Ucwaningo ngokusebenza kokunamathela kwezinto eziqiniswe nge-basalt fiber ezine-tendon ze-BFRP

Izici eziyinhloko ezithonya ukusebenza kokubopha

1. Ukunciphisa umthamo we-fiber kanye nobude

Ukwelashwa nge-volume doping I-Basalt intambo emfushane inomthelela omkhulu emandleni okubopha, futhi ukuhlolwa kukhombisa ukuthi i-doping yevolumu engu-0.2% inomphumela omuhle kakhulu ekuthuthukisweni kwamandla okubopha, futhi i-doping ngokweqile ingase iholele ekwehleni kokusebenza ngenxa yokuhlanganiswa kwefayibha.

Ubude befayibha (isb. 6mm kanye no-18mm) abunawo umphumela omkhulu emandleni esibopho, kodwa imicu emifushane ihlakazeka kalula ukuze kuncishiswe amaphutha e-interfacial.

2. Uhlobo lwamandla lwekhonkrithi ephinde yasetshenziswa

Ukwandisa izinga lamandla ekhonkrithi ephinde yasetshenziswa (isb., kusukela ku-C30 kuya ku-C40) kuthuthukisa amandla esibopho phakathi kwe-BUkuqinisa i-Frp kanye ne-substrate, kodwa ukwanda kunqunyelwe, futhi i-interface isengozini yokuqhekeka uma izinga lamandla liphezulu kakhulu.

3. Ukwelashwa kwe-interface kanye ne-ejenti yokuxhumanisa

Ukuqhumisa isihlabathi ebusweni I-BFRP Ukuqinisa kungandisa ubulukhuni futhi kuthuthukise amandla okuluma okwenziwa ngomshini; ukwengeza i-ejenti yokuhlanganisa i-silane kungathuthukisa ukubopha kwamakhemikhali phakathi kwe-fiber ne-resin matrix futhi kunciphise ukushelela kwe-interfacial.

Ukuhlolwa kanye nezindlela zezakhiwo zokunamathela

1. Ukuhlolwa kokukhipha okuphakathi

Ijika le-bond-slip lifundwe ngokuhlolwa kokudonsa, kwatholakala ukuthi imodi yokulimala kwe-bond yayiwukudonsa imisipha noma ukuqhekeka kwekhonkrithi. imicu ye-basalt kungabambezela umonakalo ophukayo wekhonkrithi futhi kuthuthukise ukuqina kwayo.

Ububanzi obujwayelekile bamandla ebhondi buyi-6-12 MPa, futhi inani elithile lithintwa yisilinganiso sefayibha, ububanzi bokuqinisa (isb., 16 mm) kanye nenqubo yokwelapha i-interface.

2. Imodeli yokusatshalaliswa kokucindezeleka kwebhondi

Ukucindezeleka kwesibopho kusatshalaliswa ngokungaqondile ngobude bokuqina, futhi ukucindezeleka okuphezulu kugxile ekugcineni kokulayisha. Imodeli yethiyori idinga ukucabangela ukumelana nokwelulwa kokuqhekeka kanye nomphumela wokungqubuzana kwesikhonkrithi esiqiniswe ngefayibha.

Izinzuzo zohlelo lokusebenza kanye namacala obunjiniyela

1. Ukumelana nokugqwala nokuqina

Ukuqinisa i-BFRP kugcina amandla ayo okubopha angaphezu kuka-90% ezindaweni zokuguguleka kwe-chloride ion (isb., ubunjiniyela basolwandle), okungcono kakhulu kunezinsimbi zokuqinisa insimbi ne-fiberglass.

Isibonelo: Ibhuloho laseQingdao Cross-Sea lamukela ukuqinisa kwe-BFRP ukuze kuthathelwe indawo ukuqinisa kwensimbi, futhi isikhathi sokuphila kwalo sinwetshwe saba ngaphezu kweminyaka eyi-100.

2. Ukusebenza Okulula Nokuzamazama Komhlaba

Ubuningi bokuqinisa i-BFRP buyi-1/4 kuphela yensimbi, engasetshenziswa ukuqinisa imishayo yekhonkrithi ukuze kuncishiswe isisindo sesakhiwo ngo-20%-30%, futhi ngesikhathi esifanayo kuthuthukiswe amandla okusetshenziswa kwamandla okuzamazama komhlaba ngokusonga ukuqinisa.

Izinselele Ezikhona kanye Nesiqondiso Sokuthuthukisa

1. Ukuqinisa isibopho sobuso

Inkinga ekhona: Ukuxhumana phakathi kwemicu kanye ne-matrix yesimende kuthambekele ekuqhekekeni ngenxa yokugxila kokucindezeleka, futhi ama-interfacial agents aguquliwe (isb., i-nano-SiO₂ doped) kudingeka athuthukiswe ukuze kuthuthukiswe ukubopha kwamakhemikhali.

2. Ukusebenza kwesikhathi eside kanye nokuhlelwa kwesimo

Ukuntuleka kwedatha yokukhukhuleka kwesikhathi eside ngaphansi kokushisa okuphezulu kanye nomswakama ophezulu (isb., iminyaka engaphezu kwe-10), kudingeka ukuhlolwa kokuguga okusheshayo ukuqinisekisa; imininingwane yokuklama ayikafani kuwo wonke amazwe, futhi yize iShayina ikhiphe indinganiso ye-GB/T 38143-2019, iziqondiso zokuklama imininingwane zisadinga ukuthuthukiswa.

3. Umklamo wokubambisana obanzi

Esikhathini esizayo, singahlola ubuchwepheshe obuhlanganisiwe be- I-BFRP ukuqinisa kanye ne-fiber yensimbi/i-carbon fiber ukwakha izinhlanganisela ze-gradient nokulinganisela amandla kanye nokuguquguquka.

Iziqondiso Zocwaningo Lwesikhathi Esizayo  

1. Ukuqapha okuhlakaniphile kanye nokumodela kwedijithali

Izinzwa ze-fiber optic ezifakiwe kuma-tendon e-BFRP, ukuqapha ngesikhathi sangempela kokucindezeleka kwe-bond interface kanye nokuthuthukiswa koqhekeko, kuhlanganiswe nokulingisa kwezinto ezilinganiselwe ukuze kuthuthukiswe umklamo.

2. Inqubo yokulungiselela i-carbon ephansi

Nciphisa ukuncibilika kwe-basalt fiber kanye nokushisa okudonselayo (njengamanje okungu-1400-1500 ℃), ukuthuthukiswa kwe-resin yokwelapha ephansi ukuze kuncishiswe ukusetshenziswa kwamandla.

3. Ukusetshenziswa kahle kwezinto ezisetshenzisiwe

Hlanganisa i-aggregate ephinde yasetshenziswa kanye ne-basalt fiber kanye nemfucuza yokwakha ukuze ukhuthaze uhlelo lwezinto zokwakha eziluhlaza "olungavuselelwa konke" futhi unciphise ukusetshenziswa kwezinsiza.

Isifinyezo

Ucwaningo mayelana nokusebenza kokubopha kwezinto zokwakha eziqiniswe nge-basalt fiber kanye I-BFRP I-tendon ifinyelele imiphumela yesigaba ngesigaba, kodwa ukusetshenziswa kwayo okukhulu kusadingeka kudlule ezinkingeni zokwenza ngcono i-interfacial, ukuqinisekiswa kokuqina kwesikhathi eside kanye nomklamo ojwayelekile. Esikhathini esizayo, ngokusebenzisa izinto ezintsha eziningi (isib. izinto ezihlakaniphile, izinqubo ezisebenzisa ikhabhoni ephansi), kulindeleke ukuthi ifinyelele impumelelo kwezobuchwepheshe emikhakheni yobunjiniyela basolwandle kanye nokuqinisa ukumelana nokuzamazama komhlaba, futhi isize ekuthuthukisweni kwezakhiwo ezisimeme.
