A method of treatment of resin impregnated manufactured paper to render the paper fire retardant, said method comprising the addition of a fire retardant compound containing borax and diammonium phosphate introduced into the paper. It is an objective of the invention that the fire retardant system ameliorates any degradation of desirable physical characteristics of the fibrous materials. In particular, the characteristics of wicking and liquid retention should not be unduly degraded when the base material is a “wickable” paper. It is a further objective that the fire retardant systems of embodiments of the present invention not be significantly degraded when the resin treated fibrous material is continuously immersed in running water.

摘要:
A thin fluoropolymer film is covalently bonded to a microporous ptfe film to make a bilayer for separation, filtration or reverse osmosis, by exposing the microporous film to perfluorocyclohexane under plasma. The perfluorocyclohexane molecules undergo scission and the fragments combine on the substrate to make a fluoropolymer film wherein the pores of the substrate have not been completely closed by the coating.
