Chemical mechanical pulping yog ib txoj kev pulping uas siv tshuaj pretreatment thiab mechanical sib tsoo tom qab kho.Ua ntej, ua me ntsis pretreatment (dipping los yog ua noj) nrog tshuaj kom tshem tawm ib feem ntawm hemicellulose los ntawm ntoo chips.Lignin tsawg los yog yuav luag tsis yaj, tab sis cov txheej intercellular yog softened.Tom qab ntawd, lub disc zeb yog siv rau kev kho mob tom qab zom cov ntoo chips (los yog nyom chips) cais cov fibers rau hauv cov ntaub so ntswg, uas yog hu ua chemical mechanical pulp (CMP).
Ob chav ntsia hlau knotter tshuab muaj feem xyuam rau qhov ntxhib pulping ntawm ntoo chips, xyoob chips, ceg ntaub ntawv, nplej straw thiab lwm yam ntaub ntawv raw.Nws tuaj yeem ncaj qha ua cov ntaub ntawv raw rau hauv velvet fibers, thiab tuaj yeem ua ncaj qha rau hauv cov ntaub so ntswg nrog siab concentration refiners.
Ob chav ntsia hlau knotter tshuab yog tsuas yog tsim los ntawm slurry chamber, lub hauv paus, pub khoom noj, kis tau tus mob, lub ntsiab lub cev muaj zog, thiab lwm yam. nyob rau hauv velvet fibers nyob rau hauv lub zog rubbing thiab sib tsoo ntawm lub phaj sib tsoo.Lub tshuab muaj cov qauv yooj yim, yooj yim installation thiab yooj yim txij nkawm.
