Apie 230 000 eur\u0173 vert\u0117s prietaisas i\u0161siskiria pla\u010diu temperat\u016br\u0173 diapazonu ir keli\u0173 analiz\u0117s metod\u0173 integracija, tod\u0117l leid\u017eia tirti \u012fvairius kompozitus, perdirbtas \u017ealiavas, energijos kaupimo med\u017eiagas ir kitas sistemas.\u00a0<\/p>\n
\u201eVienalaik\u0117 termin\u0117 analiz\u0117 (STA) sujungia termogravimetrij\u0105 (TGA) ir dinamin\u0119 diferencin\u0119 skenuojam\u0105j\u0105 kalorimetrij\u0105 (DSC) vienoje matavimo sistemoje, o tai leid\u017eia vienu metu registruoti mas\u0117s poky\u010dius ir \u0161ilumos srautus tame pa\u010diame m\u0117ginyje identi\u0161komis s\u0105lygomis\u201c, \u2013 dalijasi vienas i\u0161 projekto vykdytoj\u0173, VILNIUS TECH Kompozitini\u0173 med\u017eiag\u0173 laboratorijos mokslininkas dr. Rimvydas Stonys.<\/p>\n
\u0160is metodas suteikia tiksli\u0105 ir i\u0161sami\u0105 informacij\u0105 apie termin\u012f stabilum\u0105, fazinius virsmus, oksidacijos ir redukcijos reakcijas bei skilimo procesus.<\/p>\n
\u201eTikslinga med\u017eiag\u0173 termin\u0117 analiz\u0117 yra b\u016btina, nes b\u016btent ji nulemia med\u017eiag\u0173 ilgaam\u017ei\u0161kum\u0105, konstrukcij\u0173 saugum\u0105, gamini\u0173 tarnavimo trukm\u0119 bei energijos vartojimo efektyvum\u0105\u201c, \u2013 sako dr. R. Stonys.<\/p>\n
Naujoji Civilin\u0117s in\u017einerijos mokslo centro \u012franga bus prieinama ne tik akademinei bendruomenei, bet ir verslui: \u012fmon\u0117s gal\u0117s tikrinti savo produkt\u0173 stabilum\u0105, kurti med\u017eiag\u0173 alternatyvas ir grei\u010diau \u012fgyvendinti prototip\u0173 vystymo procesus.<\/p>\n
Pasak dr. Rimvydo Stonio, naujasis prietaisas sustiprins mokslo ir verslo bendradarbiavim\u0105 kuriant tvarias, ilgaam\u017ees med\u017eiagas ir auk\u0161tos prid\u0117tin\u0117s vert\u0117s produktus bei u\u017etikrins toki\u0173 produkt\u0173\u00a0 efektyvum\u0105 ir ekologi\u0161kum\u0105.<\/p>\n
Naujoji technologija tur\u0117s plat\u0173 pritaikym\u0105 statybos, energetikos ir kitose pramon\u0117s srityse, o VILNIUS TECH planuoja ir toliau aktyviai jungtis prie \u012fvairi\u0173 tarptautini\u0173 partnerys\u010di\u0173.<\/p>\n
Neseniai VILNIUS TECH Civilin\u0117s in\u017einerijos mokslo centras u\u017e 300 000 eur\u0173 \u012fsigijo \u012frang\u0105, skirt\u0105 ilgalaikiams, pa\u017eangiems gel\u017ebetonio tyrimams. Jiems bus naudojami modern\u016bs ilgalaik\u0117s apkrovos stendai su nuolatiniu monitoringu, o visas eksperimentas truks ne ma\u017eiau nei vienerius metus specialiai tam pritaikytoje kameroje su temperat\u016bros ir dr\u0117gm\u0117s reguliavimo funkcija.\u00a0<\/p>\n
Paprastai in\u017einerin\u0117je praktikoje bandymai atliekami po 7, 28 ar 56 par\u0173, tad tyrimai, trunkantys ilgiau nei 56 paras, yra tikra retenyb\u0117. Tai leis mokslininkams gauti itin verting\u0173 ilgalaik\u0117s elgsenos duomen\u0173, kurie leis geriau projektuoti gel\u017ebetonines konstrukcijas ir atsi\u017evelgti \u012f tvarumo principus.\u00a0<\/p>\n
