Asayansi aku Russia apereka lingaliro la kugwiritsa ntchito ulusi wa basalt ngati zida zolimbikitsira zida zamlengalenga.Kamangidwe kameneka kamakhala ndi mphamvu yabwino yonyamula katundu ndipo imatha kupirira kusiyana kwakukulu kwa kutentha.Kuphatikiza apo, kugwiritsa ntchito mapulasitiki a basalt kudzachepetsa kwambiri mtengo wa zida zaukadaulo zakunja.
Malinga ndi pulofesa wothandizira ku dipatimenti ya Economics and Industrial Production Management ku Perm University of Technology, pulasitiki ya basalt ndi zinthu zamakono zozikidwa pa ulusi wa miyala ya magmatic ndi zomangira organic.Ubwino wa ulusi wa basalt poyerekeza ndi ulusi wamagalasi ndi ma aloyi azitsulo amakhala pamakina awo apamwamba kwambiri, akuthupi, amankhwala komanso amafuta.Izi zimathandiza kuti zigawo zochepa zivulazidwe panthawi yolimbitsa, popanda kuwonjezera kulemera kwa chinthucho, ndi kuchepetsa ndalama zopangira maroketi ndi ndege zina.

Ofufuzawo akuti kompositiyo itha kugwiritsidwa ntchito ngati zoyambira pamakina a rocket.Ili ndi zabwino zambiri kuposa zida zomwe zimagwiritsidwa ntchito pano.Kulimba kwazinthu kumakhala kokulirapo pamene ulusi wayikidwa pa 45 ° C.Pamene chiwerengero cha zigawo za masanjidwe pulasitiki basalt ndi oposa 3 zigawo, akhoza kupirira kunja mphamvu.Kuphatikiza apo, kusamuka kwa axial ndi ma radial a mapaipi apulasitiki a basalt ndi maulalo awiri ocheperako kuposa mapaipi a aloyi a aluminiyamu omwe ali pansi pa makulidwe omwewo a zinthu zophatikizika ndi chotengera cha aluminium alloy casing.
