Qhov ntom thiab tuab ntawm cov hnab yas ntim khoom

Qhov ntom ntawm cov hnab ntim cov hnab yas feem ntau yog txiav txim siab los ntawm cov khoom siv raw khoom siv; cov ntaub ntawv sib txawv muaj ntau qhov sib txawv. Common materials such as PE and PP have relatively low densities, resulting in lightweight packaging bags-a key factor contributing to their widespread use. Feem ntau, qhov ceev yog txhais raws li qhov loj ntawm cov khoom ib chav tsev ntim thiab qhia txog cov yam ntxwv ntawm cov khoom yas nws tus kheej. Thaum xaiv cov khoom ntim, ib qho yuav tsum ua tib zoo xav txog yam xws li cov khoom muaj zog, qhov hnyav, thiab kev siv tshwj xeeb.

 

 

Lub thickness ntawm cov hnab yas ntim khoom feem ntau ntsuas hauv micrometers (μm) lossis millimeters (mm). Thickness ncaj qha cuam tshuam rau cov khoom siv lub zog, yoog raws, thiab thauj khoom- muaj peev xwm. Cov hnab tuab feem ntau muab cov tensile thiab tsim kua muag ua haujlwm zoo, ua rau lawv haum rau cov khoom hnyav dua, thaum lub hnab nyias nyias nyias thiab xav tau cov khoom siv tsawg, ua rau lawv zoo tagnrho rau cov khoom sib zog. Txawm li cas los xij, ntau dua thickness tsis yog ib txwm nyiam; Qhov zoo tshaj plaws thickness yuav tsum tau txiav txim raws li lub hom phiaj daim ntawv thov.

 

Txawm hais tias qhov ntom thiab tuab yog ob qho tib si tseem ceeb rau cov hnab ntim khoom yas, lawv sawv cev rau cov yam ntxwv sib txawv. Qhov ntom ntom qhia txog cov khoom siv hauv lub cev ntawm cov khoom siv yas, qhov tuab cuam tshuam rau lub hnab cov qauv thiab cov khoom siv. Thaum siv cov khoom siv tib yam, nce qhov tuab feem ntau nce qhov hnyav ntawm ib chav tsev; conversely, lub hnab ua los ntawm cov khoom sib txawv ntawm qhov sib txawv yuav txawv ntawm qhov hnyav txawm tias lub thickness tseem nyob tas li. Yog li ntawd, ob qho tib si cov khoom ntom ntom thiab cov yeeb yaj kiab thickness yuav tsum raug txiav txim siab thaum lub sijhawm tsim cov txheej txheem ntim khoom.

 

Thaum lub sij hawm tsim khoom, lub thickness ntawm lub hnab ntim yas yuav tsum tau saib xyuas kom zoo ib yam ntawm lub hnab thiab kom tsis txhob muaj cov cheeb tsam uas nyias nyias lossis tuab. Cov thickness tsis txaus tuaj yeem cuam tshuam lub hnab lub zog, ua rau muaj peev xwm tawg thaum siv, thaum lub thickness ntau ua rau cov khoom siv thiab cov nqi tsim khoom. Yog li ntawd, tswj kev ceev thiab tuab kom zoo txo ​​cov khoom pov tseg thaum tswj kev ua haujlwm, ua kom pom kev sib npaug ntawm lub zog, qhov hnyav, thiab tus nqi.
