Lub thickness ntawm ib lub siab - lub siab tiaj lub hnab feem ntau yog hais txog lub thickness ntawm ib sab, tsis yog ua ke thickness ntawm ob sab. Cov qauv no muaj ntau nyob rau hauv kev lag luam ntim khoom.
Tshwj xeeb, lub thickness parameter ntawm lub siab - lub hnab ntim siab qhia lub thickness ntawm ib txheej ntawm cov khoom, feem ntau ntsuas nyob rau hauv millimeters (mm) los yog micrometers (μm). Piv txwv li, ib lub hnab tiaj tiaj nrog lub thickness ntawm 0.04 hli txhais tau hais tias lub thickness ntawm cov khoom ntawm ib sab yog 0.04 hli, tsis yog lub thickness ntawm ob sab (0.08 hli). Cov qauv no pab cov neeg siv kom nkag siab zoo txog lub cev cov yam ntxwv ntawm cov khoom thaum yuav khoom.
Los ntawm kev pom kev, lub thickness ntawm lub siab - lub hnab ntim siab yog ze ze rau nws cov ntaub ntawv, txheej txheem tsim khoom, thiab daim ntawv thov. Hais txog cov ntaub ntawv, siab - lub hnab ntim siab feem ntau siv cov thermoplastics xws li polyethylene (PE), polypropylene (PP), lossis biaxially oriented polypropylene (BOPP). Cov ntaub ntawv no tau ua tiav rau hauv cov yeeb yaj kiab uas siv cov tshuab cua tshuab lossis cov txheej txheem cam khwb cia, thiab tom qab ntawd txiav thiab kaw kom tsim cov khoom tiav. Thickness ncaj qha cuam tshuam lub hnab lub zog thiab kav ntev. Cov ntaub ntawv tuab dua muab kev tiv thaiv ntau dua thiab thauj khoom- cov kabmob muaj peev xwm, ua rau lawv tsim nyog rau cov ntawv thov uas xav tau kev tiv thaiv cov khoom sab hauv, xws li ntim cov khoom siv hluav taws xob thiab cov khoom siv kho mob. Nyob rau hauv daim ntawv thov scenarios, lub thickness ntawm siab - siab flat hnab yuav tsum raug xaiv raws li cov kev xav tau tshwj xeeb. Piv txwv li, lub hnab tiaj tus nrog lub thickness ntawm 0.02mm feem ntau yog siv los ntim cov khoom hnyav xws li cov ntawv sau thiab cov khoom me me; thaum cov tuab dua 0.05mm yog tsim rau cov khoom noj, khoom siv txhua hnub, thiab lwm yam xwm txheej uas yuav tsum tau muaj kev tiv thaiv ntau dua. Tsis tas li ntawd, thickness kuj cuam tshuam rau lub hnab yooj yooj yim thiab pob tshab. Cov ntaub ntawv nyias nyias yog hloov tau yooj yim dua tab sis yooj yim puas, thaum cov ntaub ntawv tuab yog nruj dua thiab tsim kua muag- tiv taus tab sis tuaj yeem txo qhov pom tseeb.
Hais txog cov qauv kev lag luam, lub thickness ntawm siab - lub hnab ntim siab yuav tsum ua tau raws li lub teb chaws lossis thoob ntiaj teb cov txheej txheem zoo. Piv txwv li, hauv kev ntim khoom noj, cov hnab nyias nyias yuav ua rau tawg, ua rau muaj kev sib kis ntawm cov khoom; thaum nyob rau hauv kev lag luam ntim khoom, thickness tsis txaus yuav tiv thaiv lub hnab los ntawm withstanding lub siab ntawm cov khoom hnyav. Yog li ntawd, cov neeg siv yuav tsum xaiv qhov tsim nyog thickness specification raws li lawv cov kev xav tau tiag tiag. Hauv cov xwm txheej tshwj xeeb, xws li siab - qhov kub thiab txias ib puag ncig, cov ntaub ntawv tshwj xeeb lossis cov qauv tsim yuav tsum tau ua kom ruaj khov.
Nws yog tsim nyog sau cia tias qee cov khoom lag luam tuaj yeem siv tag nrho cov tuab ntawm ob sab raws li tus nqi nominal, tab sis qhov no tsis tshua muaj. Cov neeg siv yuav tsum ua tib zoo xyuas cov khoom tsis zoo thaum yuav khoom kom tsis txhob muaj kev nkag siab yuam kev txog cov tuab uas yuav cuam tshuam rau cov khoom ua haujlwm. Rau cov xwm txheej uas xav tau lub zog siab lossis kev ua haujlwm tshwj xeeb, nws raug nquahu kom xaiv cov khoom nrog lub thickness ntau dua 0.04mm, thiab muab qhov tseem ceeb rau siab -siab lub hnab ntim nrog cov tshuaj tiv thaiv- zoo li qub thiab ya raws- pov thawj ua haujlwm.
