1. Kugwiritsa ntchito utomoni wa vinyl
Malinga ndi mafakitale, msika wapadziko lonse wa vinyl resin umagawidwa m'magulu atatu: zinthu zopangidwa ndi vinyl, utoto, zokutira, ndi zina. Zinthu zopangidwa ndi vinyl resin matrix zimagwiritsidwa ntchito kwambiri m'mapaipi, matanki osungiramo zinthu, zomangamanga, zoyendera ndi mafakitale ena.
Kukana dzimbiri kwa vinyl resin komanso mphamvu zake zakuthupi ndi zamakemikolo zimapangitsa kuti ikhale chinthu chofunikira kwambiri pa ntchito zambiri zotsutsana ndi dzimbiri za FRP. Monga matanki apulasitiki olimbikitsidwa ndi ulusi wagalasi, mapaipi, nsanja ndi ma grille osagonjetsedwa ndi dzimbiri, ndi zina zotero; ntchito zotsutsana ndi dzimbiri, monga pansi zosagonjetsedwa ndi dzimbiri, zinthu za FRP zolimba; zokutira zoteteza ku dzimbiri zagalasi, simenti yolimba yolimbana ndi dzimbiri; kuyeretsa kwa magetsi ndi kukana dzimbiri, kukana kutentha kwambiri, kukana asidi amphamvu. Alkali wamphamvu; kukana asidi ndi alkali wa mankhwala, kukana kutentha kwambiri, ndi zina zotero.
M'zaka zaposachedwa, ndi luso ndi chitukuko cha magwiridwe antchito apadera a vinyl ester resin, yapeza ntchito zatsopano m'magawo ambiri otsatira:
1) Simenti ya vinyl ester resin yagwiritsidwa ntchito bwino pochotsa mpweya woipa m'malo opangira magetsi osatentha, makamaka m'malo opangira thanki la dziwe m'makampani opanga mankhwala.
2) Zophimba za resin za vinyl ester zokhala ndi mapangidwe apamwamba, kuphatikizapo zophimba za flake ndi zophimba zopanda flake, zalimbikitsidwa kwambiri ndikugwiritsidwa ntchito; Zophimba za resin za vinyl ester resin za makulidwe a filimu a 300μm zayamba kugulitsidwa ndipo zikuwonetsa kukula mwachangu;
3) Utomoni wa vinyl ester wokhala ndi mpweya wambiri komanso utsi wochepa wagwiritsidwa ntchito kwambiri mu FRP yokhala ndi mphamvu yolimbana ndi dzimbiri komanso yoletsa moto;

4) Utomoni wa vinyl ester wopanda kufooka konse komanso kulimba kwambiri walimbikitsidwa kwambiri ndikugwiritsidwa ntchito mu zipewa za FRP, ndodo zosodza ndi madera ena;
5) Utomoni wa vinyl ester wokhala ndi mphamvu zambiri komanso kutalika kwakukulu walimbikitsidwa kwambiri ndikugwiritsidwa ntchito m'magawo a kapangidwe ka FRP okhala ndi zofunikira zapadera;
6) Utomoni wapadera wa vinyl ester wopangidwa ndi ntchito wokhala ndi kukana kutentha kwambiri (kupitirira 200℃ mu gawo la mpweya) komanso kukana kutentha kochepa kwambiri (-40℃) watchuka ndikugwiritsidwa ntchito;
7) Utomoni wa vinyl ester watchuka ndikugwiritsidwa ntchito pa zipangizo zamagetsi zapadera (monga kutchinjiriza FRP ya ma locomotive, ndodo za carbon semiconductor, ndi zina zotero);

2. Malo ogwiritsira ntchito utomoni wa epoxy
Mphamvu zabwino kwambiri zotetezera kutentha kwa epoxy resin, makina ndi magetsi, komanso mphamvu zake zolumikizirana ndi zinthu zosiyanasiyana, komanso kusinthasintha kwa njira yogwiritsira ntchito sizipezeka m'mapulasitiki ena otenthetsera kutentha. Chifukwa chake, imatha kupangidwa kukhala zokutira, zinthu zophatikizika, zinthu zoponyera, zomatira, zinthu zomangira ndi zinthu zopangira jekeseni, ndipo imagwiritsidwa ntchito kwambiri m'magawo osiyanasiyana azachuma cha dziko.

①Utoto
Kugwiritsa ntchito epoxy resin mu zokutira kumakhudza gawo lalikulu, ndipo kumatha kupangidwa m'mitundu yosiyanasiyana yokhala ndi mawonekedwe ndi ntchito zosiyanasiyana. Zinthu zake zodziwika bwino: 1) Kukana mankhwala bwino, makamaka kukana alkali; 2) Kumatirira mwamphamvu kwa utoto, makamaka ku zitsulo; 3) Kukana kutentha bwino komanso kutchinjiriza magetsi; 4) Kusunga utoto wa utoto. Kugonana ndikwabwino.
Zophimba za epoxy resin zimagwiritsidwa ntchito makamaka ngati utoto woletsa dzimbiri, zoyambira zachitsulo, ndi utoto woteteza kutentha, koma zophimba zopangidwa ndi ma resins a heterocyclic ndi alicyclic epoxy zitha kugwiritsidwa ntchito panja.
②Zomatira
Ma epoxy glue ndi mitundu yofunika kwambiri ya ma glue opangidwa ndi kapangidwe kake. Kuwonjezera pa kusagwira bwino ntchito ndi mapulasitiki osakhala a polar monga ma polyolefin, epoxy resin ndi yoyeneranso kugwiritsa ntchito zinthu zosiyanasiyana zachitsulo monga aluminiyamu, chitsulo, chitsulo, mkuwa; zinthu zosakhala zachitsulo monga galasi, matabwa, konkire, ndi zina zotero; ndipo mapulasitiki otenthetsera kutentha monga phenolic, amino, unsaturated polyester, ndi zina zotero ali ndi mphamvu zabwino zogwirira, motero amatchedwa guluu wapadziko lonse.
③ Zipangizo zamagetsi ndi zamagetsi
Chifukwa cha mphamvu zake zotetezera kutentha, mphamvu zake zomanga komanso kutseka bwino zinthu komanso ubwino wina wapadera, utomoni wa epoxy wakhala ukugwiritsidwa ntchito kwambiri poteteza kutentha ndi kulongedza zipangizo zamagetsi zamagetsi, ma mota ndi zida zamagetsi zamagetsi, ndipo wakula mofulumira.
Amagwiritsidwa ntchito makamaka pa: 1) kuthira ma phukusi amagetsi ndi oteteza magetsi; 2) kutchinjiriza zipangizo zamagetsi ndi ma circuits. 3) Chopangira cha epoxy chopangira magetsi chimagwiritsidwa ntchito potseka pulasitiki ya zigawo za semiconductor; 4) Kuphatikiza apo, mapulasitiki okhala ndi epoxy laminated, zokutira zoteteza epoxy, zomatira zoteteza magetsi, ndi zomatira zamagetsi zimagwiritsidwanso ntchito kwambiri.
④Mapulasitiki aukadaulo ndi zipangizo zophatikizika
Mapulasitiki a epoxy engineering makamaka amaphatikizapo zinthu zopangira epoxy ndi epoxy laminates zopangira makina oponderezedwa kwambiri, komanso thovu la epoxy. Mapulasitiki a epoxy engineering amathanso kuonedwa ngati zinthu zopangira epoxy. Zinthu zopangira epoxy ndi zinthu zofunika kwambiri pakupanga ndi ntchito m'makampani opanga mankhwala, ndege, ndege, asilikali ndi madera ena apamwamba.
⑤Zipangizo zomangira nyumba
Pa ntchito yomanga, epoxy resin imagwiritsidwa ntchito makamaka ngati pansi yoletsa dzimbiri, matope a epoxy ndi zinthu za konkire, malo apamwamba a msewu ndi bwalo la ndege, zinthu zokonza mwachangu, zinthu zopangira grouting zolimbitsa maziko, zomatira zomangira ndi zokutira, ndi zina zotero.
