MAQOLA ANNOTATSIYASI

quote
Maqolada pataklar va qo‘yma pataklarining asosiy maqsadi hamda funksional ahamiyati, shuningdek ularni ishlab chiqarishda qo‘llaniladigan materiallarga qo‘yiladigan asosiy talablar aniqlangan. Pataklar tuzilishi, materiali va qalinligining poyabzalning issiqlik o‘tkazuvchanligi hamda umumiy issiqlik izolyatsiyasi xususiyatlariga ta’siri ko‘rib chiqilgan. Alohida e’tibor pataklardagi ko‘p qatlamli tuzilmaning issiqlik himoyasi bilan qatlamdagi biriktirilgan materiallari qalinligi o‘rtasidagi bog‘liqlikka qaratilgan. Tadqiqotda materiallarni to‘g‘ri tanlash va qatlam qalinligini optimallashtirish turli iqlim sharoitlarida oyoq qulayligini ta’minlashda hal qiluvchi omil ekani ta’kidlangan. Tajriba natijalari shuni ko‘rsatdiki, an’anaviy qo‘llaniladigan poyabzalning pastki qismidagi material qatlamlari faqat dastlabki kiyish davrida, ya’ni atrof-muhit harorati –5,0°C dan –19,9°C gacha bo‘lgan holatlarda yetarli darajada qulaylik beradi. Ammo –25°C va undan past haroratlarda bu materiallar samaradorligini yo‘qotadi, bu esa poyabzal konstruktsiyasida termoizolyatsiya texnologiyalarini takomillashtirish zarurligini ko‘rsatadi.
