Kuvandudza simba rekupwanya kwejira refiberglasszvinogona kuitwa nenzira dzakasiyana-siyana:
1. Kusarudza musanganiswa wakakodzera wefiberglass:Simba remagirazi emhando dzakasiyana-siyana rinosiyana zvikuru. Kazhinji, kana fiberglass ine alkali yakawanda (yakadai seK2O, uye PbO), simba rayo rinoderera. Saka, kusarudza magirazi ane alkali shoma kunogona kuwedzera simba rawo.
2. Kudzora dhayamita nehurefu hwemagirazi:Kana dhayamita yacho yakatetepa uye kureba kwemachira egirazi, ndipo panowanzova nesimba. Huwandu nehukuru hwema "microcracks" zvinoderera nedhayamita nekureba, nokudaro zvichiwedzera simba remagirazi egirazi.
3. Gadzirisa maitiro ekugadzira:Munguva yekugadzira, matanho ekudhirowa shinda, kuruka, kuputira, uye kupukuta jira anodzorwa zvakasimba kuti ave nechokwadi chekuti jira racho rakaenzana uye rakanaka. Semuenzaniso, shandisa michina yekuruka nekuputira yehunyanzvi uye gadzirisa nguva yekupukuta nekupisa kuti uwane hunhu hwakanakisa hwemuchina.
4. Dzivisa kuchengetedza kwenguva refu:Matayi egirazi anoora panguva yekuchengetwa nekuda kwekunyungudika kwehunyoro mumhepo, zvichikonzera kurasikirwa nesimba. Nokudaro, kuchengetwa kwenguva refu kunofanira kudzivirirwa uye matanho akakodzera ekudzivirira hunyoro anofanira kutorwa.
5. Shandisa namatidziro yakakodzera:Pakusarudza chinamira, zvinhu zvinokonzera ngura yemakemikari kufiberglass zvinofanira kudzivirirwa, kunyanya zvinhu zvine zvicherwa zvinonyudza mvura yakawanda. Mortar yakachena isina simende inogona kugadzira polymerjira refiberglassinoshanda kwenguva yakareba nekuda kwengura isiri yealkali uye kushoma kwemvura.
