Nsalu ya Checkered ndi yosapindika, ndiyofunikira pamanja - paste FRP.Mphamvu ya gingham imakhala makamaka mu njira ya warp ndi weft ya nsalu.Pazochitika zomwe zimafuna mphamvu zambiri zokhotakhota kapena zokhotakhota, zimathanso kulukidwa kukhala gingham yanjira imodzi, yomwe imatha kukonzedwa mu warp kapena weft mopindika kwambiri.
Zofunikira zamtundu wa gingerbread ndi motere: ①Nsaluyo ndi yofanana, m'mphepete mwake ndi yowongoka, pamwamba pake ndi yathyathyathya komanso yopindika, ndipo palibe banga, fuzz, crease kapena makwinya;② Kachulukidwe ka mikwingwirima ndi ma weft, kulemera kwa dera, m'lifupi mwa nsalu ndi kutalika kwa mpukutu zimakwaniritsa muyezo;③ Kupiringa pa olimba pepala pachimake, zokhotakhota bwino;④ Kuthamanga kwa utomoni wofulumira komanso wabwino;⑤ Mphamvu yowuma ndi yonyowa yamagetsi opangidwa ndi nsalu ayenera kukwaniritsa zofunikira.
Makhalidwe a gulu lokutidwa ndi plaid nsalu ndi otsika interlaminar kukameta ubweya mphamvu ndi osauka compressive ndi kutopa mphamvu.
Fiberglass pepala anamva
(1) Dulani ulusi wonyezimira: dulani ulusi wagalasi (nthawi zina popanda kupotoza) muutali wa 50mm, kufalitsa mwachisawawa koma mofanana pa lamba wa mauna, kenaka gwiritsani ntchito emulsion binder kapena kuwaza ufa, kuchiritsa kutentha ndi kumanga ulusi wodulidwa. .Kudulidwa kumagwiritsidwa ntchito makamaka mu phala lamanja, kupanga mbale mosalekeza ndi kukanikiza kufa ndi njira ya SMC.Zofunikira za ulusi wodulidwa zimamveka motere: ① khalidwe la dera limakhala lofanana m'lifupi;②Ulusi wodulidwawo unagawidwa mofanana pamalo omveka, palibe mabowo aakulu omwe anapangidwa, ndipo chomangiracho chinagawidwa mofanana.③ zolimbitsa youma anamva mphamvu;④ Kulowetsa bwino kwa utomoni ndi kulowa.
(2) Kumveka kosalekeza kwaiwisi: silika yaiwisi yagalasi yopangidwa pojambula kapena silika yaiwisi yosalekeza yotengedwa mu chubu ya silika yaiwisi imayalidwa pa lamba wa mauna osasunthika m’chithunzi 8, ndipo chomangira cha ufa chimamata pamodzi.Ulusi wa fiberglass mat wopitilira umapitilira, kotero kulimbikitsa kwake pazinthu zophatikizika ndikwabwino kuposa kudulidwa kwa fiberglass mat.Amagwiritsidwa ntchito kwambiri popanga pultruding, RTM, chikwama choponderezedwa ndi magalasi owoneka ngati mapulasitiki otenthetsera (GMT).
(3) Pamwamba: Zogulitsa za FRP nthawi zambiri zimafunikira kupanga wosanjikiza wolemera wa utomoni, womwe nthawi zambiri umatheka ndi magalasi apakatikati amchere.Chifukwa kumverera kwamtunduwu kumapangidwa ndi galasi lapakati lamchere (C), kumapereka kukana kwa mankhwala a FRP, makamaka kukana asidi.Nthawi yomweyo, chifukwa chomverera ndi chochepa thupi komanso kukula kwa ulusi wagalasi ndi kakang'ono, kumathanso kuyamwa utomoni wochulukirapo kuti mupange utomoni wolemera, womwe umakwirira njere ya zinthu zolimba zamagalasi (monga plaid plaid), ndikusewera udindo wa kusinthidwa pamwamba.
(4) Kumverera kofunikira: kumveka kwa singano kapena kugawanika kukhala ulusi waufupi womangika ndi silika wosalekeza wa silika.Zingwe zomangira zomangira zimapangidwa podula ulusi wagalasi ndikuzungulira mu zidutswa za 50mm ndikuziyika mwachisawawa pagawo lomwe limayikidwa kale pa lamba wotumizira.Kenako singano zokhala ndi mipiringidzo zimagwiritsidwa ntchito kubala ulusi woyambira mu gawo lapansi, pomwe crochet imamangirira ulusi wina kuti apange mawonekedwe atatu.Zomwe zili m'munsi zimatha kukhala ulusi wagalasi kapena ulusi wina wopyapyala, singano yamtunduwu imakhala ndi kumverera kosamveka.Ntchito zake zazikuluzikulu zimaphatikizapo zinthu zotchinjiriza kutentha, zida zopangira kutentha, zosefera, komanso zitha kugwiritsidwa ntchito popanga FRP, koma mphamvu ya FRP ndiyotsika, kuchuluka kwa ntchito kumakhala kochepa.Mtundu wina wosalekeza wa ulusi wofunikira womwe umasokera umamveka ndi mawonekedwe amitundu itatu omwe amamveka momwe magalasi osalekeza amaponyedwa mosalekeza pa lamba wa mauna osalekeza ndi chipangizo choponyera waya ndi singano ndi mbale ya singano.Mtundu woterewu umagwiritsidwa ntchito makamaka popanga magalasi opangidwa ndi magalasi opangidwa ndi thermoplastic stampable sheets.
(5) stitched anamva: kudula galasi CHIKWANGWANI kuchokera 50mm kapena ngakhale 60cm kutalika akhoza stitched ulusi odulidwa kapena CHIKWANGWANI yaitali anamva ndi kusoka makina.Yoyambayo imatha kulowa m'malo mwazomangira zomangira zomangika zomwe zimamveka m'magwiritsidwe angapo, ndipo zomaliza zimatha kulowa m'malo mwa ulusi waiwisi wosalekeza womwe umamveka pamlingo wina.Ubwino wawo wamba palibe binder, pewani kuipitsidwa kwa njira yopangira, nthawi yomweyo, kulowa bwino, ntchito yomanga, mtengo wotsika.
