Mat ya Fiberglass vs. Wolukidwa Roving: Ndi Kulimbitsa Kotani Kumene Kuli Kwabwino Kwambiri Pomanga Mabwato?

Lowani mu sitolo iliyonse yogulitsa zinthu za m'madzi ndikufunsani kuti “fiberglass,"Ndipo mudzayang'anizana mopanda kanthu kenako ndi funso: fiberglassmphasa kapenawolukidwakuyendayendaAnthu ambiri omwe akumanga kapena kukonza bwato koyamba sadziwa kuti pali njira yoti asankhe. Amangogula chilichonse chomwe munthu amene ali kumbuyo kwa kauntala wawapatsa, ndipo nthawi zina zimenezo zimayenda bwino, ndipo nthawi zina sizimayenda bwino.

Mpando wodulidwa wa chingwendikuyendayenda kolukidwa Ndi nsalu ziwiri zomwe mungakumane nazo kwambiri pantchito yokonza bwato ndi manja. Komabe, sizili mpikisano kwenikweni—zimagwiritsiridwa ntchito pamodzi, m'malo enaake, pazifukwa zinazake. Kuzisakaniza, kapena kulumpha chimodzi chonse, ndi njira yodziwika bwino yomwe anthu amathera ndi thupi lomwe limawoneka bwino kwa chaka chimodzi kapena ziwiri kenako nkuyamba kuwonetsa zosindikizidwa kapena, choipa kwambiri, delaminates.

Apa ndi pomwe zimawasiyanitsa.

Mat odulidwa a Strand

Mpando wodulidwa wa chingweNdi zingwe zazifupi zagalasi, zazitali inchi imodzi kapena ziwiri, zomwazikana mbali zosiyanasiyana ndipo zogwiridwa pamodzi ndi chomangira—kaya chomangira ufa kapena chomangira emulsion. Sizili zofunika kwambiri pa ntchito zathu kupatula kuti zimafunika utomoni wopangidwa ndi styrene (polyester kapenaviniluester) kuti isungunuke bwino. Izi zimakhumudwitsa anthu kuposa momwe mungaganizire. Epoxy simaphwanya chomangiracho mwanjira yomweyo, kotero ngati muyesa kuyika mphasa ndi epoxy, mutha kukhala ndi chisokonezo cholimba, chonyowa pang'ono chomwe sichimalumikizana bwino.

Amapangidwa mwa kudula ulusi wagalasi wopitilira ndikuuponya pa lamba pomwe chomangira chimakhazikitsa mawonekedwe osasinthika. Palibe njira yolunjika, palibe kuluka - ulusi wobalalika paliponse. Nthawi zambiri mumaziwona mu 1.5 oz, 2 oz, kapena 3 oz pa sikweya mita, ndipo 1.5 oz ndi yomwe anthu ambiri amagwiritsa ntchito akamagwira ntchito yomanga.

Chinthu chokhudza mphasa ndichakuti imamwa utomoni. Yambiri. Mukuyang'ana china chake ngati chiŵerengero cha galasi-ndi-resin cha 25/75, zomwe zikutanthauza kuti laminate yomalizidwayo ndi yolemera kuposa momwe mungaganizire pa kuchuluka kwa galasi lomwe lilimo. Zimenezo zikumveka zoipa, ndipo pa mphamvu yeniyeni-pa paundi, zimakhala choncho. Koma chinthu chomwecho ndi chomwe chimapangitsamphasa yodulidwaIli ndi luso pa ntchito zake—imagwirizana ndi ma curve ndi ngodya zolimba zomwe nsalu yolimba yolukidwa ingangodutsamo, ndipo imadzaza mawonekedwe ozungulira kuti isasindikizidwe mu gelcoat yanu.

Kusoka Kozungulira

Zinthu zosiyana kotheratu. M'malo mwa zingwe zodulidwa mwachisawawa,kuyendayenda kolukidwandi mitolo yopangidwa ndi ulusi wagalasi yopitilira yomwe imalukidwa mu nsalu—yolukidwa bwino, madigiri 0 ndi 90, ngati chiguduli koma chopangidwa ndi galasi. Mutha kumva kukoka kulikonse ndi zala zanu.

Zolemera nthawi zambiri zimakhala ma oz 18 mpaka 24 pa sikweyadi iliyonse. Zinthu zolemera kwambiri — za ma oz 24 — zimawonekera pansi pa chipolopolo ndi kulikonse komwe kungafunike mphamvu yeniyeni kapena kukhudzidwa ndi kapangidwe kake.

Popeza ulusi umayenda mosalekeza m'malo modulidwa ndi kufalikira, kuyenda mozungulira kumakhala kolimba kwambiri pa paundi imodzi kuposa mphasa. Imafunanso utomoni wochepa kuti inyowetse bwino, pafupi ndi 50/50 glass-to-resin, kotero mumakhala ndi laminate yopepuka komanso yolimba ya galasi lofanana. Chovuta ndichakuti sikufuna kupindika mozungulira ma curve olimba - kuyikankhira pakona yakuthwa, ndipo imalumikiza, ndikusiya malo opanda kanthu pansi pake omwe simudzawawona mpaka jekete la gel litasweka patatha zaka zambiri. Imasiyanso mawonekedwe owoneka bwino ngati mutayiyika pansi pa finish coat, ndichifukwa chake simukutero.

Ndiye Ndi Liti Limene Lili Bwino Kwambiri?

Ayi, ndipo si yankho lolondola. Funsani womanga aliyense amene wayika mahatchi oposa awiri, ndipo adzakuuzani chinthu chomwecho: mumagwiritsa ntchito zonse ziwiri, mosinthana, chifukwa zikugwira ntchito zosiyanasiyana.

Fiberglass rkuyendaamanyamula katundu.Fiberglass matKumalumikiza zigawo pamodzi ndikukupatsani malo osalala pamene kuli kofunikira. Dulani mphasa pakati pa zigawo zoyendayenda kuti musunge nthawi kapena zinthu, ndipo mukudziika nokha pamavuto apakati pa msewu—zigawo sizimalumikizana popanda china chake chodzaza mipata pakati pa ulusi wopota.

Ndondomeko yodziwika bwino yotsutsana ndi gelcoat imakhala motere: choyamba mphasa (imasiya kusindikiza), kenako kuyendayenda, kenako mphasa kachiwiri, kusinthana kangapo momwe layup imafunira. Gawo loyamba nthawi zonse limakhala lofanana, mosasamala kanthu za china chilichonse chomwe mukugwiritsa ntchito, chifukwa kuyenda molunjika motsutsana ndi gelcoat nthawi zambiri kumadutsa pamapeto pake.

Kumene Chilichonse Chimagwiritsidwa Ntchito

Gmphasa za ulusi wa lass Ndi chisankho chanu pa chilichonse chokhala ndi ma tight curves—ma stringers, ndi ma transom corners—chifukwa zimatambasuka ndi kung'ambika ndi manja ndipo zimafanana popanda kulimbana. Ndi zomwe mumapezanso pa malo okonza ang'onoang'ono komwe simukusowa mphamvu zambiri, koma kungofuna chigwirizano chabwino komanso kumaliza kosalala.

Galasi la fiber rkuyendaZimapita kumene kapangidwe kake kali kofunika: pansi pa chivundikiro, ma transoms, ma bulkheads, ndi kulikonse komwe kungagwedezeke kapena kukhudza. Ngati mutakhala ndi roving yokha popanda mphasa, mungakhale ndi laminate yolimba koma ili ndi malo ofooka pakati pa zigawo, komanso mawonekedwe owoneka bwino a ulusi kulikonse pafupi ndi pamwamba. Si kuphatikiza kwabwino.

Njira Zingapo Zomwe Anthu Amalakwitsa Izi

Kugwiritsa ntchitoepoxyNdi mphasa yomwe imamangidwa ndi utomoni wa polyester mwina ndi cholakwika chofala kwambiri chomwe ndimachiwona—chomangira sichisungunuka momwe chiyenera kukhalira, ndipo mumapeza laminate yomwe imawoneka bwino mpaka itasungunuka.

Kudumpha mphasa ya fiberglass pakati pa zigawo zozungulira ndi chinthu china chachikulu, chomwe nthawi zambiri chimachitidwa kuti chisunge nthawi yokonza. Chingagwire bwino ntchito kwa kanthawi. Ichi ndi chimodzi mwa zifukwa zomwe zimachititsa kuti ma shells akale okonzedwa ayambe kusweka.

Ndipo palinso kusankha kulemera kwa nsalu kutengera chilichonse chomwe chili pashelefu osati zomwe gawo lenilenilo likufuna. Pansi pa thupi ndi pamwamba pa kabati si ntchito yofanana. Kuzisamalira mofanana kumawononga kulemera komwe simukukufuna kapena kumawononga komwe mukuchita.

Mayankho Achangu a Mafunso Ofala

Iskuyendayenda kolukidwaKodi ndi wamphamvu kuposa mphasa? Pa paundi imodzi, inde, ndi malire abwino—ulusi wopitirira umanyamula katundu bwino kuposa ulusi wodulidwa wobalalika. Mphasa siilipo kuti ikhale yolimba; ilipo kuti igwirizane ndi kukongola kwa pamwamba.

Kodi mungadumphe mphasa ndi kungogwiritsa ntchito roving? Mukhoza, koma imayambitsa mavuto pa chilichonse chomwe chimapangidwa. Popanda mphasa pakati pa zigawo, mumataya mphamvu ya interlaminar, ndipo mwina mudzawona mawonekedwe a ulusi akuwonekera pamapeto pake.

Kodi njira yoyenera yokonzera thupi la munthu ndi iti? Ikani mphasa pamwamba, kuyendayenda kuti mupeze mphamvu; yikanso mphasa ngati mukufuna kuikonza. Nthawi yeniyeni imadalira kukula ndi malo a chinthu chomwe mukukonza—palibe yankho limodzi lolondola lomwe limakhudza kukonza kulikonse.

Mfundo yofunika: izi sizili choncho ngakhale kuti funsoli nthawi zambiri limafunsidwa. Mpando wa fiberglass ndi kuluka koluka kumathetsa mavuto osiyanasiyana, ndipo ntchito zambiri zogwirira ntchito m'bwato zolimba zimagwiritsa ntchito zonse ziwiri, motsatira dongosolo loyenera, m'malo oyenera. Sankhani wopambana, ndipo pamapeto pake mudzakhala ndi laminate yomwe ndi yolemera kwambiri komanso yofooka kapena yolimba koma yodzaza ndi zofooka zobisika. Gwiritsani ntchito momwe ziyenera kugwiritsidwira ntchito, ndipo simuyenera kusankha konse.
