Raws li qhov xwm txheej tshiab ntawm Tuam Tshoj, cov yam ntxwv kev txhim kho ntawm cov hmoov nplej ua cov ntim khoom lag luam feem ntau yog raws li hauv qab no:

(1) Pulp tsim cov ntim khoom lag luam ntim khoom lag luam tau nrawm dua. Txog xyoo 2002, cov ntawv ntim khoom yas tau dhau los ua lub npe loj hauv lub tebchaws. Tshwj xeeb, txij li xyoo 2001, cov tuam txhab cuam tshuam tau loj hlob ntawm tus nqi txhua xyoo ntawm 20%. Thaum lub teb chaws cov kev cai lij choj thiab kev txwv tsis pub siv EPS tau tshaj tawm, kev thov kev lag luam rau cov hmoov sib xyaw ua cov ntim khoom lag luam yuav nce sai.

(2) Kev txhim kho cov hmoov sib sau ua cov ntim khoom muaj lub hauv paus kev lag luam zoo. Pulp tsim cov ntim khoom lag luam feem ntau siv cov thawv ntawv thawv pov tseg, cov thawv ntawv qub thiab cov ntawv xov xwm qub ua cov ntaub ntawv raw, vim tias tus nqi ntawm lub ntim nws tus kheej yog siab, yog li cov neeg siv khoom tuaj yeem lees txais tus nqi siab ntawm ntim hauv.

(3) Qhov pib nkag los ntawm cov kua txiv hmab txiv ntoo tuaj pwm ntim khoom lag luam qis, tab sis kev suav tag nrho cov txheej txheem xav tau yog siab. Pulp tsim cov txheej txheem ntim khoom lag luam xav tau kev nqis peev tsawg, cov cuab yeej siv qis thiab cov ntsiab lus thev naus laus zis. Ib qho ntxiv, raws li ib hom kev ntim khoom lag luam ntoo pulp molding, lub sijhawm tsim khoom tas li ntawm txhua qhov khoom lag luam feem ntau tsis ntev dhau, yog li nws tsis yooj yim los tshwm hauv tib cov khoom lag luam tus nqi sib tw.

Ib qho ntxiv, cov khoom ntim khoom lag luam ntim cov khoom lag luam muaj cov duab geometric nyuaj, ntim loj tom qab tib hom ntim khoom ntim, thiab cov nqi thauj mus los ntev-siab. Yog li ntawd, cov khoom tsim qauv, tsim pwm, kev qhia ua haujlwm, txheej txheem txheej txheem thiab kev txhim kho kev lag luam yuav tsum raug txiav txim siab, thiab tag nrho cov txheej txheem kev xav tau yog qhov siab.
