Abstract
Inventia se refera la o placa termoizolanta si un procedeu de realizare a acesteia, utilizata în constructii civile si industriale. Placa, conform inventiei, este alcatuita din 80...96% paie de orez în amestec cu 4...20% aschii de lemn, la care se adauga 8...12% atro, fata de aschiile din paiele de orez, rasina formaldehidica si 10% solutie de întaritor compusa din 1,4...1,8 kg/t clorura de amoniu si 0,7...1kg/t solutie de amoniac, care se toarna în forme si se preseaza la o presiune specifica de 2...10 kgf/cm2 si o temperatura a agentului termic cuprinsa între 170...190 degree C, cu 10...30 s/mm de placa finita.The invention relates to a thermo-insulating plate and a process for its realization, used in civil and industrial constructions. According to the invention, the plate consists of 80 ... 96% rice straw mixed with 4 ... 20% wood chips, to which is added 8 ... 12% atro with rice straws, formaldehyde resin and 10% hardener solution consisting of 1,4 ... 1,8 kg / t ammonium chloride and 0,7 ... 1 kg / t ammonia solution, which is poured into molds and pressed under pressure specific gravity of 2 ... 10 kgf / cm2 and a temperature of the thermal agent comprised between 170-190 ° C, with 10 ... 30 s / mm of the finite plate.
