Liaparo tsena ke lintho tse nang le karolo e le 'ngoe, haholo-holo li-polymers tsa acrylic tse entsoeng esale pele, tse qhibilihisitsoeng ka har'a li-solvents bakeng sa ho sebelisoa holimo. Li-resin tsa acrylic tse thehiloeng metsing li fana ka mefuta e meng e bonolo ea tikoloho, e fokotsa monko le tšebeliso ea mokelikeli nakong ea ho penta. Le hoja li-binders tse thehiloeng metsing li atisa ho sebelisoa liphahlo tse khabisitsoeng, bahlahisi ba boetse ba thehile li-emulsion tse nang le metsi le li-dispersion resin tse reretsoeng haholo liindasteri tse kang lisebelisoa tsa motlakase, tsa likoloi le tsa kaho. Acrylic ke resin e sebelisoang haholo ka lebaka la matla a eona, ho satalla, khanyetso e ntle ea ho qhibiliha, ho tenyetseha, ho hanyetsa tšusumetso, le ho thatafala.

Li-resin tsa Acrylic li kentse motsoako oa tsona oa monomer ho hlahisa li-binders tsa acrylic tse nang le metsi tse loketseng lisebelisoa tsa ka hare le tsa ka ntle. Li-binders tsena li ipapisitse le litheknoloji tse fapaneng, ho kenyelletsa le li-polymers tsa ho hasana, li-polymers tsa tharollo, le li-polymers tsa post-emulsified.
Li-resin tsa Acrylic li fetoha ka potlako
Ka melao le melaoana e ntseng e eketseha ea tikoloho, resin ea acrylic e thehiloeng metsing e fetohile sehlahisoa se ntseng se hola ka potlako se nang le ts'ebeliso e butsoitseng ka har'a liphahlo tsohle tse thehiloeng metsing ka lebaka la ts'ebetso ea eona e ntle haholo. Ho ntlafatsa thepa e akaretsang ea resin ea acrylic le ho holisa mefuta ea ts'ebeliso ea eona, ho sebelisoa mekhoa e fapaneng ea polymerization le mekhoa e tsoetseng pele ea phetoho ea acrylate. Liphetoho tsena li ikemiselitse ho sebetsana le liphephetso tse ikhethileng, ho khothaletsa kholo ea lihlahisoa tsa metsi a acrylic resin, le ho fana ka thepa e phahameng. Ha re fetela pele, ho tla ba le tlhoko e tsoelang pele ea ho nts'etsapele resin ea acrylic e thehiloeng metsing ho fihlela ts'ebetso e phahameng, ts'ebetso e mengata, le litšoaneleho tsa eco-friendly.
Mmaraka oa lirafshoa sebakeng sa Asia-Pacific o hola haholo mme o lebelletsoe ho tsoela pele ho hola ka lebaka la kholo ea makala a bolulo, a sa lulang le a indasteri. Sebaka sa Asia-Pacific se akaretsa mefuta e mengata ea moruo ka mekhahlelo e fapaneng ea nts'etsopele ea moruo le liindasteri tse ngata. Kholo ena e susumetsoa haholo-holo ke sekhahla se phahameng sa kholo ea moruo. Libapali tse ka sehloohong li ntse li atolosa tlhahiso ea tsona ea liphahlo tse entsoeng ka metsi Asia, haholo-holo Chaena le India.
Fetolela Tlhahisong ho ea Linaheng tsa Asia
Mohlala, lik'hamphani tsa lefats'e li fetolela tlhahiso linaheng tsa Asia ka lebaka la tlhokeho e phahameng le litšenyehelo tse tlase tsa tlhahiso, tse amang kholo ea mmaraka ka tsela e ntle. Baetsi ba ka sehloohong ba laola karolo e kholo ea 'maraka oa lefats'e. Lihlahisoa tsa machaba tse kang BASF, Axalta, le Akzo Nobel hajoale li na le karolo e kholo ea 'maraka oa China oa likhoele tsa metsi. Ho feta moo, lik'hamphani tsena tse hlahelletseng tsa lefats'e li ntse li holisa ka mafolofolo matla a tsona a ho koaheloa ke metsi China ho ntlafatsa tlholisano ea tsona. Ka Phuptjane 2022, Akzo Nobel o ile a tsetela mocheng o mocha oa tlhahiso China ho eketsa bokhoni ba ho fana ka lihlahisoa tse tšoarellang. Indasteri ea liphahlo tsa China e lebelletsoe ho hola ka lebaka la ho tsepamisa maikutlo ho eketsehileng ho lihlahisoa tse tlase tsa VOC, ho boloka matla le phokotso ea mosi.
Mmuso oa India o phatlalalitse morero oa "Make in India" ho khothaletsa kholo ea indasteri ea ona. Boikitlaetso bona bo tsepamisitse maikutlo makaleng a 25, ho kenyeletsoa makoloi, sefofane, literene, lik'hemik'hale, ts'ireletso, tlhahiso le ho paka. Keketseho ea indasteri ea likoloi e tšehetsoa ke ho ata ka potlako ha litoropo le indasteri, ho eketseha ha matla a ho reka, le litšenyehelo tse tlase tsa basebetsi.

Mmaraka o ntse o tsoela pele ho bona tlhokahalo e matla ea liphahlo tse nang le tikoloho tse thehiloeng ho lisebelisoa tse tala tsa tikoloho. Liaparo tse nang le metsi li ntse li tsebahala ka lebaka la ho tsepamisa maikutlo ho eketsehileng ho tsitsitseng le melao e thata ea VOC. Ho hlahisoa ha melao e mecha le melaoana e thata, ho kenyeletsoa matsapa a joalo ka Sekema sa Setifikeiti sa Eco-product (ECS) sa Khomishene ea Europe le mekhatlo e meng ea mmuso, e totobatsa boitlamo ba ho khothaletsa tikoloho e tala le e tšoarellang e nang le mesi e kotsi e fokolang kapa e se nang kotsi ea VOC.

Ho arabela mekhoa ena, liphahlo tsa metsi li hlahile e le litharollo tsa VOC-le tse se nang lead, haholo-holo moruong o holileng joalo ka Western Europe le US.
Ho Hlokahala Tsoelo-pele ea Bohlokoa
Tlhokomelo e ntseng e hola ea melemo ea lipente tsena tse sebetsang hantle ka tikolohong e ntse e hola tlhokeho ea makala a indasteri, a bolulo le a kaho eo e seng ea bolulo.

Le hoja liphahlo tse nang le metsi li sebelisoa haholo, ho ntse ho e-na le litaba tsa theknoloji tse lokelang ho rarolloa, tse kang ho ntlafatsa nako e telele.
Mmaraka oa likhoele tsa metsi o lula o le tlholisano e kholo, o na le matla, liphephetso le menyetla e mengata. Lifilimi tse thehiloeng metsing, ka lebaka la tlhaho ea hydrophilic ea li-resin le dispersants tse sebelisitsoeng, li loanela ho theha mekoallo e matla le ho leleka metsi. Li-additives, li-surfactants le li-pigment li ka ama hydrophilicity. E le ho fokotsa ho senya le ho theola nako e telele, ho laola thepa ea hydrophilic ea liaparo tse nang le metsi ke habohlokoa ho thibela ho kenngoa ha metsi a mangata ka filimi e "omileng". Ka lehlakoreng le leng, mocheso o phahameng le mongobo o tlase li ka lebisa ho phalloeng ha metsi ka potlako, haholo-holo ka lihlahisoa tse tlaase tsa VOC, tse amang ts'ebetso le boleng ba ho koahela.
