Kugwiritsa ntchito nsalu zophatikizika zamagalasi mu RTM ndi njira yolowetsera vacuum

Galasi fiber kompositi nsaluamagwiritsidwa ntchito kwambiri mu RTM (Resin Transfer Molding) ndi njira zolowetsera vacuum, makamaka muzinthu izi:

1. Kugwiritsa ntchito nsalu zophatikizika zamagalasi munjira ya RTM
Njira ya RTM ndi njira yopangirautomoniimabayidwa mu nkhungu yotsekedwa, ndipo fiber preform imayikidwa ndi kulimba ndi kutuluka kwa utomoni. Monga zida zolimbikitsira, nsalu zophatikizika zamagalasi zimagwira ntchito yofunika kwambiri pakupanga RTM.

1. （1）Kulimbitsa mphamvu: Nsalu zophatikizika zamagalasi zimatha kuwongolera bwino mawonekedwe amakanikidwe a magawo owumbidwa a RTM, monga kulimba kwamphamvu, mphamvu yopindika ndi kuuma, chifukwa champhamvu zawo komanso mawonekedwe apamwamba a modulus.
2. (2) Sinthani kuzinthu zovuta: Njira ya RTM imatha kupanga magawo okhala ndi mawonekedwe ovuta komanso mawonekedwe. Kusinthasintha ndi kapangidwe ka nsalu za galasi fiber composite zimathandiza kuti zigwirizane ndi zosowa za zinthu zovutazi.
3. (3) Kuwongolera ndalama: Poyerekeza ndi njira zina zopangira zinthu, ndondomeko ya RTM yophatikizidwa ndi nsalu zopangira magalasi zimatha kuchepetsa ndalama zopangira ndikuonetsetsa kuti zikugwira ntchito, ndipo ndizoyenera kupanga zazikulu.

2. Kugwiritsa ntchito galasi fiber composite nsalu mu ndondomeko vacuum kulowetsedwa
Njira yolowetsera vacuum (kuphatikiza VARIM, ndi zina zotero) ndi njira yopangira mimba.nsalu ya fiberkulimbitsa zinthu mu chatsekeka nkhungu patsekeke pansi vacuum zoipa kupsyinjika zinthu pogwiritsa ntchito otaya ndi malowedwe automoni, kenako kuchiritsa ndi kuumba. Galasi fiber composite nsalu imagwiritsidwanso ntchito kwambiri pochita izi.

• (1) Zotsatira za kulowetsedwa: Pansi pa kupanikizika kwa vacuum, utomoni ukhoza kudzaza nsalu zagalasi, kuchepetsa mipata ndi zolakwika, ndikuwongolera magwiridwe antchito onse.
• (2) Sinthani ku makulidwe akulu ndi magawo akulu akulu: Njira yolowetsera vacuum ili ndi zoletsa zochepa pakukula ndi mawonekedwe a chinthucho, ndipo itha kugwiritsidwa ntchito popanga makulidwe akulu ndi magawo akulu akulu, monga masamba a turbine, hulls, etc. Galasi fiber composite nsalu, monga kulimbikitsa zinthu, akhoza kukwaniritsa mphamvu ndi stiffness zofunika zigawozi.
• (3) Kutetezedwa kwachilengedwe: Monga ukadaulo wotsekera nkhungu, panthawi yautomonikulowetsedwa ndi kuchiritsa ndondomeko vakuyumu kulowetsedwa, kosakhazikika zinthu ndi poizoni mpweya zoipitsa ali m'thumba zingalowe filimu thumba, amene alibe zimakhudza kwambiri chilengedwe. Monga chinthu cholimbikitsira chopanda kuipitsidwa, nsalu yagalasi yokhala ndi fiber composite imathandiziranso kuteteza chilengedwe.

3. Zitsanzo zachindunji

• (1) M'munda wamlengalenga, nsalu zophatikizika zamagalasi zophatikizidwa ndi RTM ndi kulowetsedwa kwa vacuum zitha kugwiritsidwa ntchito kupanga mchira wowongoka wa ndege, mapiko akunja ndi zida zina.
• (2) M'makampani opanga zombo, nsalu zopangira magalasi zitha kugwiritsidwa ntchito popanga ma hull, ma decks ndi zida zina zamapangidwe.
• (3) M'munda wamagetsi amphepo, nsalu zophatikizika zamagalasi zimagwiritsidwa ntchito ngati zida zolimbikitsira ndikuphatikizidwa ndi njira yothira vacuum kuti apange masamba akulu amphepo.

Mapeto
Nsalu zophatikizika zamagalasi zimakhala ndi chiyembekezo chochulukirapo komanso chofunikira kwambiri mu RTM ndi njira zolowetsera vacuum. Ndi kupita patsogolo kosalekeza kwaukadaulo komanso kukhathamiritsa kosalekeza kwa njira, kugwiritsa ntchito nsalu zophatikizika zamagalasi munjira ziwirizi kudzakhala kozama komanso kozama.
