APapel Tangará, fábrica que atua no<br />

segmento tissue em Santa Catarina,<br />

apostou em uma novidade. Ela pode<br />

ser resumida a uma cobertura cerâmica<br />

perfurada, desenhada especialmente<br />

para caixas de sucção de feltro:<br />

o IBS-pressMaster. O objetivo da Tangará era obter<br />

melhor rendimento do condicionamento de feltro,<br />

um processo que, até então, tomava tempo e recursos<br />

da fábrica.<br />

Originalmente, a empresa trabalhava com uma<br />

cobertura formada por réguas e ranhuras transversais.<br />

Assim que instalaram a cobertura de design<br />

perfurado “pressMaster”, perceberam uma mudança<br />

significativa no condicionamento do feltro, garantindo<br />

um melhor tempo de permanência do feltro sob<br />

ação de vácuo: fabricado em revestimento cerâmico<br />

feito de óxido de zircônio, material cerâmico com<br />

menor rugosidade. “No design perfurado temos uma<br />

área aberta maior, o que permite um controle mais<br />

homogêneo do processo e uma drenagem mais suave”,<br />

explica o diretor da IBS, Vanderlei Santos Silva.<br />

O sócio-proprietário da Papel Tangará, Sidney<br />

Melotti, surpreendeu-se com o produto; ele afirma<br />

que houve um aumento de 20% da vida útil<br />

do feltro desde sua instalação. “A função do feltro<br />

é retirar a água do papel, por isso ele fica sempre<br />

tensionado e, com o tempo, vai se fechando. Além<br />

apel Tangará, a paper mill that produces tissue<br />

in the State of Santa Catarina, bet on innovation,<br />

which can be summarized as a drilled ceramic<br />

cover, specially designed for felt suction boxes:<br />

the IBS-pressMaster. The goal of Tangará was to<br />

obtain better felt conditioning performance, a process that,<br />

up to now, took time and resources from mill operations.<br />

Initially, the Company worked with a cover formed<br />

by transverse edges and grooves. As soon as the “press-<br />

Master” drilled design cover was installed, the Company<br />

perceived a significant change in felt conditioning, ensuring<br />

better felt permanence times under vacuum: manufactured<br />

with a ceramic coating made from zirconium oxide,<br />

creating a ceramic material with greater smoothness. “Due<br />

to the drilled design, there is a larger open area, which<br />

allows a more homogeneous process control and smoother<br />

drainage,” explains Vanderlei Santos Silva, Director of IBS.<br />

Sidney Melotti, Owner/Partner of Papel Tangará, was<br />

surprised by product performance; he states that there<br />

has been a 20% increase in felt life since its installation.<br />

“The function of the felt is to remove the water from the<br />

paper, so it is always under tension and, over time, closes.<br />

Besides, fibers and other chemicals are deposited in the<br />

pores of the felt, with the correct conditioning, that is, a<br />

vacuum being applied, they remain open for longer, and<br />

thus reduces the use of cleaning chemicals,” explains Mill<br />

Owner Melotti.<br />

Also, as to cleaning, before, every five days, the mill<br />
