Izici Zobuchwepheshe Zolayini Wokukhiqiza Amapayipi we-Centrifugal Casting FRP

Ulayini wokukhiqiza wepayipi we-FRP oyicentrifugal uyinqubo ephumelelayo nenembayo yokukhiqiza amapayipi ayinhlanganisela. Izici zayo zobuchwepheshe zibonakaliswa ngokuyinhloko ezintweni ezibonakalayo, izinqubo zokukhiqiza, ukwakheka kwemishini, nokulawulwa kwekhwalithi yomkhiqizo. Lo mugqa usebenzisa{2}}isivinini esikhulu se-centrifugal force ukuze ubophe ngokugcwele i-resin ne-glass fibers, udale{3}}amandla aphezulu, imikhiqizo yamapayipi ukumelana nokugqwala{4}}. Le mikhiqizo isetshenziswa kakhulu ekunikezeni amanzi kanye nokukhipha amanzi, ubunjiniyela bamakhemikhali, kanye nokuphehla ugesi.

 

Izinzuzo Zokusebenza Okubalulekile

Amapayipi e-FRP asakazwa nge-Centrifugally asebenzisa i-fiber yengilazi-i-resin eqinisiwe{1}}esekelwe ezintweni eziyinhlanganisela enezici ezinhle kakhulu zomshini nokuzinza kwamakhemikhali. Imicu yengilazi inikeza amandla aphezulu kanye nokuqina, kuyilapho i-resin matrix inika ukugqwala okuhle kakhulu nokumelana nokuguga. Uma kuqhathaniswa namapayipi omdabu ensimbi noma kakhonkolo, amapayipi e-FRP anesisindo esincane, anamandla aqinile, futhi awathinteki ekugqwaleni okuvela emithonjeni yamakhemikhali njengama-acids, ama-alkali, nosawoti, okuholela empilweni yesevisi engaphezu kweminyaka engama-50. Ngaphezu kwalokho, udonga lwazo lwangaphakathi olubushelelezi nokumelana noketshezi oluphansi kunciphisa ngempumelelo ukusetshenziswa kwamandla kwezokuthutha.

Izici Zenqubo Yokukhiqiza

Umnyombo wenqubo ye-centrifugal casting usekujikelezweni-kwesivinini okuphezulu kwesikhunta, esabalalisa ngokulinganayo futhi sihlanganise i-resin nemicu yengilazi ngaphansi kwesenzo samandla amaphakathi. Le nqubo iqinisekisa ukujiya kwamapayipi afanayo, ukuminyana okuphezulu, nokungabikho kwamabhamuza kanye nokukhubazeka kwe-delamination ngokulawula ngokunembile isivinini sokujikeleza, izinga lokushisa, kanye nesikhathi sokuphulukisa. Imigqa yokukhiqiza ngokuvamile isebenzisa amasistimu okulawula azenzakalelayo ukuze kuqashwe futhi kulungiswe amapharamitha enqubo ngesikhathi sangempela ukuze kuqinisekiswe ukuhambisana nokuqina komkhiqizo. Uma kuqhathaniswa nezinqubo zokubekwa kwesandla-phezulu noma ukujikajika, ukusakaza kwe-centrifugal kunikeza ukusebenza kahle okuphezulu kokukhiqiza futhi kulungele-ukukhiqizwa kwezimboni ezinkulu.

Isakhiwo Sezisetshenziswa kanye Namaphuzu Avelele Ezobuchwepheshe

Izinto zokusebenza ezibalulekile emugqeni wokukhiqiza wepayipi we-FRP osakazwa yi-centrifugal zihlanganisa-i-centrifuge enesivinini esiphezulu, isistimu yokuhlanganisa inhlaka, idivayisi yokushisisa isikhunta, kanye nesistimu yokupholisa. I-centrifuge isebenzisa{2}}ama-bearings anemba aphezulu kanye nesistimu yokushayela ukuze kuqinisekiswe ukuzinza kwesikhunta ngesikhathi-siphenduka ngesivinini esikhulu, ukuvimbela ukudlidliza okungase kuthinte ikhwalithi yomkhiqizo. Uhlelo lokuxuba i-resin luhlanganisa kahle i-resin, i-ejenti yokwelapha, nesigcwalisi ukuze kuqinisekiswe izakhiwo ezibonakalayo ezingaguquki. Ukushisisa isikhunta ngokuvamile kusebenzisa ukufudumeza kukagesi noma isitimu ukuze kuqinisekiswe ukuphulukiswa ngokushesha kwe-resin ezingeni lokushisa elilungile, ukuthuthukisa ukusebenza kahle kokukhiqiza. Isistimu yokupholisa isebenzisa umoya noma ukupholisa amanzi ukuze ilawule ukuncipha kwamapayipi, inciphise ingcindezi yangaphakathi, futhi ithuthukise ukunemba kobukhulu.

Ukulawulwa Kwekhwalithi kanye Nezinzuzo Zemvelo

Ulayini wokukhiqiza ufakwe-ezisetshenziswa zokuhlola umugqa, njengamageji ogqinsi e-ultrasonic nezikena zokuqina kodonga, ukuze kuqashwe ukushuba kwamapayipi nokufana ngesikhathi sangempela ukuze kuqinisekiswe ukuthotshelwa kwezindinganiso zomkhakha. Ngaphezu kwalokho, inqubo yokukhiqiza amapayipi e-FRP ayikhiqizi amagesi ayingozi, ihlangabezana nezidingo zokuvikela imvelo, futhi izinto ezilahlwayo ziyasebenziseka kabusha, kwehlisa umthwalo wemvelo.

Kafushane, imigqa yokukhiqiza yamapayipi e-FRP e-centrifugally cast, enezakhiwo zayo ezinhle kakhulu zezinto ezibonakalayo, izinqubo ezisebenza kahle nezizinzile, okokusebenza okuhlakaniphile, kanye nezinzuzo ezihambisana nemvelo, isiphenduke isiqondiso esibalulekile sezobuchwepheshe ekukhiqizeni amapayipi esimanje, ehlinzeka ngezixazululo zamapayipi ezinokwethenjelwa neziqinile ezimbonini ezihlukahlukene.
