1. Iindawo zokusetyenziswa kwe-vinyl resin
Ngokwemizi-mveliso, imakethi ye-vinyl resin yehlabathi yahlulwe kakhulu yaba ziindidi ezintathu: ii-composites, iipeyinti, ii-coating, kunye nezinye. Ii-vinyl resin matrix composites zisetyenziswa kakhulu kwimibhobho, kwiitanki zokugcina, kulwakhiwo, kwezothutho nakwamanye amashishini.
Ukumelana nokugqwala okugqwesileyo kwe-vinyl resin kunye neempawu ezintle zomzimba nezekhemikhali zenza ukuba ibe zizinto ezikhethwayo kwiiprojekthi ezininzi ze-FRP zekhemikhali ezichasene nokugqwala. Ezifana neetanki zeplastiki eziqinisiweyo zefayibha yeglasi, iipayipi, iinqaba kunye nee-grilles ezichasene nokugqwala, njl.njl.; iiprojekthi ezichasene nokugqwala, ezifana neemigangatho ezichasene nokugqwala okuphezulu, iimveliso ze-FRP ezinamandla aphezulu; iingubo zeglasi ezichasene nokugqwala ezinzima, isamente ye-flake; ukususwa kwe-sulfurization kunye nokuchasene nokugqwala, ukumelana nobushushu obuphezulu, ukumelana ne-asidi enamandla I-alkali enamandla; ukumelana ne-acid kunye ne-alkali kwi-workshop yekhemikhali, ukumelana nokugqwala kobushushu obuphezulu, njl.njl.
Kwiminyaka yakutshanje, ngokuveliswa kwezinto ezintsha kunye nophuhliso lwendlela ekhethekileyo yokusebenza kwe-vinyl ester resin, ifumene ezinye izicelo ezintsha kwiindawo ezininzi ezisezantsi:
1) Isamente yeglasi ye-vinyl ester resin ikhuthazwe kakuhle kwaye isetyenziswa kwicandelo lokucoca igesi yeflue kwizityalo zamandla ezingezizo ezobushushu, ingakumbi kwicandelo leetanki zedama lokudada kushishino lweekhemikhali.
2) Iingubo ze-vinyl ester resin ezakhiwe ngokuphezulu, kuquka iingubo ze-flake kunye neengubo ze-non-flake, ziye zakhuthazwa kwaye zasetyenziswa ngokubanzi; Iingubo ze-vinyl ester resin ze-vinyl ester ezinobukhulu befilimu obuyi-300μm ziqalile ukuthengiswa kwaye zibonisa umkhwa wokukhula ngokukhawuleza;
3) I-resin ye-vinyl ester ene-oxygen index ephezulu kunye noxinano oluphantsi lomsi iye yathandwa kwaye yasetyenziswa kwicandelo le-FRP enokumelana nokugqwala kunye nokuthintelwa komlilo;

4) I-resin ye-vinyl ester engenakuncipha kwaye iqine kakhulu ikhuthazwe kakhulu kwaye isetyenziswa kwizigcina-ntloko ze-FRP, iintonga zokuloba nakwezinye iindawo;
5) I-resin ye-vinyl ester enamandla aphezulu kunye nobude obuphezulu ikhuthazwe kakhulu kwaye isetyenziswa kwicandelo leendawo zesakhiwo ze-FRP ezineemfuno ezikhethekileyo;
6) I-resin ekhethekileyo ye-vinyl ester esebenzayo enokumelana nobushushu obuphezulu kakhulu (ngaphezulu kwama-200℃ kwisigaba segesi) kunye nokumelana nobushushu obuphantsi kakhulu (-40℃) iye yathandwa kwaye yasetyenziswa;
7) I-vinyl ester resin iye yathandwa kwaye yasetyenziswa kwicandelo lezixhobo zombane ezikhethekileyo (ezifana nokufaka i-FRP kwi-locomotives, ii-semiconductor carbon rods, njl.njl.);

2. Intsimi yokusetyenziswa kwe-epoxy resin
Iimpawu ezintle kakhulu zokufakelwa kwe-epoxy resin emzimbeni, ngoomatshini nangombane, iimpawu zayo zokubopha ngezinto ezahlukeneyo, kunye nokuguquguquka kwenkqubo yokusetyenziswa kwayo azifumaneki kwezinye iiplastiki ze-thermosetting. Ke ngoko, inokwenziwa ibe ziingubo, izinto ezidityanisiweyo, izinto zokuphosa, izincamathelisi, izinto zokubumba kunye nezinto zokubumba ngenaliti, kwaye isetyenziswa kakhulu kwiinkalo ezahlukeneyo zoqoqosho lwesizwe.

①Ipeyinti
Ukusetyenziswa kwe-epoxy resin kwiingubo kwenza inxalenye enkulu, kwaye inokwenziwa ibe ziintlobo ngeentlobo ezineempawu ezahlukeneyo kunye nokusetyenziswa. Iimpawu zayo eziqhelekileyo: 1) Ukumelana okugqwesileyo kweekhemikhali, ngakumbi ukumelana ne-alkali; 2) Ukunamathela okuqinileyo kwefilimu yepeyinti, ngakumbi kwiintsimbi; 3) Ukumelana okuhle nobushushu kunye nokufakwa kombane; 4) Ukugcinwa kombala wefilimu yepeyinti.
Iingubo ze-epoxy resin zisetyenziswa kakhulu njengeepeyinti zokulwa nokugqwala, ii-primer zesinyithi, kunye neepeyinti zokukhusela, kodwa iingubo ezenziwe ngee-heterocyclic kunye nee-alicyclic epoxy resins zingasetyenziswa ngaphandle.
②Inamathelayo
Izincamathelisi ze-epoxy ziluhlobo olubalulekileyo lwezincamathelisi zesakhiwo. Ukongeza ekunamatheleni kakubi kwiiplastiki ezingezizo iipolar ezifana neepolyolefins, i-epoxy resin ikwafanelekile kwizinto ezahlukeneyo zesinyithi ezifana ne-aluminium, intsimbi, isinyithi, ubhedu; izinto ezingezizo iimetallic ezifana neglasi, umthi, ikhonkrithi, njl.njl.; kwaye iiplastiki ze-thermosetting ezifana ne-phenolic, i-amino, i-unsaturated polyester, njl.njl. zineempawu ezibalaseleyo zokunamathela, ngoko ke ibizwa ngokuba yiglue yendalo yonke.
③ Izixhobo ze-elektroniki nezombane
Ngenxa yokusebenza kwayo okuphezulu kokugquma, amandla aphezulu olwakhiwo kunye nokusebenza kakuhle kokutywina kunye nezinye izibonelelo ezininzi ezikhethekileyo, i-epoxy resin isetyenzisiwe kakhulu ekugqumeni nasekupakisheni izixhobo zombane eziphezulu neziphantsi, iimoto kunye nezinto ze-elektroniki, kwaye iphuhlisiwe ngokukhawuleza.
Isetyenziswa kakhulu kwezi zinto zilandelayo: 1) ukuthulula iipakethe zokukhusela umbane kunye neemoto; 2) ukugquma izixhobo ezinezixhobo ze-elektroniki kunye neesekethe. 3) I-compound ye-epoxy yodidi lwe-elektroniki isetyenziselwa ukutywina iplastiki yezixhobo ze-semiconductor; 4) Ukongeza, iiplastiki ezifakwe i-epoxy laminated, ii-epoxy insulating coats, ii-insulating adhesives, kunye nee-adhesives zombane nazo zisetyenziswa kakhulu.
④Iiplastiki zobunjineli kunye nezinto ezidityanisiweyo
Iiplastiki zobunjineli be-epoxy ziquka ikakhulu iikhompawundi zokubumba ze-epoxy kunye nee-epoxy laminates zokubumba ngoxinzelelo oluphezulu, kunye nee-epoxy foams. Iiplastiki zobunjineli be-epoxy nazo zinokuthathwa njengezinto ezidityanisiweyo ze-epoxy. Izinto ezidityanisiweyo ze-epoxy zizinto ezibalulekileyo zokwakha kunye nezinto ezisebenzayo kushishino lweekhemikhali, kwiinqwelomoya, kwi-aerospace, emkhosini nakwamanye amacandelo obuchwepheshe obuphezulu.
⑤Izixhobo zokwakha zokwakha
