Abstract

RETROCOLA RÍGIDA PARA EVITAR ONDULAÇÃO DE DISCOS DE FIBRA. Sistemas e métodos incluem fornecer um artigo abrasivo revestido com um substrato formado com uma pluralidade de fibras higroscópicas, uma camada abrasiva compreendendo a revestimento de constituição, a revestimento de encolamento, a revestimento de superencolamento ou combinações dos mesmos dispostos em um primeiro lado do substrato, e uma camada antiondulação disposta em um segundo lado do substrato. A camada antiondulação à base de polímero permite o artigo abrasivo revestido alcançar uma mudança de ondulação entre -5 milímetros e 25 milímetros, a mudança de ondulação sendo expresso como a ondulação do artigo abrasivo revestido em milímetros a 90% de umidade relativa menos a ondulação do artigo abrasivo revestido em milímetros a 20% de umidade relativa. O artigo abrasivo revestido não exibe perda substancial de desempenho de moagem, impulso de velocidade ou uma combinação dos mesmos quando comparados a artigos abrasivos revestidos livres da camada antiondulação.
