Ukushintsha kwezinga lokushisa ngesikhathi senqubo yokubumba ye-FRP kuyinkimbinkimbi kakhulu.Ngenxa yokuthi ipulasitiki ingumqhubi ompofu wokushisa, umehluko wokushisa phakathi kwesikhungo kanye nonqenqema lwempahla mkhulu ekuqaleni kokubunjwa, okuzokwenza ukuthi ukusabela kokuphulukisa nokuxhumanisa kungaqali ngesikhathi esifanayo ngaphakathi nangaphakathi. izingqimba zangaphandle zezinto.
Ngokwesisekelo sokungalimazi amandla nezinye izinkomba zokusebenza komkhiqizo, ukukhulisa ngokufanelekile izinga lokushisa lokubumba kunenzuzo ukufinyeza umjikelezo wokubumba nokuthuthukisa ikhwalithi yomkhiqizo.
Uma izinga lokushisa lokubumba liphansi kakhulu, hhayi nje kuphela izinto ezincibilikisiwe ezine-viscosity ephezulu kanye ne-fluidity empofu, kodwa futhi ngenxa yokuthi ukusabela kwe-crosslinking kunzima ukuqhubeka ngokugcwele, amandla omkhiqizo awaphezulu, ukubukeka kufiphele, nokunamathela kwesikhunta kanye ne-ejection deformation. kwenzeka ngesikhathi sokukhulelwa.
Izinga lokushisa lokubumba izinga lokushisa lesikhunta elicaciswe ngesikhathi sokubumba.Le pharamitha yenqubo inquma izimo zokudlulisa ukushisa kwesikhunta ezintweni ezisemgodini, futhi inethonya eliwujuqu ekuncibilikeni, ukugeleza nokuqiniswa kwezinto.
Indwangu yongqimba olungaphezulu yelashwa ekuqaleni ukushisa ukuze yakhe ungqimba lwegobolondo eliqinile, kuyilapho ukushwabana kwakamuva kongqimba lwangaphakathi kunqunyelwe ungqimba lwegobolondo eliqinile langaphandle, okuholela ekucindezelekeni okusalayo okucindezelayo ongqimbeni olungaphezulu lomkhiqizo obunjiwe, futhi ungqimba lwangaphakathi luthi Kukhona ukucindezelwa okusalayo, ukuba khona kwengcindezi eyinsalela kuzodala ukuthi umkhiqizo ugoqe, uqhekeke futhi wehlise amandla.
Ngakho-ke, ukuthatha izinyathelo zokunciphisa umehluko wokushisa phakathi kwangaphakathi nangaphandle kwempahla emgodini wesikhunta nokuqeda ukuphulukiswa okungalingani kungenye yezimo ezibalulekile zokuthola imikhiqizo yekhwalithi ephezulu.
Izinga lokushisa lokubumba i-SMC lincike ekushiseni okuphezulu kwe-exothermic kanye nezinga lokuphulukisa lesistimu yokwelapha.Ngokuvamile izinga lokushisa elinezinga lokushisa eliphakeme elipholile elipholile liyibanga lokushisa elilaphayo, ngokuvamile eliba ngu-135℃ futhi elinqunywa ngokuhlolwa;izinga lokuphulukisa liyashesha Izinga lokushisa lesistimu liphansi, futhi izinga lokushisa lesistimu elinezinga eliphansi lokuphulukisa liphakeme.
Lapho wenza imikhiqizo enezindonga ezincane, thatha umkhawulo ophezulu wezinga lokushisa, futhi ukwenza imikhiqizo enezindonga eziwugqinsi kungathatha umkhawulo ophansi webanga lokushisa.Kodwa-ke, lapho wenza imikhiqizo enezindonga ezincane ngokujula okukhulu, umkhawulo ophansi webanga lokushisa kufanele futhi uthathwe ngenxa yenqubo ende yokuvimbela ukuqina kwezinto ngesikhathi sokugeleza.
