Ukushintsha kwezinga lokushisa ngesikhathi senqubo yokubumba ye-FRP kuyinkimbinkimbi kakhulu. Ngenxa yokuthi ipulasitiki iyisiqhubi sokushisa esibi, umehluko wokushisa phakathi kwesikhungo kanye nomphetho wezinto zokwakha mkhulu ekuqaleni kokubumba, okuzokwenza ukuthi ukusabela kokubopha kanye nokuxhumanisa kungaqali ngesikhathi esifanayo ezingqimbeni zangaphakathi nezangaphandle zezinto zokwakha.
Ngenxa yokungalimazi amandla nezinye izinkomba zokusebenza komkhiqizo, ukwandisa izinga lokushisa lokubumba ngokufanele kuyazuzisa ukufinyeza umjikelezo wokubumba nokuthuthukisa ikhwalithi yomkhiqizo.
Uma izinga lokushisa lokubumba liphansi kakhulu, akuzona nje izinto ezincibilikisiwe ezinobuthi obukhulu kanye nokugeleza okubi, kodwa futhi ngoba ukusabela kokuxhumanisa kunzima ukuqhubeka ngokugcwele, amandla omkhiqizo awaphezulu, ukubukeka kufiphele, futhi ukunamathela kwesikhunta kanye nokuguqulwa kokukhipha kwenzeka ngesikhathi sokususwa.
Izinga lokushisa lokubumba liyizinga lokushisa lokubumba elichazwe ngesikhathi sokubumba. Le pharamitha yenqubo inquma izimo zokudlulisa ukushisa kwesikhunta kuya ezintweni ezisemgodini, futhi inethonya elibalulekile ekuncibilikeni, ekugelezeni nasekuqineni kwezinto.
Izinto zengqimba engaphezulu zilungiswa kusenesikhathi ngokushisa ukuze zakhe ungqimba lwegobolondo eliqinile, kuyilapho ukuncishiswa kokuqina kamuva kwezinto zengqimba yangaphakathi kunqunyelwe ungqimba lwegobolondo eliqinile langaphandle, okuholela ekucindezelekeni okusele kokucindezelayo kungqimba engaphezulu yomkhiqizo obunjiwe, kanti ungqimba lwangaphakathi lukhona. Kukhona ukucindezeleka okusele kokucindezela, ukuba khona kokucindezeleka okusele kuzokwenza umkhiqizo ugobe, uqhekeke futhi wehlise amandla.
Ngakho-ke, ukuthatha izinyathelo zokunciphisa umehluko wokushisa phakathi kwangaphakathi nangaphandle kwezinto eziku-mold cavity nokuqeda ukungalingani kokuqina kungenye yezimo ezibalulekile zokuthola imikhiqizo esezingeni eliphezulu.
Izinga lokushisa lokubumba le-SMC lincike ekushiseni okuphezulu kwe-exothermic kanye nezinga lokuphisa lesistimu yokwelapha. Ngokuvamile izinga lokushisa elinezinga lokushisa eliphakeme lokuphisa eliphansi kancane liyizinga lokushisa lokuphisa, ngokuvamile elingaba ngu-135 ~ 170℃ futhi linqunywa ngokuhlola; izinga lokuphisa liyashesha Izinga lokushisa lesistimu liphansi, kanti izinga lokushisa lesistimu elinezinga lokuphisa elihamba kancane liphezulu.
Uma wenza imikhiqizo enezindonga ezincane, thatha umkhawulo ophezulu webanga lokushisa, futhi ukwakha imikhiqizo enezindonga ezinkulu kungathatha umkhawulo ophansi webanga lokushisa. Kodwa-ke, uma wenza imikhiqizo enezindonga ezincane enobubanzi obukhulu, umkhawulo ophansi webanga lokushisa kufanele futhi uthathwe ngenxa yenqubo ende yokuvimbela ukuqina kwezinto ngesikhathi senqubo yokugeleza.
