麦草制取低污染的SCMP和CTMP的研究
Title:ResearchonLow-PollutionSCMPandCTMPProductionfromWheatStraw
Introduction:
Inrecentyears,therehasbeenagrowingconcernaboutenvironmentalpollutioncausedbythepulpandpaperindustry.Asaresult,studieshavefocusedondevelopingmoreeco-friendlyandsustainablemethodsforpulpproduction.Oneapproachinvolvesutilizingagriculturalresiduessuchaswheatstrawtoproducepulpwithlowpollution.Thispaperaimstoexploretheproductionoflow-pollutionSemi-ChemicalMechanicalPulp(SCMP)andChemi-ThermoMechanicalPulp(CTMP)fromwheatstraw.
Background:
SCMPandCTMParewidelyusedinthepulpingindustryduetotheirexcellentpapermakingproperties.SCMPisproducedthroughacombinationofchemicalandmechanicalprocesses,whileCTMPisprimarilyamechanicalprocesswithsomechemicaltreatment.Traditionalpulpingprocesseshaveaconsiderableimpactontheenvironmentduetotheuseofharshchemicalsandhighenergyconsumption.Byutilizingwheatstraw,arenewableandwidelyavailableresource,wecanminimizepollutionanddecreasethedependenceontraditionalwood-basedpulpingmethods.
