Zomwe zimalimbitsa ndizo mafupa othandizira aMtengo wa FRP , zomwe zimatsimikizira momwe zimapangidwira zamtundu wa pultruded. Kugwiritsiridwa ntchito kwa zinthu zolimbikitsira kumakhalanso ndi zotsatira zina pa kuchepetsa kuchepa kwa mankhwala ndi kuonjezera kutentha kwa kutentha kwa kutentha ndi mphamvu yochepa ya kutentha.
Popanga zinthu za FRP, kusankha kwa zida zolimbikitsira kuyenera kuganizira mozama momwe zimapangidwira, chifukwa mtundu, njira yoyakira ndi zomwe zili muzinthu zolimbikitsira zimakhudza kwambiri magwiridwe antchito a zinthu za FRP, ndipo zimatsimikizira makinawo. mphamvu ndi zotanuka modulus wa zinthu FRP. Magwiridwe azinthu zopangidwa ndi pultruded pogwiritsa ntchito zida zolimbikitsira zosiyanasiyana ndizosiyana.
Kuonjezera apo, pokwaniritsa zofunikira zogwirira ntchito pakupanga mapangidwe, mtengowo uyenera kuganiziridwanso, ndipo zipangizo zochepetsera zotsika mtengo ziyenera kusankhidwa momwe zingathere. Nthawi zambiri, kuzungulira kosapindika kwa ulusi wa magalasi kumakhala kotsika mtengo kuposa nsalu za ulusi; mtengo wakumva ndi wotsika kuposa wansalu, ndipo kusakwanira ndikwabwino. koma mphamvu ili yochepa; ulusi wa alkali ndi wotsika mtengo kuposa ulusi wopanda alkali, koma ndi kuchuluka kwa alkali, kukana kwake kwa alkali, kukana dzimbiri ndi mphamvu zamagetsi zidzachepa.
Mitundu ya zida zolimbikitsira zomwe zimagwiritsidwa ntchito kwambiri ndi izi:
1. Wosapindika Wagalasi Fiber Roving
Pogwiritsa ntchito chowonjezera chowonjezera, chozungulira chagalasi chosapindika chikhoza kugawidwa m'mitundu itatu: chingwe chopindika, chozungulira chosapindika komanso chozungulira chosapindika.
Chifukwa cha kusagwirizana kosagwirizana kwa zingwe za plied, zimakhala zosavuta kugwedezeka, zomwe zimapanga phokoso lotayirira kumapeto kwa chakudya cha zida za pultrusion, zomwe zimakhudza kuyenda bwino kwa ntchitoyo.
Ma mayendedwe osapindika olunjika amakhala ndi mawonekedwe akumanga bwino, kulowa mwachangu kwa utomoni, komanso makina abwino kwambiri azinthu, kotero ambiri aiwo amakonda kugwiritsa ntchito ma rovings osapindika pakadali pano.
Kuyenda mozungulira kopitilira muyeso ndikopindulitsa kupititsa patsogolo kulimba kwa zinthu, monga crimped roving ndi air-textured roving. Kuthamanga kwachulukidwe kumakhala ndi mphamvu yayikulu ya ulusi wautali wopitilira komanso kuchuluka kwa ulusi wamfupi. Ndizinthu zomwe zimakhala ndi kutentha kwakukulu, kutsika kwamafuta otsika, kukana kwa dzimbiri, mphamvu zambiri komanso kusefa kwakukulu. Ulusi wina umachulukitsidwa kukhala monofilament state, kotero ukhozanso kupititsa patsogolo mtundu wa zinthu zopangidwa ndi pultruded. Pakalipano, ma rovings ochuluka akhala akugwiritsidwa ntchito kwambiri kunyumba ndi kunja, monga ulusi wopota ndi wopota wa nsalu zokongoletsera kapena mafakitale. Itha kugwiritsidwa ntchito kupanga zinthu zokangana, zotsekemera, zoteteza kapena zosindikiza.
Zofunikira pakuchita kwa untwisted glass fiber roving for pultrusion:
(1) Palibe chodabwitsa
(2) Uniform CHIKWANGWANI chipwirikiti
(3) Kulumikizana bwino
(4) Kukana kuvala bwino
(5) Kuthyoka Mitu yocheperako, yosavuta kufota
(6) Good wettability ndi kudya utomoni impregnation
(7) Mphamvu zapamwamba ndi kukhazikika.
2. Fiberglass Mat
Kuti zinthu za FRP zopukutidwa zikhale ndi mphamvu zokwanira zopingasa, ndikofunikira kugwiritsa ntchito zida zolimbikitsira monga ma strand mat odulidwa, mphasa wopitilira, mphasa wophatikizika, ndi nsalu yozungulira. Continuous strand mat ndi chimodzi mwazinthu zomwe zimagwiritsidwa ntchito kwambiri pagalasi fiber transverse reinforcement pakali pano. Pofuna kupititsa patsogolo maonekedwe a zinthu, mat pamwamba nthawi zina amagwiritsidwa ntchito.
Ulusi wa strand wopitirira umapangidwa ndi zigawo zingapo za ulusi wagalasi wosalekeza womwe umayikidwa mozungulira mozungulira, ndipo ulusiwo umamangirizidwa ndi zomatira. Pamwamba pake ndi minofu yopyapyala yonga mapepala yopangidwa mwachisawawa komanso mofanana kuika zingwe zodulidwa zautali wokhazikika ndikumangirira ndi zomatira. Zomwe zimakhala ndi fiber ndi 5% mpaka 15%, ndipo makulidwe ake ndi 0.3 mpaka 0.4 mm. Ikhoza kupanga pamwamba pa mankhwala kuti ikhale yosalala komanso yokongola, ndikuwongolera kukana kukalamba kwa mankhwalawa.
Makhalidwe a galasi fiber mat ndi: kuphimba bwino, kosavuta kudzaza ndi utomoni, komanso zomatira zambiri.
Zofunikira pakupanga pultrusion pamagalasi a fiber mat:
(1) Lili ndi mphamvu zamakina apamwamba
(2) Kwa mateti opangidwa ndi mankhwala opangidwa ndi mankhwala, chomangiracho chiyenera kukhala chosagwirizana ndi zotsatira za mankhwala ndi matenthedwe panthawi ya kuviika ndi preforming kuti zitsimikizire mphamvu zokwanira panthawi yopanga.
(3) Kunyowa bwino
(4) Kuchepa kwa fluff ndi kung'ambika pang'ono / malekezero
3.PolyesterFiberSnkhopeMinofu
Polyester CHIKWANGWANI pamwamba minofu ndi mtundu watsopano wa kulimbikitsa CHIKWANGWANI mu makampani pultrusion. Pali chinthu chotchedwa Nexus ku United States, chomwe chimagwiritsidwa ntchito kwambiri muzinthu zopangidwa ndi pultruded m'malo mwa magalasi a fiber pamwamba mats / minofu / ubweya. Imakhala ndi zotsatira zabwino komanso zotsika mtengo. Zakhala zikugwiritsidwa ntchito bwino kwa zaka zoposa 10.
Ubwino wogwiritsa ntchito minofu ya polyester fiber surface:
(1) Itha kusintha kukana kwamphamvu, kukana kwa dzimbiri komanso kukana kukalamba kwamlengalenga kwa chinthucho
(2) Ikhoza kupititsa patsogolo mawonekedwe a chinthucho ndikupangitsa kuti pamwamba pake ikhale yosalala
(3) Polyester CHIKWANGWANI pamwamba minofu, ndi kukakamira ntchito ndi kumakoka ntchito bwino kuposa C galasi pamwamba minofu / mphasa, ndipo n'kosavuta kuswa mapeto pa ndondomeko pultrusion, kuchepetsa magalimoto magalimoto.
(4) Ikhoza kusintha liwiro la pultrusion
(5) Itha kuchepetsa kuvala kwa nkhungu ndikuwongolera moyo wautumiki wa nkhungu.
4. GalasiCloti/Tnyani
Muzinthu zina zapadera za pultruded, pofuna kukwaniritsa zofunikira zina zapadera, nsalu zamagalasi zokhala ndi m'lifupi mwake ndi makulidwe osakwana 0.2mm zimagwiritsidwa ntchito, ndipo mphamvu zake zowonongeka ndi mphamvu zodutsa zimakhala zabwino kwambiri.
5. Kugwiritsa ntchitoTwo-dimensionalFmalaya& Atatu-yam'mbaliFmalaya
Zopingasa zamakina azinthu zopangidwa ndi pultruded kompositi ndizosauka. Kugwiritsa ntchito njira ziwiri zoluka bwino kumalimbitsa mphamvu ndi kuuma kwa zinthu zopangidwa ndi pultruded.
Nsalu zopindika ndi zoluka za nsalu yolukidwa imeneyi sizimangirirana, koma zimalumikizana ndi nsalu ina, motero zimakhala zosiyana kotheratu ndi nsalu yagalasi yachikale. Ulusi kumbali iliyonse uli mumtundu wosakanikirana ndipo sumapanga kupindika kulikonse, motero mphamvu ndi kuuma kwa mankhwala opangidwa ndi pultruded, ndi apamwamba kwambiri kuposa a gulu lopangidwa ndi kumverera kosalekeza. Pakali pano, njira zitatu kuluka luso wakhala wokongola kwambiri ndi yogwira chitukuko chitukuko munda mu gulu zipangizo makampani. Malingana ndi zofunikira zolemetsa, ulusi wolimbikitsa umakulungidwa mwachindunji mumpangidwe wokhala ndi mawonekedwe atatu, ndipo mawonekedwe ake ndi ofanana ndi mawonekedwe a mankhwala ophatikizika omwe amapanga. Nsalu zanjira zitatu zomwe zimagwiritsidwa ntchito popanga pultrusion zimatha kuthana ndi kukameta ubweya wa interlaminar wazinthu zachikhalidwe zolimbikitsira fiber pultrusion. Ili ndi kuipa kwa mphamvu yotsika yometa ubweya komanso delamination yosavuta, ndipo magwiridwe ake a interlayer ndi abwino kwambiri. (Chitsime: Fiberglass Composites / Composites Community)
