Poyang'anizana ndi vuto lalikulu la kuipitsidwa kwa chilengedwe, chidziwitso cha kuteteza chilengedwe cha anthu chawonjezeka pang'onopang'ono, ndipo kugwiritsa ntchito zinthu zachilengedwe kwakulanso. Ubweya wa zomera ndi wochezeka, wopepuka, wogwiritsa ntchito mphamvu zochepa komanso mawonekedwe obwezerezedwanso a ulusi wa zomera zakopa chidwi chachikulu. Zidzadziwika mtsogolomu. Padzakhala chitukuko chapamwamba. Komabe, ulusi wa zomera ndi chinthu chosiyana chokhala ndi kapangidwe ndi kapangidwe kovuta, ndipo pamwamba pake pali magulu a hydrophilic hydroxyl. Kugwirizana ndi matrix kumafuna chithandizo chapadera kuti zinthu za gululi ziwongolere. Ulusi wa zomera umagwiritsidwa ntchito pazinthu za gululi, koma zambiri mwa izo zimangokhala ulusi waufupi komanso ulusi wosapitirira. Makhalidwe abwino oyambirira sanagwiritsidwe ntchito mokwanira, ndipo amagwiritsidwa ntchito ngati zodzaza. Ngati tingathe kuyambitsa ukadaulo woluka, ndi yankho labwino. Ma preforms opangidwa ndi ulusi wa zomera angapereke njira zambiri zogwirira ntchito pazinthu za gululi, koma pakadali pano akugwiritsidwa ntchito pang'ono ndipo ndi oyenera kufufuza ndi kukulitsa. Ngati tingaganizirenso njira yachikhalidwe yogwiritsira ntchito ulusi, ndikuyambitsa malingaliro amakono aukadaulo wophatikizana kuti tiwongolere, tiwongolere ubwino wogwiritsa ntchito ndikuwongolere zofooka zake, zidzatha kupatsa ulusi wa zomera phindu latsopano ndi ntchito zake.

Ulusi wa zomera nthawi zonse wakhala wosasiyana ndi moyo wa tsiku ndi tsiku wa anthu. Chifukwa cha makhalidwe ake abwino komanso osinthika, ulusi wa zomera wakhala chinthu chofunikira kwambiri pa moyo wa anthu. Komabe, chifukwa cha kupita patsogolo kwa ukadaulo komanso kukwera kwa makampani opanga mafuta, ulusi ndi mapulasitiki opangidwa ndi anthu pang'onopang'ono asintha ulusi wa zomera kukhala zinthu zofunika kwambiri chifukwa cha ubwino wa ukadaulo wopanga zinthu wopangidwa bwino kwambiri, kusiyanasiyana kwa zinthu komanso kulimba bwino. Komabe, mafuta si chuma chosinthika, ndipo mavuto otaya zinyalala omwe amayamba chifukwa cha kutaya zinthu zotere komanso kuchuluka kwa mpweya woipa womwe umatulutsa panthawi yopanga zinthu zapangitsa anthu kuganiziranso momwe zinthuzo zingagwiritsidwire ntchito. Pogwiritsa ntchito njira yoteteza chilengedwe komanso kukhazikika, ulusi wachilengedwe wa zomera wabwereranso kutchuka. M'zaka zaposachedwa, zinthu zopangidwa ndi ulusi wa zomera monga zinthu zolimbitsa thupi zayamba kutchuka.

Ulusi wa zomera ndi zosakaniza

Kapangidwe kake kakhoza kupangidwa ndi njira yopangira. Ulusi wokulungidwa ndi matrix umapereka mawonekedwe athunthu komanso enieni a chinthucho, ndipo umateteza ulusi kuti usawonongeke chifukwa cha zinthu zachilengedwe, komanso umagwira ntchito ngati mlatho wotumizira kupsinjika pakati pa ulusi; pomwe ulusiwo umanyamula mphamvu zambiri zakunja ndi mphamvu zake zabwino kwambiri zamakanika ndipo umatha kudutsa. Kapangidwe kake kamagwira ntchito zosiyanasiyana. Chifukwa cha kukhuthala kwake kochepa komanso mphamvu zake zambiri, ulusi wa zomera ukhoza kusintha mphamvu zamakanika ndikusunga kukhuthala kochepa ukapangidwa kukhala ma FRP composites. Kuphatikiza apo, ulusi wa zomera nthawi zambiri umakhala ma cell a zomera, ndipo mabowo ndi mipata mkati mwake zimatha kubweretsa mphamvu zabwino kwambiri zotetezera kutentha ku chinthucho. Polimbana ndi mphamvu zakunja (monga kugwedezeka), umapindulanso ndi porosity yake, zomwe zimathandiza kuti mphamvuyo itha kutha msanga. Kuphatikiza apo, njira yonse yopangira ulusi wa zomera imatulutsa kuipitsa pang'ono ndipo imagwiritsa ntchito mankhwala ochepa, imakhala ndi kutentha kochepa, ili ndi ubwino wogwiritsa ntchito mphamvu zochepa, ndipo kuchuluka kwa kuwonongeka kwa makina panthawi yokonza nakonso kumakhala kochepa; kuphatikiza apo, ulusi wa zomera ndi mawonekedwe achilengedwe Obwezerezedwanso, kupanga kosatha kumatha kuchitika pansi pa kuyang'aniridwa koyenera ndi kuwongolera. Mothandizidwa ndi ukadaulo wamakono, kuwonongeka kwa zinthu ndi kukana kwa nyengo kwa zinthu zayang'aniridwa bwino, kotero kuti zitha kuwola pambuyo pa moyo wa chinthucho, popanda kuwononga zinyalala, ndipo mpweya wotuluka chifukwa cha kuwola umachokeranso ku kukula koyamba. Gwero la mpweya mumlengalenga likhoza kukhala lopanda mpweya.
