Abstract

POSTUPAK ZA PROIZVODNJU MATERIJALA PLOČASTIH I RAVNIH FILTERA, naznačen time, što se poluproizvod priprema od odpadnih predivnih vlakana pamuka, lana ili konoplje u količini od 1-50 mas.%, prečišćene drvene celuloze koja sadrži više od 92 mas% alfaceluloze i izbeljene papirne celuloze u količini od 5-98 mas.% i zatim se isitni do stepena mlevenja od 22-24В° SR, posle čega se doda kalcinovana diatomejske zemlja u količini 1-45 mas.%: smeša se homogenizuje i doda se 0,3-1,5 mas.% poliamid epoksida ili poliamid poliamin-epihlorhidrin bitumena, tako da odnos prečišćene drvene exeluloze i izbeljene papirne celuloze bude 1:1 do 4:1 smeša se dalje preradjuje na mašini za proizvodnju papira.
