Lokhu kuthuthukisa ukumelana nokuqhekeka komgwaqo ngama-25% kanye nokumelana kwawo nama-rutting ngama-30%. Ngemva kokusebenzisa lobu buchwepheshe, ulayini wokuthutha amalahle eSifundazweni SaseShanxi ubone ukuphila kwawo komgwaqo kusuka eminyakeni emi-5 kuye kweyisi-8, kunciphisa utshalomali lonyaka wokulungisa ngama-yuan angaphezu kwezigidi ezimbili. Ngaphezu kwalokho, i-basalt fiber isetshenziselwa ukuqinisa imigwaqo evuzayo. Ukuphikiswa kwayo kwesimo sezulu kuqinisekisa ukuthi isakhiwo esikwazi ukungena ngaphakathi asibi brittle ngaphansi kwezinguquko zokushisa ukusuka ku--30 ° C kuya ku-60 ° C, futhi izinga layo lokungena lihlala lingaphezu kwama-80% isikhathi eside, lifaka isandla ekwakhiweni "kwemizi yesipontshi."

• Ingqalasizinda Yasolwandle: Imelana nokugqwala kwesifutho sikasawoti futhi yehlisa izindleko zokwakha.

  Amatheminali asolwandle, amathaneli awela ulwandle, nezinye izakhiwo zichayeka isikhathi eside esifuthweni sikasawoti omningi kanye nokuguguleka kwamagagasi. Izakhiwo zensimbi zomdabu zidinga ukususwa kokugqwala njalo nokupenda (ngezindleko zokulungisa zonyaka ezingaphezu kuka-10 yuan/m²). Kodwa-ke, amaphrofayili we-basalt fiber composite (njengamapayipi e-BFRP nezinqwaba) anesilinganiso sokugcina amandla esingu-95% ngemva kwamahora angu-1000 endaweni yesifutho sikasawoti futhi akudingi ukugcinwa kokulwa nokugqwala. Indawo yerentshi yasolwandle e-Shenzhen yasebenzisa izinqwaba ze-BFRP esikhundleni sezinqwaba zensimbi. Nakuba izindleko zenqwaba ngayinye zaziphakeme ngo-15%, inani lezindleko zomjikelezo wokuphila (ngaphezu kweminyaka engama-50) zehliswa ngama-40%, kuyilapho futhi kuvimbela ukungcoliswa kolwandle okubangelwa ukugqwala kwenqwaba yensimbi.
