Qhov loj me: 787 * 1092MM, 889 * 1194MM yog nyob rau hauv Tshuag.Lub sij hawm xa khoom dav dav rau kev ua thiab kev teeb tsa yog 3-5 hnub, thiab cov kev cai tshwj xeeb tshwj xeeb yog li 7-15 hnub

Nta: Daim ntawv saum npoo yog zoo, du thiab nruab nrab, nrog zoo nruj, ncaj, txaus thickness, toughness thiab tsis yooj yim rau deform.
Vim muaj cov txheej txheem tshwj xeeb thiab kev tswj xyuas nruj nruj, txhua yam khoom muaj cov yam ntxwv ntawm lub teeb yuag, zoo nruj, thiab tsis yooj yim rau deform.Tshwj xeeb tshaj yog nyob rau hauv lub microwave drying txheej txheem, ib tug sterilization txheej txheem kuj ua tiav, yog li nws yog ntau thiab ntau nrov nyob rau hauv kev lag luam ntim khoom noj.Ntsuab ignorance.Qhov saum npoo ntawm cov khoom yog du thiab muag heev, thiab qhov tawv nqaij yog qhov zoo.

1. Quantitative
Nws yog hais txog qhov hnyav ntawm ib cheeb tsam ntawm daim ntawv, qhia hauv g / m2, uas yog, gram hnyav ntawm ib square meter ntawm daim ntawv.Qib ntau ntawm daim ntawv txiav txim siab lub cev ntawm daim ntawv, xws li lub zog tensile, tsim kua muag, nruj, nruj thiab tuab.Yog li ntawd, raws li cov yam ntxwv ntawm cov cuab yeej siv, kev npaj cov khoom lag luam ntau raws li nws cov kev ua tau zoo rau kev tsim khoom tuaj yeem txo qis kev noj thiab txhim kho cov khoom zoo thiab kev ua haujlwm ntawm cov khoom siv.

2. Thickness
Nws yog qhov tuab ntawm daim ntawv, thiab chav ntsuas ntsuas feem ntau yog qhia hauv ㎜.Thickness yog ze ze rau qhov ntau thiab nruj.Feem ntau hais lus, qhov loj dua qhov tuab ntawm daim ntawv, qhov sib txuam ntau ntau, tab sis kev sib raug zoo ntawm ob tsis yog qhov tseeb.Qee cov ntawv nyias nyias, tab sis lawv qhov hnyav yog sib npaug los yog ntau dua li cov tuab tuab.Qhov no qhia qhov nruj ntawm cov qauv fiber ntau ntawm daim ntawv, uas txiav txim siab lub hauv paus hnyav thiab thickness ntawm daim ntawv.Los ntawm qhov pom ntawm kev siv cov nyhuv, nws yog ib qho tseem ceeb heev uas lub thickness ntawm daim ntawv yog uniform.Txwv tsis pub, nws yuav cuam tshuam rau cov ntawv tsis siv neeg pub, gluing evenness, thiab lwm yam.

3. Ceev ceev
Nws hais txog qhov hnyav ntawm daim ntawv ib lub cubic centimeter, hauv g / cm3.Qhov nruj ntawm daim ntawv yog xam los ntawm lub hauv paus hnyav thiab tuab raws li cov qauv hauv qab no: D = G / d * 1000, qhov twg: G qhia qhov hnyav ntawm daim ntawv;g yog daim ntawv thickness.
Qhov nruj yog ib qho kev ntsuas ntawm qhov ntom ntawm daim ntawv qauv.Yog hais tias lub nruj dua loj heev, daim ntawv yuav yooj yim tau nkig, cov opacity thiab dej nqus yuav raug txo qis, thiab nws yuav tsis yooj yim kom qhuav.
Nws kuj yog ib qho yooj yim los xam cov duab los qhia thickness raws li cov qauv saum toj no.Nws cov qauv yog: d = G / D.
Piv txwv li: Nrhiav lub thickness ntawm 500g / m2 ob chav grey cardboard (nws qhov nruj tab yog 0.625g / cm3, uas yog ib qho tseem ceeb qhia peb).500g / m2 ÷ 0.625g / cm3 = 0.0008m = 0.8 hli
Chav tsev hloov dua siab tshiab ntawm m2 thiab cm3 hais hauv cov kauj ruam dhau los yuav tsum tau khaws cia hauv siab, txwv tsis pub nws yooj yim ua rau kev nkag siab yuam kev.Cov txheej txheem yog: cm3 / m2 = (1 * 0.000001) m, hloov mus rau mm yog peb cov thickness tiag tiag.

4. Nyuaj
Nws yog qhov ua tau zoo ntawm daim ntawv tiv thaiv qhov indentation ntawm lwm yam khoom, thiab nws kuj yog qhov roughness ntawm cov ntaub so ntswg ntawm daim ntawv.

5. Smoothness
Nws yog hais txog qhov tsis sib xws ntawm qhov chaw ntawm daim ntawv, qhia hauv vib nas this, uas yog ntsuas tau.Lub hauv paus ntsiab lus ntawm kev tshawb nrhiav yog: nyob rau hauv ib qho kev nqus ntawm lub tshuab nqus tsev thiab lub siab, lub sij hawm nws yuav siv sij hawm rau cov huab cua ntawm cov kuab tshuaj kom dhau los ntawm qhov sib txawv ntawm cov iav phaj thiab qhov chaw ntawm cov qauv.Lub smoother ntawm daim ntawv, qhov qeeb ntawm huab cua yuav dhau mus, thiab qhov ceev cua yuav dhau mus.

6. Scaling tus nqi
Nws hais txog qhov sib txawv ntawm daim ntawv tom qab nqus dej los yog dej poob.Qhov softer cov qauv fiber ntau ntawm daim ntawv thiab qhov qis dua qhov nruj, qhov siab dua qhov ncab ntawm daim ntawv;ntawm qhov tsis sib xws, qhov qis dua tus nqi ncab.

7. Cov ntsiab lus noo noo
Moisture cov ntsiab lus nyob rau hauv cardboard.Feem ntau hais lus txheem.Cov dej noo ntawm ob chav grey cardboard yog 8-12%.

8. Vertical thiab kab rov tav
Nws yog hais txog cov kev taw qhia nyob rau hauv uas cov ntaub so ntswg fibrous ntawm daim ntawv yog teem.Nyob rau hauv cov txheej txheem papermaking, cov kev taw qhia ntawm cov fibers raws txoj kev khiav ntawm lub tshuab ntawv yog lub longitudinal kev taw qhia ntawm daim ntawv.Nws tuaj yeem raug txheeb xyuas los ntawm lub kaum ntse ntse uas nthuav tawm los ntawm lub vev xaib.Ntsug mus rau txoj kab ntsug yog txoj kab rov tav, qhov deformation tus nqi ntawm daim ntawv ntsug yog qhov me me, thiab qhov kev nthuav dav thiab kev cog lus thaum siv cov ntawv kab rov tav yog qhov loj.

9. Cua permeability
Feem ntau, daim ntawv nyias nyias thiab tsis nruj, qhov ntau breathable.Chav tsev ntawm huab cua permeability yog ml / mim los yog s / 100ml (thib ob / 100ml), uas txhais tau hais tias cov huab cua uas dhau los ntawm daim ntawv nyob rau hauv 1 feeb los yog lub sij hawm nws yuav siv sij hawm kom dhau 100ml ntawm huab cua.

10. Pem hauv ntej thiab nraub qaum
Thaum lub sij hawm papermaking, lub pulp adheres rau steel mesh thiab yog yus muaj los ntawm filtering thiab dewatering.Nyob rau hauv txoj kev no, yog tias sab ntawm lub net poob vim qhov poob ntawm cov fibers zoo thiab cov khoom ntim nrog dej, cov qhab nia tau raug tso tseg, thiab daim ntawv saum npoo yog thicker.Ntawm qhov tod tes, nws yog qhov zoo yam tsis muaj kev cia siab rau lub vas.Smooth, kom cov ntawv tsim qhov sib txawv ntawm sab xub ntiag thiab sab nraub qaum.Txawm hais tias nws tau qhuav thiab calendered nyob rau hauv ntau lawm, tseem muaj qhov sib txawv nyob rau hauv pem hauv ntej thiab nram qab.
