nkhani

Mu dziko la kupanga ndi kukonza zinthu zosiyanasiyana, "kulimbitsa" ndiye maziko a kapangidwe kanu. Kaya mukumanga chombo cha m'madzi, kukonza gulu la magalimoto, kapena kupanga matanki amafakitale, kusankha yoyenera.Mitundu ya mphasa za fiberglassndi kusiyana pakati pa gawo logwira ntchito bwino ndi kulephera kwa kapangidwe kake.

Kuchokera pa chindapusaminofu ya pamwamba pa fiberglassamagwiritsidwa ntchito pokongoletsa zinthu zokongola komanso zolemeraMpando wa fiberglass wa 1708Bukuli limagwiritsidwa ntchito popanga ma laminate, ndipo limafotokoza zonse zomwe muyenera kudziwa zokhudza ma fiberglass reinforcements amakono.

1. Chopped Strand Mat (CSM): Kavalo Wogwira Ntchito M'makampani

Mpando wodulidwa wa chingwe(CSM)Ndi njira yodziwika kwambiri yolimbikitsira yomwe imagwiritsidwa ntchito popanga "chophimba chotseguka". Imakhala ndi ulusi waufupi wagalasi (nthawi zambiri umakhala mainchesi 1 mpaka 2) woyikidwa mwachisawawa ndikugwirizanitsidwa pamodzi ndi chomangira cha mankhwala.

Zomangira za Emulsion vs. Powder

Chimodzi mwa zinthu zofunika kwambiri pa nkhaniyimphasa yodulidwa ndi galasindi mtundu wa binder:

Emulsion ya mphasa yodulidwa ndi fiberglass:Izi zimagwiritsa ntchito chomangira chopangidwa ndi madzi chomwe chimasweka mwachangu mu ma polyester ndi ma vinylester resins. Chimasinthasintha komanso chosavuta kuchiyika pamwamba pa ma curve ovuta.

Chomangira ufa:Kawirikawiri amagwiritsidwa ntchito m'mafakitale enaake pomwe kukana mankhwala ndikofunikira kapena pogwira ntchito ndi ma resin enaake apadera.

Zolemera ndi Kukula Kofanana

CSM nthawi zambiri imagawidwa m'magulu malinga ndi kulemera. Ku US,Mpando wa fiberglass wa 1.5 oz(1.5 ounces pa sikweya mita) ndiye muyezo wagolide wokonzanso zinthu zonse. Padziko lonse lapansi, izi nthawi zambiri zimatchedwa ndi metric equivalent,mphasa ya csm 450 fiberglass(450 magalamu pa mita imodzi).

CSM 300 (1 oz):Zabwino kwambiri pa laminate yopyapyala kapena ngati gawo losinthira.

CSM 450 (1.5 oz):Kulemera kosiyanasiyana kwambiri pomanga bwato ndi kugwiritsa ntchito mphasa za nsalu za fiberglass.

600g Fiberglass Matting:Njira yolemetsa yopangira makulidwe mwachangu.

2. Kukwaniritsa Mapeto Abwino Kwambiri: Fiberglass Surface Mat & Tissue

Ngati munaonapo “chitsanzo” cha ulusi wagalasi chikuonekera kudzera mu gelcoat yomalizidwa, mwaonapo “kusindikizidwa.” Pofuna kupewa izi, akatswiri amagwiritsa ntchitomphasa ya pamwamba pa fiberglass(yomwe imadziwikanso kutiminofu ya pamwamba pa fiberglasskapenamphasa yophimba ndi fiberglass).

Nsalu iyi ndi yopyapyala kwambiri komanso yopepuka. Imagwira ntchito ngati chotchinga pakati pa kulimbitsa kapangidwe kake ndi jeli pamwamba pake. Pogwiritsa ntchitomphasa ya fiberglass tissue, mumapanga pamwamba podzaza ndi utomoni womwe:

Zimakonza kapangidwe ka pansithonje lodulidwa.

Amapereka utoto wabwino kwambiri komanso wokonzeka kupenta.

Zimawonjezera kukana kwa dzimbiri kwa laminate.

3. Nyumba Zamphamvu Zomanga: 1708 ndi Zosokera

Ngati chiŵerengero cha mphamvu ndi kulemera ndicho chofunika kwambiri, CSM yokhazikika sikokwanira. Apa ndi pamenemphasa yosokera ya fiberglassndipo zinthu za biaxial zimayamba kugwira ntchito.

TheMpando wa fiberglass wa 1708ndi nsalu yosakanikirana yaukadaulo. Ili ndi nsalu ya biaxial ya 17 oz (ulusi womwe umayenda pa +45° ndi -45°) yosokedwa ku 0.75 ozmphasa yodulidwa ya ulusi.

N’chifukwa chiyani muzigwiritsa ntchito?Ulusi wa biaxial umapereka mphamvu yayikulu yomanga, pomwe wosanjikiza wa matte womwe umalumikizidwa umatsimikizira kuti umagwirizana kwambiri ndi wosanjikiza wakale wa laminate.

Mapulogalamu:Kukonza zingwe zomangira, kusintha transom, ndi kumanga chidebe champhamvu kwambiri.

4. Funso Lofunika Kwambiri: Kodi ndi Epoxy Fiberglass Mat?

Chinthu chofala chomwe chimasokoneza anthu odzipangira okha zinthu ndi akatswiri ndi kugwirizana kwamphasa ya fiberglass yokhala ndi utomoni wa epoxy.

Wodziwika bwino kwambirimipukutu ya mphasa yodulidwa ndi fiberglassGwiritsani ntchito chomangira ("guluu" chomwe chimagwirira ulusi waufupi pamodzi) chomwe chimapangidwa kuti chisungunuke mu styrene yomwe imapezeka mu polyester ndi vinylester resins.Epoxy ilibe styrene.

Malangizo a Akatswiri:Ngati mugwiritsa ntchito emulsion CSM yokhazikika yokhala ndi epoxy, chomangira sichingasungunuke. Mpandowo udzakhalabe wolimba, wovuta kugwira nawo ntchito, ndipo chomangiracho chidzakhala chotsika. Pa ntchito za epoxy, nthawi zonse yang'ananimphasa ya fiberglass yosalukidwazolembedwa kuti “zogwirizana ndi epoxy” kapena gwiritsani ntchitomphasa yosokera ya fiberglass, yomwe imagwiritsa ntchito kusoka kwamakina m'malo mwa zomangira za mankhwala.

5. Mafomu ndi Zosankha Zogulira: Mpukutu, Tepi, ndi Mtengo

Mukafunamphasa yagalasi yogulitsa, mawonekedwe ake amadalira kukula kwa polojekiti yanu:

Mpukutu wa Mat wa Fiberglass:Zabwino kwambiri popanga zinthu zazikulu kapena pansi pa bwato lonse. Kugula pansi lonsempukutu wa mphasa wodulidwa ndi fiberglassamachepetsa kwambirimtengo wa mphasa ya fiberglasspa sikweya phazi.

Tepi ya Mat ya Fiberglass:Izi ndi timizere topapatiza topangira matingi, toyenera kwambiri pokonza mipata yolimbitsa, malo olumikizirana, kapena mapaipi ang'onoang'ono.

Nsalu ya Mat ya Fiberglass:Kawirikawiri amagwiritsidwa ntchito mofanana mu zokambirana wamba, koma kwenikweni amatanthauza kuphatikiza kwa mphasa ndi nsalu zolukidwa zomwe zimagwiritsidwa ntchito mu ndondomeko ya laminate.

6. Malangizo Othandiza Pogwira Ntchito ndi Fiberglass Mat

Kugwiritsa Ntchito Utomoni:Lamulo lalikulu laMpando wa fiberglass wa ma ounces 1.5ndi chiŵerengero cha utomoni ndi galasi cha 2:1 kapena 3:1 potengera kulemera kwake. Popeza CSM ndi "yokonda ludzu," imafuna utomoni wambiri kuposa nsalu zolukidwa.

Kung'amba vs. Kudula:Mukagwiritsa ntchitothonje lodulidwa, nthawi zambiri zimakhala bwino kuteromisozim'mbali mwake osati kuzidula ndi lumo. M'mbali mwake zong'ambika zimapanga kusintha kwa "nthenga" komwe kumapangitsa kuti mipata isawonekere kwambiri mu laminate yomalizidwa.

Malo Osungira:Sungani yanumphasa yodulidwa ya ulusi wagalasipamalo ouma komanso ozizira. Chinyezi chingakhudze chomangira, zomwe zimapangitsa kuti mphasa ikhale yovuta kunyowetsa bwino.

Kutsiliza: Kupeza Mat Yoyenera ya Fiberglass Yogulitsa

Monga wopanga wamkulu wopita kumsika mwachindunji,CQDJimagwiritsa ntchito ukadaulo wapamwamba wopanga kuti ipereke zambirimbiri za mphasa za fiberglass ndi zophimba zapadera. Kuyambira mipukutu yamafakitale yambiri mpaka matepi opangidwa mwapadera, timapereka maziko a kapangidwe kake ka zinthu zophatikizika ndi kusasinthasintha kosayerekezeka komanso luso lolunjika ku fakitale. Kuchokeracsm 300 fiberglassntchito zopepuka mpaka zolemeramphasa yosokera ya fiberglassPofuna kukonza bwino kapangidwe kake, tikuonetsetsa kuti polojekiti yanu ikupitilirabe kuyesedwa kwa nthawi yayitali.

Kodi mukufuna mitengo yokwera kwambiri pa ma fiberglass chopped strand mat rolls kapena mukufuna mtengo wa 1708 biaxial mat?
