FRP lining inzira yakajairika uye inonyanya kukosha yekudzora ngura mukuvaka kwakasimba kwekudzivirira ngura. Pakati payo, FRP yekugadzika nemaoko inoshandiswa zvakanyanya nekuda kwekushanda kwayo kuri nyore, nyore uye kuchinjika. Zvinogona kutaurwa kuti nzira yekugadzika nemaoko inodarika 80% yehuwandu hweFRP yekudzivirira ngura. "Zvinhu zvitatu zvikuru" resin, fiber uye powder fiber muFRP yakaiswa nemaoko ndiyo skeleton yeFRP, inotsigira simba reFRP system, uye chikamu chakakosha chekuzadzisa mhedzisiro yenguva refu yekudzivirira ngura yeFRP.
Zvichienderana nemusiyano wenzvimbo inoora nepakati, zvinhu zviri muFRP zvichachinjawo. Kusarudzwa kwezvinhu zvine mwero panguva yekuvaka chinhu chakakosha kuti chigadzirwa cheFRP chapedzwa chigone kuenderana nenzvimbo inoora uye kugara kwayo kwenguva refu. Nokudaro, kusarudzwa kwezvinhu zvinosimbisa FRP kunofanirwa kusarudzwa usati wavaka. Semuenzaniso, zvinhu zvinosimbisa zvinomiririrwa nefiber yegirazi ndizvo zvinhu zvinonyanya kushandiswa mufiber, zvinogona kuramba ngura yakawanda; zvisinei, hazvidziviriri hydrofluoric acid uye ngura inopisa yephosphoric acid. Shandisa polyester, polypropylene uye mamwe machira efiber eorganic uye felt, unogona zvakare kusarudza kushandisa linen kana degreased gauze, uye zvimwe zvigadzirwa zveFRP zvinoda kuramba ngura uye conductivity, unogona kusarudza zvinhu zvecarbon fiber. Neimwe nzira, kusarudzwa kwefiber yakasimbiswa yeFRP nemaoko ipfungwa yehunyanzvi neruzivo iyo tekinoroji yekudzivirira ngura nevagadziri vanofanira kuidzidza.
Muzvigadzirwa zveFRP zvakanamirwa, mafiber mazhinji ekusimbisa ifiber yegirazi, ingave jira, felt kana shinda. Chikonzero chikuru ndechekuti pamusoro pemutengo, inewo hunhu hwakanaka hunotevera:
01 Kusagona kushandisa makemikari
Machira efiberglass asina kugadzirwa haaore, haavhurike kana kuora. Anoramba maacid akawanda kunze kwehydrofluoric nehot phosphoric acid.
02 Kugadzikana kwakakura
Shinda dzegirazi dzinoshandiswa kugadzira machira egirazi hadzitambanudzike kana kuderera nekuda kwekuchinja kwemamiriro ekunze. Kureba kwechimiro panguva yekuputsika kwegirazi i3-4%. Avhareji yekuwedzera kwekupisa kwegirazi reE-glass ine linear thermal expansion i5.4 × 10-6 cm/cm/°C.
03 Kushanda zvakanaka kwekupisa
Machira eFiberglass ane mwero wakaderera wekuwedzera kwekupisa uye mwero wekupisa wakakwira. Fiberglass inobvisa kupisa nekukurumidza kupfuura asbestos kana organic fibers.
04 Simba guru rekudhonza
Shinda yefiberglass ine chiyero chakasimba chekusimba nehuremu. Paundi imwe chete yeshinda yefiberglass yakasimba zvakapetwa kaviri pane waya yesimbi. Kugona kugadzira simba remachira rinoenderana nedivi rimwe chete kana maviri kunowedzera kuchinjika kwezvinhu zvinoshandiswa pakugadzira.
05 Kudzivirira kupisa kwakanyanya
Magirazi asina kugadzirwa haatsvi uye haapiswi zvakanyanya nekuda kwekupisa kwakanyanya kunowanzoonekwa mumaindasitiri. Fiberglass inoramba iine simba rayo rinosvika 50% pa700°F uye 25% pa1000°F.
06 Kusanyanya kuchena
Shinda dzefiberglass dzakagadzirwa neshinda dzisina maburi saka dzine hunyoro hushoma.
07 Kudzivirira kwemagetsi kwakanaka
Simba guru remagetsi emagetsi uye kusagadzikana kwakaderera kwemagetsi emagetsi, pamwe chete nekusapinza mvura zvakanaka uye kuramba kupisa kwakanyanya, zvinoita kuti machira efiberglass ave akanaka pakudzivirira kupisa kwemagetsi.
08 Kuchinjika kwechigadzirwa
Matavi akapfava anoshandiswa mushinda dzefiberglass, saizi dzakasiyana-siyana dzeshinda uye magadzirirwo adzo, mhando dzakasiyana dzeshinda, uye zvakawanda zvakakosha zvinoita kuti machira efiberglass abatsire pakushandiswa kwakasiyana-siyana kwemaindasitiri.
09 mutengo wakaderera mutengo wakaderera
Machira efiberglass anogona kuita basa racho uye anodhura zvakaenzana nemachira efiber ekugadzira uye echisikigo.
Saka, girazi fiber chinhu chakakodzera chekusimbisa FRP nemaoko, icho chisingadhuri, chisingadhuri, uye chiri nyore kushandisa. Ndiyo imwe yezvinhu zvinoshandiswa zvakanyanya pakati pezvinhu zvakawanda zvekusimbisa pari zvino.
