Abstract

U radu su navedeni neki materijali koji se koriste za izradu mikroreaktora. Među njima se nalaze polimeri, keramika, staklo te metali. Navedena su fizikalna, mehanička i toplinska svojstva te kemijska reaktivnost odnosno inertnost. Kemijska obilježja bitna su zbog toga što nam ukazuju na to koji materijal je najbolje upotrijebiti ukoliko imamo agresivne reaktante. U uvodu kratko je objašnjen koncept budućih postrojenja koja bi primjenjivale mikroreaktore za sintezu kemijskih spojeva koje koristimo u svakodnevnom životu. Fizikalna i mehanička svojstva nam govore o izdržljivosti materijala na temperaturu i samoj kvaliteti materijala te gustoći. Toplinska nam svojstva govore o razini deformacije mikrostruktura uslijed povećanja temperature. Toplinska vodljivost nam govori kako brzo se materijal može riješiti topline generirane kemijskom reakcijom, odnosno koliko brzo može sustav nadoknaditi izgubljenu toplinu iz okoline. Najbitniji materijal za izradu mikroreaktora je staklo, nakon toga slijede polimerni materijali koji se često koriste kao materijal za izradu mikrostruktura.

Abstract (english)

In this paper materials used for production of microreactors are discussed. Amongst these materials are glass, ceramics, polymers and metals. Physical, mechanical, thermal properties and chemical reactivity or inertness are listed. Chemical properties of materials for microreactors are important because they point out the material that is best used if aggressive reactants are used. In the introduction the concept of future plants that use microreactors for the synthesis of chemical compounds used in everyday life are explained. Physical and mechanical properties tell us about the durability of materials towards the temperature, the quality of the material and density. Thermal properties tell us about the level of deformation microstructure due to increases in temperature. Thermal conductivity tells us how fast the material can exchange the heat generated by a chemical reaction, and how well the system can quickly make up for the lost heat from the environment. The most important materal used for production of microreactors is glass, after that polymeric materials, which are often used as materials for the microstructures.
