Mat Yodulidwa ndi Nsalu Yozungulira (ndi Mat Yophatikiza): Momwe Mungamangire Laminate Yanu

CSM imayamba ngati galasi lopitirira lomwe limadulidwa kukhala ulusi waufupi — nthawi zambiri 25–50 mm — ndikuyikidwa ngati ukonde wosasinthika, kenako n’kulumikizidwa ndi cholumikizira cha polyester chopangidwa ndi ufa kapena emulsion chomwe chimasungunuka mu utomoni panthawi youmba. Popeza palibe ulusi womwe umadutsa m’mbali, mphamvu imafalikira mofanana mbali zonse, ndipo pepalalo limagwirizana ndi ma curve ophatikizika omwe nsalu yolukidwa ingalumikize kapena kukweza. Limanyowa mosavuta, limalumikizana bwino pakati pa zigawo zolimba, ndipo limagwirizana ndi polyester, vinyl ester ndi epoxy resin systems pamanja oyika, kupopera ndi kulowetsedwa.

Kapangidwe komweko kosasinthika ndi kosiyana. Ukonde wofewa umasunga utomoni wambiri kuposa kapangidwe kolukidwa, kotero kugwiritsa ntchito utomoni pa milimita yomalizidwa kumakhala kokwera ndipo mphamvu yeniyeni ndi yotsika kuposa ulusi wopitilira - nkhani yoyerekeza utomoni moona mtima, osati chilema. CSM ndi yabwino kwambiri pomwe zabwino zake ndizofunikira: zigawo zosungira za gel-coat, zotchingira dzimbiri, mawonekedwe ovuta, ndi kulumikizana pakati pa ma plies olukidwa.

Zipangizo zitatu, patebulo limodzi

Funsani kuti ndi iti yolimba - mphasa yodulidwa kapena yolukidwa - ndipo mumapeza yankho lodalirika kuchokera ku malo onse ogulitsa. Ilinso funso loyamba lolakwika. Laminate si mulu wa mapepala "olimba"; ndi gulu la zigawo, chilichonse chili ndi ntchito: kumanga makulidwe, kunyamula katundu mbali yodziwika, kulumikiza ma curve ovuta, kapena kuteteza pamwamba. Mukapereka ntchitozo, kusankha kwa zinthu nthawi zambiri kumadzipanga: nthawi zina ndi mphasa yodulidwa, nthawi zina yolukidwa, nthawi zambiri zonse zimasinthana, ndipo nthawi zina mphasa yosokedwa yomwe imagwira ntchito ziwiri nthawi imodzi.

Bukuli likuyerekeza mabanja atatu ofunikira momwe magulu opanga ndi ogula amawafotokozera — mwa kapangidwe kake, kachitidwe ka utomoni ndi njira zake — ndipo limagwiritsa ntchito deta yeniyeni yolemera m'malo mwa mitundu yonse. Limathera ndi chitsanzo chogwira ntchito ndi mndandanda wa RFQ womwe mungatumize mwachindunji kwa wogulitsa.

Mpando wodulidwa wa chingwe: chophimba, kukhazikika komanso makulidwe

Zonse zitatuzi ndi zolimbitsa ulusi wagalasi, koma kapangidwe kake kamasiyana m'njira zomwe zimasankha komwe chilichonse chiyenera kukhala mu laminate.

Zinthu ziwiri ndizofunikira kuziwerenga kuchokera patebulo limenelo. Choyamba, mphamvu yosweka imakwera masitepe oyera ndi kulemera — kuyambira ≥80 N pa 100 g/m² mpaka ≥200 N pa 900 g/m² — kotero "kulemera kwambiri" kuli ndi tanthauzo loyezeka, ndipo kutchula mphamvu yeniyeni m'malo mwa "mphasa yolemera" yosamveka bwino kumapangitsa kuti RFQ yanu ikhale yofanana ndi ogulitsa onse. Chachiwiri, kulekerera kumakhala kocheperako (±5% pa kulemera, ≤0.2% chinyezi): kuchuluka kwa chinyezi ndikofunikira chifukwa mphasa yonyowa sinyowa bwino ndipo imatha kutulutsa matuza ikagwiritsidwa ntchito, kotero ngati shopu yanu imasunga zinthuzo nthawi yachilimwe, funsani momwe mipukutu imakulungidwira komanso nthawi yayitali yomwe yatsegulidwa.

Kuluka kozungulira: mphamvu yolunjika

Kuluka kozungulira ndi nsalu yolemera kwambiri padziko lonse la FRP: mitolo ya ulusi wopitilira - mizere yomweyi yomwe imagwiritsidwa ntchito pozungulira ulusi, komwe miyeso yofanana ya tex imathamanga 2,400 mpaka 9,600 - yolumikizidwa mu nsalu yolimba, yokhotakhota. Chifukwa ulusi umayenda mosalekeza mozungulira pa warp ndi weft, katundu umayenda mosalekeza kudzera mu wosanjikiza, ndichifukwa chake kuluka kozungulira kumanyamula ntchito zomangira m'mabwato, matanki, mapanelo ndi ma profiles pomwe CSM imagwira ntchito zosinthira ndi ntchito yozungulira pamwamba pake.

Kuluka komweko kumafotokoza malire ake. Mapaketi olimba amakhala odzitamandira ndi pamwamba pake, kotero kusindikiza ndi chiopsezo chachikulu pazida zodzikongoletsera pokhapokha ngati mphasa kapena chophimba chikulekanitsa nsalu ndi mapeto ake. Ndipo pamakhota ophatikizika, nsaluyo imakana kukokedwa mbali ziwiri nthawi imodzi.

Matiketi ophatikizana ndi kusoka: ntchito ziwiri pa pass imodzi

Mpando wolukidwa wolumikizana umasoka wosanjikiza wolukidwa ndi wosanjikiza wodulidwa kukhala pepala limodzi; onjezerani chophimba pamwamba ndipo chimakhala mphanda wolumikizana wolumikizana. Mitundu ya Ruifiber imagwiritsa ntchito ulusi wosokera wa polyester m'malo mwa chomangira cha mankhwala, kotero pepalalo limanyowa mwachangu ndipo silinyamula chomangira kuti chisungunuke - njira imodzi yosungiramo zinthu imalowa m'malo mwa ziwiri, komwe kumachokera kufunika kwa ntchito.

M'lifupi mwachizolowezi ndi 1,250 mm ndi 1,270 mm, kukula kwake ndi kofanana ndi ntchito ya nkhungu ndi mapanelo. Kapangidwe kosokedwako kamasunga mphamvu yolunjika ya chozunguliracho komanso makulidwe ake ofulumira komanso kukwera kwa pamwamba pa chinthu chimodzi; Ruifiber imayika chophimba cha fiberglass cha ntchito zomwe zimafuna kuchedwa kwa moto komanso kukana kutentha kuposa chotchinga cha polyester. Ntchito zofalitsidwa zimaphatikizapo ma profiles opunduka, ndodo, machubu ndi mathireyi a chingwe; matanki osagwira dzimbiri, mapaipi ndi zotengera zopanikizika pogwiritsa ntchito filament winding; ndi chotchinga chotsekedwa ndi chotseguka - choyikidwa ndi manja, RTM ndi chotchinga chopondereza.

Kusinthana ndi kulamulira. Kuphatikiza kosokedwa kumakupatsirani chiŵerengero cha zolukidwa ndi zodulidwa zomwe fakitale imagwiritsa ntchito; ngati ndondomeko yanu ya laminate ikufunika kuikonza yokha - mwachitsanzo, kukwera kwa liner yowonjezera pamalo omwe pali dzimbiri - CSM yosiyana ndi ma plies osokedwa amakupatsirani kusintha kwabwino.
