M'zaka zaposachedwa, pakhala pali chidwi chochulukirachulukira pakukhazikika komanso udindo wa chilengedwe, zomwe zimapangitsa kuti pakhale kufunikira kwakukulu kwa zokutira zochokera kumadzi. Izi zimathandizidwanso ndi zowongolera zomwe cholinga chake ndi kuchepetsa kutulutsa kwa VOC ndikulimbikitsa njira zina zokomera chilengedwe.
Msika wa zokutira zokhala ndi madzi akuyembekezeka kukula kuchokera pa EUR 92.0 biliyoni mu 2022 kufika pa EUR 125.0 biliyoni pofika 2030, kuwonetsa chiwonjezeko chapachaka cha 3.9%. Makampani opanga zokutira pamadzi akupitilizabe kupanga zatsopano, kupanga mapangidwe atsopano ndi matekinoloje kuti apititse patsogolo magwiridwe antchito, kulimba, komanso kugwiritsa ntchito bwino. Pamene kukhazikika kumayamba kufunikira pazokonda za ogula ndi zofunikira pakuwongolera, msika wa zokutira zotengera madzi ukuyembekezeka kupitiliza kukula.
M'misika yomwe ikubwera ya dera la Asia-Pacific (APAC), pakufunika kwambiri zokutira zotengera madzi chifukwa cha magawo osiyanasiyana a chitukuko cha zachuma komanso mafakitale osiyanasiyana. Kukula kwachuma kumayendetsedwa makamaka ndi kukula kwakukulu komanso kuyika ndalama zambiri m'mafakitale monga magalimoto, katundu wogula ndi zida zamagetsi, zomangamanga, ndi mipando. Derali ndi limodzi mwa madera omwe akukula mwachangu popanga komanso kufunikira kwa utoto wapamadzi. Kusankhidwa kwaukadaulo wa polima kumatha kusiyanasiyana kutengera gawo la msika lomwe likugwiritsidwa ntchito kumapeto komanso, kumlingo wina, dziko lomwe akugwiritsa ntchito. Komabe, zikuwonekeratu kuti dera la Asia-Pacific likusintha pang'onopang'ono kuchokera ku zokutira zachikhalidwe zosungunulira kupita ku zolimba kwambiri, zokhala ndi madzi, zokutira za ufa, ndi njira zochiritsira mphamvu.
Katundu wokhazikika komanso kufunikira kokulirapo m'misika yatsopano kumapanga mwayi
Katundu wa Eco-wochezeka, kulimba, komanso kukongola kwabwino kumawonjezera kugwiritsidwa ntchito pazinthu zosiyanasiyana. Ntchito zomanga zatsopano, kupentanso, ndikukula kwachuma m'misika yomwe ikubwera ndizinthu zazikulu zomwe zimapereka mwayi wokulirapo kwa omwe akutenga nawo gawo pamsika. Komabe, kuyambitsidwa kwa matekinoloje atsopano ndi kusakhazikika kwamitengo ya titanium dioxide kumabweretsa zovuta zazikulu.
Zovala za Acrylic resin (AR) ndi zina mwazovala zomwe zimagwiritsidwa ntchito kwambiri masiku ano. Izi zokutira ndi chinthu chimodzi-chinthu, makamaka preformed akiliriki ma polima kusungunuka mu zosungunulira ntchito pamwamba. Ma acrylic resins opangidwa ndi madzi amapereka njira zina zokomera zachilengedwe, kuchepetsa fungo ndi kugwiritsa ntchito zosungunulira pakupenta. Ngakhale zomangira zokhala ndi madzi nthawi zambiri zimagwiritsidwa ntchito popaka zokongoletsera, opanga apanganso ma emulsion opangidwa ndi madzi ndi ma dispersion resins omwe amapangidwira mafakitale monga ogula zamagetsi, magalimoto, ndi makina omanga. Acrylic ndi utomoni womwe umagwiritsidwa ntchito kwambiri chifukwa cha mphamvu zake, kuuma kwake, kukana kosungunulira bwino, kusinthasintha, kukana mphamvu, komanso kuuma kwake. Imawonjezera zinthu zapamtunda monga mawonekedwe, zomatira, komanso kunyowa ndipo imapereka dzimbiri komanso kukana zokanda. Ma resins a Acrylic adathandizira kuphatikiza kwawo kwa monomer kuti apange zomangira zamadzi za acrylic zoyenera kugwiritsa ntchito mkati ndi kunja. Zomangiriza izi zimatengera matekinoloje osiyanasiyana, kuphatikiza ma polima obalalika, ma polima athanzi, ndi ma polima a post-emulsified.
Ma Acrylic Resins Amasintha Mwachangu
Ndi malamulo ochulukirachulukira azachilengedwe, utomoni wa acrylic wamadzi wasanduka chinthu chomwe chikukula mwachangu chomwe chimagwiritsidwa ntchito mokhwima pazopaka zonse zokhala ndi madzi chifukwa chakuchita bwino. Kupititsa patsogolo mawonekedwe a utomoni wa acrylic ndikukulitsa mawonekedwe ake, njira zingapo zopangira ma polymerization ndi njira zapamwamba zosinthira acrylate zimagwiritsidwa ntchito. Zosinthazi zimayang'ana kuthana ndi zovuta zina, kulimbikitsa kukula kwa zinthu zopangidwa ndi madzi a acrylic resin, ndikupereka zinthu zabwino kwambiri. Kupita patsogolo, padzakhala kufunikira kosalekeza kukulitsa utomoni wa acrylic wamadzi kuti mukwaniritse magwiridwe antchito apamwamba, magwiridwe antchito ambiri, komanso mawonekedwe ochezeka.
Msika wa zokutira kudera la Asia-Pacific ukukula kwambiri ndipo ukuyembekezeka kupitiliza kukula chifukwa chakukula kwa magawo okhala, osakhalamo, komanso mafakitale. Dera la Asia-Pacific limaphatikizapo chuma chambiri pamagawo osiyanasiyana a chitukuko chachuma komanso mafakitale angapo. Kukula uku kumayendetsedwa makamaka ndi kukula kwachuma. Osewera otsogola akukulitsa kupanga kwawo zokutira zokhala ndi madzi ku Asia, makamaka ku China ndi India.
Shift in Production kupita kumayiko aku Asia
Mwachitsanzo, makampani apadziko lonse lapansi akusintha kupanga kumayiko aku Asia chifukwa cha kufunikira kwakukulu komanso kutsika kwamitengo yopangira, zomwe zimakhudza kukula kwa msika. Opanga otsogola amalamulira gawo lalikulu la msika wapadziko lonse lapansi. Mitundu yapadziko lonse lapansi monga BASF, Axalta, ndi Akzo Nobel pakadali pano ili ndi gawo lalikulu pamsika waku China wothira madzi. Kuphatikiza apo, makampani otchukawa padziko lonse lapansi akukulitsa luso lawo lokhala ndi madzi ku China kuti apititse patsogolo mpikisano wawo. Mu June 2022, Akzo Nobel adayika ndalama ku China kuti awonjezere mphamvu zoperekera zinthu zokhazikika. Makampani opanga zokutira ku China akuyembekezeka kukulirakulira chifukwa chakuchulukirachulukira kwazinthu zotsika za VOC, kupulumutsa mphamvu, komanso kuchepetsa utsi.
Boma la India lakhazikitsa njira ya "Make in India" yolimbikitsa kukula kwa mafakitale ake. Ntchitoyi ikuyang'ana magawo 25, kuphatikiza magalimoto, ndege, njanji, mankhwala, chitetezo, kupanga, ndi kunyamula. Kukula kwamakampani opanga magalimoto kumathandizidwa ndi kukwera kwachangu kwamatauni komanso kukula kwa mafakitale, kuchuluka kwa mphamvu zogulira, komanso kutsika kwamitengo yantchito. Kukula kwa opanga magalimoto akuluakulu mdziko muno komanso kuchuluka kwa ntchito zomanga, kuphatikiza mapulojekiti angapo ofunikira ndalama zambiri, kwadzetsa kukula kwachuma m'zaka zaposachedwa. Boma likuika ndalama muzomangamanga pogwiritsa ntchito ndalama zakunja (FDI), zomwe zikuyembekezeka kukulitsa bizinesi ya penti yopangidwa ndi madzi.
Msikawu ukupitilizabe kuwona kufunikira kwakukulu kwa zokutira zokondera zachilengedwe kutengera zinthu zachilengedwe. Zovala zokhala ndi madzi zikuyamba kutchuka chifukwa chakuchulukirachulukira pakukhazikika komanso malamulo okhwima a VOC. Kukhazikitsidwa kwa malamulo atsopano ndi malamulo okhwima, kuphatikiza zoyeserera monga European Commission's Eco-product Certification Scheme (ECS) ndi mabungwe ena aboma, zikugogomezera kudzipereka kulimbikitsa malo obiriwira komanso okhazikika omwe ali ndi mpweya wochepa kapena wopanda wowononga wa VOC. Malamulo aboma ku United States ndi Western Europe, makamaka omwe akuloza kuwononga mpweya, akuyembekezeka kupititsa patsogolo kukhazikitsidwa kwa matekinoloje atsopano opaka utsi wochepa. Potengera izi, zokutira zokhala ndi madzi zatuluka ngati VOC- komanso mayankho opanda lead, makamaka m'maiko okhwima monga Western Europe ndi US.
Pakufunika Patsogolo Patsogolo
Kuzindikira kwakukula kwaubwino wa utoto wokomera zachilengedwe uku kukuyendetsa kufunikira kwa mafakitale, nyumba zogona, komanso zomanga zosakhalamo. Kufunika kochita bwino komanso kulimba kwa zokutira zokhala ndi madzi ndikupititsa patsogolo chitukuko cha utomoni ndi matekinoloje owonjezera. Zovala zokhala ndi madzi zimateteza ndikuwonjezera gawo lapansi, zomwe zimathandizira kuti zikhazikike pochepetsa kugwiritsa ntchito zinthu zopangira ndikusunga gawo lapansi ndikupanga zokutira zatsopano. Ngakhale zokutira zokhala ndi madzi zimagwiritsidwa ntchito kwambiri, pali zovuta zaukadaulo zomwe zikuyenera kuthana nazo, monga kukulitsa kulimba.
Msika wa zokutira zam'madzi umakhalabe wampikisano kwambiri, wokhala ndi mphamvu zingapo, zovuta, ndi mwayi. Mafilimu opangidwa ndi madzi, chifukwa cha chikhalidwe cha hydrophilic cha resins ndi dispersants zomwe zimagwiritsidwa ntchito, amavutika kuti apange zotchinga zolimba ndikuthamangitsa madzi. Zowonjezera, zowonjezera, ndi zopaka utoto zimatha kusokoneza hydrophilicity. Kuti muchepetse matuza komanso kutsika kwanthawi yayitali, kuwongolera mawonekedwe a hydrophilic a zokutira zokhala ndi madzi ndikofunikira kuti muteteze madzi ochulukirapo ndi filimu "youma". Kumbali ina, kutentha kwambiri ndi chinyezi chochepa kungayambitse kuchotsedwa kwamadzi mwachangu, makamaka m'mitundu yotsika ya VOC, yomwe imakhudza kugwira ntchito komanso kuyanika bwino.
