Koj ntsuas dej noo li cas hauv ntawv / ntoo pulp?
Daim ntawv tsis yog rau cov ntaub ntawv sau xwb. Nws yog siv rau hauv cov ntaub so ntswg, cov khoom siv hauv chav ua noj (xws li phaj, tais thiab khob), thiab tseem nyob hauv cov thawv ntawv thiab cov raj. Vim tias muaj ntau yam khoom uas muaj peev xwm ua tau los ntawm cov ntawv, cov neeg tsim khoom yuav tsum muaj cov txheej txheem ua haujlwm kom ua tau raws li lub voj voog no.
Ib yam li cov neeg tsim qoob loo thiab cov qoob loo lossis cov neeg soj ntsuam hauv tsev yuav tsum tau paub tas li ntawm cov dej noo ntawm cov ntaub ntawv uas lawv siv, yog li ua cov ntawv tsim tawm. Nws tsis tuaj yeem hais tau tias nws tseem ceeb npaum li cas kom paub ntau npaum li cas dej hauv koj cov khoom thiab yuav ua li cas rau nws thaum nws tiav, los ntawm kev siv lub hygrometer ntawm txhua kauj ruam ntawm cov txheej txheem tsim khoom - raws li koj tau twv.
Qee daim ntawv ya raws ntsuas siv tus pins thiab cov yam ntxwv tiv thaiv hluav taws xob los ntsuas cov dej noo ntawm daim ntawv pulp. Cov ntsuas no muaj txiaj ntsig zoo rau kev tshuaj xyuas phau ntawv ntawm cov khoom siv ntawv. Txawm li cas los xij, muaj lwm hom electrodes uas tuaj yeem siv los ntsuas cov dej noo ntawm daim ntawv.
Thaum lub sij hawm ua daim ntawv, qee cov ntawv ntsuas dej tsis siv tus pin los ntsuas cov dej noo ntawm cov ntaub so ntswg ntawm cov ntaub so ntswg, tab sis siv cov electrode tshwj xeeb nrog lub taub hau sib cuag (xws li Delmhorst's 12-E electrode). Cov taub hau tshwj xeeb no tso cai rau lub ntsuas ntsuas kom nyeem cov dej noo ntawm cov tawv nqaij ntawm txoj kab yam tsis muaj kev txwv ntau lawm.
Yog tias muaj dej noo ntau dhau ntawm cov tawv nqaij thaum nws dhau los ntawm cov txheej txheem muab, daim ntawv yuav poob sib nrug.
Qhov tseem ceeb ntawm kev ntsuas % MC hauv ntawv txuas mus rau qhov tseeb tias cov dej noo tuaj yeem cuam tshuam rau kev ua tau zoo ntawm cov cuab yeej koom nrog hauv cov txheej txheem papermaking.
Ntsuas noo noo nyob rau hauv pulp thiab ntawv
Txij li cov dej noo nyob rau hauv daim ntawv tuaj yeem yog qhov ua rau-lossis-tawg nyob rau hauv qhov kawg ntawm cov khoom zoo, kev siv thev naus laus zis los xyuas kom meej tias cov qib noo noo yog qhov tseem ceeb heev. Delmhorst muaj ob daim ntawv ntsuas dej: RDM-3P thiab P-2000.
Cov ntsuas dej noo no ua rau muaj kev sib cuag ncaj qha nrog ntau yam khoom tsim nyog rau cov duab los qhia, corrugated thiab ntawv raj, thiab muaj peb qhov sib txawv rau kev ntsuas dej tshwj xeeb.
Khaws daim ntawv zoo hydrated
Muaj lwm yam khoom siv uas tsis tuaj yeem nqa tau los ntsuas dej noo hauv cov ntawv thiab cov khoom ntoo. Tsis tas li ntawd, muaj qee qhov kev ceev faj uas koj tuaj yeem ua kom koj cov khoom siv tam sim no ntawm cov dej noo zoo.
Piv txwv li, thaum cov ntawv xa khoom tuaj rau hauv, qhov chaw ntawm kev xa khoom yuav tsum tau txiav txim siab. Daim ntawv yuav tsum muaj sij hawm los kho qhov kub thiab txias, tshwj xeeb tshaj yog tias nws qhib ntawm no.
Txhawm rau kom tswj tau qhov kub thiab txias, nws tseem pom zoo kom tsis txhob muab daim ntawv tso rau hauv cov chaw uas muaj cov cua sov nyob ze lossis cov khoom siv txias txias, vim tias cov cuab yeej no tuaj yeem cuam tshuam rau daim ntawv txoj kev ua kom zoo. Thaum lub sij hawm cov txheej txheem tsim ntawv, cov ntawv ntim yuav tsum tau muab qhwv kom txog thaum nws xav tau kev ua tiav - tsis muaj sij hawm ntxiv yuav tsum tsis txhob siv.
Thaum kawg, kev siv cov ntawv pov thawj vapor-pov thawj yog pom zoo. Siv cov wrappers ntawm cov ntawv tsim cov kauj ruam yuav pab cov ntawv nyob ruaj khov thiab tshiab thaum khaws cia ntau dhau, tsis xav ya raws deb ntawm cov khoom kawg.
