Feem ntau, cov dej dawb los ntawm cov mesh yog siv rau slurry dilution, uas tsis tsuas yog txuag dej, tab sis kuj recycles me me fibers, fillers thiab tshuaj nyob rau hauv cov dej dawb. Rau cov tshuab ntawv uas xav tau cua sov ntawm cov pulp molding slurry, rov siv cov dej dawb kuj tuaj yeem txuag hluav taws xob.
Lub dilution ntawm lub tshuab tshuaj ntsuam teb feem ntau siv ob -theem dilution txoj kev. Hauv thawj theem, cov slurry concentration yog diluted mus rau 0.5-0.6%, thiab cov pulp yog molded rau purification thiab tshuaj ntsuam, thiab ces ntxiv diluted mus rau lub on-line concentration nyob rau hauv lub taub hau ruaj khov lub thawv ua ntej mus rau hauv internet.
Raws li rau lub tshuab tshuaj ntsuam teb, vim yog qhov yuav tsum tau ua ntawm cov yam ntxwv ntawm lub tshuab pulp moulding ntawv, qhov online concentration tsuas yog 0.1-0.3%. Yog tias kev lim dej thiab kev tshuaj ntsuam xyuas tau ua tiav ntawm qhov kev xav tau zoo li no, cov slurry txaus tus nqi ntawm cov purification thiab tshuaj ntsuam xyuas cov cuab yeej yog khi kom loj, ua kom purification tus naj npawb ntawm cov khoom siv tshuaj ntsuam tau nce tshwj xeeb, tsis yog vim kev nqis peev loj, thaj chaw loj, thiab cov kav dej sib txawv, tab sis kuj siv lub zog loj.
Nws tuaj yeem pom tau tias kev ua haujlwm ntawm pulp molding dilution yog ib qho haujlwm tseem ceeb heev. Hauv kev tsim khoom, nws yuav tsum tau ua tib zoo saib xyuas cov kev hloov pauv hauv cov concentration ntawm diluted slurry thiab tswj nruj me ntsis kom ntseeg tau tias kev ruaj khov ntawm kev tsim khoom; kuj xyuam xim rau cov kev hloov ntawm cov khoom zoo thiab kev ua haujlwm, thiab hloov cov concentration ntawm diluted slurry thaum tsim nyog. , Kom kov yeej cov teeb meem xws li cov saum toj no.
Rau lub tshuab hluav taws xob Fourdrinier, raws li cov yam ntxwv ntawm lub tshuab moulding slurry, cov khoom siv ntawm cov ntawv tshuab thiab cov kev xav tau zoo ntawm daim ntawv tiav, qhov concentration ntawm ntawm -kab slurry yog 0.3-1.0%. Lub sijhawm no, cov℃ntawm dilution ntawm slurry yog roughly tib Lub slurry muaj tib yam ntawm -kab concentration, uas yog, tib slurry concentration yog siv rau purification, tshuaj ntsuam thiab on-line sib sau.
