I-resin ye-epoxy ngokubanzi ibhekisa kwikhompawundi yepolymer ephilayo enamaqela amabini okanye ngaphezulu epoxy kwimolekyuli kwaye yenza i-dimensional crosslinked network ye-crosslinked imveliso ephilisiwe phantsi kwentshukumo yee-agent zeekhemikhali ezifanelekileyo.Ngaphandle kwabambalwa, ubunzima bayo bemolekyuli abukho phezulu.I-epoxy resin yamanzi yinkqubo ye-dispersion ezinzileyo elungiselelwe ngokusasaza i-epoxy resin emanzini ngendlela yeengqungquthela, amaconsi okanye i-colloids.I-epoxy resin yasemanzini inamandla okubuyisela izinto ezincamathelayo ezisekwe kwi-solvent, kwaye ibhetele ngakumbi kunezinto zokuncamathelisa ezisekelwe kwi-solvent kwezinye iimeko.I-epoxy resin yasemanzini isetyenziswa ikakhulu kwiindawo zemoto, uloliwe, ezolimo, izikhongozeli, iilori kunye nezinye izinto ezikhuselayo.Inoluhlu olubanzi lwezicelo kunye nethemba elihle lophuhliso lwamashishini.
I-resin epoxy yamanzi isetyenziswa kakhulu kwindawo yokwaleka.Ngaphantsi kwendlela jikelele yokhuseleko lokusingqongileyo lwehlabathi, imfuno yesicelo se-epoxy resin ephuma emanzini iyaqhubeka nokunyuka.Ngo-2020, ingeniso yemarike ye-epoxy resin yehlabathi ifikelele kwi-US $ 1122 yezigidi, kwaye kulindeleke ukuba ifike kwi-US $ 1887 yezigidi ngo-2027, kunye neqondo lokukhula kwekhompawundi yonyaka ye-7.36% (2021-2027).
Kule minyaka imbalwa idlulileyo, i-China ikhuthaze ngenkuthalo uhlaziyo lwezingxobo zekhonteyina kwaye yaguqula imarike yokugquma iikhonteyina ukusuka kwiityale ezisekwe kwi-solvent ukuya kwiiyaleko ezisekwe emanzini ukunciphisa ukukhutshwa kwezinyibilikisi.Imfuno yesicelo se-epoxy resin esekwe emanzini iyaqhubeka nokukhula.Ngo-2020, isikali semarike ye-epoxy resin yase-China esekwe emanzini imalunga ne-32.47 yezigidi zeeyuan, kwaye kulindeleke ukuba ifikelele malunga ne-50 yezigidi zeeyuan ngo-2025, ngesantya sokukhula komdibaniso wonyaka nge-7.9% (2021-2027).Ngokukhula kwemfuno yemarike, imveliso ye-epoxy resin yamanzi e-China iye yanda ukusuka kwi-95000 yeetoni ngo-2016 ukuya kwiitoni ze-120000 ngo-2020, kunye nesantya sokukhula esiphakathi kwe-5.8%.
I-epoxy resin yasemanzini ayinabungozi kokusingqongileyo ngenxa yokukhupha i-VOC.Ke ngoko, ezi resins zisetyenziswa ngokubanzi kwimizi-mveliso yokwaleka kunye nokuncamathelisa.Ukukhula kwemarike kuchatshazelwa kakhulu yimithetho engqongqo ye-EU.Ngokomzekelo, ngokwe-European Conference Directive 2004 / 42 / EC, ukukhutshwa kwe-volatile organic compounds (VOCs) kuthintelwe ngenxa yokusetyenziswa kwe-solvents yezinto eziphilayo kwiipende zokuhombisa kunye ne-varnish kunye nokusetyenziswa kwepeyinti ye-automotive touch-up.
Ehlabathini lonke, iingubo zisesona sicelo sibalulekileyo se-epoxy resins ephuma emanzini.Ngo-2019, i-56.64% ye-epoxy resins ephuma emanzini isetyenzisiwe kwimveliso ye-coatings, i-18.27% kwimveliso yezinto ezidibeneyo, kunye ne-21.7% yokusetyenziswa kokunamathela.
Ngokubhekiselele kuphuhliso, ngophuhliso lwemveliso kunye noshishino, imfuno ye-epoxy resin ephuma emanzini kwimoto, ulwakhiwo, ifenitshala, amalaphu kunye namanye amasimi iyaqhubeka nokukhula, kwaye intsimi yokwakha yeyona ndawo ikhula ngokukhawuleza yesicelo.Nangona kunjalo, ngophuhliso lweemoto ezikrelekrele kunye nezonga amandla kwixesha elizayo, ishishini leemoto liya kuqhubeka likhula, ngoko ke ithemba lesicelo se-epoxy resin ephuma emanzini kwintsimi yeemoto lilungile.
Ngokubhekiselele kukhuphiswano lwentengiso, ukhuphiswano phakathi kwabavelisi be-epoxy resin emanzini kwimarike yehlabathi lubukhali.I-epoxy resin yamanzi ineenzuzo zokusingqongileyo kunye noluhlu olubanzi lwezicelo.Kwiminyaka yakutshanje, imfuno yeemarike iqhubekile nokunyuka.Kwixesha elizayo, eliqhutywa luphuhliso lwezakhiwo ze-terminal, iimoto kunye namanye amashishini, imfuno yemarike ye-epoxy resin yamanzi iya kuqhubeka ikhula.
