1. Ntchito minda ya vinilu utomoni
Ndi mafakitale, msika wapadziko lonse lapansi wa vinyl resin umagawika m'magulu atatu: zophatikizika, utoto, zokutira, ndi zina.Vinyl resin matrix composites amagwiritsidwa ntchito kwambiri pamapaipi, akasinja osungira, zomangamanga, zoyendera ndi mafakitale ena.
Kukana kwa dzimbiri kwa vinyl resin komanso mawonekedwe abwino kwambiri amthupi ndi mankhwala kumapangitsa kukhala chinthu chosankhidwa pama projekiti ambiri a anti-corrosion FRP.Monga galasi CHIKWANGWANI analimbitsa pulasitiki akasinja, mapaipi, nsanja ndi dzimbiri zosagwira grilles, etc.;mapulojekiti odana ndi dzimbiri, monga pansi kwambiri zosagwira dzimbiri, zinthu zamphamvu za FRP;heavy-duty anti-corrosion glass flake zokutira, flake simenti;mphamvu chomera desulfurization ndi odana ndi dzimbiri, kutentha kukana, amphamvu asidi kukana Mphamvu alkali;Chemical workshop workbench acid ndi alkali kukana, kukana kutentha kwa dzimbiri, etc.
M'zaka zaposachedwa, ndi luso ndi chitukuko cha magwiridwe antchito apadera a vinyl ester resin, yapeza ntchito zina zatsopano m'minda yambiri yakumunsi:
1) Vinyl ester resin glass flake simenti yakhala ikukwezedwa bwino ndikugwiritsidwa ntchito m'munda wa gasi wa flue desulfurization m'mafakitale osatentha kwambiri, makamaka m'munda wa matanki a dziwe m'makampani opanga mankhwala.
2) Zovala zapamwamba za vinyl ester resin, kuphatikizapo zokutira za flake ndi zokutira zopanda flake, zalimbikitsidwa kwambiri ndikugwiritsidwa ntchito;300μm filimu makulidwe vinyl ester utomoni zokutira ayamba msika ndi kusonyeza mchitidwe kukula mofulumira;
3) Vinyl ester resin yokhala ndi index yayikulu ya okosijeni komanso utsi wochepa wautsi wadziwika ndikugwiritsidwa ntchito m'munda wa FRP wokhala ndi kukana kwa dzimbiri komanso kutentha kwamoto;

4) Vinyl ester resin yokhala ndi zero shrinkage ndi kulimba kwakukulu kwalimbikitsidwa kwambiri ndikugwiritsidwa ntchito mu zisoti za FRP, ndodo za usodzi ndi minda ina;
5) Vinyl ester resin yokhala ndi mphamvu zambiri komanso kutalika kwakukulu kwalimbikitsidwa kwambiri ndikugwiritsidwa ntchito m'munda wa magawo a FRP omwe ali ndi zofunikira zapadera;
6) Special functionalized vinilu ester utomoni ndi kopitilira muyeso kutentha kukana (pamwamba 200 ℃ mu mpweya gawo) ndi kopitilira muyeso-otsika kutentha kukana (-40 ℃) wakhala kutchuka ndi ntchito;
7) Vinyl ester resin yakhala ikudziwika ndikugwiritsidwa ntchito pazinthu zamagetsi zapadera (monga insulating FRP kwa locomotives, semiconductor carbon rods, etc.);

2. Ntchito yogwiritsira ntchito epoxy resin
Zabwino kwambiri zakuthupi, zamakina ndi zamagetsi zotchinjiriza za epoxy resin, zomangira zake ndi zida zosiyanasiyana, komanso kusinthasintha kwa kagwiritsidwe ntchito kake sizipezeka m'mapulasitiki ena a thermosetting.Chifukwa chake, zitha kupangidwa kukhala zokutira, zida zophatikizika, zoponya, zomatira, zomangira ndi zida zomangira jekeseni, ndipo zimagwiritsidwa ntchito kwambiri m'magawo osiyanasiyana azachuma chadziko.

①Kupaka utoto
Kugwiritsa ntchito utomoni wa epoxy mu zokutira kumakhala ndi gawo lalikulu, ndipo kumatha kupangidwa kukhala mitundu yokhala ndi mawonekedwe ndi ntchito zosiyanasiyana.Zomwe zimafanana: 1) Kukana kwabwino kwa mankhwala, makamaka kukana kwa alkali;2) Kumamatira mwamphamvu kwa filimu ya utoto, makamaka kuzitsulo;3) Kukana kutentha kwabwino komanso kutsekemera kwamagetsi;4) Kusunga utoto wamtundu wa filimu Kugonana ndikwabwino.
Zovala za epoxy resin zimagwiritsidwa ntchito makamaka ngati utoto woletsa kuwononga, zoyambira zitsulo, ndi utoto wotsekereza, koma zokutira zopangidwa ndi heterocyclic ndi alicyclic epoxy resins zitha kugwiritsidwa ntchito panja.
②Zomatira
Zomatira za epoxy ndi mitundu yofunikira ya zomatira zamapangidwe.Kuwonjezera pa kusamata bwino kwa mapulasitiki omwe si a polar monga polyolefins, epoxy resin imakhalanso yoyenera pazinthu zosiyanasiyana zazitsulo monga aluminiyamu, chitsulo, chitsulo, mkuwa;zinthu zopanda zitsulo monga galasi, matabwa, konkire, etc.;ndi pulasitiki thermosetting monga phenolic , amino, unsaturated poliyesitala, etc. ali ndi makhalidwe abwino adhesion, choncho amatchedwa universal guluu.
③ Zipangizo zamagetsi ndi zamagetsi
Chifukwa cha ntchito yake yotchinjiriza kwambiri, mphamvu zamapangidwe apamwamba komanso magwiridwe antchito abwino osindikizira ndi zabwino zina zambiri, utomoni wa epoxy wakhala ukugwiritsidwa ntchito kwambiri pakutchinjiriza ndi kuyika zida zamagetsi zamagetsi apamwamba komanso otsika, ma mota ndi zida zamagetsi, ndipo zakula mwachangu.
Amagwiritsidwa ntchito makamaka pa: 1) kuthira magetsi ndi magalimoto otchinjiriza phukusi;2) potting kutchinjiriza zipangizo ndi zigawo zamagetsi ndi mabwalo.3) Electronic grade epoxy akamaumba pawiri ntchito pulasitiki kusindikiza zigawo semiconductor;4) Kuphatikiza apo, mapulasitiki a epoxy laminated, zokutira zotchingira epoxy, zomatira zotchingira, ndi zomatira zamagetsi zimagwiritsidwanso ntchito kwambiri.
④Kupanga mapulasitiki ndi zida zophatikizika
Mapulasitiki a uinjiniya wa epoxy makamaka amaphatikiza ma epoxy akamaumba ndi ma epoxy laminates opangira kuthamanga kwambiri, komanso thovu la epoxy.Mapulasitiki a epoxy engineering amathanso kuwonedwa ngati zinthu zophatikizika za epoxy.Epoxy composite chuma ndi zofunika structural zakuthupi ndi zinchito mu makampani mankhwala, ndege, Azamlengalenga, asilikali ndi zina zamakono minda.
⑤Zida zomangira anthu
Pantchito yomanga, utomoni wa epoxy umagwiritsidwa ntchito makamaka ngati pansi odana ndi dzimbiri, matope a epoxy ndi zinthu za konkire, msewu wapamwamba kwambiri ndi msewu wa ndege, kukonza zinthu mwachangu, zopangira zopangira zolimbitsa maziko, zomatira zomanga ndi zokutira, etc.
