1. Ukuphucula ukusebenza kwesakhiwo kunye nokwandisa ubomi benkonzo

Ii-composites ze-fiber-reinforced polymer (FRP) zineempawu ezintle zoomatshini, ezinomlinganiselo ophezulu kakhulu wamandla-ubunzima kunezixhobo zokwakha zemveli. Oku kuphucula amandla esakhiwo okuthwala umthwalo ngelixa kunciphisa nobunzima baso ngokubanzi. Xa zisetyenziselwa izakhiwo ezinkulu ezifana nee-roof trusses okanye ii-bridges, izinto ze-FRP zifuna izakhiwo ezimbalwa ezixhasayo, nto leyo enciphisa iindleko zesiseko kwaye iphucule ukusetyenziswa kwendawo.

Umzekelo, uphahla lwesakhiwo esikhulu semidlalo esenziwe ngee-FRP composites lwalunobunzima obungaphantsi ngama-30% kunesakhiwo sentsimbi. Oku kunciphisa umthwalo kwisakhiwo esiphambili kwaye kwaphucula ukumelana nokugqwala, kwasikhusela ngokufanelekileyo kwindawo efumileyo ngaphakathi kwendawo. Oku kwandisa ubomi benkonzo yesakhiwo kwaye kunciphisa iindleko zokulungisa ixesha elide.

 2. Ukuphucula iinkqubo zokwakha ukuze kuphuculwe ukusebenza kakuhle

Ubuchule bokwenza izinto kwangaphambili nokuvelisaIi-FRP compositeskwiimo zemodyuli zenza kube lula kakhulu ukwakhiwa. Kwindawo yefektri, iimolds eziphambili kunye nezixhobo ezizenzekelayo zilawula ngokuchanekileyo inkqubo yokubumba, ziqinisekisa ukuba izixhobo zokwakha ezikumgangatho ophezulu nezichanekileyo.

Kwiindlela zokwakha ezintsonkothileyo ezifana noyilo lwaseYurophu, iindlela zemveli zifuna ixesha elide kwaye zifuna umsebenzi omkhulu wokuzoba ngesandla kunye nokwakha, kwaye iziphumo aziguquguquki. Nangona kunjalo, i-FRP isebenzisa iindlela zokubumba eziguquguqukayo kunye nemodeli ye-3D ukwenza iimolds zezinto zokuhombisa ezintsonkothileyo, okuvumela imveliso enkulu.

Kwindawo yokuhlala ekumgangatho ophezulu, iqela leprojekthi lisebenzise iiphaneli zokuhombisa ze-FRP ezenziwe kwangaphambili kwiindonga zangaphandle. Ezi paneli zenziwe kumzi-mveliso zaza zathuthwa zaya kwindawo ukuze zihlanganiswe. Xa kuthelekiswa nokwakhiwa kwezakhiwo kunye nokuplasta kwendabuko, ixesha lokwakha lancitshiswa ukusuka kwiinyanga ezintandathu ukuya kwezintathu, ukwanda kokusebenza kakuhle okuphantse kube ngama-50%. Ezi paneli zazineemithungo ezifanayo kunye nomphezulu ogudileyo, ziphucula kakhulu umgangatho wesakhiwo kunye nobuhle baso, kwaye zafumana udumo olukhulu kubemi nakwimarike.

3. Ukuqhuba Uphuhliso Oluzinzileyo kunye Nokusebenzisa Imigaqo Yokwakha Okuluhlaza

Ii-FRP composites zinegalelo kuphuhliso oluzinzileyo kwishishini lokwakha kunye neenzuzo zazo ezinamandla kwindalo esingqongileyo. Ukuveliswa kwezinto zemveli ezifana nentsimbi kunye nesamente kufuna amandla amaninzi. Intsimbi ifuna ukunyibilikisa ubushushu obuphezulu, okusebenzisa amafutha efosili afana namalahle kunye ne-coke kwaye ikhuphe i-carbon dioxide. Ngokwahlukileyo koko, ukuveliswa kunye nokubumba ii-FRP composites kulula, kufuna amaqondo obushushu aphantsi kunye namandla amancinci. Ubalo lobuchwephesha lubonisa ukuba imveliso ye-FRP isebenzisa amandla angaphantsi ngama-60% kunentsimbi, nto leyo enciphisa ukusetyenziswa kwezixhobo kunye nokukhutshwa kwekhabhoni kwaye ikhuthaza uphuhliso oluluhlaza oluvela kumthombo.

Ii-FRP composites nazo zinenzuzo ekhethekileyo ekusetyenzisweni kwakhona. Nangona izixhobo zokwakha zemveli kunzima ukuzisebenzisa kwakhona, i-FRP inokuqhekeka kwaye iphinde isetyenzwe kusetyenziswa iinkqubo ezikhethekileyo zokusebenzisa kwakhona.iifayibha zeglasiingasetyenziselwa ukuvelisa iimveliso ezintsha ezidityanisiweyo, nto leyo edala uqoqosho olujikelezayo olusebenzayo. Inkampani enkulu yokuvelisa izinto ezidityanisiweyo iseke inkqubo yokuphinda isetyenziswe apho izinto ezilahliweyo ze-FRP zityunyuzwa kwaye zihlolwe ukuze kwenziwe imicu ephinda isetyenziswe, ezithi emva koko zisetyenziswe ukuvelisa iiphaneli zokwakha kunye nezinto zokuhombisa. Oku kunciphisa ukuxhomekeka kwizixhobo ezintsha kwaye kunciphisa umthwalo wenkunkuma kwindalo esingqongileyo.

Ukusebenza kwe-FRP kwizakhiwo nako kuyaphawuleka. Ekwakhiweni kwesakhiwo seofisi esisebenzisa amandla amaninzi, i-FRP yasetyenziswa kwiindonga, idityaniswe noyilo lwe-thermal insulation olusebenza kakuhle kakhulu. Oku kunciphisa kakhulu ukusetyenziswa kwamandla okufudumeza nokupholisa kwesakhiwo. Izibalo zibonisa ukuba ukusetyenziswa kwamandla kwesi sakhiwo kwakungaphantsi ngama-20% kunezakhiwo zemveli, kunciphisa kakhulu ukuxhomekeka kwaso kumafutha efosili afana namalahle kunye negesi yendalo kunye nokunciphisa ukukhutshwa kwekhabhoni. Isakhiwo esincinci se-FRP esikhethekileyo sinika i-thermal insulation egqwesileyo kunye nobomi benkonzo ende, kwaye ukusetyenziswa kwayo kunciphisa nenkunkuma yokwakha evela kulondolozo kunye nokuhlaziywa kwesakhiwo.

Njengoko imithetho yokusingqongileyo isiya iqina, iingenelo ezizinzileyoIi-FRP compositeskushishino lokwakha kuya kucaca ngakumbi. Ukwamkelwa ngokubanzi kwezi zinto kwiiprojekthi ezahlukeneyo—ukusuka kwiindawo zokuhlala ukuya kwizakhiwo zorhwebo, kunye nezibonelelo zikawonke-wonke ukuya kwizityalo zoshishino—kubonelela ngesisombululo esisebenzayo sotshintsho oluluhlaza kushishino. Njengoko iinkqubo zokuphinda zisetyenziswe ziphucuka kwaye ubuchwepheshe obunxulumene nazo buqhubela phambili, i-FRP iya kudlala indima enkulu ngakumbi kwicandelo lokwakha, iqinisa ngakumbi iimpawu zayo eziphantsi kwekhabhoni kunye nokusingqongileyo kwaye inegalelo ekufezekisweni kweenjongo zophuhliso oluzinzileyo.
