Title (EN) MANUFACTURING PROCESS OF SHAPED MODELS AND DEVICES
(FR) PROCEDE DE FABRICATION DE MODELES ET DE DISPOSITIFS FACONNES
Abstract: front page image
(EN)Manufacturing process of durable shaped models and devices consisting of mixing a liquid binding composition made of phenolic resin and poly-isocyanate, on the one hand with an inert filler, such as gypsum, pulverulent schist, ball bearing dust, sand, metal powder, granulated aluminium, quartz sand, swelling clay, glass or wood fibres, and on the other hand with a pyridinic compound acting as an accelerator. This process is essentially used for shaping models, moulded cores, as well as moulded plates. such as those shaped by joineries specialized in the preparation of models. According to this process, it is also possible to manufacture moulded objects having dielectric properties.
(FR)Procede de fabrication de modeles et de dispositifs faconnes durables consistant a melanger une composition liante liquide, faite de resine phenolique et de poly-isocyanate, d"une part avec une charge inerte, telle que gypse, schiste pulverulent, poussiere de roulement a billes, sable, poudre metallique, grenaille d"aluminium, sable de quartz, argile gonflante, fibres de verre ou bois, et d"autre part avec un compose pyridinique, ce dernier faisant fonction d"accelerateur. Le procede sert essentiellement a faconner des modeles, des noyaux moules, ainsi que des plaques moulees, tels qu"ils sont faconnes par les menuiseries specialisees en preparation de modeles. Selon ce procede il est egalement possible de fabriquer des objets moules presentant des proprietes dielectriques.
