Zomwe zimalimbitsa ndi mafupa othandizira azinthu za FRP, zomwe zimatsimikizira zomwe zimapangidwira.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 komanso 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, pamene akukwaniritsa zofunikira za ntchito ya mankhwala poumba, mtengowo uyenera kuganiziridwanso, ndipo zipangizo zochepetsera zotsika mtengo ziyenera kusankhidwa momwe zingathere.Nthawi zambiri, kusatolera kwa zingwe zamagalasi kumakhala kotsika mtengo kuposa nsalu za ulusi;mtengo wamagalasi a fiberndi otsika kuposa nsalu, ndipo kusalolera ndi kwabwino., 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. Osapindika galasi CHIKWANGWANI roving

Pogwiritsa ntchito zowonjezera zowonjezera, zosapindikagalasi fiber rovingakhoza kugawidwa m'magulu atatu: plied silika yaiwisi, molunjika osapindika, ndi bulked untwisted roving.

Chifukwa cha kusagwirizana kosagwirizana kwa zingwe za plied, zimakhala zosavuta kugwedezeka, zomwe zimapanga phokoso lotayirira kumapeto kwa chakudya cha pultrusion, zomwe zimakhudza kuyenda bwino kwa ntchitoyo.

Kuzungulira kosapindika kwachindunji kumakhala ndi mawonekedwe omanga bwino, kulowa mwachangu kwa utomoni, komanso makina abwino kwambiri azinthu, kotero kuti zozungulira zambiri zosapindika zimakonda kugwiritsidwa ntchito pakadali pano.

Kuzungulira kozungulira kumakhala kopindulitsa kupititsa patsogolo mphamvu zopingasa za zinthu, monga ma crimped rovings ndi ma rovings opangidwa ndi mpweya.Kuthamanga kwambiri kumakhala ndi mphamvu zambiri za ulusi wautali wautali komanso kuchuluka kwa ulusi waufupi.Ndizinthu zomwe zimakhala ndi kutentha kwambiri, kutsika kwamafuta, kukana kwa dzimbiri, mphamvu zambiri komanso kusefa kwakukulu.Ulusi wina umachulukitsidwa kukhala monofilament state, kotero ukhozanso kuwongolera pamwamba pa 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, zotsekereza, zoteteza kapena zosindikiza.

Zofunikira pakuchita kwa magalasi osapindika a fiber rovings a pultrusion:

(1) Palibe chodabwitsa;

(2) Kuvuta kwa ulusi ndi yunifolomu;

(3) Kusunga bwino;

(4) Kukana kuvala bwino;

(5) Pali mitu yochepa yothyoka, ndipo sikophweka kupukuta;

(6) Good wettability ndi kudya utomoni impregnation;

(7) Mphamvu zapamwamba ndi kukhazikika.

2. Magalasi CHIKWANGWANI mphasa

Kuti apange zinthu za FRP zokhala ndi mphamvu zokwanira zopingasa, zida zolimbikitsira monga mphasa wodulidwa, mphasa wopitilira, mphasa wophatikizika, ndi nsalu zosapindika ziyenera kugwiritsidwa ntchito.Continuous strand mat ndi chimodzi mwazinthu zomwe zimagwiritsidwa ntchito kwambiri pagalasi fiber transverse reinforcement pakali pano.Pofuna kukonza mawonekedwe azinthu,pamwamba matnthawi 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 amamveka ngati pepala lopyapyala ngati mawonekedwe opangidwa mwachisawawa komanso mofanana atayala 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 mankhwalawo kukhala osalala komanso okongola, ndikuthandizira kukana kukalamba kwa mankhwalawa.

Makhalidwe a galasi fiber mat ndi: kuphimba bwino, kosavuta kudzaza ndi utomoni, zomatira zambiri

Zofunikira pakupanga pultrusion pamagalasi a fiber mat:

(1) Ali ndi mphamvu zamakina apamwamba

(2) Kwa mateti opangidwa ndi mankhwala opangidwa ndi mankhwala, chomangiracho chiyenera kukhala chosagwirizana ndi zotsatira za mankhwala ndi matenthedwe pa kuviika ndi preforming kuti zitsimikizire mphamvu zokwanira panthawi yopanga;

(3) Kunyowa kwabwino;

(4) Kuchepa kwa fluff komanso mitu yochepa yosweka.

3. Polyester CHIKWANGWANI pamwamba mphasa

Polyester CHIKWANGWANI pamwamba anamva ndi mtundu watsopano kulimbikitsa CHIKWANGWANI mu makampani pultrusion.Pali chinthu chotchedwa Nexus ku United States, chomwe chimagwiritsidwa ntchito kwambiri muzinthu za pultruded kuti chilowe m'malogalasi CHIKWANGWANI pamwamba mphasa.Zili ndi zotsatira zabwino komanso zotsika mtengo.Zakhala zikugwiritsidwa ntchito bwino kwa zaka zoposa 10.

Ubwino wogwiritsa ntchito polyester fiber tissue mat:

(1) Itha kusintha kukana kwamphamvu, kukana kwa dzimbiri komanso kukana kukalamba kwachilengedwe;

(2) Ikhoza kupititsa patsogolo chikhalidwe cha mankhwala ndikupanga pamwamba pa mankhwalawo kukhala osalala;

(3) Kugwiritsa ntchito ndi mphamvu zolimba za polyester fiber pamwamba zimamveka bwino kuposa magalasi a C galasi, ndipo sizovuta kuthyola malekezero panthawi ya pultrusion, kuchepetsa ngozi za magalimoto;

(4) Kuthamanga kwa pultrusion kumatha kuwonjezeka;

(5) Ikhoza kuchepetsa kuvala kwa nkhungu ndikuwongolera moyo wautumiki wa nkhungu

4. Tepi ya nsalu ya galasi ya fiber

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 ntchito nsalu ziwiri-dimensional ndi nsalu zitatu-dimensional

Mawonekedwe ophatikizika azinthu zopangidwa ndi pultruded ndizosauka, ndipo kugwiritsa ntchito kuluka kwapawiri kumawonjezera mphamvu ndi kuuma kwa zinthu zopukutidwa.

Nsalu zopindika ndi zoluka za nsaluyi sizimalumikizana, koma zimalumikizana ndi nsalu ina, motero zimakhala zosiyana kwambiri ndi nsalu zamagalasi zachikhalidwe.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 la zinthu zakuthupi.Malingana ndi zofunikira zonyamula katundu, ulusi wolimbitsa thupi umakulungidwa mwachindunji mumpangidwe wokhala ndi mawonekedwe atatu, ndipo mawonekedwe ake ndi ofanana ndi omwe amapanga.Nsalu yanjira zitatu imagwiritsidwa ntchito munjira ya pultrusion kuti igonjetse 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.
