Makhalidwe enieni a zinthu zopangidwa ndi ulusi amalamulidwa ndi ulusi. Izi zikutanthauza kuti pamene utomoni ndi ulusi ziphatikizidwa, makhalidwe awo amafanana kwambiri ndi a ulusi uliwonse. Deta yoyesera ikuwonetsa kuti zinthu zolimbikitsidwa ndi ulusi ndi zomwe zimanyamula katundu wambiri. Chifukwa chake, kusankha nsalu ndikofunikira kwambiri popanga nyumba zopangidwa ndi ulusi.
Yambani njirayi posankha mtundu wa zolimbitsa zomwe zikufunika pa ntchito yanu. Wopanga wamba angasankhe mitundu itatu yodziwika bwino ya zolimbitsa: ulusi wagalasi, ulusi wa kaboni ndi Kevlar® (ulusi wa aramid). Ulusi wagalasi nthawi zambiri umakhala chisankho chodziwika bwino, pomwe ulusi wa kaboni umapereka kuuma kwambiri komanso kukana kukwawa kwa Kevlar®. Kumbukirani kuti mitundu ya nsalu imatha kuphatikizidwa mu ma laminate kuti apange ma hybrid stacks omwe amapereka zabwino za zinthu zingapo.
Zolimbitsa Magalasi a Fiberglass
Fiberglass ndi chinthu chodziwika bwino. Fiberglass ndiye maziko a makampani opanga zinthu zosiyanasiyana. Yakhala ikugwiritsidwa ntchito m'mafakitale ambiri kuyambira m'ma 1950 ndipo mawonekedwe ake akumveka bwino. Fiberglass ndi yopepuka, ili ndi mphamvu yolimba komanso yopondereza, imatha kupirira kuwonongeka ndi kudzaza mozungulira, ndipo ndi yosavuta kugwiritsa ntchito. Zinthu zomwe zimachokera mukupanga zimadziwika kuti fiberglass reinforced plastic (FRP). Ndi yofala m'mbali zonse za moyo. Chifukwa chake imatchedwa fiberglass ndichifukwa chakuti mtundu uwu wa ulusi wa ulusi umapangidwa posungunula quartz ndi zinthu zina zamtengo wapatali kutentha kwambiri kukhala slurry yagalasi. Kenako imatulutsidwa ndi ulusi wothamanga kwambiri. Mtundu uwu wa ulusi umachokera ku kapangidwe kake ka mitundu yosiyanasiyana. Ubwino wake ndi kukana kutentha, kukana dzimbiri, mphamvu yayikulu. Kuteteza bwino. Ndipo ulusi wa kaboni uli ndi vuto lomwelo ndikuti chinthucho ndi chofooka kwambiri. Kusagwira bwino ntchito. Sizimatha kusweka. Pakadali pano, kutchinjiriza, kusunga kutentha, kukana dzimbiri mosavuta komanso minda ina yambiri imagwiritsa ntchito pulasitiki yolimbitsa ulusi wagalasi.
Fiberglass ndi yomwe imagwiritsidwa ntchito kwambiri pa zinthu zonse zomwe zilipo. Izi zimachitika makamaka chifukwa cha mtengo wake wotsika komanso mawonekedwe ake apakati. Fiberglass ndi yoyenera ntchito za tsiku ndi tsiku komanso zida zomwe sizifuna nsalu ya ulusi wofunikira kwambiri kuti ikhale yolimba komanso yolimba.
Kuti fiberglass ikhale ndi mphamvu zambiri, ingagwiritsidwe ntchito ndi ma epoxy resins ndipo imatha kuchiritsidwa pogwiritsa ntchito njira zodziwika bwino zoyeretsera. Ndi yoyenera kugwiritsidwa ntchito m'mafakitale a magalimoto, a m'madzi, omanga, a mankhwala ndi a ndege ndipo imagwiritsidwa ntchito kwambiri pazinthu zamasewera.

Kulimbitsa Ulusi wa Aramid
Ulusi wa Aramid ndi mankhwala apamwamba kwambiri. Uli ndi mphamvu zambiri, kukana kutentha kwambiri, kukana dzimbiri, kulemera kopepuka ndi zina, ndipo ndi chimodzi mwa zinthu zofunika kwambiri pamakampani oteteza. Pali zinthu zambiri zomwe zimagwiritsidwa ntchito pazida zoteteza zipolopolo, zida zowuluka.
Ulusi wa Aramid ndi umodzi mwa ulusi woyamba wopangidwa ndi mphamvu zambiri womwe walandiridwa mumakampani opanga mapulasitiki olimbikitsidwa ndi ulusi (FRP). Ulusi wa para-aramid wa mtundu wa Composite ndi wopepuka, uli ndi mphamvu yabwino kwambiri yogwirira ntchito, ndipo umaonedwa kuti ndi wolimba kwambiri ku kugunda ndi kusweka. Ntchito zodziwika bwino zimaphatikizapo ma shells opepuka monga kayaks ndi ma canoes, ma fuselage panels a ndege ndi zotengera zopanikizika, magolovesi osadulidwa, ma vests oteteza zipolopolo ndi zina zambiri. Ulusi wa Aramid umagwiritsidwa ntchito ndi ma epoxy kapena vinyl ester resins.

Kulimbitsa Ulusi wa Kaboni
Ndi mpweya wochuluka wa kaboni woposa 90%, ulusi wa kaboni uli ndi mphamvu yayikulu kwambiri yogwira ntchito mumakampani a FRP. Ndipotu, ulinso ndi mphamvu zazikulu kwambiri zokakamiza komanso zopindika mumakampaniwa. Pambuyo pokonza, ulusi uwu umaphatikizidwa kuti upange zolimbitsa ulusi wa kaboni monga nsalu ndi zokokera. Kulimbitsa ulusi wa kaboni kumapereka mphamvu yayikulu komanso kuuma kwapadera, ndipo nthawi zambiri kumakhala kokwera mtengo kuposa zolimbitsa ulusi zina.
Kuti ulusi wa kaboni ukhale wamphamvu kwambiri, uyenera kugwiritsidwa ntchito ndi ma epoxy resins ndipo ukhoza kuchiritsidwa pogwiritsa ntchito njira zodziwika bwino zoyeretsera. Ndi yoyenera kugwiritsidwa ntchito m'magalimoto, m'madzi ndi m'mlengalenga ndipo nthawi zambiri imagwiritsidwa ntchito m'zovala zamasewera.
