Abstract
Prezenta inventie se refera la o compozitie pentru creion termoindicator de viraj la 150+5 degree C utilizat la controlul temperaturii în lucrari de sudura si în anumite parti ale unor instalatii reactoare si conducte. Compozitia pentru creionul termoindicator de 150-5 degree C este constituita din : complex tiocianic al nichelului cu utropina ca substanta termosensibila carbonat de calciu ca material de umplutura si amestec de parafina cu reziduu de polietilena calianti. Creionul termoindicator de 150-5 degree prezinta un viraj de culoare de la vernil la oliv în timp de 2 sec.BACKGROUND OF THE INVENTION The present invention relates to a composition for a 150 + 5 degree C thermostatic pencil used to control temperature in welding works and in certain parts of reactor and pipe installations. The composition for the 150-5 ° C thermowell pen is constituted by: the thiocyanate of nickel with utropine as the calcium carbonate thermosensitive substance as a filler material and a blend of paraffin with a polyethylene residue. The 150-5 degree thermo-indicating pin shows a color turn from vernil to oliv in 2 sec.
