Yam cuam tshuam rau pulping
Muaj ntau yam uas cuam tshuam rau pulping, xws li pulping siab, riam qhov sib nrug, lub sijhawm pulping, pulp concentration, pulp zog, riam yam ntxwv, pulping kub, ntawv pH thiab additives, thiab lwm yam. Kev hloov pauv hauv ib qho yuav tsis tsuas yog cuam tshuam rau lwm yam, tab sis kuj cuam tshuam rau qhov zoo, tso zis thiab lub zog siv ntawm pulping. Txhawm rau tsim cov txheej txheem pulping tsim nyog, nws yog ib qho tsim nyog los tham txog ntau yam no. Ntawm lawv,Polyester Plain Woven Mesh Belt, raws li cov khoom tseem ceeb hauv cov txheej txheem kev thauj mus los, nws cov kev ua haujlwm ruaj khov yuav cuam tshuam ncaj qha rau kev txuas ntxiv thiab kev ruaj ntseg ntawm cov txheej txheem pulping.
(1) Pulping siab thiab riam sib nrug
Lub siab exerted rau ntawm chav tsev pulp-kos duab cheeb tsam hu ua lub pulp-kos duab tshwj xeeb siab. Nws cov qauv yog raws li nram no:
P=
Nyob rau hauv cov mis, p ---- lub pulp siab thaum sib tsoo, Pa;
F ---- lub siab nruab nrab ntawm qhov sib tsoo disc cheeb tsam lossis cov riam ya ntawm lub pulper thiab hauv qab riam, N;
A ---- thaj chaw sib cuag ntawm thaj chaw sib tsoo lossis cov riam ya ntawm lub pulper thiab hauv qab riam, m²
Lub pulp beating siab yog qhov tseem ceeb tshaj plaws txiav txim siab qhov ua tau zoo ntawm cov txheej txheem ntaus. Kev txiav txim siab ntawm cov pulp beating siab yog qhov tseem ceeb rau kev ua kom zoo ntawm kev ntaus, ua kom lub sijhawm ntaus, thiab txuag lub zog noj. Nyob rau hauv ib txoj kab nruam ntaus ntau lawm, Polyester Plain Woven Mesh Belt yog lub luag haujlwm rau kev thauj mus los ua ntej -kho pulp mus rau cov khoom ntaus. Kev tswj ceev thiab nro ntawm txoj siv no yuav tsum tau ua kom haum nrog kev hloov ntawm kev sib tsoo lub siab kom tsis txhob muaj cov ntaub qhwv los yog cov khoom tsis txaus, uas yuav cuam tshuam rau kev ruaj ntseg ntawm lub siab.
Qhov luaj li cas ntawm qhov sib tsoo siab piv yog ze ze rau qhov kev ncua deb ntawm cov riam. Vim tias muaj cov txheej slurry nyias ntawm cov menyuam riam thiab cov riam hauv qab, qhov tsawg kawg ntawm rab riam yuav tsum tau khaws cia ntawm 0.05 txog 0.08 hli. Yog hais tias cov hniav ncaj qha hu rau riam nto, piv txwv li, tsis muaj slurry txheej, tsis tsuas yog cov beating nyhuv yuav ploj, tab sis cov hniav riam kuj yuav hnav. Qhov tseeb, rab riam ya yuav tsum tsis txhob ua kom tiav nrog rab riam hauv qab. Nws yog tsim nyog sau cia tias qhov pom tseeb ntawm Polyester Plain Woven Mesh Belt yuav cuam tshuam rau cov ntsiab lus impurity ntawm slurry nkag mus rau hauv cov txheej txheem ntaus. Cov impurities ntau dhau yuav ua rau muaj qhov txawv txav ntawm qhov sib txawv ntawm rab riam, yog li cuam tshuam rau kev ruaj ntseg ntawm kev sib tsoo siab piv.
Kev nce qhov sib piv siab yog qhov zoo rau kev txiav fiber ntau. Qhov ceev pulping ceev ua rau kev txiav ntau dua thiab ntau dua crushing, thaum feem pua ntawm cov fibers tsis zoo txo.
Yog li ntawd, thaum ua dawb- ntws slurry, rab riam yuav tsum tau txo kom sai, thiab lub siab tshwj xeeb yuav tsum tau nce. Ua ntej cov pob khoom fiber ntau yog o, siv lub siab kub kom txiav cov fibers sai. Hloov pauv, thaum ua cov kua nplaum nplaum, cov riam nrug yuav tsum tau maj mam txo, qhov tshwj xeeb siab yuav tsum tau maj mam nce, thiab cov fibers yuav tsum tau o tag nrho thiab finely fibrillated nyob rau lub sij hawm ntev nrog lub siab. Thaum lub sijhawm ua haujlwm no, Polyester Plain Woven Mesh Belt yuav tsum muaj kev tiv thaiv corrosion zoo heev thiab hnav tsis kam ua kom tau raws li lub sijhawm ntev - kev thauj mus los rau cov khoom sib txawv (xws li acidic thiab alkaline slurries).
Kev ua kom lub siab ntawm lub siab nyob rau hauv ib qho kev sib tw tsis yog tsuas yog ua rau muaj kev siv hluav taws xob ntau ntxiv tab sis kuj tseem ua rau lub sij hawm luv luv (rau kev sib tw ntaus) lossis nce kev ntaus kis las (rau kev ntaus nruam), yog li ua rau cov zis ntau ntxiv thiab txo cov khoom siv hluav taws xob hauv ib chav tsev. Yog li ntawd, hauv kev tsim khoom, thaum ua kom cov khoom lag luam zoo, cov cuab yeej siv yuav tsum muaj peev xwm ua kom muaj peev xwm ua kom tau raws li qhov yuav tsum tau ua ntawm txoj kev ntaus thiab siv tag nrho cov cuab yeej lub peev xwm kom ua tiav kev siv hluav taws xob tsawg.
Hauv kev tsim khoom, qhov tshwj xeeb siab yog tswj los ntawm kev ntsuas lub cev muaj zog tam sim no. Lub siab load ntawm lub cev muaj zog qhia tau hais tias lub siab tshwj xeeb. Lub cylindrical pulper siv lub siab ntawm kev tswj dej siab gauge los yog huab cua siab ntsuas los tswj lub siab thov rau pulping. Tsis tas li ntawd, tsis tu ncua xyuas cov txheej txheem kev khiav hauj lwm ntawm Polyester Plain Woven Mesh Belt thiab kho nws qhov nro raws sij hawm kuj yog ib qho tseem ceeb rau kev tswj xyuas kom ruaj khov ntawm cov pulping tshwj xeeb siab.
