Ulusi wa MpweyaChotengera Choponderezera Chophatikiza ndi choponderezera ndi khoma lopyapyala lokhala ndi chotchingira chotsekedwa bwino komanso chotchingira ulusi wamphamvu kwambiri, chomwe chimapangidwa makamaka ndi njira yokhotakhota ndi kuluka ulusi. Poyerekeza ndi zotengera zachitsulo zachikhalidwe, chotchingira cha zotengera zopanikiza chophatikiza chimagwira ntchito yosungira, kutseka ndi kuteteza dzimbiri la mankhwala, ndipo chotchingira chophatikiza chimagwiritsidwa ntchito makamaka kunyamula katundu wamkati. Chifukwa cha mphamvu yayikulu komanso kapangidwe kabwino ka zophatikiza, zotengera zopanikiza zophatikizana sizinangowonjezera mphamvu yawo yonyamula katundu, komanso zachepetsa kwambiri kulemera kwa zotengera poyerekeza ndi zotengera zachitsulo zachikhalidwe.
Chigawo chamkati cha chotengera chopanikizika ndi ulusi ndi kapangidwe ka liner, komwe ntchito yake yayikulu ndikugwira ntchito ngati chotchinga chotseka kuti mpweya wopanikizika kwambiri kapena zakumwa zomwe zimasungidwa mkati zisatuluke, komanso nthawi yomweyo kuteteza gawo lakunja la ulusi. Chigawochi sichidzawonongeka ndi zinthu zomwe zasungidwa mkati ndipo gawo lakunja ndi gawo la ulusi lolimbikitsidwa ndi resin matrix, lomwe limagwiritsidwa ntchito kwambiri kupirira katundu wambiri wopanikizika mu chotengera chopanikizika.
1. Kapangidwe ka mitsempha yamagazi yoponderezedwa ndi ulusi
Pali mitundu inayi ikuluikulu ya zombo zopanikiza zophatikizana: zozungulira, zozungulira, zozungulira ndi zozungulira. Chombo chozungulira chimakhala ndi gawo la silinda ndi mitu iwiri. Zombo zopanikiza zachitsulo zimapangidwa m'mawonekedwe osavuta okhala ndi mphamvu zochulukirapo mbali ya axial. Zombo zozungulira zimakhala ndi kupsinjika kofanana mbali ya wopingasa ndi weft pansi pa kupsinjika kwamkati ndipo ndi theka la kupsinjika kozungulira kwa zombo zozungulira. Mphamvu ya zinthu zachitsulo ndi yofanana mbali zonse, kotero chombo chozungulira chopangidwa ndi chitsulo chapangidwa kuti chikhale ndi mphamvu yofanana, ndipo chimakhala ndi kulemera kocheperako pamene voliyumu ndi kupanikizika zili zotsimikizika. Mphamvu ya chidebe chozungulira ndiyo yabwino kwambiri, khoma la chidebe lingapangidwenso kukhala lopyapyala kwambiri. Komabe, chifukwa cha zovuta kwambiri popanga zombo zozungulira, nthawi zambiri zimagwiritsidwa ntchito mu zombo zamlengalenga ndi zochitika zina zapadera. Chombo chozungulira popanga mafakitale chimakhala chosowa kwambiri, koma nthawi zina kapena pakufunika kapangidwe kameneka, mwachitsanzo, magalimoto amlengalenga kuti agwiritse ntchito mokwanira malo ochepa, adzagwiritsa ntchito kapangidwe kapadera aka. Chidebe chozungulira chimafunika makamaka pamene malo ali ochepa, kugwiritsa ntchito bwino malo ndi kugwiritsa ntchito nyumba, monga magalimoto ang'onoang'ono a thanki, magalimoto a sitima, ndi zina zotero, zidebe zotere nthawi zambiri zimakhala zotengera zotsika kapena zotengera zopanikizika mumlengalenga ndipo zofunikira za chowunikira zimakhala bwino.
Kuvuta kwa kapangidwe kazopangidwa ndi zinthu zosiyanasiyanachotengera cha kupanikizika chokha, kusintha kwadzidzidzi kwa makulidwe a mutu ndi mutu, makulidwe osinthasintha ndi ngodya ya mutu, ndi zina zotero, kumabweretsa zovuta zambiri pakupanga, kusanthula, kuwerengera ndi kupanga. Nthawi zina, zotengera za kupanikizika kophatikizana sizimangofunika kukulungidwa pamakona osiyanasiyana ndi ma ratio osinthasintha a liwiro m'gawo la mutu, komanso zimafunika kugwiritsa ntchito njira zosiyanasiyana zozungulira malinga ndi kapangidwe kake. Nthawi yomweyo, mphamvu ya zinthu zothandiza monga friction coefficient iyenera kuganiziridwa. Chifukwa chake, kapangidwe koyenera komanso koyenera kokha ndi komwe kungatsogolere bwino njira yopangira zozungulira za zotengera za kupanikizika kophatikizana, kuti apange zinthu zopepuka za zotengera za kupanikizika kophatikizana zomwe zimakwaniritsa zofunikira pa kapangidwe kake.
2. Zipangizo za chotengera chopanikizika ndi ulusi
Monga gawo lalikulu lonyamula katundu, gawo lozungulira ulusi liyenera kukhala ndi mphamvu zambiri, modulus yapamwamba, kuchepa kwa kachulukidwe, kukhazikika kwa kutentha komanso kunyowa bwino kwa utomoni, komanso kusinthasintha kwabwino kwa kuzunguliza komanso kulimba kwa ulusi wofanana. Ulusi wolimbitsa womwe umagwiritsidwa ntchito kwambiri pazitseko zopepuka zophatikizira ndi mongaulusi wa kaboni, ulusi wa PBO,ulusi wa polyamine wonunkhira, ndi ulusi wa UHMWPE.
