Chipangizo cholimbitsa ndi fupa lothandizira la chinthu cha FRP, chomwe chimatsimikizira momwe makina amagwirira ntchito. Kugwiritsa ntchito chinthu cholimbitsa kumakhudzanso kuchepetsa kuchepa kwa chinthucho ndikuwonjezera kutentha kwa kutentha komanso mphamvu yochepa ya kutentha.

Pakupanga zinthu za FRP, kusankha zinthu zolimbitsa kuyenera kuganizira mokwanira njira yopangira zinthuzo, chifukwa mtundu, njira yoyikira ndi kuchuluka kwa zinthu zolimbitsa zimakhudza kwambiri magwiridwe antchito a zinthu za FRP, ndipo kwenikweni zimatsimikiza mphamvu ya makina ndi modulus yotanuka ya zinthu za FRP. Magwiridwe antchito a zinthu zopukutidwa pogwiritsa ntchito zinthu zosiyanasiyana zolimbitsa ndi osiyana.

Kuphatikiza apo, pamene ikukwaniritsa zofunikira pakugwira ntchito kwa chinthucho, mtengo wake uyeneranso kuganiziridwa, ndipo zipangizo zolimbitsa zotsika mtengo ziyenera kusankhidwa momwe zingathere. Kawirikawiri, kusuntha kwa ulusi wagalasi kosasankhidwa kumakhala kotsika mtengo kuposa nsalu za ulusi; mtengo wakemphasa zagalasindi yotsika kuposa ya nsalu, ndipo kuzizira kwake kuli bwino. , koma mphamvu yake ndi yotsika; ulusi wa alkali ndi wotsika mtengo kuposa ulusi wopanda alkali, koma chifukwa cha kuchuluka kwa alkali, kukana kwake kwa alkali, kukana dzimbiri, komanso mphamvu zamagetsi zidzachepa.

Mitundu ya zinthu zolimbikitsira zomwe zimagwiritsidwa ntchito kwambiri ndi izi:

1. Kuyenda kwa ulusi wagalasi wosapindika

Pogwiritsa ntchito chida cholimbitsa kukula, chosapindikakuyendayenda kwa ulusi wagalasiZingagawidwe m'magulu atatu: silika wosaphika wopindidwa, wozungulira molunjika wosapindidwa ndi wozungulira wosapindidwa.

Chifukwa cha kusagwirizana kwa zingwe zolumikizidwa, zimakhala zosavuta kugwedezeka, zomwe zimapangitsa kuti chizungulire chosasunthika kumapeto kwa zida zolumikizira, zomwe zimakhudza kupita patsogolo kwa ntchito.

Kuyenda molunjika mosapotoka kuli ndi makhalidwe abwino monga kukulungika bwino, kulowa mwachangu kwa utomoni, komanso mphamvu zabwino kwambiri zamakanika azinthu, kotero ma mayendedwe ambiri osapotoka mwachindunji amagwiritsidwa ntchito pakadali pano.

Ma roving ozungulira ndi opindulitsa pakukweza mphamvu yopingasa ya zinthu, monga ma roving opindika ndi ma roving opangidwa ndi mpweya. Kuzungulira kwakukulu kumakhala ndi mphamvu yayikulu ya ulusi wautali wopitilira komanso kukula kwa ulusi waufupi. Ndi chinthu cholimba kutentha kwambiri, kutentha kochepa, kukana dzimbiri, mphamvu yayikulu komanso kusefa bwino. Ulusi wina umakulungidwa kukhala monofilament, kotero ukhozanso kukweza khalidwe la pamwamba pa zinthu zopindika. Pakadali pano, ma roving ozungulira akhala akugwiritsidwa ntchito kwambiri kunyumba ndi kunja, monga ulusi wopindika ndi weft wa nsalu zokongoletsera kapena zamakampani. Ingagwiritsidwe ntchito kupanga zinthu zokangana, zotetezera, zoteteza kapena zotsekera.

Zofunikira pakugwira ntchito kwa ulusi wagalasi wosapindika kuti ugwire ntchito:

(1) Palibe chochitika chopingasa;

(2) Kukanika kwa ulusi ndi kofanana;

(3) Kusonkhanitsa bwino;

(4) Kukana kuvala bwino;

(5) Pali mitu yochepa yosweka, ndipo sikophweka kuisintha;

(6) Kunyowa bwino komanso kulowetsedwa kwa utomoni mwachangu;

(7) Mphamvu yayikulu komanso kulimba.

Kupopera kwa Fiberglass poyenda mozungulira 

2. Mpando wagalasi wa fiber

Kuti zinthu za FRP zopangidwa ndi pultruded zikhale ndi mphamvu yokwanira yopingasa, zinthu zolimbitsa monga mphasa yodulidwa ya strand, mphasa yopingasa ya strand, mphasa yophatikizana, ndi nsalu ya ulusi wosapindika ziyenera kugwiritsidwa ntchito. Mpweya wopingasa wa strand ndi chimodzi mwa zinthu zolimbitsa zopingasa za ulusi wagalasi zomwe zimagwiritsidwa ntchito kwambiri pakadali pano. Pofuna kukonza mawonekedwe a zinthu,mphasa ya pamwambanthawi zina amagwiritsidwa ntchito.

Mpando wopitilira wa zingwe umapangidwa ndi zigawo zingapo za ulusi wagalasi wopitilira womwe umayikidwa mozungulira, ndipo ulusiwo umalumikizidwa ndi zomatira. Chovala cha pamwamba ndi chovala chopyapyala chonga pepala chomwe chimapangidwa mwa kuyika zingwe zodulidwazo mosiyanasiyana komanso mofanana kutalika kwake kokhazikika ndikulumikizidwa ndi guluu. Kuchuluka kwa ulusi ndi 5% mpaka 15%, ndipo makulidwe ake ndi 0.3 mpaka 0.4 mm. Chingapangitse pamwamba pa chinthucho kukhala posalala komanso kokongola, ndikuwonjezera kukana kwa ukalamba kwa chinthucho.

Makhalidwe a mphasa yagalasi ndi awa: kuphimba bwino, kosavuta kukhuta ndi utomoni, kuchuluka kwa guluu

Zofunikira pa njira yopukutira galasi la fiber mat:

(1) Ali ndi mphamvu zambiri zamakanika

(2) Pa mphasa zodulidwa ndi mankhwala, chomangiracho chiyenera kukhala cholimba ku zotsatira za mankhwala ndi kutentha panthawi yoviika ndi kukonza kuti chikhale ndi mphamvu zokwanira panthawi yopanga;

(3) Kunyowa bwino;

(4) Kuchepa kwa ntchafu komanso mitu yosweka yochepa.

Mpando wosokedwa ndi Fiberglass

Mpando wopangidwa ndi ulusi wagalasi

3. Mpando wa pamwamba wa ulusi wa polyester

Chovala chapamwamba cha ulusi wa polyester ndi mtundu watsopano wa zinthu zolimbitsa ulusi mumakampani opanga ma pultrusion. Pali chinthu chotchedwa Nexus ku United States, chomwe chimagwiritsidwa ntchito kwambiri pazinthu zopangidwa ndi ma pultruded kuti chilowe m'malo mwake.mphasa zagalasi za ulusi pamwambaIli ndi mphamvu zabwino komanso mtengo wotsika. Yagwiritsidwa ntchito bwino kwa zaka zoposa 10.

Ubwino wogwiritsa ntchito mphasa ya polyester fiber:

(1) Zingathandize kukana kukhudzana ndi zotsatira, kukana dzimbiri komanso kukana kukalamba kwa zinthu mumlengalenga;

(2) Zingathandize kuti pamwamba pa chinthucho pakhale bwino komanso kuti pamwamba pake pakhale posalala;

(3) Kugwiritsa ntchito ndi mphamvu zomangirira za nsalu yofewa ya polyester fiber pamwamba ndikwabwino kwambiri kuposa nsalu yofewa ya galasi C, ndipo sikophweka kuswa mbali zake panthawi ya pultrusion, zomwe zimachepetsa ngozi zoyimitsa magalimoto;

(4) Liwiro la pultrusion likhoza kuwonjezeka;

(5) Zingachepetse kuwonongeka kwa nkhungu ndikuwongolera moyo wa ntchito ya nkhungu

4. Tepi ya nsalu ya ulusi wagalasi

Mu zinthu zina zapadera zopangidwa ndi pultruded, kuti zikwaniritse zofunikira zina zapadera, nsalu yagalasi yokhala ndi m'lifupi wokhazikika komanso makulidwe osakwana 0.2mm imagwiritsidwa ntchito, ndipo mphamvu yake yokoka komanso mphamvu yake yopingasa ndi zabwino kwambiri.

5. Kugwiritsa ntchito nsalu zamitundu iwiri ndi nsalu zamitundu itatu

Kapangidwe ka makina opingasa a zinthu zopangidwa ndi pultruded composite ndi koipa, ndipo kugwiritsa ntchito kuluka mbali zonse ziwiri kumawonjezera mphamvu ndi kuuma kwa zinthu zopangidwa ndi pultruded.

Ulusi wopota ndi wopota wa nsalu yolukidwayi sulumikizana, koma umalumikizana ndi nsalu ina yolukidwa, kotero ndi wosiyana kwambiri ndi nsalu yagalasi yachikhalidwe. Ulusi womwe uli mbali iliyonse uli mu mkhalidwe wa collimated ndipo supanga kupindika kulikonse, motero mphamvu ndi kuuma kwa chinthu chopunduka, ndi wapamwamba kwambiri kuposa wa chinthu chopangidwa ndi continuous felt.

Pakadali pano, ukadaulo woluka mbali zitatu wakhala gawo lokongola komanso logwira ntchito kwambiri pakupanga ukadaulo mumakampani opanga zinthu zophatikizika. Malinga ndi zofunikira pakunyamula, ulusi wolimbitsa umalukidwa mwachindunji mu kapangidwe kake ka magawo atatu, ndipo mawonekedwe ake ndi ofanana ndi a chinthu chophatikizika chomwe chimapanga. Nsalu ya mbali zitatu imagwiritsidwa ntchito popangira pultrusion kuti igonjetse kudulidwa kwapakati kwa zinthu zachikhalidwe zolimbitsa ulusi. Ili ndi zovuta za kulimba kochepa komanso kudulidwa kosavuta, ndipo magwiridwe ake olumikizirana ndi abwino kwambiri.
