Cov Txheej Txheem Tseem Ceeb Tshaj rau Daim Ntawv Tshuab Felt Xaiv

Xaiv qhov tsim nyog rau lub tshuab ntawv yog ib kauj ruam tseem ceeb hauv kev ua kom cov ntawv zoo thiab ua haujlwm tau zoo. Hauv qab no yog cov ntsiab lus tseem ceeb los xav txog thaum xaiv, nrogntawv hauv paus hnyavyog ib qho tseem ceeb ua ntej uas txiav txim siab qhov kev xav ntawm tus qauv thiab kev ua tau zoo.

1. Paper Basis Nyhav thiab Grammage

Daim ntawv lub hauv paus hnyav ncaj qha dictates qhov xav tau qhov kev xav tau ntawm kev thauj khoom thiab kev sib tw dewatering.

• Cov ntaub ntawv hnyav hnyav(piv txwv li, cov ntaub so ntswg, lub teeb yuag daim ntawv luam ntawv): nyias nyias, tsis muaj zog, thiab nquag tawg.
  • Xav tau kev xav uas yogsoft-texturedthiabsmooth-surfacekom txo qis hnav thiab crushing ntawm daim ntawv web.
  • Felts yuav tsum muajzoo huab cua permeabilitylos xyuas kom meej dewatering sai thiab tsis txhob over-compression ntawm lub vev xaib.
• Cov ntaub ntawv hnyav hnyav(piv txwv li, daim ntawv, daim ntawv tshwj xeeb): tuab, cov ntsiab lus ntawm cov dej noo, thiab cov txheej txheem ruaj khov dua.
  • Yuav tsum tau hnov ​​nrogruaj khovthiabzoo heev compression kujkom tiv taus siab dua linear.
  • Felts yuav tsum muajmuaj peev xwm tuav dej txausthiabdej conductivity zoorau kev tshem tawm cov dej loj loj.

2. Hom ntawv thiab cov kev xav tau zoo

Cov qib ntawv sib txawv xav tau cov khoom sib txawv.

• Cultural/Printing Paper: Cov kev xav tau siab raunto smoothnessthiabtsis sib xws.
  • Felts yuav tsum muajnplua-ntothiabhuv sikom tsis txhob tso cov ntawv sau los yog stains rau ntawm daim ntawv.
• Ntim Cov Ntawv / Paperboard: Cov kev xav tau siab rauzogthiabtawv, nrog qis dua xav tau ntawm qhov chaw smoothness.
  • Felts yuav tsum muajhnav-resistantthiabstructurally ruaj khovkom ua siab ntev ntev, siab siv zog nias.
• Daim ntawv: Cov kev xav tau siab rausoftnessthiababsorbency.
  • Felts yuav tsum yogsoft-texturednrogtsawg fiber ntau sheddinglos xyuas kom cov ntawv xav tau thiab huv.

3. Daim Ntawv Tshuab Parameters

Cov kev ua haujlwm tsis ua haujlwm ntawm lub tshuab ntawv ncaj qha cuam tshuam rau kev xav lub neej thiab kev ua haujlwm.

• Tshuab ceev: Siab ceev xav tau feels nrog superiorhnav tsis kam, qaug zog kuj, thiabruaj khov.
  • Cov tshuab ceev ceev feem ntau sivkoob-punched feltsvim lawv cov qauv ruaj khov thiab tsis kam mus deformation.
• Nias Hom:
  • Pas nias: Yuav tsum tau hnov ​​nrog zoocompression tsis kamthiabelasticity.
  • Nqus nias / Khau nias: Felts yuav tsum muaj zoo heevhuab cua permeabilitythiab compatibility nrog khau phaj.
  • Khau nias, tshwj xeeb, xav tau xav nrogzoo kawg nkaus lateral dej ntwsthiabtsis kam mus tas li compression teeb.
• Linear Siab: Siab dua linear siab nyob rau hauv xovxwm seem yuav tsum tau felts nrog enhancedsiab tsis kam, lub zog muaj zog, thiabseem stability.

4. Felt Properties

Lub cev thiab tshuaj lom neeg cov khoom ntawm kev xav nws tus kheej yog cov txheej txheem tseem ceeb rau kev xaiv.

• Hom qauv:
  • Woven Felts: Cov qauv ruaj khov, lub neej ua haujlwm ntev, haum rau cov tshuab qis qis, dav dav lossis cov uas ua cov ntawv loj-cov ntawv hnyav.
  • Koob-Punched Felts: Elastic, breathable, thiab yooj yim rau nruab, cov no yog cov feem ntau siv hom, zoo tagnrho rau high-ceev tshuab.
• Base Fabric Structure:
  • Ib txheej puag ntaub: Tus nqi tsim nyog, tsim nyog rau kev siv qis-qhov hnyav, kev siv ceev ceev.
  • Ob chav / multi-layer puag ntaub: Siab zog thiab ruaj khov, muaj peev xwm tiv taus siab dua linear siab, zoo tagnrho rau high-basis-hnyav, high-speed machinery.
• Khoom siv:
  • Cov ntaub plaub: Zoo elasticity, siab noo noo nqus, mos nto, tab sis kim nrog tsis zoo hnav tsis kam.
  • Nylon: Zoo hnav tsis kam, siab zog, thiab zoo elasticity - cov khoom siv tseem ceeb rau rab koob punched felts.
  • Polyester: High-temperature resistance, haum rau cov tshuab ziab khaub ncaws lossis qhov chaw kub kub.
• Cua Permeability thiab Thickness:
  • Huab cua permeability yuav tsum phim cov ntawv qib thiab tshuab ceev kom ntseeg tau tias dewatering efficiency.
  • Thickness cuam tshuam rau qhov xav tau lub peev xwm tuav dej thiab compression-rov qab ua haujlwm.

5. Tus nqi ua haujlwm thiab kev saib xyuas

• Kev Pabcuam Lub Neej: Muaj feem cuam tshuam ncaj qha rau lub sijhawm poob thiab hloov cov nqi.
• Kev Kho Kom Zoo: Yooj yim ntawm kev ntxuav thiab tiv thaiv cov nyiaj tso tawm cuam tshuam cov nqi ua haujlwm txhua hnub.
• Tus nqi tag nrho ntawm kev muaj tswv: Xav txog tus nqi yuav khoom, kev pab cuam lub neej, thiab cov nqi kho mob kom xaiv qhov kev xaiv zoo tshaj plaws.
