Dab tsi yog qhov tseem ceeb rau cov chaw tsim khoom lag luam los txiav txim siab qhov zoo ntawm daim ntawv tais? Koj puas paub tias cov tais ntawv ua li cas? Vim li cas cov ntawv tais tuaj yeem tsim thaum lub sijhawm tsim khoom? Cia peb saib cov xwm txheej uas txiav txim siab qhov tsim ntawm daim ntawv tais.
Ua ntej, qhov ceev ntawm laminate nyob ntawm seb hom fiber ntau, kev sib tsoo thiab kev ua haujlwm, uas txiav txim siab huab cua permeability thiab ntau ntawm cov ntawv tais.
Qhov thib ob, qhov℃ntawm fiber ntau entanglement txiav txim siab lub zog ntawm daim ntawv txhawb cov khoom nyob rau hauv cov thickness kev taw qhia thiab kab rov tav kev taw qhia.
Qhov thib peb, qhov sib txawv ntawm cov qauv ntawm qhov chaw thiab qhov nruab nrab ntawm lub laminate, nrog rau qhov sib txawv ntawm lub lim dej (sab ntawm lub laminate ze rau ntawm txoj hlua hlau) thiab qhov tsis yog -filter nto, yog vim qhov tseeb tias cov fibers zoo thiab cov khoom siv xws li cov khoom ntim thiab cov khoom siv ntxiv yog lim Cov txheej txheem khaws cia ntawm qhov chaw qis qis, thiab cov txheej txheem khaws cia ntawm cov txheej txheem yuav maj mam nce ntxiv. lub lim dej.
Thib plaub, kev taw qhia ntawm cov txheej txheem fiber ntau txiav txim siab anisotropy ntawm cov khoom txhawb nqa ntawv.
Lub tuam txhab siv lub luag haujlwm ntawm kev tshem tawm cov pa phem dawb thiab rov tsim ib puag ncig tshiab, zom thiab nqus tau qee cov thev naus laus zis hauv tsev thiab txawv teb chaws, thiab molding ntuj pulp rau ntau yam duab. Tsis muaj kuab paug thaum lub sijhawm tsim khoom, thiab cov khoom tuaj yeem rov ua dua thiab rov siv dua, uas yog lwm txoj hauv kev rau cov yas foamed. Cov khoom.
