Annotatsiya. Kirish. Vodorod absorberlari uchun materiallarning samaradorligini aniqlashning asosiy mezoni vodorodni saqlash uchun materiallar bir qator oddiy xususiyatlarni qondirishi kerak - uni xona haroratida ko‘p miqdorda ushlab turishi, unchalik yuqori bo‘lmagan haroratlarda tezda chiqarilishi va qulab tushmasligi kerakligi haqidagi yondashuv. Biroq, ehtiyojlarni to‘liq qondiradigan material hali ishlab chiqilmagan. Yangi materiallarni izlash va muammoni hal qilish uchun taklif qilingan turli xil yechimlar so‘nggi bir qator sharh maqolalarida ta’kidlangan. Shu sababli, zeolit tarkibidagi arzon g‘ovakli materialga asoslangan vodorod absorberini ishlab chiqish dolzarbdir.
Usul va materiallar. Ushbu muammoni hal qilishning turli usullari mavjud, ulardan biri kuydiruvchi usuli va polivinilxlor (PVX) dan foydalanishdir. PVXdan foydalanish ma’lum tarkibdagi g‘ovakli keramika ishlab chiqarishning eng iqtisodiy va arzon usuli hisoblanadi. Tadqiqotlarda organik qo‘shimchalar - guruch qobig‘i va PVX ishlatilgan.
Natijalar. Olingan o‘ziga xos sirt maydoni 2500 sm2/g bo‘lgan aluminosilikat tarkibidagi materiallar 100 °C dan 190 °C gacha bo‘lgan harorat oralig‘ida og‘irligi 3 dan 13 og‘irlik % gacha bo‘lgan vodorod absorberlari sifatida ishlatilishi mumkin. .
Xulosa. Tseolit tarkibidagi g‘ovakli keramika asosida yaratilgan absorber yuqori samaradorlikka ega.
