Kub yaj nplaum nplaumyog 100% cov nplaum nplaum uas tsis muaj dej los yog cov kuab tshuaj. Vim nws qhov zoo xws li tsis muaj tshuaj lom, tsis muaj kuab paug, muaj kev sib txuas ceev ceev thiab tsim nyog rau kev ua haujlwm tsis siv neeg, nws tau siv dav siv maj mam. Thaum siv cov nplaum nplaum kub, cov neeg tuaj yeem ntsib qee qhov teeb meem, thiab qhov zoo tshaj plaws yog qhov kub yaj nplaum nplaum tsis ruaj khov. Niaj hnub no, cia peb txheeb xyuas cov laj thawj yog vim li cas cov nplaum nplaum kub tsis sib txuas ruaj khov.
Ua ntej, tsis suav nrog qhov muaj peev xwm muaj teeb meem zoo nrog cov nplaum nplaum kub nws tus kheej, yog vim li cas vim li cas cov nplaum kub yaj tsis sib txuas ruaj khov tuaj yeem pw hauv qhov kev xaiv tsis raug ntawm cov nplaum nplaum kub. Thaum xaiv cov nplaum nplaum kub, nws yog ib qho tsim nyog yuav tsum nkag siab tag nrho cov ntaub ntawv yuav tsum tau sib khi thiab xaiv covkub yaj nplaumraws li cov yam ntxwv ntawm cov khoom sib txuas. Siv cov nplaum nplaum kub rau cov thawv ntawv zoo li ua piv txwv. Cov ntaub ntawv ntawm phau ntawv zoo li lub thawv tuaj yeem muab faib ua ob hom: laminated thiab non-laminated. Rau cov ntaub ntawv laminated, nws yog ib qho tsim nyog yuav tau xaiv cov kua nplaum uas muaj zog permeability kom ua tiav cov txiaj ntsig zoo. Dhau li ntawm kev txiav txim siab txog hom kev sib txuas cov ntaub ntawv, nws tseem yuav tsum tau xav txog kev siv ib puag ncig ntawm cov khoom tiav. Siv cov nplaum nplaum kub rau cov roj teeb cia ua piv txwv, cov roj teeb cia yuav ua kom muaj cua sov thaum siv cov txheej txheem. Yog li ntawd, thaum xaiv cov nplaum nplaum kub, nws yog ib qho tsim nyog yuav tau xaiv cov khoom uas muaj cua sov zoo. Txhawm rau ua kom tiav, thaum cov nplaum nplaum kub tsis ruaj khov, thawj qhov yuav tsum xav txog yog seb cov nplaum nplaum uas tau xaiv yog qhov tseeb.
Thaum xaiv cov nplaum nplaum kub yog qhov tseeb, qhov thib ob, nws yuav tsum tau txiav txim siab seb txoj kev tsim kho puas yog. Thaum lub sij hawm cua sov txheej txheem, kub yaj nplaum tsuas tuaj yeem hloov nws lub cev lub zog thaum khaws nws cov khoom siv tshuaj tsis hloov. Txawm li cas los xij, cov cuab yeej no muaj qhov kub thiab txias. Yog tias cov cua sov tshaj qhov ntsuas kub no, qhov kev ua haujlwm ntawm cov kua nplaum yuav raug puas tsuaj, thiab qhov tshwm sim tshwm sim yog tias nws tsis ua haujlwm.
Muaj tseeb tiag, muaj ntau lwm yam laj thawj vim li caskub yaj nplaumtsis khi. Tsuas yog los ntawm kev nkag siab tag nrho cov laj thawj rau qhov tsis ua tiav daim ntawv cog lus tuaj yeem daws qhov teeb meem zoo dua.
