FRP Sandwich Structure Panels Ndi Zosiyanasiyana Zoyambira

FRP Sandwich Panels ndi zida zophatikizika zapamwamba zomwe zidapangidwa kuti zikwaniritse ntchito zambiri zamafakitale, malonda ndi zomangamanga. Gululi lili ndi zigawo zitatu zazikuluzikulu - zigawo ziwiri zakunja za pulasitiki yolimba yagalasi komanso chinthu chapakati pakatikati - zomwe zimaphatikiza mphamvu, mawonekedwe opepuka komanso kusinthasintha, kupangitsa kuti ikhale yopambana kuposa zida zakale monga chitsulo, matabwa kapena konkriti.

Zigawo zakunja za magalasi olimba a pulasitiki amapangidwa pophatikiza pulasitiki (nthawi zambiri poliyesitala, vinyl ester kapena epoxy resin) ndi utomoni wagalasi, zomwe zimapereka mphamvu zamakina, kukana dzimbiri komanso kukhazikika kwa mawonekedwe. Zomwe zili pakati pa zigawozi zimakhala ngati cholekanitsa chokhazikika, kupititsa patsogolo kuuma kwa gululo ndikuchepetsa kulemera konse. Kapangidwe kake kapadera kameneka kamathandizira mapanelo a FRP okhala ndi laminated kuti akhale ndi chiyerekezo champhamvu cha mphamvu ndi kulemera kwake, kuwapanga kukhala abwino kwa mapulogalamu omwe ali ndi katundu-kunyamula ndi kulimba ndikofunikira.

FRP Sandwich Panels ndi yoyamikiridwa kwambiri chifukwa chokana mankhwala, chinyezi, kuwala kwa ultraviolet ndi kutentha koopsa, kuonetsetsa kuti{0}}imagwira ntchito kwanthawi yayitali m'malo ovuta. Kuonjezera apo, amapereka kusinthasintha kwapangidwe monga makulidwe awo, mtundu, njira zothandizira pamwamba ndi miyeso zikhoza kusinthidwa malinga ndi zofunikira za polojekiti. Malo omwe amagwiritsidwa ntchito kawirikawiri amaphatikizapo denga la mafakitale ndi zokongoletsera zapakhoma, malo osungiramo firiji, zipinda zoyera, zoyendera (matupi agalimoto, zamkati mwa zombo) ndi zomangamanga.

Kuchita kwa gulu la masangweji a FRP kumadalira mgwirizano pakati pa zigawo zake zosiyanasiyana
Chipolopolo cha FRP:Awa ndi katundu-yomwe imapangitsa kuti muzitha kupindika, kukanikiza, ndi kupindika. Ulusi wagalasi-wolimba umawonjezera mphamvu, pomwe utomoni umateteza ulusiwu kuti usaonongeke komanso umalumikizana pamodzi. Kunenepa kwa chipolopolo (nthawi zambiri 0.5 - 3 mamilimita) kumatha kusinthidwa malinga ndi kapangidwe kake.
Zinthu zazikuluzikulu:Ntchito yayikulu yazinthu zazikuluzikulu ndikulekanitsa chipolopolo, kuti muwonjezere inertia yozungulira ya gulu (chizindikiro cha kukana kupindika), popanda kukulitsa kulemera kwake. Imathanso kuyamwa mphamvu zogwira ntchito ndikupereka kutsekemera kwamafuta.

Zida zodziwika bwino zimaphatikizapo:

Polyurethane (PU) thovu
poPolystyrene PS) thovu
polyPolyisocyanurate (PIR thovu)
Ure (wopangidwa ndi galasi-pulasitiki yolimba) Wamatabwa
