Kev daws teeb meem ntawm cov ntawv tsis xws hauv daim ntawv tshuab tsim thiab xovxwm

Ntu I: Cov ntawv tsis xws luag hauv Cov Ntawv Sau (Hloov Tshooj)

1. Kev tsim tsis zoo, cloudiness/mottling, thiab lub hauv paus nyhav tsis sib xws Ua rau muaj qhov tshwm sim hauv seem tsim: 1. Cov khoom ntim khoom ntim khoom lossis cov kav kav dej, ua rau cov khoom tsis sib xws;

2. Kev qhib qhov tsis sib xws (pem hauv ntej- mus rau -rov qab los yog sab- rau- sab), lossis cov khoom khaws cia thiab clumping ntawm daim di ncauj;

3. Headbox sib xws siab dhau lossis qis dhau; mismatch ntawm Tshuag dav hlau ceev thiab tsim hlau ceev (hnyav ceev sib txawv);

4. Misalignment ntawm lub mis yob los yog tsim ntaub; localized nto irregularities los yog pitting / hnav ntawm cov ntaub;

5. Lub tshuab nqus tsev tsis sib xws ntawm lub tshuab nqus tsev; clogged lub tshuab nqus tsev lub thawv npog; lub tshuab nqus tsev vacuum vim hnav sealing strips;

6. Kev noj tshuaj tsis txaus ntawm cov khoom siv khaws cia lossis flocculants, ua rau fiber ntau flocculation thiab clumping;

7. Kev hloov pauv ntawm cov kua hauv lub taub hau, lub siab tsis ruaj khov, los yog lub zog siab dhau.

 

Cov xwm txheej cuam tshuam rau kev nias nias- teeb meem ntsig txog-xws li hnov ​​​​qhov txhaws lossis qhov tsis sib xws hauv zos dewatering muaj peev xwm- tuaj yeem ua rau "cloudiness" ntau dua (kev tsim tsis sib xws), ua rau cov cheeb tsam nyias nyias tuaj yeem cuam tshuam rau kev sib tsoo. Cov kauj ruam daws teeb meem

1. Kaw lub tshuab mus xyuas daim di ncauj rau cov khoom tsim khoom thiab ntsuas qhov puv - qhov dav dav o

f lub apron board;

2. Ntsuas tus nqi ntws ntawm txhua ceg yeeb nkab thiab tshem tawm cov blockages hauv headbox distributor;

3. Tshawb xyuas lub dav hlau dav hlau ceev, tsim cov xov hlau ceev, thiab lub taub hau sib xws;

4. Tshawb xyuas txhua lub tshuab nqus tsev rau qib nqus, lub hau npog, thiab cov hlua khi;

5. Ua qauv thiab txheeb xyuas cov khoom flocculation, tom qab ntawd kho cov tshuaj ntxiv raws li. 2. Qhov, pinholes, thiab "kab qhov muag" (micro-pinholes)

 

Ua rau Originating hauv Kev Tsim Npuag Tshooj

1. Kev puas tsuaj rau cov ntaub ntawv, xws li cov xov xoob, tawg filaments, lossis ntse protrusions ntawm cov ntaub nto;

2. Cov impurities nyob rau hauv cov ntaub so ntswg, xws li cov tawv nqaij tawg, ua npuas ncauj clumps, slime/decayed pulp, yas strands, los yog hlau khib nyiab;

3. Resin flakes los yog deposits deposits detaching los ntawm lub headbox sab hauv thiab depositing mus rau lub forming ntaub, punctureing lub ntub daim ntawv web;

4. Ua tsis tiav ntawm cov tshuaj ntxuav los yog cov ntxaij vab tshaus siab (vim yog txhaws), tso cai rau cov ntxhib tsis kam ntws rov qab;

5. Lub siab ntau dhau ntawm cov ntaub npuag da dej, ua rau lub siab - lub dav hlau dej ntsoog rau cov ntawv nyias nyias.

 

Cov xwm txheej hnyav hnyav los ntawm Nias Qhov nyob rau hauv daim ntawv ntub dej nthuav dav nyob rau hauv lub siab ntawm cov xovxwm seem, uas ua rau loj, tsis xwm yeem ruptures. Cov kauj ruam daws teeb meem

1. Ua kom pom tseeb ntawm tag nrho cov xaim rau kev puas tsuaj los yog xoob strands (jumpers);

2. Txheeb xyuas qhov tsis lees txais kev ua haujlwm ntawm cov ntxaij vab tshaus thiab cov tshuaj ntxuav hauv txhua ntu;

3. Ntxuav tawm cov resin thiab pulp deposits ntawm lub headbox thiab hlais;

4. Txo cov tshuaj tsuag dej hauv cov kab sib txuas thiab hloov mus rau kiv cua - zoo li tus atomizing nozzles . 3. Hlau cov cim, mesh impressions, thiab kab sib chaws qauv

 

Yam Tseem Ceeb Rau Kev Tsim Npuag

1. Kev pab cuam lub neej ntau dhau ntawm cov ntaub ntawv tsim, ua rau txhaws mesh qhib thiab muab tub lim;

2. Ntau lub tshuab nqus tsev nqus, ua rau cov ntawv ntub dej ua kom nruj heev rau cov ntaub npuag nto thiab hloov cov cim mesh;

3. Kev xaiv tsis raug ntawm kev tsim cov ntaub ntawv lossis cov xov mesh suav, ua rau cov cim qhia los ntawm cov ntaub ntawv ntxhib;

4. Cov ntawv tsis txaus siv lub tshuab ntxhua khaub ncaws / tshuaj tsuag, ua rau cov calcium carbonate thiab cov hmoov txhuv nplej siab tso rau hauv qhov qhib mesh.

 

Xovxwm Tshooj-Cov teeb meem cuam tshuam Cov xovxwm qias neeg lossis kev dewatering tsis sib xws tuaj yeem ua rau muaj cov cim xaim nyob rau hauv daim ntawv tiav. Kev daws teeb meem thiab kev kho kom raug

1. Ua kom online siab -siab tu; ua ib qho alkaline ntxuav ntawm cov ntaub ntawv thaum lub sij hawm lub tshuab downtime.

2. Txo cov tshuab nqus tsev nyob hauv lub tshuab nqus tsev hauv cov theem.

3. Hloov cov ntaub ntawv ntawm lub sijhawm teem tseg; xaiv ib tug zoo - mesh ntaub nrog siab uniformity.

4. Seersucker-zoo li qhov tsis xws luag, huab cua npuas cim, thiab pob tshab pob.
