Abstract

Tsab ntawv xov xwm no muab ib qho kev soj ntsuam hauv -qhov tob ntawm cov hauv paus ntsiab lus ntawm kev ua haujlwm, cov qauv kev ntsuas tseem ceeb (txoj kev gravimetric thiab infrared sensor txoj kev), kev txiav txim siab tseem ceeb ntawm kev yuav khoom, thiab ntau- kev lag luam daim ntawv thov ntawm Water Vapor Transmission Rate (WVTR) Tester (tseem hu ua Moisture Permeability Tester). Nws muaj cov txheej txheem WVTR kev tshuaj ntsuam xyuas kom paub meej cov khoom thaiv thiab kev nyab xeeb ntawm cov khoom ntim.

1. Nkag siab txog tus nqi xa mus rau dej vapor: Vim li cas nws thiaj li ua "Tus Saib Xyuas Zoo" rau cov khoom?

Xav txog ib pob ntawm cov ncuav qab zib uas hloov mus rau qhov muag vim qhov nqus dej noo, ib ntsiav tshuaj uas poob nws cov txiaj ntsig vim qhov ntub dej, lossis lub tsho "ua pa" sab nraum zoov uas ua rau tus neeg hnav tsis xis nyob thaum ua haujlwm. Lub hauv paus ua rau cov teeb meem no feem ntau yog nyob rau hauv cov dej vapor barrier tsis txaus ntawm cov ntaub ntawv siv. Dej Vapor Transmission Rate yog qhov tseeb ntawm lub cev tseem ceeb uas ntsuas qhov muaj peev xwm ntawm cov ntaub ntawv no.

Dej Vapor Transmission Rate Tester, tus kws tshaj lij hu ua Moisture Permeability Tester, yog ib lub tshuab kuaj xyuas tshwj xeeb tsim los ntsuas qhov ntsuas no kom raug. Nws ua lub luag haujlwm ntawm "tus neeg saib xyuas zoo" rau cov khoom lag luam xws li cov khoom noj, tshuaj, khoom siv kho mob, cov khoom siv hluav taws xob, lub zog tshiab, thiab cov khoom ntim khoom. Nws yog ncaj qha ntsig txog lub txee lub neej, kev nyab xeeb, kev ua haujlwm, thiab kev ntseeg siab ntawm cov khoom.

2. Cov Ntsiab Lus Qhia: Tus Dej Vapor Transmission Rate Tester ua haujlwm li cas?

Tam sim no, cov thev naus laus zis ntawm WVTR kev sim thev naus laus zis hauv kev ua lag luam feem ntau tau muab faib ua ob hom hauv qab no, uas ua ke ua lub hauv paus txheej txheem rau kev ntsuam xyuas cov dej noo permeability ntawm cov ntaub ntawv.

2.1 Gravimetric Method (Cup Method)

Txoj Cai: Cov qauv no tau muab ntim rau hauv cov dej noo-permeable khob uas muaj cov desiccant lossis dej distilled. Lub khob tau muab tso rau hauv qhov chaw sim nrog qhov kub thiab txias. Tus nqi ntawm cov dej vapor kis tau los ntawm cov qauv yog xam los ntawm lub sij hawm ntsuas qhov kev hloov ntawm qhov hnyav ntawm cov dej noo-permeable khob.

Cov Khoom Muag Khoom: Shounuo SN-W01 / SN-W103 Water Vapor Transmission Rate Testers.

Qhov tsis zoo: Lub voj voog ntawm kev xeem yog ntev, qhov℃ntawm automation yog tsawg, thiab cov txiaj ntsig tau raug cuam tshuam rau kev tuav haujlwm thiab kev hloov pauv ib puag ncig.

Cov qauv siv tauGB / T 1037, ASTM E96, JIS Z0208, thiab lwm yam.

2.2 Infrared Sensor Method

Txoj Cai: Nws siv cov yam ntxwv ntawm cov dej vapor absorbing infrared rays ntawm tej wavelengths. Cov qauv yog clamped nyob rau hauv ib qho kev xeem chamber. Ib sab ntawm lub chamber yog qhov siab - ib puag ncig cov av noo, thiab sab nraud yog ntim nrog cov pa roj qhuav (xws li nitrogen). Tom qab dej vapor dhau los ntawm cov qauv, nws yog nqa mus rau lub infrared sensor los ntawm cov cab kuj gas. Cov dej vapor kis tus nqi yog ncaj qha thiab raug xam los ntawm kev kuaj xyuas qhov kev hloov pauv ntawm qhov nqus infrared.

Cov Khoom Muag Khoom: Shounuo SN-H Series Dej Vapor Transmission Rate Testers (piv txwv li, SN-H01, SN-H03)

Nta:

Qhov zoo: Kev soj ntsuam siab raug, ceev ceev, rov ua tau zoo, kev ntsuas dav dav, thiab qib siab ntawm automation thiab kev txawj ntse.

Qhov tsis zoo: High technical threshold rau cov khoom siv thiab cov nqi yuav khoom siab.

Cov qauv siv tauASTM F1249, ISO 15106-2, GB / T 26253, TAPPI T557, thiab lwm yam.
