Abstract
1980. gadā kosmosa stacijā “Salūts” pirmoreiz kosmonautikas vēsturē tika realizēts putupoliuretāna ieguves eksperiments mikrogravitācijas apstākļos, kura rezultāta tika iegūtas jaunas atziņas par ķīmiski tehnoloģisko procesu norisi kosmosā. Kosmosā tapa Maskavas olimpisko spēļu simbola lācīša figūra. Iekārtu "Lotoss", kas pašreiz atrodas Latvijas Ķīmijas vēstures muzeja krājumā, LPSR Zinātņu Akadēmijas Koksnes ķīmijas institūtā izstrādājis latviešu ķīmiķis, ķīmijas doktors, izgudrotājs un gleznotājs Arnolds Alksnis, un tā domāta polimerizācijas reakciju pētīšanai bezsvara stāvoklī.
n 1980, for the first time in the history of cosmonautics, an experiment of extraction of polyurethane foam under microgravity conditions was carried out at the space station “Salūts”, as a result of which new insights into the course of chemical technological processes in space were obtained. A teddy bear symbol of the 1980 Moscow Olympic Games was created in space. The device "Lotoss", which is currently in the collection of the Latvian Chemistry History Museum, was developed by Latvian chemist, inventor and painter Arnolds Alksnis at the Institute of Wood Chemistry of the Latvian SSR Academy of Sciences, and is intended for studying polymerization reactions in weightless state.
