kakhulu. Ukuthuthukisa izakhiwo ezijwayelekile ze-acrylic resin nokwandisa ububanzi bokusebenza kwayo, izindlela ezihlukahlukene ze-polymerization nezindlela ezithuthukisiwe zokuguqulwa kwe-acrylate zisetshenziswa. Lezi zinguquko zihlose ukubhekana nezinselele ezithile, zikhuthaze ukukhula kwemikhiqizo ye-acrylic resin etholakala emanzini, futhi inikeze izakhiwo eziphakeme. Ukuqhubekela phambili, kuzoba nesidingo esiqhubekayo sokuqhubeka nokuthuthukisa i-acrylic resin esekwe emanzini ukuze kuzuzwe ukusebenza okuphezulu, ukusebenza okuningi, kanye nezici ze-eco-friendly.
Imakethe yezingubo zokugqoka esifundeni sase-Asia-Pacific ikhula kakhulu futhi kulindeleke ukuthi iqhubeke nokukhula ngenxa yokukhula kwezindawo zokuhlala, okungezona ezokuhlala kanye nezimboni. Isifunda sase-Asia-Pacific sihlanganisa izinhlobonhlobo zezomnotho ezigabeni ezihlukene zokuthuthukiswa komnotho kanye nezimboni eziningi. Lokhu kukhula kuqhutshwa ngokuyinhloko izinga lokukhula komnotho eliphezulu. Abadlali abaphambili abaphambili bandisa ukukhiqizwa kwabo kwezingubo ezisekelwe emanzini e-Asia, ikakhulukazi e-China nase-India.
Shift in Production uye emazweni ase-Asia
Isibonelo, izinkampani zomhlaba wonke zishintshela ukukhiqiza emazweni ase-Asia ngenxa yesidingo esikhulu nezindleko zokukhiqiza eziphansi, okunomthelela omuhle ekukhuleni kwezimakethe. Abakhiqizi abahamba phambili balawula ingxenye enkulu yemakethe yomhlaba. Imikhiqizo yamazwe ngamazwe efana ne-BASF, i-Axalta, ne-Akzo Nobel njengamanje ibambe iqhaza elikhulu emakethe yaseShayina yokumboza emanzini. Ngaphezu kwalokho, lezi zinkampani ezivelele zomhlaba zandisa ngenkuthalo amandla azo okunamathela emanzini e-China ukuze zithuthukise ukuncintisana kwazo. NgoJuni 2022, u-Akzo Nobel watshala imali emgqeni omusha wokukhiqiza eChina ukuze kwandiswe umthamo wokuletha imikhiqizo esimeme. Imboni yokumboza e-China kulindeleke ukuthi inwebe ngenxa yokugxila okwengeziwe emikhiqizweni ye-VOC ephansi, ukonga amandla, kanye nokuncipha kwe-emission.
Uhulumeni waseNdiya wethule uhlelo lwe-"Make in India" lokukhuthaza ukukhula kwemboni yakhe. Lolu hlelo lugxile emikhakheni engama-25, okuhlanganisa eyezimoto, indawo yezindiza, izitimela, amakhemikhali, ezokuvikela, ezokukhiqiza kanye nokupakisha. Ukukhula embonini yezimoto kusekelwa ukukhula kwamadolobha ngokushesha nezimboni, ukwanda kwamandla okuthenga, kanye nezindleko eziphansi zezisebenzi. Ukwandiswa kwabakhiqizi bezimoto abakhulu kuleli kanye nokwanda kwemisebenzi yokwakha, okuhlanganisa nemiklamo eminingana edinga imali enkulu, kuholele ekukhuleni komnotho ngokushesha eminyakeni yamuva. Uhulumeni utshala imali kumaphrojekthi engqalasizinda ngokusebenzisa utshalomali oluqondile lwangaphandle (i-FDI), okulindeleke ukuthi lwandise imboni kapende etholakala emanzini.
Imakethe iyaqhubeka nokubona isidingo esinamandla sezingubo ezihambisana nemvelo ezisuselwe ezintweni ezingavuthiwe zemvelo. Izembatho ezitholakala emanzini zithola ukuthandwa ngenxa yokugxila okukhulayo kokusimama kanye nemithetho eqinile ye-VOC. Ukwethulwa kwemithetho emisha nemithetho eqinile, okuhlanganisa nezinhlelo ezifana ne-European Commission's Eco-product Certification Scheme (ECS) nezinye izinhlaka zikahulumeni, kugcizelela ukuzibophezela ekuthuthukiseni indawo eluhlaza nesimeme enokukhishwa okuncane noma okungenabungozi kwe-VOC. Imithetho kahulumeni e-United States naseNtshonalanga Yurophu, ikakhulukazi leyo eqondise ukungcoliswa komoya, kulindeleke ukuthi iqhubekisele phambili ukwamukelwa kobuchwepheshe obusha, obunomoya omncane wokumboza. Ukuphendula le mikhuba, ukumbozwa kwamanzi kuye kwavela njengezixazululo ezingenamthofu ne-VOC, ikakhulukazi emnothweni ovuthiwe njengeNtshonalanga Yurophu kanye ne-US.
Kudingeka Intuthuko Ebalulekile
Ukuqwashisa okwandayo ngezinzuzo zalawa kapende olungele imvelo kuqhuba isidingo emikhakheni yezokwakha zezimboni, zokuhlala, nezokungahlali. Isidingo sokusebenza okuthuthukisiwe nokuqina ezimbotsheni eziphuma emanzini siqhubekisela phambili ukuthuthukiswa kwe-resin kanye nobuchwepheshe bokwengeza. Izembatho eziphuma emanzini zivikela futhi zithuthukise i-substrate, zibe nesandla emigomweni yokusimama ngokunciphisa ukusetshenziswa kwempahla eluhlaza kuyilapho kugcinwa i-substrate futhi kwakha ama-coatings amasha. Nakuba ukumbozwa kwamanzi kusetshenziswa kabanzi, kusenezinkinga zobuchwepheshe okufanele zixazululwe, njengokuthuthukisa ukuqina.
Imakethe ye-coatings yamanzi isalokhu inokuncintisana kakhulu, inamandla amaningana, izinselele, namathuba. Amafilimu asekelwe emanzini, ngenxa yemvelo ye-hydrophilic yama-resin nama-disperants asetshenzisiwe, alwela ukwakha imigoqo eqinile futhi axoshe amanzi. Izithasiselo, ama-surfactants, nama-pigments angathonya i-hydrophilicity. Ukuze kuncishiswe ama-blistering nokuqina okuphansi, ukulawula izakhiwo ze-hydrophilic zezingubo eziphuma emanzini kubalulekile ukuvimbela ukuthathwa kwamanzi ngokweqile ngefilimu "eyomile". Ngakolunye uhlangothi, ukushisa okuphezulu nomswakama omncane kungaholela ekukhishweni kwamanzi ngokushesha, ikakhulukazi ekwakhiweni kwe-low-VOC, okunomthelela ekusebenzeni kanye nekhwalithi yokumboza.
