Ushbu manbaada yer osti qatlamidan qazib olingan gazlar tarkibini oʻrganish asosida oltingugurt mavjudligi hamda uning miqdoriga bogʻliq holda tozalash usuli tanlangan. Bunda absorbsion usul tanlanib, unda ishlatiladigan absorbentlarning qoʻllanilishi texnologik tizimi qisman bayon qilingan. Shu jumladan ushbu oltingugur birikmasi boʻlgan H₂S ning hosil boʻlishi, uning umumiy ma’lumotlari va sharxi, zararli ta’siri hamda unga nisbatan eng yuqori sezuvchanlikka ega bo‘lgan kasallik turlarining ayrimlari haqida qisman ma’lumotlar keltirilgan.

ПОЛУЧЕНИЕ БРИКЕТОВ С ИСПОЛЬЗОВАНИЕМ СВЯЗУЮЩИХ ИЗ МЕСТНОГО СЫРЬЯ И ОТХОДОВ.

В статье показано влияние наполнителей на прочностные свойства угольных брикетов. Показано, что увеличение прочности тем, что в присутствии наполнителя происходит сшивание соседних частиц наполнителя в структуре угольного брикета макромолекулами ингредиентами композиционного материала. В результате между частицами наполнителя появляются мостики индивидуальных цепочек макромолекул, что способствует ограничению числа возможных конформаций макромолекул и их сегментного движения, что приводит к повышению прочности брикета.

As you know, ischemic brain damage is increasing all over the world. According to the WHO, cardiovascular disease (CVD) is the leading cause of death worldwide. 17.5 million people die from CVD every year.

DEPENDENCE OF ITS PHYSICAL AND CHEMICAL PROPERTIES ON THE STRUCTURE OF BRIQUETTES

2024-11-20T08:31:13-07:00

The article discusses the main properties of organic and inorganic ingredients for the production of coal briquettes from local raw materials and production waste. The structure and properties of these ingredients have been studied. It is shown that all ingredients play a major role in the development of coal briquettes.Gossypol resin, which is a binder for coal briquettes, has a more complex composition, which includes compounds with different functional groups: aldehydes, ketones, carboxylic acids, alcohols, etc. Therefore, it meets the requirements: it has high adhesive properties, relative environmental safety, quickly hardens, has a high calorific value, and is not in short supply
