Mis on tselluloosi vahutamisvahend ja muu vahutamismeetod<\/h1>\n

Vahtude kontroll on tselluloosi ja paberi t\u00f6\u00f6tlemise peamine v\u00e4ljakutse. Kui vaht j\u00e4\u00e4b kontrollimatuks, v\u00f5ib see tekitada ohutus- ja tootmisprobleeme, nagu muda \u00fclevoolamine, pumba t\u00f5hususe v\u00e4henemine ja halb vee filtreerimine. Defoamer aitab neid probleeme v\u00e4hendada, k\u00f5rvaldades liigse vahu mustalahuse pesemisest, tselluloosi pesemisest, s\u00f5elumisvalgendamisest ja muudest protsessidest.<\/p>\n

Vahu\u00e4rastusvahend<\/h2>\n

Vahtude haldamine kaasaegsetes paberi- ja vormitud kiudude tehastes on v\u00e4ga oluline, et v\u00e4ltida mitmesuguseid kvaliteedi-, t\u00f6\u00f6- ja tootmisprobleeme. Vaht v\u00f5ib h\u00e4irida seadmete t\u00f5husust, p\u00f5hjustada paberimassi pleegituskemikaalide kadusid ja p\u00f5hjustada keskkonnavastutusn\u00f5udeid; vahutamisvahendid pakuvad lahendust, peatades vahumullide tekkimise paberitootmisprotsessi ajal.<\/p>\n

Keemilise tselluloosi tootmisel kasutatav mustalahus kipub t\u00f6\u00f6tlemise k\u00e4igus vahtu moodustama, mis v\u00e4hendab protsessi t\u00f5husust ja masinate kasutegurit. Seet\u00f5ttu tuleb vahu eemaldamise ja vahutamisvastaseid aineid kasutada, et v\u00e4hendada vahu moodustumist ja parandada paberi kvaliteedi tootmist.<\/p>\n

K\u00e4esoleva leiutise koostised v\u00f5ivad kergesti dispergeeruda t\u00e4iendavas vees, segades kontsentreeritud toodet \u00f5rnalt sobiva temperatuuriga veega; see annab m\u00e4rkimisv\u00e4\u00e4rseid eeliseid v\u00f5rreldes teatavate varasemas tehnikas kasutatavate vahutamisvahenditega, mille lahustamiseks k\u00f5vas veekeskkonnas on vaja ulatuslikku segamist ja kuumust. Lisaks sellele on nende koostised \u00e4\u00e4rmiselt stabiilsed anorgaaniliste soolade, n\u00e4iteks kaltsiumkarbonaadit\u00e4itematerjalide suhtes - eelis on eriti oluline, kuna paljud paberisordid sisaldavad neid m\u00e4rkimisv\u00e4\u00e4rses koguses.<\/p>\n

Vahatusvahendi emulsioon<\/h2>\n

Paberi- ja vormitud kiudainemasinate vahukontroll on oluline kvaliteedi-, t\u00f6\u00f6- ja tootmisprobleemide v\u00e4ltimiseks. Vahtumine v\u00f5ib oluliselt v\u00e4hendada masina t\u00f5husust, v\u00e4hendada paberimassi ja l\u00f5pp-paberi saagist ning suurendada pleegituskemikaalide kasutamist. Vahtumisvastaseid vahendeid ja vahutusvahendeid tuleb kasutada, et k\u00f5rvaldada vahu tekkimine tootmise ajal, k\u00f5rvaldades samal ajal \u00f5humullid protsessi k\u00e4igus.<\/p>\n

Tselluloositehastes kasutatavad vahutamisvahendid on silikoonist ja veest koosnevad \u00f5li-vesi emulsioonid. Tavaliselt koosneb vahutamisvahendaja vesifaasist, mis sisaldab mitteionilisi pindaktiivseid aineid, nagu met\u00fc\u00fclesterne soja\u00f5li v\u00f5i ritsinus\u00f5li v\u00f5i et\u00fcleen(bis)stearamiidvaha; lisaks v\u00f5ib see sisaldada \u00f5li, nagu oleiin- v\u00f5i linaseemne\u00f5li, mille happesust on stabiliseeritud letsitiini v\u00f5i fosfolipiidiga.<\/p>\n

Vahu\u00e4rastusvahendid on t\u00f5husad vahendid paberivabrikutest p\u00e4rineva pruuni laovaru ja heitvee t\u00f6\u00f6tlemiseks. Need on kavandatud nii, et need on t\u00f5husad ka k\u00f5va vee puhul, mis sageli tekitab probleeme vahutamisvahenditele, ning vahutamisvahendid on saadaval erineva kontsentratsiooniga, mida saab otse tselluloosilahusele kanda ja mis on ka mustalahuses lahustuvad.<\/p>\n

Vahatustamise lahus<\/h2>\n

Paberit\u00f6\u00f6stusele m\u00f5eldud vahu\u00e4rastuslahendused pakuvad kulut\u00f5husaid v\u00f5imalusi vahu moodustumise v\u00e4hendamiseks ja olemasoleva vahu purustamiseks, samuti paberimassi pesemise t\u00f5hususe, mustade vedelike juhtimise ja paberitootmise kvaliteedi parandamiseks. Lisaks sellele toimivad vahutamisvahendid h\u00e4sti madalatel temperatuuridel, j\u00e4\u00e4des stabiilseks isegi v\u00e4ga kontsentreeritud reoveevoogudega kokkupuutel; tavaliselt koosnevad need mineraal\u00f5lidest, pol\u00fcdimet\u00fc\u00fclsiloksaanidest v\u00f5i alkoholist\/stearaadist koosnevatest preparaatidest.<\/p>\n

Varasemad vahutamisvahendid ei olnud happelistes tingimustes, eriti k\u00f5vas vees, nii stabiilsed kui soovitud. Kui nende emulsioonid purunevad, kipuvad nad t\u00f5usma mahuti \u00fclaosasse ja v\u00f5ivad ummistada sealt pumpadesse ja seej\u00e4rel paberimasinatesse viivad torud.<\/p>\n

T\u00f5husate vahutamisvastaste ainete valimine on oluline t\u00f5husate paberimassi- ja paberit\u00f6\u00f6tlemisprotsesside, sealhulgas vahu kontrollimiseks. Kvaliteetne vahutamisvastane aine kaitseb selliste kulukate probleemide eest nagu l\u00e4ga \u00fclevool, pumba v\u00e4henenud t\u00f5husus, paberimasinate kehv ladestumine, filtri drenaa\u017eiprobleemid ja vee filtreerimisprobleemid - l\u00f5ppkokkuv\u00f5ttes viib see suurema tselluloosi saagise ja parema tootekvaliteedi saavutamiseni.<\/p>","protected":false},"excerpt":{"rendered":"
