I-epoxy resin ngokuvamile ibhekisela kwinhlanganisela ye-polymer ephilayo enamaqembu e-epoxy amabili noma ngaphezulu ku-molecule futhi yakha umkhiqizo olashiwe wenethiwekhi enezinhlangothi ezintathu ezihlukene ngaphansi kwesenzo samakhemikhali afanelekile.Ngaphandle kwabambalwa, isisindo sayo samangqamuzana asikho phezulu.I-waterborne epoxy resin iwuhlelo oluzinzile lokuhlakazeka olulungiswe ngokuhlakaza inhlaka ye-epoxy emanzini ngendlela yezinhlayiya, amaconsi noma ama-colloid.I-epoxy resin etholakala emanzini inamandla aqinile wokushintsha izinto ezinamathelayo ezincibilikisiwe, futhi ingcono nakakhulu kunezinamathiselo ezisekelwe ku-solvent evamile kwezinye izimo.I-epoxy resin etholakala emanzini isetshenziswa kakhulu ezingxenyeni zezimoto, ujantshi, ezolimo, iziqukathi, amaloli nokunye okokuvikela.Inezinhlobonhlobo zezicelo kanye namathemba amahle okuthuthukiswa kwezimboni.
I-epoxy resin etholakala emanzini isetshenziswa kakhulu emkhakheni wokumboza.Ngaphansi komkhuba ojwayelekile wokuvikelwa kwemvelo emhlabeni wonke, isidingo sokufakwa kwamanzi epoxy resin siyaqhubeka nokukhuphuka.Ngo-2020, imali yemakethe ye-epoxy resin yomhlaba wonke yafinyelela ku-US $ 1122 wezigidi, futhi kulindeleke ukuthi ifinyelele ezigidini ezingama-US $1887 ngo-2027, ngesilinganiso sokukhula esiyinhlanganisela sonyaka esingu-7.36% (2021-2027).
Eminyakeni embalwa edlule, iShayina ikhuthaze ngenkuthalo ukuguqulwa kweziqukathi futhi yaguqula imakethe yokumboza iziqukathi isuka kwezincibilikayo iye kweyamanzi ukuze kuncishiswe ukukhishwa kwezinyibilikisi.Isidingo sokusetshenziswa kwe-epoxy resin esekwe emanzini siyaqhubeka nokukhula.Ngo-2020, isikali semakethe se-epoxy resin esekwe emanzini saseChina singama-yuan ayizigidi ezingama-32.47, futhi kulindeleke ukuthi sifinyelele cishe ama-yuan ayizigidi ezingama-50 ngo-2025, ngesilinganiso sokukhula esiyinhlanganisela yonyaka esingu-7.9% (2021-2027).Ngokukhula kwesidingo semakethe, ukukhiqizwa kwe-epoxy resin emanzini e-China nakho kukhuphuke kusuka kumathani angama-95000 ngo-2016 kuya kumathani ayi-120000 ngo-2020, ngesilinganiso sokukhula esimaphakathi esingu-5.8%.
I-epoxy resin etholakala emanzini ayinabungozi emvelweni ngenxa yokukhipha i-VOC eyiziro.Ngakho-ke, lawa ma-resin asetshenziswa kakhulu ezimbonini zokumboza nezokunamathela.Ukukhula kwemakethe kuthintwa kakhulu yimithetho eqinile ye-EU.Isibonelo, ngokwe-European Conference Directive 2004/42/EC, ukukhishwa kwezinhlanganisela eziphilayo ezishintshashintshayo (VOCs) kukhawulelwe ngenxa yokusetshenziswa kwezinyibilikisi zemvelo kumapende okuhlobisa namavashi kanye nokusetshenziswa kopende bokuthinta izimoto.
Emhlabeni jikelele, ukumbozwa kusewukusetshenziswa okubaluleke kakhulu kwama-epoxy resins aphuma emanzini.Ngo-2019, ama-56.64% ama-epoxy resins asetshenziswa emanzini asetshenziswa ekukhiqizeni okokunamathela, ama-18.27% ekukhiqizeni izinto eziyinhlanganisela, kanye nama-21.7% okusetshenziswa okuphelele kokunamathela.
Mayelana nentuthuko, ngokuthuthuka kwezokukhiqiza kanye nezimboni, isidingo se-epoxy resin etholakala emanzini emotweni, ekwakhiweni kwezakhiwo, ifenisha, kwezindwangu neminye imikhakha siyaqhubeka nokukhula, kanti inkambu yokwakha iyinkundla yesicelo ekhula ngokushesha kakhulu.Kodwa-ke, ngokuthuthukiswa kwezimoto ezihlakaniphile nezonga amandla esikhathini esizayo, imboni yezimoto izoqhubeka nokukhula, ngakho-ke ithemba lokufaka isicelo se-epoxy resin emanzini emkhakheni wezimoto lihle.
Mayelana nokuncintisana kwemakethe, ukuncintisana phakathi kwabakhiqizi be-epoxy resin basemanzini emakethe yomhlaba wonke kushubile.I-epoxy resin etholakala emanzini inezinzuzo zokuvikela imvelo kanye nezinhlelo eziningi zokusebenza.Eminyakeni yamuva, isidingo semakethe siqhubekile nokukhuphuka.Ngokuzayo, eqhutshwa ukuthuthukiswa kwezakhiwo zokugcina, izimoto kanye nezinye izimboni, isidingo semakethe se-epoxy resin etholakala emanzini sizoqhubeka nokukhula.
