Umata we-fiberglass: Kungumkhiqizo ofana neshidi owenziwe ngemicu eqhubekayo noma imicu eqoshiwe engaqondiswa yizinto ezibophayo zamakhemikhali noma isenzo somshini.

Izidingo zokusetshenziswa:

Ukubeka isandla phezulu:Ukubeka izandla kuyindlela eyinhloko yokukhiqiza i-FRP ezweni lakithi.Omata bezintambo eziqoshiwe zefayibha yengilazi, Ama-constant mat kanye nama-stitched mat angasetshenziswa ekubekeni ngesandla. Ukusetshenziswa kwe-stitch-bonded mat kunganciphisa inani lezendlalelo futhi kuthuthukise ukusebenza kahle kwemisebenzi yokubeka ngesandla. Kodwa-ke, ngenxa yokuthi i-stitch bonded mat iqukethe izintambo eziningi ze-fibre stitch bonding, ama-bubble akulula ukuwaxosha, imikhiqizo ye-FRP inama-bubble amaningi anomumo wenaliti, futhi ubuso buzwakala bunzima futhi bungasheleli. Ngaphezu kwalokho, i-stitched felt iyindwangu esindayo, futhi isembozo sesikhunta sifushane kunese-cut mat kanye ne-constant mat. Lapho wenza imikhiqizo enezimo eziyinkimbinkimbi, kulula ukwakha izikhala lapho kugoba khona. Inqubo yokubeka ngesandla idinga ukuthi i-mat ibe nezici zesivinini sokungena kwe-resin okusheshayo, ukususa kalula ama-bubbles omoya, kanye nokumbozwa okuhle kwesikhunta.

Ukuchitheka:Inqubo ye-pultrusion ingenye yezindlela ezisetshenziswa kakhulu kuma-constant ne-stitch-bond. Ngokuvamile, isetshenziswa kanye ne-roving engasontiwe. Ukusebenzisa ama-constant ne-stitched mat njengemikhiqizo ye-pultruded kungathuthukisa kakhulu i-hoop kanye namandla ajikelezayo emikhiqizo futhi kuvimbele imikhiqizo ekuqhekekeni. Inqubo ye-pultrusion idinga ukuthi i-mat ibe nokusatshalaliswa okufanayo kwe-fiber, amandla aphezulu okudonseka, izinga lokungena kwe-resin okusheshayo, ukuguquguquka okuhle kanye nokugcwaliswa kwesikhunta, futhi i-mat kufanele ibe nobude obuthile obuqhubekayo.

I-RTM:I-Resin Transfer Molding (RTM) inqubo yokubumba isikhunta evaliwe. Yakhiwe yizingxenyana ezimbili zesikhunta, isikhunta sowesifazane nesikhunta sowesilisa, iphampu yokucindezela kanye nesibhamu sokujova, ngaphandle kokucindezela. Inqubo ye-RTM ngokuvamile isebenzisa omata abaqhubekayo nabathungiwe esikhundleni somata abaqoshiwe. Kuyadingeka ukuthi ishidi lekhunta libe lula ukuligcwalisa nge-resin, ukungena kahle komoya, ukumelana okuhle nokukhuhla i-resin kanye nokuguguleka okuhle.

Inqubo yokugoqa: omata abaqoshiwe kanye nama-constant mat ngokuvamile asetshenziselwa ukugoqa nokwenza izendlalelo ezicebile nge-resin ezisetshenziswa kakhulu njengemikhiqizo, kufaka phakathi izendlalelo zangaphakathi kanye nezendlalelo zangaphandle. Izidingo ze-glass fiber mat enqubweni yokugoqa zifana kakhulu nalezo ezisendleleni yokubeka ngesandla.

Ukubunjwa kwe-Centrifugal casting: umbhede wezintambo oqoshiweivame ukusetshenziswa njengezinto zokusetshenziswa. Uhlaka oluqoshiwe lufakwa kusengaphambili esikhumbeni, besei-resinifakwa emgodini wesikhunta ovulekile ojikelezayo, futhi amabhamuza omoya akhishwa nge-centrifugation ukuze umkhiqizo ube mkhulu. Ingcezu yokubhoboza iyadingeka ukuze ibe nezici zokungena kalula kanye nokungena kahle komoya.

Inqubo eyingqayizivele yokukhiqiza umata wobuso befayibha yengilazi inquma ukuthi inezinzuzo zobuso obuyisicaba, ukusatshalaliswa okufanayo kwemicu, ukuzwakala kwesandla okuthambile, ukungena kahle komoya, kanye nesivinini sokungena kwe-resin okusheshayo. Imininingwane isukela ku-15g/m² kuya ku-100g/m². Izingxenye namagobolondo kuyizinto ezidingekayo zamapayipi e-FRP kanye nemikhiqizo ye-FRP.
