Title
(PT) filme de pvb para visor com projeção ao nível dos olhos, molde de conformação e método de conformação do mesmo
Abstract
(PT)
trata-se de um filme de pvb para hud, um molde de conformação e um método de conformação do mesmo. o erro de precisão de imageamento por hud alcançado pelo filme de pvb para hud é de ± 0,1 mrad. o molde de conformação compreende um molde superior (4) e um molde inferior (5), sendo que os dois podem formar uma cavidade de molde fechada, quando presos em conjunto, em que os filmes protetores são dispostos em superfícies internas do molde superior (4) e do molde inferior (5), respectivamente, para sustentar o material de pvb e evitar que o material de pvb se ligue ao molde superior (4) e ao molde inferior (5), e em que os formatos dos filmes protetores correspondem aos formatos do molde superior (4) e do molde inferior (5). o método de conformação compreende as seguintes etapas: ensanduichar o material de pvb entre dois filmes protetores e, então, colocar o material de pvb em um molde pré-aquecido; ou colocar um primeiro filme protetor, dentre os dois filmes protetores, no molde pré-aquecido e, então, colocar o material de pvb sobre o primeiro filme protetor e, por fim, colocar um segundo filme protetor, dentre os dois filmes protetores, sobre o material de pvb; prender o molde; pressurizar o molde e aquecer o molde a uma temperatura desejada; retirar um filme de pvb conformado em conjunto com os dois filmes protetores; resfriar o filme de pvb conformado; e descamar os dois filmes protetores e obter o filme de pvb para hud.
