Paper tshuab felts yog cov khoom tseem ceeb hauv cov txheej txheem papermaking, ncaj qha cuam tshuam rau daim ntawv zoo, kev ua haujlwm ntau lawm, thiab cov nqi ua haujlwm. Raws li cov txheej txheem ntau yam-xws li lawv txoj haujlwm ntawm lub tshuab ntawv, txoj kev xaws, cov qauv ntaub hauv qab, cov ntawv siv tau, thiab cov haujlwm tshwj xeeb-cov ntawv tshuab muaj peev xwm muab faib ua ntau hom, txhua tus muaj cov khoom tshwj xeeb thiab lub hom phiaj.
1. Kev faib tawm los ntawm Txoj Haujlwm ntawm Daim Ntawv Tshuab
Qhov no yog qhov tseem ceeb tshaj plaws kev faib tawm, feem ntau raws li qhov xav tau qhov chaw nyob hauv cov txheej txheem papermaking:
- Wet Felt: Feem ntau yog siv rau hauv cov xovxwm, nws ncaj qha hu rau cov ntaub ntawv ntub dej tshiab. Nws lub luag haujlwm tseem ceeb yog nyem dej tawm ntawm lub vev xaib los ntawm kev siab thiab pib ua kom zoo nkauj ntawm daim ntawv.
- Sab saum toj Felt: Muab tso rau saum cov ntaub ntub dej, nrog qee qhov chaw hu rau lub tshuab ziab khaub ncaws. Ntxiv nrog rau kev pab hauv dewatering, nws coj cov ntawv web, flattens nws, thiab ceev kom qhuav.
- Tshuab ziab khaub ncaws: Feem ntau qhwv ib ncig ntawm lub tshuab ziab khaub ncaws, nws irons thiab dries daim ntawv tom qab nias, ua ib feem tseem ceeb ntawm cov txheej txheem ziab.
2. Kev faib tawm los ntawm Txoj Kev Weaving
Txoj kev weaving txiav txim siab cov qauv tsim thiab cov yam ntxwv ntawm kev ua haujlwm:
- Woven Felt: Ua los ntawm cov xov paj sib xyaw ntawm cov ntaub plaub thiab cov nylon staple fibers, ua raws li cov txheej txheem ib txwm muaj xws li kev xaws, puv, napping, ziab, thiab teeb tsa. Nws nta cov qauv ruaj khov thiab ua haujlwm ntev.
- Koob-Punched Felt: Cov ntaub nonwoven ua los ntawm carding fibers rau hauv ib lub web, sib tshooj ntau txheej, thiab tom qab ntawd siv barbed steel koob los tho lub web fibers rau hauv ib qho kawg puag ntaub, entangling fibers. Needle-punched felts muab cov huab cua permeability zoo thiab elasticity, ua rau lawv siv dav hauv cov tshuab ntawv niaj hnub.
3. Kev faib tawm los ntawm Base Fabric Structure
Lub hauv paus ntaub txhawb nqa cov qauv tseem ceeb, thiab nws cov qauv tsim ncaj qha cuam tshuam rau qhov kev xav tau ruaj khov thiab ruaj khov:
- Ib txheej Base Fabric Felt: Zoo li yooj yim hauv cov qauv thiab tus nqi tsim nyog, tsim nyog rau cov ntawv thov uas tsis muaj ntawv zoo.
- Ob chav txheej Base Fabric Felt: Ua los ntawm ob sab saum toj thiab hauv qab lub hauv paus ntaub khaubncaws sab nraud povtseg, nws boasts siab zog thiab seem stability, ua rau nws tiv taus ntau zog thiab nro.
- Laminated Base Fabric Felt: Muab faib ua cov qauv xws li 1+1, 1+2, 2+1, thiab 1+1+1 raws li tus naj npawb thiab hom laminated puag fabrics. Hom no muab cov txiaj ntsig zoo ntawm cov khaubncaws sab nraud povtseg kom tau raws li qhov xav tau ntawm kev ua haujlwm siab thiab kev ua haujlwm siab ntawm cov txheej txheem papermaking.
4. Kev faib tawm los ntawm Daim Ntawv Qhia Qib
Cov ntawv sib txawv tsim cov kev cai sib txawv ntawm kev ua haujlwm zoo:
- Ntim Ntawv Felt: Siv los tsim cov khoom ntim xws li cov ntawv corrugated thiab cov thawv ntim khoom. Nws yuav tsum tau hnav tsis kam thiab load-bearing muaj peev xwm.
- Cultural Paper Felt: Haum rau cov ntawv xov xwm, ntawv sau ntawv, thiab cov ntawv luam ntawv, uas xav tau kev ua kom zoo thiab sib xws. Yog li, qhov xav tau yuav tsum muaj cov khoom zoo heev thiab dewatering efficiency.
- Daim Ntawv Tshwj Xeeb Felt: Tsim los rau cov txheej txheem tsim khoom tshwj xeeb ntawm cov ntawv tshwj xeeb (piv txwv li, lim ntawv, ntawv insulating, ntawv zoo nkauj). Nws feem ntau xav tau cov khoom tshwj xeeb xws li kub-kub tsis kam, corrosion kuj, lossis tshwj xeeb huab cua permeability.
- Cov ntaub ntawv Felt: Siv rau daim ntawv tso quav tso quav, cov ntaub so ntswg, thiab lwm yam. Nws yuav tsum yog mos kom ntseeg tau tias daim ntawv bulkiness thiab absorbency.
5. Kev faib tawm los ntawm Kev Ua Haujlwm Tshwj Xeeb
Hauv cov ntu tshwj xeeb ntawm lub tshuab ntawv, cov ntaub ntawv tau muab faib ntxiv los ntawm lawv lub luag haujlwm:
- Xovxwm Section Felts: Piv txwv suav nrog "thawj xovxwm sab saum toj xav," "thawj xovxwm hauv qab xav," thiab "nqus xovxwm xav," sib xws rau cov xovxwm sib txawv thiab cov txheej txheem ua haujlwm hauv ntu xovxwm.
- Txoj kev ua ntu Felts: Xws li "kev xav" thiab "hloov kev xav," feem ntau yog lub luag haujlwm rau kev txhawb nqa thiab xa cov ntawv web.
- Prepress Felt: Piv txwv suav nrog "prepress sab saum toj xav" thiab "nqus prepress sab saum toj xav," siv rau kev dewatering ua ntej thiab shaping ntawm daim ntawv web ua ntej nws nkag mus rau hauv xovxwm loj.
Hauv cov ntsiab lus, lub tshuab ntawv tshuab muaj ntau hom, txhua tus tsim los rau cov hom phiaj tshwj xeeb thiab kev siv. Kev nkag siab txog cov kev faib tawm no pab cov neeg ua ntawv xaiv cov kev xav tau zoo raws li cov kev xav tau ntau lawm, yog li txhim kho kev ua tau zoo thiab cov ntawv zoo.
