1. Ukuphucula ukusebenza kweZakhiwo kunye noKwandisa uBomi beNkonzo

I-Fiber-reinforced polymer (FRP) i-composites ineempawu ezichukumisayo zomatshini, ezinomlinganiselo ophezulu kakhulu wamandla-to-weight kunezinto zokwakha zendabuko. Oku kuphucula umthamo wokuthwala umthwalo wesakhiwo ngelixa kunciphisa ubunzima baso ngokubanzi. Xa isetyenziselwa izakhiwo ezibanzi ezifana neetrasi zephahla okanye iibhulorho, amacandelo e-FRP afuna izakhiwo ezixhasayo ezimbalwa, ezinciphisa iindleko zesiseko kunye nokuphucula ukusetyenziswa kwendawo.

Ngokomzekelo, isakhiwo sophahla lwebala elikhulu elenziwe kwii-composites ze-FRP zilinganisa i-30% ngaphantsi kwesakhiwo sensimbi. Oku kunciphisa umthwalo kwisakhiwo esiphambili kunye nokuphucula ukuxhathisa kwe-corrosion, ukukhusela ngokufanelekileyo kwindawo yomswakama ngaphakathi kwendawo. Oku kwandise ubomi benkonzo yesakhiwo kwaza kwehlisa iindleko zokusilungisa ixesha elide.

 2. Ukuphucula iinkqubo zoKwakha ukuze kuphuculwe ukusebenza kakuhle

Ukukwazi ukwenza kwangaphambili kunye nokuvelisaIimbumba zeFRPkwiimodyuli zilula kakhulu ulwakhiwo. Kwimeko yefektri, ii-molds eziphambili kunye nezixhobo ezizenzekelayo zilawula ngokuchanekileyo inkqubo yokubumba, iqinisekisa umgangatho ophezulu, izixhobo zokwakha ezichanekileyo.

Kwizitayile zoyilo ezintsonkothileyo ezinje ngoyilo lwaseYurophu, iindlela zemveli zifuna ukuchitha ixesha kunye nomsebenzi onzima wokukrola owenziwe ngesandla kunye nokwakha, kunye neziphumo ezingahambelaniyo. I-FRP, nangona kunjalo, isebenzisa ubuchule bokubumba obuguquguqukayo kunye nemodeli ye-3D ukwenza i-molds yamacandelo anzima okuhlobisa, okuvumela ukuveliswa kobuninzi.

Kwiindawo zokuhlala ezitofotofo, iqela leprojekthi lasebenzisa iipaneli zokuhombisa ezenziwe ngaphambili zeFRP kwiindonga zangaphandle. Ezi zixhobo zombane zenziwa kumzi-mveliso zaza zathunyelwa kwindawo ukuze zidityaniswe. Xa kuthelekiswa nokwakhiwa kwezakhiwo zemveli kunye nokutyatyekwa, ixesha lokwakha liye lancitshiswa ukusuka kwiinyanga ezintandathu ukuya kwezintathu, ukunyuka okusebenzayo okuphantse kube ngama-50%. Iiphaneli zikwanazo nemithungo efanayo kunye nomgangatho ogudileyo, ziphucula kakhulu umgangatho wesakhiwo kunye nesibheno sobuhle, kwaye zifumana indumiso ephezulu kubahlali kunye nemarike.

3. Ukuqhuba uPhuhliso oluZinzileyo kunye nokuQeqesha iMigaqo yoKwakha ngokuHlaza

Imidibaniso ye-FRP inegalelo kuphuhliso oluzinzileyo kushishino lokwakha ngeenzuzo zabo ezinamandla zokusingqongileyo. Ukuveliswa kwezinto eziqhelekileyo ezifana nentsimbi kunye nesamente kunamandla amakhulu. Intsimbi ifuna ukunyibilikiswa kobushushu obuphezulu, obusebenzisa amafutha efosili njengamalahle kunye necoke kwaye ikhuphe ikharbon diokside. Ngokwahlukileyo, ukuveliswa kunye nokubunjwa kwee-composites ze-FRP zilula, zifuna ukushisa okuphantsi kunye namandla amancinci. Izibalo zobuchwephesha zibonisa ukuba ukuveliswa kwe-FRP kudla malunga ne-60% yamandla angaphantsi kwensimbi, ukunciphisa ukusetyenziswa kwezixhobo kunye nokukhutshwa kwekhabhoni kunye nokukhuthaza uphuhliso oluluhlaza oluvela kumthombo.

Imidibaniso ye-FRP nayo inenzuzo eyodwa kwi-recyclability. Ngelixa izixhobo zokwakha zesintu kunzima ukuphinda zisetyenziswe, i-FRP inokwahlulwa kwaye iphinde iphinde isetyenziswe iinkqubo ezikhethekileyo zokurisayikilishwa. Wachachaimicu yeglasiingaphinda isetyenziswe ukuvelisa iimveliso ezintsha ezidibeneyo, ukudala uqoqosho olujikelezayo olusebenzayo. Inkampani enkulu yokwenziwa kwemveliso iye yaseka inkqubo yokurisayikilisha apho izinto ezilahliweyo ze-FRP zityunyuzwa kwaye zihlolwe ukwenza iintsinga eziphinda zisetyenziswe, ezithi ke zisetyenziswe ukuvelisa iipaneli zokwakha kunye nezinto zokuhombisa. Oku kunciphisa ukuthembela kwimithombo emitsha kwaye kunciphisa umthwalo wokusingqongileyo wenkunkuma.

Ukusebenza kokusingqongileyo kwe-FRP kwizicelo zokwakha nako kuyaphawuleka. Ekwakhiweni kwesakhiwo seofisi esisebenza ngamandla, i-FRP yayisetyenziselwa iindonga, idibaniswe noyilo oluphezulu lwe-thermal insulation design. Oku kunciphise kakhulu ukufudumeza kwesakhiwo kunye nokusetyenziswa kwamandla okupholisa. Ubalo lubonisa ukuba ukusetyenziswa kwamandla kwesi sakhiwo bekungaphantsi kwama-20% kunezakhiwo zemveli, ukunciphisa kakhulu ukuxhomekeka kwaso kumafutha efosili njengamalahle kunye negesi yendalo kunye nokuthoba ukukhutshwa kwekhabhoni. I-microstructure ekhethekileyo ye-FRP ibonelela ngokugqwesileyo kwe-thermal kunye nobomi benkonzo ende, kunye nokusetyenziswa kwayo kunciphisa inkunkuma yokwakha eveliswa kulondolozo lwezakhiwo kunye nokulungiswa.

Njengoko imimiselo yokusingqongileyo iba ngqongqo, iinzuzo ezizinzileyo zeIimbumba zeFRPkushishino lokwakha ziya zibonakala ngakumbi. Ukwamkelwa ngokubanzi kwesi sixhobo kwiiprojekthi ezahlukeneyo-ukusuka kwiindawo zokuhlala ukuya kwizakhiwo zorhwebo, kunye neendawo zoluntu ukuya kwizityalo zoshishino-zibonelela ngesisombululo esifanelekileyo sokutshintsha kweshishini. Njengoko iinkqubo zokurisayikilisha ziphucuka kunye nobuchwepheshe obunxulumeneyo buhambela phambili, i-FRP iya kudlala indima enkulu ngakumbi kwicandelo lokwakha, iqinise ngakumbi i-carbon ephantsi kunye neempawu ezihambelana nokusingqongileyo kwaye ifake isandla kwimpumelelo yeenjongo zophuhliso oluzinzileyo.
